This article directory 1 construction construction internship report 2 construction construction internship report 3 construction construction internship report part 1: construction construction internship report

The first four weeks of this semester are graduation internships. Before that, we conducted internships, production internships, construction and management training. This is a graduation internship. We all value this internship because this is the last time we have an internship organized by the school during our school years. Our majors are divided into eight groups. I am in the eighth group. There is a teacher led by Hu. The teacher said that the internship site can be found by myself. Under the introduction of my classmates, I will be at the Jiaodong Tadong Community Health Service Center----Comprehensive Internship on an old house renovation site in the building. During the internship, I often keep in touch with the teacher and report the progress and experience of the internship every week. Under the enthusiastic care and guidance of the teacher, we learned a lot of knowledge that was not available in the textbook during the internship. When we encountered an incomprehensible place, we all asked the instructor in time, so we all felt great in the internship. It laid a solid foundation for future work.

On February 28, 20xx, I went to the construction site and met the project manager, Manager Liu. He was very happy to accept my intern. He arranged my work for me. My job is the construction technician in the project department. The project is an old house renovation project. The project is a comprehensive hospital building in Jiaodong Tadong Community. The number of buildings in this building is three floors. The building was built 50 years ago. There are no structural columns and ring beams in the third floor. It’s just that the floor slab is a cast-in-place concrete slab. I was amazed that the designer who used the cast-in-place concrete slab 50 years ago. The project is a reinforcement project designed by Jiaozuo Guangcheng Planning and Architectural Design Co., Ltd.; it is constructed by Henan Credit Information Construction Engineering Co., Ltd.; the supervision party is the supervision construction of Henan Jianda Engineering Construction Supervision Company. The contract period for this project is from March 1, 2019 to September 1, 2019. This internship is a good exercise for me, because I have not been exposed to the old house renovation project before, so I attach great importance to this internship.

This internship has helped me a lot in my career. Before I had an internship in brick-and-mortar structure, internships in the framework of the high-rise, internship overhauled the road; this internship was rebuilt and rebuilt, I was the first time, this aspect for me. The knowledge is a good supplement. I have learned a lot of knowledge, which has further deepened my knowledge of textbooks and created a broader space for my future work.

During the internship, I often read drawings and atlases, because I started to understand the construction of the house almost without knowing it, but after my efforts, I can understand what happened after a week, but it is still very simple. Well, just figure out the details of the construction.

Now briefly describe the knowledge you have learned at the site:

1. Introduction to seismic strengthening methods for brick-concrete structures:

Starting from the seismic mechanism of the structure, seismic reinforcement can be divided into the method of reducing seismic reinforcement, the method of strengthening the seismic capacity of the structure and the multi-channel anti-seismic reinforcement method. Reducing the earthquake is mainly achieved by increasing the structural period or increasing the structural damping. It is generally applied to the seismic strengthening of large public buildings; the reinforcement method for increasing the seismic capacity of the structure, such as the outer reinforced concrete surface that increases the seismic performance of the wall. Layer and steel mesh cement mortar surface layer reinforcement method; pressure grouting reinforcement method for increasing structural integrity, additional ring beam reinforcement method, and tie-bar reinforcement method; and addition of seismic wall to reduce seismic capacity of weak members subjected to seismic capacity Wall method, etc., these methods are relatively simple to construct, and a large number of them are used in multi-layer brick-concrete structures, especially in civil buildings. Multi-channel seismic line reinforcement is the use of multiple anti-side force systems in the building. The anti-side force of the second line or even the third line of defense after the anti-side force members of the first line of defense are damaged by strong earthquakes. The components are immediately replaced to withstand the subsequent earthquake shocks, ensuring that the building is at a minimum and free from collapse.

In terms of structural seismic strengthening methods, the seismic strengthening construction methods mainly include external reinforcement method, internal reinforcement method, and plywood wall reinforcement method. The external reinforcement method generally combines the number of layers of the masonry structure and the results of seismic identification. It is necessary to add different numbers of structural columns, ring beams, and tie rods to ensure the coordinated construction of the structural column, the ring beam and the seismic wall. This method generally does not occupy the indoor building area, and is used in residential buildings, which has less impact on the residents, but has a greater impact on the building façade; the basic principle of the internal reinforcement method is the same as the external reinforcement method, and it is also necessary to add structural columns, ring beams and Pull rods, if necessary, if the original wall is not earthquake-resistant, it is necessary to add anti-seismic wall or improve the seismic resistance of the original wall. The internal reinforcement method will not change the building facade shape, and is generally applicable to public buildings, especially street-facing buildings; The wall reinforcement method improves the seismic performance on the basis of strengthening the original wall seismic resistance. At present, the most common method is the reinforcement method of the steel mesh cement mortar surface layer, that is, the reinforcement mesh is added on one or both sides of the wall to be reinforced. Anchoring ribs, inserting short ribs, and drawing ribs, etc., connect the reinforced mesh around the slab or the girders, columns or walls.

2. How to add ring beams and structural columns.

Add a ring beam:

1) Reinforcement basis: According to Article 7.3.3 of the Code for Seismic Design of Buildings: the outer wall and the inner vertical wall are set with ring beams at each floor, and the inner cross wall is set with ring beams at each floor.

2) Reinforcement method: The ring beam has external work, internal work and on the wall. The internal work affects the appearance and use of the building, so it is chosen to be made on the wall. According to the provisions of Article 7.3.4 of the specification, the longitudinal reinforcement is not less than 4φ10, the stirrup is not less than φ6@250, and the section height is not less than 120mm.

If the distance between the lower skin of the board and the window epithelium is 300mm, which also conforms to the modulus of the brick, the height of the ring beam is 300mm, which meets the requirements of seismic specifications.

The longitudinal reinforcement is 4φ12, which meets the requirements of seismic specifications.

If the stirrups are taken as φ6@250 according to the regulations, the stirrups penetrate the wall and need to punch one hole every 250mm, which will damage the integrity of the wall and make the construction difficult. The method of increasing the diameter and spacing of the stirrups is adopted, and the stirrups φ12@600 are actually used. In order to ensure the position of the longitudinal reinforcement of the upper and lower skins, additional steel bars of φ6@300 are added on both sides of the wall.

3) Construction method: a, remove the plaster layer on both sides of the wall, full-length slotting, depth 30mm, height 300mm; b, every 600mm up and down one hole, diameter 30mm-50mm, used to pass through No. 3 steel; c. Place the No. 2 steel bar on the wall side, remove the plaster, cut the brick seam, and cut it 10-20mm deep; d, place the No. 2 longitudinal reinforcement, and tie the No. 3 stirrup to the No. 2 longitudinal reinforcement, and tie the inside After the 4th steel bar, the 2, 3, and 4 steel bars are in place, the hole is fastened with 1:3 dry hard cement mortar; e, the 1st longitudinal reinforcement is placed and tied with 3 stirrups and 4 tendons; Welded firmly, weld length lw=120mm, weld height hf=5mm; f, inner and outer sides use 1:3 dry hard cement mortar to smooth the groove on the wall, and then decorate and restore.

The height and reinforcement of the outer ring beam beam are the same as the inner wall ring beam. During construction, the brick joints are 10-20mm on the inner side of the outer wall, and the longitudinal reinforcement is placed. The other construction methods are the same as the inner wall ring beam.

4) Treatment of the intersection of vertical and horizontal walls:

On the cross wall, corresponding to the longitudinal reinforcement of the longitudinal wall ring beam, punch 30-50mm, pass the longitudinal rib of the horizontal wall ring beam and bend it horizontally, and bend the length to 30d, and tie it with the vertical rib of the vertical wall ring beam. Stuffed with 1:3 dry hard cement mortar.

Additional structural column

According to Article 7.3.2 of the specification, the minimum section size of the construction column is 240mm×180mm, the longitudinal reinforcement is not less than 4φ12, and the stirrup is not less than φ6@250. The construction of the construction column is 350×180mm, the longitudinal reinforcement is 6φ12, and the stirrup is φ6. @200.

The difficulty in making up the structural column is: first, the reliable connection with the original wall; second, how to pass through the original floor. The following are the two points respectively:

1) Connect the construction column to the original wall.

The structural columns are placed at the inner and outer walls, at the corners of the vertical and horizontal walls or at the corners of the stairs. The project uses the pin-key method combined with the bundling method to form the new structural column with the original inner and outer walls.

The pin-key method is to open a dovetail groove on the original wall body, which is small inside and outside, forming a carcass, placing steel bars in the groove, and pouring C25 high-strength self-leveling fine stone concrete. The external cavity is made of 120mm×120mm, the inner raft is made of 180×180mm, the depth is 180mm, and the 2φ10∪-shaped steel bar is placed. The body is made every 1000mm along the height direction.

The binding method is to punch holes in the wall, wear steel bars, and tie the longitudinal reinforcements of the newly constructed columns. This project is to perforate the φ12 ring steel and the longitudinal column of the structural column every 1000mm on the inner and outer walls, and pour the concrete. C25 high-strength self-leveling fine stone concrete.

2) Construct the column through the floor.

In order to ensure that the structural column is integrated in the height direction, the structural column must pass through one, two and three floors, as follows:

At the first and second floors, corresponding to the longitudinal position of the structural column, the drill hole diameter is φ30 on the floor, which is six. If it is a prestressed hollow slab, the rib should be avoided when punching, and it should be worn in each hole. -φ14 steel bar, exposed 550mm on the board and under the board. After wearing, use C30 dry hard self-leveling concrete to fill the hole. When filling and filling, fill the hole in the original plate as much as possible. After plugging, tie the longitudinal column of the structural column. Pouring concrete. The top of the main rib of the structural column is anchored into the three-story slab or beam concrete.

3) The structural column is not used as a foundation alone, and the lower part should extend to 500mm below the indoor floor.

3. Newly opened door wall reinforced mortar layer reinforcement

The masonry wall is reinforced with a reinforced mortar layer and is reinforced with one or two sides.

Process requirements:

The surface mortar strength is M10.

The thickness of the surface layer of the steel mesh mortar is 35mm, the thickness of the outer protective layer of the steel bar is not less than 10mm, and the gap between the steel mesh and the wall is not less than 5mm.

The steel bar has a steel bar diameter of Φ6, a grid line solid wall of 300*300mm, and an empty wall of 200*200mm.

The single-sided plus surface layer adopts L-shaped anchor rib of Φ6, and the S-shaped through-wall rib of Φ6 is used on both sides; the spacing of L-shaped anchor bars is 600mm, the spacing of S-shaped through-wall bars is 900mm, and the plum-shaped arrangement is arranged.

When the transverse steel bars of the steel mesh meet the door and window openings, the single-sided reinforcement should be bent into the window hole side anchoring, and the double-sided reinforcement should close the steel bars on both sides.

Construction sequence:

The original wall decoration layer is cut away - drilling and washing with water - laying the steel mesh and installing the anchor ribs - watering the wet wall surface - smearing the cement mortar and curing it.

Construction control points:

When the original wall surface is seriously corroded, the loose part should be removed first, and the surface should be wiped with 1:3 cement mortar. The original loose joint mortar should be removed.

Drill holes in the wall, mark the position of the anchors according to the scheme, and drill with electric drills. The diameter of the through hole is 2mm larger than the S anchor. The diameter of the anchor hole should be twice the diameter of the anchor. The depth of the hole should be 100mm. After the anchor is inserted into the hole, it is filled with cement mortar.

Vertical reinforcement should be placed against the wall when laying steel mesh.

Before smearing the cement mortar, first make a cement slurry on the wall and then layer the plaster. The thickness of each layer should not exceed 15mm.

The top layer should be watered for curing.

4. Reinforcement of the original window.

The reinforcement of the windows is an important part of the reinforcement of the entire house.

Construction process

First, prepare the steel bracket; secondly, every 20 cm on the upper beam of the window, the hollow with a height of 180 cm and a width of 80 cm is drawn, because the size of the steel bracket is 50 cm in length and 80 cm in width. The height is 180 cm; then the steel bracket is placed in the hollow of the wall. Since the steel bracket is hollow, the steel bar is placed next, and the template can be used to pour the lintel of the window. The next step is the pouring window. The concrete of the frame is the way to reinforce the window.

The internship time has passed very quickly. In a blink of an eye, I have learned a lot of knowledge in this internship. I have gained a lot from it and I have a lot of experience in the internship.

First of all, I know that we can't be too single when we study. We can't just stay in the construction of the building. We should learn as much as possible. For example, this internship in the old house reinforcement project allowed me to learn a different knowledge. I have a preliminary understanding of this knowledge and made me In the future, the work in this area will not be very strange. The construction of a brick-concrete structure and the reinforcement of an old house are two different construction techniques. At first I thought it was very simple, not a brick-concrete structure. When I was actually intern, I realized that it was not what I imagined. There are a lot of knowledge and details that we have not seen before, and we need to learn and master. This internship filled my gap in this area. I will remember this internship. There are still many things we have to learn. We don’t want to learn more. We have to study hard, and our knowledge is more fulfilling. The work laid a solid foundation.

Secondly, I have gained a lot in organizational management. My previous internships were only involved in construction, and I have never participated in the organization and management. This internship is a construction technician in the project department. Therefore, my position in construction is very important. Only the weekly routines are in the project department. I and the project manager, both of us to participate, I will provide technical guidance and organize management of the construction team on the construction site. In the construction organization management, I didn't know how to manage the construction at the beginning. Although the course was opened in the school, there was a problem after entering the construction site. A series of construction organizations did not understand much. For example, at the beginning, I didn't understand its process. Under the guidance of the master, through the familiarity and understanding of the construction organization design, I learned that its rules are gradual interlocking. In order to hold this rule, I seriously I participated in every construction organization instruction issued by the project department, and drafted the construction instructions. After personal practice, this rule was quickly mastered by me, but in this internship, I did not recommend the construction organization instructions. Adopted by the construction team, they said that my instructions suggest that in terms of the completion efficiency of the project schedule and the quality of the project, only the quality is neglected, the construction progress is neglected, the progress and quality of the project must go hand in hand, and the exercise and learning should be strengthened. The ability in this area needs to be improved. After this internship, I have a good grasp of the construction organization management, which laid a solid foundation for my future internship and work to participate in organizational management.

In addition, I also learned how to fill in the information. In the process of helping the data clerk to do the materials, I learned how to do the information, when to do what kind of information, and who needs to sign. This internship taught me how to do the materials. I found that it is not easy to do the materials. These are things I have not touched before.

The month I was intern at the construction site, the one that touched me the most was safety. As a member of the project department at the construction site, you must play a good leading role, because the safety of the construction site is very important. During the internship, we often conduct safety education for workers. I have summarized some safety issues at the construction site: First, I must protect my head when I enter the construction site, that is, I must wear a safety helmet. Second, I must protect my feet because it is easy to step on the nails on the construction site. Third, outside. When walking on scaffolding, be sure not to step on the air. Sometimes the wire does not fix the bamboo piece, it is easy to cross off. This is also the worker who often arranges to work on the outer scaffold. Fourth, pay attention to the falling objects, especially When the same vertical surface is working, this is also mentioned in safety education many times, and must be paid attention to by workers. Fifth, it is safe use of electricity in the construction site. At the construction site, we must pay attention to safe use of electricity. The three-phase and two-phase lines are wrong, and there is no need to mess with and mess with the wires. The electric gates outside must pay attention to installing electric boxes to prevent rain from dripping onto the wires. Sixth, the site must be in a dangerous place. Place a signboard. Many sites are not going to take it seriously in order to save money. In fact, this is also very important, because the residents around the site cannot be ignored.

We are about to graduate. This is our graduation internship. Our last internship. We have had many internships before. In fact, I think that internship is a good opportunity for us. I think that I am studying in school. Knowledge has not yet risen to practice. For a professional with high technical requirements, internship is a process to test the level of learning. In the internship, we can find many problems. Through the process of finding problems and solving problems, it is a good learning process, so that we can learn more knowledge and deepen the mastery of knowledge. However, our graduation internship time is too short. I hope that the school will be able to lengthen the time for our professional graduation internship in the future.

Part 2: Construction Construction Internship Report

Internship is a very strange word for me, because I have not experienced an internship in my student life for more than ten years. This is my first internship. He will comprehensively test my ability in all aspects: study, psychology, body, mind, etc. . Just like a touchstone, test whether I can use the theoretical knowledge I have learned in practice. It is related to whether I can successfully settle in this challenging society in the future.

Because of the short time, I was exposed to these things in those few weeks, but I am content.

If you don't practice a lot of problems, you don't think about it. After you practice, you know what you can encounter. This requires us to have rich practical experience. The practical experience of interns like the one who has just left the school is not very rich, but the theoretical stuff. If there is nothing, then it will not be able to eat during the internship. After a period of internship at the construction site, I realized that it was not the textbook middle school that couldn’t be used, but whether you would use it or not, and you couldn’t understand the changes and the opposites.

Internship content:

At first, the prototype of this site had not yet been seen, only a foundation pit was seen. We are assigned to the release group, which is the foundation of the building and is necessary for our beginners. During this period, I had a better understanding of the level and the theodolite, and I was more familiar with the operation of the measuring instrument. I also practiced the observation of the instrument on the construction site, which enabled me to adapt to operating the instrument under different conditions.

Night shift is a skill that allows us to adapt to the field operation under more severe conditions. To adapt to the worst environment, we can train ourselves better and let us learn more and more solid. Now the night in the north is cold. In the sleepy and cold, we must complete the measurement task. This is a challenge for our college students who are just internships, and a test that reflects our ability to adapt.

As we work with the measurement, we also need to do something else to enrich our internship life. Digging, digging stones, moving bricks... is the exercise of our will. Although we have not done well for these exercises, we have also honed us at the same time. However, we have experienced the taste of society and let us know the hard work of the work. We must adapt to the work of the site.

A month's time has passed, and the life of one month has finally been fulfilled. I have done it too. The experience is also slowly experienced. I believe that there will be more exciting life in the future. I am looking forward to it.

Internship experience and gains:

The biggest gain of this internship is to learn to adapt to the environment. Through this internship, I adapted to this kind of site life. Although it is not necessary to go to work on the construction site in the future, but with this period of exercise, no matter what work is done in the future, there is a kind of perseverance that bears hardship and endurance, and also learns to adapt to the environment. In addition, I knew some problems on the construction site that were different from the school. I knew on the construction site how to be a technician and how to communicate with the workers.

Through this internship, I have gained a deeper understanding of the relevant knowledge of architecture. It should be said that learning more professional knowledge at school is only theoretical, and it is still somewhat different from reality. This internship has a certain amount of help for my ability to understand pictures. I know where to pay attention and carefully calculate when I map. Where the structure must consider the safety of the construction, and where to consider the actual construction problems when the line is released. It can meet the requirements of the specification and meet the requirements of the specification to achieve standardization of design and construction. Without this internship, perhaps only using the theoretical knowledge in books, not considering too many problems, it is even more impossible to think of whether the drawings I saw can be constructed. Although the construction site is bitter, what can be learned is some practical things. The exercise is the practical ability to solve problems.

After a month of internship, it is necessary to sum up. First of all, through this month's internship, through practice, I have learned a lot of practical knowledge. The so-called practice is the only criterion for testing the truth. Through personal experience, I have observed the construction process of the whole building at a close distance, and learned a lot of practical construction knowledge. This knowledge is often my little contact in school, and I pay little attention to it. But it is a very basic knowledge.

University life is a day of intense and full of expectation. When you are studying leisurely, you always carry your bags, stay away from family, friends, and teachers, and go to the road of your own. However, when we finally can leave the nests of the elders like the eagle feathers that have just been feathered, and walk alone on the big stage of social work, we find that the road to life is so rough and bumpy, anyone’s success is It was a storm. In just one month of internship life, I learned a lot of things that will help me a lot in my future work. This is the first time in my life that I have entered the society and I am going to work for the first time. I feel that life is really It's not easy.

The internship is essentially a simulation exercise before graduation. It is very important to be on the way to work in the society and to set foot on the job. I hope that life can be extended from this, and that what I have learned is really useful.

To sum up a sentence: Eat hard and bitter, and be a person.

Part 3: Construction internship report

In order to consolidate the theoretical knowledge learned, strengthen our hands-on operation ability and intuitive understanding of the construction phenomenon, the college arranged a one-week comprehensive teaching internship for us. This internship is based on the construction project cost training program. The arrangement of the "three-fold teaching" theoretical image of "engineering structure design principle, construction technology heavy process, engineering measurement heavy rules" is intuitive. Through visiting the construction site, watching the construction process video and other processes, understand the construction process of the construction project, and understand the building construction on the spot, laying the foundation for us to learn the construction engineering cost expertise in the future.

Monday is the first day of our internship. On this sunny morning, we came to the 203 classroom of Gongjing Building with excitement and curiosity to wait for the leadership and teacher's internship mobilization meeting. At 8:30, the moment finally arrived. We were excited to listen to the speeches of the dean and the teacher. The teacher first sent us an internship guide book, let us browse it first, and then the dean talked about the internship content and requirements. The main content is to visit the construction site of the new campus faculty dormitory building and visit the new campus of the college. The new general appearance, visit the information training building, visit the administrative office building, watch the construction project construction video and animation, and also talk about some requirements. We are required to write and describe the name, structure, construction process and adoption of the project in the diary format. The questions raised by the rules and guidelines for building materials and major engineering measurements, and finally an internship summary of no less than 3,000 words. The teacher also talked about some precautions. We asked our internships to go to the safety helmets, pay attention to safety, strictly abide by the guidance of the teachers of the team, and do not act or leave the team without authorization. Each site must make a good record of visits, and each group must be guaranteed. The original records are clear and tidy, and the tape measure that you receive should be taken care of and returned in time. Pay attention to ensuring the safety of equipment and life. Each team leader must take responsibility. He also talked about when to pay the summary, and finally he wished our training a complete success. Then the applause sounded and the mobilization meeting was over, so we led the hard hat and the school training card back to the bedroom to prepare for the internship in the afternoon. In short, this mobilization meeting will inspire everyone, and I can’t wait to go to the construction site and touch it.

The training in the afternoon began. At half past two, we gathered in front of the Gongjing Building. Teacher Zhou Jinju and Mr. Hu Zhixing led us to visit the faculty dormitory building. On the way to go, the workers are paving the sidewalk and the road has been repaired. While walking, we listened to Mr. Hu explaining how to repair the road, repair the road, and watch the slopes, drains and gullies next to the road. After not taking a long time, we saw the construction gate and then went in. The teacher told us to put the team in it and set it up well. We welcome the CEO of the construction team to give us a speech. The CEO told us that we must pay attention to safety. Listen to the command, follow the rules inside, and care for the materials and tools inside. If you don't understand anything, ask the construction worker. Going inside, I saw a lot of building materials, such as round steel, wooden formwork, stirrups, and threaded bars. On the fence, there is a plane construction drawing of the faculty dormitory, which is marked with 1, 2, and 3 buildings, and a tower crane is placed next to each other. In the construction site, the foundation is found to be the foundation of the raft. The teacher next to Hu is explaining the foundation. The foundation of the high-rise building is mostly the shape of the dome and the box, because this foundation can improve the integrity and can bear larger loads. . Since the basement is now under construction, the wall is a shear wall with dense steel bars on it, and the steel bars of the columns and beams are tied together, and no concrete has been poured. There are many conduits, drains, water pipes and drains under the base plate reinforcement. These pipes are UPVC and PVC-C plastic pipes. At first I didn't understand the role of a hole in the outside, so I asked Mr. Hu, he patiently explained it to me, told me that it was a catch, and then pointed to the flow of the gutter to show me, let me It was really a catch, and it was very easy to understand the problem, so we didn't know how to ask. I found that the reinforcement of the wall is connected by a lap joint, and the connection of the column and the beam is welded, which enhances its strength and linearity. The stressed steel bars and stirrups are fixed by wire binding. The outer periphery of the foundation is covered with concrete to protect the slope, which can prevent the slope from landslide and landslide and enhance the resistance to the soil. Time can pass very fast. I didn’t visit for a long time to go to school. I also visited the scene very much. So the teacher told us to go home and the visit ended. The first day made me gain a lot, I saw a lot of construction techniques on the construction site, I am so happy!

On the second day of the internship, the teacher gave us some videos about the building, let us know more about the internal practices of the building. The first scene of the video is the relationship between the steel and concrete that we put, the concrete and the steel have a reliable bond, which can be firmly bonded into the whole, so that the steel and concrete form a solid whole and resist together. The effect of external force; the deformation of steel and concrete after stress is consistent, and there will be no relative slip due to uncoordinated deformation of force, thus destroying the integrity of steel and concrete; the temperature deformation values ​​of steel and concrete are basically the same, not due to heat The expansion and contraction phenomenon causes the two to produce relative displacement and damage; the concrete is wrapped around the steel bar, which can effectively protect the steel bar from corrosion and make the reinforced concrete members durable. The above is also the reason why steel and concrete can be together. After reading this scene, the configuration of the steel bars is placed, mainly introducing the steel bars in the beams, slabs, columns and walls, and distributing the ribs, structural ribs, erecting ribs, stirrups, lacing and negative reinforcement on the beams and columns. The ribs and the distribution ribs are distributed in the plates and walls. Then I looked at the classification, inspection, connection, and storage of steel bars. The connection of the steel bars is welded and mechanically connected. Welding with electroslag pressure welding, wire flash welding, preheat flash welding, flash-preheating-flash welding, electric resistance welding, arc welding. There are bindings and sleeves for the mechanical connection. Then I saw the construction process of straightening, derusting, cutting and bending forming of steel bars. The cold working of steel bars was cold drawn and cold drawn, and most of the steel bars were cold drawn. Then the concrete is played. The concrete is composed of cement, gravel or pebbles, sand, water and admixture. It introduces the manufacturing process of concrete, how to vibrate concrete, and the compounding, conveying and curing of concrete. Finally, the construction technology of the cast-in-place board and the construction technology of the prefabricated board are introduced. Unconsciously, it’s time to go to school, the video is almost the same, and then walk out of the classroom with a happy mood, because these videos let me review what I have learned before, and I have seen what I have not learned. Eyes are full of happiness, a lot of gains!

The weather on Wednesday was very good and the sun was shining! At 8:30 in the morning, we gathered in front of the Gongjing Building, listened to the tasks assigned by the teacher, and then began to implement these tasks. Our group decided to measure its area first, so we measured the size around it. Since this is an irregular figure, I want to measure it. It is not so smooth. After several twists and turns, I finally measured its area. The area of ​​the Gongyi Building is about 1,400 square meters. After measuring the area, we went inside to visit the components and found that the structure of the Gongyi Building is a frame structure with 5 floors and a height of 4 meters. There is no underground garage. Then we measure the size of the door and window openings. The size of the door is 900*2100, 4050*2000, 3600*2200, 5350*2200. The size of the window is 1800*2400, 2400*2700, 900*900, 1500*900. Most of the doors found here are fire doors and glass doors. The doors are opened, pushed, and springed. The opening of the windows is fixed, flat, suspended, and pushed and pulled. They are made of aluminum alloy and glass. Then measured the stairs and measured the step height to 150mm, stepping level

The width is 300mm, the horizontal length is 2050mm, the rest platform is 4000*2000mm, and there is anti-slip treatment. The groove with a width of 20mm is cut at the front of the step. The weight of the stairs is a slab staircase. The size of the ladder is 150mm. The railing is made of steel. The side of the stairs is the same as the bottom plate. Then measured the size of the floor tile is 240*60mm, the size of the tile on the wall is 330*250mm, the size of the outer tile is 240*60mm, and the width of the corridor is 2600mm. I saw the water supply and drainage engineering and electrical engineering of this building. There are also complete fire protection facilities. Most of the pipes are UPVC and PVC-C plastic pipes, except the fire pipes are made of steel. After visiting the structure inside, the outside came to the roof and found that the above is waterproof with asphalt. The drainage of the roof is the drainage inside the eaves. The drainage pipe is made of UPVC plastic pipe. The roof also has a snorkel and a snorkel. There is also a vent cap. There is a 1% slope for drainage and a section of the daughter's wall. After visiting the roof for a while and going to school, we left and went back. I think the harvest is good today. Let me personally touch the appearance of the Jingjing Building and understand its size and specific details.

On the morning of Thursday, we gathered again and went to the administrative building of the school under the leadership of the teacher. Because there are too many people, they will bother the leadership office, so they visited the perimeter of the administrative building and the underground garage. An awning was found outside, consisting of a slab and a cantilever beam. There are flat glass doors, there are casement windows, push-pull, hanging windows, and the drainage method is internal drainage. In the underground garage, its structure is frame structure. The drain pipe and fire pipe are distributed underneath. In addition to the fire hydrant system, there are automatic sprinkler systems. There are 7 fire hydrants and 12 fire extinguishers. We measured the distance between the columns is 8100mm, the size of the main beam is 800*200, 600*200, the secondary beam is 300*200, and the expansion joint of the main building and the podium is 30mm wide, at the junction of the two floors. The floor is a well type slab. I didn't go inside to visit, so I didn't take long to read the administrative building, and then I went to other places to look at it. There are not many places to visit this day, but the places to visit are not found anywhere else, so there are also gains.

The day of Friday is the last day of the internship. The task is to write a summary, and write down your own harvest, see, hear, and learn this week.

"Do not experience the wind and rain, how to see the rainbow." Forging the self is the path that everyone must pass. By reflecting on the problem, I deeply realize that the most difficult thing for a person to win is actually oneself. Our actions are sometimes between the flashes of thought, and the left and right are the mentality. Or choose to stagnate and stagnate in yourself. If you choose the former, you will be full of vigor and enthusiasm; if you choose the latter, you will be dead and weak. If you lack enthusiasm in your work, you will lose your fighting spirit, and you will have no motivation to move forward, even passing the opportunity, because the opportunity will only be reserved for those who are prepared.

Through a week of internships, through practice, I learned a lot of practical knowledge. The so-called practice is the only criterion for testing truth. Through the side station, I have observed the construction process of the house at a close distance, and learned a lot of specific construction knowledge that is very applicable. This knowledge is often my little contact in school, and I pay little attention to it. But it is a very basic knowledge.

Therefore, this training really made us really understand the hardships of the work, but each staff member is so passionate and full of love for work, which also motivates us to work hard to put our expertise in school days. Learn well, treat each internship as a job, and be able to show yourself better in the future.
