Summary of the construction internship report

Summary of the construction internship report

As a college student who is about to graduate, social practice is an important part of our university life. During my junior summer vacation, I was fortunate enough to go to the Wanxing architectural design internship. During the nearly one month of internship, I first got into contact with some of the architectural design, and I was familiar with the architectural plane, elevation, section, and accumulated some social experience. Responsible for guiding me is a building structure engineer named Wang. The internship content is mainly the application of AUTO CAD. Under the careful guidance of Wang Gong, I soon became familiar with the various commands of CAD and made my foundation stronger. The technology is more comprehensive and the actual operation ability has been improved. The following are some of my internship processes and experiences.

On September 11, the first day of the internship, I was assigned to a large office of the design company with a separate desk and computer. But I don't know what to do, I can't insert anything, just look here, go shopping there, and finally the engineer in the company gave me a way. He told me some simple requirements for me to draw with CAD software. The plan and elevation of a two-story office building finally got something done, so I started to figure it out. To be honest, I used to draw pictures when I was at school. The speed and quality were relatively high, but when I finished it at a very fast speed, Wang Gong pointed out a lot of normative deficiencies, and then he patiently told I designed the process and design specifications for different building types. First of all, it is an understanding of the entire process of the building. The formation and process of the building are as follows: Investor investment--national review and approval--design institute to make architectural plan--winning bid--design institute to carry out architectural design--construction department approval--construction unit construction--supervisor review --Construction completed, delivery - decoration company to carry out renovation - delivery - by investors and real estate companies to buy and sell. Throughout the process, the design part of the building occupies a very important position. Therefore, every step of design should be in accordance with the regulations, and every step should be cautious. There are also processes in the design: do the plan - the plane design - the facade, the section design - hydropower, heating, elevator design.

After a general understanding of these aspects, we did the actual operation - drawing. The program used for drawing is AUTO CAD--computer-aided design. The program has two-dimensional, three-dimensional drawing capabilities. The work I did was a two-dimensional drawing of the building's flat, vertical, and sectioned sections. To draw, you must first understand the function, and then familiarize yourself with the usage of each tool. There are also steps when drawing: axis--wall line--doors and windows--stairs--in-house layout--marking. Also modify while drawing. I just started to draw some simple floor plans and learn to use shortcut keys to make drawings. In the process of drawing, I also encountered some difficulties, such as the intersection of arc and line, the closing of the figure, the drawing of the stairs, and often made mistakes during these times, affecting the next operation. In these operations, you need to be careful and patience to modify.

In the process of learning, the master and colleagues have given me great help, taught me how to use shortcut keys, if you use a few tips in the process of drawing, you can really achieve twice the result with half the effort, let me take less in learning. detour.

Experience:

The first time I went to the company for an internship, when I first came, I was very mentally ill and didn't know how to get along with others. After a few days of internship, I found that it is not difficult to get along with my colleagues. When you encounter a place you don't understand, you have to ask more. When you ask, you will increase your chances of communicating with your colleagues. In this way, not only the problem will be solved, but also the group will be quickly incorporated. Here, we must study hard and ask questions, communicate with others, and treat people with sincerity.

This summer internship brought me more than just a social experience, but also a fortune in my life. What is more gratifying is that I also met some good friends during the internship, and they gave me a lot of help. As the saying goes: I don’t know how to apply the theory to practice. Today’s university education is based on theory. It is a great benefit for me to have the opportunity to enter the design company. I will be quick. I graduated to the society, I believe this internship will help me to work in the future.

Through this internship, I feel that I have gained something in design. The internship is mainly for the purpose of promoting our future work and business improvement, enhancing our future competitiveness and adding a cornerstone to our future foothold. The Wang Gong of the internship unit also gave me a lot of opportunities to participate in their design. I have learned a lot of problems that were difficult to solve before and the problems that I will face in design work in the future. This internship has enriched my knowledge in this area and made me move to a deeper level. It has a certain role in promoting my future in the society, but I also realize that I want to do this work alone. These days' internships are not acceptable. I also need to accumulate little by little in my usual study and work, and continue to enrich my experience. The road ahead of me is still very long, and I need constant efforts and struggle to really go well. I firmly believe that through this internship, I have gained practical experience for my lifelong experience.

After the actual work will be continuously verified, I will continue to understand and appreciate the knowledge I have learned in the internship. In the future work, I will continue to apply the theoretical knowledge and practical experience I have learned to practical work. Come, fully demonstrate the personal and life value of the self. To achieve self-ideal and bright future efforts.

The internship report you are looking at is: a summary of the construction internship. Large values ​​have the risk of causing cracks, but if the surface is covered with a light insulation material, such as foam sponge, in time to remove the template, it has a significant effect on preventing excessive tensile stress on the concrete surface. Reinforcement has little effect on the temperature stress of mass concrete because the mass ratio of mass concrete is extremely low. It only has an effect on general reinforced concrete. Under the condition that the temperature is not too high and the stress is lower than the yield limit, the properties of the steel are stable regardless of the stress state, time and temperature. The linear expansion coefficient of steel differs greatly from the coefficient of linear expansion of concrete, and only a small internal stress occurs between the two when the temperature changes. Since the elastic modulus of steel is 7 to 15 times that of concrete, when the internal concrete stress reaches the tensile strength and cracks, the stress of the steel will not exceed 100~200kg/cm2. Therefore, it is intended to be utilized in concrete. Reinforcing bars to prevent the appearance of small cracks is difficult. However, the cracks in the structure after reinforcement generally become a large number, a small pitch, and a small width and depth. Moreover, if the diameter of the steel bars is fine and the spacing is dense, the effect of improving the crack resistance of the concrete is better. Fine and shallow cracks often occur on the surfaces of concrete and reinforced concrete structures, most of which are dry shrinkage cracks. Although the crack is generally shallow, it still has a certain influence on the strength and durability of the structure. In order to ensure the quality of concrete works, prevent cracking, and improve the durability of concrete, the correct use of admixtures is also one of the measures to reduce cracking. For example, using water-reducing and anti-cracking agents, the author summarizes its main functions in practice:

There are a large number of capillary channels in the concrete. After the water evaporates, capillary tension is generated in the capillary, which causes the concrete to shrink and deform. Increasing the capillary diameter reduces the capillary surface tension, but reduces the strength of the concrete. This theory of surface tension has been internationally recognized as early as the 1960s.

The water-cement ratio is an important factor affecting the shrinkage of concrete. The use of water-reducing and anti-cracking agents can reduce the water consumption of concrete by 25%.

The amount of cement is also an important factor in the shrinkage of concrete. Concrete with water and crack inhibitor can reduce the amount of cement by 15% under the condition of maintaining concrete strength. The volume is supplemented by increasing the amount of aggregate.

The water-reducing and anti-cracking agent can improve the consistency of the cement slurry, reduce the bleeding of the concrete, and reduce the shrinkage deformation.

Improve the adhesion of cement slurry and aggregate, and improve the crack resistance of concrete.

Concrete is constrained to produce tensile stress when contracted, and cracks are generated when tensile stress is greater than concrete tensile strength. The water-reducing and anti-cracking agent can effectively improve the tensile strength of the concrete and greatly improve the crack resistance of the concrete.

Adding admixture can make concrete compact, can effectively improve the carbonation resistance of concrete and reduce carbonization shrinkage.

After the water-reducing and anti-cracking agent is added, the concrete retardation time is appropriate, which is effective in preventing the rapid hydration and heat release of cement.

In order to avoid the increase of plastic shrinkage caused by long-term non-condensation of cement.

Concrete with admixture is easy to work with, the surface is easy to level, forming microfilm, reducing water evaporation and reducing drying shrinkage. Many admixtures have the functions of retarding, increasing workability and improving plasticity. We should be in engineering practice. More experimental comparisons and research in this area may be more simple and economical than simply improving external conditions.

4 The early curing practice of concrete proved that most of the common cracks in concrete are surface cracks of different depths. The main reason is that the temperature gradient causes the temperature in the cold area to drop sharply and is easy to form cracks. Therefore, the insulation of concrete is especially important to prevent early cracks on the surface. From the viewpoint of temperature stress, the insulation should meet the following requirements:

1) Prevent the temperature difference between the inside and outside of the concrete and the gradient of the concrete surface to prevent surface cracks.

2) To prevent the concrete from being too cold, try to make the minimum temperature during the construction period of the concrete not lower than the stable temperature of the concrete use period.

3) Prevent old concrete from being too cold to reduce the constraints between old and new concrete. The main purpose of early curing of concrete is to maintain suitable temperature and humidity conditions to achieve two effects. On the one hand, the concrete is protected from unfavorable temperature and humidity deformation, and harmful cold shrinkage and shrinkage are prevented. One party

The surface makes the cement hydration smooth, in order to achieve the design strength and crack resistance. Suitable temperature and humidity conditions are interrelated. Insulation measures on coagulation often have a moisturizing effect. Theoretically, the water content in the newly poured concrete can fully meet the requirements of cement hydration. However, due to evaporation and other reasons often cause water loss, thereby delaying or hindering the hydration of cement, surface concrete is the easiest and directly affected by this adverse effect. Therefore, the first few days after concrete pouring is a critical period of maintenance, and should be paid attention to during construction.

Therefore, we must be cautious in handling these events during construction, depending on the situation.

These problems are all noticed in the construction work. What kind of cement is used in the construction, the amount should be paid attention to, and the early maintenance of the concrete.

There are also template designs:

Construction preparation 1) Discharge: firstly measure the side column of the building, the axis of the wall, and draw the axis from the axis. When the template is laid, the center line and the edge line of the template are ejected by the ink line according to the construction drawing. The wall template should eject the edge line and the outer control line of the template to facilitate template installation and correction.

2) The level of the building level is directly measured to the template installation position according to the requirements of the actual elevation.

3) The bottom position of the template pad should be leveled in advance, and the debris should be cleaned to ensure the correct position of the template, preventing the bottom of the template from leaking or the roots after the concrete is formed.

4) The foreman determines the assembly design plan of the template in advance, and carries out the technical, quality and safety of the construction team.

5) The template should be brushed with a release agent. There are a lot of things to note, I won't list them here.

I firmly believe that through this period of internship, the practical experience I have gained will benefit my life. I will continue to be verified in my actual work after graduation. I will continue to understand and understand the knowledge I have learned in the internship in the future. In my work, I will continue to apply the theoretical knowledge and practical experience I have learned to practical work, fully demonstrating my personal and life values. To achieve self-ideal and bright future efforts.

Summary of the construction internship report

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.

Summary of the 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.
