Construction Engineering Internship Report

Foreword

Production internship is an essential practical teaching link in the teaching plan of construction engineering major. It is the basis of the theoretical knowledge learned. Integration with engineering practice. During the internship process, I went deep into the construction unit as a constructor, using a high-rise residential community as the internship site. Under the guidance of the director of the technical office of the project department, I participated in surveying engineering, steel bar engineering, formwork engineering, concrete engineering, etc. Operate the entire process of masonry engineering construction, learn the construction technology and construction organization and management methods of each type of work, learn and apply relevant engineering construction specifications and quality inspection and assessment standards, and learn how to handle technology during the construction process.

IV. Basic instructions

1. The building positioning coordinates of this project and the indoor and outdoor height difference, indoor ±0.000 are equivalent to the absolute elevation of 28.300M.

2. Except for the elevation and general plane positioning dimensions in meters, all other dimensions in this construction drawing are in millimeters.

3. Unless otherwise specified, elevations in construction drawings are based on building elevations.

4. The outdoor elevation of the building in this construction drawing is the design elevation. The specific height difference between indoor and outdoor is subject to the general construction drawing. The wall exterior must be floor-to-ceiling.

This project has a barrier-free design in accordance with the specification requirements. The barrier-free design scope includes: roads in the area, residential entrances, passages, elevators and elevator halls. The barrier-free housing suites of this project have been set up in the first phase of the freshman year.

5. Specific participation in the work

1. Surveying project

Construction surveying directly serves the construction of the project, and its results are not only for construction and construction inspection It is a criterion and an important basis for verifying whether the location, elevation and interrelationship dimensions of the completed project meet the design requirements.

Floor setting:

Because the floor is high, we use a line drop and theodolite to place the floor axis. Hang from the upper layer to the lower layer, mark points on the hanging wire holes, use the theodolite to check the squareness of the points, and use the theodolite to mark the control line elastic points. The other axes use the middle cross control point as the reference axis. Measure with a steel ruler and pop with an ink line.

Then use a steel ruler to measure the dimensions of the wall according to the plan and use an ink line to stretch it.

Copy level:

1. Structure 50 line:

In order to control the thickness of poured concrete, first use a steel ruler to measure the 50 line on the outer wall of the first floor. Come up and draw on the shear wall column reinforcements, then use a level to copy 50 points onto all the shear walls, and use paint to draw a point on each shear wall.

2. Building 1-meter line

Building 1-meter line means that after the ground level is completed, the distance from the ground to the line is 1 meter. First, use a steel ruler to measure 2.800M from downstairs and draw dots on the shear wall. Because they are all shear walls, it is inconvenient to use a level to copy all the 1-meter lines. First, use a level to mark all the 1-meter lines that can be copied. Use a horizontal tube to copy all the missed points, and then use an ink line to capture them.

2. On-site inspection:

There are many problems on site that need to be counted, such as recording the places where the bulging pillars have been chiseled, checking the verticality of the masonry and the mortar of the mortar joints Fullness. The places where the tendons are too long should be recorded. Check the squareness of the gray cake. Supervise the reinforcing steel workers, carpentry supporting formwork, concrete workers pouring concrete, bricklayers building walls, nailing steel wire mesh, the squareness of ash cake, and manage civilized construction on site to ensure timely cleanup.

8. Main structure construction method

Section 1 Overall Arrangement

Chisel the base of the column→column reinforcement, column formwork→beam reinforcement, beam formwork (concrete Curing for at least 7 days) → Remove the formwork for 1-day columns and remove the formwork for beams after 7 or 28 days.

Section 2 Formwork Project

1. Overview

The formwork construction of this project mainly uses 20-thick plywood and steel-wood mixed support.

2. Beam and plate formwork

Made of plywood, itself fixed with wooden pads and steel pipe back bars.

1. Beam formwork installation:

(1) Pop up the axis, beam position and horizontal line on the column, and nail the column head formwork.

(2) Beam bottom formwork: Adjust the elevation of the pillars according to the design elevation, then install the beam bottom formwork and pull wires for leveling. When the beam bottom span is greater than or equal to 4m, the mid-span beam bottom should be arched according to the design requirements. If there is no design requirement, the arching height should be one thousandth to three thousandths of the beam span. When the primary and secondary beams are handed over, the primary beam is arched first, and then the secondary beam is arched. Cantilevered beams must be arched by 0.6% at the cantilever end.

(3) When the support top is below the floor height of 4.5m, two horizontal tie rods and scissor braces should be installed. When the floor height is above 4.5m A separate construction plan must be made.

(4) Beam side formwork; install beam side formwork, presser foot plate, diagonal brace, etc. according to the ink line. The height of the beam side formwork should be determined according to the beam height and the collision or pressure of the floor formwork.

2. Floor formwork

(1) Set up pillars and keels according to the layout of the formwork. The distance between the pillars and the keel should be determined in the formwork design based on the concrete weight of the floor slab and the size of the construction load. Generally, the pillars are 800∽1200mm, the large keel spacing is 600∽1200mm, and the small keel spacing is 400∽600mm. The arrangement of pillars should consider setting up construction channels.

(2). Adjust the height of the pillar through wires, level the large keel, and erect the small keel.

(3) When laying the template, you can start from all sides and close it in the middle. If it is pressed sideways, the corner formwork should be wired and nailed.

(4) After the floor formwork is laid, carefully check whether the brackets are firm, and the formwork beam and slab surfaces should be cleaned.

3. Beam and formwork bracket system

The first layer of brackets uses Φ48 steel pipe brackets, and the remaining floors use steel supports. The vertical pole spacing is: floor beams ≤ 800mm, Board ≤1000mm. For the large-section frame beams on the first floor, in order to ensure that no deformation occurs during concrete pouring, three rows of vertical poles are erected under the support, with the spacing between the two side poles @≤600mm and the spacing between the middle poles @≤900mm. In addition, considering Above it is a larger cross-section concrete column. To ensure quality, if the concrete strength of the beam does not reach 100% when the upper layer of concrete is poured, the lower bracket must not be removed.

5. Removal of formwork

1. Wall, column formwork and beam side formwork must be removed 48 hours after the platform and beam concrete are poured.

2. Slabs with a width of ≤2.0m must be removed when the conventional curing of the concrete test block reaches 50% of the design concrete strength standard value; slabs with a span between 2.0m~8.0m must The concrete test block can be dismantled only when the conventional curing of the concrete test block reaches 75% of the designed concrete strength standard value; the slab with a width greater than 8.0m can only be dismantled after the conventional curing of the concrete test block reaches 100% of the designed concrete strength standard value (after 28 days). ); If the beam slab concrete on the upper floor has not been constructed, support should be added after the beam slab bottom formwork of this floor is removed.

3. Beams with a span of ≤8.0m must be removed after the conventional maintenance of the concrete test block reaches 75% of the designed concrete strength standard value; beams with a span of more than 8.0m must be removed after the concrete test block is tested. The block can be dismantled only after the routine maintenance reaches 100% of the designed concrete strength standard value (after 28 days).

4. All cantilevered components must wait until the conventional curing of the concrete test block reaches 100% of the designed concrete strength standard value (28 days later) before the bottom form can be removed.

5. Structures that have had their formwork and supports removed can only bear the calculated load after the concrete reaches the design strength. It is strictly prohibited to pile excessive building materials during construction.

Section 3 Steel Bar Engineering

1. Steel Bar Binding and Installation

Before tying steel bars, carefully familiarize yourself with the drawings, check the ingredient list and drawings, and see if there are any discrepancies in the design. , carefully check whether the size and shape of the finished product are consistent with the cutting table. The binding can only be carried out after checking that everything is correct.

Use 20# iron wire to tie steel bars with diameters above 12, and 22# iron wire to tie steel bars with diameters less than 10.

1. Column

(1). The hooks of the vertical steel bars should face the center of the column. The angle between the plane of the hooks of the corner steel bars and the formwork surface. For rectangular columns, it should be 45° angle, small cross-section column, when inserting the vibrator, the angle between the hook and the template should not be less than 15 degrees.

(2). The joints of the stirrups should be staggered and placed vertically; the corners of the stirrups and the intersections of the vertical steel bars should be firmly tied (the intersections of the straight parts of the stirrups and the vertical steel bars can be placed every other The roots form a plum blossom pattern to each other and take root). When tying stirrups, the wire buckles should be tied to each other in a figure-eight shape.

(3) When tying column bars, the verticality should be controlled by hanging wires, and the spacing between main bars should be strictly controlled. The stirrups and column vertical bars at the overlap joints of the column bars should be fully tied, and the rest can be tied with plum blossom points.

(4). The vertical steel bars of the lower columns are exposed on the floor. It is advisable to use tools or column hoops to retract them into a column bar diameter to facilitate the overlap of the steel bars of the upper columns and connect them with the upper beams. During plate reinforcement welding, when the cross-sections of the upper and lower columns change, the exposed portions of the steel bars of the lower columns must be closed accurately before tying the beam steel bars.

2. Beams and slabs

(1) When the longitudinal load-bearing steel bars are arranged in double or multiple layers, short steel bars with a diameter of 25mm should be placed between the two rows of steel bars. If the diameter of the longitudinal steel bars is greater than 25 mm, the diameter specifications of the short steel bars shall be the same as the longitudinal steel bars.

(2). The stirrup joints should be arranged staggered and tied with the two erecting bars. For cantilever beams, the stirrup joints should be at the bottom. The rest of the methods are the same as for columns. The outer corners of the beam's main bars and stirrups should be fully tied, and the rest can be tied at plum blossom points.

(3) The steel mesh binding of the board is the same as that of the foundation, but attention should be paid to the negative steel bars (surface reinforcement) on the upper part of the board to prevent being stepped on; especially awnings, overhangs, balconies, and window sills For cantilever slabs, the position of the negative reinforcement must be strictly controlled, and bench iron must be added at the root and end of the board to ensure the effective height of the negative reinforcement.

(4) At the intersection of the plate, secondary beam and main beam, the steel bars of the plate are on the top, the steel bars of the secondary beams are on the middle layer, and the steel bars of the main beam are on the bottom. When there are ring beams or pad beams, the main beam The steel bars are on top.

(5). The binding joints of steel bars should comply with the following regulations:

A. The distance between the end of the overlap length and the bend of the steel bar shall not be less than 10 times the diameter of the steel bar. The joint It should not be located at the maximum bending moment of the component.

B. In the tension area, the ends of the Class I steel bar binding joints should be hooked.

C. The overlap of steel bars should be tied firmly with iron wire in the center and both ends.

D. The overlap length of the tensile steel bar binding joints should comply with the structural design requirements.

E. The thickness of the concrete protective layer of the stressed steel bars should comply with the structural design requirements.

(8) Before tying the plate bars, the wires must be stretched according to the spacing required in the design drawing, and tied according to the wires to control the quality.

Section 4 Concrete Project

This project uses commercial concrete, which is transported by concrete pumps and assisted by tower cranes.

1. Pouring of concrete:

1. The formwork should be watered and moistened before pouring, and the cleaning openings of the wall and column formwork should be closed after removing debris and accumulated water.

2. General requirements for concrete pouring

(1) When pouring concrete for vertical structures, if the pouring height exceeds 3m, string tubes, conduits, chutes or formwork should be used. There is a door opening on the side.

(2) When using a plug-in vibrator, you should insert it quickly and pull it out slowly. The insertion points should be evenly arranged, move point by point, and proceed in sequence without omissions to achieve even vibration. The moving distance is not greater than 1.5 times the radius of action of the vibrator (generally 300∽400mm). When vibrating the upper layer, 50mm should be inserted into the concrete surface of the lower layer to eliminate the joint between the two layers. The moving spacing of the flat vibrator should ensure that the flat plate of the vibrator covers the edge of the vibrated part.

(3) Concrete pouring is carried out continuously. The secondary layer of concrete is poured before the initial setting of the front layer of concrete. The maximum rest time should be determined according to all cement varieties and concrete initial setting conditions. Generally, if it exceeds 2 hours, it should be treated as a construction joint.

(4) When pouring concrete, a special person should be assigned to regularly observe whether there is any displacement, deformation or blockage of the formwork steel bars, reserved holes, embedded parts, insertion bars, etc. If any problems are found, the pouring should be stopped immediately and the Finishing before initial setting on poured concrete.

3. Concrete pouring of beams and slabs

(1) The beams and slabs of ribbed floor slabs should be poured at the same time. The pouring method should be started from one end using the "rushing method", first The beams are poured in layers into steps and then poured together with the concrete of the slab when they reach the floor level.

(2). The thickness of the virtual paving when pouring the floor slab should be slightly larger than the thickness of the slab. Use a flat vibrator to vibrate back and forth in the vertical pouring direction. Be careful to constantly check with moving signs or poles to control the thickness of the concrete slab. After vibrating, smooth the surface with a scraper or mop.

4. Concrete pouring for stairs

(1) Concrete for stair sections is poured from bottom to top. Since the stair treads use a closed formwork, there are openings on the tread surface. The base slab concrete is poured together with the step concrete and is continuously pushed upward.

(2) The stair concrete should be poured continuously.

(3). Construction joint location: Depending on the structural conditions, it can be left in the middle of the stair platform slab or within 1/3 of the stair section.

5. When pouring the beam concrete, the column joint area shall be constructed with high-strength grade concrete, and the interface is at 500 meters from the column edge.

2. Concrete maintenance

1. After the concrete is poured, it should be covered within 12 hours and watered for curing.

2. The watering and curing date of concrete shall not be less than 14 days for concrete mixed with retarding admixtures or with anti-seepage requirements. Before the concrete strength reaches 1.2MPa, no stepping on it or construction vibration is allowed. The column and wall strip molds must be cured for more than 2 days. After removing the molds, wrap them in cotton cloth and water them on the cotton cloth for curing to ensure that the surface of the facade structure remains moist.

3. The number of daily waterings should be enough to keep the concrete in a sufficiently moist state.

Section 5 Masonry Engineering

1. Materials

1. Bricks:

The variety and strength level of bricks must comply with the design requirements, and the specifications should be consistent with factory certification and test sheets;

2. Cement

The variety and label should be selected according to the location of the masonry and the environment. Generally, No. 325 ordinary Portland cement or slag Portland cement; it must have factory qualification certificate and test report before it can be used; different types of cement must not be mixed.

3. Sand:

Use medium sand. When the strength grade of prepared cement mortar or cement mixed mortar is equal to or greater than M5, the mud content of the sand shall not exceed 5%. When the mortar strength grade is less than M5, the mud content of the sand shall not exceed 10%.

4. Brick wall masonry

Construction sequence: draw the plane line → check the reserved connecting ribs on the columns and walls. The remaining ones must be completed → masonry → installation or Cast-in-situ door and window lintel → top masonry.

(1) Arrange bricks and lay down the bottom: Generally, when the first skin brick of the exterior wall is laid down, the horizontal walls should be lined with small bricks, and the front and rear longitudinal walls should be lined with straight bricks. According to the ink line at the position of the window and door opening that has been popped up, check whether the length and size of the wall between the door and window and the attached wall columns (stacks) comply with the brick arrangement mold. If they do not meet the mold, consider the plan for cutting and laying bricks. The cut bricks or tiles should be arranged in the middle of the window, next to the wall pillars (stacks) or other inconspicuous locations.

(2). Hanging wires: If the masonry is one brick thick or less, single-sided hanging wires must be used; if the masonry is one and a half bricks thick or more, double-layer hanging wires must be used. If several people are building a long wall at the same time, it is best to use one through line, and several branch points should be set up in the middle; the small lines should be tightened and straight, and each brick should be threaded and leveled to make the horizontal seams uniform and straight. smooth.

(3) Bricklaying: Bricklaying should use the squeezing method or the Sany bricklaying method. The operation essentials of the Sanyi bricklaying method are to shovel ash, squeeze a brick, and scrape off the squeezed mortar. During operation, the bricks should be placed flat and aligned with the line. During the masonry operation, the joints and random joints are controlled in sections. Carry out self-inspection frequently. If any deviation is found, it should be corrected at any time. It is strictly forbidden to correct it by hitting bricks afterwards. The overflowing ash stains on the brick wall should be scraped off as they are laid. It is strictly forbidden to leave straight rubs at the corners of internal and external walls. For other temporary interruptions, the method of leaving rubs must comply with the provisions of the construction specifications.

9. Problems in the internship:

Without practice, many problems will not be considered. After practice, we will know that we may encounter any situation, which requires us to have rich experience. Practical experience, for example, interns who have just stepped out of school still have very little practical experience, but if they don’t know anything about theory, they will not be able to learn anything during the internship. After a period of internship at the construction site, I realized that it is not that things learned in textbooks cannot be used, but it depends on whether you can use them and whether you know how to adapt and draw inferences. The more serious problems in this internship are as follows:

Problem 1: Insufficient grasp of theoretical knowledge, such as: the curing time of concrete and mortar test blocks, and what should be vibrated when making test blocks degree, the curing temperature and curing time after the concrete is poured, and the reason for cracks in the concrete cannot be analyzed, etc. These concepts are very vague. It was only after I used them in practice that I realized that I had not studied well. When I was in school, it was just to cope with the exam and pass the test. I just reported the key points taught by the teacher a few days before the exam and memorized them several times. Once the exam was over, There is a blank in my mind, no matter whether I use it in the future or not, it has disappeared from my memory. When you need it, you will realize that you have not remembered these. Just like no one will ask you these when entering the construction site now, but as a technician, you don’t know how to maintain the test block, what is the cause of cracks in concrete, and a series of other questions , how can you guide the construction?

The solution to this problem is to have a solid grasp of it in future studies, not to memorize it by rote, but to apply it flexibly and integrate it with practice.

Problem 2: The ability to be familiar with drawings is poor, and I cannot imagine the three-dimensional appearance of flat graphics. As a result, it is impossible to clearly judge whether the construction is right or wrong.

Problem 3: I don’t know the latest construction specifications, so I can’t quickly judge whether the construction is right or wrong.

Question 4: Some construction sequences are not clear yet, and the operation of each construction process is not understood.

Problem 5: Poor ability to connect theory with practice. I know too little about some new developments in architecture.

Question 6: The actual building elevation and structural elevation are easily confused when calculating the construction elevation. It is especially easy to make mistakes when using the 50th line to control the height of walls and door and window openings. It is not clear when to include Ground practices, when not included.

10. Experience and gains from the internship:

First of all, the biggest gain from this internship is that I learned to adapt to the environment. Before I went to the construction site, I never imagined that I would be able to endure the two-month internship. But through this internship, I adapted to this kind of construction site life. Although I may not necessarily work on a construction site in the future, after this period of training, I will have a hard-working perseverance no matter what kind of work I do in the future, and I will also learn to adapt to the environment. In addition, I learned about some issues that are different from those in school at the construction site, that is, I learned how to communicate with workers as a technician at the construction site.

Secondly, through this internship, I have a deeper understanding of the relevant knowledge of engineering. It should be said that no matter how much professional knowledge you learn in school, it is only theoretical and is still somewhat different from reality. This internship has helped my drawing and drawing abilities to a certain extent. When reading pictures, I know where to pay attention and calculate carefully. Where on the structure should we consider safety issues during construction, and where should we consider actual construction issues when drawing. It can be constructed upon arrival and meets the specification requirements, achieving standardization of design and construction. Without this internship, I might have just copied the drawings from the book, and would not have considered too many issues, let alone whether my design can be constructed.

Although the construction site is hard, you can learn some practical things and exercise your practical ability to solve problems. For example: the wall will also shift, the height of the stairwell is not enough when setting up the stair formwork, there will be slight changes in the size and elevation of the balcony and bay windows, and many other problems that may occur during the project. Only through practice can we find the cause of the problem and find a solution. This internship laid the foundation for me to work in the future.
