Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to a prefabricated mortise and tenon joint steel pipe bundle composite shear wall and its processing and assembly method. Background Technology

[0002] Shear walls are important lateral force resisting components in building structures and play a crucial role in seismic resistance. However, current connection methods between steel tubes in steel tube bundle composite shear wall structures are mainly welding and bolting. Welding has the following disadvantages when applied to steel tube bundle composite shear wall structures:

[0003] 1. Welding pollutes the environment, and manual welding requires highly skilled workers;

[0004] 2. Cracks are prone to occur at the connection points. The connection between the steel pipe bundle and the beam-column is subjected to large shear forces, and some measures need to be taken to strengthen it.

[0005] 3. Stress concentration can occur at the welded joints of steel pipes, which can affect the structural bearing capacity;

[0006] 4. Assembling steel pipe bundles into a single wall increases the difficulty of transportation and hoisting;

[0007] 5. Bending at the connection point between the steel pipe bundle and the beam / column may cause twisting deformation at the connection point, affecting the overall performance of the structure.

[0008] Meanwhile, bolted connections have the following disadvantages when used in steel tube bundle composite shear wall structures:

[0009] 1. High installation difficulty: The bolt connection of steel pipe bundle shear wall requires high-precision technology and professional equipment, making the installation difficult;

[0010] 2. Decreased durability: Due to the gaps in the bolted connections, they are easily affected by external factors (such as water, moisture, etc.), leading to corrosion and deformation, thereby reducing the durability of the steel pipe bundle shear wall;

[0011] 3. High construction cost: The bolted connection of the steel pipe bundle shear wall requires a large number of bolts and connectors, which increases the construction cost;

[0012] 4. High maintenance difficulty: If the bolt connections are damaged or loose, the entire wall needs to be dismantled and reinstalled, which makes maintenance difficult. Summary of the Invention

[0054] In a further optimized design, the first horizontal hole 11, the second horizontal hole 12, and the third horizontal hole 13 are coaxially arranged; the first vertical hole 8 and the third vertical hole 10 are coaxially arranged; and the second vertical hole 9 and the fourth vertical hole are coaxially arranged. A first steel strand is installed in each of the first horizontal hole 11, the second horizontal hole 12, and the third horizontal hole 13; a second steel strand is installed in the first vertical hole 8 and the third vertical hole 10; and a third steel strand is installed in the second vertical hole 9 and the fourth vertical hole.

Positioning cylinders 16 are fixedly connected within these positioning holes, and the positioning cylinders 16 are adapted to the positioning posts 14. The positioning cylinders 16 and positioning posts 14 are detachably connected. By inserting the positioning posts 14 of the first and second positioning components into the corresponding positioning cylinders 16, the first square steel pipe 1, the second square steel pipe 2, and the third-party steel pipe 3 can be accurately positioned during splicing, preventing arbitrary movement. Simultaneously, the holes on the same center line can be accurately aligned, facilitating the operation of the steel strands.

[0057] This invention also provides a processing and assembly method for a prefabricated mortise and tenon joint steel pipe bundle composite shear wall, comprising the following steps:

[0058] S1. Prefabricate the first square steel pipe 1, the second square steel pipe 2, and the third square steel pipe 3 in the factory according to requirements; prefabricate several first mortise ends 5 on the side of the first square steel pipe 1 near the third square steel pipe 3, and prefabricate several second tenon ends 6 on the side of the third square steel pipe 3 near the first square steel pipe 1. The first mortise ends 5 and the second tenon ends 6 are adapted to each other so that the first mortise ends 5 and the second tenon ends 6 can be detachably connected. Prefabricate several second mortise ends 7 on the side of the third square steel pipe 3 near the second square steel pipe 2, and prefabricate several first tenon ends 4 on the side of the second square steel pipe 2 near the third square steel pipe 3. The second mortise ends 7 and the first tenon ends 4 are adapted to each other so that the second mortise ends 7 and the first tenon ends 4 can be detachably connected, so that the first square steel pipe 1, the second square steel pipe 2, and the third square steel pipe 3 can all be spliced ​​together by mortise and tenon joints.

[0059] Several first vertical holes 8 are provided at the top and bottom of the first tenon end 5, and several third vertical holes 10 are provided on the top surface of the second tenon end 6. The third vertical holes 10 are coaxially arranged with the first vertical holes 8.

[0060] Several fourth vertical holes are provided on the top surface of the first tenon end 4, and several second vertical holes 9 are provided on the top and bottom of the second tenon end 7. The second vertical holes 9 are coaxially arranged with the fourth vertical holes.

[0061] The first tenon end 5 has several first horizontal holes 11 on its side wall, the first tenon end 4 has several second horizontal holes 12 on the center of the side near the third steel pipe 3, and the second tenon end 6 has several third horizontal holes 13 on the center of the side near the first square steel pipe 1. The first horizontal holes 11, the second horizontal holes 12, and the third horizontal holes 13 are coaxially arranged.

[0062] S2. Pre-embed steel pipes between the through holes in each square steel pipe; pre-embed steel pipes between the through holes on the same center line in each square steel pipe so that the through holes on the same center line are connected, which facilitates the later installation of steel strands, and then install the first positioning component and the second positioning component into the designated position.

[0063] S3. Pour concrete into each square steel pipe; the concrete is poured into each square steel pipe, and the square steel pipe constrains the concrete, causing the concrete to be under triaxial compression, which improves the bearing capacity of the concrete; at the same time, the concrete can also delay or prevent premature local buckling of each square steel pipe, thus improving the overall bearing capacity of the concrete in each square steel pipe.

[0064] S4. Transport each square steel pipe to the construction site for splicing; since the entire square steel pipe concrete fabrication is completed in the factory, product quality is guaranteed; at the same time, breaking down a large steel pipe bundle shear wall panel into individual square steel pipe concrete reduces the difficulty of hoisting; the individual square steel pipe concrete can be assembled on-site according to the design sequence, which has environmentally friendly and economical characteristics; install the first square steel pipe 1 in the designated position, install the second tenon end 6 of a third third steel pipe 3 into the first mortise end 5, and simultaneously position the positioning post 14 within the sleeve, move the third third steel pipe 3, and when the positioning post 14 on the third third steel pipe 3 extends into the positioning sleeve 16 on the first square steel pipe 1, the third third steel pipe 3 is installed in place, then install the second tenon end 6 of another third third steel pipe 3 into the second mortise end 7 of the previous third third steel pipe 3, and simultaneously position the positioning post 14 on this third third steel pipe 3 within the sleeve, move this third third steel pipe 3. When the positioning post 14 on the third-party steel pipe 3 extends into the positioning cylinder 16 on the previous third-party steel pipe 3, the third-party steel pipe 3 is installed in place. The remaining third-party steel pipes 3 are installed sequentially until the required number of third-party steel pipes 3 are installed. Finally, the first tenon end 4 of the second square steel pipe 2 is installed into the second mortise end 7 of the third-party steel pipe 3, while the positioning post 14 on the second square steel pipe 2 is placed in the sleeve. The second square steel pipe 2 is moved, and when the positioning post 14 on the second square steel pipe 2 extends into the positioning cylinder 16 on the third-party steel pipe 3, the second square steel pipe 2 is installed in place, completing the splicing operation. This invention, through the tenon and mortise connection method, prevents the square steel pipes from moving left and right. At the same time, the first positioning component and the second positioning component prevent the square steel pipes from moving back and forth. The first positioning component and the second positioning component also ensure that the holes on the same center line can be accurately aligned, facilitating the operation of steel strands.

[0065] S5. After splicing, steel strands are placed into each through hole. This invention connects the first square steel pipe 1, the second square steel pipe 2, and the third square steel pipe 3 into a whole through the first steel strand, connects the first square steel pipe 1 and the third square steel pipe 3 into a whole through the second steel strand, and connects the second square steel pipe 2 and the third square steel pipe 3 into a whole through the third steel strand, so that the whole cannot slide in any direction, improving the overall stability and the ability to withstand lateral forces.
