Description

Technical Field

[0001] This application relates to the field of shear wall construction technology, and in particular to a prefabricated seismic-resistant shear wall. Background Technology

[0002] Shear walls are primarily designed to withstand horizontal loads. In seismic fortification zones, horizontal loads are mainly generated by horizontal seismic forces; therefore, shear walls are also known as wind-resistant walls, earthquake-resistant walls, or structural walls.

[0003] In existing prefabricated shear wall construction, multiple vertical steel bars are fixed on the ground, and then modular shear wall blocks are threaded through the steel bars. The steel bars are quite high, and when shear wall blocks are stacked through the steel bars, hoisting equipment is needed to lift the shear wall blocks, which makes the construction of shear wall blocks inconvenient. Summary of the Invention

[0004] To facilitate the construction of prefabricated shear walls, this application provides a prefabricated seismic-resistant shear wall.

[0005] This application provides a prefabricated seismic-resistant shear wall using the following technical solution:

[0006] A prefabricated seismic-resistant shear wall includes a base, wall modules, and connecting bars. The wall modules and connecting bars are arranged opposite each other. Multiple sets of wall modules are arranged along the length of the base. Each set of wall modules includes multiple wall modules arranged vertically. Adjacent wall modules are interconnected. The lower wall module in the vertical direction is connected to the base. The connecting bars are arranged opposite to the wall modules, and their axial direction is vertical. The connecting bars penetrate the wall modules. The wall modules have through holes for the connecting bars to pass through. The diameter of the through holes is larger than the cross-sectional diameter of the connecting bars. Adjacent connecting bars are connected by connecting components. The lower connecting bar in the vertical direction is also connected to the base by connecting components.

[0007] By adopting the above technical solution, the wall module is first connected to the base. Then, a connecting bar is passed through the wall module through the through hole and connected to the base. Then, the second wall module is connected to the wall module that has been connected to the base. Another connecting bar is connected to the first connecting bar, and so on. The wall modules and connecting bars are stacked in sequence according to the required building height. Then, concrete is poured into the through hole to complete the construction of the wall. Compared with passing the module through a whole steel bar, it is easier to construct the prefabricated shear wall.

[0008] Optionally, a positioning plate is connected to the side wall of the wall template facing the ground. Multiple positioning plates are provided along the length of the base. Mounting grooves are provided on the side wall of the wall template away from the ground and on the side wall of the base away from the ground. A gear is rotatably connected in the mounting groove. The axial direction of the gear is horizontal and perpendicular to the length of the base. The positioning plate near the gear has teeth on its side wall near the gear and meshes with the gear. An insert plate for locking the positioning plate in the mounting groove is slidably connected to the side wall of the mounting groove along the length of the base. The insert plate has teeth and meshes with the gear.

[0009] By adopting the above technical solution, the wall module moves toward the base or the wall module below it. The positioning plate with meshing teeth on the wall module meshes with the gears on the base and the gears on the wall module below it. The gears drive the insert plate to move, and the insert plate is inserted into the positioning plate, locking the positioning plate in the mounting groove, thereby realizing the connection between the wall module and the base and the wall module below it.

[0010] Optionally, the connecting assembly includes a connecting block, which is T-shaped. The vertical part of the connecting block is connected to the axial position of the end of the connecting rib near the ground. The horizontal part of the connecting block, away from its vertical part, does not exceed the side wall of the connecting rib. The end of the connecting rib away from the connecting block and the base are provided with a limiting groove and a recess. The recess is arranged radially along the connecting rib. The limiting groove is located at the bottom of the recess. The limiting groove is circular with the axis of the connecting rib as the center. The connecting block slides in conjunction with the limiting groove and the recess.

[0011] By adopting the above technical solution, with the connecting block facing the ground, the connecting rib passes through the wall module through the through hole. The connecting block is inserted into the groove on the base and the groove on the connecting rib located below. It is then inserted into the limiting groove. Then the connecting rib is rotated, and the horizontal part of the connecting block is located in the limiting groove, while the vertical part of the connecting block is located in the groove, so that the connecting rib is connected to the base.

[0012] Optionally, a clearance groove is provided on the side wall of the through hole.

[0013] By adopting the above technical solution, after the concrete is poured, it fills the clearance groove, thereby improving the stability of the connection between the concrete and the wall module.

[0014] Optionally, a positioning rod is slidably connected to the sidewall of the through hole along the radial direction of the through hole, and the positioning rod is used to limit the shaking of the connecting rib.

[0015] By adopting the above technical solution, the positioning rod is inserted into the connecting bar, which facilitates the positioning of the connecting bar, reduces the shaking of the connecting bar, and improves the stability between the concrete and the connecting bar after the concrete is poured.

[0016] Optionally, a connecting column is coaxially connected to the end of the connecting rib away from the connecting block. The cross-sectional diameter of the connecting column is larger than that of the connecting rib, and the diameter of the connecting column is smaller than that of the through hole. The groove and the limiting groove are provided at the end of the connecting column away from the connecting rib. A stop plate is slidably connected to the side wall of the through hole along the radial direction of the through hole. The stop plate abuts against the connecting column. A sliding hole for the stop plate to move is provided on the opposite side wall of the through hole near the ground. The length direction of the sliding hole is arranged along the radial direction of the through hole. A compression spring is connected to the bottom of the sliding hole. The end of the compression spring away from the sliding bottom is connected to the stop plate. The wall module is connected by a panel, which is slidably connected to the wall module along the radial direction of the through hole via a clearance groove. The positioning rod is disposed opposite to the panel and is located below the panel opposite to it. The side wall of the through hole is provided with a positioning groove for the positioning rod to slide. The wall module is provided with an installation cavity, which is connected to the clearance groove, the positioning groove, and the sliding hole. A connecting rod is hinged between the panel and the positioning rod opposite to it. The connecting rod is located in the installation cavity and is hinged to the wall template. A connecting plate is connected to the abutment plate, and the end of the panel away from the axis of the through hole is connected to the connecting plate.

[0017] By adopting the above technical solution, when the connecting rib is connected to the base, the connecting column pushes the abutment away from the center of the through hole. The abutment moves the insert away from the through hole through the connecting plate, so that the insert moves toward the side wall of the through hole into the clearance groove. The movement of the insert drives the connecting rod to rotate, and the connecting rod pushes the positioning rod toward the through hole, and the positioning rod is inserted into the slot.

[0018] Optionally, the side wall of the connecting column is provided with a slot for the positioning rod to be inserted. The bottom of the slot is provided with a spring groove. The bottom of the spring groove is connected to a stop block by a spring. The stop block slides radially along the through hole. When the spring is in its natural state, the end of the stop block away from the spring is located in the slot. The side wall of the connecting column is provided with a sliding cavity. The sliding cavity communicates with the spring groove and the slot. A locking rod is slidably connected to the connecting column along the connecting column axis. The locking rod is U-shaped and located in the sliding cavity. The opening of the locking rod faces the slot. One end of the locking rod is inserted into the slot and connected to the positioning rod. The other end is set as an inclined surface. The inclined surface on the locking rod faces away from the slot opening. The side wall of the stop block is provided with a push groove. The bottom of the push groove is inclined towards the slot. The end of the locking rod with the inclined surface slides in cooperation with the push groove.

[0019] By adopting the above technical solution, the positioning rod pushes the abutment into the spring groove, and under the action of the elastic element, the locking rod moves toward the slot. The locking rod is inserted into the positioning plate, thereby fixing the connecting column in the through hole.

[0020] Optionally, a guide groove is provided on a vertical surface of the wall module facing the length direction of the base, and a guide strip is connected to the side wall of the wall module away from the guide groove. The guide strip and the guide groove slide in a vertical direction.

[0021] By adopting the above technical solution, the cooperation between the guide strip and the guide groove provides guidance for the connection between adjacent wall modules in the horizontal direction.

[0022] Optionally, a connecting groove is provided on the side wall of the wall module through which the through hole is penetrated. The connecting groove communicates with the through hole and is provided along the length of the side wall. The connecting groove penetrates the side wall of the wall module facing the horizontally adjacent wall module.

[0023] By adopting the above technical solution, the connecting grooves between adjacent wall modules are opposite each other, and the connecting grooves between the wall module and the base are opposite each other to form a through groove. The through grooves between adjacent wall modules are connected in the horizontal direction. Concrete is poured into the through hole, and the concrete is filled in the through hole and the through groove, which makes it easy to connect adjacent wall modules together.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. First, connect the wall module to the base. Then, pass a connecting bar through the through hole through the wall module and connect it to the base. Then, connect the second wall module to the wall module that has already been connected to the base. Connect another connecting bar to the first connecting bar, and so on. Stack the wall modules and connecting bars according to the required height. Then, pour concrete into the through hole to complete the construction of the wall. Compared with passing the module through a whole steel bar, it is easier to construct the prefabricated shear wall.

[0026] 2. The wall module moves toward the base or the wall module below it. The positioning plate with teeth on the wall module meshes with the gears on the base and the wall module below it. The gears drive the insert plate to move. The insert plate is inserted into the positioning plate and locks the positioning plate in the mounting slot, thus realizing the connection between the wall module and the base and the wall module below it.

[0027] 3. With the connecting block facing the ground, insert the connecting rod through the through hole into the wall module, insert the connecting block into the groove on the base and the groove on the connecting rod located below, continue to insert into the limiting groove, and then rotate the connecting rod.

[0044] The implementation principle of the prefabricated seismic shear wall proposed in this application is as follows:

[0045] First, move a wall module 2 toward the base 1. The gear 9 on the base 1 engages with the positioning plate 7 on the wall module 2, which has teeth. The gear 9 drives the insert plate 10 to move, passing through the through-hole 11 near the gear 9 until the insert plate 10 is inserted into the through-hole 11 on the positioning plate 7 away from the gear 9, and the wall module 2 abuts against the base 1. Then, move the connecting block 13 toward the base 1, and insert the connecting rib 3 through the through-hole 4 into the wall module 2. The connecting block 13 is inserted into the groove 17 on the base 1 and then into the limiting groove 18. Then, rotate the connecting rib 3 so that the horizontal part of the connecting block 13 is in the limiting groove 18 and the vertical part of the connecting block 13 is in the groove 17, making... The connecting rib 3 is connected to the base 1. During the movement of the connecting rib 3, the connecting post 12 moves toward the base 1. When the connecting rib 3 is connected to the base 1, the connecting post 12 pushes the abutment plate 14 away from the center of the through hole 4. The abutment plate 14 drives the insert plate 15 away from the through hole 4 through the connecting plate 31, so that the insert plate 15 moves toward the side wall of the through hole 4 into the clearance groove 19. The movement of the insert plate 15 drives the connecting rod 29 to rotate. The connecting rod 29 pushes the positioning rod 16 toward the through hole 4. The positioning rod 16 is inserted into the slot 23. The positioning rod 16 pushes the abutment block 25 into the spring groove 24. Under the action of the elastic element, the locking rod 27 moves toward the slot 23. The locking rod 27 is inserted into the positioning plate 7, thereby fixing the connecting post 12 in the through hole 4.

[0046] After the wall module 2 near the base 1 is inserted into the base 1, the wall modules 2 are stacked on the installed wall modules 2 near the base 1. The gear 9 on the lower wall module 2 meshes with the positioning plate 7 with teeth on the upper wall module 2. The gear 9 drives the insert plate 10 to move. The insert plate 10 passes through the through hole 11 near the gear 9 until it is inserted into the through hole 11 on the positioning plate 7 away from the gear 9. Adjacent wall modules 2 abut and connect together. Then, with the connecting block 13 facing the base 1, the connecting rib 3 passes through the through hole 4 through the wall module 2. The connecting block 13 is inserted into the groove 17 on the lower connecting post 12 and then into the limiting groove 18. Then, the connecting rib 3 is rotated. The horizontal part of the connecting block 13 is in the limiting groove 18, and the vertical part of the connecting block 13 is in the groove 17, so that adjacent connecting blocks 13 abut and connect together. The reinforcing bars 3 are connected together. During the connection process of adjacent reinforcing bars 3, the connecting column 12 moves toward the wall module 2 located below. After the adjacent reinforcing bars 3 are connected together, the connecting column 12 pushes the abutment plate 14 on its corresponding wall module 2 away from the center of the through hole 4, so that the insert plate 15 moves toward the side wall of the through hole 4 into the clearance groove 19. The positioning rod 16 is inserted into the slot 23. The positioning rod 16 pushes the abutment block 25 into the spring groove 24. The locking rod 27 is inserted into the positioning plate 7, thereby fixing the connecting column 12 in the through hole 4. The wall modules 2 are stacked and installed in this way. The stacked wall through holes 4 are opposite each other, the connecting grooves 6 between adjacent wall modules 2 are opposite each other, and the connecting grooves 6 between the wall module 2 and the base 1 are opposite each other to form a through groove. Concrete is poured into the through hole 4. The concrete fills the through hole 4 and the through groove. After the concrete dries, the construction of the prefabricated shear wall is completed.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
