Description

Technical Field

[0001] This utility model relates to the field of steel plate connection technology for steel plate shear walls, and specifically to an installation and positioning device for steel plate shear walls. Background Technology

[0002] In modern building structures, steel plate shear walls are widely used due to their excellent lateral force resistance performance. However, a series of technical problems are often encountered in the welding process of steel plate shear walls.

[0003] In the current construction process, dents and deformations often occur when welding steel plates together. This not only affects the flatness of the shear wall's appearance but also severely weakens its structural strength and stability. This deformation problem usually stems from localized high temperatures during the welding process, leading to uneven thermal expansion and contraction of the material, which generates internal stress and causes the steel plate to dent. Once dents appear, they will directly affect the construction progress, as well as the load-bearing capacity and seismic performance of the shear wall, while also increasing construction costs and workload. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a steel plate shear wall installation and positioning device.

[0005] This utility model is achieved through the following technical solution:

[0006] A steel plate shear wall installation and positioning device includes adjacent steel plate bodies with a bevel for welding between them. Dovetail grooves are evenly distributed on both sides of the steel plate bodies. Positioning components to prevent deformation during welding are slidably connected in the corresponding dovetail grooves. The positioning components include a bracket, with sliders that match the dovetail grooves connected and fixed on the vertical rods on both sides of the bracket. A lead screw is threadedly slidably connected in the middle of the bracket. One end of the lead screw extends inward to the bracket and is movably connected to a positioning plate at its end. The other end of the lead screw extends outward to the bracket and is connected and fixed to a handwheel at its end.

[0007] Alternatively, the bracket may have a threaded hole in the middle that matches the lead screw.

[0008] Alternatively, two limiting optical axes are fixedly connected to the inner side of the bracket, and the corresponding limiting optical axes are slidably connected to the positioning plate.

[0009] Alternatively, reinforcing ribs may be provided on the inner side of the corners on both the upper and lower sides of the bracket.

[0010] Alternatively, a locking nut can be provided on the threaded sliding connection of the lead screw.

[0011] Alternatively, the positioning plate has a cavity in the middle, and a T-shaped block is rotatably connected inside the cavity. The T-shaped block is integrated with the lead screw.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: By adding positioning components, this utility model fundamentally solves a series of problems caused by the occurrence of depressions during welding between steel plates, greatly ensuring the flatness of the shear wall appearance, improving its structural strength and stability, while speeding up work efficiency, reducing construction costs, and alleviating labor intensity.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0017] like Figure 1 , 2 As shown, a steel plate shear wall installation and positioning device includes adjacent steel plate bodies 1, with a bevel 2 for welding between the adjacent steel plate bodies 1. Dovetail grooves 3 are evenly distributed on both sides of the steel plate bodies 1. Positioning components to prevent deformation during welding are slidably connected in the dovetail grooves 3. The positioning components include a bracket 4. Sliding blocks 5 that match the dovetail grooves 3 are connected and fixed on the vertical rods on both sides of the bracket 4. A screw 6 is threadedly slidably connected in the middle of the bracket 4. One end of the screw 6 extends inward to the bracket 4 and is movably connected to a positioning plate 7 at its end. The other end of the screw 6 extends outward to the bracket 4 and is connected and fixed to a handwheel 8 at its end.

[0018] like Figure 2 As shown, the bracket 4 has a threaded hole 9 in the middle that matches the lead screw 6.

[0019] like Figure 1 , 2 As shown, two limiting optical axes 10 are fixedly connected to the inner side of the bracket 4, and the corresponding limiting optical axes 10 are slidably connected to the positioning plate 7.

[0020] like Figure 1 As shown, reinforcing ribs 11 are provided on the inner side of the corners on both the upper and lower sides of the support 4 to prevent deformation of the support 4 during construction.

[0021] like Figure 1 , 2As shown, a locking nut 12 is threadedly slidably connected to the lead screw 6 to prevent the lead screw 6 from rotating on its own.

[0022] like Figure 2 As shown, a cavity 13 is provided in the middle of the positioning plate 7, and a T-shaped block 14 is rotatably connected inside the cavity 13. The T-shaped block 14 is integrally set with the lead screw 6.

[0023] The implementation principle of the steel plate shear wall installation and positioning device in this application embodiment is as follows:

[0024] When welding the bevel 2 of adjacent steel plate bodies 1, first insert the bracket 4 with the slider 5 into the corresponding dovetail groove 3. After insertion, turn the handwheel 8. When turning the handwheel 8, the lead screw 6 will rotate synchronously. When the lead screw 6 rotates, it will move forward. When the lead screw 6 moves forward, it will push the positioning plate 7 to move forward synchronously. When the positioning plate 7 moves forward, the positioning plate 7 will fit tightly with the steel plate body 1. After it fits tightly, turn the locking nut 12 to make the inner side of the side of the steel plate body 1 fit tightly and tighten the locking nut 12 to prevent the rotation of the lead screw 6 from causing a gap between the positioning plate 7 and the steel plate body 1. At the same time, the positioning plates 7 on both sides of the steel plate body 1 complete the positioning work of the adjacent steel plate body 1, so as to weld the bevel 2 and better prevent the adjacent steel plate body 1 from deforming during welding.

[0025] After welding is completed, first loosen the locking nut 12, then turn the handwheel 8 in the opposite direction to drive the lead screw 6 to rotate. As the lead screw 6 rotates, it will move the positioning plate 7 away from the steel plate body 1. After it is away from the steel plate body 1, push the bracket 4 to take it out of the dovetail groove 3 and install it on another adjacent steel plate body 1. Continue welding, and at the same time weld the bevel 2 covered by the positioning plate 7. The area of ​​the bevel 2 covered by the positioning plate 7 is small and will not cause deformation of the adjacent steel plate body 1 during welding.
