Description

Technical Field

[0001] This invention relates to the field of steel structure buildings, specifically to a device and construction method for adjusting the deformation of shear-resistant steel plate walls during installation. Background Technology

[0002] Shear-resistant steel plate walls, designed into the structure of super high-rise buildings, play a crucial role in the safety of these buildings as the primary lateral force resisting structure. However, large-area shear-resistant steel plate walls are often prone to torsion and deformation due to insufficient stiffness, which can prevent them from being properly positioned and connected to the steel frame columns, thus affecting the installation quality.

[0003] The existing method is to use flame straightening to straighten the torsional deformation of the shear-resistant steel plate wall. This method has poor control over the torsional deformation of the shear-resistant steel plate wall, low construction efficiency, and high implementation cost.

[0004] A search using the keyword "steel plate wall deformation" revealed three prior art documents: ① an adjustable steel plate wall deformation correction device (publication number CN210907471U); ② an anti-deformation device for steel plate walls (publication number CN213653894U); and ③ a mechanical device for preventing welding deformation of steel plate walls (publication number CN217045185U). All three documents relate to adjusting and controlling the deformation of steel plate walls. Specifically, ① uses external pressure to adjust local convex deformation of the steel plate wall; ② uses a jacking plate to support the side of the steel plate wall, thereby preventing deformation during welding; and ③ provides a working platform to constrain welding deformation of the steel plate wall. Summary of the Invention

[0005] The present invention aims to overcome the defects of the prior art and provide a device and construction method for adjusting the deformation of shear-resistant steel plate walls during installation, thereby solving the problem that the deformation of the shear-resistant steel plate walls prevents them from being properly positioned and connected to the steel column.

[0006] To solve the above-mentioned technical problems, the present invention is implemented as follows:

[0007] A device for adjusting the deformation of a shear-resistant steel plate wall during installation includes a shear-resistant steel plate wall, characterized in that: tensioning devices are provided at least around the shear-resistant steel plate wall, and a balancing hanger is provided in the middle of the shear-resistant steel plate wall; when the shear-resistant steel plate wall is suspended in the air, the deformation of the shear-resistant steel plate wall is adjusted by tightening the chain hoist to drive the tensioning devices.

[0011] The device for adjusting the deformation of the shear-resistant steel plate wall during installation is characterized in that it further includes a hook and a hoisting wire rope. The top of the shear-resistant steel plate wall is provided with a lifting lug. One end of the hoisting wire rope is connected to the lifting lug, and the other end is connected to the hook.

[0012] The device for adjusting the deformation of the shear-resistant steel plate wall during installation is characterized in that: the shear-resistant steel plate wall is provided with balance bracket bolt holes and adjustment bracket bolt holes, the balance bracket is installed on the balance bracket bolt holes and fixed by high-strength bolts, and the adjustment bracket is installed on the adjustment bracket bolt holes and fixed by high-strength bolts.

[0013] The construction method of the device for adjusting the deformation of the shear-resistant steel plate wall during the installation process is characterized by: firstly, using drilling tools to drill holes for the balance hanger bolt holes and the adjustment hanger bolt holes on the tortuous and deformed shear-resistant steel plate wall;

[0014] Secondly, the hooks lift the shear-resistant steel plate wall into the air, and a balance hanger is installed on each side of the position of the balance hanger bolt hole and fixed with high-strength bolts; an adjustment hanger is installed on each side of the position of the adjustment hanger bolt hole and fixed with high-strength bolts.

[0015] Next, install the retaining ring, chain hoist, and adjusting wire rope between the balance bracket and the adjusting bracket;

The retaining ring 5, chain hoist 6, adjusting wire rope 7, and retaining ring 5 are sequentially connected between the balancing hanger and the adjusting hanger. After tightening the chain hoist, the adjusting wire rope pulls a tensioning device to adjust the deformation of the twisted shear-resistant steel plate wall 1. The shear-resistant steel plate wall has bolt holes 1.2 for the balancing hanger and bolt holes 1.3 for the adjusting hanger. The balancing hanger is installed in the bolt holes of the balancing hanger and fixed with high-strength bolts 4. The adjusting hanger is installed in the bolt holes of the adjusting hanger and fixed with high-strength bolts 4.

[0037] Adjustable bracket 3 includes an adjusting bracket ear plate 3.1, an adjusting bracket base plate 3.2, an adjusting bracket retaining ring hole 3.1a, and an adjusting bracket bolt hole 3.2a; the adjusting bracket ear plate has an adjusting bracket retaining ring hole for connecting the retaining ring; the adjusting bracket ear plate is welded to the adjusting bracket base plate, and the adjusting bracket base plate has an adjusting bracket bolt hole;

[0038] The balance hanger 2 includes a round tube 2.1, a round tube stiffening plate 2.2, a balance hanger top plate 2.3, a balance hanger bottom plate 2.4, a balance hanger retaining ring hole 2.3a, and a balance hanger bolt hole 2.4a. The balance hanger top plate and the balance hanger bottom plate have openings in the middle, and they are connected by a round tube. Round tube stiffening plates are provided around the edges. The balance hanger top plate has a balance hanger retaining ring hole, and the balance hanger bottom plate has a balance hanger bolt hole.

[0039] The top of the shear-resistant steel plate wall 1 is equipped with a lifting lug 1.1. One end of the lifting wire rope 10 is connected to the lifting lug, and the other end is connected to the lifting hook 9.

[0040] The construction method for adjusting the deformation of the shear-resistant steel plate wall during installation is as follows: First, using a drilling tool, drill holes 1.2 for the balance hanger bolts and 1.3 for the adjusting hanger bolts on the tortuous and deformed shear-resistant steel plate wall 1. Several studs 1.4 are provided on the shear-resistant steel plate wall.

[0041] Secondly, the hook 9 lifts the shear-resistant steel plate wall 1 into the air, and installs a balance hanger 2 on both sides of the position of the balance hanger bolt hole 1.2 and fixes it with high-strength bolts 4; install an adjustment hanger 3 on both sides of the position of the adjustment hanger bolt hole 1.3 and fix it with high-strength bolts 4.

[0042] Next, install the retaining ring 5, chain hoist 6, and adjusting wire rope 7 between the balance hanger 2 and the adjusting hanger 3;

[0043] Then, tighten the chain hoist 6 and pull the adjusting bracket 3 to adjust the deformation of the twisted shear-resistant steel plate wall 1 until the external dimensions of the shear-resistant steel plate wall 1 meet the design requirements.

[0044] Finally, the shear-resistant steel plate wall 1 is hoisted between the steel columns 8 to complete the installation of the shear-resistant steel plate wall 1. After the shear-resistant steel plate wall 1 is welded to the steel columns 8, all the balance hangers 2, adjustment hangers 3, high-strength bolts 4, clasps 5, chain hoists 6 and adjustment wire ropes 7 are removed.

[0045] This application addresses the issue of large-area shear-resistant steel plate walls in ultra-high-rise buildings being prone to torsion and deformation due to insufficient rigidity. It addresses this by drilling holes in the shear-resistant steel plate walls and installing hangers, clasps, adjusting wire ropes, and chain hoists while the shear-resistant steel plate walls are suspended in the air. Tightening the chain hoists drives the hangers to adjust the deformation of the shear-resistant steel plate walls, ensuring that the external dimensions of the shear-resistant steel plate walls meet design requirements and that the edges can be quickly positioned during installation.
