Description

Technical Field

[0001] This invention relates to the field of building technology, and more specifically, to a lattice-type steel-concrete shear wall and its construction method. Background Technology

[0002] Shear walls, as structural members that simultaneously bear vertical and horizontal loads, are widely used in building structural systems. Traditional reinforced concrete shear wall construction requires a large amount of manpower on site, involving first binding the reinforcing cage, then erecting the formwork, pouring concrete, and finally removing the formwork. This not only results in slow construction speed and long cycle, but also causes problems such as wastewater discharge and dust pollution during formwork removal. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a lattice-type steel-concrete shear wall and a construction method thereof to solve the above problems.

[0004] The present invention adopts the following solution:

[0005] This application provides a lattice-type steel-concrete shear wall, including four longitudinal angle steels, multiple longitudinal steel sections, gusset plates, profiled steel sheets, and transverse angle steels;

[0006] The longitudinal angle steel and the longitudinal profile steel form a wall structure, with the angle steel located at the four corners of the wall structure. The longitudinal profile steel is symmetrically spaced along the length of the wall structure. The connecting plates are spaced along the height direction and connected to two symmetrical longitudinal profile steels. The transverse angle steel is spaced along the height direction and connected to the outer perimeter of the wall structure. The transverse angle steel is provided with a snap-fit ​​groove. The profiled steel sheet is snapped into the snap-fit ​​groove through a snap-fit ​​part and is placed around the outer perimeter of the wall structure. The profiled steel sheet is filled with concrete.

[0007] Furthermore, the longitudinal steel section is a T-shaped steel section; the connecting plate is connected to the web of two symmetrical T-shaped steel sections.

[0008] Furthermore, the connecting plate is connected to the longitudinal steel section, and the transverse angle steel is connected to the longitudinal angle steel and the longitudinal steel section by welding.

[0009] Furthermore, the transverse angle steel includes two first transverse angle steels in the width direction of the wall structure and a second transverse angle steel in the length direction.

[0010] Furthermore, the profiled steel sheet includes two first profiled steel sheets for the width direction of the wall structure and a second profiled steel sheet for the length direction.

[0011] Furthermore, the second profiled steel sheet has continuous locking edges on both sides.

[0012] Furthermore, the profiled steel sheet is provided with a continuous snap-fit ​​portion along the height direction, which can pass through the snap-fit ​​groove from top to bottom or from bottom to top to form a snap-fit.

[0013] The present invention also provides a construction method for the aforementioned lattice-type steel-concrete shear wall, comprising the following steps:

[0014] S1: Weld longitudinal angle steel and longitudinal profile steel to form a wall structure;

[0015] The longitudinal angle steel and longitudinal section steel are placed according to the wall structure, with the angle steel set at the four corners of the wall structure; the longitudinal section steel is symmetrically spaced along the length of the wall structure; and then the gusset plates are welded at intervals along the height direction to the two symmetrical longitudinal section steels.

[0016] S2: The transverse angle steel is spaced along the height direction on the outer periphery of the wall structure and welded to the longitudinal angle steel and longitudinal steel section;

[0017] S3: Hoist the profiled steel sheet from top to bottom or bottom to top and clamp it onto the horizontal angle steel;

[0018] S4: Pour concrete inside the profiled steel sheet.

[0019] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0020] 1. Using common structural steel, angle steel and profiled steel sheets as materials, the design and construction are simple and efficient. It can realize industrialized production according to customized specifications and modules, standardized and modular use, and can reduce the cost currently used in super high-rise buildings.

[0021] 2. While serving as formwork, profiled steel sheets can also be used as wall materials, eliminating the need for formwork removal. At the same time, they can form a solid whole with the profiled steel to work together and improve the load-bearing performance of the shear wall. Attached Figure Description

[0029] Example

[0030] Combination Figures 1 to 4 As shown, this embodiment provides a lattice-type steel-concrete shear wall, including four longitudinal angle steels 4, multiple longitudinal steel sections, connecting plates 3, profiled steel sheets, and transverse angle steels;

[0031] The longitudinal angle steel 4 and the longitudinal profile steel form a wall structure, with the angle steel located at the four corners of the wall structure. The longitudinal profile steel is symmetrically spaced along the length of the wall structure. The connecting plates 3 are spaced along the height direction and connected to two symmetrical longitudinal profile steels. The transverse angle steel is spaced along the height direction and connected to the outer perimeter of the wall structure. The transverse angle steel is provided with a snap-fit ​​groove 9. The profiled steel sheet is snapped into the snap-fit ​​groove 9 through the snap-fit ​​part 8 and surrounds the outer perimeter of the wall structure. The profiled steel sheet is filled with concrete 11.

[0032] Using common structural steel, angle steel, and profiled steel sheets as materials, the design and construction are simple and efficient. It allows for industrialized production according to customized specifications and modules, standardized and modular use, and can reduce costs currently incurred in super high-rise buildings. Profiled steel sheets can serve as both formwork and wall material, eliminating the need for formwork removal. They also form a strong, integrated structure with the structural steel, improving the load-bearing capacity of the shear wall.

[0033] Specifically, such as Figure 1 As shown, the longitudinal steel section is a T-shaped steel 2, with its central web facing inward; the connecting plate 3 is welded to the webs of two symmetrically positioned T-shaped steels 2. The transverse angle steel includes two first transverse angle steels 6 for the width direction of the wall structure, and a second transverse angle steel 5 for the length direction. The longitudinal plate of the transverse angle steel is welded to the flange plates of the longitudinal angle steel 4 and the T-shaped steel 2; the transverse plate of the transverse angle steel is provided with the snap-fit ​​groove 9. Figure 2 As shown, the profiled steel sheet includes two first profiled steel sheets 1 for the width direction of the wall structure and a second profiled steel sheet 7 for the length direction. The profiled steel sheet has a continuous snap-fit ​​portion 8 along its height direction, which can pass through the snap-fit ​​groove 9 from top to bottom or bottom to top to form a snap-fit. The second profiled steel sheet 7 also has continuous engaging edges 10 on both sides to cover the first profiled steel sheet 1 on the inside, preventing concrete 11 from flowing out of the gaps at the joints of the profiled steel sheets during pouring. The above method uses profiled steel, angle steel, and profiled steel sheets as materials to form the wall structure through welding. Compared to the binding of reinforcing cages, the construction speed is faster and the cycle is shorter. Furthermore, the profiled steel sheet is convenient and quick to install as a pouring formwork, and can be directly used as wall material, eliminating the need for formwork removal and thus avoiding problems such as wastewater discharge and dust pollution caused by formwork removal.

[0034] The following details the construction steps for this lattice-type steel-concrete shear wall:

[0035] S1: Weld longitudinal angle steel and longitudinal profile steel to form a wall structure;

[0036] The longitudinal angle steel and longitudinal section steel are placed according to the wall structure, with the angle steel set at the four corners of the wall structure; the longitudinal section steel is symmetrically spaced along the length of the wall structure; and then the gusset plates are welded at intervals along the height direction to the two symmetrical longitudinal section steels.

[0037] S2: The transverse angle steels are spaced apart along the height direction on the outer periphery of the wall structure and welded to the longitudinal angle steels and longitudinal steel sections;

[0038] S3: Hoist the profiled steel sheet from top to bottom or bottom to top and clamp it onto the horizontal angle steel;

[0039] S4: Pour concrete inside the profiled steel sheet.
