Description

Technical Field

[0001] The utility model relates to the technical field of shear walls, in particular to a horizontal seam connection node of a double steel plate shear wall. Background Art

[0002] The main forms of existing double steel plate shear walls are: bolted double steel plate shear wall, T-shaped stiffening rib double steel plate shear wall, plate-connected double steel plate shear wall, tension bolt double steel plate shear wall and mixed connection double steel plate shear wall.

[0003] The common feature of the above five types of steel plate shear walls is that they are steel plates on both sides and filled with concrete. When the vertical joints are connected, the horizontal joints are welded on site. The horizontal welds are difficult to weld on site and due to gravity, the molten metal flows downward during welding, resulting in the weld being thin at the top and thick at the bottom. The thickness of the thin part is less than the thickness of the steel plate. This practice weakens the shear resistance of the shear wall steel plate at the weld to a certain extent. At the same time, it is not conducive to the connection with other structures such as floor slabs and beams. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the utility model is that the molten metal flows downward during welding, resulting in the weld being thin at the upper part and thick at the lower part, so that the shear resistance of the shear wall steel plate is weakened to a certain extent at the weld position, which is not conducive to the connection with other structures such as floor slabs and beams.

[0008] As an improvement, the T-shaped connecting steel member includes a vertical plate and a horizontal plate. The horizontal plate is installed in the middle of one side wall of the vertical plate. The horizontal plate passes through the upper stress-bearing steel plate and the lower stress-bearing steel plate and is welded.

[0009] As an improvement, multiple groups of plug blocks are installed on the side where the vertical plate is connected to the horizontal plate, and the multiple groups of plug blocks are arranged on the upper and lower sides of the horizontal plate. The lower part of the upper stress-bearing steel plate and the upper part of the lower stress-bearing steel plate are respectively provided with sockets for inserting the plug blocks.

[0010] As an improvement, a sealing gasket is installed on one side wall of the vertical plate mounting plug block.

[0011] As an improvement, a plurality of guide holes are provided on the transverse plate.

[0012] As an improvement, the wall connector includes two sets of U-shaped mounting frames, which are installed at relative positions of two sets of load-bearing steel plates on the same side. A threaded rod is installed through the middle of the U-shaped mounting frame, and a nut is installed on the outer side of the end of the threaded rod.
