Description

Technical Field

[0001] This utility model relates to the field of general building construction technology, specifically to a support device for replacing and reinforcing concrete shear walls. Background Technology

[0002] During concrete construction and long-term use, insufficient strength of the concrete structure may occur, especially in load-bearing components such as shear walls, which can affect the structural safety of the building. Concrete replacement reinforcement is a method that strengthens the structure by replacing the problematic concrete with new concrete.

[0003] When reinforcing shear walls using the concrete replacement method, it is necessary to first remove the original concrete in areas with insufficient strength, and the removal area is usually slightly larger. Since the shear wall itself is a load-bearing component, the superstructure loses support after part of the concrete is removed. Therefore, the superstructure needs to be supported during shear wall replacement reinforcement. Patent document CN220815056U, entitled "A Support Device for Concrete Replacement Reinforcement," discloses a support device. However, the drawback is that existing technologies typically involve the complete removal of the concrete structure to be replaced, and existing building floor slabs are usually not used as load-bearing structures, making support relatively difficult. Utility Model Content

[0004] To address the above shortcomings, the purpose of this utility model is to provide a support device that facilitates local concrete replacement and reinforcement of shear walls.

[0005] Therefore, this utility model provides a support device for replacing and reinforcing concrete shear walls. The shear wall includes a region to be reinforced. An upper load-bearing component and a lower load-bearing component are respectively installed on the upper and lower sides of the region to be reinforced. The region to be reinforced includes several repair areas in the horizontal direction. The upper load-bearing component and the lower load-bearing component are connected by load-bearing support rods, which are installed on both sides of the current repair area.

[0006] Furthermore, the upper and lower load-bearing components include an L-shaped load-bearing plate with several fixing holes for fixing in conjunction with the reinforcing bars embedded in the shear wall.

[0007] Furthermore, a square steel pipe is welded and fixed to one side of the load-bearing plate, the square steel pipe being perpendicular to the length direction of the load-bearing plate, and a round pipe is welded and fixed to the square steel pipe, the round pipe being set in the same direction as the load-bearing plate.

[0008] Furthermore, the load-bearing support rod is provided with connectors at both ends, and each connector is provided with a U-shaped groove corresponding to the number of round tubes. The U-shaped grooves cooperate with the round tubes so that the connectors are supported below the round tubes.

[0009] Further, the load-bearing support rod can be moved laterally, so that the load-bearing support rod is erected in the corresponding area as needed.

[0010] Further, the load-bearing support rod can be moved laterally, so that the load-bearing support rod is erected in the corresponding area as needed.
