Reinforcing structure between longitudinal and transverse walls of cold-formed thin-walled section steel house

Abstract

The invention discloses a reinforcing structure between longitudinal and transverse walls of a cold-formed thin-walled section steel house. The reinforcing structure comprises beams and wall frame columns, wherein the beams and the wall frame columns are mutually matched. The wall frame columns comprise lower-layer columns and upper-layer columns; the beams comprise floor beams (23), lower-layer house U-shaped beams (7) and upper-layer house U-shaped beams (8); the tops of the lower-layer columns are inlaid in openings of the U-shaped steel top beams (7) and fixed; the bottoms of the upper-layer columns are inlaid in openings of the U-shaped steel bottom beams (8) and fixed; the lower-layer columns and the upper-layer columns are connected through connecting pieces (12); anti-pulling pieces (17) are connected between the lower-layer columns and the U-shaped steel top beams (7), and anti-pulling pieces (17) are connected between the upper-layer columns and the U-shaped steel bottom beams (8); and H-shaped reinforcing components (6) between steel layers are connected between the U-shaped steel top beams (7) and the U-shaped steel bottom beams (8). The reinforcing structure is characterized in that oblique supporting pieces are connected between parts of the upper-layer columns and the U-shaped steel bottom beams (8) and / or oblique supporting pieces are connected between parts ofthe lower-layer columns and the U-shaped steel top beams (7).

Description

technical field [0001] The invention relates to an assembled cold-formed thin-walled steel building vertical and horizontal wall strengthening structure system, which is especially suitable for installation in low-rise and multi-layered assembled cold-formed thin-walled steel structure buildings, and belongs to the technical field of construction engineering. Background technique [0002] The load-bearing composite wall of cold-formed thin-walled steel houses is usually composed of cold-formed thin-walled steel wall frame columns, inner filling insulation cotton and outer covering gypsum board, etc., which is easy to realize resource recycling; wall panels have good thermal insulation performance , reduce energy consumption during use, and meet the national green environmental protection requirements; main components such as wall frame columns, floor beams, and wall panels are processed in the factory and then shipped to the site for assembly. The parts are light in weight, ...

Problems solved by technology

[0004] Chinese patent application No. 201611100380.1 discloses a cold-formed thin-walled steel beam-column structure system for multi-storey houses, including beams and wall frame columns that cooperate with each other. In this patent technology, H-shaped steel laminated welded composite reinforcement components and angle steel work together , can effectively improve the torsion resistance of the inner wall, but when the reinforcing component is applied to the wall, it can only improve the resistance of the wall at the connection between the floors

However, the low-cycle reciprocating loading test of the composite wall-composite floor slab connection shows that when the connection is loaded to the limit state of the bearing capacity, the self-tapping screws in the area between the wall and the floor slab will fail due to the reciprocating load, which will also cause edge failure. The failure of the wall panels at the top and corners will cause the failure of the connection between the wall and the floor, and induce the continuous collapse of the structure
