Anti-shear reinforcing structure of steel beam
The invention provides an anti-shear reinforcing structure of a steel beam. The anti-shear reinforcing structure comprises anti-bending steel plate walls as well as steel beams at the upper and lower ends of the anti-bending steel plate walls, wherein the steel beams are H-shaped beams or I-shaped beams, equivalent eccentric crossed supports are crossed with the steel beams to form vertical resultant force application points, each steel beam comprises an anti-shear reinforcing section and a non-anti-shear reinforcing section, the height of the each steel beam is hb, the anti-shear reinforcing section comprises an area between the vertical resultant force application points corresponding to two adjacent anti-bending steel plate walls, and an area formed by outward extending of the vertical resultant force application points by 1/2 hb, two sides of webs of the anti-shear reinforcing sections are provided with corrugated steel plates, each corrugated steel plate comprises a first horizontal section, a second horizontal section and an oblique section, at the vertical resultant force application points, the first horizontal sections are tightly welded to the webs of the steel beams, and the oblique sections are welded to two flanges of the anti-shear reinforcing sections. According to the invention, the anti-shear bearing force of the steel beams is improved, the webs do not need to be heightened, so that the functions of a building are not influenced, and moreover, the difficulties in purchasing and welding due to adoption of a thick board or a height-variable beam as the steel beam are avoided.
