Description

Steel beam web rectangular orifice reinforcing member in steel structure building Technical Field The utility model belongs to the technical field of steel structure buildings, and particularly relates to a steel beam web rectangular orifice reinforcing member in a steel structure building. Background In steel construction building, offer the rectangular drill way on girder steel web, can make pipeline or cable pass through the girder steel smoothly, avoid carrying on extensive change to the steel structure spare, also can guarantee the effective utilization of building space simultaneously, make building layout more reasonable. However, the effective cross-section area of the web plate can be weakened by forming rectangular holes in the web plate of the steel beam, the shearing resistance and bending resistance of the web plate are reduced, and meanwhile, stress concentration phenomenon can be generated at the edge of the hole opening, so that local deformation and even cracking are easily caused, the overall performance and safety of the steel beam are affected. Disclosure of utility model The utility model aims to provide a steel beam web rectangular hole opening reinforcing member in a steel structure building, which has the advantages that a steel beam can bear larger load, the steel beam is cooperatively connected with an original web through a structure of a reinforcing plate and a stiffening plate, bending moment and shearing force are jointly born, reinforcing nodes are reinforced, the potential structural safety hazard caused by holes can be reduced, the structural failure risk is reduced, and the overall safety of an engineering structure is ensured, so that the problems of the background technology are solved. The technical scheme includes that the steel beam web rectangular hole reinforcing member comprises main steel, transverse connection steel is fixedly connected to the right side of the main steel, stiffening rib plates are installed on the front side of the transverse connection steel web, a plurality of reinforcing plates are fixedly connected to the top and the bottom of each stiffening rib plate, L-shaped plates are fixedly connected to the upper side, the lower side and the left side of each stiffening rib plate through bolts, the surfaces of the L-shaped plates are fixedly connected with the transverse connection steel through bolts, supporting plates are fixedly connected to the left side and the right side of each stiffening rib plate through bolts, two opposite diagonal bracing plates are fixedly connected to the opposite sides of the top reinforcing plates, a lower bottom plate is fixedly connected to the top of the transverse connection steel, the lower bottom plate is located between the two reinforcing plates on the left side of the bottom, and inclined plates are fixedly connected to the top of the lower bottom plate.
