Corrugated web H-shaped steel beam

Abstract

The invention discloses a corrugated web H-shaped steel beam, and belongs to the technical field of building construction tools. The corrugated web H-shaped steel beam comprises an upper wing plate, alower wing plate, a corrugated web, vertical grooves, an upper positioning hole, a lower positioning hole and mounting holes, wherein the upper wing plate and the lower wing plate are fixedly connected to the upper and lower ends of the corrugated web respectively, and the vertical grooves are distributed in two side surfaces of the corrugated web at equal intervals. According to the corrugated web H-shaped steel beam, the staggered vertical grooves are formed in both sides of the corrugated web, so that the friction strength of the side surfaces of the corrugated web can be increased in thecondition that the support strength of the corrugated web is not influenced, and when the steel beam and concrete are poured, the connection firmness is increased; a lifting lug is arranged and has splitting and combining functions, so that the disassembly time of the lifting lug is saved, and the lifting lug can be repeatedly used; and a positioning block and a connecting base are arranged, so that the steel beam and other main beams can be conveniently and rapidly positioned and connected, and the installation efficiency of the steel beam is greatly improved.

Description

technical field [0001] The invention relates to the technical field of building construction tools, and more specifically relates to a corrugated web H-shaped steel girder. Background technique [0002] The corrugated steel web steel girder is generally composed of steel top plate, steel bottom plate and corrugated steel web. Force, the overall structure formed in this way bears the load together. [0003] At present, in order to ensure the support strength of the corrugated web H-shaped steel beam, most of the corrugated webs do not have rough hook grooves to increase the contact area with the concrete, thereby reducing the connection between the steel beam and the concrete. Firmness, and most of the lifting lugs set on the existing steel beams are fixed to the surface of the steel beams by welding. When disassembling, it takes more time to cut, and it may make the lifting lugs unable to be reused. When steel girders are installed with other main girders, they are mostly ...

Problems solved by technology

[0003] At present, in order to ensure the support strength of the corrugated web H-shaped steel girder, most of the corrugated webs do not have rough hook grooves to increase the contact area with the concrete, thereby reducing the connection between the steel girder and the concrete. Firmness, and most of the lifting lugs set on the existing steel beams are fixed to the surface of the steel beams by welding. When disassembling, it takes more time to cut, and it may make the lifting lugs unable to be reused. When steel girders are installed with other main girders, most of them are welded, which not only makes the construction inconvenient, but also affects the mechanical properties of the steel girder joints to a certain extent.
