Problems solved by technology

When making steel load-bearing plates, the steel frame or steel beams are fixed in the middle of two steel plates to form a composite steel load-bearing plate. Using solid plate steel as the steel frame or steel beams will greatly increase the overall weight of the steel load-bearing plate
In addition, with the increase in the strength requirements of steel materials in practical applications, the strength of the above-mentioned angle steel, square steel or I-beam can no longer meet the requirements for high strength; under a larger load-bearing capacity, the strength of the above steel materials is low , prone to deflection deformation

Abstract

The invention discloses a light steel beam and a structural steel frame thereof. The structural steel frame comprises a frame body and two shearing force bodies, wherein the frame body is provided with a bearing base body and a connecting base body perpendicular to the bearing base body, the two shearing force bodies are fixedly connected to the two side faces of the connecting base body respectively, the bearing base body, the connecting base body and the shear force bodies all extend in the length direction of the light steel beam, each shear force body is provided with multiple shear force base bodies connected in sequence with certain angles formed between the shear force base bodies, and the shear force base bodies at corresponding positions of the two shear force bodies are arranged in a crossing mode. In this way, the overall weight of the structural steel frame is effectively reduced, structural strength is improved greatly, and the development requirements for light weight and high strength of the steel beam are fully met.

Description

technical field [0001] The invention relates to the technical field of building steel, in particular to a light steel beam and its structural steel skeleton. Background technique [0002] Steel skeleton or steel beams are mainly used to make steel load-bearing slabs, working platform beams, floor beams in multi-storey buildings, roof purlins, etc. It has the function of support and load-bearing, and requires strong compressive and tensile strength; at present, steel skeletons or steel beams are generally made of solid plate steel, and their own weight is large. [0003] In the prior art, angle steels, square steels or I-beams are usually used as steel skeletons or steel beams. In practical application, this type of steel is a solid steel, and its own weight is relatively large, that is to say, it consumes more steel, so the cost is relatively high. When making the steel load-bearing plate, the steel frame or steel beam is fixed in the middle of two steel plates to form a c...
