Problems solved by technology

However, in this splicing method, the shear force is transmitted to the web through bolts, and the web is a flat steel plate, so the number of bolts required and the amount of steel used for the web are large, and the shear bearing capacity needs to be improved
[0004] It...

Abstract

The invention relates to an assembled prestressed corrugated web occlusion steel girder. The steel girder is formed by assembling two prestressed corrugated steel channel beams through bolts, wherein webs of the steel channel beams are in occlusion and butt joint with each other. Each prestressed corrugated steel channel beam consists of a top flange, a web, a bottom flange, a prestressed cable, lateral stiffening ribs, anchorage devices and beam end plates, wherein the section opening shape of each prestressed corrugated steel channel beam is formed by the top and bottom flanges and the web, the section of the web is in a uniform or non-uniform periodic repeating wave shape, the lateral stiffening ribs are vertically positioned between the two flanges and the web, the beam end plates are arranged on the two ends of the beam and parallel to the lateral stiffening ribs, and the prestressed cable is fixed on the beam end plates through the anchorage devices after being tensioned. The steel girder is an innovative assembled prestressed steel girder which is suitable for assembled steel structural systems and particularly large-span multi-high-level assembled steel structural systems; and compared with a conventional assembled girder, the steel girder has the advantages of light weight, high bearing capability, large span and the like.

Description

technical field [0001] The invention relates to an assembled prestressed corrugated web occlusal steel beam, which belongs to the technical field of building profiles. Background technique [0002] At present, the prefabricated steel structure system is an important direction for the development of the steel structure residential system. A lot of on-site welding is used in the construction of traditional steel structure residential buildings, the construction speed is slow, and the pollution to the environment is serious. The most important thing is that the quality of the welds is not suitable for control, which seriously affects the safety performance of the building. It completely overcomes the shortcomings of traditional steel structure houses. In the prefabricated steel structure system, the on-site assembly of beams and beams is a problem that needs to be studied emphatically. [0003] In the existing prefabricated steel structure system, two channel steels are usual...
