Fabricated prestressed honeycomb web steel beam

Abstract

The invention relates to a fabricated prestressed honeycomb web steel beam, which is formed by two prestressed corrugated web steel channel beams assembled through a bolt, wherein each prestressed corrugated web steel channel beam is composed of an upper flange, a web plate, a lower flange, a prestressed cable, an anchor gear, and a beam end plate, wherein the section opening of each prestressed corrugated web steel channel beam is composed of the upper flange, the lower flange and the web plate; the section of each web plate forms an even or uneven periodic repeated waveform; the beam end plates are vertically connected with the upper flanges, the web plates and the lower flanges, and are arranged at two ends of each prestressed corrugated web steel channel beam; and the prestressed cable passes through the web plates and the beam end plates, and is fixed on each beam end plate by the anchor gear after being tensioned. The planer arrangement disclosed by the invention forms the honeycomb shape; the optimal result can be obtained in the aspect of overall carrying capacity of a member; the fabricated prestressed honeycomb web steel beam is an innovation-type fabricated prestressed steel beam suitable for a fabricated steel structure system, especially a large-span and multi- and high-rise fabricated steel structure system. Compared with the traditional fabricated beam, the fabricated prestressed honeycomb web steel beam has the advantages of light dead load, high carrying capacity, large span and the like.

Description

technical field [0001] The invention relates to an assembled prestressed honeycomb web steel girder, 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 usually used ...

AI Technical Summary

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 can be seen that the effect of using traditional steel components in the fabricated steel structure system is not very satisfactory, which not only affects the mechanical performance of the components, but also consumes a large amount of steel, resulting in unnecessary waste
