Assembling type pre-stress honeycombed ribbed web steel beam

Abstract

The invention relates to an assembling type pre-stress honeycombed ribbed web steel beam and belongs to the technical field of a building section bar. The assembling type pre-stress honeycombed ribbed web steel beam is formed by assembling two butt-joint pre-stress ripple web ribbed steel channel beam webs through bolts. Each pre-stress ripple web ribbed steel channel beam is formed by a top flange, a web, a bottom flange, a pre-stress cable, transverse stiffening ribs, anchorage devices and beam end plates. A section die of the pre-stress ripple steel channel beam web is formed by the top flange, the bottom flange and the web; the section of the web is in a uniform or non-uniform periodically-repeated waveform; the transverse stiffening ribs are vertically placed among the two flanges and the web; the beam end plates are parallel to the transverse stiffening ribs and are arranged at the two ends of the beam; and the pre-stress cable is tensioned and then is fixed on the beam end plates through the anchorage devices. The assembling type pre-stress honeycombed ribbed web steel beam disclosed by the invention is a novel assembling type pre-stress steel beam which is applicable to an assembling type steel structure system, particularly a large-span multi-story assembling type steel structure system; and compared with a conventional assembling type beam, the steel beam has the advantages of light self weight, high bearing capability, great span and the like.

Description

technical field [0001] The invention relates to an assembled prestressed honeycomb ribbed 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 usuall...

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
