Fabricated honeycomb web steel beam

Abstract

The invention relates to a fabricated honeycomb web steel beam, and belongs to the technical field of building profiles. The fabricated honeycomb web steel beam is formed by web plates of two corrugated web steel channel beams, which are butted and assembled through a bolt. The section opening of each corrugated web steel channel beam is formed by an upper flange, a lower flange and a web plate; the sections of the web plates form even or uneven periodic repeated waveforms; the corrugated sections are rectangular curves, or arc angle rectangle curves, or trapezoidal curves or arc angle trapezoidal curves, or wedge curves, or arc angle wedge curves, or sine curves; the flanges are plain plates; each upper flange is parallel to each lower flange; the web plates are vertically located between the flanges as a whole; the outer sides of the corrugated curves of the web plates along the length direction are flush to a side boundary of each flange along the length direction; and the web plates are connected with the flanges by a single-side angle welding line. The fabricated honeycomb web steel beam is an innovation-type steel beam suitable for the fabricated steel structure system. Compared with the traditional fabricated beam, the fabricated honeycomb web steel beam has the advantages of light dead load, high carrying capacity, and good mechanical behavior.

Description

technical field [0001] The invention relates to an assembled honeycomb-shaped web steel girder, which belongs to the technical field of building profiles. Background technique [0002] At present, the prefabricated steel structure residential 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 mechanical performance of beams and beams assembled on site is a problem that needs to be studied emphatically. [0003] The steel beams that can be used in the same field include ...

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

[0006] It can be seen that the effect of using traditional steel components in fabricated steel structures 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
