Assembly type ripple web plate occluded steel beam

Abstract

The invention relates to an assembly type ripple web plate occluded steel beam which is prepared from two ripple steel channel beams assembled together through occlusion and butt joint of web plates and through bolts. A cross section mouth of each ripple steel channel beam is composed of an upper flange, a lower flange and one web plate, wherein the cross sections of the web plate form a uniform or nonuniform periodically-repeating waveform, the cross section of ripples of the web plate is a rectangular curve, an arc angle rectangular curve, a trapezoid curve, an arc angle trapezoid curve, a wedge-form curve, an arc angle wedge-form curve or a sine curve, the flanges are steel plates, one edge of each flange in a length direction is a waveform curve with a shape similar to that of the curve of the cross sections of the web plate, the upper flange is parallel to the lower flange, the web plate is perpendicular to and located between the upper flange and the lower flange, the waveform curve edges of the flanges are connected with the ripple cross sections of the web plate, and the web plate is connected with the flanges through single-sided angle welding. The assembly type ripple web plate occluded steel beam provided by the invention is applicable to innovative steel beams in an assembly type steel structure system; and compared with traditional assembly type steel beams, the assembly type ripple web plate occluded steel beam has the advantages of light weight, high carrying capacity and good bearing performance.

Description

technical field [0001] The invention relates to an assembled 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] The steel beams that can be used in the same field include hot-rolled I-beams, hot-rolled H-be...

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

[0007] 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
