Assembly type corrugated web holding-on H shaped steel composite beam

Abstract

The invention relates to an assembly type corrugated web holding-on H shaped steel composite beam which is assembled by two corrugated steel channel composite beam webs in a holding-on butt joint mode through bolts. The fracture surface of each corrugated steel channel composite beam is composed of an upper flange, a lower flange, one web, a profiled steel plate and a reinforced concrete plate. The fracture surface of each web is in even or uneven wave shape repeated periodically; the flanges are steel plates, and one side in the length direction of each flange is a corrugated curve which is same as curves of the webs in shape; the upper flange is in parallel with the lower flange, the webs are vertically located between the flanges, the corrugated curve sides of the flanges are connected with the corrugated fracture surfaces of the webs, and the webs and the flanges are connected by the adoption of single-face fillet weld. The reinforced concrete wing plate, the profiled steel plate and the upper flange are fixed through studs. The assembly type corrugated web holding-on H shaped steel composite beam is an innovation-type composite beam which is suitable for a full assembly type steel structural system and has the advantages of saving rolled steel and being high in bearing capacity and good in stress performance compared with a traditional assembly type steel beam and a traditional composite beam.

Description

Technical field [0001] The invention relates to an assembled corrugated web occluding H-shaped steel composite beam, which belongs to the technical field of building profiles. Background technique [0002] The prefabricated steel structure system effectively overcomes the disadvantages of traditional steel structure residences such as large on-site welding, slow construction speed and difficult control of construction quality. It is an important direction for the development of steel structure residence systems. In the prefabricated steel structure system, beam and beam assembly on site is a problem that needs to be studied. [0003] Compared with steel beams, composite beams have the following advantages: they can use the compression effect of the composite floor concrete on the steel beams to increase the effective height of the beam section, improve the flexural rigidity and bearing capacity of the steel beams, thereby saving steel and reducing cost; Compared with the reinforce...

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. 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.

[0005] 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
