Assembly type prestress honeycombed web composite beam

Abstract

The invention relates to an assembly type prestress honeycombed web composite beam. The assembly type prestress honeycombed web composite beam is assembled by two prestress corrugated web steel channel composite beam bodies through bolts. Each prestress corrugated web steel channel composite beam body is composed of a reinforced concrete wing plate, a profiled steel plate, an upper flange, one web, a lower flange, a prestressed cable, an anchor and a beam end plate. The fracture surface of each prestress corrugated steel channel composite beam body is composed of the reinforced concrete wing plate, the profiled steel plate, the upper flange, the lower flange and the webs. The fracture surface of each web is in even or uneven wave shape repeated periodically, and each prestressed cable penetrates through the webs and the beam end plate and is tensioned and then fixed to the beam end plate through the anchor. The plane of each web is arranged to be honeycombed to obtain the optimum effect in overall bearing capacity of the component, and the assembly type prestress honeycombed web composite beam is an innovation-type assembly type prestress section steel composite beam which is suitable for an assembly type steel structural system and particularly suitable for a large-span multi-story or high-rise assembly type steel structural system. Compared with a traditional assembly type beam, the assembly type prestress honeycombed web composite beam has the advantages of being light in self weight, high in bearing capacity, large in span and the like.

Description

technical field [0001] The invention relates to an assembled prestressed honeycomb web composite beam, which belongs to the technical field of building profiles. Background technique [0002] The prefabricated steel structure system effectively overcomes the shortcomings of traditional steel structure housing, such as large amount of on-site welding, slow construction speed and difficult quality control, and is an important direction for the development of steel structure housing systems. In the prefabricated steel structure system, the on-site assembly of beams and beams is a problem that needs to be studied emphatically. [0003] Compared with steel beams, composite beams have the following advantages: the compression effect of composite floor concrete on steel beams can be used to increase the effective height of beam sections and improve the bending stiffness and bearing capacity of steel structural beams, thereby saving steel and reducing construction costs ;Compared w...

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.

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
