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 and the amount of steel required for the web are large, and its shear bearing capacity and buckling resistance are relatively low. Low
There are gaps between the assembled concrete wings and there is no effective restraint between adjacent concrete wings, which affects the force transmission between the plates, and then affects the overall function of the floor

Abstract

The invention relates to an assembly type prestress honeycombed ribbed web plate composite beam. The composite beam is formed by two prestress corrugated web plate and ribbed channel steel composite beams which are in butt joint and are assembled through bolts. Each prestress corrugated channel steel composite beam consists of an upper wing edge, a web plate, a lower wing edge, a reinforced concrete wing plate, a profiling steel plate, a prestress rope, transverse stiffening ribs, anchors and beam end plates; the section mouth profile of each prestress corrugated channel steel composite beam consists of the upper and lower wing edges, the profiling steel plate, the reinforced concrete wing plate and the web plate; the section of each web plate is in an even or uneven periodically repeated waveform; a honeycombed web plate is formed after jointing the two web plates. The composite beam is beneficial to integral assembly of the beam plates to comprehensively improve industrial production level of residences, and also has the advantages of light self weight, high bearing capacity and large span.

Description

technical field [0001] The invention relates to an assembled prestressed honeycomb-shaped ribbed web composite beam, which belongs to the technical field of building profiles. Background technique [0002] Prefabricated steel structure system is an important direction for the development of steel structure residential system. In order to better realize modularized integrated design, standardized production and prefabricated construction and installation, beams and floors are often combined as a whole as an assembled unit to speed up the degree of industrialization. When assembling floors, the assembly of composite beams and composite beam parts becomes a very critical issue. [0003] In the existing prefabricated steel structure system, two channel steels are usually used for assembly, and the two channel steel webs are butted and connected by bolts to form a prefabricated H-shaped steel. At the same time, the concrete wing part of the composite beam, Joints form a patchwo...
