Prefabricated-type steel-profiled steel sheet concrete combined beam

Abstract

The invention discloses a prefabricated-type steel-profiled steel sheet concrete combined beam, which employs steel structure columns or steel-concrete combined columns for supporting. The combined beam includes prefabricated composition boards, stubble steel plates, steel bars on the plate bottom, and a steel beam. An anti-shear connection member is welded to the steel beam. The steel beam is connected with the steel structure columns or steel-concrete combined columns to form a framework structure. The prefabricated composition boards are placed on the steel beam, wherein the stubble steel plates are pre-embedded in four sides of the prefabricated composition boards. Hogging moment steel bars are bidirectionally pre-embedded in the top part of the prefabricated composition boards. In theprefabricated composition boards, the stubble steel plates are welded to the jogging moment vertical-forced steel bars. In adjacent prefabricated composition boards, the stubble steel plates are fixed via bolts. Concrete on the top zone of the steel beam is poured in site, thus forming the complete steel-profiled steel sheet concrete combined beam. The product is low in in-site working load, canachieve non-supporting construction, is high in construction speed and construction quality, and is low in construction operation difficulty.

Description

technical field [0001] The invention relates to a building structure beam, in particular to a prefabricated assembled steel-pressed steel plate concrete composite beam. Background technique [0002] Prefabricated steel structures and prefabricated steel-concrete composite structures are structures in which prefabricated components are the main force-bearing components and are assembled and connected. Steel-concrete composite beams are generally used as horizontal force-bearing members in the two structures, and profiled steel-concrete composite panels are used as the flange plates of composite beams. At present, there are the following problems in the construction of common composite beams: 1. On the construction site, electric welding machines are used to penetrate the profiled steel plate and weld the studs on the steel beam. Second, for the composite slab with temporary support, the temporary support of the construction needs to be removed when the concrete reaches the p...

Problems solved by technology

At present, there are the following problems in the construction of common composite beams: 1. On the construction site, electric welding machines are used to penetrate the profiled steel plate and weld the studs on the steel beam. Second, for the composite slab with temporary support, the concrete needs to reach the predetermined strength before the temporary support can be removed, and the construction speed of the composite beam is significantly lower than that of the steel structure column (steel-concrete composite column)

To sum up, the existing steel-profiled steel plate concrete composite beams have disadvantages such as large welding workload on site, high difficulty in construction operations, and long construction period.
