Problems solved by technology

[0005] The most common shear connectors in steel-concrete composite beams are studs. Since studs are generally welded to steel beams, they are prone to stress concentration and have poor fatigue resistance, which affects the service life of composite beams.
Studs are mainly used to connect concrete slabs and steel beams, and it is impossible to realize the horizontal connection between two conc

Abstract

The invention relates to a steel-prefabricated concrete composite beam and a manufacturing method thereof. The composite beam includes a prefabricated reinforced concrete slab 1, a prefabricated reinforced concrete slab 2 and an H-shaped steel beam, a prefabricated reinforced concrete slab 1, a prefabricated reinforced concrete slab 2 and an H-shaped steel beam. The steel beams are connected by detachable shear connectors. The invention not only has strong shearing resistance, but also is easy to disassemble.

Description

technical field [0001] The invention relates to a steel-prefabricated concrete composite beam and a manufacturing method thereof. Background technique [0002] In the process of urbanization in my country in recent decades, most of the construction methods are based on on-site manual work, which has problems such as long construction period, low resource utilization rate and large ecological environment damage. In order to establish a sustainable new industrialized building system, the country is vigorously promoting the construction of prefabricated buildings. The prefabricated building has the advantages of high industrialization level, less wet work on the construction site, low material consumption, and can reduce dust and construction waste on the construction site. environmental purpose. [0003] The steel-concrete composite structure makes full use of the advantages of steel and concrete. It is a structural form with optimized performance. It has the advantages of h...
