Abstract

The invention relates to a section beam and in particular relates to a U-shaped steel-concrete composite section beam and a construction method of the section beam. The U-shaped steel-concrete composite section beam is used in the field of steel structure housing construction engineering. Web plates are respectively arranged at two side ends of the upper part of a base plate, wherein transverse stiffening plates and anti-shearing toggle pins are uniformly distributed and respectively arranged at the inner walls of the web plates and the upper part of the base plate; support section slotting top plates are arranged at the left ends and the right ends of the upper parts of the web plates; vertical battening plates are uniformly distributed between the two support section slotting top plates; support brackets are arranged on the outer walls of the web plates; the upper ends of the web plates, the support section slotting top plates and the vertical battening plates are inserted into a concrete beam; a grouting cavity is formed by the base plate, the web plates, the support section slotting top plates and the vertical battening plates; concrete is added into the grouting cavity. The construction method of the section beam comprises the following steps: manufacturing and processing the section beam in a factory, mounting and constructing the section beam in a field. According to the U-shaped steel-concrete composite section beam and the construction method of the section beam, the U-shaped steel-concrete composite section beam is compact in structure, capable of forming a complete set of industrial, assembling and mechanical processing, guaranteeing the processing quality and accelerating the construction period, easy and convenient in field construction and high in assembly degree.

Description

technical field [0001] The invention relates to a section beam, in particular to a U-shaped steel-concrete composite section beam and a construction method thereof, which are applied in the field of steel structure house construction engineering. Background technique [0002] Reinforced concrete beams are the traditional main force-bearing components of building construction, and have the characteristics of large cross-section, self-heavy weight and long construction period; steel structure beams have the characteristics of high strength, good seismic performance, light weight, recyclable utilization, and convenient construction. It also has the disadvantages of poor fire performance and poor corrosion resistance; the steel-concrete composite beam can take advantage of the advantages of the steel structure and the concrete structure, and increase the strength of the component and improve the ductility of the component under the same amount of steel. It has been widely used t...
