A construction method of multi-steel beam-concrete composite ultra-flat beam and flat beam

Abstract

The invention discloses a multi-steel beam-concrete composite ultra-flat beam, which includes a steel cage, and one or more parallel and opposite main steel beams are connected inside the steel cage, and two rows of reserved holes are opened on each main steel beam. It also includes a plurality of angle steels, each angle steel passes through the reserved holes to connect multiple main steel beams, two rows of angle steels are connected to secondary steel beams, and concrete is poured on the outside of the reinforcement cage to form a multi-steel beam of the present application ‑Concrete composite ultra-flat beam; it has the advantages of excellent mechanical performance, strong seismic energy dissipation capacity, and simple construction, and is suitable for long-span structures. The invention discloses a construction method of a multi-steel beam-concrete composite ultra-flat beam, and the construction is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a multi-steel beam-concrete composite super-flat beam, and also relates to a construction method of a multi-steel beam-concrete composite super-flat beam. Background technique [0002] Flat beams are beams whose width is greater than or equal to the height of the beam. The composite structure combines the steel structure with the concrete structure, so that the component has good seismic energy dissipation capacity, and at the same time can further reduce the size of the component. The composite flat beam is a structural form that applies the composite structure to the flat beam. . The existing composite flat beams mainly use a combination of a single steel beam and reinforced concrete to form a composite flat beam. However, due to the generally large width of the flat beams, the ratio of steel in the existing composite flat beams is small, which cannot b...

AI Technical Summary

Problems solved by technology

The existing composite flat beams mainly use a combination of a single steel beam and reinforced concrete to form a composite flat beam. However, due to the generally large width of the flat beams, the ratio of steel in the existing composite flat beams is small, which cannot be used well. Advantages of Portfolio Structure

In addition, the demand for composite components with large spans, large volumes and low net heights in today's actual projects is increasing, and the composite ultra-flat beams suitable for this kind of working conditions have the defects of complex construction and long construction period
