Embodiment 1

[0034] refer to figure 2 , a steel-concrete composite beam, which mainly includes a reinforced concrete part 2 for compressive resistance and a steel member part 3 for tensile resistance, and the steel member part is made of a steel plate. The reinforced concrete part 2 is an inverted U-shaped section, and the steel plate part and the reinforced concrete part 2 are connected by bolts. The long steel bars 13 connecting the embedded bolts are arranged between the screw rods to connect to each other.

Embodiment 2

[0036] A construction method for a steel-concrete composite beam: first make an inverted U-shaped mold, put steel bars into the mold and fix it, then pour concrete into the mold to make a U-shaped reinforced concrete member, and set the pre-buried in the concrete Screw rod 5, and finally weld the steel plate to the embedded connector or put the steel plate on the screw rod and tighten it with nuts to form a steel-concrete composite beam. Steel-concrete composite beams connected to walls ( Figure 5 ), the composite beam is placed on the wall body of the wall, and the beam and the beam are connected with steel bars protruding from both ends of the beam. A certain gap is left between the beam and the beam, and crushed stone concrete 8 is poured into the gap.

Abstract

The invention discloses a steel-concrete combined beam, comprising a reinforced concrete part for resisting pressure and a steel component part for resisting pulling force, wherein the reinforced concrete part is a reverse U-shaped section; reinforced bars extend out a certain distance from two ends of the beam for connection; and the steel component part is positioned on the bottom of the combined beam, and forms a whole with the reinforced concrete part through weld joint connection or bolt connection. The combined beam can improve the seismic resistance of the structure, increase the structure ductility, and accelerate the construction progress, thus being a steel-reinforced concrete combined beam with relatively lower engineering cost and convenient construction.

Description

technical field [0001] The invention mainly relates to a building structural component and a construction method thereof, in particular to a steel-concrete composite beam and a construction method thereof. Background technique [0002] Reinforced concrete structures have the advantages of convenient materials, good economy, and skilled construction techniques, and are widely used in our country. However, due to its heavy weight and large inertia, the seismic performance is not good. And because of its long construction period, it is not conducive to the developer's capital turnover. Moreover, the current reinforced concrete structure requires a lot of labor. my country's industrial structure is changing from labor-intensive to technology-intensive, and the salary level of labor is getting higher and higher. If the current construction mode is still adopted, the developer will Need to invest more cost. Steel structure is also a structural form that is widely used in my coun...
