Description

Prefabricated superposed beam

Technical Field

The application relates to the field of building prefabricated parts, in particular to a prefabricated composite beam.

Background

Current composite beams are usually made up of two parts, prefabricated and cast-in-place. The prefabricated components are transported to a construction site after being manufactured in a prefabricated site, two negative-moment longitudinal reinforcements penetrate into the prefabricated component outer-leakage stirrups of the composite beam through supporting or connecting with the column, and then the prefabricated component and the cast-in-place part form a complete whole by in-situ concrete pouring together with the column and the plate, and the prefabricated component has the same mechanical property as that of the conventional full cast-in-place beam. The method can reduce the use of the formwork and effectively reduce the construction waste, thereby reducing the environmental pollution and the resource waste.

The conventional composite beam is usually provided with stirrups, each stirrup is formed by bending a steel bar at one time, the overlapped parts of two end parts are bent into hooks with 45-degree angles, and the overlapped corners of the front stirrup and the rear stirrup are staggered. In use, longitudinal reinforcing bars need to be threaded between the two hooks.

In view of the above-mentioned related technologies, the inventor thinks that there is a phenomenon that when penetrating the longitudinal steel bar, the position between the two hooks is easy to shift, so that the longitudinal steel bar is difficult to penetrate between the two hooks, and the construction is complicated.
