Abstract

The invention discloses a prefabricated steel truss concrete composite structure assembly type superposed beam and a manufacturing method thereof, and relates to the field of building construction. The prefabricated steel truss concrete composite structure assembly type superposed beam comprises an assembly type steel truss and an anti-crack reinforcement cage, wherein the assembly type steel truss comprises a steel skeleton upper cross beam, a steel skeleton lower cross beam I and a steel skeleton lower cross beam II; the end parts of the steel skeleton upper cross beam and the steel skeletonlower cross beam I are connected into a whole through a connecting plate I; a plurality of steel skeleton supporting crosses and a plurality of connecting plates II are connected between the steel skeleton upper cross beam and the steel skeleton lower cross beam I; and the assembly type steel truss is installed in the anti-crack reinforcement cage, and the assembly type steel truss and the anti-crack reinforcement cage form an integrated structure through concrete. According to the prefabricated steel truss concrete composite structure assembly type superposed beam and the manufacturing method thereof, pollution and construction periods of a construction site can be reduced, the influence on the construction period and quality caused by an outdoor climate change method is reduced, and recycling can be realized through multiple construction technologies.

Description

technical field [0001] The invention relates to the field of building construction. Background technique [0002] In the past few decades, my country's construction industry has flourished, which has improved people's living environment and promoted the growth of the national economy. Faced with the continuous rise of labor prices in my country today and the gradual improvement of people's awareness of energy conservation and environmental protection requirements, the construction industry is facing increasing pressure from international competition. In order to improve the core competitiveness, a new industry model - prefabricated buildings came into being. [0003] Prefabricated components are the basic materials of prefabricated buildings, including all prefabricated concrete components, such as beams, slabs, walls, columns, balconies, stairs, canopies, etc. [0004] The beam is one of the very important components of the building. The existing prefabricated composite b...
