Manufacturing method of assembly type prefabricated superposed beam with steel structure connection joints

Abstract

The invention discloses a manufacturing method of an assembly type prefabricated superposed beam with steel structure connection joints. The manufacturing method comprises the following steps that first, main structures, located under the top face of a concrete part, of a superposed beam reinforcement cage and the steel structure connection joints are manufactured; second, the main structures of the steel structure connection joints are connected to the ends of the superposed beam reinforcement cage; third. A formwork is erected, then concrete is poured, and the concrete part of the prefabricated superposed beam is formed; fourth, the formwork is disassembled, and then the parts, protruding the top face of the concrete part, of the steel structure connection joints are welded on the top face of the main structures of the steel structure connection joints. The prefabricated superposed beam manufactured by the method enables the structure of beam column connection joints to be simple, and construction is convenient. According to the prefabricated superposed beam, under the loading effect, the steel structure connection joints can deform and absorb energy first, has good ductility under the earthquake load effect, and is suitable for being applied and popularized to a construction site.

Description

technical field [0001] The invention relates to a method for manufacturing a prefabricated composite beam, in particular to a method for manufacturing an assembled prefabricated composite beam with steel structure connecting nodes. Background technique [0002] In order to reduce resource consumption and strengthen environmental protection, my country has adopted relevant policies to stimulate the development of housing industrialization, and compiled the "Green Building Evaluation Standard" (GB / T50378-2006), vigorously promoting the application of green buildings. The "Green Building Evaluation Standard" advocates that buildings should maximize energy conservation and environmental protection throughout their life cycle, so that the structure can achieve the goal of "less resource consumption and less environmental impact". Under this premise, the superimposed structure has been greatly popularized and applied in engineering because of its superior working performance, ener...

Problems solved by technology

However, the problem of joint connection is a technical problem. At present, reinforced concrete composite beams and concrete columns need a large number of steel bars to connect at the joints. The joint structure is complex and difficult to construct.
