Single-sided superimposed L-shaped prefabricated part joint and construction method

Abstract

The invention relates to a single-sided superimposed L-shaped prefabricated part joint and a construction method. The single-sided superimposed L-shaped prefabricated part joint comprises upper wall vertically-distributed steel bars and upper wall ladder bars, wherein the upper wall vertically-distributed steel bars are arranged on the vertical inner sides of the upper wall ladder bars, and the upper wall vertically-distributed steel bars are buried in upper wall prefabricated concrete. The single-sided superimposed L-shaped prefabricated part joint is integrally prefabricated into an L shape,so that the single-sided superimposed L-shaped prefabricated part joint can be prefabricated respectively during fabricated construction, tight splicing connection is realized, an outer template is not needed, and manual operation is reduced; when the single-sided superimposed L-shaped prefabricated part joint is connected with an external beam, a notch is formed in an end opening of the single-sided superimposed L-shaped prefabricated part joint, so that a reinforcing cage is fixedly connected with the external beam, and the connection and use are facilitated; the L-shaped design is small, so that the standard production is easy; and a wall which is connected with the prefabricated joint can be prefabricated for longer, so that the overall cost is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of prefabricated buildings, in particular to a single-sided laminated L-shaped prefabricated component node and a construction method. Background technique [0002] Because prefabricated buildings have the characteristics of green construction, environmental protection and high efficiency, they have been vigorously developed in recent years. The state has also issued a number of policies such as the "Guiding Opinions on Vigorously Developing Prefabricated Buildings", and strives to make prefabricated buildings account for 30% of the new construction area by 2025. So far, comprehensively promoting the development of prefabricated buildings has become the top priority of the construction industry in various provinces and even the whole country. [0003] The prior art has the following defects: in prefabricated buildings, the way of external walls is relatively complicated. Most of the edge component...

AI Technical Summary

Problems solved by technology

[0005] The purpose of this disclosure is to provide a single-sided laminated L-shaped prefabricated component node and a construction method to solve the problem that the steel bars of the edge components of the outer wall in the existing prefabricated building proposed in the above background technology need to be bound at the construction site, and the external Walls require external scaffolding and external formwork, and the connection between prefabricated nodes and prefabricated beams and other components is more convenient, the prefabricated nodes are smaller, easier to produce, and reduce the overall cost
