Single-face overlapped Z-shaped prefabricated part joint

Abstract

The invention discloses a single-face overlapped Z-shaped prefabricated part joint. The single-face overlapped Z-shaped prefabricated part joint comprises upper wall body vertical steel bars and upperwall body ladder bars, wherein the upper wall body vertical steel bars are arranged on the vertical inner sides of the upper wall body ladder bars; upper wall body prefabricated concrete is arrangedon the outer sides of the upper wall body vertical steel bars and the upper wall body ladder bars; additional connecting steel bars are arranged in the middles of the inner sides of the upper wall body ladder bars; the single-face overlapped Z-shaped prefabricated part joint is overall in a Z shape, in the abovementioned way, during assembly type construction, prefabricating can be conducted, andtherefore close splicing connection is achieved; in the abovementioned way, a formwork is not needed, the joint is overall in the Z shape, and the connecting position is effectively prevented from formwork expansion; during prefabricating, the joint is prefabricated into a whole in a factory, in the abovementioned way, the binding work of the steel bars on site is reduced, and therefore the laborintensity of personnel is relieved; and when the joint is connected with an external beam, due to the fact that the overall Z shape is provided with a notch, fixed connection with the exterior is facilitated, and therefore connecting and using are facilitated.

Description

technical field [0001] The disclosure relates to the technical field of prefabricated buildings, in particular to a single-sided superimposed Z-shaped prefabricated component node. 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] In prefabricated buildings, the practice of exterior walls is relatively complicated. The prior art has the following disadvantages: for the external wall with edge components cas...

AI Technical Summary

Problems solved by technology

[0004] The purpose of this disclosure is to provide a single-sided superimposed Z-shaped prefabricated component node to solve the problem that the steel bars of the edge components of the outer wall in the existing prefabricated building proposed in the background art need to be bound at the construction site, and the outer walls need to be External scaffolding and external formwork, and the problem of expansion of external wall nodes
