Prefabricated concrete composite shear wall based on PBL connection

Abstract

The invention discloses a prefabricated concrete composite shear wall based on PBL connection. The prefabricated concrete composite shear wall comprises a longitudinal shear wall, a transverse door type shear wall and a transverse window type shear wall. The prefabricated concrete composite shear wall has the beneficial effects that shear wall components are prefabricated in a factory, all connection positions adopt dry type connection joints based on PBL, the connection ductility is good, the bearing capacity is large, the anti-seismic property is good, field wet operation is completely abandoned, installation is easy and fast, and the advantages of saving resources, protecting the environment and reducing pollution of the fabricated building technology are brought into play to the maximum extent; concrete materials are adopted, durability is good, installation is convenient, circulation can be achieved, and the prefabricated concrete composite shear wall is suitable for projects with the long construction period and high requirements for durability of temporary houses of the projects; and the center of the wall is subjected to lightweight treatment, and the circulation cost is reduced.

Description

technical field [0001] The invention relates to a composite shear wall, in particular to a prefabricated concrete composite shear wall based on PBL connections, and belongs to the technical field of construction engineering applications. Background technique [0002] The application of prefabricated technology in middle and low-rise buildings is mainly reflected in temporary buildings, light steel villas, etc. Steel structure systems and wood structure systems are more widely used, and concrete structure systems are relatively less used. [0003] Prefabricated steel structures and prefabricated wood structures have the advantages of convenient assembly in terms of structural systems, but their obvious shortcomings of high cost, poor durability, poor waterproof and fireproof performance, and high maintenance costs limit their development. For projects with a long construction period, the durability of existing steel structure temporary buildings does not meet the requirements...

AI Technical Summary

Problems solved by technology

The existing technology mainly has the following two problems: 1. The connection process of structural nodes is generally complicated, and there are all-directional connection joints and a large number of nodes in the components. The connection method is often realized by grouting sleeves or setting post-casting belts at the nodes. The wet connection method seriously affects the appearance of components and the convenience of installation, and brings more difficulties to design and construction

2. The shear wall components are heavy, and the transportation cost of the components is high

3. The existing technology is mostly aimed at permanent buildings, which cannot achieve the goal of turnover, and the resource utilization efficiency is low. Based on this, this application proposes a prefabricated concrete composite shear wall based on PBL connection
