Prefabricated concrete composite door wall based on PBL connection

Abstract

The invention discloses a prefabricated concrete composite door wall based on PBL connection. The wall comprises a transverse door type shear wall and a longitudinal shear wall connected with the transverse door type shear wall; and the transverse door type shear wall is perpendicular to the longitudinal shear wall. The prefabricated concrete composite door wall based on PBL connection has the beneficial effects that factory prefabrication of shear wall elements is achieved, dry-type connection nodes based on PBL are adopted in all connection positions, connection ductility is good, bearing capacity is large, anti-seismic performance 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 a prefabricated building technology are played to the maximum extent; concrete materials are adopted, so that durability is good, installation is convenient, turnover can be achieved, and the door wall is suitable for projects which are long in construction period and high in requirement for durability of temporary engineering houses; and the central part of a wall body is subjected to lightweight treatment, so that the turnover cost is reduced.

Description

technical field [0001] The invention relates to a composite shear wall, in particular to a prefabricated concrete composite door wall based on PBL connection, and belongs to the technical field of construction engineering application. Background technique [0002] At present, multi-high-rise steel structure residential building technology has attracted much attention from the construction industry. Steel structure houses have a high assembly rate, are green, efficient, and environmentally friendly, and help promote the industrialization of houses and the construction of green residential buildings. However, the steel columns used in traditional steel structure houses, because of their large cross-sections, cause the corners of the columns to protrude into the house, destroying the integrity and applicability of the interior space. It has the advantage of convenient assembly, but its obvious shortcomings of high cost, poor durability, poor waterproof and fireproof performanc...

AI Technical Summary

Problems solved by technology

[0004] 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 a wet connection method to realize the connection at the nodes through grouting sleeves or post-casting tapes, which seriously affects the appearance of components and the convenience of installation. , which brings more difficulties to the design and construction

[0005] 2. The shear wall components are heavy, and the transportation cost of the components is high
