Description

An assembled prefabricated concrete wall panel

Technical Field

The utility model relates to the technical field of assembled buildings, in particular to an assembleable prefabricated concrete wall panel.

Background Art

Precast concrete wall panels are reinforced concrete panel components processed in precast plants (yards) or construction sites for building assembly, referred to as wall panels or sidings. Using precast concrete wall panels to build assembled large-panel buildings can improve the degree of factory-based and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, and shorten the construction period.

The prefabricated plug-in fence described in publication number CN210918501U has fast assembly speed, reasonable structure, good fixing effect and can be reused; the fence can simplify the construction process, be flexible to install, and standardize the production of the fence while ensuring normal use. However, the prior art still has defects:

1. The prior art uses simple splicing interfaces and splicing blocks for splicing. Although it can be quickly installed, this type of assembly method is not firm and is easily impacted, causing the splicing to break, the wall to move, or even collapse, and has poor safety performance.

2. The prior art fixes the prefabricated wall panels through the base, but there is no connection mechanism between the bases, which makes it easy for the bases to be misaligned during assembly, causing the assembled wall to tilt. In addition, the base is large in size and occupies more space. Once poured, it is no longer convenient to move.
