Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated wall panels, in particular to a prefabricated wall panel which is easy to install. Background Art

[0002] Prefabricated wall panels are reinforced concrete wall panels used for house construction that are prefabricated in advance in a prefabrication yard. They are factory-produced, have low costs, reliable quality, and can effectively increase the speed of house construction. They are processed in prefabrication plants or construction sites into reinforced concrete plate-type components for building assembly, referred to as wall panels or siding panels.

[0003] The prefabricated wall panel that is easy to disassemble and assemble described in Publication No. CN212582959U ensures that, when in use, the corresponding prefabricated steel bars on the two prefabricated wall panel bodies are conveniently inserted into the corresponding positioning sleeves through the provided positioning and mounting parts, and it is also convenient to insert the steel bars on the external concrete base into the positioning sleeves in the prefabricated wall panel body to complete the positioning and installation. When disassembling, the prefabricated wall panel body is directly moved to separate the prefabricated steel bars from the positioning sleeves, which is convenient for disassembly and assembly operations. The defect that conventional prefabricated wall panels are inconvenient to disassemble and assemble during installation and use is solved, thereby increasing the workload of the staff and increasing the operation steps, which brings inconvenience to the corresponding staff. However, the prior art still has defects:

[0004] 1. Generally, the upper end of a prefabricated wall is directly fixedly connected to the beam plate, and no second prefabricated wall is connected. This will greatly reduce the lateral load bearing capacity of the entire wall surface. Therefore, it is not practical to set a positioning installation piece on the upper side. In addition, the prior art does not set a fixing mechanism for the splicing of the prefabricated wall panels on both sides, resulting in poor bearing capacity of the wall panels.

[0005] 2. The prior art supports the wall through supporting ribs, but since the supporting ribs are only connected to the wall but not to the ground, the wall is prone to displacement and the fixing effect is poor. Utility Model Content
