Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a prefabricated assembled wall component and a construction method thereof. Background Art

[0002] Prefabricated wall components are concrete wall panels pre-made in factories, such as single-panel wall panels, sandwich composite wall panels and light steel keel composite wall panels, etc. They are used in prefabricated buildings and are widely used in industrial and civil buildings, especially residential buildings. With the acceleration of my country's urbanization process, prefabricated buildings have ushered in new development opportunities.

[0003] Referring to the existing Chinese patent with publication number CN221721980U, a prefabricated assembled wall assembly component is disclosed, including a first wall and a second wall panel, one side surface of the first wall and the second wall panel are fixedly connected with a splicing strip, the surface of the splicing strip is provided with a longitudinally long installation groove, the other side surface of the first wall and the second wall panel away from the splicing strip is provided with a rectangular groove, the size of the rectangular groove matches the splicing strip, and the inner wall of the rectangular groove is fixedly connected with a positioning block.

[0004] The above-mentioned prefabricated assembled wall composite component, by providing a splicing strip and a rectangular groove at the joint of two adjacent assembled wall panels, can use the splicing strip and the rectangular groove to splice and combine the two wall panels, which can not only achieve the effect of seamless splicing, but also can splice and install the two wall panels without raising the wall panels, thereby facilitating the installation of indoor partition walls inside the building, and the operation is convenient, which is beneficial to the construction efficiency. However, the above-mentioned prefabricated assembled wall composite component still has some shortcomings, such as: the anti-slip limit block is inserted into the limit socket on the inner wall of the installation slot to achieve rapid splicing and fixation between the two wall panels. Only by fixing the limit block in the limit socket, when the wall panel is subjected to a strong impact, the connection stability of the limit block is particularly fragile, and the connection part is prone to deformation, which affects the stability of the structure and poses a safety hazard.
