Then rock wool or foam for heat preservation and heat insulation is filled in the framework. Then, the OSB plates are arranged on two sides of the framework, the moisture-proof breathing paper is laid on the outer sides of the framework, and finally the wooden keel bars and the external wall panels are arranged. In addition to the production and assembly of the steel skeleton being performed in a production shop, the remaining assembly work is often performed on site. The disadvantages are that: the assembly level of wall body assembly is not realized, the construction efficiency is low, and the occupied labor force and the number of equipment are still large.
The heat preservation layers such as rock wool and the like, the OSB board, the breathing paper and the external wall board are assembled in a workshop to form a short integral composite wall sheet, and then all the integral composite wall sheets are transported to an installation site to be assembled to form a long wall body, so that the production efficiency can be greatly improved, the labor force and the occupation of equipment are reduced, and the important original intention of assembly type buildings is realized. However, because the inside and outside sides of the steel skeleton of the finished wall plate are covered and shielded by the assembled component elements, such as the OSB plate, the breathing paper, the external wall plate and the like, the method of directly connecting the connecting steel ribs of the connected composite wall plate by using rivets or self-tapping nails to form the wall body cannot be realized on the premise of not damaging the assembled elements.
Therefore, the cold-formed thin-wall light steel composite wall sheet with the clamping key type connecting structure has the advantages of simple structure, reasonable design, convenience for field installation, firm and reliable connection, easiness in production and processing and low cost.
