A plastic-aluminum board erection joint structure for outer wall installation
Technical Field
The invention relates to the technical field of building structures, in particular to an aluminum-plastic plate mounting and connecting structure for mounting an outer wall.
Background
The aluminum-plastic composite board is a composite material which is formed by processing a chemically treated coated aluminum plate serving as a surface layer material and polyethylene plastic serving as a core material on special aluminum-plastic board production equipment. The unique performance of the aluminum-plastic composite plate determines the wide application of the aluminum-plastic composite plate: it can be used for renovation of building exterior wall, curtain wall board and old building, decoration of indoor wall and ceiling, advertisement signboard, display rack and purification dust-proof engineering, belonging to a new type building decorative material. At present when installation plastic-aluminum board, mostly direct mount is on the building outer wall, because consider the strong wind in the wall body outside, environmental impact such as rainwater impact, consequently often attach special attention to stability and joint strength when the installation, but can cause the installation degree of difficulty to increase like this, workman's aerial operating time is longer, construction cost is higher, be unfavorable for whole construction cost's control, and because wall body and plastic-aluminum board can take place expend with heat and contract with cold phenomenon in the external environment, make the plastic-aluminum board of direct mount on the wall body have connection structure easily to receive the risk of destruction. In view of this, we propose an aluminum-plastic panel installation and connection structure for exterior wall installation.
