Description

A kind of prefabricated wall panel hanging node and installation method thereof

technical field

The invention relates to a wall panel hanging node, in particular to a prefabricated wall panel hanging node and an installation method thereof, belonging to the technical field of prefabricated decoration integrated walls.

Background technique

With the country's vigorous promotion of prefabricated buildings and green buildings, standardized, integrated and modular prefabricated decoration has also developed rapidly. Prefabricated decoration is a decoration method in which factory-produced parts and components are assembled and installed on site, mainly including integrated wall system, dry construction method floor (ground), integrated kitchen, integrated toilet, separation of pipeline and structure, etc. As one of the commonly used materials for the whole house wall and ceiling, the integrated wall is also the riser of the whole-house quick installation mode. Because the integrated wall has many advantages such as environmental protection, integration, fast installation, and beautiful decoration, it has become the preferred choice for prefabricated decoration. Material.

Ordinary integrated wall system adopts horizontal keel (spacing 500 ~ 600mm), interior wall decorative board adopts 10mm thick composite calcium silicate decorative board (standard board 900mm width), the side of decorative board is vertically slotted, aluminum alloy I-shaped card bar is fixed. Reinforcement boards are added inside the partition walls that require load-bearing parts such as wall-mounted air conditioners and TVs. The quick-installation wall system uses a T-shaped plastic expansion plug to fix the horizontal keel on the structural wall. The T-shaped expansion plug has a leveling function. The side of the composite calcium silicate decorative panel is vertically slotted, and the aluminum alloy I-shaped clip is fixed. This kind of interior wall decorative panel with integrated wall has no direct connection measures with the wall, and only relies on the vertical slot on the side of the decorative panel and the I-shaped clip to be fastened. During construction, the interior wall decorative panel is prone to bulging and loosening. , broken at the fixed place, etc. The measures in the prior art to solve these problems are to apply structural glue on the horizontal keel, and paste the interior wall decorative board on the horizontal keel, which cannot meet the environmental protection requirements.

In addition, the general interior wall decorative panels are connected by clearance fit. In addition, the strength of the wall panel materials such as calcium silicate and PVC is general, and it is prone to certain deformation during installation, which may easily cause problems such as large gaps and looseness of the interior wall decorative panels after installation.
