Description

Technical Field

[0001] The invention belongs to the technical field of decoration and furnishing, and in particular relates to a positioning member for controlling installation deformation of a marble decorative panel and an installation method. Background Art

[0002] At present, in the construction of indoor and outdoor decoration of building projects, the dry hanging installation and paving construction methods are generally adopted for the wall, column and floor of marble or granite veneer panels, or artificial veneer panels, which is also an extremely important process in decoration construction.

[0003] Traditional dry hanging is to make grooves on the side of the stone and install it on the base steel frame with metal hangers; or to make holes on the back of the stone and install back bolts before hanging it on the base steel frame. The commonly used laying method is to use cement slurry containing construction glue to stick natural marble or natural granite veneer, or artificial stone veneer on the wall column surface; or to use adhesive to stick natural marble or natural granite veneer, or artificial stone veneer on the wall column surface. In order to highlight the indoor and outdoor decoration effects of the building, the designer selected natural marble veneer panels with a bending strength standard value of <7MPa, water absorption rate>0.5, length ≥800mm, and width ≥600mm, or natural granite or other stone veneer panels with a bending strength standard value of <8MPa, water absorption rate>0.5, length ≥800mm, and width ≥600mm, especially gray and black stone. Such stone veneer panels will bulge, bend and deform when the temperature and humidity of the environment change alternately, and when soaked by rain and snow, the dry-hanging or pasted stone veneer panels will crack after local stress concentration. The high stone veneer panels are prone to fall off after deformation, causing quality safety accidents that may cause human injury. The stone veneer panels laid on the ground will be hollow and cracked, and will break and be damaged after being stepped on, so they need to be dismantled and reworked, causing quality accidents in the decoration project. The stone veneer panels with smaller local deformation also need to be polished and then treated with crystal surface. Polishing will cause environmental pollution and increase costs. As seasons change and temperature and humidity change, stone veneers will continue to deform and there will continue to be quality and safety risks. Summary of the invention
