1, back groove type, which is made by processing the back groove specially, then processing a dovetail groove on the back of the porcelain plate according to the design size, and then fixing the special anchor on the porcelain plate by mechanical and adhesive methods, so that the porcelain plate is connected and installed on the base surface through pendants.

2. Back bolt type, which can also be set by special drilling equipment. The back of the porcelain plate is processed into a tapered hole with a large inside and a small outside according to the design size. At this time, the screw can be screwed in, so that the bottom of the anchor bolt expands completely and cooperates with the tapered hole to form a stress-free convex fit. Then, the hook can be fixed on the porcelain plate through the anti-slip nut, and then installed on the base surface.

3. Buckle porcelain, the upper and lower sides of the porcelain plate have grooves, so it can be installed on the base surface through pendants. Fix the dry-hung tiles on the wall with bolts, then weld and fix the vertical keel and the horizontal keel, and then fix the stainless steel tenon on the horizontal keel with bolts. Grooved granite tenons are stuck on the back of vitrified brick and fixed on stainless steel tenons according to the design arrangement requirements, which avoids the shortcomings such as hollowing, cracking and falling off caused by wet sticking process.
