Through professional groove equipment, the edge of the stone is accurately processed into a groove, the hanging piece is fixed in the groove, and the porcelain plate is fixed to the keel through the connector.

Disadvantages of slotted ceramic curtain wall:

1. The thickness of the stone is very high. Generally, the thickness of the porcelain plate is not less than 25mm.

2. Slotting is prone to fragmentation and large losses.

3. In order to improve the bearing capacity of the building and increase the cost, steel keels need to be installed.

4. Insulation should be installed separately. Insulation and curtain wall installation should be cross-constructed, which poses a major safety hazard.

5. The stress mode of the plate is point-type bearing, with poor seismic performance and low safety factor.

3. Back bolt installation of external wall insulation material

Through professional hole opening equipment, the inner and outer large and small round holes are accurately processed on the back of the ceramic plate. Insert the bolt into the hole, screw in the bolt, and then fully expand the bottom of the bolt to match the tapered hole to form a stress-free convex combination. The external wall insulation material is fixed to the keel through the connector.

Defects of post-bolt dry hanging curtain wall:

1. In order to improve the bearing capacity of the building and increase the cost, it is necessary to install steel keels.

2. Insulation should be installed separately. Installation and curtain wall installation should be cross-structured.

3. Safety risks: The stress mode of the plate is point-type bearing, with poor seismic performance and low safety factor.

Characteristics of dry hanging of exterior wall insulation materials:

1. It effectively avoids hollowing, cracking and falling off in the traditional wet bonding process, and significantly improves the safety and durability of the building.

2. It completely avoids the whitening and discoloration of the surface of the traditional wet molding process, which is conducive to keeping the curtain wall clean and beautiful.

3. To a certain extent, it improves the working conditions of construction workers, reduces labor intensity, and speeds up the project progress.
