What's the difference between dry hanging and hanging stones?

The difference between dry hanging and hanging stones;

1. Generally speaking, hanging slate is directly pasted on the slate surface with cement mortar, and dry hanging slate is slotted on the slate surface with iron pendant, marble glue, dry hanging AB glue and various structural adhesives, and then the construction is completed.

2. The cost of dry hanging is higher than that of hanging paste, and the thickness of dry hanging stone is thicker than that of wet paste. If the specifications of the stone are relatively large and the wall height exceeds 2M, it is suitable for dry hanging. Slurry hanging is not easy to operate, grouting is not easy to compact, and it is easy to fall off, which is risky.

2. Dry hanging is better than hanging. Indoor stone plastering is easy to regain moisture, leading to abnormal color on the surface, and indoor stone plastering is easy to return to alkali.

Extended data:

Dry hanging stone is a kind of construction technology of building exterior wall, and the dry hanging method of stone is also called empty hanging method. It is a new construction technology in wall decoration at present. This method is to hang the decorative stone directly on the wall or on the steel frame without grouting and pasting. Its principle is to set the main stress points on the main structure, and fix the stone on the building through metal pendants to form a stone decorative curtain wall.

This technology uses corrosion-resistant bolts and corrosion-resistant flexible connectors to directly hang decorative stone materials such as granite and artificial marble on the outer surface of the building structure, leaving a cavity of 40 ~ 50 mm between the stone materials and the structure. Under the action of wind and earthquake force, the veneer made by this technology is allowed to produce appropriate displacement to absorb part of the wind and earthquake force without cracking and falling off. When the wind-induced earthquake force disappears, the stone will also reset with the structure.
