What is the point hanging of stone and what is the difference between it and dry hanging?

The difference between point hanging and dry hanging is that:

1, point hanging does not need to punch holes in the stone, but dry hanging needs to punch holes in the back and side of the stone.

2. The point is supported by the angle code, and the dry hanging is to hang the stone with iron wire or copper wire.

3. The point hanging method can be carried out under the condition that the original structure is a concrete wall and the space requirement is limited, and there is no relevant requirement for dry hanging.

Stone hanging means that the original structural wall is not a steel skeleton, but supported by an angle code, and the stainless steel pendant for fixing stone is directly installed on the angle code. When the original structure is a concrete wall and the space requirement is limited, this method can be adopted, but it must be approved by the designer and Party A. ..

Dry hanging of stone refers to the construction technology of using cement nails and iron wires (or copper wires) to open holes on the back and side of stone, hanging stone with iron wires or copper wires, and grouting behind stone. Supported by angle steel fixed on the wall, then fixed with stainless steel pendants not less than 5mm thick at the bottom and upper part of the stone, and sealed with marble glue, also known as dry hanging.

Extended data:

Dry hanging (English name: dry-hang) refers to the abbreviation of a hanging construction method that uses metal pendants to hang decorative materials firmly on the structure to form a veneer.

Slotted dry-hung curtain wall

Through professional grooving equipment, grooves are accurately machined on the edge of the porcelain plate, the pendant is buckled into the grooves, and the porcelain plate is fixed on the keel through connectors.

Shortcomings of slotted porcelain curtain wall

1, which requires a higher thickness of porcelain plates. Generally, porcelain plates are not less than 15mm thick.

2. When grooving, the edge is easy to collapse and the loss is large.

3, need to install steel keel, increase the bearing capacity of the building, increase the cost.

4, insulation layer should be installed separately, insulation layer installation and curtain wall installation cross construction, there are security risks.

5. The stress mode of the plate is point support, which has poor seismic performance and low safety factor.
