Description

Dry-hanging structure of stone curtain wall installed with back buckle and tight seam

【Technical field】

The invention relates to a wall decoration layer composed of regular stone components, in particular to a back-tight locking type dry-hanging structure of a stone curtain wall installed with tight seams.

【Background technique】

At present, stone components are used as the decorative layer for the wall decoration of construction projects in our country. Large pieces of natural stone are fixed on the surface of the main structure of the building, which has a noble, gorgeous and solemn visual effect, and is widely used. Its construction method can be divided into wet operation and dry operation. Dry operation is convenient for construction, the wall surface will not return to alkali, and the quality is more guaranteed, so it has been rapidly promoted. When stone curtain walls are used in high-rise buildings, often because the height of the building exceeds 100 meters, the curtain wall stone panels at the height of the floor will be displaced and deformed due to the vibration and displacement of the building structure under the action of earthquakes and wind. At this time, the stone curtain wall will lose its original stability, and cracks, gaps or fragments will appear. In severe cases, the stone slabs of the stone curtain wall will be broken and fall off quickly, causing safety accidents.

Prior art fails to solve such problems. For example, the Chinese patent "ZL98228353.9 stone curtain wall pendant" and the Chinese patent "CN01267672.1, Windproof and earthquake-resistant pendant for stone curtain wall" both propose a pendant structure, which is composed of L-shaped pieces, T-shaped pieces and fastening connectors. After being connected with the T-shaped piece, it is fastened on the horizontal keel fixed to the wall. One end of the T-shaped piece is provided with an ear piece, and the ear piece is inserted into the strip-shaped groove on the two adjacent stone plates up and down for connection. Adjacent stone slabs. Inlay joints between adjacent stone slabs. This pendant can solve the dry construction of the stone curtain wall, greatly reducing the decoration cost. But there are the following disadvantages: (1) The stone is installed on the horizontal keel through a pendant, which usually adopts two keel frames, that is, the horizontal keel is the main keel, and the horizontal keel has to be fixed on the wall through another keel. The auxiliary keel consumes a large amount of steel, which is not economical and environmentally friendly; (2) There is no windproof and earthquake-resistant structure, and a T-shaped piece connects the upper and lower stones at the same time. Resist the invasion of earthquake waves or strong typhoons; (3) The superposition of the lateral distance of L-shaped pieces, T-shaped pieces and transverse keels results in a large distance between the wall and stone, requiring a large installation space.
