Stone curtain wall

详情

B. Steel skeleton
The columns are made of **0**0*4 hot-dip galvanized square steel pipes, the beams are made of L*0*4 hot-dip galvanized angle steel, and M8**0 stainless steel bolts are used. The aluminum alloy hangers are bolted to the beams. The stone is positioned by slotting the upper and lower parts, and epoxy resin AB glue is used for stone installation. The rear buried plate is made of hot-dip galvanized steel plate.
The beams are arranged throughout the length to improve stability. The angle steel spans the columns and is welded or connected to the angle steel by M6 stainless steel bolts to achieve reliable connection on the columns. The stone slabs and beams are connected by hangers. The requirements of temperature difference deformation and building plane deformation are met to the maximum extent.




D. Hanging parts
The styles of hanging parts include T-type, butterfly-shaped, SE aluminum alloy hanging parts, back bolt type, etc.;
The stainless steel hanging parts are connected to the secondary keel, and the dry hanging parts have long round holes that can be adjusted forward and backward, which can effectively ensure the flatness of the granite curtain wall surface;
The granite and stainless steel hanging parts are reliably bonded by modified epoxy adhesive, which has a fast curing speed (initial setting *0min) and has a certain elasticity after curing;
The granite transfers its own weight to the stainless steel hanging parts through a hard PVC pad with a thickness of not less than 3mm to avoid rigid contact;
The connection between the beam and the dry hanging parts adopts M8 stainless steel bolts, which can withstand large loads.




F. Fire protection system
The **0mm thick fireproof rock wool and 1.5mm thick galvanized steel plate are used, with a bulk density of **0Kg/m³, which meet the fire protection requirements.
