Rock wool sandwich panel is a new type of environment-friendly and safe building material. It solves the problem of rain proof, heat insulation, heat insulation, fire prevention and other manufacturing of large-span roof structure. The existing rock wool sandwich panel is generally of tile buckle connection structure, including the panel and bottom plate made of metal plate, and the core material made of rock wool and bonded between the panel and the bottom plate. The bearing capacity of this sandwich panel is weak, The surface strength deviation is large.
The core material made of rock wool is used for bonding between the panel and the bottom plate. The two sides of the panel and the bottom plate are closely connected by two edge sealing side plates to form a closed frame. One side of the panel is bent upward to form a concealed buckle, and the other side is bent upward to form a buckle edge, which is used for lapping and fastening the outside of the concealed buckle.
The bottom of the tile buckle is bent into a pressing edge, the top of the edge sealing side plate is bent to form the upper connecting edge, and the bottom bending to form the lower connecting edge. The upper connecting edge is covered with crimping, and the crimping is fixed on the outside of the crimping edge. The two sides of the bottom plate are respectively covered and crimped on the outside of the connecting edges under the two edge sealing side plates.
The core material is bonded between the panel and the bottom plate. The panel has corrugated corrugated board structure. The corrugated board structure has good mechanical strength, strong bearing capacity and is not easy to deform.
