Stainless Steel Back Bolt Screws
With the development of social economy and the improvement of people's quality of life, higher requirements are put forward for the quality of the living environment, which promotes the development of the curtain wall pendant decoration industry. With the widespread use of stone, ceramic board and terracotta panels on the curtain wall, higher requirements are put forward for the safety performance and construction technology of the curtain wall. The back bolts are made of high-quality stainless steel materials, and the stone back bolts have corresponding anchor bolts for different thicknesses and specifications of the stone back bolts. Stainless steel back bolts are made of high-quality stainless steel materials, and there are corresponding anchor bolts for different plate thicknesses and specifications.
About the product advantages of stainless steel back bolts:
1. The back bolt expansion body is a continuous structure surface. When the expansion body expands, the diameter of the upper end decreases and the diameter of the lower end increases. The back bolt expansion body changes from a cylindrical surface to a conical surface with equal surface areas.
2. The radius of the conical surface of the expansion body is equal to the radius of the conical surface of the bottom-cutting hole of the stone, and the two surfaces form a concentric surface meshing state, which is a stress-free meshing state.
3. Since the expansion body of the stone back bolt and the bottom hole of the stone are meshed with concentric conical surfaces, the meshing area is correspondingly increased. In similar products, under the same stress condition, the meshing pressure is reduced, which effectively increases the load between the stone and the back bolt. ability.
