Prestressed stainless steel metal rod connectors OUR ADVANTAGES: 1. Qualified Joint Supplier in Nuclear Power Plant 2. China National Standards Drafting Unit of Rubber Joint Introduction of metal rod connectors metal rod connectors are also known as metal bellows, metal spiral tube and concrete filled tube, anchor bolt with a corrugated tube. Metal spiral tube is made of high quality steel strip after rolling waves, volume tube forming, bite and cut made into circular and oblate corrugated pipe. Because now prestressed concrete structures are used more and more on the building, and prestressed corrugated pipe is required by the prestressed concrete structures. Application of metal rod connectors metal rod connectors used in Bridges, multi-storey factory building, parking lot, office buildings, apartment buildings, stadiums and other large buildings. In modern architecture, has been developed countries such as Britain, France, the United States and Japan are widely used, its light wall thin, strong rigidity, not broken, do not leak slurry, due to the double wave has obvious concave and convex tube in vitro table, steel tube juncture place to tight pressure pattern, firmly not tripping, the strong grip of contact with the concrete after pouring, and concrete forming a complete one, to enhance the seismic performance of structure. Its good function, compared with the general solid tablet, it is light weight, large span, the deflection is small, no column cap, good security, low comprehensive cost, thus increasing the architectural headroom, increase the use and sales area, with the domestic existing ordinary beam slab structure, solid flat slab of unbonded prestressed concrete floor, save steel 5% to 7%, saving concrete amount 10% - 10%, save water, electricity, air conditioning, elevators, vertical external decoration cost 5% to 15%, and has the effect of sound insulation, heat insulation, give owner brought considerable economic benefits.
