Inflatable rubber mandrel, also called inflatable rubber core mold or inflatable rubber formwork, is similar to a marine airbag, but different in usage - that is to form cavities for large reinforced concrete structures including bridge, tunnels, roof, stake, roof board column, beam, building construction, irrigation works and water conservancy projects, etc. In this way, 20% weight of building structure is reduced than those with solid concrete structures.Meanwhile, inflatable rubber mandrels shorten the pipe foundation, increase span as well as provide a simpler and safer construction. |
1.High strength to withstand the pressure of concrete when the mandrel is inflated. 2.Quality synthetic rubber and natural rubber materials make the mandrel durable, long lasting, flexible and elastic. 3.Save materials, time and efforts. 4.Soft to fold, curly, contract and store. 5.Various shapes including round, oval, rectangular, vaulted, trapezoidal, etc. 6.Great resistance to aging and bulge. 7.Wide applicable temperature ranging form 10°C to 90°C. 8.Easy and convenient to operate - only place mandrels into negative reinforcement cage, inflate them to appropriate work pressure, pour concrete and deflate the mandrels until the concrete is solid, then pull the capsule out. |
