Inflatable rubber formwork( construction formwork used for making hollow concrete formwork ) is a kind of cylinder bag that can expand, shrink, used to form concrete component of cavity, in the process of manufacturing hollow component, put it in the middle, and filled with compressed air, make the capsule expand, as the concrete component solidification then can empty gas from the cavity, pulled out the capsule. It is easy to be used, convenient and durable, is soft and can fold, curly, contraction when it isn't inflate, it have the enough strength to withstand the pressure of concrete when it is inflated, this is incomparable with any traditional template. it is used in reinforced concrete members, including stake, roof, roof board column, beam, building, water conservancy project (shipyards, slipway, dock). Construction practice proves that Inflatable rubber mandrel is simple, not only save materials, and has a shape characteristics, it could be round, oval, rectangle, vaulted, trapezoidal pipeline, etc. Also you can make a straight hole, etc, can make a building structure light, thin wall hollow, change the concrete performance have been used rigid characteristic template situation.
