    Pneumatic Inflatable Rubber Mandrel For Construction

    Discription


    Inflatable rubber mandrel 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.



    The Performance characteristics:

    1- Design scientific and reasonable used inflatable rubber mandrel, or casting parts, finished product can meet the requirement of design, easy operation, save work, save time, save material.
    2- Have good ageing resistance performance and long service life this product use synthetic rubber, natural rubber and strengthen layer vulcanize. Has very good resistance to bulge, flexibility and elasticity, so can satisfy all sorts of work in the conditions of use.
    3- Widely applicable temperature , within the scope 10 °C ~ +90 °C of the material without change.
    4- For building light-duty construction provides favorable conditions to stress hollow concrete component, due to the rubber mandrel, the weight than use stress solid component light 20%, so it can reducing the weight of the upper structure of building, can make the pile foundation short, increase span, make the construction become simple and safety.
    5- Construction technology is simple, safe, health, use it only need a few simple tools, without special process. Only put the mandrel into negative reinforcement cage, inflate air to achieve work pressure, then pouring the concrete. When the concrete freezing, put gas out mandrel , in thus complete the product component forming, and it not pollute the environment.
