Product Overview:
Inflatable balloon mandrel is a cylindrical rubber balloon expansion and contraction, used to form the cavity concrete member, in producing hollow components, put it in the middle, and fully compressed air, when concrete release airbag of compressed air, capsule or contraction, and can extract capsule from the cavity, it USES a simple, economic and durable, can be soft when not inflatable contraction, Any folding, crimp, inflation after expansion has enough strength to withstand the pressure of concrete, which is incomparable to any traditional metal core mold.
Scope of application:
Rubber core mold is suitable for pumping reinforced concrete components, including piles, roof truss, roof plate column, beam, underground pipe and other components, is widely used in: industrial and mining foundation, railway, highway bridge, bridge and culvert, construction engineering, water conservancy engineering (dock, slipway, dock).
Product form:
Construction practice has proved that the capsule hole pumping process equipment is simple, not only save materials, and has the characteristics of variable shape, can be made into round, oval, rectangle, arch, octagon, quadrilateral, trapezoid and other pipes. Can also be straight holes, change face, etc., can make the building structure into light, thin wall hollow, change the concrete components have been using metal core mold.
Product performance characteristics:
1. Scientific and reasonable design.
The application of inflatable rubber core mold, to the production or on-site casting out of the finished product construction, can meet the design requirements, and simple operation, labor saving, time saving, saving material, etc.
2. Good aging resistance and long service life.
This product is made of synthetic rubber, natural rubber and reinforced layer after vulcanization. It has good anti-rising strength, good elasticity and flexibility, so it can meet the requirements of use under various working conditions.
3. Wide range of applicable temperature.
In the range of -10 ℃ ~ +90℃, the material does not change.
4. It provides favorable conditions for light construction on site.
Prestressed hollow concrete construction, due to the use of rubber core mold, its weight is 20% lighter than non-prestressed solid construction, so reducing the weight of the building superstructure, can shorten the pile foundation, increase the span, site construction is simple and safe.
5. The construction process is simple, safe and hygienic.
The use of rubber core mold, only a small number of simple tools, no special process, as long as the core mold into the steel cage, inflation pressure to work pressure, you can cast concrete, when the concrete initial setting, the core mold after the release of air, you can complete the finished product construction molding, do not pollute the environment.
