Octagonal bridge inflatable mandrel 16 m

Octagonal bridge inflatable mandrel 16 m bridge inflatable mandrel / rubber inflatable mandrel applied to the tunnel, cover, bridges and other projects. Among the most common bridge engineering, both span reinforced concrete hollow slab of precast and cast 10m, or 20m Prestressed Concrete Hollow Slab precast and cast, this rubber mandrel / inflatable mandrel can be as into the hole mold. Rubber mandrel / inflatable mandrel to follow within the aperture dimensions of the various hollow hollow strict custom, before making a smooth and accurate completion of the project. Bridge inflatable mandrel is processed product polymer composite materials, which is the use of high-strength synthetic fiber fabrics withstand the force skeleton, internal and external coating for synthetic rubber adhesive tape protective layer, according to the design dimensions of the high temperature vulcanization process made a multi-standard, multi-size, multi-shaped inflatable rubber pressure, according to the bridge after different sizes, inflated to the pressure standards for cement casting, such as the initial setting of cement grade, drain the gas in the mandrel, the mandrel Pull out the store until the next reuse. Has a high compressive strength, good flexibility and strong tightness, after filling into the air, to replace the original steel, wood mold, such as mold, balloon mold can be used repeatedly, is a New bridge construction to reduce costs and increase the speed of concrete products engineering supporting products, the use of different spans, different shapes, different sizes of bridge engineering commonly used models. Nene bridge mandrel price balloon mold rubber balloon mold making Chia principle balloon inflation pressure molded hollow deck inflatable mandrel price / octagon adjustable balloon / bridge inflatable mandrel manufacturers / beat slab with inflatable rubber mandrel find Hebei Zhengda plant, processing bridge inflatable mandrel hollow octagonal deck adjustable balloon inflatable mandrel inflatable craft with double pressure of 0.02MPa, bridge inflatable mandrel is the best tool for precast hollow simple deck. Applicable span of about 10m, prestressed concrete hollow slab bridge at about 20m.
