Introduction to rubber airbags

Rubber airbag, also known as concrete prefabricated hollow slab rubber inflatable core mold, bridge inflatable core membrane, rubber internal mold, is a type of expandable and shrinkable internal mold that utilizes the high polymer properties of rubber and high-strength fiber cloth vulcanization. Mainly used for the pouring and forming of pre tensioned and post tensioned concrete beams in highway bridges. It is also adopted by culvert drainage projects. After the rubber airbag is filled with compressed air, it expands and expands to meet its cross-sectional design requirements. The inflation pressure is determined according to the manufacturer's identification and cannot be overpressure inflated. It is easy to use, economical and durable, and can be reused nearly a hundred times. It is soft and shrinks when not inflated, and can be folded or curled freely. After inflation and expansion, it has sufficient strength to withstand the pressure of concrete. It can replace the original wooden, bamboo, and steel molds, and can be reused multiple times. It is a concrete product supporting products that reduce costs and accelerate construction progress.
