Shanxi Luliang 8-angled precast hollow slab airbag 760 * 710 solid and durable 8-angled precast hollow slab airbag internal mold is adopted Natural rubber 、 synthetic rubber The high temperature vulcanization process of reinforced strong fiber cloth is a kind of multi specification, multi shape and multi size rubber gas mold, which has good compressive strength, good elasticity, strong air tightness and tear resistance. After being filled with compressed hollow, it can replace the original steel mold, wood mold, bamboo mold and other molds, and can be used repeatedly. Compared with the traditional steel mold, it is simple to operate, easy to install, convenient to disassemble, and flexible in turnover. It is a new type of concrete products supporting products to reduce the cost of bridge construction and improve the speed of engineering. It uses different spans, different shapes Bridge works of different specifications. When using, it is only necessary to evenly coat the core mold with the release agent, and then use the rope to pull it into the reinforcement cage. When the inflation pressure reaches the working pressure, concrete can be poured. When the concrete is initially set, the core mold can be deflated and pulled out to complete the molding of finished components.
8 It is recommended that the length of the air bag of the angle precast hollow slab should be 1 m longer than the beam length. If the air bag is at the angle of 30 ℃, it should be 1.5 m longer than the beam length. In this way, it is convenient to drag, fix and construct.
