The inner membrane of the hollow plate airbag produced by Hengshui Dexiang Rubber and Plastic is made of vulcanized rubber and fiber reinforced layers. The product has high tensile strength, elasticity and air tightness. After being filled with compressed air, it can replace the original Wood mold, bamboo mold, steel mold. It is a concrete supporting product that can be reused many times to reduce costs and speed up construction progress.
The inner membrane of the hollow plate air bag is an industrial product and its use is very wide. The following is an introduction to one of them: hollow plate air bag inner membrane has different names due to different regions or fields of use, such as: hollow plate air bag inner membrane, air bag inner mold, inflatable mold core, bridge hollow plate air bag inner membrane, etc. The characteristics of the air bag inner membrane are low cost, simple use, convenient transportation, and easy storage.
How to use the inner membrane of the hollow plate air bag:
Put the inner membrane of the hollow plate air bag into the mold
Evenly apply the release agent on the surface of the inner membrane of the hollow plate air bag.
Use a rope to pull the inner membrane of the hollow plate air bag into the steel cage with concrete at the bottom and place the inflating mouth of the inner membrane of the hollow plate air bag outside.
Inflation
Open the air inlet valve of the inner membrane of the hollow plate air bag to inflate. Use a pressure gauge to control and monitor the air pressure when inflating.
When the air pressure reaches the operating pressure, close the air inlet valve.
The inner membrane of the special-shaped hollow plate air bag should be inflated alternately until the operating pressure is reached.
D Be careful not to overpressure during use.
Fixing and pouring concrete
When the concrete is vibrated, the inner membrane of the hollow slab air bag will float, so it must be fixed up, down, left, and right. The general diameter is the mandrel stirrup spacing. As the diameter increases, the spacing decreases accordingly.
The method of pouring concrete is basically the same as that of core construction. Pay attention to using high-frequency insertion or ramming rods to vibrate from both sides at the same time to prevent the left and right displacement of the inner membrane of the hollow plate air bag. It is best not to touch the mandrel with the end of the ramming rod.
Formwork removal
When the concrete is initially set, open the valve to deflate and pull out the inner membrane of the hollow plate air bag. The time to remove the formwork depends on the cement number.
Rinse the inner membrane of the hollow plate airbag and test the water. Please take it off and store it so that the inner membrane of the hollow plate air bag can be reused.
