What are the bridge rubber air bags used for?
Note: when the inner mold of the airbag is used, it is necessary to brush the isolating agent to reduce the pumping resistance. The airbag does not allow the oil to replace the isolating agent. On the one hand, the oil will erode the rubber, and the other oil will contaminate the reinforcement. It is ideal to dilute with soap water as a release agent. Soap and water ratio is about 1:20.
In the use of rubber inflatable mandrel, first check the reinforcement cage wire joint and rolling head not towards the diameter direction bending, so as not to prick core mold, forming
The bridge is a kind of rubber bladder contraction, inflatable rubber bag, Yongsheng bridge hollow board internal mold is used to form the mold cavity concrete, prestressed concrete hollow slab in the mold is simple to use, safe and sanitary, simple operation, time saving, labor saving. The rubber gasbag is inflated for use, easy to use and convenient to remove after use, saves labor time and labor cost, and reduces work intensity.
Open the valve, inflated to the specified pressure, you can close the valve, must not exceed the pressure.
After the concrete is poured, the vibrating bar is vibrated simultaneously from both sides, so as to prevent the core mold from moving to the left and the right. And the vibration bar segment head can not touch the core mold, so as not to wear and tear gas leakage.
