What are the operating steps for rubber airbags

1. Rubber airbag injection molding

(1) Before injecting the air into the mold, it is necessary to conduct an on-site interview to check whether the ribbed floor has been damaged or leaked in previous construction projects. This will ensure that the ribbed floor is properly pulled in and avoid any negative impact on product quality throughout the entire process of precast concrete.

(2) After the precast concrete at the bottom of the slab beam is completed, the rubber airbag is threaded into the punched cast-in-place pile by a rope traction rope. The ribbed floor is quite large, and the rope is pulled by a lifting equipment with a fixed pulley as the main guide. The bundled ribbed floor must use white bamboo rope, and galvanized steel wire rope should not be used to immediately touch the air mold to avoid damage to the hollow slab core mold in concrete engineering projects.

(3) When inserting the rubber airbag, attention should be paid to placing the longitudinal hole of the ribbed floor cover upwards to reduce the divergence between the cover and the concrete during pulling.

(4) The length of the rubber airbag is 50cm longer than the slab beam, with a length of 25cm on both sides. In concrete engineering projects, the hollow slab core mold needs to be lifted immediately to ensure a cavity at the intersection with the slab beam end mold, avoiding the risk of slurry leakage and scenery during the entire process of precast concrete, which can cause laborious construction work.

2. The fixation of the rubber airbag remains unchanged

To ensure that the steel reinforcement protection layer of the slab and beam building steel and the level of the inner wall of the slab and beam are closely related to the overall planning and standard requirements, and to avoid the steady growth of the multi ribbed floor during the entire process of pouring concrete, precise positioning hoops are used to fix the building steel with a spacing of 50cm. The mechanical connection between the precise positioning building steel and the slab and beam steel reinforcement is strong, and the diameter level of the precise positioning building steel is the same as that of the inner wall level.

3. Rubber airbag uplifts the air

(1) Immediately after the gas injection, open the intake valve and use the air compressor to lift the air. When uplifting, the pressure gauge should be used to control and inspect the tire pressure standard technical standard technical standard, and the uplifting pressure of the ribbed floor should be determined according to the type. When the tire pressure standard technical standard reaches the operating pressure, the shut-off valve will be closed and the final cut-off will be lifted.

(2) Be careful not to overvoltage when the Qi Xiang is uplifting.

(3) Before the first use of Qixiang, it is exciting to test and accurately measure the sufficient time for each piece to reach the operating pressure. Based on the final setting time of the concrete, the required number of air compressors is created to ensure that the vertical ribs of the slab and the concrete above them are prefabricated before the initial setting of the concrete below them, avoiding the formation of building expansion joints and ensuring the integrity of a slab and beam concrete.
