Furthermore, the air inlet and outlet valve is arranged at the top of the air mould body, the air mould body is arranged at the position, located at the bottom of the wall body formwork, of the bottom end of the air mould body during construction, the bottom of the air mould body is provided with a convex edge which protrudes outwards, the bottom of the wall body formwork is provided with a groove, the convex edge is exposed, after the poured concrete is solidified, the wall body formwork is disassembled, and the air mould body is taken out from the bottom.
Furthermore, the air inlet and outlet valve is arranged on one side of the bottom of the air mold body, during construction, the air mold body is arranged at the position, located at the top of the wall body, of the top end of the air mold body, and after the poured concrete is solidified, the air mold body is taken out from the top.
Furthermore, the air mould body is cylindrical after being inflated.
By adopting the construction method, the air mould body can be arranged in the template of the concrete wall to be poured, a certain space is occupied in the concrete wall after the air inlet and outlet valve is used for inflating the air mould body, and then the concrete is poured between the air mould body and the template, so that the consumption of the concrete can be reduced. After the concrete is solidified and the air is discharged through the air inlet and outlet valve, the air mould body is reduced and separated from the concrete, and the air mould body is effectively isolated from the concrete by the outer demoulding layer, so that demoulding is convenient.
By adopting the construction method, the consumption of concrete can be greatly reduced, the self weight of the concrete member can be reduced, and the construction cost of construction projects can be reduced. The gas mould body used in the invention has low manufacturing cost, convenient use and repeated use.
