c. taking out the cushion blocks edge by edge, plugging the cushion blocks into the inflatable template, inflating the inflatable template, and replacing the cushion blocks with the inflatable template;
d. fixing the fixed edge of the inflatable template with the floor slab by using screws;
e. pouring a concrete column;
f. and after the concrete of the concrete column is completely solidified, removing the concrete column template and the inflatable template to complete the pouring of the concrete column.
The structure for pouring the concrete column by adopting the inflatable template fixed with the floor slab comprises the floor slab arranged beside the concrete column to be poured, column inner steel bars for pouring the concrete column are bound on the top surface of the floor slab, and a column template for pouring the concrete column is erected around the column inner steel bars; an inflatable template is filled between the column template and the floor slab, an entity fixing edge is arranged on one side of the inflatable template, the entity fixing edge and the inflatable template are connected into a whole, a screw hole is arranged on the entity fixing edge, a pressing plate covers the entity fixing edge, and the entity fixing edge of the inflatable template is fixed on the floor slab after the screw penetrates through the screw hole on the pressing plate and the entity fixing edge.
In the structure, the inflatable template is a hollow airbag type structure which is made of wear-resistant rubber and can be inflated and expanded.
In the structure, the hollow part of the inflatable template is of a right-angled trapezoid hollow structure, and an inflating nozzle is arranged at the hollow part of the inflatable template.
In the structure, the inflating nozzle is an air nozzle for an automobile tire.
By adopting the technical scheme, compared with the prior art, the invention adopts the mode that the inflatable template replaces the cement mortar crack plugging or the batten pressing during the formwork erecting in the prior art, the inflatable template can fill the whole column range after being inflated, and is matched and connected with the floor slab and the column template in a tight thread joint, thereby effectively solving the technical problem that concrete slurry flows out from the bottom gap of the column template during the concrete pouring in the prior art, and further improving the pouring quality. The inflatable formwork has good sealing performance and certain strength, reduces slurry leakage, has good concrete forming quality, reduces cost, is environment-friendly and pollution-free, and basically does not need to be cleaned after pouring is finished. The novel LED lamp has the advantages of strong universality, reasonable splicing of various sizes, high repeated utilization rate, environmental friendliness and no pollution. The labor cost is saved, the operation is simple and convenient, the construction period is short, and the concrete forming quality is good.
