AI Technical Summary

Technical Problem

During construction, the matrix arrangement of many concentrated power casings makes it difficult for wooden formwork to process holes, resulting in the inability to turnover and use of the formwork, deformation of the holes, concrete outflow and hollowness, affecting the density and appearance quality.

Method used

A unit-type annular airbag sealing device is adopted, including rubber plates, airbags, air pipes and rubber strips. By combining the formwork and airbag inflation, the position of the sleeve is limited and the surface quality of the concrete is ensured.

Benefits of technology

It realizes flexible adjustment of formwork according to different construction conditions to ensure the quality and density of concrete pouring, solves the problem of formwork support in the concentrated outlet parts of multiple casings, and is suitable for the construction of next processes such as waterproofing.

Abstract

The present invention relates to the technical field of casing reservation in construction projects, and specifically is a unit-type annular airbag plugging device and construction method. It comprises a rubber plate, an airbag is arranged in the middle of the outer side of the rubber plate, casing holes are arranged relatively in the middle of the rubber plate and the airbag, four air pipes are arranged in a matrix on the side of the airbag away from the rubber plate, and a rubber strip is arranged at the outer edge of the outer side of the rubber plate. The unit template can be selected according to the required number of casings, which is convenient for flexible adjustment for more construction conditions. The air pipe closest to the air pump in different directions can be selected as the air inlet according to the actual situation, which is more convenient for construction. After the airbag is inflated, it is close to the casing to generate friction, limit the position change of the casing, ensure the surface quality of the concrete, solve the problem of template support at the concentrated exit part of multiple casings, and ensure the quality and density of concrete pouring, which is conducive to the construction of the next process such as waterproofing.
