Description

Technical Field

[0001] The utility model relates to the technical field of high and low grade concrete interception, in particular to a high and low grade concrete interception air bag. Background Art

[0002] As a core material in the construction industry, concrete's quality directly impacts the structural safety and durability of building projects. With the advancement of construction technology, the use of concrete has evolved from a single grade to a combination of multiple grades to meet the load-bearing and functional requirements of different structural components. During the concrete construction process, interception technology for high- and low-grade concrete has emerged, aiming to effectively separate concrete of different strength grades through physical or chemical means. Early interception technologies primarily relied on disposable materials such as quick-close mesh. While these technologies achieved a certain degree of interception, their limitations became increasingly apparent.

[0003] The existing high and low grade concrete interception technology has the following main shortcomings: First, disposable interception materials such as quick-and-easy closing nets do not need to be dismantled in the later stage, but cannot be used in a turnover manner. They are one-time investments with high costs. Quick-and-easy closing only involves tying wire mesh on the steel bars for interception settings. However, due to the limited airtightness and strength of the wire mesh, after the concrete is poured, under the action of the lateral pressure of the concrete, the isolation net is broken by the concrete, and the high-strength grade concrete flows to the surrounding beams and slabs, resulting in concrete waste and increased costs. The chiseling and processing of the interface has also become a headache for construction workers in the project, and the quality of concrete construction cannot be guaranteed.

[0004] Secondly, the partition airbag is a cylindrical flexible air mold that can be inflated and deflated. After inflation, it plays the role of separating high-grade and low-grade concrete. However, the integrity between ordinary airbags is poor, and the interception effect on high-grade and low-grade concrete is very unsatisfactory, especially at the junction of high-grade and low-grade concrete. The stability and sealing of the airbag are difficult to guarantee, resulting in concrete mixing and affecting the overall performance of the structure.

[0005] Given the limitations of existing technologies, this solution aims to address key technical issues in the process of intercepting high- and low-grade concrete. Specifically, it is necessary to develop a new type of interception airbag that not only has excellent sealing and stability to adapt to different construction environments and concrete fluidity requirements, but also requires material recyclability and reuse to reduce project costs. Furthermore, the design of the new airbag should fully consider construction convenience and efficiency, simplify the construction process, increase construction speed, while ensuring concrete construction quality and avoiding structural safety hazards caused by incomplete interception.

[0016] A large-flow inflation and deflation nozzle is set on the top of the vertical airbag to improve construction efficiency.

[0017] The intercepting airbag is divided into left airbag, right airbag and middle airbag according to the airbag setting position.

[0019] In order to correspond to beams of different sizes, the length of the vertical airbag is set to five specifications: 80cm, 100cm, 120cm, 140cm, and 160cm.
