Inflatable turnover high-low grade concrete pouring blocking net air bag and mounting method thereof

Abstract

The invention belongs to the technical field of building construction, particularly relates to an inflatable turnover high-low grade concrete pouring blocking net air bag and an installation method thereof, and provides the following scheme aiming at the problems that in the concrete pouring process, concrete overflowing is likely to happen, the blocking net effect is poor, and the cost input is high. Comprising a reinforced concrete beam and blocking net air bag bodies distributed at equal intervals, a reinforcement cage is arranged on the inner side of the reinforced concrete beam, the blocking net air bag bodies are connected to the reinforcement cage at equal intervals, reinforcing plates are symmetrically arranged on the inner side of the reinforced concrete beam, and the two reinforcing plates make contact with the outer walls of the two sides of the reinforcement cage respectively. The device is easy to use, can flexibly meet the requirements of blocking nets of beams with different cross sections, is easy to operate and apply on site, reduces the site operation difficulty of workers, effectively solves the common quality problem of appearance color difference of high-grade and low-grade concrete pouring, reduces the investment of a traditional fast and easy closing-up steel wire net, reduces the later repair cost, and improves the construction quality.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an inflatable and turnable high-low-marked concrete-casting net-blocking airbag and an installation method thereof. Background technique [0002] With the continuous development of modern buildings, reinforced concrete structures continue to break through new heights, the loads on structural columns and cables are also increasing, and the requirements for concrete strength grades are getting higher and higher. In line with the concept of structural science and economic rationality, the concrete labels at the beam-column joints are often inconsistent when the frame structure is designed, but the structural design and use requirements require the beam-column members to be cast as a whole at the same time to obtain better structural performance. In the actual construction process, when the high- and low-grade concrete is poured, the over-filling of the low-grade concre...

Problems solved by technology

[0003] The traditional construction technology mostly adopts the fast and easy closing net, that is, using steel wire mesh and formwork reinforcement to customize the blocking piece according to the beam section size. high investment
