Partition air bag device for building engineering construction

The utility model relates to the technical field of constructional engineering equipment, and discloses a partition air bag device for constructional engineering construction, which comprises an air bag body, an inflation valve for inflation and deflation is arranged at the top of the air bag body, and two fixing blocks are symmetrically and fixedly mounted at positions, corresponding to the inflation valve, of the air bag body. And clamping grooves are formed in the upper wall faces of the two fixing blocks correspondingly, and pull rings are movably connected into the two clamping grooves in a clamped mode correspondingly. According to the air bag, when the air bag body needs to be taken out after concrete pouring is completed, a worker can take out the pull rings in the two clamping grooves, and due to the fact that the pull rings are arc-shaped blocks, the worker can hold the pull rings in the hand after taking out the pull rings and then lift the pull rings upwards to achieve the effect of taking out the
