Description of the Related Art The hollow slab method is a method applied when forming the floor surface of each floor of a building, in which a plurality of hollow slab pipes are floated in parallel after the floor formwork is erected. It is widely used as a method for constructing a lightweight floor surface with high efficiency by placing a cement slurry on top of it and burying the hollow slab pipe, and after solidifying, removing the floor form from the concrete surface. It has been generalized. In this construction method, a large number of hollow slab pipes are regularly supported in a hollow position on the formwork surface in a floating state in order to provide a hollow portion in the floor surface, and even when the cement slurry flows in, the pipes Don't let the movement push you
It must be fixed immovably in that position. Therefore, in the hollow slab construction method, supporting and fixing of the hollow slab pipe is an essential procedure, and since a large number of pipes are arranged in parallel, the workability of fixing the pipes to a predetermined hollow position depends on the overall schedule of this construction method. Will be an important factor that will affect the.

に繋がる。In all of the prior arts cited above, the workability of supporting and fixing the hollow slab pipe in the hollow position on the floor surface form F is improved, and each has its own effect. Although it is recognized that it was raised, it is a fact that there are still problems when implementing it locally.
Whatever the most urgent requirement for improving workability and safety is that the hollow slab pipe can be supported and fixed only by the work of the upper part of the floor form, in any form. If it can be realized, improvement of workability, especially shortage of construction personnel is a serious issue, and labor saving of local work will be directly realized, which will lead to the long-awaited technical contribution.

固定が可能なのかは疑問の余地が残る。From this point of view, all the prior arts are premised on the joint work in which workers are arranged above and below the floor surface form F, and both respond to each other. In particular, for work below the floor formwork F, considering the spine of the worker, the arms of the floor formwork F surface (which becomes the ceiling surface) cannot reach the floor, so work on high places on the scaffold is strong. However, the work itself is cumbersome and inefficient, and work with an unstable and unreasonable posture is difficult to achieve in terms of occupational safety, and there is a possibility that it may lead to a result that violates the safety-first slogan. Japanese Patent Publication No. 55-12951 aims to prevent accidents by working only on the floor, but it is doubtful that the pipe can be fixed unless there is work above and below the floor. There is room for it.
