。One of the latest architectural structures is a hollow slab, which has a hollow section created by embedding a pipe made of a thin spiral metal plate into a reinforced concrete slab. This hollow slab has the advantages of being able to construct long spans, lowering floor heights, halving the number of columns, having excellent sound insulation, eliminating ceiling construction, and allowing the hollow part to be used as a duct. .
第８図は従来の中空スラブの形成状態を示す図である。FIG. 8 is a diagram showing how a conventional hollow slab is formed.

による中空部を内蔵する中空スラブＡを形成する。Referring to the same figure, when forming the hollow slab A, the pipe B for forming the hollow part is fixed on the concrete panel C, which is a temporary frame, using a tool, then concrete is poured, and the installation is done using a tool. Remove the wedge E attached with the pipe, remove the concrete panel C, and remove the hollow part forming pipe B.
A hollow slab A having a built-in hollow part is formed.
第９図は第８図に示す中空部形成用バイブＢを仮枠であ

する取付は具りの支持棒Ｃの先端を切断する。For this installation, after placing the vibrator B on the receiving part of the tool, tie the wire G to the locking part a to fix the placed vibrator B and prevent it from lifting up when pouring concrete. We are trying to prevent this. Further, after pouring the concrete, removing the wedge E and removing the concrete panel C serving as a temporary frame, the tip of the support rod C of the attachment tool protruding from the lower surface of the formed hollow slab is cut off.
ところが、この切断部分は、形成された中空スラブの下
面に露出することになる。However, this cut portion is exposed on the lower surface of the formed hollow slab.
