形成している。FIG. 1 is an overall perspective view showing an example of a stopper according to an embodiment, and FIG. 2 is an overall perspective view showing a stopper according to another embodiment. The stopper 1 has a plurality of elongated rod-shaped members 2 (nine in this embodiment) of the same length arranged in parallel and in a plane at a constant interval, and these are connected at one end by a connecting member 3. They are connected integrally and are formed into a comb shape.

確保することができればよい。The tip end 2t of the rod-shaped member 2 is sharpened to some extent, and is formed of, for example, resin or metal, or a stainless material or the like to prevent rust. The dimension is set to a diameter of 10 mm for resin (or 6 mm for metal) and a length of 500 mm. The shape and dimensions are appropriate, and it is sufficient that the rod-shaped member 2 can be easily inserted into ready-mixed concrete and that the strength can be ensured so that bending does not occur at the time of insertion.

回避するためである。The main purpose of the present invention is that it is formed in a comb shape, and the connecting mode is not the gist. Therefore, as shown in FIG. 2, the connection of the stopper 10 is fixed at the upper end of the rod member 12. The two rod-shaped members (which may be the same as the rod-shaped member 12) 13 and 13 are connected to each other with an interval of, and the upper end portion thereof may be covered with the cover body 14 so as to wrap the connecting member 13. . This cover body 14 can hold the stopper 10 by holding this portion, and avoids a hazard to the worker due to contact of the tip portion 12e or the like when handling the stopper 10.

例と同様である。[How to Use the Stoppers] The stoppers 1 and 10 having the above-mentioned configurations are used by the following working method. As shown in the longitudinal sectional view of FIG. 3, first, the floor surface form 56, the handrail wall form 58 are installed and the reinforcing bars 54 are arranged in accordance with the procedure of the conventional work method. Then, the floor surface concrete mixture 57 is poured and cast into the sectioned area of the floor surface form frame 56. Up to this point, it is the same as the above-mentioned conventional example.

A plurality of the stoppers 1 (or 10) are continuously inserted along the boundary 4 and the bottom 5 in the compartment of the handrail wall form 58. In addition, the stopper 1 is inserted as in the above-mentioned conventional example by using the floor fresh concrete 5
There is no need to wait until 7 is semi-cured.

ン57の方へ移動する。After this, as in the conventional process, the handrail wall raw concrete 60 is poured from the upper opening 59 of the handrail wall form 58. At this time, since the stopper 1 has a comb-like shape, the aggregate such as stones having a predetermined particle size mixed in the fresh concrete is prevented from moving, while only the moisture passes through to the floor surface raw concrete. Move to 57.

When the hardness is 0 and it does not blow out,
Pull out the stopper 1. This pull-out is done on the floor
Since it is not completely hardened and is performed in a soft state, it can be easily performed, and the holes left behind can be easily contracted and the surface can be evened easily.

The following effects are obtained. That is, since the stopper 1 has a comb shape, the movement of aggregates such as stones having a predetermined particle diameter mixed in the fresh concrete is prevented. Therefore, it is possible to prevent the swelling of the floor surface raw concrete due to the jetting, which has occurred in the conventional method.
【0023】また一方、液体分は、棒状部材の間を通過

生コンの硬化を促進させることができる。On the other hand, since the liquid component passes through between the rod-shaped members and moves toward the floor surface raw concrete, the hardening of the handrail wall raw concrete can be promoted.

ることができる。Furthermore, since the handrail wall ready-mixed concrete can be poured and placed without waiting for the floor surface ready-mixed concrete to be semi-hardened, it is possible to simultaneously harden these and make a unitary structure. Also, favorable results can be obtained. Moreover, since there is no waiting time, the working time can be shortened.
