  First, the bearing portion 94 formed on the upper surface of the reinforcing column 9 and the second water blocking shaft 6 are fitted. Next, both ends 111 and 112 of the second-stage connecting beam (hereinafter, the same applies to the constituent elements of the connecting beam 110 referred to as “connecting beam 110” to be distinguished from the first-stage connecting beam) are respectively connected to the first ends. It inserts in the insertion part 16B formed in the storage area | region 10, and the insertion part 93B formed in the support | pillar 9 for reinforcement.

  Thereafter, the shafts 113B and 114B of the lock mechanisms 113 and 114 formed on the lower surface of the connecting beam 110 are pushed down to fix the shafts in the axial direction while protruding to the other end.

  Specifically, the shaft portion 113B is fixed in the axial direction while penetrating the opening portion 16b formed in the insertion portion 16B and the opening portion 111a formed in the end portion 111 of the connecting beam 110. Similarly, the shaft portion 114B is fixed in the axial direction while penetrating through the opening portion 93b formed in the insertion portion 93B and the opening portion 112a formed in the end portion 112 of the connecting beam 110.

  Through the mounting operation described above, the reinforcing column 9 is connected to the second water blocking shaft 6, and the connecting beam 110 connects the reinforcing column 9 and the insertion portion 16 </ b> B formed in the first storage region 10. . The connecting beams 100 and 110 reinforce the reinforcing column 9 attached to the back side of the water-stop sheet 4 by being attached to the back side of the water-stop sheet 4 in this manner. Thereby, even if it is a case where water flows toward the near side from the back side in the figure, the tolerance to the water pressure of the water stop sheet 4 can be enhanced.

  As described above with reference to FIGS. 8 to 11, in the water stop device 1 according to the present embodiment, the reinforcing column 9 and the plurality of connecting beams 100 are used. Further, the number of connecting beams 100 to be attached can be switched between two cases (see FIG. 10) and four cases (see FIG. 11). Thereby, the tolerance with respect to the water pressure which the sheet | seat 4 for water stop receives by the flow of the water which goes to the back side from the near side of FIG. 7, for example can be strengthened in steps according to the water level.

  According to the present embodiment described above, the water stopping height can be easily changed according to the amount of water to be infiltrated. Specifically, when water can be stopped by mounting up to the first water blocking shaft 5, the inlet / outlet is closed only by mounting up to the first water blocking shaft 5, and stopped by mounting up to the first water blocking shaft 5. In the case of a height where water cannot be used, the first and second water blocking shafts 5 and 6 can be used to block the entrance / exit.

  In the present embodiment, the case where the water stop device 1 includes two upper and lower water stop shafts has been described as an example, but a configuration including three or more water stop shafts may be used.

  As mentioned above, although embodiment of this invention was described, the said embodiment showed one of the application examples of this invention, and in the meaning which limits the technical scope of this invention to the specific structure of the said embodiment. Absent. Various modifications can be made without departing from the scope of the present invention.
