  As shown in FIG. 2, the water blocking apparatus 10 of the present invention shown in FIG. 1 is mainly installed in an opening 8 such as a building provided with a pair of rising portions 7 and 7 from one (outdoor side) to the other. The water blocking material 1 is to prevent the infiltration of water to the indoor side).

  The water blocking device 10 has a connecting portion 2 and a connected portion 3 to which the connecting portion 2 is connected. In the present embodiment, as shown in FIG. 1, the water blocking device 10 is connected to the lower end of the water blocking surface material 1. While the part 2 is provided, the to-be-connected part 3 is provided in the water stop material mounting part 4 embedded on the ground.

  The water blocking surface material 1 is disposed between the pair of rising portions 7 and 7 as shown in FIG. 2 and has a width (about 50 to 250 cm) sufficient to cover the opening 8. In addition, it has a height (about 20 to 150 cm) that will not overflow even if the water level rises. The water blocking surface material 1 of the present embodiment uses a panel obtained by extruding a lightly colored translucent resin, and as shown in FIG. 3, a plurality of partition walls between a pair of surface materials 1 a and 1 a By forming (horizontal partition 1b, vertical partition 1c, and diagonal partition 1d), a large number of hollow portions 1e penetrating in the width direction of the water blocking surface material 1 are formed. As described above, by forming a large number of hollow portions 1e by the horizontal, vertical, and diagonal partition portions 1b, 1c, and 1d, the water blocking surface material 1 has a light-weight honeycomb structure (hollow structure). The effort required to carry and install the In addition, by making the water blocking surface material 1 translucent, it is released from the feeling of blockage at the time of installation, and the water level can be easily confirmed from the water intrusion side and the opposite side (indoor side) It will be as well.

Although various thermoplastic resins such as polyvinyl chloride, polyacryl, polyolefin and polyester can be used as the material resin of the water blocking material 1, among them, polycarbonate resins which are a kind of polyester are particularly preferably used. The polycarbonate resin has a good balance of strength, moldability, cost and the like, and can manufacture a high quality water blocking material 1 at a relatively low cost. An ultraviolet absorber and a light stabilizer can be contained in such a water blocking material 1 made of such polycarbonate to improve the weather resistance.
In addition to the synthetic resin as described above, the material resin of the water blocking material 1 can also be formed of FRP, metal or the like, and the material is not particularly limited.

  As shown in FIG. 1, a connection portion 2 is provided at the lower end of the water blocking surface material 1 having the above-described configuration. As shown in FIG. 3, the connecting portion 2 is formed in a convex shape having a substantially elliptical annular cross section formed integrally with the water blocking surface material 1, and the length of the lower end of the water blocking surface material 1 and It is continuously formed with substantially the same length.

On the other hand, the to-be-connected portion 3 is formed in a substantially oval open annular concave shape in which the convex shape of the connecting portion 2 is fitted, and the to-be-connected portion 3 is the water-stopping material attached portion 4. It is integrally formed with the water blocking material attached portion 4 over the entire length.
In addition, although the said connection part 2 and the to-be-connected part 3 are integrally molded with the water stop surface material 1 and the water stop surface material to-be-attached part 4, the separate connection part 2 and the to-be-connected part 3 You may attach to the material 1 and the water blocking material mounting part 4 later.

  The thickness t of the connecting part 2 (the maximum lateral width of the connecting part 2) is formed to be larger than the dimension w of the opening of the connected part 3 as shown in FIG. Therefore, the thickness t of the connecting portion 2 is usually obtained by simply pressing the connecting portion 2 of the water blocking surface material 1 against the connected portion 3 of the water blocking surface material attached portion 4 from the upper side to the lower side. Because it is larger than the dimension w of the opening of the connected part 3, the connecting part 2 and the connected part 3 are not connected (can be slide inserted from the side and can be connected), and it is said that the workability is excellent hard. Therefore, in the present embodiment, the water blocking surface material 1 is simply directed from the upper side to the lower connected portion 3 by making the connecting portion 2 and the connected portion 3 elastically deformable and recoverable. The connection part 2 and the to-be-connected part 3 are connected only by pressing.

That is, as described above, since the connecting portion 2 is integrally molded with the water blocking material 1 made of polycarbonate or the like as a material resin, the connecting portion 2 is also formed of the same material resin. As well known, such material resin is elastically deformable and recoverable, and in addition to that, the connecting portion 2 of the present embodiment is formed in a hollow shape as shown in FIGS. Since the wall thickness thereof is about 0.3 mm to 1.5 mm in order to facilitate elastic deformation, elastic deformation is more likely to occur. Further, similarly to the connecting portion 2, the to-be-connected portion 3 is also formed in a hollow shape. Therefore, when the connecting portion 2 of the water blocking surface material 1 is pressed against the connected portion 3 of the water blocking surface material attached portion 4 below, not only the connecting portion 2 but also the connected portion 3 starts to be deformed, and the thickness t of the connecting portion 2 Is smaller than the dimension w of the opening of the connected portion 3, the thickness t of the connecting portion 2 is narrowed and the dimension w of the opening of the connected portion 3 is increased, and the connecting portion 2 and the connected portion 3 are connected It can be done. Then, when the connecting part 2 and the connected part 3 are connected, the connecting part 2 and the connected part 3 are restored and return to the original shape, so the gap between the connecting part 2 and the connected part 3 is completely It disappears, and it is possible to surely prevent the infiltration of water from there.
In addition, that the to-be-connected part 3 is formed in hollow shape means that the water stop surface material to-be-attached part 4 which comprises the circumference | surroundings of the to-be-connected part 3 is formed in hollow shape.

The said water blocking surface material 1 is hold | maintained by a pair of pillars 5 and 5 as shown in FIG. The column member 5 is a rectangular column consisting of a bottom surface, a top surface, and an elevation surface erected in the vertical direction from the bottom surface, and its specific gravity is larger than water, and one (outdoor side) to the other (indoor side) Even if the water comes in, it is considered that it does not move. In addition, holding portions 5 a that hold both end portions of the water blocking surface material 1 are formed on the rising surfaces of the column members 5. The holding portion 5a is formed with concave grooves extending in the vertical direction on the facing surfaces of the pillars 5 facing each other, and the holding portion 5a holds the both end portions of the water blocking surface material 1 to stop the water The water surface material 1 is prevented from moving by water pressure.
The specific gravity of the pillars 5 can be made larger than that of water by forming the pillars 5 in a hollow shape and filling the inside with a filler such as water or earth and sand. Further, the specific gravity of the column member 5 may be smaller than that of water, but in such a case, it is necessary to take a means for fixing the column member 5 to the rising portion 7 or the installation surface.

As shown in FIGS. 1 and 2, on the inner circumferential surface of the holding portion 5a of the pillar 5, the bottom surface (not shown) of the pillar 5, and the elevation surface located on the rising portion 7 side of the pillar 5. , The water blocking member 6 is stuck. The water blocking member 6 is a member having a water blocking layer for improving the water tightness, and as described above, is stuck to a place where water may enter. Although this water blocking member 6 may be attached to the connecting portion between the connecting portion 2 and the connected portion 3, as described above, the connecting portion 2 and the connected portion 3 are firmly connected without a gap. Thus, the possibility of water infiltration is low, and the water blocking member 6 does not necessarily have to be attached.
In addition, the movement of the column material 5 is suppressed more reliably by giving the function (for example, forming an adhesive layer) of temporarily fixing the column material 5 to the installation surface (ground) or the rising portion 7 to the water blocking member 6 You can also

  As described above, the water blocking device 10 having the above-described configuration is mainly installed at the opening 8 provided with the pair of rising portions 7 and 7, and water from one (outside) to the other (indoor) Of water is prevented by the water blocking surface material 1. Next, the construction procedure will be described.

  First, the water blocking surface material 1 and the pair of pillars 5 and 5 are carried out from the storage place, and the pillar 5 having the water blocking member 6 attached to the bottom, the holding portion 5a and the rising surface is made in front of the rising portion 7 Arrange each one. At this time, it is noted that the water blocking member 6 stuck to the rising surface of the column member 5 is disposed in close contact with the rising portion 7. As described above, when the pair of pillars 5 and 5 are arranged in the rising portions 7 and 7 on both sides of the opening 8, both end portions of the water blocking surface material 1 are aligned from above with the holding portions 5 a of the pillars 5. Insert slide. Then, the water blocking surface material 1 is pressed to the connected portion 3 of the water blocking surface material attached portion 4 located below, and the convex connection portion 2 at the lower end of the water blocking surface material 1 is compressed and deformed. The convex connecting portion 2 is inserted into the concave to-be-connected portion 3 while enlarging the opening of the portion 3. Thus, after inserting the convex connecting part 2 into the concave connected part 3, the connecting part 2 and the connected part 3 are restored to the original convex shape or concave shape, whereby the connecting part 2 and the connected part 3 are restored. 3 is securely connected without gaps, and installation of the water stop device 10 is completed.

Note that although the installation of the water stop device 10 according to the above-mentioned procedure can be installed most efficiently, this order is not particularly determined, and may be performed in an order that is easy for the operator.

(4) to compress and deform the convex connecting portion 2 as described above, and expand the opening opening of the concave connecting portion 3 to form the convex connecting portion 2 The concave connected parts 3 are connected. And a pair of pillars 5 and 5 are slid toward the both ends of water stop face material 1 arranged in that way, and water stop face material 1 is inserted in holding parts 5a and 5a of pillars 5 and 5 You may hold it. Thus, the procedure for installing the water blocking device 10 is not particularly limited, but the contact point between the holding portion 5 a and the water blocking surface material 1 between the bottom surface of the pillar 5 and the installation surface (ground), And, only care should be taken to avoid flooding from the contact point between the column member 5 and the rising portion 7.

Therefore, even in the case of elderly people and women who are poor in physical strength, the water blocking device 10 can be installed easily and quickly.

  Further, in addition to making the thickness t of the convex connecting portion 2 larger than the dimension w of the opening of the concave connected portion 3, both the connecting portion 2 and the connected portion 3 are formed in a hollow shape. Since the connecting portion 2 and the to-be-connected portion 3 are connected only by pressing the connecting portion 2 from above onto the lower to-be-connected portion 3 by being able to elastically deform and restore, the connecting operation is also very high. It will be easy. In addition, when the connecting portion 2 and the connected portion 3 are restored to the original shape, the gap between the connecting portion of the connecting portion 2 and the connected portion 3 is completely equal to none, and sufficient waterproofness can be ensured. .
