[0007] Hereinafter, a boundary structure 1 according to an embodiment of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts having the same functions, and duplicated descriptions in each drawing will be omitted as appropriate.

[0008] [Boundary structure configuration] As shown in Figures 1 (a) and 1 (b) , the boundary structure 1 in this embodiment comprises a partition 2 having a gap 20, a waterproof sheet storage section 3, and a waterproof sheet 4 stored in the waterproof sheet storage section 3 so that it can be freely pulled out and rolled up, and is installed on part of the upper side of a concrete wall b erected on the boundary between the site a1 on the home side on which building a is built, and the road a2 adjacent to site a1.

[0009] Under normal conditions, as shown in Figure 1(a), the waterproof sheet 4 is stored in the waterproof sheet storage section 3 of the boundary structure 1, and the partition body 2 is exposed, thereby enhancing the design of the concrete wall b and improving ventilation. On the other hand, in the event of a flood, as shown in Figure 1(b), the waterproof sheet 4 is pulled out from the waterproof sheet storage section 3 to cover the entire surface of the partition body 1, thereby reducing the amount of water flowing into the site a1 through the gap 20 in the partition body 2.

[0010] In the following, the side of road a2 will be described as the "front" and the side of site a1 as the "rear", and "front" and "rear" will be indicated in each drawing. In addition, the height direction of the concrete wall b will be described as "up and down" and the width direction of the concrete wall b will be described as "left and right", and "up and down" and "left and right" will be written in each diagram.

[0011] [Partition structure] As shown in Figures 2 and 3, the partition body 2 is a louver fence having multiple louvers 22 arranged in the vertical direction on the inner projected surface of a frame 21, and is disposed in a mounting recess b1 recessed downward from the upper end of a concrete wall b. The partition body 2 is erected by inserting an embedded bolt b2 embedded in the lower end of the mounting recess b1 into the lower frame 210 of the frame 21 and tightening a nut b3 onto the embedded bolt b2 that has penetrated the lower frame 210, so that the partition body 2 is erected with the lower end of the mounting recess b1 serving as the base b10. The partition body 2 is supported by the front surface of a support pillar b4 erected on the base portion b10 and fixed thereto with a screw b5. As shown in Figs. 2 and 4, the partition body 2 of this embodiment is divided into a plurality of parts in the left-right direction, and each of the partition bodies 2 is provided with a waterproof sheet housing section 3. The partition body 2 is not limited to a louver fence, but may be any structure having the gap 20. Moreover, the partition body 2 is not limited to being divided into a plurality of parts, and may be configured as a single piece corresponding to the range in which the partition body 2 is disposed. Moreover, the waterproof sheet storage section 3 may be provided for each partition body 2.

[0012] [Configuration of waterproof sheet storage section] As shown in Figures 2 and 3, the waterproof sheet storage section 3 is fixed to the front mounting surface of the upper frame 211 of the partition body 2 with screws or the like, and is formed with the same vertical width as the upper frame 211 so that it can be recognized as part of the upper frame 211 when viewed from the front. The waterproof sheet storage section 3 has an opening 30 at the bottom end through which the waterproof sheet 4 is inserted and removed, and a sheet winding device 31 is provided inside. Two sheet winding devices 31 are provided in the waterproof sheet storage section 3 so as to correspond to the two partition bodies 2, and each can independently pull out and wind up the waterproof sheet 4. In other words, by making it possible to independently pull out and roll up the waterproof sheet 4 from each of the two partition bodies 2, the waterproof sheet 4 can be pulled out quickly with one hand and can be smoothly rolled up.

[0013] As shown in Figure 3, the sheet winding device 31 fixes the upper end of the waterproof sheet 4 and rotates to pull out and wind up the waterproof sheet 4. It is supported by left and right shafts in the waterproof sheet storage section 3, and a rotational force is always acting in the direction of winding up the waterproof sheet 4 due to the biasing force of a spring (not shown). In other words, as the waterproof sheet 4 is pulled downward, the sheet winding device 31 rotates in the pulling out direction against the spring force, allowing the waterproof sheet 4 to be pulled out, and when the pulled out waterproof sheet 4 is lifted upward, the sheet winding device 31 rotates in the winding direction due to the spring force, allowing the waterproof sheet 4 to be automatically wound up. Such a sheet winding device 31 not only pulls out the waterproof sheet 4 during a flood, but also rotates in the winding direction by the spring force to automatically store the waterproof sheet 4 when it is pulled out during disaster prevention training or maintenance.

[0014] The waterproof sheet storage section 3 is not limited to a section that winds up and stores the waterproof sheet 4 using a sheet winding device 31, but may also be a section that folds and stores the waterproof sheet 4.In this case, an example of a section that has an opening / closing lid on the waterproof sheet storage section 3 and opens and closes this lid to insert and remove the folded waterproof sheet 4 (not shown).

[0015] [Waterproof sheet composition] The waterproof sheet 4 is a flexible, thin sheet that is waterproof or a flexible, thin sheet that is difficult for water to pass through, formed into a specified shape, and as shown in Figure 3, the upper end side is fixed to the sheet winding device 31 and wound around the sheet winding device 31. A metal end member 5 is attached to the entire lower end of the waterproof sheet 4, and this end member 5 is connected via a connector 50 to a fixing portion 51 fixed to the lower end of the mounting recess b1, thereby maintaining the waterproof sheet 4 in a pulled-out state placed in the partition body 2. The end member 5 has a mounting hole 52 for mounting the connector 50 , and the connector 50 is mounted to the end member 5 through this mounting hole 52 .

[0016] When the waterproof sheet 4 is pulled out and held in place, a slack 40 is provided at the lower end portion, as shown in FIG. 3(b). The slack 40 is provided so that when water pressure acts on the waterproof sheet 4 during a flood, the slack 40 disappears, providing the waterproof sheet 4 with enough room to cover the partition body 2 in close contact therewith. That is, the gap 20 in the partition body 2 can be blocked by using water pressure to eliminate the slack 40 and by tightly covering the partition body 2 with the waterproof sheet 4. The connector 50 may be, for example, a carabiner or a snap hook that allows for quick and easy connection. Other examples of the connector 50 include rope and wire.

[0017] As shown in Figure 4, the left and right ends of the waterproof sheet 4 are guided in their up and down movement when unrolled and rolled up by guide portions 6 (described below) provided on the partition body 2, allowing the waterproof sheet 4 to be unrolled and rolled up smoothly. At both left and right ends of the waterproof sheet 4, there are provided slide portions 41 that are received in the guide portions 6 and slide, and these slide portions 41 are adapted to move up and down along the guide portions 6.

[0018] [Guide section configuration] As shown in Figures 3 and 4, the guide portion 6 has a support recess 60 with its longitudinal direction extending up and down and fixed to the inner prospective surfaces of the left and right frames 212 of the frame 21, and a guide portion main body 61 fitted into the support recess 60. The support recess 60 has a total length spanning the entire length of the inner projected surfaces of the left and right frames 212, and is a molded member with an open inner projected surface, and its outer projected surface is fixed to the inner projected surfaces of the left and right frames 212 by screws. As shown in Figure 4, the support recess 60 has a slip-out prevention portion 62 formed by bending the open ends in the prospective direction so that they face each other, and this slip-out prevention portion 62 holds the guide body 61 within the support recess 60.

[0019] As shown in Figure 4, the guide body 61 is a convex-shaped mold material having a total length spanning the entire length of the support recess 60, and is positioned within the support recess 60 with the narrow side (tip side) of the convex shape facing the open side of the support recess 60, and the wide side is positioned opposite the anti-slip portion 62 of the support recess 60. At the tip of the guide body 61, a fitting recess 63 into which the slide portion 41 of the waterproof sheet 4 is inserted is provided over the entire length of the guide body 61. Since this guide portion 6, with the slide portion 41 of the waterproof sheet 4 encased therein, guides the up and down movement of the waterproof sheet 4, the waterproof sheet 4 can be smoothly pulled out and wound up.

[0020] [Effects of boundary structures] In the boundary structure 1 configured as described above, under normal conditions the waterproof sheet 4 is stored in a waterproof sheet storage section 3 provided in the partition body 2, wound up by a sheet winding device 31, and the partition body 2 is exposed. In this case, since the vertical width of the waterproof sheet storage section 3 is approximately the same as the vertical width of the upper frame 211 of the partition body 2, the waterproof sheet storage section 3 is recognized as part of the partition body 2, the storage sheet storage section 3 is not conspicuous, and good design is maintained. In the event of a flood, the waterproof sheet 4 can be pulled out from the waterproof sheet storage section 3 and the end member 5 can be connected to the fixing section 51 fixed to the lower end of the mounting recess b1 via the connecting device 50, thereby keeping the waterproof sheet 4 covering the entire surface of the partition body 2. At this time, while the waterproof sheet 4 is pulled out and held in place, a slack 40 is left at the lower end portion, so that when water pressure acts on the waterproof sheet 4 during a flood, the water pressure eliminates the slack 40 and the waterproof sheet 4 adheres closely to and covers the partition body 2, thereby sealing the gap 20 in the partition body 2 and preventing water from entering through the gap 20. In other words, the pulled-out waterproof sheet 4 prevents water from entering through gaps during a flood, thereby slowing down the rate at which water flows into the home's property a1 during a flood, thereby buying time to make evacuation preparations within building a.

[0021] The boundary structure 1 in the present invention is not limited to a configuration in which it is provided as part of a concrete wall b, as shown in the example, but may also be configured to surround the entire perimeter of the site b2 with a partition body 2 having a gap 20 in place of the concrete wall b (not shown). Furthermore, the partition body 2 is not limited to various fences having gaps 20, including the louver fence exemplified above, but may be a gate having a gap.

[0022] The above describes in detail the boundary structure of an embodiment of the present invention with reference to the drawings, but the specific configuration is not limited to these embodiments, and the present invention includes design changes and the like that do not deviate from the gist of the present invention.

[0023] Furthermore, the above-described embodiments can be combined by utilizing each other's technologies, so long as there are no particular contradictions or problems in the purpose, configuration, and the like. [Explanation of symbols]
