The side metal part pressing portion 42 is inclined so that the portion facing the side part metal part 55 at the pressing position is separated from the side part metal part 55 as going outward from the contact part 45 in the left-right direction. In the plan view, only a part of the tip of the side metal part pressing portion 42 comes into contact with the side holding metal part 55. Since the side metal part pressing portion 42 extends in the up-down direction, the contact range of the contact portion 45 is a continuous linear shape without interruption in the up-down direction.

  Next, a procedure for causing the side grip 40 to grip the side of the sheet 20 will be described. FIG. 8 is a diagram illustrating a state in which the sheet 20 is gripped by the side grip 40 in a stepwise manner.

  FIG. 8A illustrates a state in which the lower end of the sheet 20 is gripped by the lower gripper 60 and before the lateral end of the sheet 20 is gripped by the side gripper 40. Indicates the status. As shown in FIG. 8A, first, the end in the left-right direction of the sheet 20 is moved to a position where it is gripped by the side grip 40. Next, the side grip hardware 55 is moved from the standby position to the grip position. As a result, the sheet 20 is sandwiched between the side holding hardware 55 on the outside of the building, the vertical frame ridge 51 and the waterproof rubber 52 on the inside of the building.

  FIG. 8B shows a state in which the side hardware pressing part 42 moves from the standby position to the pressing position. As shown in FIG. 7 (b), the side metal part pressing part 42 is rotated to the pressing position in a state where the side grip metal part 55 is in the holding position.

  In the present embodiment, a guide stopper 57 is provided on the opposite surface of the side gripping metal piece 55 that does not contact the sheet 20. The guide stopper 57 receives the side metal part pressing portion 42 at the gripping position at one end serving as a receiving surface. The other end of the guide stopper 57 protrudes from the side holding hardware 55 and also functions as a guide for the side metal pressing part 42 toward the holding position.

  FIG. 8C shows a state in which the side holding metal part 55 is held at the holding position by the side metal part pressing part 42. As shown in FIG. 8C, the side metal fitting pressing portion 42 moves to the pressing position, and the side grip metal 55 is fixed to the gripping position by pressing the side grip metal 55 from outside the building.

  Next, the engagement of the vertical frame 12 using the wire 25 passed through the upper end of the sheet 20 will be described. FIG. 9 is a diagram illustrating a state in which the upper end of the sheet 20 is engaged with the vertical frame 12 via the wire 25. In FIG. 9, the lower end of the sheet 20 is gripped by the lower grip 60 (see FIGS. 5A to 5C), and the left and right ends of the sheet 20 are gripped by the side grip 40. Are held (see FIGS. 8A to 8C).

  As shown in FIG. 9, the side holding hardware 55 is elongated in the vertical direction. As described above, the side metal fitting pressing portion 42 that holds the side grip metal 55 at the gripping position is also formed to be elongated in the vertical direction as described above, so that the portion that contacts the side grip metal 55 is linear. . That is, the side metal pressing part 42 applies a pressing force to the side grip metal 55 by line contact. When the side metal part pressing part 42 presses the side grip metal part 55 against the inside of the building by line contact, the pressing force applied by the side metal part pressing part 42 becomes uniform in the vertical direction, and the sheet 20 is stopped without a gap. It can be brought into close contact with the tip end surface of the water rubber 52.

  Further, the lower holding hardware 65 of the lower holding portion 60 is elongated in the left-right direction. As described above, the lower holding hardware 65 is elongated in the left-right direction, and is in a state of surface contact with the lower end of the sheet 20. As described above, the lower hardware pressing portion 66 that holds the lower grip hardware 65 in surface contact at the grip position is intermittently arranged, and the grip state of the lower grip hardware 65 is maintained at a plurality of points. Therefore, it is easy to drain rainwater or the like that enters from the outside when the sheet 20 is stored into the gap between the storage frame 11 and the lower metal pressing portion 66.

  One end of the wire 25 is engaged with one vertical frame 12 via a hook fitting 26, and the other end of the wire 25 is also engaged with the other vertical frame 12 via an engagement fitting (not shown). Is engaged. An engaging portion 27 for engaging the hook fitting 26 or the engaging fitting is disposed inside the vertical frame 12, and the wire 25 is stretched in the left-right direction via the engaging portion. Thus, the upper end of the sheet 20 is held at an appropriate position.

  The hook fitting 26 of the present embodiment is configured so that the entire length thereof can be changed, and the tension of the wire 25 can be adjusted.

  FIG. 10 is an enlarged view of a part (a region 100 surrounded by a chain line) of FIG. As shown in FIG. 10, the waterproof rubber 52 extending in the vertical direction and the waterproof rubber 62 extending in the horizontal direction are connected inside the vertical frame 12. The water-stop rubber 52 on both the left and right sides and the water-stop rubber 62 disposed therebetween and extending in the left-right direction form a water-stop line. By forming the water stop line so as to surround the three sides, it is possible to effectively prevent water from entering the inside of the sheet 20 during use. The retaining portions 21 on the left and right sides of the sheet 20 and the retaining portions 22 on the lower side are also continuous at the corners of the sheet 20 and are formed so as to surround three sides. This also prevents the sheet 20 from easily falling out of the gripping position. In the present embodiment, since the left and right retaining portions 21 and the lower retaining portion 22 are formed of flexible ropes, there is no hindrance even when the sheet 20 is folded.

  Next, the center pillar 14 and the support frame 15 will be described. As shown in FIG. 1, the center pillar 14 is a member that holds the seat 20 at the center in the left-right direction. As shown in FIG. 4, the support frame 15 that supports the center pillar 14 is disposed outside the storage frame 11 and on the inside 3 side with an interval between the storage frames 11.

  FIG. 11 is an enlarged front view illustrating a state in which the wire 25 of the sheet 20 is locked to the middle pillar 14. FIG. 12 is an enlarged plan view showing a state in which the wire 25 of the sheet 20 is locked to the center pillar 14.

  As shown in FIGS. 11 and 12, the center pillar 14 has an engaging projection 16 projecting upward at the top. The engagement protrusion 16 includes a shaft portion 17 protruding from the upper surface of the center pillar 14 and a large diameter portion 18 formed at the tip of the shaft portion 17.

  A notch 23 that exposes the wire 25 to the outside is formed in the center of the upper end of the seat 20 in the left-right direction in accordance with the position of the middle pillar 14. The wire 25 exposed in the notch 23 is hooked on the shaft 17 of the engagement projection 16, so that the upper end of the seat 20 is supported at the center in the left-right direction.

  In the present embodiment, the lower end of the sheet 20 is held by the lower holding portion 60 in both the use state and the storage state. The work of fixing the lower end of the sheet 20 shown in FIGS. 5A to 5C is performed when the sheet 20 is first attached to the storage frame 11, when the maintenance of the sheet 20 is performed, or when the sheet 20 is replaced. It is performed when performing, for example. With the structure of the present embodiment, the work of replacing the sheet 20 can be easily performed without using a tool. For example, when it is desired to dry the sheet 20 without hindering the passage, the sheet 20 can be easily removed from the storage frame 11 only by releasing the grip of the lower grip 60.

  A method for storing the seat 20 will be described. As shown in FIG. 3, the storage of the sheet 20 functions as a horizontal member by folding the upper side of the sheet 20 while maintaining the state where the lower end portion of the sheet 20 is gripped by the lower grip portion 60. It is placed on the lower metal pressing portion 66 to be pressed.

  The middle pillar 14 in a state of being laid down on the sheet 20 is placed, and the protection pillar 90 covers the middle pillar 14 and the sheet 20 from above. Next, the checker plate 5 is set on the upper part of the storage frame 11 as a lid member. When the checker plate 5 is attached to the storage frame 11, the checker plate 5 is substantially flush with the ground FL. The checker plate 6 for the support frame 15 is also placed on the support frame 15 from which the center pillar 14 has been pulled out.

  When the waterproof device 10 is used, the procedure is the reverse of that for storing. As shown in FIG. 1, the lower end of the sheet 20 during use is gripped by the lower grip 60, and both left and right sides thereof are gripped by the side grips 40 of the vertical frame 12. The pressing direction of the lower metal part pressing part 66 and the side metal part pressing part 42 is the same as the assumed water intrusion direction. Then, the sheet 20 is supported in a state where its longitudinal direction is oriented in a direction orthogonal to the direction of water entry in plan view. In the present embodiment, the holding state of the sheet 20 is made more stable by the wire 25 and the middle pillar 14.

According to the waterproof device 10 of the embodiment described above, the following effects can be obtained.
The waterproof device 10 is buried in the ground FL and has a storage frame 11 to which the lower side of the stretched sheet 20 is fixed, and a space between the storage frame 11 and the bottom 110 of the storage frame 11.
