FIG.

[Waterproof board device]
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, a waterproof board device 1 to which a waterproof board pressing device 10 according to an embodiment of the present invention is attached will be described. In Fig. 1 and Fig. 2, reference numeral 1 denotes a waterproof board device, which includes guide rails 2L and 2R (an example of a column body) and waterproof boards 3A, 3B, and 3C.

In the following explanation, the width direction (longitudinal direction) of the waterproof boards 3A, 3B, 3C may be referred to as the left-right direction, the thickness direction of the waterproof boards 3A, 3B, 3C as the front-rear direction, and the height direction of the waterproof boards 3A, 3B, 3C as the up-down direction. In addition, in the front-rear direction, the side of the waterproof boards 3A, 3B, 3C that receives water pressure may be referred to as the outdoor side (front side), and the side that prevents water from entering may be referred to as the indoor side (rear side).

The guide rails 2L, 2R are extruded shapes made of metal such as aluminum, and are erected on both the left and right sides of the entrance 4. For example, as shown in Figures 1 and 2, the guide rails 2L, 2R in this embodiment are attached to the front of the side walls 5L, 5R located on both the left and right sides of the entrance 4, but they may also be attached to the inner surfaces of the side walls 5L, 5R (see Figure 7) or embedded in the side walls 5L, 5R.

After construction, the guide rails 2L, 2R are left integrated with the side walls 5L, 5R. The guide rails 2L, 2R can be made detachable from the side walls 5L, 5R, and can be stored in a warehouse or the like when removed, and installed along the side walls 5L, 5R only when in use.

The waterproof boards 3A, 3B, and 3C of this embodiment are made of metal panel material with a certain rigidity, and are composed of three sheets that can be stacked in series in the vertical direction, and can be fitted together or separated from each other. Such split waterproof boards 3A, 3B, and 3C not only allow for compact storage in a warehouse when removed, but also make it easy to transport them when in use and when removed.

The widthwise ends of the waterproof boards 3A, 3B, and 3C are inserted into the insertion grooves 2a formed in the guide rails 2L and 2R, and are held upright to block the entrance 4. Specifically, when the widthwise ends of the waterproof boards 3A, 3B, and 3C are inserted from above into the insertion grooves 2a of the guide rails 2L and 2R, starting from the lower waterproof boards 3A, 3B, and 3C, the waterproof boards 3A, 3B, and 3C are guided by the guide rails 2L and 2R to move downward, and are stacked in order to form a waterproof wall W at the entrance 4.

At least the lower end surface of the waterproof board 3A located at the lowest level is provided with a water-stopping material 3a that abuts against the floor surface 4a of the entrance/exit 4. The water-stopping material 3a is made of a rubber-like elastic material, and by elastically abutting against the floor surface 4a of the entrance/exit 4, it suppresses water leakage between the lower end surface of the waterproof board 3A and the floor surface 4a. However, when the waterproof boards 3A, 3B, and 3C are subjected to water pressure, the waterproof board 3A at the lowest level may lift off the floor surface 4a, or gaps may occur between the waterproof boards 3A, 3B, and 3C, increasing the amount of water leakage. The waterproof board pressing device 10 according to the embodiment of the present invention is attached to a new or existing waterproof board device 1 to suppress the above-mentioned water leakage.

The waterproof board pressing device 10 according to the embodiment of the present invention can also be attached to a waterproof board device 1B of a double-mounted type as shown in FIG. 8. The waterproof board device 1B of a double-mounted type is applied to an entrance 4B with a wide opening width, and includes a pair of left and right guide rails 2L, 2R, a center post 6 (another example of a pillar body) having insertion grooves on both the left and right sides and removably installed between the left and right guide rails 2L, 2R, a first set of waterproof boards 3A, 3B, 3C that are held upright between the left guide rail 2L and the center post 6, and a second set of waterproof boards 3A, 3B, 3C that are held upright between the right guide rail 2R and the center post 6. The waterproof board pressing device 10 according to the embodiment of the present invention will be described below.

[Waterproof board pressing device]
As shown in Figures 1 to 8, the waterproof board pressing device 10 comprises an installation section 11 that is mounted in a bridging manner between a pair of guide rails 2L, 2R (see Figures 1 and 2) that hold waterproof boards 3A, 3B, 3C, and a pressing section 12 that is provided at least in the widthwise middle portion of the installation section 11 and presses the widthwise middle portions of the waterproof boards 3A, 3B, 3C downward.

The installation section 11 may be installed in a bridging manner between a pair of side walls 5L, 5R to which the guide rails 2L, 2R are attached as shown in FIG. 7, or may be installed in a bridging manner between the guide rails 2L, 2R and the center column 6 as shown in FIG. 8. The waterproof board pressing device 10 shown in FIGS. 1 to 8 includes three pressing sections 12 that press downward the widthwise middle section and both widthwise ends of the waterproof boards 3A, 3B, 3C, but the number and positions of the pressing sections 12 can be changed as appropriate.

This type of waterproof board pressing device 10 can press the widthwise middle parts of the waterproof boards 3A, 3B, and 3C downward, eliminating the shortage of pressing force in the widthwise middle parts of the waterproof boards 3A, 3B, and 3C and improving waterproof performance.

Specifically, the installation section 11 is a rectangular cylindrical extrusion made of aluminum or other metal, and at both left and right ends, mounting sections 13A and 13B are provided that can be detachably attached to the guide rails 2L and 2R, the center column 6, or the side walls 5L and 5R.

In this embodiment, the mounting parts 13A and 13B elastically abut against the guide rails 2L and 2R, the center post 6, or the side walls 5L and 5R from the inside, and are mounted in a tensioned state between a pair of guide rails 2L and 2R, between the guide rails 2L and 2R and the center post 6, or between a pair of side walls 5L and 5R.

One of the mounting parts 13A has a fixed pressing rod 15 that protrudes outward from one of the left and right ends of the installation part 11, and a rubber elastic member 15a is provided at its tip.

The other mounting part 13B has a movable pressing rod 16 that protrudes outward from the other left-right end of the installation part 11, and a rubber elastic member 16a is provided at the tip of the rod. The movable pressing rod 16 is screwed to the other left-right end of the installation part 11 so that it can move back and forth in the left-right direction, and the amount of protrusion from the installation part 11 can be adjusted based on the rotation of a lever handle 16b provided in the middle part.

With such mounting parts 13A and 13B, after disposing the waterproof board pressing device 10 between a pair of guide rails 2L and 2R, between the guide rails 2L and 2R and the center post 6, or between a pair of side walls 5L and 5R, by turning the lever handle 16b to change the position of the movable pressing rod 16 in the protruding direction, the rubber elastic members 15a and 15b of both mounting parts 13A and 13B elastically abut against the guide rails 2L and 2R, the center post 6, or the side walls 5L and 5R from the inside. This makes it possible to mount the waterproof board pressing device 10 in a tensioned state between a pair of guide rails 2L and 2R, between the guide rails 2L and 2R and the center post 6, or between a pair of side walls 5L and 5R.

This mounting structure for the waterproof board pressing device 10 eliminates the need to provide mounting members or perform mounting processing on the guide rails 2L, 2R, center column 6, or side walls 5L, 5R, so it is possible to provide a waterproof board pressing device 10 that can be easily mounted not only when a new waterproof board device 1 is installed, but also on an existing waterproof board device 1.

The pressing portion 12 includes a bolt portion 17 that is screwed into the erection portion 11 so as to be movable up and down, a rotating handle 18 (rotating operation portion) that is provided at the upper end of the bolt portion 17 and rotates and operates the bolt portion 17, and an abutment portion 19 that is provided at the lower end of the bolt portion 17 and can abut against the upper end of the waterproof board 3C. The abutment portion 19 has a U-shape that opens downward and fits into the upper end of the waterproof board 3C. In other words, the abutment portion 19 includes a first surface portion 19a that is connected to the lower end of the bolt portion 17 and that runs along the upper end surface of the waterproof board 3C, and a second surface portion 19b and a third surface portion 19c that extend downward from both the front and rear ends of the first surface portion 19a and run along the front and rear surfaces of the waterproof board 3C. As shown in FIG. 6, the lower end of the bolt 17 penetrates the first surface 19a of the abutment 19 and supports the abutment 19 in a manner that prevents it from coming loose via a pair of retaining members 17a, 17b. As a result, the abutment 19 is connected to the lower end of the bolt 17 so as to be rotatable relative to the lower end of the bolt 17, so that it does not rotate together with the bolt 17 when the rotary handle 18 is rotated. In addition, a rubber-based elastic member such as a rubber sheet is attached to the inner surface of the abutment 19 (the surface that abuts against the waterproof board 3C).

According to this pressing part 12, the waterproof boards 3A, 3B, and 3C are pressed downward by turning the bolt part 17, so the configuration of the pressing part 12 is simple and the pressing force of the waterproof boards 3A, 3B, and 3C can be easily adjusted. In addition, the abutment part 19 of the pressing part 12 has a U-shape that opens downward and fits into the upper end of the waterproof board 3C, so not only can the waterproof boards 3A, 3B, and 3C be pressed downward, but also the displacement of the waterproof boards 3A, 3B, and 3C in the thickness direction can be suppressed. In addition, when the waterproof board pressing device 10 is attached to the waterproof board device 1, if the abutment part 19 of the pressing part 12 is fitted into the upper end of the waterproof board 3C, not only can the waterproof board pressing device 10 be temporarily held, but the waterproof board pressing device 10 can be positioned relative to the waterproof boards 3A, 3B, and 3C, making the installation work of the waterproof board pressing device 10 easier.

According to the present embodiment configured as described above, the waterproof board pressing device 10 is attached to the waterproof board device 1. The waterproof board device 1 includes waterproof boards 3A, 3B, 3C that block water intrusion, and at least a pair of guide rails 2L, 2R that hold both ends of the waterproof boards 3A, 3B, 3C in the width direction. The waterproof board pressing device 10 includes an installation part 11 that is installed in a bridging manner between the pair of guide rails 2L, 2R that hold the waterproof boards 3A, 3B, 3C, between the guide rails 2L, 2R and the center column 6, or between the pair of side walls 5L, 5R to which the pair of guide rails 2L, 2R are attached, and a pressing part 12 that is provided at least in the middle of the width direction of the installation part 11 and presses the middle part of the width direction of the waterproof boards 3A, 3B, 3C downward, thereby eliminating the shortage of pressing force in the middle part of the width direction of the waterproof boards 3A, 3B, 3C and improving the waterproof performance.

In addition, mounting parts 13A, 13B are provided at both widthwise ends of the erection section 11, which are detachably attached to the guide rails 2L, 2R, center pillar 6, or side walls 5L, 5R. The mounting parts 13A, 13B are attached to the guide rails 2L, 2R, center pillar 6, or side walls 5L, 5R by elastically abutting against the guide rails 2L, 2R, center pillar 6, or side walls 5L, 5R. This means that there is no need to provide mounting members or perform mounting processing on the guide rails 2L, 2R, center pillar 6, or side walls 5L, 5R. As a result, it is possible to provide a waterproof board pressing device 10 that can be easily attached not only when a waterproof board device 1 is newly installed, but also to an existing waterproof board device 1.

In addition, the pressing part 12 includes a bolt part 17 that is screwed into the erection part 11 so as to be movable up and down, a rotating handle 18 that is provided at the upper end of the bolt part 17 and that rotates the bolt part 17, and an abutment part 19 that is provided at the lower end of the bolt part 17 and that can abut against the upper end of the waterproof board 3C. This not only simplifies the configuration of the pressing part 12, but also makes it easy to adjust the pressing force of the waterproof boards 3A, 3B, and 3C.

In addition, the abutment portion 19 has a U-shape that opens downward and fits onto the upper end of the waterproof board 3C, so that not only can the waterproof boards 3A, 3B, and 3C be pressed downward, but also the displacement of the waterproof boards 3A, 3B, and 3C in the thickness direction can be suppressed. In addition, when attaching the waterproof board pressing device 10 to the waterproof board device 1, by fitting the abutment portion 19 onto the upper end of the waterproof board 3C, not only can the waterproof board pressing device 10 be temporarily held, but the waterproof board pressing device 10 can also be positioned relative to the waterproof boards 3A, 3B, and 3C, making it easier to attach the waterproof board pressing device 10.

[Other embodiments]
Next, a second and third embodiment of the present invention will be described with reference to Fig. 9 to Fig. 12. However, the same reference numerals as in the first embodiment are used for configurations common to the first and third embodiments, and the description of the first embodiment may be used.

9, 10 and 11(a), the waterproof board pressing device 10B of the second embodiment differs from the first embodiment in the structure of the mounting part 13C provided at both left and right ends of the erection part 11, and the mounting part 13C of the second embodiment is attached to the guide rails 2L and 2R by being clamped between the guide rails 2L and 2R. Specifically, the mounting part 13C of the second embodiment is screwed to both left and right ends of the erection part 11 so as to be movable in the left and right directions, and includes a first movable pressing rod 20 that protrudes outward from both left and right ends of the erection part 11, and a second movable pressing rod 22 that is arranged coaxially with the first movable pressing rod 20 and connected via a connecting member 21.

The connecting member 21 is a U-shaped member when viewed from the front that opens downward, and the width of the opening is greater than the thickness of the upper edge 2b (e.g., the upper edge of the outer end wall) of the guide rails 2L and 2R. In other words, the connecting member 21 is configured to be loosely fitted from above into the upper edge 2b of the guide rails 2L and 2R.

Of the opposing surface portions 21a and 21b of the connecting member 21, the outer end portion of the first movable pressing bar 20 is connected in a penetrating state to one opposing surface portion 21a, and the inner end portion of the second movable pressing bar 22 is screwed to the other opposing surface portion 21b so that it can move back and forth in the left and right direction. Rubber elastic members 20a and 22a are provided on the outer end surface of the first movable pressing bar 20 and the inner end surface of the second movable pressing bar 22, respectively. A lever handle 22b is provided at the middle portion of the second movable pressing bar 22 in the left and right direction, and the second movable pressing bar 22 can be moved back and forth in the left and right direction by turning the lever handle 22b.

When mounting the waterproof board pressing device 10B of the second embodiment to the waterproof board device 1, the protruding position of the first movable pressing rod 20 of the left and right mounting parts 13C is adjusted so that the rubber elastic member 20a provided on the first movable pressing rod 20 abuts or is close to the inner surface of the upper edge portion 2b of the guide rails 2L, 2R when mounted. It is desirable to perform this adjustment in advance.

Next, the connecting members 21 of the left and right mounting parts 13C are loosely fitted from above onto the upper edge parts 2b of the guide rails 2L and 2R, and then the second movable pressing bar 22 is moved toward the first pressing bar 20 by turning the lever handle 22b, so that the upper edge parts 2b of the guide rails 2L and 2R are sandwiched between the two movable pressing bars 20 and 22 via the rubber elastic members 20a and 22a.

This type of mounting part 13C allows the waterproof board pressing device 10B to be firmly mounted to the left and right guide rails 2L, 2R, but there is a risk that the clamping type mounting part 13C cannot be mounted to the center post 6.

As shown in FIG. 11(b), the waterproof board pressing device 10C of the third embodiment differs from the previous embodiment in that it has the mounting part 13B of the first embodiment at one left-right end of the erection part 11 and the mounting part 13C of the second embodiment at the other left-right end of the erection part 11.

According to the third embodiment of the waterproof board pressing device 10C, as shown in FIG. 12, by attaching one mounting part 13B to the center post 6 and the other mounting part 13C to the guide rails 2L and 2R, it becomes possible to apply the clamping type mounting part 13C to the waterproof board device 1B with a connected specification.

Of course, the present invention is not limited to the above embodiment. For example, in the above embodiment, the waterproof wall W is composed of three laminated waterproof boards 3A, 3B, and 3C, but the waterproof wall W may be composed of one or two waterproof boards, or may be composed of four or more waterproof boards. Also, the guide rails 2L and 2R in the above embodiment are extruded shapes, but guide rails composed of bent sheet metal can also be used without any problems.
