Then, while pressing the water stop plate against the lower floor surface, the male screw of the bolt is screwed onto the nut portion of the support receiving hook portion that has locked the locking portion to the frame, and the tightening portion is tightened. Accordingly, the water stop plate is pressed and fixed to the frame and the floor surface, and the front packings at both ends provided between the water stop plate and the frame are compressed by the pressing force of the water stop plate pressing tool. At this time, the bottom packing of the water stop plate is compressed by receiving a downward pressing force mainly by the weight of the water stop plate. Further, in Patent Document 1, by configuring the water stop plate pressing tool so as to face obliquely downward, the pressing force of the water stop plate pressing tool is applied not only to the front surface packing of both ends but also to the lower surface packing. It is disclosed to add.

  The waterproof device described in Patent Literature 2 includes a plurality of support columns that are detachably attached to a hole provided on a flat foundation, and a plurality of wall surface panels that are supported between the support columns. The wall surface panel is formed by integrally fixing a water stop material having elasticity along both sides and a lower side thereof. When installing this waterproof device, insert the pillars into the holes and place them in a row on the foundation, and fit the side edge of the wall panel into the recessed groove provided on the side of the pillar, Install the wall panel. As a result, a water blocking wall is formed on the foundation. In the installed state, the water stop material on the lower side of the wall panel is compressed by receiving a downward pressing force by the weight of the wall panel. Also, if the wall panel is set to a small vertical width so that it is easy to transport and install the wall panel, and the multi-stage wall panel is placed between the columns, the bottom edge of the wall panel is stopped. The water material is compressed by receiving a downward pressing force by the weight of the wall surface panel disposed in the upper stage in addition to the weight of the wall surface panel.

  The waterproof device described in Patent Literature 3 includes a guide, a waterproof plate, a lowermost waterproof plate, and a pressing unit. The guide guides and holds the left and right ends of the waterproof board and the lowermost waterproof board, respectively. As for the waterproof board, a connection part water stop material is arrange | positioned at the upper end part, and the guide water stop material is arrange | positioned at the edge part inserted in a guide among the surfaces used as an inner side. As with the waterproof board, the lowermost waterproof board has a connecting part water stop material and a guide water stop material, and a lower end water stop material at the lower end. The lower end water stop material includes a first water stop material and a second water stop material having a surface that is partly fixed to the lower surface of the first water stop material and receives water pressure from the water retained on the outside. The pressing means is a wedge-shaped member and presses the waterproof board and the lowermost waterproof body inward and outward.

  Further, this waterproof device is provided with a piece below the lowermost waterproof plate and above the bottom water stop material. This piece is formed so as to protrude perpendicularly to the surface of the lowermost waterproof board. When the waterproof plate is stored in a normal state, the waterproof plate and the lowermost waterproof plate can be combined into one by placing the waterproof plate on the upper surface of the piece. Therefore, this piece is configured to have a strength sufficient to support the weight of the waterproof plate, and is not configured to apply a downward pressing force to the lower end water stop material.

  When installing this waterproof device, the end of the lowermost waterproof plate is inserted into a groove formed in the guide, and the lowermost waterproof plate is disposed between the guides. Similarly, a waterproof board is arrange | positioned on a lowermost waterproof board. Then, a pressing member is inserted between the waterproof board on the side where the guide water-stopping material is not arranged and the guide, and between the lowermost waterproof board on the side where no guide water-stopping material is arranged and the guide. Thereby, the waterproof board and the lowermost waterproof board are pushed to the side opposite to the pressing means, and the guide water-stopping material comes into strong contact with the guide to ensure water-stopping. In this state, the bottom water stop material of the lowermost waterproof plate is compressed by receiving a downward pressing force due to the weight of the lowermost waterproof plate and the weight of the waterproof plate. Further, when water stays outside, the second water stop material is pressed downward by the water pressure of the water.

Japanese Patent No. 4810059 Japanese Patent No. 5514943 JP 2014-163081 A

  As described above, in the waterproof device described in Patent Document 1 to Patent Document 3, the downward pressing force applied to the water stop material (packing) provided at the lower end of the waterproof plate (water stop plate, wall panel). Is mainly caused by the weight of the waterproof plate. However, the waterproof device described above is required to reduce the weight of the waterproof plate as much as possible in order to facilitate the installation work. If the waterproof board is reduced in weight in response to this demand, the pressing force against the water stop material at the lower end of the waterproof board is reduced, so that the water stoppage between the waterproof board and the road surface may be reduced.

  In the waterproof device described in Patent Document 1, a part of the pressing force by the water stop plate pressing tool presses the lower surface packing downward by installing the water stop plate pressing tool obliquely downward. In order to mainly press the front packings at both ends, it cannot be said that the weight reduction of the water stop plate is considered. Further, in the waterproof device described in Patent Document 3, the second water stop material of the lower end water stop material is pressed downward by the water pressure of the accumulated water so as to increase the water stop performance between the waterproof plate and the road surface. However, when the water pressure is small, the effect is small and it cannot be said that it is sufficient.

  The present invention increases the water stoppage between the waterproof member and the installation surface by applying a sufficient pressing force to the elastic member provided at the lower end of the waterproof member regardless of the size of the waterproof member's own weight. An object of the present invention is to provide a waterproof device capable of performing the above.

According to one aspect of the present invention, a waterproof device includes a waterproof member supported by a support provided on an installation surface, and an elastic member provided at a lower end portion of the waterproof member and elastically deformable in the vertical direction. And a pressing portion provided on the waterproof member and capable of applying the vertical force to the elastic member. The pressing portion has a pressing surface that intersects the vertical direction and opens upward.
According to said waterproof device, the press part which can apply the force of an up-down direction to an elastic member is provided, This press part cross | intersects an up-down direction, and has a press surface open | released upwards. For this reason, when the waterproof member is installed, the operator can easily apply a downward pressing force in the vertical direction to the elastic member by pressing the pressing surface. Therefore, even if the weight of the waterproofing member is light and sufficient weight cannot be applied to the elastic member by its own weight, sufficient pressure can be applied to the elastic member. Thereby, the water stop property between a waterproofing member and an installation surface can be improved.

In the waterproof device, the pressing portion may be provided at a position below the upper end portion of the waterproof member and above the elastic member.
According to the waterproof device, the pressing portion is provided at a position below the upper end portion of the waterproof member and above the elastic member. That is, since the pressing portion is provided within a range where the operator can work with his / her hands and feet, the operator can easily press the pressing surface of the pressing portion with his / her hands and feet. Therefore, the efficiency of the installation work of the waterproof member can be improved.

In the waterproof device, the pressing portion may be disposed at a position protruding from the elastic member in a direction intersecting the vertical direction when viewed from the vertical direction.
According to the waterproof device, the pressing portion is arranged at a position protruding from the elastic member in a direction intersecting the vertical direction when viewed from the vertical direction. For this reason, at the time of installation work of a waterproof member, even if the waterproof member is in an inclined state, an operator can easily put his hand or foot on the pressing portion. Therefore, the installation work of the waterproof member can be performed more efficiently.

In the above waterproof device, the pressing portion may be formed of a saddle member attached to the waterproof member.
According to the above waterproof device, since the pressing portion is constituted by the saddle member attached to the waterproof member, the dimensions of the saddle member which is a separate member from the waterproof member regardless of the dimension in the thickness direction of the waterproof member, etc. By appropriately adjusting, a sufficient width of the pressing surface can be ensured. In addition, regardless of the rigidity of the waterproof member, it is possible to ensure sufficient strength against the pressing force applied to the pressing surface by appropriately adjusting the rigidity of the saddle member. Therefore, even if the dimension of the waterproof member itself in the thickness direction is small, the pressing portion can have a sufficiently large pressing surface and high strength.

The waterproof device may further include a reinforcing member that has higher rigidity than the elastic member and is disposed along the elastic member in the vertical direction. The lower end of the reinforcing member may be positioned below an intermediate position in the vertical direction of the elastic member in a state where the elastic member is not elastically deformed.
According to the waterproof device, since the reinforcing member having higher rigidity than the elastic member and disposed in the vertical direction along the elastic member is provided, the elastic member causes excessive elastic deformation of the elastic member. And buckling by this elastic deformation can be prevented. Further, the lower end of the reinforcing member is positioned below the intermediate position in the vertical direction of the elastic member in a state where the elastic member is not elastically deformed. Can be reliably reinforced. Therefore, the waterproof property between the waterproof member by the elastic member and the installation surface can be maintained for a long time.

In the waterproof device, the reinforcing member may be provided apart from the elastic member in a direction intersecting the up-down direction.
According to the waterproof device, since the reinforcing member is spaced apart from the elastic member in the direction intersecting the vertical direction, a gap is formed between the reinforcing member and the elastic member. When this gap is not present, the elastic member is restrained by the reinforcing member along the vertical direction from the beginning of the elastic deformation, so that the lateral deformation caused by the vertical elastic deformation is suppressed, and the vertical direction The elastic deformation itself becomes difficult. Therefore, by providing a gap between the reinforcing member and the elastic member, the elastic member can be appropriately elastically deformed in the vertical direction. At the same time, significant deformation due to buckling or the like of the elastic member can be suppressed by a reinforcing member provided apart from the elastic member.

In the waterproof device, the reinforcing member may include an extending portion that extends from the lower end of the reinforcing member toward the elastic member.
According to the waterproof device, since the reinforcing member has the extending portion extending from the lower end of the reinforcing member toward the elastic member, the deformation of the elastic member adjacent to the extending portion is intensively suppressed. be able to.

In the waterproof device, the waterproof member may include an engaging portion provided above the lower end portion of the waterproof member. The state in which the elastic member is elastically deformed in the vertical direction may be maintained by engaging the engaging portion with an engaged portion provided on the support.
According to the waterproof device, the waterproof member has an engaging portion provided above the lower end portion of the waterproof member, and the engaging portion engages with an engaged portion provided on the support. Thus, the state in which the elastic member is elastically deformed in the vertical direction is maintained. Therefore, due to the engagement between the engaging portion and the engaged portion, it is possible to maintain the state of the elastic member that is elastically deformed in the vertical direction by applying a sufficient pressing force by the pressing portion. Accordingly, it is possible to maintain a state in which the water stoppage between the waterproof member and the installation surface is increased.

  According to said waterproof device, the press part which can apply the force of an up-down direction to an elastic member is provided, This press part cross | intersects an up-down direction, and has a press surface open | released upwards. For this reason, when the waterproof member is installed, the operator can easily apply a downward pressing force in the vertical direction to the elastic member by pressing the pressing surface. Therefore, even if the weight of the waterproofing member is light and sufficient weight cannot be applied to the elastic member by its own weight, sufficient pressure can be applied to the elastic member. Thereby, the water stop property between a waterproofing member and an installation surface can be improved.

The dimensions of the auxiliary members 12a, 12c, and 12d in the thickness direction At1 are set so as to fit within the flange portions 11a, 11c, and 11d, respectively. The dimension of the auxiliary member 12b in the thickness direction At1 is larger than the dimension of the flange part 11b in the thickness direction At1, and the auxiliary member 12b protrudes from the flange part 11b to the back side. The auxiliary member 12b functions as the pressing part 40. In addition, the structure of the waterproof member 10 mentioned above is an example, Comprising: It is not limited to this.

  As a material of the waterproof member 10, for example, aluminum can be used. Further, as the material of the auxiliary members 12a, 12b, 12c, and 12d, for example, aluminum can be used similarly to the waterproof member 10.

  The elastic member 20 is provided at the lower end portion 10 b of the waterproof member 10. In the present embodiment, the elastic member 20 is provided over the entire width direction Aw <b> 1 of the waterproof member 10 below the flange portion 11 b formed at the lower end portion 10 b of the waterproof member 10. The elastic member 20 is provided to seal a gap between the installation surface 90 such as a passage surface of the entrance / exit 91 and the waterproof member 10 and prevent water from entering the gap. The elastic member 20 is elastically deformable at least in the vertical direction Av1.

  In this embodiment, as FIG. 5 shows, the elastic member 20 is comprised from the upper elastic member 20a and the lower elastic member 20b provided in the lower side of the upper elastic member 20a. For example, chloroprene rubber (CR) can be used as the material of the upper elastic member 20a, and ethylene / propylene / diene rubber (EPDM) can be used as the material of the lower elastic member 20b. In addition, the structure of the elastic member 20 mentioned above is an example, and the elastic member 20 may be comprised only by the single elastic member, and may be comprised from the some elastic member.

  In the present embodiment, the elastic member 25 is provided on the front surface 10 e of the waterproof member 10, that is, the surface of the waterproof member 10 that faces the support body 50. The elastic member 25 is provided to seal the gap between the support 50 and the waterproof member 10 and prevent water from entering from the gap. The elastic member 25 is elastically deformable at least in the thickness direction At1. The elastic member 25 should just be provided in the range which contact | abuts at least to the support body 50 among the front surfaces 10e of the waterproof member 10, and the area | region which contact | abuts at least the support body 50 among the surfaces of the front surface side of the elastic member 20. In the present embodiment, the front surface 10e in the right side portion 10R and the left side portion 10L which are the side portions of the waterproof member 10 in the width direction Aw1 includes a range where the above-described support 50 is in contact. Therefore, as shown in FIG. 3, the elastic member 25 is formed on the front surface 10e of the right side portion 10R and the left side portion 10L, and on the front side surface of the portion of the elastic member 20 disposed on the right side portion 10R and the left side portion 10L. Is provided. Further, the dimension in the vertical direction Av1 of the elastic member 25 in a state where it is not elastically deformed is the same as the dimension in the vertical direction Av1 of the waterproof member 10 in a state where the elastic member 20 is installed. The dimension in the thickness direction At1 of the elastic member 25 in a state where the elastic member 25 is not elastically deformed is such that the inclined member 61 of the holding member 60 described later is in contact with the inclined surface 31a of the engaging member 30 and the waterproof member 10 and the support body 50. Greater than the distance between. Therefore, in a state where the inclined portion 61 is in contact with the inclined surface 31a, the elastic member 25 is elastically deformed so as to contract in the thickness direction At1. As a material of the elastic member 25, for example, chloroprene rubber (CR) can be used.

  The pressing portion 40 is provided in the waterproof member 10 and can apply a force in the vertical direction Av <b> 1 to the elastic member 20. In this embodiment, the pressing part 40 is comprised from the auxiliary member (saddle material) 12b attached to the waterproof member 10. FIG. That is, the auxiliary member 12 b functions as the pressing portion 40. As shown in FIGS. 1, 4, and 5, the pressing portion 40 has a pressing surface 40 a that intersects the vertical direction Av <b> 1 and is opened upward. That is, in this embodiment, the upper surface of the auxiliary member 12b functions as the pressing surface 40a. The pressing unit 40 applies a pressing force that elastically deforms the elastic member 20 so as to contract in the vertical direction Av1 when the engaging member 30 is engaged with the holding member 60 and the waterproof member 10 is supported by the support body 50. It is provided for. For example, the operator applies a downward pressing force to the elastic member 20 by pressing the pressing surface 40a by hand or stepping on the foot with the foot. For this reason, it is preferable that the pressing portion 40 is provided at a position below the upper end portion 10 a of the waterproof member 10 and above the elastic member 20. In addition, even when the waterproof member 10 is in an inclined state, the pressing portion 40 moves from the elastic member 20 to the vertical direction when viewed from the vertical direction Av1 so that the operator can easily put his hand or foot on the pressing portion 40. It is preferable to be disposed at a position protruding in a direction intersecting Av1 (for example, thickness direction At1).

  As described above, the pressing surface 40a is opened upward. Here, the pressing surface is “opened upward” means that the pressing surface is at least the pressing surface so that the operator can apply force to the pressing surface using pressing means such as his / her hand or foot. It means having a space enough to arrange the pressing means above. For example, assuming that the operator presses the pressing surface 40a with his / her hand, the pressing surface 40a is at least above the pressing surface 40a, and the operator can put a hand on the pressing surface 40a and apply a downward pressing force in the vertical direction Av1. It is sufficient to have only a space. If it is assumed that the operator presses the pressing surface 40a with his / her foot, the pressing surface 40a can be applied with a downward pressing force on the pressing surface 40a at least above the pressing surface 40a by the operator placing his / her foot on the pressing surface 40a. It is sufficient to have only a space.

  In this embodiment, since the pressing part 40 is comprised from the auxiliary member 12b attached to the waterproof member 10, the auxiliary | assistant which is a different member from the waterproof member 10 irrespective of the dimension of the thickness direction At1 of the waterproof member 10, etc. By appropriately adjusting the dimension of the member 12b, a sufficient width of the pressing surface 40a can be ensured. Regardless of the rigidity of the waterproof member 10, by appropriately adjusting the rigidity of the auxiliary member 12b, it is possible to ensure sufficient strength against the pressing force applied to the pressing surface 40a. Due to the configuration described above, the pressing member 40 has sufficient rigidity even when the auxiliary member 12b is supported in a cantilevered state with respect to the waterproof member 10 as in the present embodiment. In the present embodiment, the auxiliary member 12b is formed in a hollow tubular shape. For this reason, a connecting bolt or the like for connecting to the waterproof member 10 can be inserted into the auxiliary member 12b.

  Moreover, in this embodiment, although the press part 40 is provided over the whole width direction Aw1 of the waterproof member 10, it is not restricted to this structure. For example, the pressing portion 40 may be provided only in a part of the waterproof member 10 in the width direction Aw1. Moreover, although the press part 40 is provided so that it may protrude in thickness direction At1, it does not need to protrude. For example, the dimension in the thickness direction At1 of the auxiliary member 12b constituting the pressing portion 40 may be the same as or smaller than the dimension in the thickness direction At1 of the auxiliary members 12a, 12c, and 12d. Moreover, it is good also considering the flange part 11b as the press part 40 which makes the upper surface the press surface 40a, without providing the auxiliary member 12b in the waterproof member 10. FIG.

  The waterproof device 1 may further include a reinforcing member 35 that has higher rigidity than the elastic member 20 and is disposed along the elastic member 20 in the vertical direction Av1. The reinforcing member 35 is provided to prevent excessive elastic deformation of the elastic member 20 and buckling due to this elastic deformation. As shown in FIG. 5, in this embodiment, the reinforcing member 35 is formed integrally with the flange portion 11b of the waterproof member 10, and extends along the elastic member 20 downward from the tip 11ba of the flange portion 11b in the vertical direction Av1. ing. Therefore, for example, aluminum can be used as the material of the reinforcing member 35 in the same manner as the waterproof member 10. Note that the reinforcing member 35 is not necessarily formed integrally with the flange portion 11b. Further, the lower end 35b of the reinforcing member 35 is positioned below the intermediate position in the vertical direction Av1 of the elastic member 20 in a state where the elastic member 20 is not elastically deformed. Thereby, the vicinity of the intermediate position in the up-down direction Av1 of the elastic member 20 in which buckling or the like is likely to occur can be reliably reinforced.

  When there is no gap between the reinforcing member 35 and the elastic member 20 and the reinforcing member 35 is in contact with the elastic member 20, the elastic member 20 moves from the beginning of elastic deformation to the reinforcing member 35 along the vertical direction Av <b> 1. You will be bound. For this reason, the deformation to the side (thickness direction At1) caused by the elastic deformation of the elastic member 20 in the vertical direction Av1 is suppressed, and as a result, the elastic deformation in the vertical direction Av1 itself is difficult to be performed. For this reason, it is preferable that the reinforcing member 35 is provided away from the elastic member 20 in a direction (for example, the thickness direction At1) intersecting the up-down direction Av1. By providing a gap between the reinforcing member 35 and the elastic member 20, the elastic member 20 can appropriately perform the elastic deformation in the vertical direction Av <b> 1 and the accompanying elastic deformation in the lateral direction. At the same time, significant deformation due to buckling or the like in the elastic member 20 can be suppressed by restraining the elastic member 20 with the reinforcing member 35 provided away from the elastic member 20.

  Further, the waterproof member 10 includes an engagement member (engagement portion) 30 provided above the lower end portion 10 b of the waterproof member 10, and the engagement member 30 is provided on a support member 50 (covered member). The state in which the elastic member 20 is elastically deformed in the vertical direction Av <b> 1 may be maintained by engaging with the (engagement portion) 60.

  FIG. 6 is an enlarged view showing the engaging member 30 of the waterproof member 10. In the present embodiment, as shown in FIG. 6, the engaging member 30 is provided on the upper end portion 10 a of the waterproof member 10. Further, since the engaging member 30 engages with the holding member 60 provided on the support body 50, a portion of the waterproof member 10 that contacts the support body 50, that is, the right side portion 10 </ b> R of the waterproof member 10 that faces the support body 50. And the left side portion 10L. The engaging member 30 is composed of a plate-like member, and has an inclined portion 31 formed by bending one end side of the plate-like member. The inclined portion 31 has an inclined surface 31 a that faces upward and is inclined upward from the engaging member 30. The engaging member 30 is provided on the waterproof member 10 so that the inclined portion 31 is disposed on the front side of the waterproof member 10 facing the support body 50. Therefore, the inclined surface 31a is provided on the waterproof member 10 so as to face upward, and is inclined so as to go upward as it goes from the waterproof member 10 to the support body 50. Further, the inclined surface 31 a of the engaging member 30 is positioned above the inclined portion 61 of the holding member 60 provided on the support body 50 in a state where the elastic member 20 is not elastically deformed. Therefore, in a state where the engaging member 30 is engaged with the holding member 60, a force for compressing the elastic member 20 in the vertical direction Av1 is always applied. That is, the state in which the elastic member 20 is elastically deformed in the vertical direction Av1 is maintained.

  In the present embodiment, the inclined portion 31 of the engaging member 30 is disposed so as to protrude in the thickness direction At1 with respect to the front surface 10e of the waterproof member 10. Since the elastic member 25 is provided on the lower side of the inclined portion 31, when the waterproof member 10 is supported by the support body 50, the inclined portion 31 comes into contact with the support body 50 so that the elastic member 25 is appropriately placed in the thickness direction At1. In order to prevent the incompressible compression, the dimension in the thickness direction At1 of the inclined portion 31 is smaller than the dimension in the thickness direction At1 of the elastic member 25 that is not elastically deformed. Further, as the material of the engaging member 30, for example, stainless steel can be used. The engaging member 30 is attached to the waterproof member 10 using, for example, rivets.

  As shown in FIGS. 1 and 2, an existing support column 51 provided on the installation surface 90 of the entrance / exit 91 can be used for the support 50 on which the holding member 60 is provided. By attaching the holding member 60 to the support column 51, the support column 51 functions as the support body 50. In addition, you may provide the support body 50 newly in the entrance / exit 91, without using the existing support | pillar 51. FIG. Further, a wall 52 is connected to the side of the column 51 opposite to the entrance / exit 91 to prevent water from entering.

  The holding member 60 is provided on the support body 50 on the side facing the waterproof member 10. As shown in FIG. 7, the holding member 60 has an inclined portion 61 that contacts the inclined surface 31 a of the engaging member 30 at the lower portion. The inclined portion 61 has an inclined surface 61 a that is inclined corresponding to the inclined surface 31 a of the engaging member 30. As the material of the holding member 60, for example, stainless steel can be used similarly to the engaging member 30. Moreover, the holding member 60 is attached to the support body 50 by, for example, a screw member.

  As described above, in the present embodiment, the inclined surface 31a of the engaging member 30 is positioned below the inclined portion 61 of the holding member 60 in a state where the elastic member 20 is not elastically deformed. For this reason, as shown in FIG. 8, in the state where the inclined portion 61 is in contact with the inclined surface 31a and the holding member 60 is engaged with the engaging member 30, a downward pressing force is applied to the waterproof member 10 in the vertical direction Av1. Therefore, the elastic member 20 is elastically deformed so as to contract in the vertical direction Av1. At the same time, since the inclined surface 31a is inclined so as to be directed upward from the waterproof member 10 toward the support body 50, a pressing force toward the support body 50 in the thickness direction At1 is also applied to the waterproof member 10. For this reason, the elastic member 25 is elastically deformed so as to contract in the thickness direction At1. In the present embodiment, the contact portion between the engagement member 30 and the holding member 60 is inclined, but the contact portion may not be inclined.

  Next, the operation at the time of installing the waterproof device 1 will be described. 9 to 11 are diagrams illustrating an operation when the waterproof device 1 is installed.

  As shown in FIG. 9, the operator tilts the waterproof member 10 so that the front surface 10 e of the waterproof member 10 faces the support body 50 and the elastic member 20 is disposed between the support body 50 and the installation surface 90. In the state, the waterproof member 10 is lowered to the installation surface 90. Next, while stepping on part B shown in FIG. 9 on the pressing surface 40a, the waterproof member 10 is rotated around the elastic member 20 so as to approach the support 50 so that the waterproof member 10 is vertical. Then, while stepping on the portion B, the engaging member 30 of the right side portion 10 </ b> R and the engaging member 30 of the left side portion 10 </ b> L are engaged with the holding member 60 of the support body 50, respectively, and the waterproof member 10 is fixed to the support body 50.

  During this installation operation, the operator steps on part B of the pressing surface 40a, so that a sufficient pressing force can be applied to the elastic member 20, whereby the elastic member 20 is compressed in the vertical direction Av1 together with the adjacent elastic member 25. Is done. That is, the elastic member 20 is elastically deformed so as to contract in the vertical direction Av1. Here, in FIG. 10 and FIG. 11, the waterproof device 1 in a state where the elastic member 20 is not elastically deformed is shown using a two-dot chain line, and the elastic member 20 is elastically deformed in the vertical direction Av1 using a solid line. The waterproof device 1 in a state of being cut is shown in a simplified manner. As indicated by a two-dot chain line in FIG. 10, the inclined surface 31 a of the engaging member 30 is located above the inclined portion 61 of the holding member 60 in a state where the elastic member 20 is not elastically deformed. However, as shown by a solid line in FIG. 10, the inclined surface 31 a of the engaging member 30 can be positioned below the inclined portion 61 of the holding member 60 by compressing the elastic member 20 in the vertical direction Av <b> 1. . If the operator removes his / her foot from the pressing surface 40a in this state, the pressing force in the vertical direction Av1 applied to the elastic member 20 disappears, so that the elastic member 20 is restored by the restoring force of the elastic member 20 as shown in FIG. 20 is elastically deformed so as to extend in the vertical direction Av1. Thereby, the inclined surface 31 a of the engaging member 30 contacts the inclined portion 61 of the holding member 60, and the engaging member 30 engages with the holding member 60. As described above, in a state where the elastic member 20 is not elastically deformed, the inclined surface 31 a of the engaging member 30 is located above the inclined portion 61 of the holding member 60. Even in the engaged state, as shown in FIG. 11, the elastic member 20 does not return to the original state, and the elastically deformed state is maintained so as to contract in the vertical direction Av <b> 1. Accordingly, a restoring force is always generated in the elastic member 20, and the pressing force in the vertical direction Av1 is always applied to the installation surface 90 by this restoring force, so that the water stoppage between the waterproof member 10 and the installation surface 90 is increased. Can keep good.

  At the same time, since the inclined surface 31a is inclined as described above, a pressing force is applied to the waterproof member 10 in the direction from the waterproof member 10 toward the support 50, that is, in the direction toward the support 50 in the thickness direction At1. Join. Since the elastic member 25 is provided on the front surface 10 e of the waterproof member 10 facing the support body 50, this pressing force is applied to the elastic member 25. Here, the dimension in the thickness direction of the elastic member 25 in a state where the elastic member 25 is not elastically deformed is the same as that of the waterproof member 10 and the support body 50 in a state where the inclined portion 61 of the holding member 60 is in contact with the inclined surface 31a of the engaging member 30. Greater than the distance between. For this reason, the elastic member 25 is elastically deformed so as to contract in the thickness direction At <b> 1 by this pressing force, and this elastically deformed state is maintained while the engaging member 30 is engaged with the holding member 60. Therefore, a restoring force is always generated in the elastic member 25, and a pressing force in the thickness direction At1 is always applied to the support 50 by the restoring force. Therefore, the water stoppage between the waterproof member 10 and the support 50 can be kept good.

  According to the waterproof device 1 according to the present embodiment, the pressing portion 40 capable of applying a force in the vertical direction Av1 is provided on the elastic member 20, and the pressing portion 40 intersects the vertical direction Av1 and extends upward. The pressing surface 40a is open. For this reason, when the waterproof member 10 is installed, the operator can easily apply a downward pressing force in the vertical direction to the elastic member 20 by pressing the pressing surface 40a. Therefore, even if the weight of the waterproof member 10 is light and sufficient weight cannot be applied to the elastic member 20 by its own weight, sufficient pressure can be applied to the elastic member 20. Thereby, the water stop property between the waterproofing member 10 and the installation surface 90 can be improved.

  The pressing portion 40 is provided at a position below the upper end portion 10 a of the waterproof member 10 and above the elastic member 20. That is, since the pressing portion 40 is provided within a range where the operator can work with his / her hands and feet, the operator can easily press the pressing surface 40a of the pressing portion 40 with his / her hands and feet. Therefore, the efficiency of the installation work of the waterproof member 10 can be improved.

  The pressing portion 40 is disposed at a position protruding from the elastic member 20 in a direction intersecting the vertical direction Av1 when viewed from the vertical direction Av1. For this reason, at the time of the installation work of the waterproof member 10, even if the waterproof member 10 is in an inclined state, it is easy for an operator to put a hand or a leg on the pressing portion 40. Therefore, the installation work of the waterproof member 10 can be performed more efficiently.

  The pressing portion 40 is composed of an auxiliary member (saddle material) 12 b attached to the waterproof member 10. Therefore, regardless of the dimension of the waterproof member 10 in the thickness direction At1, the sufficient size of the pressing surface 40a is ensured by appropriately adjusting the dimension of the auxiliary member 12b that is a separate member from the waterproof member 10. Can do. Regardless of the rigidity of the waterproof member 10, by appropriately adjusting the rigidity of the auxiliary member 12b, it is possible to ensure sufficient strength against the pressing force applied to the pressing surface 40a. Therefore, even when the dimension of the waterproof member 10 itself in the thickness direction At is small (the waterproof member 10 is thin), the pressing portion 40 has a sufficiently large pressing surface 40a and can have high strength. .

  Since the waterproof device 1 has a higher rigidity than the elastic member 20 and includes the reinforcing member 35 disposed along the elastic member 20 in the vertical direction Av1, the reinforcing member 35 causes excessive elastic deformation of the elastic member 20. Thus, buckling due to this elastic deformation can be prevented. Further, since the lower end 35b of the reinforcing member 35 is located below the middle position in the vertical direction Av1 of the elastic member 20 in a state where the elastic member 20 is not elastically deformed, the upper and lower sides of the elastic member 20 that are likely to buckle. The vicinity of the intermediate position in the direction Av1 can be reliably reinforced. Therefore, the waterproof property between the waterproof member 10 and the installation surface 90 by the elastic member 20 can be maintained for a long time.

  In addition, since the reinforcing member 35 is spaced apart from the elastic member 20 in the direction intersecting the vertical direction Av <b> 1, a gap is formed between the reinforcing member 35 and the elastic member 20. When this gap is not present, the elastic member 20 is restrained by the reinforcing member 35 along the vertical direction Av1 from the beginning of the elastic deformation, so that the lateral deformation caused by the elastic deformation in the vertical direction Av1 is suppressed. The elastic deformation itself in the vertical direction Av1 is difficult to perform. Therefore, by providing a gap between the reinforcing member 35 and the elastic member 20, the elastic member 20 can be appropriately elastically deformed in the vertical direction Av1. At the same time, significant deformation due to buckling or the like of the elastic member 20 can be suppressed by the reinforcing member 35 provided away from the elastic member 20.

  The waterproof member 10 has an engagement member 30 provided above the lower end portion 10 b of the waterproof member 10, and the engagement member 30 is elastic when engaged with the holding member 60 provided on the support body 50. The state in which the member 20 is elastically deformed in the vertical direction Av1 is maintained. Therefore, due to the engagement between the engagement member 30 and the holding member 60, the state of the elastic member 20 that is elastically deformed in the vertical direction Av1 by applying a sufficient pressing force by the pressing portion 40 can be maintained. Therefore, it is possible to maintain a state in which the water stoppage between the waterproof member 10 and the installation surface 90 is increased.

  Further, the inclined surface 31a of the engaging member 30 is inclined so as to go upward as it goes from the waterproof member 10 to the support body 50, and the elastic member 20 is elastically deformed in the inclined surface 31a of the engaging member 30. In the absence, it is located above the inclined portion 61 of the holding member 60. For this reason, when the inclined portion 61 of the holding member 60 is in contact with the inclined surface 31a of the engaging member 30, the direction from the waterproof member 10 toward the support body 50, that is, the thickness direction At1 of the waterproof member 10 is directed toward the support body 50. Thus, not only the pressing force that presses the waterproof member 10 but also the pressing force that presses the waterproof member 10 downward in the vertical direction Av1 is generated. Accordingly, a sufficient pressing force can be applied to the elastic member 20 provided at the lower end portion 10b of the waterproof member 10, and the state in which the elastic member 20 contracts in the vertical direction Av1 is maintained by this pressing force. The water stoppage between the waterproof member 10 and the installation surface 90 can be kept good. Further, since a restoring force is always generated in the elastic member 20, an upward pressing force in the vertical direction Av <b> 1 is applied to the waterproof member 10 to the restoring force, and the engagement member 30 and the holding member 60 are engaged. State is maintained. Therefore, it is possible to reliably prevent the waterproof member 10 from falling down. Further, the waterproof member 10 can be installed so as not to fall down by merely supporting the waterproof member 10 with respect to the support body 50 so that the inclined portion 61 of the holding member 60 contacts the inclined surface 31a of the engaging member 30. Therefore, the installation work becomes simple.

  Since the inclined surface 31 a of the engaging member 30 is provided at the upper end portion 10 a of the waterproof member 10, the waterproof device 1 is a part farthest from the lower end of the elastic member 20 that serves as a rotation fulcrum when the waterproof member 10 is lying down. The waterproof member 10 is prevented from falling at the upper end portion 10a of a certain waterproof member 10. Therefore, compared with the case where the inclined surface 31a is provided in another part, the force applied when the inclined portion 61 of the holding member 60 contacts the inclined surface 31a, that is, the engagement member 30 and the holding member 60 are engaged. The engagement force when combining can be reduced. In accordance with this, the elastic deformation amount of the elastic member 20 at the time of engagement can be reduced. Therefore, since the amount by which the operator steps on the pressing surface 40a can be reduced, workability can be improved.

  The inclined surface 31a of the engaging member 30 is provided on a side portion (right side portion 10R, left side portion 10L) in the width direction Aw1 of the waterproof member 10, which is a portion in contact with the support body 50 in the waterproof member 10. Since the waterproof member 10 is in contact with the support body 50 at the side portion in the width direction Aw1, the holding member 60 is provided by providing the inclined surface 31a at this side portion as compared with the case where the inclined surface 31a is provided at other portions. The force applied when the inclined portion 61 contacts the inclined surface 31a, that is, the engaging force when the engaging member 30 and the holding member 60 are engaged can be reduced. Moreover, since the elastic deformation amount of the elastic member 20 at the time of engagement can also be made small according to this, the amount that an operator steps on the pressing surface 40a can be made small, and workability can be improved.

  The inclined portion 61 of the holding member 60 has an inclined surface 61a that is inclined corresponding to the inclined surface 31a of the engaging member 30, and is in contact with the inclined surface 31a via the inclined surface 61a. The inclined portion 61 comes into contact with the inclined surface 31a by surface contact between the inclined surface 61a and the inclined surface 31a inclined corresponding to the inclined surface 31a, so that the inclined portion 61 can contact the inclined surface 31a more reliably and stably. . Therefore, once the inclined portion 61 comes into contact with the inclined surface 31a, the inclined portion 61 becomes difficult to be separated from the inclined surface 31a, and the engagement between the engaging member 30 and the holding member 60 is stably maintained.

  An elastic member 25 that can be elastically deformed is provided on the surface (front surface 10 e) of the waterproof member 10 that faces the support body 50. The elastic member 25 has a thickness dimension in a state where the elastic member 25 is not elastically deformed, and the distance between the waterproof member 10 and the support body 50 in a state where the inclined surface 61 a of the holding member 60 is in contact with the inclined surface 31 a of the engaging member 30. Bigger than. Therefore, in a state where the inclined portion 61 of the holding member 60 is in contact with the inclined surface 31a of the engaging member 30, the elastic member 25 is elastically deformed so as to contract in the thickness direction At1. By maintaining this elastically deformed state in the elastic member 25, the water stoppage between the waterproof member 10 and the support 50 can be kept good. Moreover, since the waterproof member 10 contacts the support body 50 through the elastic member 25, the support body 50 can be prevented from being damaged during the installation work of the waterproof member 10.

  The waterproof device 1 according to the present embodiment can be changed in configuration as follows, for example.

  FIG. 12 is a diagram illustrating an example of the configuration of the reinforcing member 35 of the waterproof device 1. As in the example illustrated in FIG. 12, the reinforcing member 35 may include an extending portion 36 that extends from the lower end 35 b of the reinforcing member 35 toward the elastic member 20. The extended portion 36 can intensively suppress excessive deformation of the elastic member 20 adjacent to the extended portion 36. In addition, the extending part 36 may be provided over the whole width direction Aw1 in the lower end 35b of the reinforcement member 35, and may be provided only in part. For example, the extending portion 36 may be provided only at both end portions in the width direction Aw1 at the lower end 35b of the reinforcing member 35.

  FIGS. 13 and 14 are diagrams illustrating examples of configurations of the engaging member (engaging portion) 30 and the holding member (engaged portion) 60 of the waterproof device 1. Both the engaging member 30 provided on the waterproof member 10 and the holding member 60 provided on the support body 50 have inclined surfaces, but both the engaging member 30 and the holding member 60 need to have inclined surfaces. There is no.

  In the example shown in FIG. 13, the support 50 is provided with an inclined portion 70 having an inclined surface 71. The inclined surface 71 is provided on the support 50 so as to face downward, and is inclined so as to go upward as it goes from the waterproof member 10 to the support 50. Further, the waterproof member 10 is provided with a contact portion 72 that contacts the inclined surface 71. Even in such a configuration, the force by which the inclined surface 71 provided on the support body 50 presses the contact portion 72 provided on the waterproof member 10 is the vertical direction Av1 and the thickness direction At1 due to the inclination of the inclined surface 71 described above. And decomposed. For this reason, when the contact portion 72 is in contact with the inclined surface 71, a downward pressing force in the vertical direction Av1 and a pressing force toward the support body 50 in the thickness direction At1 are applied to the waterproof member 10.

  In the example shown in FIG. 14, the waterproof member 10 is provided with an inclined portion 73 having an inclined surface 74. The inclined surface 74 is provided on the waterproof member 10 so as to face upward, and is inclined so as to go upward as it goes from the waterproof member 10 toward the support body 50. Further, the support 50 is provided with a contact portion 75 that contacts the inclined surface 74. Even in such a configuration, as in the example shown in FIG. 13, the force by which the contact portion 75 provided on the support body 50 presses the inclined surface 74 provided on the waterproof member 10 is the same as that of the inclined surface 74 described above. It is decomposed into the vertical direction Av1 and the thickness direction At1 by the inclination. For this reason, in the state where the contact portion 75 is in contact with the inclined surface 74, a downward pressing force in the vertical direction Av1 and a pressing force toward the support body 50 in the thickness direction At1 are applied to the waterproof member 10.

  As described above, one of the waterproof member 10 and the support 50 may be provided with an inclined portion having an inclined surface, and the other may be provided with a contact portion that contacts the inclined surface.

  FIG. 25 is a front view of the upper waterproof member 160 of the waterproof device 101. FIG. 26 is a right side view of the upper waterproof member 160. FIG. 27 is a sectional end view taken along line GG in FIG. The upper waterproof member 160 is different from the waterproof member 110 in that an elastic member 162 is provided instead of the elastic member 140 provided in the waterproof member 110. Otherwise, the upper waterproof member 160 has substantially the same configuration as the waterproof member 110. Therefore, portions having the same configuration as the waterproof member 110 are denoted by the same reference numerals, and detailed description thereof is omitted.

  An elastic member 162 that can be elastically deformed in the vertical direction Av <b> 2 is provided at the lower end portion 160 b of the upper waterproof member 160. The elastic member 162 is provided over the entire width direction Aw2 of the upper waterproof member 160. As described above, the lower end portion 160 b of the upper waterproof member 160 engages with the upper end portion 110 a of the waterproof member 110. The elastic member 162 is provided to seal the gap between the lower end portion 160b of the upper waterproof member 160 and the upper end portion 110a of the waterproof member 110 and prevent water from entering from the gap.

  FIG. 28 is a side view of the support 150R. 29 is a cross-sectional view taken along line HH in FIG. The support 150R (support 150) is formed to extend in the vertical direction Av2. Further, the support 150R is formed with a recess 151R (a recess 151) extending in the vertical direction Av2. The recess 151R includes a first wall surface 152R (first wall surface 152) and a second wall surface 153R (second wall surface 153) facing the first wall surface 152R. The dimension in the thickness direction At2 between the first wall surface 152R and the second wall surface 153R of the recess 151R is set to a dimension that allows the right end portion 111R of the waterproof member 110 to be fitted into the recess 151R. In the present embodiment, the waterproof member 110 is provided such that the back surface 110c of the waterproof member 110 provided with the pressing member 120R and the first wall surface 152R face each other, and the front surface 110d of the waterproof member 110 and the second wall surface 153R face each other. It fits into the recess 151. The dimension of the second wall surface 153R in the width direction Aw2 is set larger than the dimension of the first wall surface 152R in the width direction. As a result, the pressing member 120R and the second wall surface 153R are likely to overlap each other when viewed from the thickness direction At2, so that the force with which the pressing member 120R presses the waterproof member 110 can be surely directed toward the second wall surface 153R. . For example, aluminum can be used as the material of the support 150R.

  The support 150L (support 150) has a configuration in which the configuration of the support 150R described above is targeted on a plane perpendicular to the width direction Aw2. Therefore, the detailed description is abbreviate | omitted.

  As shown in FIGS. 15 and 16, the support 150 </ b> R and the support 150 </ b> L are provided on the installation surface 190 so that the recess 151 </ b> R and the recess 151 </ b> L face each other. In addition, a wall (not shown) for preventing flooding is connected to the support 150R on the opposite side of the recess 151R in the width direction Aw2. Similarly, a wall portion (not shown) for preventing flooding is connected to the opposite side of the recess 151L in the width direction Aw2 in the support 150L.

  Next, the operation | movement at the time of use of the waterproofing apparatus 101 is demonstrated with reference to FIG.15, FIG.30 and FIG.31. 30 and 31 are diagrams for explaining the operation when the waterproof device 101 is used.

  The operator inserts the waterproof member 110 from the upper part of the support 150 and lowers it on the installation surface 190. At this time, as shown in FIG. 30, the right end 111R of the waterproof member 110 is fitted into the recess 151R of the support 150R, and the left end 111L of the waterproof member 110 is fitted into the recess 151L of the support 150L. Further, the waterproof member 110 is arranged so that the gap in the width direction Aw2 between the right end portion 111R and the recess 151R and the gap in the width direction Aw2 between the left end portion 111L and the recess 151L are equal. At the time of insertion, the operation member 130 is positioned upward so that the engaging portion 122 of the pressing member 120 of the waterproof member 110 is at the retracted position P1. Next, the upper waterproof member 160 is inserted from the upper part of the support 150 and lowered to the waterproof member 110. At this time, as shown in FIG. 31, the lower end portion 160b of the upper waterproof member 160 and the upper end portion 110a of the waterproof member 110 are engaged and brought into close contact with each other. At the time of insertion, similarly to the waterproof member 110, the operation member 130 is positioned upward so that the engaging portion 122 of the pressing member 120 of the upper waterproof member 160 is at the retracted position P1. Subsequently, as shown in FIG. 15, on the pressing surface 144a of the waterproof member 110, for example, the operation member 130 of the waterproof member 110 is rotated downward while stepping on the C1 portion downward. Thereby, the waterproof member 110 is fixed to the support body 150 by the pressing member 120. Then, on the pressing surface 144a of the upper waterproof member 160, for example, the operation member 130 of the upper waterproof member 160 is rotated downward while stepping on the C2 portion downward. Thereby, the upper waterproof member 160 is fixed to the support body 150 by the pressing member 120. Thus, the installation of the waterproof device 101 is completed.

  During this installation operation, the operator steps down the pressing surface 144a of the waterproof member 110, so that a sufficient pressing force can be applied to the elastic member 140, whereby the elastic member 140 is compressed in the vertical direction Av2. That is, the elastic member 140 is elastically deformed so as to contract in the vertical direction Av2. In this state, since the waterproof member 110 is fixed to the support 150 by the pressing member 120, the elastic member 140 is maintained in an elastically deformed state so as to contract in the vertical direction Av2. Accordingly, a restoring force is always generated in the elastic member 140, and the pressing force in the vertical direction Av2 is always applied to the installation surface 190 by this restoring force, so that the water blocking property between the waterproof member 110 and the installation surface 190 is increased. Can keep good.

  Similarly, since the operator steps down the pressing surface 144a of the upper waterproof member 160, a sufficient pressing force can be applied to the elastic member 162, whereby the elastic member 162 is compressed in the vertical direction Av2. That is, the elastic member 162 is elastically deformed so as to contract in the vertical direction Av2. In this state, since the upper waterproof member 160 is fixed to the support 150 by the pressing member 120, the elastic member 162 is maintained in an elastically deformed state so as to contract in the vertical direction Av2. Accordingly, a restoring force is always generated in the elastic member 162, and the pressing force in the vertical direction Av2 is always applied to the upper end portion 110a of the waterproof member 110 by this restoring force, so that the upper waterproof member 160 and the waterproof member 110 It is possible to keep the water stoppage in between.

  Here, fixation of the waterproof member 110 and the upper waterproof member 160 to the support 150 by the pressing member 120 will be described. FIG. 32 is a diagram illustrating a state before the pressing member 120R is engaged with the first wall surface 152R in a state where the waterproof member 110 and the upper waterproof member 160 are fitted in the recess 151R, and (a) illustrates the operation member 130R. (B) shows the pressing member 120R. FIG. 33 is a diagram illustrating a state after the pressing member 120R is engaged with the first wall surface 152R, where (a) illustrates the operation member 130R and (b) illustrates the pressing member 120R.

  In the state shown in FIG. 32, since the engaging portion 122 of the eccentric cam 121 of the pressing member 120R is at the retracted position P1, the engaging portion 122 is not in contact with the first wall surface 152R. When the operation member 130R is rotated downward from this state, the eccentric cam 121 rotates downward around the rotation center O121, and the engaging portion 122 moves to the pressing position P2. In this state, as shown in FIG. 33, the engaging portion 122 is in contact with the first wall surface 152R, and the pressing surface 123 of the engaging portion 122 presses the first wall surface 152R. By the reaction force of the force that presses the first wall surface 152R, the pressing member 120R presses the waterproof member 110 toward the second wall surface 153R. As a result, the waterproof member 110 simultaneously presses the first wall surface 152R and the second wall surface 153R facing each other of the recess 151R by the pressing member 120R, and therefore, the engaging portion 122 of the pressing member 120R and the first wall surface are pressed. The waterproof member 110 is fixed to the support 150R by the frictional force between 152R and the frictional force between the waterproof member 110 and the second wall surface 153R.

  In the present embodiment, an elastic member 142R is provided on the front surface 110d of the right end portion 111R of the waterproof member 110 fitted in the recess 151R. For this reason, the waterproof member 110 presses the second wall surface 153R via the elastic member 142R. At this time, the elastic member 142R is sandwiched between the waterproof member 110 and the second wall surface 153R and is compressed in the thickness direction At2, that is, elastically deformed so as to contract in the thickness direction At2. In this state, since the waterproof member 110 is fixed to the support 150R, the elastic member 142R is kept elastically deformed so as to contract in the thickness direction At2. Accordingly, a restoring force is always generated in the elastic member 142R, and the pressing force in the thickness direction At2 is always applied to the waterproof member 110 and the second wall surface 153R by this restoring force, and thus the waterproof member 110 and the second wall surface 153R are applied. The water-stopping property between the two can be kept good.

  Further, as described above, in the state where the waterproof member 110 is fixed to the support 150R, the elastic member 140 is elastically deformed so as to contract in the vertical direction Av2, and thus the elastic member 140 has a restoring force in the vertical direction Av2. Occur. When an upward force in the vertical direction Av2 acts on the waterproof member 110 by this restoring force, an upward force in the vertical direction Av2 also acts on the pressing member 120R. That is, a force that moves the rotation center O121 of the eccentric cam 121 upward in the vertical direction Av2 acts on the pressing member 120R. In this case, since the engaging portion 122 of the eccentric cam 121 rotates relatively downward, it acts in a direction in which the engagement between the engaging portion 122 and the first wall surface 152R becomes stronger. Therefore, the waterproof member 110 is securely fixed by the support body 150R. In this embodiment, the waterproof member 110 is fixed to the support 150 by the pressing member 120. However, the waterproof member 110 cannot move in the vertical direction Av2 with respect to the support 150 using an external fixing means. You may be comprised so that it may become.

  In this embodiment, the pressing member 120 functions as an engaging portion provided above the lower end portion 110 b of the waterproof member 110, and the first wall surface 152 is an engaged portion provided on the support 150. Function as. That is, when the pressing member 120 is engaged with the first wall surface 152, the elastic member 140 is maintained in a state of being elastically deformed in the vertical direction Av2.

  According to the waterproof device 101 according to the present embodiment, the pressing portion 144 capable of applying a force in the vertical direction Av2 is provided on the elastic member 140, and the pressing portion 144 intersects the vertical direction Av2 and extends upward. And has a pressing surface 144a that is open. For this reason, when the waterproof member 110 is installed, the operator can easily apply a downward pressing force in the vertical direction Av2 to the elastic member 140 by pressing the pressing surface 144a. Therefore, even when the weight of the waterproof member 110 is light and sufficient weight cannot be applied to the elastic member 140 by its own weight, sufficient pressure can be applied to the elastic member 140. Thereby, the water stop property between the waterproof member 110 and the installation surface 190 can be improved.

  The pressing portion 144 is provided below the upper end portion 110 a of the waterproof member 110 and above the elastic member 140. That is, since the pressing portion 144 is provided within a range where the operator can work with his / her hands and feet, the operator can easily press the pressing surface 144a of the pressing portion 144 with his / her hands and feet. Therefore, the efficiency of installation work of the waterproof member 110 can be improved.

  The pressing portion 144 is disposed at a position protruding from the elastic member 140 in a direction intersecting the vertical direction Av2 when viewed from the vertical direction Av2. For this reason, at the time of installation work of waterproof member 110, it becomes easy for an operator to put a hand, a leg, etc. on press part 144. Therefore, the installation work of the waterproof member 110 can be performed more efficiently.

  The pressing portion 144 is composed of a collar member 147 attached to the waterproof member 110. For this reason, regardless of the dimension of the thickness direction At2 of the waterproof member 110 and the like, the sufficient size of the pressing surface 144a is ensured by appropriately adjusting the dimension of the collar member 147 that is a member different from the waterproof member 110. Can do. Regardless of the rigidity of the waterproof member 110, by appropriately adjusting the rigidity of the collar 147, it is possible to ensure sufficient strength against the pressing force applied to the pressing surface 144a. Accordingly, even when the dimension of the waterproof member 110 itself in the thickness direction At2 is small (the waterproof member 110 is thin), the pressing portion 144 has a sufficiently wide pressing surface 144a and can have high strength. .

  The waterproof member 110 has a pressing member 120 provided above the lower end portion 110 b of the waterproof member 110, and the pressing member 120 is elastic when engaged with the first wall surface 152 provided on the support 150. The state in which the member 140 is elastically deformed in the vertical direction Av2 is maintained. Therefore, due to the engagement between the pressing member 120 and the first wall surface 152, the state of the elastic member 140 that is elastically deformed in the vertical direction by applying a sufficient pressing force by the pressing portion 144 can be maintained. Therefore, it is possible to maintain a state in which the water stoppage between the waterproof member 110 and the installation surface 190 is increased.

  The pressing member 120 is provided on the waterproof member at a position facing the first wall surface 152 of the recess 151 in a state where the waterproof member 110 is fitted in the recess 151. For this reason, the force received when the pressing member 120 advances toward the first wall surface 152 and contacts the first wall surface 152 acts on the waterproof member 110 at a position facing the first wall surface 152 of the recess 151. Therefore, the force generated by the pressing member 120 can be transmitted without waste to the end 111 that is a portion of the waterproof member 110 that is disposed inside the recess 151. Therefore, since unnecessary force does not act on the waterproof member 110, damage and deformation of the waterproof member 110 due to this force can be prevented, and the force for operating the pressing member 120 can be reduced, and it is highly reliable and efficient. The water can be stopped.

  The pressing member 120 can be accommodated in the accommodating portion 112 formed in a concave shape with respect to the back surface 110 c of the waterproof member 110. For this reason, it becomes possible to ensure everything from the back surface 110c of the waterproof member 110 to the first wall surface 152 as a stroke of the advance / retreat operation of the pressing member 120. Therefore, the force with which the pressing member 120 presses the first wall surface 152 can be increased.

  The operation member 130 is attached to the accommodating portion 112 in which the pressing member 120 is accommodated. For this reason, the separation dimension between the operation member 130 and the pressing member 120 can be reduced. Therefore, the operating force of the operating member 130 can be transmitted to the pressing member 120 with a simpler structure.

  The accommodating portion 112 extends to the end portion 111 in the width direction Aw2 of the waterproof member 110 and opens at the end portion 111. For this reason, the pressing member 120 and the operation member 130 can be disposed in the housing portion 112 from the end portion 111. Therefore, the work of disposing the pressing member 120 and the operation member 130 on the waterproof member 110 can be performed efficiently.

  The elastic member 142 is provided on the front surface 110 d of the waterproof member 110 at a position facing the second wall surface 153 in a state where the waterproof member 110 is fitted in the recess 151. For this reason, the front surface 110 d of the waterproof member 110 is in contact with the second wall surface 153 via the elastic member 142. Therefore, it is possible to prevent the waterproof member 110 and the recess 151 from being damaged during the installation work of the waterproof member 110.

  The pressing member 120 has an eccentric cam 121 having a rotation center O121 in the recess 151, and the eccentric cam 121 rotates around the rotation center O121 from a state of being separated from the first wall surface 152. A pressing surface 123 for pressing 152 is provided. As described above, since the eccentric cam 121 rotates and moves forward and backward toward the first wall surface 152 of the pressing member 120, the configuration of the pressing member 120 can be simplified. At the same time, even when the distance between the waterproof member 110 and the first wall surface 152 is short and the operation stroke of the pressing member 120 is short, the first wall surface 152 can be pressed with an appropriate pressing force.

  The pressing member 120 has a support portion 124 that restricts the rotation range of the eccentric cam 121. For this reason, it is possible to prevent the eccentric cam 121 from rotating significantly and applying an excessive pressing force to the first wall surface 152. Further, the eccentric cam 121 has an engaging portion 122 that can press the first wall surface 152 and engage with the first wall surface 152. For this reason, when the engaging part 122 engages with the first wall surface 152, the state where the eccentric cam 121 presses the first wall surface 152 can be maintained.

  Since the engaging portion 122 of the eccentric cam 121 presses and engages the first wall surface 152 when the engaging portion 122 is at the pressing position P2 below the retracted position P1, the engaging portion 122 engages with the first wall surface 152. In this case, the eccentric cam 121 is rotated downward. Therefore, when an upward force is applied to the waterproof member 110 provided with the eccentric cam 121 in a state where the engaging portion 122 is engaged with the first wall surface 152, the upper portion of the eccentric cam 121 moves upward. Therefore, the force acts on the engaging portion 122 at the tip 121a of the eccentric cam 121 so that the eccentric cam 121 rotates further downward. Therefore, the engagement between the engaging portion 122 of the eccentric cam 121 and the first wall surface 152 can be made difficult to be released.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. Additions, omissions, substitutions, and other modifications can be made without departing from the spirit of the present invention.
