Description

[Technical field]

[0001] The present invention relates to a waterstop structure and a method for installing a waterstop body of a waterstop structure, and more particularly to a waterstop structure and a method for installing a waterstop body of a waterstop structure for preventing water from entering the inside of a structure from the outside. [Background technology]

[0002] 2. Description of the Related Art Conventionally, various techniques have been proposed relating to water stop devices that are installed to prevent the intrusion of water due to floods or the like.

[0003] For example, Patent Document 1 discloses a waterproofing device that includes a water shield plate that is adjacent to a floor surface on a wall or the like of a structure and covers at least a lower portion of an opening that opens to the side from the outdoor side while being in contact with the floor surface, a pressing member that is fixed to a mullion provided on the edge of the opening of the structure and presses the water shield plate at least toward the floor surface, and an elastically deformable sealing member that is provided on the water shield plate and seals between the water shield plate and the floor surface and between the water shield plate and the mullion. This waterproofing device places the water shield plate so as to cover the opening, and then presses the water shield plate toward the floor surface with the pressing member, and the water shield plate can be easily attached and removed, while the water shield plate can be held in a position covering the opening with a relatively simple configuration.

[0004] However, in the conventional waterproofing device as described in the above Patent Document 1, it is necessary to attach the pressing member while adjusting the position of the waterproofing plate so that the waterproofing plate is in proper contact with the floor surface and the mullion, so there is a demand for a waterproofing device that can be attached more quickly.

[0005] Patent Document 2 discloses a waterproof panel mounting device that supports a waterproof panel between a pair of mullions erected at an entrance or exit of a building, etc. The waterproof panel of this waterproof panel mounting device is equipped with a locking body consisting of a locking protrusion or locking claw, and the mullions are equipped with a locking body receiver consisting of a locked body or locking hole to which the locking body is locked or inserted and supported on the surface facing the waterproof panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0037] FIG. 1 is a schematic perspective view showing an installed state of a waterstop structure according to a first embodiment of the present invention.

[0038] 1, a waterstop structure 1 is attached to a pair of structures installed at a predetermined interval, such as a pair of wall surfaces 3 forming an entrance 2, and a floor surface 4. Specifically, with the side viewed from the direction of the arrow in FIG. 1 as the front, a pair of mounting members 11a, 11b in the form of approximately rectangular plates made of a watertight material such as stainless steel are attached vertically from the floor surface 4 via a packing 14 made of a rubber material or the like so as to be watertight to the wall surfaces 3 and the floor surface 4. In addition, a rectangular waterstop body 21 made of a watertight material such as resin is attached to the front side of the mounting members 11a, 11b.

[0039] Figure 2 is a schematic diagram showing the back side of the waterstop main body of the waterstop structure shown in Figure 1, and Figure 3 is a schematic diagram showing the waterstop main body of the waterstop structure shown in Figure 1, where (A) is a diagram showing the right side side, (B) is a diagram showing the flat side, and (C) is a diagram showing the bottom side.

[0040] 2 and 3(A)-(C) in addition to Fig. 1, a pair of bolt-type strikers 23a, 23b are provided as engaging bodies on both sides in the width direction at the upper part of the back side of the waterstop body 21 so as to protrude toward the mounting members 11a, 11b when the waterstop body 21 is attached to the mounting members 11a, 11b. In addition, the bolt-type strikers 23a, 23b are provided in positions in the parts facing the mounting members 11a, 11b so as to be engaged with later-described engaged bodies provided on the mounting members 11a, 11b. The effect of such a configuration will be described later.

[0041] Furthermore, a pair of claws 25a, 25b are provided on both sides in the width direction at the lower part on the back side of the waterstop body 21. In addition, these claws 25a, 25b are provided at positions in the parts facing the mounting members 11a, 11b so that they can be inserted into holes (described later) provided in the mounting members 11a, 11b. Furthermore, the claws 25a, 25b are generally inverted L-shaped in side view, and the tip parts 28a, 28b of the claws 25a, 25b are formed into a tapered shape with the part located on the waterstop body 21 side being cut obliquely. The effects of such a configuration will be described later.

[0042] Moreover, the waterstop body 21 has a hollow structure with both ends in the width direction being open. This makes the waterstop body 21 lighter than one having a solid structure, making it easier to handle. Furthermore, when using the waterstop structure 1 to prevent water from entering from the outside, the weight of the waterstop body 21 can be increased by introducing outside water into the internal space 27 of the hollow structure of the waterstop body 21, improving the stability of the waterstop structure 1 when in use.

[0043] Furthermore, waterstop material 26 made of rubber or the like is continuously provided on waterstop body 21 so as to form a substantial U-shape from the portion facing mounting members 11a, 11b on the back side of waterstop body 21 to the portion in contact with floor surface 4 on the bottom side of waterstop body 21. This improves the watertightness between waterstop body 21 and mounting members 11a, 11b and between waterstop body 21 and floor surface 4, thereby improving the reliability of waterstop structure 1.

[0044] Furthermore, handles 46a, 46b having inverted U-shaped gripping portions 47a, 47b are provided on the upper portion of the waterstop body 21. The gripping portions 47a, 47b of the handles 46a, 46b are each configured to be freely raised and lowered. When storing or after installing the waterstop body 21, it can be pushed downward as shown by the gripping portion 47b of the handle 46b. On the other hand, when transporting or installing the waterstop body 21, it can be pulled upward as shown by the gripping portion 47a of the handle 46a, and the waterstop body 21 can be lifted via the handles 46a, 46b, making it easier to transport and install the waterstop body 21.

[0045] FIG. 4 is a schematic diagram showing a connection portion of the plate members of the waterstop structure shown in FIG. 2, where (A) is an enlarged view of part A in FIG. 2, and (B) is a cross-sectional view taken along line BB of (A).

[0046] 1 to 3, and also FIG. 4, the waterstop body 21 is formed by connecting two substantially rectangular plates 22a and 22b at connecting portions 24a to 24e with screws 43a to 43d and plates 44a and 44b. Specifically, as shown in (A) and (B) of FIG. 4 for the connecting portion 24a, the plate 44a is placed on the bottom surface of the space 27a inside the hollow structure of the plate 22a, and the plate 44b is brought into contact with the top surface of the space 27b inside the hollow structure of the plate 22b. From this state, the screws 43a to 43d are inserted from the plate 22a side toward the plate 22b side through the plates 44a and 44b and the plate 22a and the plate 22b to fasten them together. The plate members 22a, 22b can be connected through openings 42a, 42b provided on the rear side of the plate members 22a, 22b near their connection. The openings 42a, 42b are covered by cover plates 41a, 41b to prevent water from entering. The connecting portions 24b to 24e are also configured in the same manner. In this way, the waterstop body 21 can be separated into the plate members 22a, 22b, so that the waterstop body 21 can be stored compactly when not in use and can be easily transported.

[0047] Furthermore, although not shown, if a water-stopping material or the like is provided on the connecting surfaces of the plates 22a and 22b, the water-stopping properties of the water-stop body 21 during use will be further improved, thereby improving the reliability of the water-stop structure 1.

[0048] Figure 5 is a schematic diagram showing the mounting member of the waterstop structure shown in Figure 1, where (A) is a view showing the front side, (B) is a view showing the right side, and (C) is an enlarged view of CC in (A).

[0049] Incidentally, since the mounting member 11b has a similar configuration to the mounting member 11a, the following description will focus on the mounting member 11a, and the description of the mounting member 11b will be omitted.

[0050] 1 and 5(A) to 5(C) together, a rotating latch 13a that is an engaged body that engages with the bolt-type striker 23a of the waterstop body 21 described above is provided on an upper portion of the mounting member 11a on the wall surface 3 side. The rotating latch 13a has a recess 31a that is open upward, and a locking mechanism 32a that is substantially U-shaped and rotates in the vertical direction around a rotation center 33a. The specific operation of the bolt-type striker 23a and the rotating latch 13a will be described later, but the bolt-type striker 23a inserted into the recess 31a of the rotating latch 13a can be latched by being covered from above by the locking mechanism 32a.

[0051] Furthermore, the upper end of the mounting member 11a is provided with a notch 16a that matches the recess of the rotary latch 13a.

[0052] Furthermore, a rectangular hole 15a is provided in the lower part of the mounting member 11a in the portion facing the waterstop body 21. As described above, the claw portion 25a of the waterstop body 21 can be inserted into this hole 15a. The effect of this configuration will be described later.

[0053] Next, a specific method for attaching the waterstop body 21 to the mounting members 11a and 11b will be described.

[0054] Figure 6 is a schematic right side view showing the first half of the installation process when attaching the waterstop body of the waterstop structure shown in Figure 1 to a mounting member, where (1) is a diagram showing the process of preparing the waterstop body, (2) is a diagram showing the process of inserting the claw portion of the waterstop body into the hole portion of the mounting member, and (3) is a diagram showing the process of raising the waterstop body.

[0055] Furthermore, since the relationship between the waterstop body 21 and the mounting member 11a is similar to the relationship between the waterstop body 21 and the mounting member 11b, the following explanation will focus on the relationship between the waterstop body 21 and the mounting member 11a, and explanations of the waterstop body 21 and the mounting member 11b will be omitted.

[0056] First, referring to FIG. 6(1), the waterstop body 21 is carried from a storage location or the like to the vicinity of the mounting member 11a that has been attached to the wall surface 3 in advance.

[0057] Next, referring to FIG. 6(2), the waterstop body 21 is lifted so that its upper side is inclined toward the outdoors. From this state, the claw portion 25a is inserted into the hole portion 15a of the mounting member 11a, and the portion 29a of the tip portion 28a of the claw portion 25a on the waterstop body 21 side is hooked on the opening vicinity 19a of the hole portion 15a. At this time, the lower portion 39 of the waterstop material 26 attached to the back side of the waterstop body 21 is pressed against the mounting member 11a. At this time, if the claw portion 25a is pushed all the way to the base in one go to hook the claw portion 25a into the hole portion 15a, there will be no play between the claw portion 25a and the hole portion 15a, and the waterstop material 26 may be excessively pressed against the mounting member 11a and damaged. However, as described above, the claw portion 25a is substantially inverted L-shaped, and the portion 29a of the tip portion 28a of the claw portion 25a on the waterstop body 21 side is tapered by being cut diagonally, so that the portion 29a of the tip portion 28a of the claw portion 25a on the waterstop body 21 side can be hooked on the vicinity 19a of the opening of the hole 15a simply by inserting the claw portion 25a lightly diagonally downward into the hole 15a. This creates play between the claw portion 25a and the hole 15a, so that the waterstop material 26 can be prevented from being plastically deformed and damaged by excessive pressing of the waterstop material 26 against the mounting member 11a.

[0058] 6(3), the waterstop body 21, which is inclined upward toward the outdoor side, is raised toward the mounting member 11a using the contact portion 30 between the claw portion 25a of the waterstop body 21 and the hole portion 15a of the mounting member 11a as a reference for alignment. At that time, the waterstop body 21 is raised in a slightly arc-like trajectory as shown by the arrow, with the contact portion 30 between the claw portion 25a of the waterstop body 21 and the hole portion 15a of the mounting member 11a as a fulcrum, which makes the raising operation easier.

[0059] Fig. 7 is a schematic right side view showing the latter half of the installation process when the waterstop body of the waterstop structure shown in Fig. 1 is installed to the installation member, (1) is a diagram showing the process of raising the waterstop body to an upright state, and (2) is a diagram showing the process of pushing the waterstop body downward from above. Also, Fig. 8 is a schematic view seen from the front side showing the positional relationship of the bolt-type striker and the rotating latch corresponding to the installation process of the waterstop structure shown in Fig. 7.

[0060] Referring to Fig. 7(1), while maintaining the contact state between the claw portion 25a of the waterstop body 21 and the mounting member 11a, the waterstop body 21 is further raised toward the mounting member 11a until the waterstop body 21 is in an upright state. Then, the waterstop material 26 on the back side of the waterstop body 21 is pressed against the mounting member 11a, and the cylindrical portion 35a of the bolt-type striker 23a of the waterstop body 21 is positioned above the notch 16a of the mounting member 11a and the recess 31a of the rotating latch 13a. In this state, referring also to Fig. 8(1), the rotating latch 13a is in an open state with the U-shaped opening portion of the locking mechanism 32a facing diagonally upward, and the cylindrical portion 35a of the bolt-type striker 23a is in contact with the U-shaped opening portion of the locking mechanism 32a of the rotating latch 13a.

[0061] Next, referring to FIG. 7(2), when the waterstop body 21 is pushed vertically downward from the state of FIG. 7(1), the cylindrical portion 35a of the bolt-type striker 23a of the waterstop body 21 descends so as to be pushed into the notch portion 16a of the mounting member 11a and the recessed portion 31a of the rotating latch 13a. At that time, referring to FIG. 8(2), the cylindrical portion 35a of the bolt-type striker 23a pushes down the U-shaped open portion of the locking mechanism 32a, so that the locking mechanism 32a starts to rotate in the direction of the arrow around the rotation center 33a. When the insertion of the cylindrical portion of the bolt-type striker 23a into the recessed portion 31a of the rotating latch 13a is completed, referring to FIG. 8(3), the locking mechanism 32a of the rotating latch 13a covers and latches a part of the cylindrical portion 35a of the bolt-type striker 23a from above. This prevents the waterstop body 21 from moving upward.

[0062] In addition, by pushing down the waterstop body 21, the claw portion 25a also descends inside the hole portion 15a. As a result, the claw portion 25a is inserted deeper into the hole portion 15a, and the claw portion 25a and the hole portion 15a become auxiliary fixing means for the waterstop structure 1, and the waterstop body 21 is prevented from moving in the depth direction (toward the outdoors) relative to the mounting member 11a.

[0063] Moreover, the water stop material 26 of the water stop plate body 21 is pressed against the floor surface 4 and the mounting member 11a, thereby preventing the intrusion of water from the outside.

[0064] FIG. 9 is a schematic plan view showing the engaged state between the bolt-type striker and the rotary latch shown in FIG. 8(3).

[0065] 9, the diameter α of the shape formed by the recess 31a of the rotary latch 13a and the locking mechanism 32a in the engaged state is designed to be smaller than the diameter β of the head 36a of the bolt-type striker 23a, so that the bolt-type striker 23a does not fall out in the depth direction (to the outdoors). In this way, the locking mechanism 32a of the rotary latch also functions as a means for preventing the bolt-type striker 23a from falling out. This eliminates the risk of the waterstop body 21 falling out of the mounting member 11a to the outdoors.

[0066] By adopting the above-mentioned configuration, watertightness can be achieved. board The amount of work required to attach the main body 21 to the mounting member 11a is reduced. Also, the waterstop main body 21 can be attached to the mounting member 11a simply by pushing the bolt-type striker 23a into the rotating latch 13a. Furthermore, the contact portion 30 between the claw portion 25a and the hole portion 15a can be used as a reference for aligning the waterstop main body 21 with the mounting member 11a. These features enable the waterstop structure 1 to be quickly attached.

[0067] Furthermore, by providing auxiliary fixing means such as the claws 25a and the holes 15a, the mounting state of the waterstop body 21 to the mounting member 11a becomes more stable, thereby improving the reliability of the waterstop structure 1.

[0068] Furthermore, by providing a locking mechanism 32a or other means for preventing the device from falling out, water can be stopped after installation. board Since unintentional movement of the main body 21 is prevented, the waterstop structure 1 can be quickly and stably attached.

[0069] Furthermore, by using the above-described installation process, the waterstop main body 21 can be attached to the mounting member 11a in a sequential manner from bottom to top, making it easier to align the waterstop main body 21 when attaching it to the mounting member 11a, and enabling the waterstop structure 1 to be installed quickly.

[0070] Furthermore, in the state where the waterstop body 21 is attached to the mounting member 11a as shown in (2) of Fig. 7, the claw portion 25a is not in contact with the wall surface 3 side of the mounting member 11a inside the hole portion 15a, so that the claw portion 25a has a range of movement in the direction of the wall surface 3. Also, as shown in Fig. 9, the diameter of the cylindrical portion 35a of the bolt-type striker 25a is smaller than the size α of the diameter of the shape formed by the recess 31a of the rotation latch 13a and the lock mechanism 32a in the engaged state, so that the bolt-type striker 23a has a range of movement in the direction of the wall surface 3. As a result, when the waterstop structure 1 is used, the water pressure applied to the waterstop body 21 from the front side shown in Fig. 1 as the external water level rises compresses the waterstop material 26, and the waterstop body 21 is firmly pressed against the mounting member 11a, thereby increasing the waterstop performance. In addition, the weight of the waterstop body 21 increases as water is introduced into the space 27 inside the hollow structure of the waterstop body 21, and the waterstop material 26 is pressed more firmly against the floor surface 4. This makes it possible to reliably prevent water from entering from the outside.

[0071] FIG. 10 is a schematic diagram showing the back side of a waterstop body of a waterstop structure according to the second embodiment of the present invention, and corresponds to FIG.

[0072] Incidentally, since the configurations of the waterstop structure 51 and the waterstop body 61 according to this embodiment are basically the same as those of the first embodiment, the description will not be repeated here, but the differences will be mainly described.

[0073] 10, a waterstop body 61 of the waterstop structure 51 is made up of two substantially rectangular plates 62a and 62b, similar to the waterstop body 21 of the first embodiment. However, the plates 62a and 62b are not connected by screws, plates, or the like, and are configured to be always separable.

[0074] Bolt-type strikers 63a, 63b having a configuration similar to that of the bolt-type strikers 23a, 23b of the first embodiment are provided on both sides in the width direction in an upper part on the rear side of the waterstop body 61 (an upper part on the rear side of the plate material 62a). Also, claw portions 65e, 65f having a configuration similar to that of the claw portions 15a, 15b of the first embodiment are provided on both sides in the width direction in a lower part on the rear side of the waterstop body 61 (a lower part on the rear side of the plate material 62b).

[0075] Furthermore, a pair of claws 65a, 65b are provided on both sides in the width direction at a lower portion on the rear side of the plate material 62a of the waterstop body 61. Furthermore, a pair of claws 65c, 65d are provided on both sides in the width direction at an upper portion on the rear side of the plate material 62b. The shapes and attachment states of the claws 65a to 65d are similar to those of the claws 65e, 65f.

[0076] Furthermore, waterstop body 61 is continuously provided with waterstop materials 66a, 66b having a similar configuration to waterstop material 26 in a portion corresponding to the portion where waterstop material 26 of the first embodiment is provided. Although not shown, waterstop material may be further provided on the connecting surface between plate material 62a and plate material 62b in order to improve the waterstop property of waterstop body 61. The effect of configuring waterstop body 61 in this way will be described later.

[0077] Figure 11 is a schematic diagram showing a mounting member of a waterstop structure according to a second embodiment of the present invention, and corresponds to Figure 5, where (A) is a diagram showing the front side, (B) is a diagram showing the right side, and (C) is an enlarged view of CC of (A).

[0078] Incidentally, the configuration of the mounting member 71a in this embodiment is basically the same as that of the first embodiment, and therefore the description will not be repeated here, but will focus on the differences. Also, the mounting members in this embodiment are a pair as in the first embodiment, but since they have the same configuration, the description will be focused on one mounting member 71a, and the description of the other side will be omitted.

[0079] 11(A) and (B) in addition to Fig. 10, a rotating latch 73a equivalent to the rotating latch 13a of the first embodiment is provided on an upper portion of the wall surface 3 side of the mounting member 71a of the waterstop structure 51. The structure and mounting state of the rotating latch 73a are similar to those of the rotating latch 13a of the first embodiment, and the rotating latch 73a is provided with a lock mechanism 82a as shown in Fig. 11(C). In addition, a hole 75e having a similar configuration to the hole 15a of the first embodiment is provided on a lower portion of the mounting member 71a in a portion facing the waterstop body 61.

[0080] Furthermore, holes 75a, 75c into which the claws 65a, 65c of the waterstop body 61 can be inserted are provided near the center of the mounting member 71a in a portion facing the waterstop body 61. The structure of each of the holes 75a, 75c is similar to that of the hole 75e. The effect of configuring the mounting member 71a in this way will be described later.

[0081] Next, a specific method for attaching the waterstop body 61 to the attachment member 71a will be described. Here again, the attachment member 71a side will be mainly described, and the other side having the same configuration will not be described.

[0082] Figure 12 is a schematic right side view showing the installation process when attaching the plate located below the waterstop body shown in Figure 10 to the mounting member shown in Figure 11, where (1) is a diagram showing the process of preparing the plate, (2) is a diagram showing the process of inserting the claw portion of the plate into the hole portion of the mounting member, and (3) is a diagram showing the process of pushing the plate from above downward.

[0083] First, referring to FIG. 12(1), the plate material 62b of the waterstop body 61 is carried from a storage location or the like to the vicinity of the mounting member 71a that has been attached to the wall surface 3 in advance.

[0084] Next, referring to FIG. 12(2), the plate material 62b is lifted upward, and the claws 65c, 65e are lightly inserted diagonally downward into the holes 75c, 75e of the mounting member 71a. At this time, due to the same relationship as the relationship between the claws 25a, the holes 15a, and the water-stopping material 26 described in the first embodiment, the portions 69c, 69e of the tip portions 68c, 68e of the claws 65c, 65e on the plate material 62b side can be hooked on the openings 79c, 79e of the holes 75c, 75e, and play is generated between the claws 65c, 65e and the holes 75c, 75e. This makes it possible to prevent the water-stopping material 66b from being plastically deformed and damaged due to excessive pressing of the water-stopping material 66b against the mounting member 71a.

[0085] Furthermore, referring to Fig. 12(3), when the plate material 62b is pushed vertically downward from the state of Fig. 12(2), the claws 65c, 65e descend inside the holes 75c, 75e. As a result, the claws 65c, 65e are inserted deeper into the holes 75c, 75e, and the claws 65c, 65e and the holes 75c, 75e function as auxiliary fixing means for the waterstop structure 51, preventing the plate material 62b (the lower part of the waterstop body 61) from moving in the depth direction (toward the outdoors) relative to the mounting member 71a.

[0086] Figure 13 is a schematic right side view showing the installation process when attaching the plate located on the upper side of the waterstop body shown in Figure 10 to the mounting member shown in Figure 11, where (1) is a diagram showing the process of raising the plate, (2) is a diagram showing the process of raising the plate to an upright position, and (3) is a diagram showing the process of pushing the plate from above downward.

[0087] Referring to (1) of FIG. 13, the plate material 62a of the waterstop body 61 is transported from a storage location or the like to the vicinity of the mounting member 71a on which the plate material 62b is installed. Next, the plate material 62a is lifted so that its upper side is inclined toward the outdoors, and then the claw portion 65a is inserted into the hole portion 75a of the mounting member 71a. At this time, because of the same relationship as the relationship between the claw portion 25a, the hole portion 15a, and the waterstop material 26 described in the first embodiment, the portion 69a of the tip portion 68a of the claw portion 65a on the plate material 62a side can be hooked on the opening vicinity 79a of the hole portion 75a by simply inserting the claw portion 65a diagonally downwardly into the hole portion 75a, and a play is created between the claw portion 65a and the hole portion 75a. This makes it possible to prevent the waterstop material 66a from being plastically deformed and damaged due to excessive pressing of the waterstop material 66a against the mounting member 71a.

[0088] Next, as explained in the first embodiment, using the contact portion 80 between the claw portion 65a of the plate material 62a and the hole portion 75a of the mounting member 71a as a reference for alignment, the plate material 62a, which is inclined upward toward the outdoor side, is pulled up toward the mounting member 71a in a trajectory indicated by the arrow.

[0089] 13(2), while maintaining the contact state between the claw portion 65a of the plate material 62a and the mounting member 71a, the plate material 62a is further raised toward the mounting member 71a until the plate material 62a is in an upright state. Then, the water-stopping material 66a of the plate material 62a is pressed against the mounting member 71a, and the bolt-type striker 63a of the plate material 62a is positioned above the mounting member 71a and the rotating latch 73a.

[0090] Next, referring to Fig. 13(3), when the plate material 62a is pushed vertically downward from the state of Fig. 13(2), the bolt-type striker 63a of the plate material 62a descends, and the rotary latch 73a operates in the same manner as the rotary latch 13a of the first embodiment. As a result, a part of the upper part of the cylindrical portion 85a of the bolt-type striker 63a is latched by the lock mechanism 82a of the rotary latch 73a. This prevents the waterstop body 61 from moving upward and tipping over to the outdoors.

[0091] Moreover, by pushing down the plate 62a, the claw 65a also descends inside the hole 75a. As a result, the claw 65a is inserted deeper into the hole 75a, and the claw 65a and the hole 75a serve as auxiliary fixing means for the waterstop structure 51, preventing the plate 62a (waterstop body 61) from moving in the depth direction (toward the outdoors) relative to the mounting member 71a.

[0092] By adopting the above-mentioned configuration, it becomes possible to attach and detach each of the plate members 62a and 62b constituting the waterstop body 61. board Since the main body 61 can be easily separated into the plate members 62a and 62b, the waterstop main body 61 can be stored compactly when not in use and can be easily transported.

[0093] Furthermore, since the auxiliary fixing means is made up of a total of three pairs of claws 65a to 65f and holes 75a, 75c, 75e (not shown), the installation state of the waterstop structure 51 becomes more stable.

[0094] In the above-described embodiments, the waterstop body is substantially rectangular in shape, but the waterstop body is not limited to this and may be trapezoidal or other shapes.

[0095] Furthermore, in each of the above embodiments, the waterstop body is made of resin, but this is not limited to this and it may be made of other materials such as metal or rubber as long as it has watertight properties.

For example, the portion corresponding to the head portion may have another shape, such as a sphere, and the portion corresponding to the cylindrical portion may have another shape, such as a square prism or a triangular prism.

[0104] Furthermore, in each of the above embodiments, the engaging body and the engaged body are composed of a bolt-type striker and a rotating latch, and are attached at a specific position, but this is not limited to this. Anything above half the height of the waterstop body and the mounting member is included in the upper part. Also, if the engaging body can be inserted into the engaged body from above, it may be provided at any position on the waterstop body and the mounting member depending on what is used as the engaging body and the engaged body. For example, if the rod-shaped through hole and receiving bracket are used, the receiving bracket can be provided on the front side of the mounting member, and a through hole can be provided at a position on the waterstop body corresponding to it.

[0105] Furthermore, in the above first embodiment, the auxiliary fixing means is provided, but the auxiliary fixing means may be omitted.
