Description

The present invention relates to a water stop device.

Conventionally, there are known water stop devices (water stop plates, waterproof plates) that are installed in the openings of a structure to prevent water from entering the inside of the structure. For example, a structure (building or the like) is provided with an opening that communicates the outside (outdoor side) and the inside (indoor side). When the inside of the opening is expected to be flooded due to torrential rain or flooding of the river, the water stop device closes the opening by installing, for example, a plate-shaped waterproof plate in advance to prevent flooding. To prevent. Such a water stop plate (water stop device) is often stored in a warehouse or the like in normal times (when there is no risk of flooding). When storing the water stop plate, the water stop member (for example, elastic parts such as rubber, elastomer, flexible resin, etc.) provided on the water stop plate is deformed in order to improve the closing property (adhesion) of the opening. It is desirable to store it in a state where it is difficult to prevent or deteriorate, and it is desirable that it can be stored in a small space. Therefore, a storage tool that can store the water stop plate in such a state has been proposed.

JP-A-2017-14865

The width of the opening to which the water stop plate is applied (for example, the distance between the left and right mullions constituting the opening) varies depending on the form of the structure (for example, the building). On the other hand, the water stop plate, which is desirable to be quickly manually transported between the storage place and the installation place, is preferably lightweight, and is less deformed even when water pressure is applied when the water is stopped, and the water stoppage is the specified value. A predetermined strength (rigidity) is required so as not to fall below. Therefore, the width of the water stop plate (the length in the width direction of the opening) may be limited. Therefore, when closing an opening with an opening width wider than the width of the water stop plate, a plurality of water stop plates are provided by installing a center pillar that can be easily attached and detached at the center position in the width direction, for example. May be placed (continuously installed). When the center pillar is used in this way, it is necessary to store the center pillar separately when storing the water stop plate. Therefore, if the storage form can be improved, such as the storage work becoming complicated and the storage space increasing, the usability is improved and it is meaningful.

The present invention has been made in view of the above circumstances, and one of the objects of the present invention is to provide a water stop device capable of storing a central pillar together with a water stop plate in a space-saving manner.

In order to achieve the above object, the water blocking device according to the present embodiment is arranged along the width direction of the opening on the outside of the opening communicating the inside and the outside of the structure, and the opening It is possible to connect a plurality of water stop plates capable of closing the opening from the floor surface forming a part of the above to a predetermined height, and the inner end region of the plurality of water stop plates arranged adjacent to each other. A center pillar that can be attached to and detached from the floor surface, and the water stop plate or at least one of the center pillars is provided with the center pillar removed from the floor surface. A support portion supported by a part of the plate is provided. According to this configuration, for example, when the water stop plate is stored, the center pillar can be stored together, and the water stop plate and the center pillar can be substantially integrated, so that the storage space can be saved. it can.

Further, the support portion of the water stop device according to the present embodiment may be, for example, a hook member provided on a part of the side surface of the middle pillar and hooked on the upper surface of the water stop plate. According to this configuration, for example, the center pillar can be supported by the water stop plate with a simple structure, and the center pillar can be easily attached to and detached from the water stop plate, and the work during installation and storage of the water stop device is performed. Efficiency can be improved.

Further, the hook member of the water stop device according to the present embodiment has, for example, a first posture that projects in the lateral direction of the middle pillar and can be hooked on the upper surface of the water stop plate, and a side surface of the middle pillar. It may be provided with a second posture housed so as to overlap and a moving mechanism for moving between them. According to this configuration, for example, when the center pillar is used, that is, when the water stop plate is installed, if the hook member is moved to a second posture in which the hook member is housed so as to overlap the side surface of the center pillar, for example, the water stop plate can be installed. It is possible to prevent interference with structures (for example, doors, etc.) around the water stop plate. Further, when a pedestrian passes over the water stop plate when the water stop plate is installed, it is unlikely to interfere with the hook member and hinder the passage. Further, if the hook member is moved to the first posture and protrudes from the lateral side of the middle pillar, it can be easily hooked on the upper surface of the water stop plate and stored.

Further, the water stop device according to the present embodiment further includes, for example, a stand member that maintains and holds a standing posture along the wall surface when the water stop plate is not used, and the stand member is such that when not in use. When the water stop plate is supported in an upright posture along the wall surface, a gap is formed between the wall surface and the water stop plate so as to interpose at least the center pillar supported by the water stop plate. You may do so. According to this configuration, for example, the center pillar can be stored by utilizing the space between the water stop plate and the wall surface, which are stored in an upright posture by the stand member. Further, since the central pillar can be stored in a state of being covered with a water stop plate, the central pillar does not protrude toward the passage space side at the storage location, and it is possible to prevent the central pillar from obstructing the passage.

Further, the central pillar of the water stop device according to the present embodiment has, for example, a detachable posture maintaining member that maintains a standing posture when installed on the floor surface, and further, the removed posture maintaining member. May be provided with a holding structure for holding. According to this configuration, for example, fastening parts (for example, bolts) for fixing the middle pillar to the floor surface, leg members for stabilizing the standing posture of the middle pillar, and fastening for fixing the leg members to the middle pillar. Since the posture maintaining member such as a member is held by, for example, a part of the center pillar when not in use, it is possible to easily prevent the posture maintaining member from being lost or damaged.

Further, the posture maintaining member of the water stop device according to the present embodiment is, for example, the first surface of the middle pillar that comes into contact with the water stop plate when the middle pillar is supported by the water stop plate. It may be fixed to a different second surface. According to this configuration, for example, the posture maintaining member can be easily held and stored while the center pillar is supported by the water blocking plate.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to this embodiment. In addition, the components in the embodiments shown below include those that can be easily replaced by those skilled in the art, or those that are substantially the same.

The water stop device of the present embodiment includes at least a water stop plate and a center pillar. The water stop plate is a plate-shaped component that can be arranged along the width direction of the opening on the outside of the opening that communicates the inside and the outside of the structure. One or a plurality of water stop plates are used depending on the opening width of the opening, and can be installed along the width direction of the opening. The water stop plate can close the opening from the floor surface forming a part of the opening to a predetermined height, and prevents or reduces rainwater or the like from entering the inside of the opening. When a single water stop plate is used, both ends of the water stop plate in the width direction are brought into close contact with a pair of left and right frame members (for example, "mullion" in the case of a building) that form an opening, and the water stop plate is used. The water stopping performance is ensured by bringing the lower surface of the mullion into close contact with the floor. When a plurality of water stop plates are arranged in the width direction and used, a middle pillar (intermediate pillar) is erected from the floor surface in the width direction of the opening, for example, in the center. Then, while the lower surface of the water stop plate is brought into close contact with the floor surface, one end surface is brought into close contact with the frame member of the opening in the width direction of the water stop plate, and the other end face is brought into close contact with the middle pillar. Similarly, while the lower surface of the adjacent water stop plate is brought into close contact with the floor surface, one end face in the width direction is brought into close contact with the middle pillar, and the other end face is brought into close contact with the frame member on the opposite side. As a result, the same water stopping performance can be obtained even for a wide opening. When the opening width of the opening is wider, the number of water stop plates arranged in the width direction can be increased by using a plurality of middle columns, and the same water stop can be realized.

In the embodiment described below, a water stop device having a specification in which a plurality of water stop plates (for example, two sheets) are installed using a middle pillar (for example, one) will be described, and a storage mode of the water stop device will be described. ..

FIG. 1 is a front view showing an example of a water stop plate 10 of the water stop device according to the embodiment, and is a view seen from the outside (outdoor side) at the time of installation. Further, FIG. 2 is a front view showing an example in which a plurality (for example, two) of water stop plates 10 are arranged and installed in an opening 12 of a structure (for example, a building), and is viewed from the outside (outdoor side). It is a figure. FIG. 3 is a view taken along the line AA of the water stop plates 10 installed in a plurality of arrangements shown in FIG. 2 (partially omitted and partially cross-sectional). FIG. 4 is a side view showing an example of a center pillar 14 used when a plurality of water stop plates 10 are arranged and installed. Further, FIG. 5 is a BB arrow view (partial cross section) of the water stop plates 10 installed in a plurality of arrangements shown in FIG.

In the embodiment, the "outside" is the side where rainwater or the like flows toward the opening 12 due to torrential rain, flooding of a river, or the like, based on the opening 12 of a structure (for example, a building). , "Inside" means the opposite side of the "outside" across the opening 12, that is, the structure side from the opening 12. When the opening 12 is formed in a building, the "outside" may be expressed as "outdoor side" and the "inside" may be expressed as "indoor side". Therefore, in each figure, the "inside / outside direction" is the direction connecting the outside (outdoor side) and the inside (indoor side) with the opening 12 in between, and the "width direction" is orthogonal to the inside / outside direction and opens. The pair of frame members (in the case of a building, "square") constituting the portion 12 are installed apart from each other, and the "vertical direction" is a direction orthogonal to the inside / outside direction and the width direction.

First, the configuration of the water stop plate 10 will be described. As shown in FIGS. 1 and 2, the water stop plate 10 is a long plate-shaped component that can be installed along the width direction of the opening 12, and the length in the width direction is the length in the width direction of the opening 12. It is set longer than that. When a plurality of water stop plates 10 are arranged and used in the width direction as in the present embodiment, the length in the width direction at the time of arrangement is set to be longer than the length in the width direction of the opening 12. Further, the height of the water stop plate 10 in the vertical direction is preferably set to a height at which the user can sufficiently straddle the water stop plate 10 in the installed state, that is, in the standing state, for example. , 40 to 60 cm is preferable. Therefore, even when the water stop plate 10 is installed, the user can go back and forth inside and outside the opening 12 by straddling the water stop plate 10. The water stop plate 10 preferably has a strength that can withstand the water pressure of rainwater received by the outer surface 10a at the time of installation, and has a weight that can be carried by the user alone. For example, aluminum or an aluminum alloy. , Stainless steel, etc., made of lightweight and strong material. Further, in another embodiment, the water blocking plate 10 may have a form in which the frame defining the outer shape is formed of metal and the inside of the frame is closed with a water-impervious material. As the water-impervious material, for example, a foaming material or a sheet can be used. In this case, it is possible to contribute to the weight reduction of the water stop plate 10. Further, the water stop plate 10 may be provided with a handle 10b on the upper surface, for example, or may be gripped on the outer surface 10a or the inner surface 10c (see FIG. 3) so that the user can easily carry out the transportation work and the installation work. A handle or unevenness may be provided.

As shown in FIG. 3, when the outer surface 16a or the middle pillar 14 of the frame member 16 forming a part of the opening 12 is installed at both ends of the inner side surface 10c of the water blocking plate 10, the water blocking plate is installed. A strip-shaped first water blocking member 18 extending in the vertical direction, which can come into contact with the first surface 14a facing the ten, is fixed. Further, a band-shaped second water stop member 22 extending in the width direction is fixed to the lower surface 10d which can come into contact with the floor surface 20 forming a part of the opening 12 when the water stop plate 10 is installed. (See FIG. 5). The first water blocking member 18 and the second water stopping member 22 are, for example, elastic members, and can be formed of soft rubber, foam rubber, elastomer, flexible resin, or the like having a large elastic deformation. The first water stop member 18 functions to elastically deform and maintain water stoppage with respect to the frame member 16 when the water stop plate 10 is installed in the opening 12. Similarly, the second water stop member 22 functions to elastically deform and maintain water stoppage with respect to the floor surface 20 when the water stop plate 10 is installed in the opening 12. The second water stop member 22 may have a rectangular cross-sectional shape common to that of the first water stop member 18, but in consideration of being deformed by the weight of the water stop plate 10 and the pressing force by the pressing mechanism described later. It may be formed thicker than the first water blocking member 18 in a state where no external force is applied.

As a mechanism for installing and fixing the water stop plate 10 in the opening 12, the water stop plate 10 includes a pressing mechanism 24, a fixing mechanism 26, and a posture maintaining mechanism 28, as shown in FIGS. 1 to 3 and 5. A positioning mechanism 30 is provided. A pair of a pressing mechanism 24, a fixing mechanism 26, a posture maintaining mechanism 28, and a positioning mechanism 30 are provided in both end regions of the water stop plate 10 in the width direction.

The pair of pressing mechanisms 24 are for determining a fixed position when the water blocking plate 10 is pressed against the floor surface 20 by changing the water blocking plate 10 from the tilted state which is the installation preparation posture to the standing state which is the installation posture. It is a mechanism. As shown in FIG. 5, the pressing mechanism 24 includes a support member 24a and a pressing member 24b. The support member 24a rotatably supports the pressing member 24b around a rotation axis arranged in the width direction. The support member 24a is attached to the inner side surface 10c which is inside when the water stop plate 10 is installed. The pressing member 24b rotatably supports the fixing mechanism 26 around a shaft portion extending in the width direction of the knob 26a. The pressing member 24b is formed in, for example, an L shape when viewed from the width direction. The pressing member 24b supports the first tip portion 24c rotatably connected to the support member 24a on one end side of the L shape and the hook 24d for hooking the hook member 28a of the posture maintaining mechanism 28 on the other end side of the L shape. A corner portion 24f in which a female screw formed on the shaft portion of the knob 26a is screwed between the second tip portion 24e and the first tip portion 24c and the second tip portion 24e is formed in the axial direction. Be prepared.

The pair of fixing mechanisms 26 consist of one facing surface 16b of the pair of frame members 16 facing each other in the width direction of the opening 12 and the first surface 14a (first water stoppage) of the center pillar 14 installed in the opening 12. The member 18 is detachably fixed to the second surface 14b or the third surface 14c orthogonal to the surface on which the member 18 is pressed. By changing the position of the fixing mechanism 26 in the width direction with respect to the water stop plate 10, the facing surface 16b facing the frame member 16 in the width direction and the second surface 14b or the third surface 14c of the center pillar 14, respectively. Contact. The fixing mechanism 26 can rotate the contact member 26b that contacts the facing surface 16b of the frame member 16 or the second surface 14b or the third surface 14c of the center pillar 14 and the contact member 26b around an axis extending in the width direction. A knob 26a for supporting the knob 26a is provided. The knob 26a includes a shaft portion on which a male screw is formed and a grip portion attached to one end side of the shaft portion. The male screw of the shaft portion is screwed into the female screw formed on the pressing member 24b, and the contact member 26b is attached to the tip of the shaft portion. When the grip portion of the knob 26a is rotated in the normal direction around the axis in the width direction, for example, the contact member 26b attached to the tip of the shaft portion moves relative to the pressing member 24b screwed into the shaft portion in the width direction. .. That is, the pair of contact members 26b are moved outward in the width direction to be brought into contact with the facing surface 16b of the frame member 16 and the second surface 14b or the third surface 14c of the center pillar 14, respectively, and the knob 26a is further screwed. The fixing mechanism 26 itself is fixed by being pressed by. As a result, the water stop plate 10 to which the fixing mechanism 26 and the pressing mechanism 24 screwed are fixed is fixed between the frame member 16 and the center pillar 14. Further, by reversing the grip portion of the knob 26a, the pair of contact members 26b are moved inward in the width direction, and the contact member 26b is moved to the facing surface 16b of the frame member 16 and the second surface 14b of the center pillar 14. Separated from the third surface 14c. That is, the water stop plate 10 can be removed from the space between the frame member 16 and the center pillar 14. As shown in FIG. 3, the contact member 26b has an L-shaped cross section so that the frame member 16 or the center pillar 14 can be contacted on two sides so as to improve the fixing stability. That is, the fixing mechanism 26 is configured to come into contact with the outer surface 16a and the facing surface 16b of the frame member 16. Similarly, the fixing mechanism 26 is configured to come into contact with the first surface 14a and the second surface 14b or the third surface 14c of the center pillar 14.

The posture maintaining mechanism 28 maintains the posture of the pressing mechanism 24. The posture maintaining mechanism 28 includes a hooking member 28a and a lock operating member 28b. The hook member 28a and the lock operation member 28b are attached to the upper region in the vertical direction on the outer surface 10a of the water stop plate 10. When the water stop plate 10 is in the standing position in the installation posture, the hook member 28a is hooked on the hook 24d fixed to the second tip portion 24e of the pressing mechanism 24, and the lock operation member 28b shifts to the locked state. By pulling it down, the lock operating member 28b is pulled with respect to the hook 24d, and the standing state of the water stop plate 10 is maintained. The posture maintenance mechanism 28 can have the same or similar structure as a clasp called a so-called draw latch or snap lock. By shifting the lock operation member 28b of the posture maintaining mechanism 28 to the released position, the engagement between the hook member 28a and the hook 24d can be released, and the water stop plate 10 is shifted to the tilted state which is the installation preparation posture. be able to. In this case, since the water stop plate 10 is supported by the pressing mechanism 24, the inclined state can be maintained. When storing or transporting the water stop plate 10, the fixing mechanism 26 can be temporarily fixed to the water stop plate 10 by hooking the hook member 28a on the hook 24d, and during storage or transportation. It can eliminate instability during transportation and prevent damage due to contact.

As shown in FIGS. 3 and 4, the positioning mechanism 30 is provided at both ends of, for example, a lower region in the vertical direction of the inner side surface 10c of the water stop plate 10 (only one of FIGS. 3 and 4 is shown). The positioning mechanism 30 is composed of a main body portion 30a, a shaft portion 30b, a pedestal 30c, and an adjusting member 30d. Then, when the water stop plate 10 is arranged in the opening 12, the main body portion 30a is configured to abut on the facing surface 16b of the frame member 16, the second surface 14b or the third surface 14c of the middle pillar 14, respectively. Has been done. The amount of protrusion of the main body 30a to the outside in the width direction can be adjusted so as to enable positioning of the water stop plate 10 in the width direction. The main body portion 30a is, for example, a disk-shaped component that can come into contact with the facing surface 16b of the frame member 16 (the second surface 14b or the third surface 14c of the center pillar 14). The main body 30a is made of, for example, hard rubber having a small elastic deformation. The shaft portion 30b has a rod shape, and a male screw is formed on the outer peripheral surface. One side of both ends of the shaft portion 30b in the width direction is inserted into an insertion hole of a pedestal 30c made of, for example, angle steel, and the main body portion 30a is fixed to the other end. The shaft portion 30b can be positioned and fixed to the pedestal 30c by an adjusting member 30d (for example, a nut) provided on the side opposite to the main body portion 30a with the pedestal 30c interposed therebetween. By adjusting the position of the shaft portion 30b with respect to the pedestal 30c, that is, the position of the main body portion 30a, the main body portion 30a can be moved in the width direction with respect to the water stop plate 10 and in the width direction with respect to the water stop plate 10. Hold the position in. By changing the position of the main body portion 30a with respect to the pedestal 30c in the width direction, the positioning mechanism 30 opens the first water blocking member 18 with the outer surface 16a of the frame member 16 or the first surface 14a of the middle pillar 14. It is possible to ensure that the portions 12 face each other in the inward and outward directions. As a result, when the water stop plate 10 is installed in the opening 12 in an upright state, the first water stop member 18 is surely elastically deformed by the outer surface 16a and the first surface 14a to ensure water stoppage. be able to.

The procedure for installing the water stop plate 10 configured in this way in the opening 12 will be described. First, the water stop plate 10 is temporarily placed on the outside (outdoor side) of the opening 12. That is, the outer surface 16a of the frame member 16 and the first surface 14a of the middle pillar 14 are leaned against each other so that both ends of the water stop plate 10 are in contact with each other. At this time, the position of the main body 30a of the positioning mechanism 30 provided at both ends of the water stop plate 10 is adjusted in advance in the width direction. As a result, when the main body portion 30a comes into contact with the facing surface 16b of the frame member 16 and the second surface 14b or the third surface 14c of the center pillar 14, and the water stop plate 10 is installed in an upright state, the first The water stop member 18 is positioned so as to abut the appropriate positions of the frame member 16 and the center pillar 14. Subsequently, with the lock operation member 28b of the posture maintaining mechanism 28 in the released position, the contact member 26b of the fixing mechanism 26 is fixed to the frame member 16 and the center pillar 14. In this case, the posture of the water stop plate 10 is such that the lower end of the water stop plate 10 to which the second water stop member 22 is fixed is the lower end of the outer surface 16a of the frame member 16 and the first surface 14a of the middle pillar 14. The upper end of the water stop plate 10 is brought into contact with the lower end, and the upper end of the water stop plate 10 is tilted outward by the amount of play of the hook member 28a loosened by releasing the lock operation member 28b (installation preparation posture). Finally, the lock operation member 28b of the posture maintenance mechanism 28 is moved to the lock position while raising the posture of the water stop plate 10 from the inclined state to the standing state (installation posture). As a result, the first water stop members 18 provided at both ends in the width direction of the water stop plate 10 press against the outer surface 16a of the frame member 16 and the second surface 14b (third surface 14c) of the middle pillar 14. It is elastically deformed and water stoppage can be ensured. Further, since the position of the water stop plate 10 is fixed in the vertical direction by the fixing mechanism 26, the water stop plate 10 is pushed down obliquely toward the opening 12 in the process of shifting to the upright state. As a result, the second water blocking member 22 provided on the lower surface of the water stopping plate 10 is pressed against the floor surface 20 and elastically deformed to ensure water stopping. When removing the water stop plate 10 from the opening 12, the reverse procedure may be performed. When the water stop plate 10 is installed in the opening 12, for example, an identification mark Q is provided on the outer surface 10a so that the outer surface 10a and the inner surface 10c can be easily distinguished, as shown in FIG. You may. The identification mark Q may be a sticker or a printed one. Further, it may be expressed by using the unevenness of the surface of the outer surface 10a. Further, the identification mark Q may indicate an installation method and a storage method in addition to the front and back guidance of the water stop plate 10.

Subsequently, the details of the center pillar 14 will be described with reference to FIGS. 3 and 4. The center pillar 14 is a component that can be connected to the end region of the inner side surface 10c of the water stop plate 10 arranged adjacently, and can be attached to and detached from the floor surface 20. The middle pillar 14 includes a pillar main body 32, a leg member 34, a hook member 36 that functions as a support, a handle 38, and the like. The column body 32 is, for example, a cylindrical component of a prism, and can be made of a lightweight and high-strength metal material such as aluminum, aluminum alloy, or stainless steel. A plurality of leg members 34 that function as one of the posture maintaining members for maintaining the posture of the center pillar 14 are provided on one end side (lower end side in FIG. 4) of the pillar body portion 32. In the case of the present embodiment, as shown in FIG. 3, the leg member 34 is a leg member that protrudes from the pillar body 32 toward the outside of the opening 12 when, for example, the middle pillar 14 is installed on the floor surface 20. 34a and leg members 34b and 34c protruding from the column main body 32 in the width direction of the opening 12 are provided. As will be described later, of the three leg members 34, the leg member 34a is configured to be removable when the middle pillar 14 is stored. The leg member 34a can be fixed to the column main body 32 by using, for example, a fastening member that can be turned by hand (for example, a knurled screw 34d or a thumbscrew). For example, an adjuster pad 34e is provided on each leg member 34. The adjuster pad 34e is used when the water blocking member 40 (elastic member such as rubber, elastomer, flexible resin, etc.) for ensuring water stopping is elastically deformed when the center pillar 14 is installed on the floor surface 20. The height is adjusted so that the standing posture of the pillar 14 can be stabilized.

The center pillar 14 can be fixed by screwing an anchor bolt 42, which functions as one of the posture maintaining members, into the floor surface 20 through, for example, a fixing through hole 34f provided in the leg member 34. By adjusting the screwing amount of the anchor bolt 42 and the protruding amount of the adjuster pad 34e, the water blocking member 40 is elastically deformed to an appropriate state, and the water blocking property equivalent to that of the water blocking plate 10 can be secured even in the middle pillar 14. The center pillar 14 has a holding structure for holding the anchor bolt 42 (posture maintenance member) removed from the center pillar 14 (leg member 34) when the center pillar 14 is removed from the floor surface 20. As an example of the holding mechanism, in the case of FIG. 4, a holding screw hole 44a for screwing and holding the removed anchor bolt 42 is provided. By fixing the anchor bolt 42 when not in use to a part of the middle pillar 14 (pillar main body portion 32) in this way, loss or damage can be easily prevented. As another example of the holding mechanism, a holding pocket (for example, a recess with a lid) may be provided in the pillar main body 32 for storage. Further, as described above, when the middle pillar 14 is stored, the leg member 34a is removed from the position (position in FIG. 4) when the leg member 34a is used upright. In this case as well, the leg member 34a is fixed to the holding screw hole 44b by using the knurled screw 34d so as not to be lost or damaged. As will be described later, the posture maintaining member such as the anchor bolt 42, the leg member 34a, and the knurled screw 34d is a water stop plate when the center pillar 14 is supported (hooked) by the water stop plate 10 by the hook member 36. It is fixed to a second surface 14b different from the first surface 14a of the center pillar 14 in contact with 10. As a result, when the center pillar 14 is supported by the water stop plate 10 by using the hook member 36, it is possible to easily support the center pillar 14 by avoiding interference between the members.

At least one of the water stop plate 10 or the center pillar 14 of the present embodiment includes a support portion that is supported by a part of the water stop plate 10 when the center pillar 14 is removed from the floor surface 20. As an example of the support portion, as shown in FIG. 4, a hook member 36 that is hooked on the upper surface 10e (see FIG. 1) of the water stop plate 10 is provided in a part of the pillar main body portion 32. As shown in FIG. 6, the hook member 36 includes, for example, a hook portion main body 36a formed by bending a plate-shaped metal such as stainless steel, and a rotary arm portion 36b connected to the hook portion main body 36a. The inner wall spacing L of the hook portion main body 36a is slightly larger than the thickness L0 (see FIGS. 3 and 5) of the water stop plate 10 in the inner and outer directions so that the hook member 36 can be easily hooked on the water stop plate 10. Is set to. The rotary arm portion 36b is rotatably fixed to the rotary shaft hole 36d of the base plate 36c fixed to one surface (for example, the third surface 14c) of the pillar main body portion 32 of the central pillar 14 by, for example, a fixing pin 36e. .. Further, in the base plate 36c, a first positioning hole 36f is formed at a position deviated from the rotation shaft hole 36d by a distance P in the longitudinal direction. Further, the second positioning hole 36g is formed at a position deviated from the rotation shaft hole 36d by a distance P in the lateral direction. That is, the first positioning hole 36f and the second positioning hole 36g are formed at positions displaced by 90 °. On the other hand, the rotary arm portion 36b is provided with, for example, an index plunger 36h that can be inserted and removed from the first positioning hole 36f and the second positioning hole 36g. When the index plunger 36h is not operated by a spring member or the like, the protruding posture inserted into the first positioning hole 36f or the second positioning hole 36g is maintained, and the position of the rotating arm portion 36b is fixed with respect to the base plate 36c. .. On the other hand, when the user pulls up the index plunger 36h against the urging force of the spring member, the index plunger 36h is pulled out from the first positioning hole 36f or the second positioning hole 36g, and the rotating arm portion 36b pulls the fixing pin 36e. It becomes rotatable in the center. That is, the fixed position of the rotating arm portion 36b with respect to the base plate 36c can be shifted by 90 °.

As described above, the hook member 36 has a first posture different from the first posture due to the moving mechanism (positioning mechanism) composed of the first positioning hole 36f, the second positioning hole 36g, and the index plunger 36h. Move between the two postures. In this case, the first posture is, for example, a support posture in which the center pillar 14 is held by the water stop plate 10, and the hook portion main body 36a protrudes in the lateral direction of the center pillar 14 from the upper surface 10e of the water stop plate 10. It is a posture that can be hooked. Further, the second posture is, for example, a posture in which the center pillar 14 is installed on the floor surface 20 and shifts when the water is stopped to support the water stop plate 10, and the side surface of the center pillar 14 (for example, the third surface 14c). It is a posture that is stored so as to overlap with. As described above, by using the index plunger 36h, it becomes easy to move the hook member 36 and maintain the posture at the moving position. Further, by fitting the index plunger 36h into the first positioning hole 36f or the second positioning hole 36g, the user can easily confirm that the hook member 36 is in an appropriate moving position (moving posture). This makes it possible and contributes to the prevention of operation mistakes. Further, when the hook member 36 shifts to the second posture, the hook member 36 overlaps with the side surface of the center pillar 14 (for example, the third surface 14c), so that it is less likely to get in the way when the center pillar 14 is used. The point of hooking and supporting the center pillar 14 on the water stop plate 10 by using the hook member 36 will be described in detail in the description with reference to FIGS. 9 to 12 described later.

The index plunger 36h used as a part of the moving mechanism is an example, and if the hook member 36 can move between the first posture and the second posture and the posture can be maintained after the movement, the other It may be configured. For example, a concave-convex portion may be provided at a corresponding position between the rotary arm portion 36b and the base plate 36c, and the posture may be maintained and the completion of movement may be confirmed by engaging the concave portion and the convex portion. Further, by providing a stopper on the base plate 36c that regulates the position of the first posture and the position of the second posture and restricting the rotational movement of the rotary arm portion 36b, it is possible to confirm the completion of the movement. You may. Further, when a stopper is used, for example, if a lock mechanism using a hook or the like is provided, the first posture and the second posture can be easily maintained.

The handle 38 is used when installing or transporting the center pillar 14. For example, the side handle 38a provided on the side surface (for example, the third surface 14c) of the pillar main body 32 is used to transport the middle pillar 14 or to use the hook member 36 to attach the middle pillar 14 to the water stop plate 10. Used when attaching and detaching. Further, the upper handle 38b provided on the upper surface 14d of the pillar body 32 is used when the middle pillar 14 is installed on the floor surface 20 in an upright state or when it is transported.

An example of the stand member 46 (storage tool) used when storing the water stop plate 10 and the center pillar 14 configured as described above will be described with reference to FIGS. 7 and 8. FIG. 7 is a front view showing an example of the stand member 46. Further, FIG. 8 is a top view showing an example of a support structure of the water stop plate 10 by the stand member 46. 7 and 8 show an example in which the stand member 46 is fixed to a wall surface 48 of a storage place (for example, a warehouse) by using a fastening member such as an anchor bolt 50. The pair of stand members 46 have an interval corresponding to the length in the width direction of the water stop plate 10 so as to maintain the standing posture of the water stop plate 10 along the wall surface 48, for example, when the water stop plate 10 is not used. It is fixed to the wall surface 48 in an open state. The pair of stand members 46 have a symmetrical shape in the width direction.

The stand member 46 is, for example, a square tubular part extending in the vertical direction, and as shown in FIGS. 7 and 8, the main body 46a, the upper opening 46b, the lower opening 46c, and the side opening 46d. , The contact plates 46e and 46f, the stepped portion 46g, and the space portion 46h are provided. The main body 46a can be formed, for example, by bending a metal plate material, for example. The upper opening 46b is an opening in which the upper side of the main body 46a is opened in the vertical direction, and both ends of the water stop plate 10 in the width direction can be received. The lower opening 46c is an opening in which the lower side of the main body 46a is opened in the vertical direction. The side opening 46d is an opening in which the opposite surface side of the pair of left and right stand members 46 facing each other in the width direction is opened in the width direction of the main body 46a, and receives both ends of the water stop plate 10.

The contact plates 46e and 46f support the water stop plate 10 from the thickness direction (inside and outside directions) when the stand member 46 receives (stores) the water stop plate 10. The abutting plates 46e and 46f are provided to face the side openings 46d in the thickness direction, and can face or contact both side surfaces (outer surface 10a, inner surface 10c) in the thickness direction of the water blocking plate 10, respectively. .. The contact plate 46e is formed by bending one end of the main body 46a in the width direction along the width direction and faces the outer surface 10a of the water stop plate 10 in the thickness direction. Further, the contact plate 46f is formed by bending the other end portion of the main body 46a in the width direction along the width direction and faces the inner side surface 10c of the water stop plate 10. That is, the abutting plate 46e and the abutting plate 46f are formed parallel to each other in the width direction and have a distance wider than the thickness L0 of the water blocking plate 10 in the thickness direction. The contact plates 46e and 46f are provided with cushioning materials 46i such as rubber or resin at the portions that come into contact with the outer surface 10a and the inner surface 10c of the water stop plate 10, and the outer surface 10a and the outer surface 10a of the water stop plate 10 and Prevents the inner surface 10c from being damaged. The contact plate 46e supports the outer surface 10a of the water stop plate 10, and the contact plate 46f supports the inner side surface 10c of the water stop plate 10. As a result, the water stop plate 10 is supported by the stand member 46 in a state of being upright in the vertical direction.

When the water stop plate 10 is inserted into the stand member 46 from the vertical direction, the contact plate 46f contacts the outside so that the positioning mechanism 30 of the water stop plate 10 does not come into contact with the inner contact plate 46f. It is provided inside the plate 46e in the width direction. Further, in order to prevent the positioning mechanism 30 from coming into contact with the inner wall of the main body 46a, a space portion 46h for accommodating the positioning mechanism 30 is provided in the main body 46a. Since the first water stop member 18 is located on the outer side in the width direction and on the inner side surface 10c in the thickness direction of the water stop plate 10 with respect to the positioning mechanism 30, the first water stop member 18 is a contact plate. It does not come into contact with 46f, and is housed in the space 46h and does not come into contact with the inner wall of the main body 46a. That is, when the water stop plate 10 is stored, the first water stop member 18 is prevented from coming into contact with a part of the stand member 46 so that deformation, deterioration, breakage, etc. are unlikely to occur.

The step portion 46g is provided in the lower opening 46c of the stand member 46 so as to support the water stop plate 10 from the lower side in the vertical direction. The step portion 46g extends along the width direction to the lower end portion of the inner wall of the contact plate 46e. That is, the stepped portion 46g projects in the thickness direction from the inner wall of the contact plate 46e. On the lower surface 10d of the water stop plate 10, a band-shaped second water stop member 22 extending in the width direction is fixed in a region substantially half in the thickness direction. The step portion 46g supports the water stop plate 10 from below by engaging with the mounting portion 10f (see FIG. 5) in which the second water stop member 22 does not exist. When the water stop plate 10 is stored by the stand member 46 by supporting the water stop plate 10 by the step portion 46g using the mounting portion 10f in which the second water stop member 22 does not exist, the second water stop member 22 The non-contact state is maintained so that the second water blocking member 22 is less likely to be deformed, deteriorated, or damaged. Further, in the case of the present embodiment, as shown in FIG. 7, since the stand member 46 is fixed to the wall surface 48 in a state of being floated upward by a predetermined distance from the floor surface 52, the second water blocking member 22 is The second water blocking member 22 is less likely to be deformed, deteriorated, or damaged at this point without coming into contact with the floor surface 52 during storage. The stand member 46 can also be fixed so that the lower opening 46c is in contact with the floor surface 52. In this case, by setting the height (thickness) of the stepped portion 46g in the vertical direction to such an extent that the second water blocking member 22 is sufficiently separated from the floor surface 52, the second water stopping member 22 is deformed as described above. It is possible to suppress deterioration, damage, etc. in the same manner.

The stand member 46 is fixed to the wall surface 48, and when the water stop plate 10 when not in use is leaned against the wall surface 48, the stand member 46 is stopped by the hook member 36 between the wall surface 48 and the water stop plate 10. It is configured to form a gap M having at least a width for interposing (storing) the middle pillar 14 supported by the water plate 10. That is, as shown in FIG. 9, the gap M is formed wider than the width N of the third surface 14c on which the hook member 36 is formed in the pillar body 32 of the middle pillar 14. If the gap M is made too wide with respect to the width N, the stand member 46 becomes large in the thickness direction, and the water stop plate 10 is too far from the wall surface 48 when the water stop plate 10 is stored, resulting in a storage space. Will increase. Therefore, in consideration of the ease of attaching and detaching the middle pillar 14 to the water blocking plate 10, it is desirable that the gap M be widened by about several cm to 5 cm with respect to the width N.

Subsequently, with reference to FIGS. 4 and 9, preparations for storage when the middle pillar 14 when not in use is hooked on the water stop plate 10 by using the hook member 36 will be described. When the center pillar 14 is hooked on the water stop plate 10 and stored, a part of the posture maintaining member used when the center pillar 14 is installed on the floor surface 20 is removed from the center pillar 14 and in order to avoid loss or damage. , Support it in a position that does not interfere with other parts during storage. For example, the anchor bolt 42 for fixing the leg member 34 to the floor surface 20 is attached to the holding screw hole 44a formed on the second surface 14b of the column main body 32 (see FIG. 4). Further, the leg member 34a is the same as the storage position defined by the holding screw hole 44b formed on the second surface 14b of the column main body 32 from the normal position (position shown in FIG. 4) by removing the knurled screw 34d. It is fixed using a knurled screw 34d (see FIG. 10). In this case, the posture maintaining members such as the anchor bolt 42, the leg member 34a, and the knurled screw 34d come into contact with the water stop plate 10 when the center pillar 14 is supported (hooked) by the water stop plate 10. It is fixed to a second surface 14b different from the first surface 14a of the above (see FIGS. 3 and 4).

Subsequently, the hook member 36 (hook portion main body 36a) is shifted from the second posture S (shown by the broken line in FIG. 9) to the first posture R (shown by the solid line in FIG. 9). That is, when the hook portion main body 36a is installed on the floor surface 20 by using the moving mechanism composed of the index plunger 36h or the like, the hook portion main body 36a is stored so as to overlap the third surface 14c of the center pillar 14. The second posture S is shifted to the first posture R which is projected from the second posture S in the lateral direction (first surface 14a side) of the middle pillar 14 and can be hooked on the upper surface 10e of the water stop plate 10.

10 to 12 are views for explaining a state in which the middle pillar 14 when not in use is hooked on the water stop plate 10 and stored by using the hook member 36. 10 is a front view of the water stop plate 10 as viewed from the outer surface 10a side, showing an example of a state in which the middle pillar 14 is hooked on the water stop plate 10 by the hook member 36. FIG. 11 is a front view of FIG. It is the CC arrow view in FIG. 12, and FIG. 12 is the DD arrow view in FIG.

When storing the water stop plate 10, the water stop plate 10 is transported to a storage place where the stand member 46 is installed, and both ends of the water stop plate 10 are inserted into the space portion 46h as shown in FIGS. 10 and 11. To do. In this case, the positioning mechanism 30 can be accommodated in the space 46h by inserting the outer surface 10a of the water stop plate 10 toward the side opposite to the wall surface 48. Further, similarly to the positioning mechanism 30, the pressing mechanism 24 and the fixing mechanism 26 protruding toward the inner side surface 10c side of the water blocking plate 10 also face the wall surface 48 side, so that when the water blocking plate 10 is stored, the passage is obstructed. It is possible to prevent damage to the pressing mechanism 24 and the fixing mechanism 26 due to contact or the like. In addition, in order to maintain the supporting posture of the water stop plate 10 inserted into the stand member 46, the water stop plate 10 may be fixed to the wall surface 48 by using a belt or the like.

As shown in FIG. 9, the hook member 36 (hook portion main body 36a) is moved to the first posture R on the upper surface 10e of the water stop plate 10 supported by the stand member 46. The pillar 14 is hooked as shown in FIGS. 10 to 12. In this case, the hook portion main body 36a is hooked at a position where it does not interfere with the handle 10b of the water stop plate 10. In this case, the first surface 14a of the center pillar 14 faces the inner side surface 10c of the water stop plate 10, but as shown in FIGS. 10 to 12, it is fixed to the second surface 14b of the center pillar 14. Since the leg member 34b and the leg member 34c fixed to the third surface 14c are parallel to the inner side surface 10c, they do not interfere with each other when the middle pillar 14 is hooked. Further, as shown in FIGS. 10 and 12, the leg member 34a, the knurled screw 34d, and the anchor bolt 42 used for fixing each leg member 34 removed from the first surface 14a of the center pillar 14 are the center pillar. Since it is fixed to the second surface 14b of the 14 (the same surface as the fixed surface of the leg member 34b), it does not interfere when the middle pillar 14 is hooked on the water stop plate 10.

As described above, according to the water stop device of the present embodiment, the gap M between the water stop plate 10 and the wall surface 48 formed when the water stop plate 10 is stored and stored by the stand member 46 is used. The center pillar 14 can be stored and stored together with the water stop plate 10. As a result, the storage space can be easily reduced. Further, since the water stop plate 10 and the center pillar 14 can be stored together, the work efficiency can be improved even when the water stop plate 10 is installed in the opening 12. It is also possible to carry the water stop plate 10 and the center pillar 14 together.

When the center pillar 14 is used, two water stop plates 10 are required for one center pillar 14. The stand member 46 shown in FIG. 7 has a structure of supporting one water stop plate 10, but for example, it may have a two-stage structure in which two water stop plates 10 are supported in the vertical direction. In this case, since the vertical direction is used as the storage space for the water stop plate 10, an increase in space can be suppressed in the width direction. In this case, it is better to hook the center pillar 14 on the water stop plate 10 on the lower stage side for better workability. If the storage space has a margin in the width direction, the stand members 46 may be arranged in the width direction. In this case, since the water stop plate 10 does not move in the vertical direction, the work of transporting the water stop plate 10 becomes easier as compared with the case where the water stop plate 10 is stored in the vertical direction.

Further, in the above-described embodiment, a water stop device of a type in which the water stop plate 10 is fixed to the outer surface 16a of the frame member 16 constituting the opening 12 by using a pressing mechanism 24, a fixing mechanism 26, or the like is shown. The fixed structure of the water stop plate 10 is not limited to this. For example, a guide member having a substantially C-shaped guide groove that opens inward in the width direction of the opening 12 and extends in the vertical direction is arranged on the outside of the opening 12, and the end portion of the water stop plate 10 is placed in the guide groove. A water stop plate 10 of a type that is inserted and supported may be used. In this case, the center pillar 14 is provided with a similar substantially C-shaped guide groove facing the opening of the substantially C-shaped guide groove of the guide member. For example, it becomes a substantially H-shaped central pillar 14 having an opening in the width direction. In this case as well, the storage of the center pillar 14 can be performed in the same manner as when the hook member 36 of the present embodiment is used, and the same effect can be obtained.

Further, in the present embodiment, as shown in FIG. 12, a type fixed to the wall surface 48 as the stand member 46 is shown, but the present invention is not limited to this, and for example, a type fixed to the floor surface 52 may be used. Further, a hook-shaped support arm may be projected from the wall surface 48 to hook the handle 10b or the like of the water stop plate 10. In this case as well, the center pillar 14 can be hooked on the water stop plate 10 by using the hook member 36 and stored, and the same effect can be obtained.

In the above-described embodiment, an example is shown in which a support portion is provided as a hook member 36 on the side of the center pillar 14 in order to hook the center pillar 14 on the water stop plate 10, but the center pillar 14 is provided on the water stop plate 10. Other structures may be used as long as they can be hooked and can be accommodated in the gap M when the water stop plate 10 is stored by the stand member 46. The support portion may be formed on the water stop plate 10 side. As an example, a hook portion protruding from the inner side surface 10c of the water stop plate 10 is provided. On the other hand, an opening or a recess into which the hook portion of the water stop plate 10 can be inserted is provided on the first surface 14a of the center pillar 14. Then, by hooking the concave portion on the hook portion, the central pillar 14 can be stored and stored by utilizing the gap M during storage of the water stop plate 10 as in the above-described embodiment. The hook portion provided on the inner side surface 10c of the water stop plate 10 may be accommodated inside the water stop plate 10 so as to be rotatable in the thickness direction of the water stop plate 10, for example. In this case, when the water stop plate 10 is installed in the opening 12, the hook portion does not protrude from the inner side surface 10c, so that the user may interfere with other structures at the time of installation or pass over the water stop plate 10. It is prevented from interfering with.

Further, in the present embodiment, an example in which the hook member 36 is hooked on the upper surface 10e of the water stop plate 10 is shown, but the present invention is not limited to this, and for example, the hook member 36 is formed in a recess formed in the inner side surface 10c of the water stop plate 10. It may be a structure for hooking, and the same effect can be obtained.

Further, in the present embodiment, an example is shown in which the opening 12 is stopped by using two water blocking plates 10 and one middle pillar 14, but the number of water blocking plates 10 arranged is the opening 12. It can be appropriately changed according to the width of the water stop plate 10, and may be 3 or more, and the number of the center pillars 14 increases according to the number of water stop plates 10 installed. In this case, since the center pillar 14 can be hooked and stored on the increased water stop plate 10, the same effect as that of the present embodiment can be obtained.

The water stop device (water stop plate, center pillar, stand member) according to the above-described embodiment and modification of the present invention is not limited to the above-mentioned embodiment and modification, but is within the scope of the claims. Various changes are possible. The water stop device according to the present embodiment may be configured by appropriately combining the components of each embodiment described above.
