As mentioned above, when multiple waterstops are connected and used, it can be used in the protruding corner-shaped opening by making an angle at the center pillar, but the position where the waterstop is installed and the building Depending on the layout of the wall surface, the positional relationship with the objects in the vicinity, etc., the waterstop may be placed in a corner shape (the two waterstops are arranged so that the water receiving surfaces (walls) face inward). May need to be placed. When the waterstop is arranged in the inside corner in this way, even if the middle pillar is used, the ends of the adjacent waterstops interfere with each other, or the fixed part of the middle pillar with respect to the floor surface and the waterstop interfere with each other. In some cases, it became difficult or impossible to install the waterstop.

The present invention has been made in view of the above circumstances, and is for connecting waterstop plates so that when a plurality of waterstop plates are connected and installed, the waterstop plates can be installed in both the outside corner state and the inside corner state. One of the purposes is to provide a central pillar.

In order to achieve the above object, the waterstop connecting middle pillar according to the present embodiment is arranged, for example, at a connecting position in the width direction of a plurality of waterstops surrounding the inundation prevention area, and the width of the waterstop is wide. It can be connected to the side edge in the direction. The waterstop connecting middle pillar extends in the width direction of one of the plurality of waterstops, and the side end side portion is connected to the end portion in the width direction. A plurality of the above stops extending in a direction substantially orthogonal to the first pillar portion provided with one connection surface and the first pillar portion on the opposite side of the first connection surface in the width direction. A second pillar portion having a second connecting surface to which the side end portion of the other waterstop of the waterstop is connected is provided. According to this configuration, for example, in the middle pillar for connecting the waterstop plate, the side end side portion of each waterstop plate is the first due to the first pillar portion and the second pillar portion extending in the direction substantially orthogonal to each other. It can be separated according to the extending length of one pillar and the second pillar. As a result, it becomes easy to prevent the ends of the adjacent waterstops from interfering with each other, and the installation becomes easy.

Further, the middle pillar for connecting the water stop plate according to the present embodiment includes a support plate for supporting the bottom surface of the first pillar portion and the bottom surface of the second pillar portion, and the support plate is, for example, the above. A bent portion in which a pillar support portion corresponding to the shape of the bottom surface of the first pillar portion and the bottom surface of the second pillar portion, and the first pillar portion and the second pillar portion are connected in a substantially orthogonal state. It is provided with a first pillar fixing portion connected to the pillar support portion at an inner position of the above, and a second pillar fixing portion connected to the pillar support portion at a position outside the bent portion. According to this configuration, for example, the pressing force generated by the water pressure received by the waterstop fixed to the first pillar side at the time of flooding and the second pillar side existing in a substantially orthogonal relationship with the waterstop. The resultant force of the pressing force generated by the water pressure received by the waterstop plate fixed to the waterstop acts on the center column for connecting the waterstop plate. At this time, since the first fixing part and the second fixing part exist inside and outside the bent part of the waterstop connecting middle pillar, the resultant force acting on the waterstop connecting middle pillar at the time of flooding should be firmly received. Can be done. That is, the support plate can firmly support the first pillar portion and the second pillar portion. By supporting the bottom surface of the first pillar portion and the bottom surface of the second pillar portion with the support plate, it becomes easy to prevent the support plate and the water stop plate from interfering with each other, and the installation becomes easy.

Further, the support plate of the waterstop connecting middle pillar according to the present embodiment includes a waterstop member having elasticity between the support plate and the floor on which the waterstop connecting middle pillar is installed. According to this configuration, water can be stopped in the same manner as the waterstop at the installation position of the waterstop connecting middle pillar.

Further, the first pillar fixing portion and the second pillar fixing portion of the waterstop connecting middle pillar according to the present embodiment each include, for example, a fastening member mounting portion, and the first pillar fixing portion. And the fastening member mounting portion of the second pillar fixing portion are formed at positions symmetrical with respect to the pillar support portion. According to this configuration, for example, even when the waterstop plate connecting middle pillar arranges the waterstop plate in the protruding corner state and the inside corner state, the first pillar fixing portion and the second pillar fixing portion Can also receive water pressure acting towards the inundation prevention area. As a result, the waterstop connecting middle pillar can be stably and firmly supported regardless of whether the waterstop connecting middle pillar is used in the protruding corner state or the inside corner state.

Further, at least one of the first pillar fixing portion and the second pillar fixing portion of the waterstop connecting middle pillar according to the present embodiment is provided with, for example, an index indicating the arrangement posture at the installation position. There is. The index may be, for example, a character or mark indicating "outer corner" or "inner corner", or may be a character or mark indicating the direction of the inundation prevention area. According to this configuration, for example, even if the waterstop connecting center pillar is a shared part that can be used in both the inside corner and the outside corner, the installation when installing the waterstop connecting center pillar. It makes it easier for the user to grasp the posture (installation direction) appropriately and easily.

According to the above configuration, when a plurality of waterstop plates are connected and installed, it is possible to provide a waterstop connecting center pillar that can be installed in both the outside corner state and the inside corner state.

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 center pillar for connecting the waterstops of the present embodiment is installed by supporting a plurality of waterstops (at least two) in the outside corner state or the inside corner state, for example, in the vicinity of the wall surface of the building or in the construction. At the opening of an object, the inundation prevention area where inundation should be avoided can be surrounded by a plurality of waterstop plates. The waterstop is a plate-shaped member that separates the inside and the outside with the waterstop as a boundary and prevents or reduces rainwater or the like from entering the inside of the waterstop.

For example, when a waterstop is installed so as to close an opening that communicates between the inside and the outside of a structure, the width direction of one of the waterstops is along the width direction of the opening on the outside of the opening. One end of the is fixed to the wall surface or the like, and the other end is fixed to the center pillar. Further, one end of the other waterstop in the width direction is fixed to the middle pillar, and the other end is fixed to the wall surface or the like. Another example is when a waterstop is installed so as to surround an object placed along a wall surface of a building, for example, a device, a structure, or a model that is easily damaged when flooded. One end of the waterstop in the width direction is fixed to the wall surface, etc., the other end is fixed to the middle pillar, one end of the other waterstop plate in the width direction is fixed to the middle pillar, and the other end is fixed to the wall surface, etc. do.

Further, when a plurality of waterstop plates are connected and arranged by using the waterstop connecting middle pillar of the present embodiment, the installation angle of the waterstop is changed at the middle pillar portion. For example, the other waterstop can be arranged in a direction substantially orthogonal to one of the waterstops. In this case, depending on the position where the waterstop is installed, the layout of the wall surface of the building, the positional relationship with the objects existing in the vicinity, etc., the waterstop may be placed in the inside corner state or in the outside corner state. It is possible. As a result, it is possible to appropriately block the opening and enclose the inundation prevention area with a plurality of waterstop plates.

When one end of the waterstop is fixed to a wall surface or the like, the wall surface may have irregularities or a right-angled portion for mounting a pressing member for fixing the waterstop may not exist. In such a case, the waterstop can be installed by mounting an auxiliary member (a member similar to the center pillar) on a wall surface or the like and forming a right-angled portion to which the pressing member is mounted.

In FIG. 1, for example, two waterstop plates 100 (100a, 100b) are arranged in an “outer corner state” using the waterstop plate connecting middle pillar 10 of the present embodiment, and the building is substantially orthogonal to each other. It is an exemplary and schematic diagram which surrounds, for example, a power distribution facility M1 installed in a recess formed by the wall surface W (W1, W2). In FIG. 1, the region surrounded by the wall surfaces W1 and W2 and the waterstop plates 100a and 100b is an inundation prevention region E1 in which it is desired to avoid the intrusion of rainwater at the time of inundation.

In FIG. 1 and subsequent views, the width direction (longitudinal direction) of the substantially rectangular parallelepiped panel-shaped waterstop plate 100a is the X direction, the width direction (longitudinal direction) of the waterstop plate 100b is the Y direction, the waterstop plate 100a and The height direction (short direction) of the waterstop plate 100b will be described as the Z direction. In this case, as described above, one end of the plate-shaped waterstop plate 100a having a flat surface portion along the X direction in the drawing is fixed to the corner portion of the wall surface W1, and the other end of the waterstop plate 100a is waterstop. It is fixed to a part of the plate connecting middle pillar 10 (the first pillar portion described later). Similarly, one end of the plate-shaped waterstop plate 100b having a flat surface portion along the Y direction in the drawing is fixed to the corner portion of the wall surface W2, and the other end of the waterstop plate 100b is a middle pillar for connecting the waterstop plate. It is fixed to a part of 10 (the second pillar portion described later). By arranging each water stop plate 100 outside the inundation prevention region E1, the water stop plate 100 is pressed by the water pressure S at the time of inundation. As a result, the waterstop plate 100 is in close contact with the wall surface forming the inundation prevention region E1 and the waterstop plate connecting middle pillar 10, and the water stoppage performance can be further improved by utilizing the water pressure at the time of inundation. The building includes, for example, a house, a building, a garage, a factory, a warehouse, a store, etc., a single wall, an object having a wall surface, and the like.

FIG. 2 is an example showing a connection mode between the waterstop plate connecting middle pillar 10 and each waterstop plate 100 when the waterstop plates 100 (waterstop plate 100a and waterstop plate 100b) are arranged in a protruding corner shape. It is a schematic partial detailed view. Further, FIG. 3 is an exemplary and schematic partial side view showing a connection mode between the waterstop plate connecting middle pillar 10 and the waterstop plate 100 shown in FIG. 2. The details of the waterstop connecting middle pillar 10 will be described later.

First, the configuration of the waterstop 100 will be described. The waterstop 100a is composed of, for example, a waterstop main body 100p, a holding mechanism 102, a waterstop seal 104, a waterstop seal 106 (see FIG. 3), a transport handle 108 (see FIG. 3), and the like.

As described above, the waterstop body 100p is configured in the form of a substantially rectangular parallelepiped panel that is long in the width direction (for example, in the case of the waterstop 100a, for example, in the X direction in the figure, and in the case of the waterstop 100b, in the Y direction). There is. The width of the waterstop main body 100p is set to be larger than the width of the opening so that the opening (general entrance / exit or the like) of the building can be closed by one sheet, for example. For example, even when water pressure is applied to the panel surface (pressure receiving surface) by itself at about 1 m to several m, the amount of deflection in the pressure receiving direction (front and back directions of the panel surface) is within a predetermined allowable range (water stop seals 104, 106). The length is set so that the strength can be secured within the range where the water blocking function can be maintained. Further, the height (length in the Z direction) of the waterstop main body 100p is a predetermined height from the floor surface forming a part of the opening or the inundation prevention region, for example, a predetermined height from the estimated inundation height. It is set at a height with a margin. In the case of the waterstop 100 installed at an opening such as an entrance / exit, the height may be set so that the user can enter / exit while straddling (for example, about 40 cm to 60 cm). The waterstop 100 is not limited to the panel, and may be, for example, a waterstop sheet having water impermeability and flexibility.

It is desirable that the waterstop plate 100 (waterstop plate main body 100p) has a weight that can be carried around, and has rigidity that can withstand the water pressure at the time of flooding. The waterstop 100 can be formed of, for example, aluminum, stale, stainless steel, polycarbonate, reinforced plastic (FRP), carbon fiber, or the like. Further, the waterstop main body 100p is formed, for example, by processing a lightweight metal plate containing aluminum and having rust resistance into an aggregate having a U-shaped cross section to form a quadrangular frame in which four aggregates are combined. Have. The openings on the front and back of the frame are square panels made of metal or resin such as aluminum or stainless steel, each of which is closed to form a waterstop body 100p. Further, by filling the internal space surrounded by the frame and the panel with the filler, the waterstop main body 100p can be made lightweight and highly rigid.

The waterstop plate 100 includes a holding mechanism 102 as a mechanism for installing and fixing the waterstop plate 100 on a wall surface or a center pillar 10 for connecting the waterstop plate. The holding mechanism 102 is provided one by one in both end regions of the waterstop plate 100 in the width direction.

The holding mechanism 102 is a mechanism for fixing the waterstop main body 100p to the corners of the waterstop connecting middle pillar 10 and the corners of the wall surface W in an upright position in the installation posture. As shown in FIG. 2, the holding mechanism 102 is connected to, for example, a substantially L-shaped pressing member 102a in a top view, which can engage with the corner portion of the waterstop connecting middle pillar 10, and the pressing member 102a. It is composed of a knob 102b that moves (presses) the pressing member 102a to the outside in the width direction of the waterstop main body 100p, for example, to operate a screw portion. The screw portion to which the pressing member 102a is connected fixes the waterstop plate 100 by advancing outward in the width direction from the main body portion of the holding mechanism 102 fixed to the waterstop plate main body 100p. Similarly, the pressing member 102a of the holding mechanism 102 provided on the other side of the waterstop main body 100p is brought into contact with the wall surface W which is the other mounting surface, and the knob 102b is operated to move the pressing member 102a to the outside in the width direction ( Advance to the wall side). As a result, the pair of holding mechanisms 102 stretches between the waterstop connecting middle pillar 10 and the wall surface, and the waterstop 100 can be fixed. On the contrary, by operating the knob 102b in the opposite direction and retracting the screw member inward in the width direction, the waterstop plate 100 can be released from being fixed. The holding mechanism 102 is a well-known mechanism, and may be another mechanism as long as it is a mechanism for fixing the waterstop plate 100 in the same manner.

Water stop seals are placed at both ends of the water stop plate body 100p in the width direction (X direction in the case of the water stop plate 100a, Y direction in the case of the water stop plate 100b) on the surface of the inundation prevention region E1 (indoor side, etc.). 104 (see FIG. 2) is provided. The waterstop seal 104 has a predetermined width in the width direction of the waterstop plate main body 100p, and is configured in the shape of a strip extending in the Z direction. The waterstop seal 104 is provided between the waterstop plate main body 100p and the waterstop plate connecting middle pillar 10 and the wall surface W in a state where the waterstop plate 100 is attached to the waterstop plate connecting middle pillar 10 and the wall surface W. Intervene.

The waterstop seal 104 is sandwiched between the waterstop plate main body 100p and the waterstop plate connecting middle pillar 10 or the wall surface W, so that the waterstop plate main body 100p is in the thickness direction (Y direction in the case of the waterstop plate 100a). , In the case of the waterstop 100b, it is elastically compressed in the X direction) to generate surface pressure. This surface pressure suppresses the ingress of water into the inundation prevention region E1 side between the waterstop plate main body 100p and the waterstop plate connecting middle pillar 10 or between the waterstop plate main body 100p and the wall surface W. .. The waterproof seal 104 is made of a material having flexibility, flexibility, and elasticity, such as rubber, an elastomer, and a flexible resin.

Further, a water stop seal 106 (see FIG. 3) is provided at the lower end of the water stop plate main body 100p. The waterstop seal 106 has a predetermined width in the thickness direction of the waterstop main body 100p (Y direction in the case of the waterstop plate 100a, X direction in the case of the waterstop plate 100b), and is a strip extending in the width direction. It is configured in a plate shape. The waterstop seal 106 is interposed between the waterstop plate main body 100p and the floor surface G in a state where the waterstop plate 100 is attached to the waterstop plate connecting middle pillar 10 or the wall surface W, and in this state, the floor. It is interposed between the surface G and 100P2.

The water stop seal 106 is sandwiched between the floor surface G and the water stop plate main body 100p, and is elastically compressed in the Z direction to generate surface pressure. This surface pressure suppresses the ingress of water into the inundation prevention region E1 from between the floor surface G and the waterstop main body 100p. The waterproof seal 106 may be made of, for example, the same material as the waterproof seal 104, or may be made of another material.

Next, with reference to FIGS. 4 and 5, a case where the waterstop plate 100 (waterstop plate 100a and waterstop plate 100b) is arranged in the inside corner state by using the waterstop plate connecting middle pillar 10 will be described.

FIG. 4 is an example showing a case where, for example, two waterstop plates 100 (waterstop plates 100a, 100b) are arranged in the “inside corner state” by using the waterstop plate connecting middle pillar 10 of the present embodiment. And it is a schematic diagram. Further, FIG. 5 is an exemplary and schematic diagram showing a connection mode between the waterstop plate connecting middle pillar 10 and each waterstop plate 100 when the waterstop plate 100 shown in FIG. 4 is arranged in the “inside corner state”. It is a partial detailed view. As shown in FIG. 4, when there is a region recessed in a substantially L o'clock shape due to the wall surface W (W3, W4, W5, W6) of the building, and for example, power distribution equipment M2 and M3 are present in the recessed region. It is necessary to prevent rainwater and the like from infiltrating the area. Therefore, in FIG. 4, the region surrounded by the wall surfaces W3, W4, W5, W6 and the waterstop plates 100a, 100b is the inundation prevention region E2. In this case, one end of the plate-shaped waterstop plate 100a having a flat surface portion along the arrow X direction in the figure is fixed to the corner portion of the wall surface W3, and the other end of the waterstop plate 100a is being connected to the waterstop plate. It is fixed to a part of the pillar 10 (the first pillar portion described later). Similarly, one end of the plate-shaped waterstop plate 100b provided with a flat surface portion along the arrow Y direction in the drawing is fixed to the corner portion of the wall surface W6, and the other end of the waterstop plate 100b is being connected to the waterstop plate. It is fixed to a part of the pillar 10 (the second pillar portion described later). By arranging each waterstop 100 outside the inundation prevention region E2, each waterstop 100 is pressed by the water pressure S at the time of inundation. As a result, the waterstop plate 100 is in close contact with the wall surface forming the inundation prevention region E2 and the waterstop plate connecting middle pillar 10, and the water stoppage performance can be improved by utilizing the water pressure at the time of inundation.

When the waterstop 100 is arranged in the inside corner state, as shown in FIG. 5, the orientation of the substantially L-shaped bent portion of the waterstop connecting middle pillar 10 with respect to the inundation prevention region E2 is shown in FIG. Unlike the case, only the mounting position of the pressing member 102a of the holding mechanism 102 with respect to the waterstop plate connecting middle pillar 10 is different, and the fixing method of each waterstop plate 100 is the waterstop plate 100 in the protruding corner state described with reference to FIG. Is the same as when arranging. Therefore, a detailed description of the waterstop 100 will be omitted.

Subsequently, FIGS. 6 to 8 will be added, and the details of the waterstop connecting middle pillar 10 will be described. FIG. 6 is an exemplary and schematic perspective view showing a pillar main body portion 12 constituting the waterstop connecting middle pillar 10.

A pillar body portion 12 having a substantially L-shape in view is provided. It is desirable that the pillar body portion 12 has a weight that can be carried around, for example, and has a rigidity that can withstand the water pressure at the time of flooding. The pillar body 12 can be made of, for example, a rust-preventive metal plate containing stainless steel or aluminum. The pillar body 12 has a hollow structure in which, for example, an aggregate whose cross-sectional shape is processed into a U shape is combined to form a skeleton, and the surface thereof is covered with a metal plate such as stainless steel or aluminum in order to reduce the weight. May be good. Further, the rigidity may be improved by filling the internal space of the skeleton with a filler or the like.

As shown in FIGS. 2 and 6, the pillar main body portion 12 extends in the width direction (X direction in FIG. 2) of one of the plurality of waterstop plates 100, and is in the width direction. A first pillar portion 12a including a first connection surface 12ac to which a side end portion of the waterstop plate 100a (for example, a pressing member 102a of the holding mechanism 102) is connected is provided at the end portion. Further, the pillar body portion 12 extends in a direction substantially orthogonal to the first pillar portion 12a on the opposite side of the first connection surface 12ac, and the other waterstop plate of the plurality of waterstop plates 100 is provided. A second pillar portion 12b including a second connecting surface 12bc to which a side end portion of the 100b (for example, a pressing member 102a of the holding mechanism 102) is connected is provided.

It is provided in a place. The anchor opening 16a and the adjuster screw portion 18a of the first pillar fixing portion 14b and the second pillar fixing portion 14c are formed at positions symmetrical with respect to the reference point R of the support plate 14. For example, as shown in FIG. 2, when the waterstop plate connecting middle pillar 10 is installed to fix the waterstop plate 100 in the protruding corner state, the waterstop is fixed to the first pillar portion 12a side. When the plate 100a is flooded, the plate 100a receives the water pressure S, and a pressing force in the Y direction is generated. Further, the water stop plate 100b fixed to the second pillar portion 12b side, which exists in a relationship substantially orthogonal to the water stop plate 100a, receives the water pressure S at the time of flooding and receives the pressing force in the X direction. As a result, the waterstop connecting middle column 10 receives the resultant force of each pressing force (force in the 45 ° direction in the XY plane). As shown in FIG. 5, the same applies to the case where the waterstop connecting middle pillar 10 is installed to fix the waterstop 100 in the inside corner state. Since the support plate 14 has the first pillar fixing portion 14b and the second pillar fixing portion 14c inside and outside the bent portion of the waterstop connecting middle pillar 10, the waterstop connecting is being connected during flooding. The resultant force acting on the pillar 10 can be firmly received. That is, the support plate can firmly support the first pillar portion and the second pillar portion. Further, the anchor openings 16a are arranged inside and outside along the direction of the resultant force (45 ° direction), and two anchor openings 16a are arranged with the anchor openings 16a interposed therebetween. Then, the anchor bolt 16 is inserted and fixed in each anchor opening 16a. As a result, the center pillar 10 for connecting the waterstop is suppressed from being lifted in the 45 ° direction by the acting resultant force regardless of whether it is used in the "outer corner state" or the "inner corner state". ..

In this way, by making the configuration of the first pillar fixing portion 14b and the configuration of the second pillar fixing portion 14c symmetrical in the support plate 14, the waterstop plate connecting middle pillar 10 is in the protruding corner state and the inside corner state. It can be a shared part that can be used in both. As a result, it can contribute to the standardization of the middle pillar 10 for connecting the waterstop. Further, it is possible to contribute to the reduction of the product cost by sharing the inside corner state and the outside corner state, the management cost of the waterstop connecting middle pillar 10, and the like.

The number of anchor openings 16a corresponds to the number of anchor bolts 16 that can secure the fixing strength when the waterstop connecting middle pillar 10 is fixed to the floor surface G, that is, the fixing strength that can withstand the maximum water pressure. It can be selected as appropriate. Similarly, the number of the adjusting screw portions 18a may be appropriately selected as long as the horizontality of the waterstop connecting middle pillar 10 can be adjusted, for example, if there are two or more. Note that FIG. 3 shows an example in which the number of anchor bolts 16 and the number of adjusters 18 are different from the number of anchor openings 16a and adjuster screw portions 18a shown in FIG. 7.

As shown in FIG. 3, a spacer member 20 made of a metal plate or the like corresponding to the shape of the bottom surface of the pillar body portion 12 is fixed to the lower surface of the pillar support portion 14a of the support plate 14 by, for example, welding. .. Further, a water stop member 22 is fixed to the lower surface of the spacer member 20 with, for example, an adhesive or double-sided tape in order to stop water at the installation position of the water stop plate connecting middle pillar 10. Like the waterproof seal 104 and the waterproof seal 106, the waterproof member 22 is made of a material having flexibility, flexibility, and elasticity, such as rubber, an elastomer, and a flexible resin. Since the water stop member 22 is provided on the bottom surface of the water stop plate connecting middle pillar 10, the same water stopping effect as the water stop plate 100 can be obtained even at the position of the water stop plate connecting middle pillar 10. As a result, even when the waterstop connecting middle pillar 10 is used, it is possible to reliably suppress the inundation of the inundation prevention region E1 and the inundation prevention region E2.

FIG. 8 is an exemplary and schematic top view showing a state in which the pillar main body portion 12 including the first pillar portion 12a and the second pillar portion 12b is connected to the support plate 14 shown in FIG. 7. As described above, since the shape of the pillar support portion 14a is formed to correspond to the shape of the bottom surface of the pillar main body portion 12, the pillar main body portion 12 is stably supported and the water pressure is increased by mounting the water stop plate 100. Even when S is involved, the waterstop plate 100 can be stably supported and water can be stopped.

As shown in FIG. 8, on the upper surface of the pillar body 12, for example, a handle 24 used for transporting the waterstop connecting middle pillar 10 to the installation position or from the installation position to the storage position. Is provided. In the case of FIG. 8, in order to facilitate the transportation of the waterstop connecting middle pillar 10, for example, handles 24 are formed at the ends of the first pillar portion 12a and the second pillar portion 12b, respectively. The number and position of the handles 24 can be changed as appropriate.

Further, it is determined whether the middle pillar 10 for connecting the waterstop of the present embodiment is used in the "outer corner state" or in the "inner corner state" depending on the situation of the place where it is installed. Therefore, at least one of the first pillar fixing portion 14b and the second pillar fixing portion 14c may be provided with an index 26 indicating the installation posture at the installation position. For example, as shown in FIG. 2, when the waterstop connecting middle pillar 10 is installed in the posture of the protruding corner, as shown in FIG. 8, it protrudes to the second pillar fixing portion 14c on the protruding corner side. "OUT" is added as an index 26 indicating a corner. Further, as shown in FIG. 5, when the waterstop connecting middle pillar 10 is installed in the inside corner posture, "IN" is used as an index 26 indicating the inside corner on the second pillar fixing portion 14c on the inside corner side. ". In another example, a mark such as an arrow may be added as an index 26 indicating the direction of the inundation prevention region E1 or the inundation prevention region E2. For example, when the waterstop connecting middle pillar 10 is used in the protruding corner state as shown in FIG. 2, the inundation prevention region E1 is on the side of the first pillar fixing portion 14b, so that the first pillar fixing portion 14b is used. An index 26 is attached. Further, when the waterstop connecting middle pillar 10 is used in the inside corner state as shown in FIG. 5, the inundation prevention region E2 is on the side of the second pillar fixing portion 14c, so that the index is used for the second pillar fixing portion 14c. Add 26. The index 26 may be a character, a number, a mark, a pattern, or the like, as long as it indicates the installation posture of the waterstop connecting middle pillar 10 at the installation position, and the same effect can be obtained. By forming the index 26 by printing, a sticker, or the like, the waterstop connecting middle pillar 10 having the same shape can be easily used as "outside corner" or "inside corner". As a result, it is possible to contribute to reduction of manufacturing cost, management cost and the like.

As described above, the waterstop connecting middle pillar 10 of the present embodiment can be used without changing the configuration in either the “inside corner state” or the “outside corner state”. As a result, the versatility of the related parts of the waterstop 100 can be improved. Further, by making the fixing mode of the first pillar fixing portion 14b of the support plate 14 by the anchor bolt 16 and the fixing mode of the second pillar fixing portion 14c by the anchor bolt 16 symmetrical with respect to the pillar supporting portion 14a. , The strength that can withstand the water pressure at the time of flooding can be the same regardless of whether it is used in the "inside corner state" or in the "outside corner state". As a result, it is possible to suppress the difference in performance depending on the usage state and contribute to the improvement of quality.

In the above-mentioned example, an example in which water is stopped by using one waterstop connecting middle pillar 10 and two waterstops 100 is shown, but depending on the shape of the inundation prevention region, for example, " The waterstop connecting middle pillar 10 arranged in the "inside corner state" and the waterstop connecting middle pillar 10 arranged in the "outside corner state" may be used in combination. As a result, it becomes possible to enclose a wider inundation prevention area or an inundation prevention area having a complicated shape with a plurality of waterstop plates 100. Even in such a case, both ends of the waterstop plate 100 are supported by the wall surface W or the center pillar 10 for connecting the waterstop plates, so that each waterstop plate 100 does not bend due to water pressure and stops water. It can be performed.
