Description

[Technical field]

[0001] The present invention relates to the technical field of water blocking board devices that are installed at openings such as entrances and exits of buildings such as buildings and houses. [Background technology]

[0002] Conventionally, waterproof board devices have been known that use waterproof boards to waterproof (stop water from entering) openings such as entrances and other openings in order to prevent water outside the opening from entering the interior (interior of a building, room) of a building, house, parking lot, etc. through the opening during overflow, which can occur during emergency weather such as heavy rain or typhoons. Incidentally, when installing a water-resistant board device in a location where the opening is wide from side to side, in order to reduce the water pressure that the water-resistant board receives, a configuration has been proposed in which the water-resistant board is divided into adjacent left and right sides, the adjacent edge portions of the left and right water-resistant boards are supported by a center pillar, and the center pillar is reinforced by a reinforcing rod arranged at an angle between the center pillar and the installation surface side (see Patent Document 1). In this configuration, during normal times when there is no overflow, the water-resistant board is stored in a storage space formed in a recessed shape in the installation surface, and in an emergency when there is a risk of overflow, the water-resistant board is set upright to provide waterproofing.

[0003] [Patent Document 1] JP 2016-145504 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the above-mentioned conventional system is designed to store the waterproof board device in a storage space recessed into the installation surface, which means that it is necessary to provide a storage space on the installation surface and to carry out extensive construction work such as assembling the necessary components such as the waterproof board, center pillar, reinforcing rod, etc. into the storage space so that they can swing freely. Therefore, instead of such a large-scale structure, a simplified structure may be used in which the necessary parts such as the waterproof board, center pillar, and reinforcing rod are stored in a storage place such as a shed or warehouse during normal times when there is no risk of flooding, and then taken out and assembled and installed in the opening in an emergency when there is a risk of flooding. In this case, the lower end of the reinforcing rod is detachably attached to the installation surface side, but it is expected that there may be cases where it is difficult to perform such work quickly in an emergency when there is a risk of flooding, and this is the problem that the present invention aims to solve. [Means for solving the problem]

[0005] The present invention was created in consideration of the above-mentioned actual situation and with the aim of solving these problems.The invention of claim 1 is a waterproof board device comprising waterproof boards installed adjacent to each other on the left and right to waterproof an opening such as an entrance or exit, a center pillar installed to support the adjacent side edge portions of the left and right waterproof boards, and a reinforcing rod arranged at an angle between the center pillar and the installation surface to reinforce the center pillar, wherein the waterproof board device is characterized in that it comprises a support means for supporting the lower end of the reinforcing rod in a freely engageable and disengageable manner on the installation surface side, a connecting member having guide receiver pieces at both front and rear end edges and supporting the lower end of the reinforcing rod between the front and rear of the guide receiver piece via a support shaft extending laterally in the left and right direction so that it can swing freely in the vertical direction, and a support member that is attached to the installation surface and guides the guide receiver piece so that it can slide freely in the left and right direction to position the connecting member at the installation position, and has support groove portions formed on the front and rear for engaging and supporting the guide receiver piece at the installation position. The invention of claim 2 is a waterproof board device as described in claim 1, characterized in that a cover body for covering the support groove portion during normal times when the waterproof board, center column, and reinforcing rod are removed is journaled on the support member so as to be freely opened and closed between an open position that opens the support groove portion and a closed position that closes it. Effect of the Invention

[0006] By adopting the invention of claim 1, the work of supporting the lower end of the reinforcing rod on the installation surface can be performed by simply sliding the connecting member attached to the lower end of the reinforcing rod in the left-right direction relative to the support member attached to the installation surface so that the guide receiving piece of the connecting member engages with the support groove of the support member, improving workability and making it possible to easily and quickly support the reinforcing rod on the installation surface in an emergency when there is a risk of overflow. By adopting the invention as defined in claim 2, it is possible to avoid problems such as soil and sand getting into the support groove during normal times when the waterproof board, center pillar, and reinforcing rod are removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a water-repellent board device to be installed at an opening E of an entrance, gate, or the like, and the water-repellent board device 1 is configured with support posts 2 disposed on the left and right of the opening E, a center post 3 disposed in the middle between the left and right support posts 2, and a water-repellent board 4 whose left and right edge portions are supported by the support posts 2 and the center post 3. Incidentally, in implementing this invention, the present embodiment will be described as having a single center pillar 3 and dividing the waterproof board 4 into two parts, left and right, but it is also possible to have two or more center pillars 3 divided into three or more parts to correspond to the left and right width of the opening E, and although the waterproof board 4 is illustrated as having two boards stacked one on top of the other, it goes without saying that the present invention can be implemented with a single board or three or more boards stacked together. In the following description, for the sake of convenience, the waterproof boards 4 stacked one above the other will not be distinguished from each other and will be described as being integrated (as a single board).

[0009] The support column 2 has a concave guide groove 2a formed on the inside in the left-right direction, and the outer edge portion in the left-right direction of the support column 2 is fixed via a screw 2b to a base material 5 fixed via an anchor bolt 5a to a structural member K such as a wall or gate. The outer edge portion 4a on the outer side in the left-right direction of the waterproof board 4 is configured to be loosely fitted inside the guide groove 2a. In addition, a lower frame material 6 having a guide groove 6a opening upward is embedded in the installation surface (floor surface, ground) F on which the waterproof board device 1 is installed, and the lower edge portion 4b of the waterproof board 4 is configured to fit loosely into the guide groove 6a.

[0010] The center pillar 3 is disposed so as to face the indoor side of both adjacent side edge parts 4c facing each other on the left and right with a gap between them on the left and right side of the waterproof boards 4, and is formed into a T-shape in a plan view by having a support pillar part 3a facing the left and right adjacent side edge parts 4c with a gap in the front-rear direction and a reinforcing pillar part 3b extending from the left-right center part of the support pillar part 3a to the indoor side. Furthermore, a base plate 3c facing outward in the left-right direction and indoor direction is extended from the lower end edge part of the center pillar 3, and the base plate 3c is detachably attached via bolts (fasteners) 3d to a support base material 6b extending from the indoor side end part of the lower frame material 6 along the installation surface F, so that the center pillar 3 is attached and fixed upright to the installation surface F. In this embodiment, an outdoor side member 3e is attached to the support column portion 3a of the center column 3, passing through the gap between the left and right adjacent side edge portions 4c to reach the outdoor side of the waterproof board 4 and receiving a clamp 7, which will be described later.

[0011] In this manner, the waterproof board 4 is set with its outer edge portion 4a on the left-right side loosely fitted into the guide groove 2a of the support column 2, its lower edge portion 4b loosely fitted into the guide groove 6a of the lower frame material 6, and its adjacent side edge portion 4c facing the support column portion 3a of the center column 3. When the clamp 7 provided on the outdoor side of the waterproof board 4 is tightened, the waterproof material 4d having rubber-like elasticity provided on the waterproof board 4 comes into elastic contact with the indoor side groove sides of the guide grooves 2a, 6a and the support column portion 3a of the center column 3, thereby preventing water from entering over the waterproof board 4 from the outdoor side. In addition, a cushioning material 4e is provided on the lower edge of the waterproof board 4, which supports the weight of the waterproof material 4 and elastically abuts against the bottom surface of the guide groove 6a of the lower frame material 6.

[0012] On the other hand, 8 is a reinforcing rod for reinforcing the erected center column 3, and the reinforcing rod 8 is composed of a long, cylindrical main body 8a, nut portions (female screw portions) 8b provided at both the upper and lower ends of the main body 8a, and upper and lower members 8c, 8d which are screwed into the upper and lower nut portions 8b so as to allow adjustment in the longitudinal direction. The upper end of the upper member 8c is supported by a bracket 9 which is detachably attached via a bolt 9a to the indoor side surface at the middle in the vertical direction of the center column reinforcing column portion 3b, via a horizontal support shaft 9b so as to be freely swingable in the vertical direction.

[0013] In contrast, the lower member 8d is journalled to the connecting member 10 via a support shaft 10a which also faces laterally in the left-right direction so as to be freely swingable in the up-down (front-back) direction. The connecting member 10 is shaped like a square plate, and guide receiver pieces 10b which are stepped and thin at the tip end are formed at both front and rear edge portions. A bracket 10e is attached to the thick portion 10c between the front and rear guide receiver pieces 10b via a screw 10d, and the lower end portion of the lower member 8d is journalled to the bracket 10e via the support shaft 10a so as to be freely swingable in the up-down direction.

[0014] On the other hand, a support member 11 for attaching and supporting the connecting member 10 in a freely detachable manner is attached to the indoor installation surface F via screws 11a. The support member 11 is divided into two parts, front and rear, and support groove portions 11b are formed on the opposing end edges in which front and rear guide receiving pieces 10b formed on the connecting member 10 engage freely to slide freely in the left and right direction. Then, with the connecting member 10 positioned on either the left or right side of the support member 11, the guide receiving piece portion 10b engages with the support groove portion 11b and slides left and right, thereby guiding the connecting member 10 to the mounting position, and at the mounting position the connecting member 10 is supported by the support member 11 as the guide receiving piece portion 10b engages with the support groove portion 11b. The connecting member 10 and the supporting member 11 constitute the supporting means of the present invention. In this embodiment, the reinforcing rod 8 and the connecting member 10 are assembled to the center post 3 before the center post 3 is fixed to the supporting base material 6b on the installation surface F side, and in this state the connecting member 10 is slid left and right to be supported by the supporting member 11, and then the length of the reinforcing rod 8 is adjusted as necessary before the center post 3 is fixed to the installation surface F side. By fixing the center post 3 to the installation surface F side, the left and right sliding movement of the connecting member 10 relative to the supporting member 11 is also restricted. In addition, in the event of an emergency such as overflow, the water outside the opening E acts as a force pressing the waterproof board 4 toward the interior (front-to-back direction), and further acts as a force pressing the connecting member 10 toward the interior via the reinforcing rod 8, so there is no risk of the connecting member 10 moving in the left-right direction relative to the support member 11 due to the force of the water outside the opening E.

[0015] Furthermore, the support member 11 of this embodiment is provided in a bulging shape with respect to the installation surface F, and in normal conditions when the connecting member 10 is not attached, the front and rear support grooves 11b are recessed and exposed. To avoid this, the cover 12 is pivotally supported at the front end of the support member 11 via a support shaft 12a so as to be freely swingable in the front and rear directions. The cover 12 is configured to swing from a closed position that covers the support member 11 to an open position in which it swings forward (toward the center column 3), and in the open position, the reinforcing rod 8 is arranged in an inclined position above, so that it is possible to prevent a person from accidentally stepping on the cover 12. The cover 12 is omitted in Figures 2, 3, 6, and 7.

[0016] In the embodiment of the present invention configured as described above, the waterproof board device 1 comprises waterproof boards 4 installed adjacent to each other on the left and right to waterproof an opening E such as an entrance or exit, a center post 3 installed to support the adjacent side edge portions of the left and right waterproof boards 4, and a reinforcing rod 8 disposed at an angle between the center post 3 and the installation surface F to reinforce the center post 3. Furthermore, this device is provided with a support means for supporting the lower end of the reinforcing rod 8 on the installation surface F side in a freely detachable manner, and the support means is It is constructed using a connecting member 10 which has guide receiving piece portions 10b at both front and rear end edges and which supports the lower end of the reinforcing rod 8 between the front and rear of the guide receiving piece portion 10b via a horizontal support shaft 10a extending left and right so that it can swing freely in the vertical direction, and a support member 11 which is attached to the installation surface F and guides the guide receiving piece portion 10b so that it can slide freely left and right to position the connecting member 10 at the installation position, and has support groove portions 11b formed in the front and rear which engage and support the guide receiving piece portion 10b at the installation position.

[0017] As a result, in order to support the lower end of the reinforcing rod 8 for reinforcing the center column 3 on the installation surface F, the connecting member 10 attached to the reinforcing rod 8 can be supported on the installation surface F simply by sliding it left and right relative to the support member 11 attached to the installation surface F so that the guide receiving piece portion 10b of the connecting member 10 engages with the support groove portion 11b of the support member 11.This eliminates the need for troublesome work such as tightening and fixing the lower end of the reinforcing rod to the installation surface with a bolt, and means that the support work for the reinforcing rod 8 can be performed easily and quickly even in an emergency when there is a risk of flooding, which contributes to improving the efficiency of installation work for the waterproof board device 1 in an emergency.

[0018] Furthermore, the support member 11 is provided with a lid 12 for covering the support groove 11b in normal times when the waterproof board 4, center post 3, and reinforcing rod 8 are removed. The lid 12 is pivotally supported on the support member 11 so as to be freely opened and closed between an open position that opens the support groove 11b and a closed position that closes the support groove 11b, thereby preventing problems such as soil and sand getting into the support groove 11b in normal times. Furthermore, in this embodiment, the lid 12 is attached to the front edge of the support member 11 via a support shaft 12a so as to be freely swingable in the front-rear direction, and is configured to swing toward the center post 3 to take the open position that opens the support groove 11b. As a result, in the open position, the lid 12 is positioned so as to be hidden below the inclined reinforcing rod 8, preventing people from accidentally stepping on the lid 12.

[0019] Of course, the present invention is not limited to the above-mentioned embodiment, and although the above-mentioned embodiment is a specification in which the reinforcing rod is attached to the indoor side, the present invention can be implemented even if the reinforcing rod is attached to the outdoor side. Also, in the above-mentioned embodiment, a lower frame material that supports the lower end of the waterproof board is embedded, but the present invention can also be implemented in a configuration in which a waterproof board with a waterproof material (water-stopping material) attached to its lower end is placed directly on the installation surface without providing such a lower frame material.

[0020] Next, another example of the support means for supporting the lower end of the reinforcing rod so as to be freely engaged and disengaged on the installation surface F side will be described with reference to Fig. 9. The reinforcing rod 13 of this example, like the reinforcing rod 8 of the embodiment described above, is configured with a long cylindrical main body 13a, nut parts (female thread parts) 13b provided at both the upper and lower ends of the main body 13a, and an upper member (not shown) and a lower member 13d that are screwed into the upper and lower nut parts 13b so as to allow adjustment in the length direction, and although not shown, the upper end of the upper member is supported by a bracket attached to the center column via a support shaft so as to be freely swingable in the vertical direction, similar to the embodiment described above. On the other hand, the lower member 13d of the reinforcing rod 13 of the other example has a rod shape extending linearly, and a locking portion 13f having an arc-shaped (semi-arc-shaped) locking surface 13e is formed at its lower end. Also, the upper end of the lower member 13d is screwed into a nut portion 13b provided at the lower end of the main body portion 13a, so that the protruding length of the lower member 13d protruding downward from the lower end of the main body portion 13a can be adjusted. 9, 14 is a support member attached to the installation surface F, and the support member 14 is configured with a box-shaped support box 14b that has an opening 14a on the upper side and is embedded in the installation surface F with the four peripheral edges of the opening 14a being flush with the installation surface F, and a round bar-shaped locking receiving portion 14c that is fixed at both ends to the left and right side surfaces of the support box 14b and faces the left and right directions. The dimensions are set so that the arc-shaped locking surface 13e formed at the lower end of the reinforcing rod member 13d can be externally fitted and locked onto the round bar-shaped locking receiving portion 14c so as to be slidable in the left and right directions and around the axis. The lower end of the reinforcing rod 13 is supported on the installation surface F by adjusting the downward protruding length of the lower member 13d and engaging the engaging surface 13e of the lower end of the lower member 13d with the engaging receiving portion 14c of the support member 14. Therefore, in this other example as well, the support work for the reinforcing rod 13 can be performed easily and quickly in an emergency when there is a risk of flooding. Although not shown, other examples also have a lid that can be opened and closed to cover the upper opening 14a of the support member 14 during normal operation when the waterproof board, center pillar, and reinforcing rod 13 are removed.
