  However, in the water stop device of Patent Document 1, the entire closing member is removed from the water stop panel as a closing member for closing the cutout portion so as to be openable. For this reason, when performing a water stop apparatus at a construction site, etc., a water stop panel and a closure member will be handled separately, respectively.

  It is an object of the present invention to provide a water stop device that can handle a water stop panel and a closing member individually as they are integrated when performing construction work or the like at a construction site. Is to provide.

  The water stop device according to the present invention includes a water stop panel that can be opened and closed with respect to at least a part of the opening provided in the non-moving body, and the water stop panel from the upper end to the lower end of the water stop panel. In the water stop device, the water stop device is formed in a cut-in state and has a notch for passing through the water stop panel by a person straddling, and a closing member for releasably closing the notch. A part is connected to the water stop panel.

  In this water stop device, since a part of the closing member is coupled to the water stop panel, there is no need to handle the water stop panel and the closing member individually at the site where the water stop device is constructed. Since it can be handled as a modified one, construction work and the like can be easily performed.

  In the present invention, the shape of the opening of the non-moving body that is at least partially opened and closed by the water stop panel is arbitrary, and according to the shape of the opening, the overall shape of the water stop panel as viewed from the front, for example, It may be a square or a trapezoid.

  Moreover, the shape of the notch part formed in the water stop panel in a cut state from the upper end to the lower end of the water stop panel and closed so as to be openable by the closing member is also U-shaped, substantially U-shaped, V-shaped. The shape may be any shape such as a substantially V shape, and the overall shape of the closing member in front view may be, for example, a quadrangle, a trapezoid, a triangle, an inverted triangle, or the like, depending on the shape of the notch.

  When the closing member has a side portion extending in at least one of the vertical direction, the left-right direction, and the oblique direction with respect to the vertical direction and the left-right direction, the closing member is closed at this side portion.

The part can be closed by the sheet member, and the notch can be opened by separating the left and right side parts of the sheet member from the water stop panel.

  In addition, in this way, one of the lower side and the upper side of the sheet member is coupled to the water stop panel, and the left and right sides of the sheet member can be separated from the water stop panel. The lower side of the sheet is the side connected to the water stop panel, and the sheet member is wound around the winding shaft so that the sheet member can be fed out. What is necessary is just to be able to move to an upper side, paying out.

  Further, in order to allow the winding shaft to move upward while the sheet member is fed out by raising the water level, for example, the winding shaft is connected to the float member via a connecting means, and the flow member is raised by raising the water level. It is only necessary to configure the take-up shaft to move upward while unwinding the sheet member.

  In order to connect the take-up shaft to the float member through the connecting means in this way, and the flow member rises as the water level rises, the take-up shaft moves upward while feeding the sheet member. The winding shaft, the float member, and the connecting means may be arranged on the surface on the side where the water pressure acts among the front and back surfaces of the water-stop panel, or the inside of the water-stop panel is a hollow portion into which water enters. In this hollow portion, the winding shaft, the float member, and the connecting means may be housed and arranged.

  According to the latter, the winding shaft, the float member, and the connecting means are disposed inside the water-stop panel, and therefore, the winding shaft, the float member, and the connecting means are protected from an unexpected external force by the water-stop panel. be able to.

  Further, in the present invention described above, in order to be able to close the opening formed in the non-moving body in a watertight state more reliably by the water-stopping panel, among these water-stopping panels and non-moving bodies. A water-tight seal member may be attached to at least one of them.

  In addition, in order to be able to more securely close the notch formed in the water stop panel with the closing member, a water-tight seal is provided on at least one of the water stop panel and the closing member. A member may be attached.

  Furthermore, the water stop device according to the present invention can be applied to any device for closing at least a part of the opening formed in the non-moving body with the water stop panel. It is an apparatus for closing at least a part of the entrance / exit on the ground leading to an underground shopping area in a watertight state, and another example is an apparatus for closing at least a part of the entrance / exit of a building in a watertight state.

  The non-moving body includes a receiving member that is provided to receive the water stop panel when the opening is closed and is immovable with respect to the water stop panel that opens and closes the opening.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated based on drawing. The water stop device according to the present embodiment is for closing a lower portion of the ground entrance / exit leading to a subway station or the like in a watertight state. FIG. 1 shows a ground structure 1 in which an entrance 2 leading to an underground facility such as a subway station or underground mall is formed, and an opening of the ground structure 1 which is an unmoving body in the present embodiment. A stairs 3 is extended from the entrance 2 to the underground facility. The ground structure 1 includes a roof portion 4, left and right side wall portions 5, and two left and right column portions 6 provided at the front end portions of these side wall portions 5. A portion surrounded by the two pillars 6 is an entrance 2.

  FIG. 2 is a side sectional view of the ground structure 1. A case 7 is attached to the lower surface of the front end of the roof portion 4, and an opening / closing moving means for moving the water stop panel 10 according to the present embodiment up and down is accommodated in the case 7. . The opening / closing moving means has a winding shaft 11, and the winding shaft 11 is rotatably supported by brackets 7 </ b> A disposed on the left and right side portions of the case 7. The winding shaft 11 is coupled to the upper ends of two left and right wires 12 that are string-like members, and these wires 12 are horizontally directed by direction changing rollers 13 disposed on the inner surfaces of the left and right side wall portions 5. The direction of the wire 12 is changed downward, and the lower ends of these wires 12 are coupled to the lower end of the water stop panel 10.

  A pair of left and right guide rails 8 in which two left and right wires 12 are movably housed are attached to the inner surfaces of the left and right side wall portions 5. Each guide roller 14 is rotatably attached, and these guide rollers 14 can be rotatably inserted into the guide rail 8 having a cross-sectional channel shape. The lower ends of the guide rails 8 are connected to the upper ends of water-stop panel receiving members 15 having a vertical length, and these water-stop panel receiving members 15 are connected to the stairs 3 side of the left and right column portions 6. It is attached to the inner surface.

  As shown in FIG. 2, when the water stop panel 10 has reached a fully closed position that closes the lower portion of the entrance 2, as shown in FIG. 3, which is a cross-sectional view taken along line S <b> 3-S <b> 3 of FIG. In addition, the left and right end portions of the water stop panel 10 and the guide rollers 14 attached to the end surfaces of these left and right end portions each have a cross-sectional channel shape opened toward the entrance / exit 2 side (in the left and right direction). The water stop panel receiving member 15 is housed inside. The receiving member 15 includes front and rear flange portions 15A and 15B, and a web portion 15C that connects outer end portions that are end portions on the side wall portion 5 side of the flange portions 15A and 15B.

  Therefore, when the winding shaft 11 rotates forward and the wire 12 is wound around the winding shaft 11, the water stop panel 10 comes out of the receiving member 15, and thereafter, the guide roller 14 is guided by the guide rail 8. As a result, the water stop panel 10 opens and moves upward. Further, when the winding shaft 11 rotates in the reverse direction and the wire 12 is fed out of the winding shaft 11, the guide roller 14 is guided by the guide rail 8, whereby the water stop panel 10 is guided by the guide rail 8. Then, the water stop panel 10 reaches the above-described fully closed position in which the left and right ends of the water stop panel 10 and the guide roller 14 are housed inside the water stop panel receiving member 15.

  The case 7 shown in FIG. 2 accommodates a drive device 35 for rotating the winding shaft 11 forward, reverse, and stopped in accordance with the operation of the operation device 19 disposed on the ground structure 1. The take-up shaft 11 performs forward rotation and the like by the drive force from the drive device 35 connected to the take-up shaft 11.

  For this reason, the water stop panel 10 at the normal time is stopped at the fully open position where the guide roller 14 is housed inside the guide rail 8 by the operation of the operation device 19, and the water stop panel 10 at this time is The entire entrance / exit 2 is open. And when there exists a possibility that water may flow into the above-mentioned underground facility from the entrance / exit 2 by heavy rain etc., the water stop panel 10 is lowered to the fully closed position by operating the operating device 19.

  4 is a cross-sectional view taken along line S4-S4 of FIG. As can be seen from FIG. 4, a water stop panel pressing member 16 is housed and fixed inside each water stop panel receiving member 15. The water stop panel pressing member 16 having a length in the vertical direction has an inclined surface 16A extending from the upper end partway in the length direction, and the inclined surface 16A extends downward and enters the inside of the entrance / exit 2, that is, The surface is inclined toward the staircase 3 described above, and the lower side of the inclined surface 16A is a vertical surface 16B that extends vertically downward continuously from the inclined surface 16A.

  For this reason, when the water stop panel 10 is closed and moved toward the fully closed position by the reverse rotation of the winding shaft 11 as described above, the right and left ends of the water stop panel 10 enter the inside of the water stop panel receiving member 15. 4, when the lower end portions of the left and right end portions of the water stop panel 10 abut against the inclined surface 16A of the water stop panel pressing member 16, the water stop panel 10 is opened and closed. When the water stop panel 10 reaches the fully closed position, as shown by the solid line in FIG. 4, the left and right ends of the water stop panel 10 Of the front and rear flange portions 15A and 15B of the water stop panel receiving member 15, the inner surface of the rear flange portion 15B serving as the flange portion on the staircase 3 side is pressed by the pressing action of 16B.

  And the sealing member 17 which has watertightness is attached to the back surface used as the surface pressed by the inner surface of the rear flange part 15B among the front and back both surfaces of the right-and-left end part of the water stop panel 10 in this way. Further, a sealing member 18 having water tightness is also attached to the lower surface of the water stop panel 10. For this reason, when the water stop panel 10 reaches the fully closed position, the seal member 17 is pressed against the inner surface of the rear flange portion 15B, and the seal member 18 is pressed against the floor (road surface) 9 of the entrance 2 by the weight of the water stop panel 10. Thus, the lower portion of the entrance 2 that is closed by the water stop panel 10 is closed in a watertight state.

  In addition, since the water stop panel receiving member 15 becomes the above-mentioned unmoving body, and is attached to the ground structure 1, this water stopping panel receiving member 15 comprises a part of unmoving body.

  As shown in FIG. 1, the water stop panel 10 is formed with a notch 30 that is opened and closed by a door 20. FIG. 5 is a front view illustrating the entire water stop panel 10 including the door 20, and FIG. 6 is a plan view illustrating the entire water stop panel 10 including the door 20. 7 is an overall front view of only the water stop panel 10 shown excluding the door 20, FIG. 8 is an overall plan view of only the water stop panel 10 shown excluding the door 20, and FIG. FIG. 3 is an overall perspective view of only the water stop panel 10 shown excluding the door 20. As can be seen from FIG. 9, the cutout portion 30 formed in the water stop panel 10 is provided in a U shape or a substantially U shape in a cut state from the upper end to the lower end of the water stop panel 10. The notch 30 can be opened and closed by the door 20. For this reason, this door 20 is a closing member for closing the notch 30 so that opening is possible.

  The water stop panel 10 includes a front surface 10A (a surface on the outer side of the entrance / exit 2) to a back surface 10B (a surface on the inner side of the entrance / exit 2 or a surface on the stairs 3 side) at the left and right ends and the lower part of the notch 30 ) Is formed in the vertical direction at the left and right ends of the notch 30, and the notch 30 has a front shape that follows the shape of the notch 30. It is formed in the left-right direction at the lower part of. Further, the amount of depression of the depression 31, in other words, the depth dimension of the water stop panel 10 in the thickness direction with respect to the depression 31 is a dimension corresponding to the thickness dimension of the door 20. Further, the overall front shape and overall front dimension of the door 20 correspond to the overall front shape and overall front dimension of the notch 30 including the recessed portion 31. The waterstop panel 10 is provided with a thin portion 32 at the left and right end portions and the lower portion of the cutout portion 30 due to the recessed portion 31.

  The outside of the entrance / exit 2 is the upstream side when water flows in, and the inside of the entrance / exit 2 is the opposite side to the upstream side, and water flows in from the upstream side. It is the side that wants to prevent or suppress the inflow of water.

  As shown in FIG. 1 and FIG. 5, among the left and right side portions of the door 20 whose front shape is a quadrangle, one side portion is formed by two upper and lower hinges 21, so that the water stop panel 10. Is bound to. Thus, the side part which becomes the side part extended in the up-down direction of the door 20 is combined with the water stop panel 10 by the hinge 21, so that the door 20 opens and closes in the left-right direction. The notch 30 is closed by the door 20 when the door 20 is closed and rotated with respect to the water stop panel 10.

  As shown in FIG. 9, seal members 22, 23, and 24 having water-tightness are attached to the water stop panel 10 at the tip end portion in the recess direction of the recess portion 31 described above. Furthermore, since the hinge 21 is, for example, a gravity hinge, when the door 20 opens the notch 30, the door 20 naturally generates a closing force by the automatic closing action of the hinge 21. Thereby, when the door 20 closes the notch 30, the door 20 is sealed to the above-described thin portion 32 formed in the water stop panel 10 by the recess 31 at the left and right ends and the lower part of the notch 30. , 23, 24 (see FIG. 6), and therefore, the thin portion 32 is a door contact portion for the door 20 to hit. Further, when the door 20 is received by the thin portion 32 in this way, the back surface of the door 20 hits the seal members 22, 23 and 24.

  As shown in FIGS. 5 and 6, the door 20 and the water stop panel 10 are provided with closing means for keeping the door 20 with the notch 30 closed in this closed state. The closing means includes a latch device 25 disposed on the door 20 and a latch receiving member 26 disposed on the water stop panel 10. FIG. 10 shows a plan sectional view of the latch device 25 and the latch receiving member 26. The latch device 25 is housed in a case 27 disposed in the door 20, a spring 28 serving as a resilient member housed in the case 27, and slidable in the left-right direction inside the case 27. A latch member 29 receiving a resilient force in a direction protruding from the spring 28 to the outside of the door 20, and the latch receiving member 26 latches when the door 20 closes the notch 30. It arrange | positions in the internal location of the water stop panel 10 facing the member 29 in the left-right direction.

  The leading end 29A of the latch member 29 on the latch receiving member 26 side is in the thickness direction of the water stopping panel 10 and the door 20 as the surfaces on both sides in the thickness direction of the water stopping panel 10 and the door 20 extend toward the latch receiving member 26 side. Further, the front end portion 26A on the latch member 29 side of the latch receiving member 26 also has a surface on both sides in the thickness direction of the water stop panel 10 and the door 20 on the latch member 29 side. As it extends, the dimensions of the water stop panel 10 and the door 20 in the thickness direction are gradually tapered.

  For this reason, when the door 20 that has opened the notch 30 rotates and closes around the hinge 21 to close the notch 30 by the automatic closing action of the hinge 21 described above, the tip of the latch receiving member 26 The latch member 29 with which the tip portion 29A comes into contact with 26A is once retracted and then advanced by the elastic force from the spring 28, whereby the tip portion 29A of the latch member 29 and the tip portion 26A of the latch receiving member 26 are moved. The door 20 which closed the notch part 30 by contacting is maintained in this closed state. Further, when the door 20 closes the notch 30 and the rear surface of the door 20 (the surface on the staircase 3 side) is pushed, the latch member 29 moves backward with respect to the latch receiving member 26, so the door 20 Opens and rotates around the hinge 21 to open the notch 30.

  As shown in FIG. 10, the door 20 in the normal state closes the notch 30 by the tip part 29 </ b> A of the latch member 29 and the tip part 26 </ b> A of the latch receiving member 26 being in contact with each other. .

  As described above, when heavy rain or the like, the lower portion of the entrance 2 is closed by the water stop panel 10 reaching the fully closed position, and the water level due to heavy rain or the like reaches the height of the notch 30. When not reached, a person who is in the underground facility such as the subway station or underground shopping area and has come to the vicinity of the entrance 2 by the stairs 3 pushes the door 20 from the back side of the door 20, thereby opening the door 20. By opening and turning, the notch 30 can be opened, whereby the person can pass through the water stop panel 10 and escape to the outside of the entrance 2 by straddling the notch 30. After that, the door 20 is automatically closed and rotated around the hinge 21 by the automatic closing force of the hinge 21 such as the above-described gravity hinge. Closed.

  Moreover, water pressure due to heavy rain acts on the surface (surface opposite to the staircase 3 side) 10A of the front and back surfaces 10A and 10B of the water stop panel 10 shown in FIG. 6, and the water level rises. When the water level reaches the height position of the door 20, the door 20 comes into pressure contact with the above-described seal members 22, 23, and 24 attached to the water stop panel 10 due to water pressure. For this reason, the notch part 30 provided in the water stop panel 10 so that a person can pass the water stop panel 10 can be closed in a more watertight state by the door 20 on which water pressure acts.

  In the present embodiment, the latch member 29 is not slid in the lateral direction by operation of an operation member such as a door knob. For this reason, the door 20 does not need to be provided with a member that protrudes to the outside, such as an operation member such as a door knob.

  Furthermore, the door 20 when the notch 30 is closed comes into contact with the above-described thin portion 32 provided as a door stop portion on the water stop panel 10, so that the door 20 on which the water pressure is applied is replaced with the water stop panel 10. In addition, the door 20 is strongly pressed against the seal members 22, 23, and 24 by this water pressure, so that the water-tightness of the door 20 to the notch 30 is reduced by the seal members 22, 23, and 24. Sealability can be improved.

  In the present embodiment described above, the door 20 serving as a closing member for closing the cutout portion 30 so as to be openable is a hinge 21 at a side portion that is a side portion extending in the vertical direction of the door 20. Therefore, the water stop panel 10 and the door 20 are not individually handled at the site where the water stop device according to the present embodiment is constructed. Since 20 can be handled as an integrated unit, construction work and the like can be easily performed.

The height position at which the lower side portion 60 </ b> A is coupled to the back surface portion 52 is a position below the above-described concave portion 52 </ b> A formed in the back surface portion 52. Further, the width dimension in the left-right direction of the sheet member 60 is larger than the width dimension in the left-right direction of the notch 70. For this reason, as shown in FIG. 14, when the take-up shaft 61 rotates and moves upward, the sheet member 60 is fed out from the take-up shaft 61, and the sheet member 60 allows the water stop panel to be moved. The recess 52A formed in the back surface portion 52 of the 50 is gradually blocked from the lower side to the upper side, whereby the notch 70 is also gradually closed from the lower side to the upper side.

  The sheet member 60 is attached with a watertight seal member 68 that is in close contact with the back surface portion 52 and has flexibility at the left and right end portions that contact the back surface portion 52 of the water stop panel 50. For this reason, when the sheet member 60 is unwound from the take-up shaft 61, the water-tight seal member 68 is in a band-like shape and is in close contact with the back surface portion 52 of the water stop panel 50, whereby the notch 70 However, the sheet member 60 is closed in a watertight state. For this reason, the left and right side portions of the sheet member 60 in which the lower side portion 60 </ b> A is coupled to the water stop panel 50 are locations that are in close contact with the back surface portion 52 of the water stop panel 50 in a watertight state.

  The watertight seal member 68 is, for example, a magnet tape. The first to third rotating members 63 to 65 are, for example, sprocket holes and pulleys, and the first and second endless traveling members 66, 67 are, for example, roller chains and belts.

  And among the surface part 51 and the back surface part 52 of the water stop panel 50, in the surface part 51 used as the surface where water pressure acts, as FIG. 11 shows, the lower part near the above-mentioned sealing member 18 is shown. , A water inlet 69 is formed.

  Since the lower end of the wire 12 whose upper end is coupled to the winding shaft 11 of FIG. 1 is connected to the water stopping panel 50, similarly to the water stopping panel 10 of the above-described embodiment, By the forward and reverse rotation, the water stop panel 50 moves up and down, and the lower portion of the entrance 2 shown in FIG. 1 and the like is closed by the water stop panel 50 that has reached the fully closed position.

  Thus, when the water stop panel 50 has reached the fully closed position and the water level due to heavy rain or the like has not reached the height position of the water inlet 90, or has reached the height position of the water inlet 90. However, when the height of the water flowing into the hollow portion inside the water stop panel 50 from the water introduction port 90 does not reach the height position of the float member 62, the above-mentioned subway station, underground mall, etc. A person who is in the underground facility and has come to the vicinity of the entrance 2 by the stairs 3 can pass through the water stop panel 50 and escape to the outside of the entrance 2 by straddling the notch 70.

  Moreover, in the surface part 51 which is the surface where the water pressure by heavy rain acts among the surface part 51 and the back surface part 52 of the water stop panel 50, a water level rises and this water level is the height position of the water inlet 90. Then, water enters the cavity inside the water stop panel 50 from the water introduction port 90. When the water level in the hollow portion further rises, the float member 62 rises due to buoyancy, which causes the second endless running member 67 to run and the first to third rotating members 63 to 65 to rotate. The endless traveling member 66 also travels.

  For this reason, the winding shaft 61 whose end is rotatably connected to the first endless traveling member 66 moves upward, and as a result, as shown in FIG. Therefore, the cutout portion 70 formed so that a person can pass through the water stop panel 50 is a side portion extending in the vertical direction of the sheet member 60 as described above. When the left and right side portions are in close contact with the back surface portion 52 of the water stop panel 50 via the seal member 68, the watertight state is closed.

  Further, when the water level at the surface portion 51 of the water stop panel 50 reaches the height position of the above-described recess 51A formed in the surface portion 51, the water passes from the recess 51A to the cavity inside the water stop panel 50. At this time, the take-up shaft 61 is raised to a position higher than the water level at this time, and the sheet member 60 closes the recess 52 </ b> A formed in the back surface portion 52 of the water stop panel 50. Therefore, water does not flow through the water stop panel 50 and flow into the stairs 3 side.

  In the present embodiment, the diameters of the large-diameter rotating member 64B of the first rotating member 63 and the second rotating member 64 around which the first endless traveling member 66 is wound are multiplied by the second endless traveling member 67. Since the diameter of the small-diameter rotating member 64A of the third rotating member 65 and the second rotating member 64 is larger than that of the float member 62, the winding shaft 61 can be moved to the upper side more than the rising amount of the float member 62. The vertical length of the notch 70 that can be closed by the member 60 can be increased.

  Further, when the water level in the hollow portion inside the water stop panel 50 is lowered, the float member 62 is lowered, so that the sheet member 60 is taken up by the take-up shaft 61 that moves downward. Opened. For this reason, the sheet member 60 is a closing member for closing the notch 70 so as to be freely opened. Further, the first to third rotating members 63 to 65 and the first and second endless running members 66 and 67 constitute a connecting means for connecting the winding shaft 61 and the float member 62.

  In this embodiment, since the lower side portion 60A of the sheet member 60 serving as a closing member is coupled to the water stop panel 50, the water stop panel 50 and Since the sheet members 60 are not handled individually and the water stop panel 10 and the sheet member 60 can be handled as an integrated unit, construction work and the like can be easily performed.

  Furthermore, the inside of the water stop panel 50 is a hollow portion into which water enters, and in this hollow portion, the sheet member 60, the winding shaft 61, the float member 62, and the above-described connecting means are accommodated. Therefore, these can be protected from external force or the like.
