The sheet type water stop device 100 is installed in the rectangular opening O in the middle of the passage P and is used to shield the rectangular opening O. In the following, one side of the passage P will be referred to as a protection region R1 and the other side of the passage P will be referred to as a flooded region R2 with the sheet type water stop device 100 interposed therebetween. The sheet-type water stop device 100 roughly includes a sheet body 10, a sheet receiving portion 20, and a pressing body 40.

In the following, the extending direction of the passage P in which the sheet type water stop device 100 is installed (the direction substantially perpendicular to the surface of the sheet body 10 extended in the passage) is the first direction D1, and the vertical direction is the second direction D2. The substantially horizontal direction along the surface of the sheet body 10 extended in the aisle is referred to as the third direction D3 (see FIGS. 4 and 5).

The sheet body 10 is scrollably pulled out from a storage box 30 arranged along any wall surface of the rectangular opening O and extended. In the present embodiment, a case where the storage box 30 is installed along the vertical surface Pu1 which is the upper wall surface of the passage P will be described as an example. For the sheet body 10, various materials having waterproofness, water pressure resistance, and flexibility can be used. The sheet body 10 is, for example, wound and housed in a storage box 30, and is used by being scrolled vertically downward from the storage box 30 and stretched.

The storage box 30 is fixed to the vertical surface Pu1 on the upper wall Pu of the passage P, which is substantially parallel to the surface of the sheet body 10 extended in the passage and faces the flooded area R2. In the example shown in FIG. 4, before the construction of the sheet-type water stop device 100, the length of the passage P is drooped over substantially the entire third direction D3 of the passage P by adding concrete or the like to the upper wall of the existing passage structure. A structure X is formed, and the storage box 30 is fixed to the vertical surface Pu1 on the flooded region R2 side of the hanging structure X.

The sheet receiving portion 20 is provided integrally with the passage structure along the four sides of the rectangular opening O of the passage P. The upper seat receiving portion 21 provided along the upper side of the rectangular opening O is fixed to the lower surface of the hanging structure X described above, and the left seat receiving portion 22 provided along the left side of the rectangular opening O is the left wall of the passage P. The right seat receiving portion 23 provided in Pl and provided along the right side of the rectangular opening O is provided on the right wall Pr of the passage P, and is provided on the floor Pd of the passage P along the lower side of the rectangular opening O. The portion 24 is provided inside a groove Y extending along the third direction D3. The upper seat receiving portion 21, the left seat receiving portion 22, the right seat receiving portion 23, and the lower seat receiving portion 24 pass along the four sides of the rectangular opening O of the passage P so that the surfaces on the flooded region R2 side are flush with each other. It is provided integrally with the structure.

The sheet receiving portion 20 other than the lower sheet receiving portion 24 is a member 60 having a substantially U-shaped cross section, in which a part close to the flooded region R2 is arranged with the opening facing the wall surface and the groove oriented in the third direction D3. It is composed of. The side wall on the protective region R1 side of the member 60 is formed on a structure fixed to the lower surface of the hanging structure X forming a part of the seat receiving portion 20, or a structure fixed on the left wall Pl or the right wall Pr. The fixed portion 61 is fixed, and the side wall of the member 60 on the water immersion region R2 side becomes the pressed portion 62 that receives the pressing force of the pressing body 40 via the sheet body 10 (see FIG. 8).

The pressed portion 62 of the member 60 has a length that does not reach the wall surface of the passage P, and a gap is formed between the side wall end portion that becomes the pressed portion 62 and the wall surface of the passage P. This gap becomes a continuous passage 70 leading from the flooded area R2 to the protected area R1 through the side of the stretched sheet body 10. A wire 81 of a window operator 80, which will be described later, for operating the movement of the pressing body 40 is inserted into the communication passage 70.

The groove of the member 60 forms a storage chamber 63 separated from the protection region R1 in a state where the sheet body 10 is pressed and brought into close contact with the pressed portion 62. The accommodation chamber 63 forms a dead end-like space that is formed on the protected area R1 side of the seat body 10 and is isolated from the protected area R1, and the inundation area R2 passes through the communication passage 70 that passes through the side of the seat body 10.

The chain case 83 has a connecting tool 84 that can move forward from the chain case 83, and the connecting tool 84 is connected to a pressing body 40 on the flooded region R2 side through a communication passage 70.

As shown in FIG. 4, the groove Y is formed by excavating the floor Pd, which is an existing passage structure, and embedding and fixing a member having a U-shaped cross section before the construction of the sheet type water stop device 100. To. In the groove Y, along with the upper seat receiving portion 21, the left seat receiving portion 22, and the right seat receiving portion 23 described above, the lower seat receiving portion 24 is embedded so that the surface on the flooded region R2 side is flush with each other. .. The groove Y is covered and shielded by a metal groove lid Y2 when the sheet type water stop device 100 is not used.

The lower seat receiving portion 24 is formed flush with the left seat receiving portion 22 and the right seat receiving portion 23 in the second direction D2 in the vertical direction (vertical direction), and is formed flush with the inner bottom of the groove Y. There is no gap. Therefore, in a state where the sheet body 10 is closely fixed to the lower sheet receiving portion 24 by the pressing body 40, water does not infiltrate from the inundation region R2 to the protection region R1 through the groove Y.

On the flooded region R2 side of the sheet receiving portion 20, a pressing body 40 that faces each side of the sheet receiving portion 20 as a whole is arranged. In the present embodiment, the pressing body 40 has a four-sided frame shape in which a portion for pressing and sandwiching the four side edges of the sheet body 10 is integrally provided, and is formed of a highly rigid metal as shown in FIG. , A ridge 48 having a shape in which the center is horizontally projected in a V shape on the sheet receiving portion 20 side is provided on the seat receiving portion 20 at a portion that is one side of the pressing body 40 and opposes each side of the sheet receiving portion 20. It is formed on the entire part that opposes each side of. The ridge 48 is also formed of a highly rigid metal plate. Further, an elastic body 24a is embedded in a portion of the lower sheet receiving portion 24 that opposes the ridge 48. With this configuration, the elastic body 24a is elastically deformed according to the shape of the ridge 48, and the sheet body 10 is pressed and sandwiched between the ridge 48 and the elastic body 24a. The sheet body 10 can be stretched with a strength corresponding to the water pressure applied to the sheet body 10. The shape of the ridge 48 may be any shape as long as the sheet body 10 can be pressed and sandwiched between the ridge 48 and the elastic body 24a of the lower sheet receiving portion 24. For example, the center is horizontally W-shaped and has corners. It may be shaped like a trapezoid or a trapezoidal shape. Further, as the material of the elastic body 24a, a material that elastically deforms rubber or resin (urethane or the like) is preferably used.

As shown in FIGS. 6 and 7, the upper side portion 41 of the pressing body 40 has a pressing surface 41a facing the upper sheet receiving portion 21, and the left side portion 42 of the pressing body 40 faces the left sheet receiving portion 22. The pressing body 40 has a surface 42a, the right side 43 of the pressing body 40 has a pressing surface 43a facing the right sheet receiving portion 23, and the lower side 44 of the pressing body 40 has a pressing surface 44a facing the lower sheet receiving portion 24. .. The pressing surfaces 41a, 42a, 43a, 44a are formed flush with each other.

The lower side portion 44 is arranged in the groove Y, and two or more door rollers 45 are arranged on the lower surface 44b of the lower side portion 44 of the pressing body 40 so as to be separated from each other along the third direction D3. The lower side portion 44 is in contact with and supported by the inner bottom Y1 of the groove Y via the door roller 45. The entire pressing body 40 can reciprocate in the groove Y along the first direction D1 by rolling the door roller 45.

In the present embodiment, the reciprocating movement of the pressing body 40 is operated by using the window operator 80. The window operator 80 has an operation unit 82, a chain case 83, and a wire 81.

The wire 81 is inserted through the wire tube 86 extending between the operation unit 82 and the chain case 83, and can move forward and backward in the wire tube 86. When a rotation operation is performed on the operation handle 82a of the operation unit 82, the wire 81 advances / retracts from the operation unit 82 by the amount of advance / retract according to the operation amount, whereby the wire 81 moves into the wire tube 86. It will move forward and backward.

As described above, the chain case 83 has a connecting tool 84 that can be freely advanced from the chain case 83, and the amount of advancement of the connecting tool 84 from the chain case 83 is variable according to the amount of advance / retreat movement of the wire 81 that penetrates the inside. Will be done. In the chain case 83, the wire 81 and the connector 84 are interlocked with each other by using, for example, a mechanical motion conversion mechanism such as a gear or a rack and pinion.

The chain case 83 is fixed in the storage chamber 63 as described above, and the tip of the connecting tool 84 is connected to the pressing body 40. Therefore, the connector 84 moves the pressing body 40 forward and backward in response to the rotation operation of the operating unit 82 with respect to the operating handle 82a, and the pressing body 40 reciprocates in the groove Y along the first direction D1.

The sheet body 10 has a length such that the left and right edges extend to the outside of the pressing body 40 in the stretched state. That is, as shown in FIG. 8, a U-shaped guide plate 12 in a plan view is vertically arranged on the left wall Pl and the right wall Pr along the second direction D2 which is the vertical direction. The guide plate 12 is for guiding the left and right edges of the seat body 10 when the seat body 10 is stretched along the pressed portion 62 of the seat receiving portion 20. In this way, by guiding the left and right edges of the seat body 10 that moves up and down by the guide plate 12, it is possible to extend the seat body 10 vertically to the front surface of the seat receiving portion 20. Then, when the sheet body 10 is in the stretched state and the pressing body 40 is moved to a position where the pressing body 40 is in close contact with the sheet receiving portion 20, the sheet body 10 is pressed and sandwiched between the sheet receiving portion 20 and the pressing body 40. ..

As shown in FIG. 4, a mullion 90 is erected on the upper wall Pu and the floor Pd of the passage P at an intermediate position (substantially central position) in the third direction D3 so as to be oriented vertically. Hereinafter, the configuration of the mullion 90 will be described with reference to FIGS. 13, 14 and 15. The mullion 90 is configured to be expandable and contractible, and is configured to expand and contract in multiple stages (4 stages in this embodiment). That is, the third stage 90c is fitted in the lowermost stage 90d in a nested manner, the second stage 90b is fitted in the third stage 90c in a nested manner, and the uppermost stage 90a is fitted in the second stage 90b. It has a structure in which it is retractably fitted in a nested manner.

When the mullion 90 is not in use, it is stored horizontally in the groove Y of the floor Pd of the passage P in the shortest contracted state (the third stage 90c, the second stage 90b, and the uppermost stage 90a are contracted). ing. The lowermost part of the mullion 90 (bottom 90d) is fixed to the bottom of the substantially central portion of the groove Y by a hinge 90e as a lower fixing portion, and the hinge 90e is horizontal, which is in an unused state. It can be displaced to the vertical state, which is the state or the state of use.

When the mullion 90 is used, the mullion 90 is vertically displaced, and the uppermost stage 90a, the second stage 90b, and the third stage 90c are each extended to the maximum. An upper fixing portion 91 is provided on the upper portion of the uppermost stage 90a. The upper fixing portion 91 includes a fixing portion main body 91a made of a latch lock, a fixing pin 91b arranged on the upper portion of the fixing portion main body 91a, a release string 91c hanging below the fixing portion main body 91a, and a mullion 90 (top stage). It is composed of a locking claw 91d projecting horizontally at the uppermost portion of 90a).

The fixing pin 91b is for fixing the vertical standing of the mullion 90 to the locking striker 92a arranged on the upper wall Pu of the passage P. The fixing pin 91b is provided so as to project above the fixing portion main body 91a by an urging force such as a spring. The fixing pin 91b is formed in a substantially right-angled triangular shape having an inclined surface, and when the upper end of the mullion 90 is moved in a direction to stand vertically and the inclined surface of the fixing pin 91b comes into contact with the locking striker 92a. , The fixing pin 91b is configured to move into the fixing portion main body 91a against the urging force of the spring or the like. Then, when the contact between the inclined surface of the fixing pin 91b and the locking striker 92a is released, the mullion 90 is in a vertically erected state, and is projected above the fixing portion main body 91a by an urging force such as a spring. The structure is such that the tilt of the mullion 90 is fixed by the locking striker 92a.

The locking claw 91d is for locking the maximum extended state of the mullion 90, and the locking claw is formed in a through hole provided in the locking material 92b arranged on the upper wall Pu of the passage P. This is to enable the maximum extension state of the mullion 90 to be maintained by inserting the 91d.

In order to change the mullion 90 having the above-described configuration from the vertical state in which it is used to the stored state, the release string 91c hanging from the lower part of the fixing portion main body 91a is pulled downward to resist the urging force such as a spring. The fixing pin 91b is housed in the fixing portion main body 91a. In this state, the mullion 90 whose standing state is vertically fixed by the locking striker 92a can be tilted, and the uppermost stage 90a, the second stage 90b, and the third stage 90c are reduced, respectively. That is, the mullion 90 is shrunk to the maximum by internally fitting the third stage 90c into the lowermost stage 90d, internally fitting the second stage 90b into the third stage 90c, and internally fitting the uppermost stage 90a into the second stage 90b. Can be stored horizontally in the groove Y of the floor Pd of the passage P.

Further, a plurality of horizontal rail-shaped reinforcing members 94 may be erected in a horizontally separated state in the immediate vicinity of the protected area R1 side of the stretched sheet body 10. For example, the cross rail-shaped reinforcing member 94 is housed in the accommodating portion 93, taken out from the accommodating portion 93 when the sheet type water stop device 100 is used, and provided on the side wall of the passage P (not shown). It is fixed to and erected across the passage P. In this way, by locating the plurality of cross rail-shaped reinforcing members 94 in the immediate vicinity of the protective area R1 side of the sheet body 10 in which the plurality of cross rail-shaped reinforcing members 94 are spread, the plurality of cross rail-shaped reinforcing members 94 can be combined with the above-mentioned mullion 90. Similarly, it functions as a reinforcing material for the sheet body 10 against the water pressure applied to the sheet body 10 from the flooded region R2 side.

Further, as shown in FIG. 16, the reinforcing member 94 is integrally sandwiched with the sheet body 10 by sandwiching the aggregate 11 made of a plurality of steel wires or the like horizontally in the vertical direction of the sheet body 10 at predetermined intervals. When the sheet body 10 is stretched or wound up by forming the reinforcing member 94, the sheet body 10 and the plurality of aggregates 11 may be integrally stretched or wound up. As a result, when the sheet body 10 is expanded, a plurality of aggregates 11 as the reinforcing material 94 can be expanded at the same time, so that it is not necessary to separately prepare the reinforcing material 94 as the reinforcing material of the sheet body 10.

Further, both end portions 11a of the plurality of aggregates 11 are formed in a spherical shape. Then, as shown in FIG. 17, a guide plate 12a formed in a substantially U shape surrounding both end portions 11a of the aggregate 11 in a plan view is vertically formed on each of the left wall Pl and the right wall Pr. It is provided vertically along the second direction D2. The guide plate 12a is for guiding both end portions 11a of a plurality of aggregates 11 of the sheet body 10 when the sheet body 10 is stretched along the pressed portion 62 of the sheet receiving portion 20. In this way, by guiding both end portions 11a of the plurality of aggregates 11 of the sheet body 10 that move up and down by the guide plate 12a, the passage P is only required to extend the sheet body 10 vertically to the front surface of the sheet receiving portion 20. A cross rail-shaped aggregate can be erected so as to cross. With this configuration, the pressing body 40 including the plurality of aggregates 11 as the reinforcing material 94 is pressed and sandwiched, and functions as a reinforcing material of the seat body 10 against the water pressure applied to the sheet body 10 from the flooded region R2 side. To do.

Further, as shown in FIG. 16, a well-known manual handle hoisting machine 13 can be used when the sheet body 10 is stretched or wound vertically downward inside the storage box 30. The handle hoisting machine 13 includes a hoisting device 13a, a shaft center fixing portion 13b, and a shaft center 13c. A hook portion 13d is provided at the lower part of the hoisting device 13a, and by hooking the tip of the handle 13e on the hook portion 13d and rotating the handle 13e in the horizontal direction, the hoisting device 13a rotates in the vertical direction in the vertical direction. The shaft center 13c, which is converted into the rotation of the hoisting device 13a and rotatably suspended in the vertical direction between the hoisting device 13a and the shaft center fixing portion 13b, rotates in the vertical direction to accommodate the seat body 10 in the housing box 30. It is easy to extend it vertically and to wind it around the axis 13c. In particular, by using the manual handle hoisting machine 13 instead of the electric type, it is possible to prevent the handle hoisting machine 13 from malfunctioning due to electric leakage at the time of flooding, and to surely expand the seat body 10 at the time of flooding. Is possible.

Therefore, in the following description, only the structure of the pressing body 444 that presses the lower edge portion of the sheet body 10 having a structure different from that of the pressing body 241 according to the second embodiment will be described. The pressing body 444 that presses the lower edge portion of the seat body 10 is provided by a piercing lever fixed to the back surface of the groove lid Y2 that covers the groove Y of the floor Pd of the passage P when the sheet type water stop device 400 is not used. It is composed. The groove lid Y2 is pivotally supported by a hinge on the edge of the opening on the flooded region R2 side of the groove lid Y, and when the end portion of the groove lid Y2 on the protected region R1 side is pulled up, the groove lid Y2 is substantially upright. The posture can be fixed and maintained.

The pressing body 444 has a structure in which two members 444a and 444b (rod-shaped or plate-shaped members) are connected via a hinge 444c. Then, in the state where the groove lid Y2 is closed, the two members 444a and 444b are held on the back surface of the groove lid Y2 in a folded state with the hinge 444c portion as the center. The member 444a is axially supported on the back surface of the groove lid Y2 at the end opposite to the connecting portion by the hinge 444c, and the member 444b extends along the groove Y to the end opposite to the connecting portion by the hinge 444c. The ridge 444d is fixed.

The hinge 444c can rotate in a folded state in one rotation direction by closing the groove lid Y2 from the state in which the two members 444a and 444b extend linearly, and in the other rotation direction. It is desirable that the structure is such that the rotation to the folded state is restricted. That is, it is desirable that the structure is such that the foldable rotation is possible when the groove lid Y2 is folded and held on the back surface, and the foldable rotation is restricted in the opposite direction. This makes it possible to maintain the piercing state described later.

The length to the tip of the ridge 444d when the two members 444a and 444b extend linearly is L1, and the distance from the shaft support portion on the back surface of the groove lid Y2 to the elastic body 221 of the seat receiving portion 220 is set. If L2, then L1> L2. As a result, when the ridge 444d at the tip of the pressing body 444 folded on the back side of the groove lid Y2 is extended toward the elastic body 221, the ridge 444c is bent in the opposite direction and before rotating. 444d is unevenly engaged with the elastic body 221.

As described above, the pressing body 444 as a part of the pressing body 440 may be configured to generate a pressing holding force toward the sheet receiving portion 220 by the foldable piercing member. That is, the edge of one side of the sheet body 10 can be a piercing type pressing body 444, and the remaining three sides can be the above-mentioned urging means type pressing bodies 441, 442, 443.
