The swinging of the water stop door 20A is restricted by this contact, and the water stop door 20A is positioned at the second position.
This also applies to the waterproof door 20B side. When the support piece 26 of the door bracket 25 is detached from the upper surface 13a of the support member 13 and is locked to the notch 132, the outer surface of the support piece 26 is removed. 26a and 26b are in contact with the inner surfaces 132a and 132b of the notch 132, and the contact restricts the swinging of the water stop door 20B so that the water stop door 20B is positioned at the second position. It has become.

  In the state where the water stop doors 20A and 20B are positioned in the second position as described above, the water stop doors 20A and 20B are based on the side supported by the support shaft 12 as shown in FIG. When it is set as the part side, the tip part side opposite to this is located in front of the position where the support shaft 12 is provided in the front-rear direction of the doorway. That is, the water blocking doors 20A and 20B are configured to protrude in a substantially square shape (mountain shape) in a plan view toward the outside of the entrance / exit while being positioned at the second position.

As shown in FIGS. 2 (b) and 2 (c), the water blocking door 20A is mainly formed by stacking a plurality of plate-like horizontally long door bodies 21 in the vertical direction, and has a height capable of water blocking the entrance / exit. It is configured. Each door body 21 is made of an aluminum alloy hollow extruded profile, and both sides in the longitudinal direction are held by a proximal-side longitudinal member 22 and a distal-side longitudinal member 23. In addition, the water stop door 20A (20B) is not restricted to what was comprised from the several door body 21, It comprised by the one door body formed with the large area (it has height). Also good.
Further, the door body 21 may be integrally configured by stacking a plurality of flat woods or synthetic resin materials in the vertical direction.

As shown in FIG. 5 (a), the base end side vertical member 22 has a substantially U-shaped cross section, and is mounted from the base end side so as to hold the base end side of each door body 21. And it is being fixed with respect to each door 21 by the rivet 21b (refer Fig.3 (a)). As shown in FIG. 3A, a substantially T-shaped door bracket 24 and a substantially L-shaped door bracket 25 are fixed to the side of the base end side vertical member 22, and among these, the door bracket 24 and 24 are fixed to the base end side vertical member 22 with bolts (not shown), and are pivotally supported on the support shaft 12 between the bracket 11a and the bracket 11b.

That is, in a state where the door bracket 25 is supported on the upper surface 13a of the support member 13, since the height h1> the height h2, the water stop door 20A has a load of the water stop door 20A on the floor surface F. Without being in contact with such a state, it is supported at a height h1 obtained by adding a floating allowance S2 to the height h2. Therefore, the water stop door 20A swings so as to float from the floor surface F in a state where the door bracket 25 is positioned on the upper surface 13a of the support member 13 (see FIGS. 6A and 6B).

  On the other hand, the water stop door 20 </ b> A is swung, and the support piece 26 of the door bracket 25 is detached from the upper surface 13 a (support region) of the support member 13 and moved downward as compared with the first position. In the state where the support piece 26 is locked to the notch 132 of the support member 13 (see FIG. 6C), h2> h3, so that the upper surface 111a of the bracket 11d and the support piece 26 of the door bracket 25 are A gap S1 is formed between the bottom surface 26d and functions as a margin for ensuring that the water blocking door 20A comes into contact with the floor surface F (see FIG. 5B). Accordingly, when the door bracket 25 is detached from the upper surface 13a of the support member 13, the water stop door 20A reliably comes into contact with the floor surface F by its own weight as shown in FIGS. 3 (b) and 5 (b). It will be.

Here, at the lower end of the water stop door 20A, as shown in FIG. 7 (c), a lower end packing for stopping the water stop door 20 on the floor surface F via an attachment member 28 having a substantially U-shaped cross section. 29 is attached. The lower end packing 29 has a hollow portion 29a inside and a lower portion bulges downward. In the present embodiment, the door bracket 25 swings on the upper surface 13a of the support member 13 as described above. Thus, the lower portion of the lower end packing 29 is set so as to contact the floor surface F to the extent that it does not become a resistance to swinging of the water stop door 20A. Such a lower end packing 29 is attached by engaging a groove 29c with an engagement piece 28a of the attachment member 28, and is a presser member 28b fixed to a hollow portion of the attachment member 28 with a screw or the like (not shown). It is fixed so that the 29b side can be pressed. Thereby, a deformation | transformation of the lower end packing 29 is suppressed suitably.
In addition, you may comprise so that a clearance gap may be formed between the lower end packing 29 and the floor surface F in the state in which the door bracket 25 rock | fluctuates the upper surface 13a of the supporting member 13. FIG.

Further, as shown in FIG. 7A, the front end side vertical member 23 has a substantially U shape in plan view, and is mounted from the front end side so as to hold the front end side of each door body 21, It is fixed to each door 21 by rivets 21b. The front-side vertical member 23 is formed by joining the front-side vertical member 23a and the rear-side vertical member 23b, which are substantially L-shaped in plan view, partially overlapping each other.
The rear longitudinal member 23b has an end 23c extending forward, and a locking hole 23d for locking the locking member 30 is formed in the end 23c.
Further, a seal member 124 formed so as to bulge toward the side is provided on a side portion of the rear longitudinal member 23b. The seal member 124 is provided over the entire vertical direction of the rear longitudinal member 23b, and the opposing seal members 124, 124 are in a state where the water stop doors 20A, 20B are deployed at the second position. It comes in close contact with water.
The sealing members 124, 124 protrude in a substantially letter shape in plan view toward the outside of the entrance / exit, so that when the water stop doors 20A, 20B are subjected to water pressure when the water increases, etc. In this state, they come into contact with each other, and the adhesion is improved.

As shown in FIG. 7B, the locking member 30 is formed, for example, by bending a single wire, and is inserted into the locking holes 23d and 23d provided in the end 23c of the rear vertical member 23b. The insertion part 31 which can be penetrated, and the folding | returning part 32 folded by the substantially U shape are provided.
As shown in FIG. 8 (a), such a locking member 30 is inserted into the locking hole 23d from the side of one end 23c, and this is further engaged with the other end 23c. It is inserted into the stop hole 23d and attached to the end portions 23c and 23c. Then, the folded-back portion 32 is rotated downward about the axis of the insertion portion 31 and is locked so as to sandwich the two end portions 23c and 23c with the folded-back portion 32 as shown in FIG. 8B. . Thereby, the front-end | tip parts of water stop door 20A, 20B will be latched so that separation is impossible.
As shown in FIG. 8 (b), the locking member 30 has a curved portion 33 between the insertion portion 31 and the folded portion 32. When the water blocking door 20A (20B) is accommodated, the locking member 30 has an end. The locking member 30 can be held on the end 23c by hooking the curved portion 33 or the folded portion 32 into the locking hole 23d of the portion 23c.
In this embodiment, the end part 23c of the above-mentioned rear side vertical member 23b is provided in two places at intervals in the up-down direction of the water stop door 20A (20B), as shown in FIG. The upper and lower portions can be locked by the locking members 30 and 30. Note that the locking position and the number of the locking members 30 can be arbitrarily set. Moreover, you may provide the edge part 23c continuously in the up-down direction of the water stop door 20A (20B). By doing in this way, the freedom degree of arrangement | positioning of the latching member 30 increases.

  As shown in FIG. 1B, the water stop device as described above is covered and accommodated by the cover 40 on the wall surfaces W1, W2 of the entrance / exit. The cover 40 is made of, for example, an aluminum alloy hollow extruded shape, and includes a front cover 41, a rear cover 42, an upper cover 43, and an opening / closing cover 44 that covers the side of the cover 40. . The front cover 41, the rear cover 42, and the upper cover 43 have substantially the same configuration. For example, the front cover 41 is fixed to the wall surface W1 using an anchor 41e as shown in FIG. 5A. A substantially U-shaped fixing member 41a, a cover member 41b attached to the fixing member 41a, an L-shaped member 41c attached to the rear surface of the cover member 41b, and attached to the rear surface of the cover member 41b regulated by the L-shaped member 41c And a door seal member 41d having a U-shaped cross section having a hollow portion.

  Here, the door seal member 41d comes into contact with the front surface of the water stop door 20A in a state where the water stop door 20A is positioned at the second position. The space between the water door 20A is sealed. The door seal member 41d has a hollow section having a substantially U-shaped cross section, and is attached so that the hollow portion communicates with a region outside the water stop door 20A partitioned by the water stop door 20A. Therefore, the water pressure that flows in when the water increases increases so that the front cover 41 and the water stop door 20A are in close contact with each other, and water can be suitably prevented from entering the water stop door 20A.

Next, a procedure for unfolding and installing (closing) the water stop doors 20A and 20B will be described.
First, as shown in FIG.1 (b), the opening / closing cover 44 of the cover 40 is opened, and the water stop door 20A is exposed.
Next, the water stop door 20A is grasped by hand, and the water stop door 20A in the first position is pulled out to the front side. Then, the door bracket 25 swings around the support shaft 12 while being supported by the upper surface 13a of the support member 13, and the water blocking door 20A is pulled out onto the floor surface F.
Here, the height h2 from the floor surface F to the bottom surface 26d of the door bracket 25 is lower than the height h1 from the floor surface F to the upper surface 13a of the support member 13 (see FIG. 5B). The water stop door 20A swings on the support member 13 by being positioned higher than the state (position) in contact with the floor surface F with a load by the floating allowance S2. Therefore, when it is pulled out, the water stop door 20A does not slide on the floor surface F with a load, and a smooth drawer can be realized.

After that, when the door bracket 25 is swung to a position where it deviates from the upper surface 13a of the support member 13 (a position that deviates from the support region), the support piece 26 of the door bracket 25 is caused to move to the upper surface of the support member 13 by its own weight. It is locked so as to be removed from 13a and dropped into the notch 132. Accordingly, the water stop door 20A is positioned at the second position, and the lower end packing 29 of the water stop door 20A comes into contact with and closely contacts the floor surface F due to the dead weight of the water stop door 20A. Will be stopped by the water stop door 20A.
In addition, in the state where the water stop door 20A is positioned at the second position, the door seal member 41d comes into close contact with the front surface of the water stop door 20A, thereby preventing water from entering.

  Then, the water stop door 20B is pulled out in the same procedure and positioned at the second position. And the front-end | tip part of water stop door 20A, 20B is latched by the latching member 30, and the seal members 124 and 124 are stuck. Thereby, as shown to Fig.2 (a), in the state by which water stop door 20A, 20B was pulled out to the 2nd position, it protruded in the substantially square shape by planar view toward the outer side of an entrance / exit. Be expanded.

Next, a procedure for opening the water-stopping doors 20A and 20B in the closed state and accommodating them on the wall surfaces W1 and W2 will be described.
First, the locking member 30 is removed, and the locking between the water blocking doors 20A and 20B is released. Thereafter, the water stop door 20A that is in contact with the floor surface F with a load is lifted upward to disengage the support piece 26 of the door bracket 25 from the notch 132 of the support member 13, while the water stop door 20A is moved to the wall surface W1. Swings to close slightly. Thereby, it will be in the state where door bracket 25 is located above support member 13, and in this state, water stop door 20A which was lifted upwards is lowered.

If it does so, the door bracket 25 will be supported by the upper surface 13a of the support member 13, and the water stop door 20A will be supported in the state which has the floating allowance S2. Thereafter, the water stop door 20A is swung toward the wall surface W1 to accommodate the water stop door 20A in the first position.
Here, since the water stop door 20A has the floating allowance S2, and swings the upper surface 13a of the support member 13, the water stop door 20A does not slide on the floor surface F with a load, and a smooth housing operation is performed. Can be realized.

According to the water stop device of the present embodiment described above, the water stop door 20A (20B) is located on the floor surface F when the water stop door 20A (20B) is at the first position arranged along the wall surfaces W1 and W2. It is supported by the support member 13 so that the load of the water stop door 20A (20B) is not applied, and when it reaches the second position for stopping the water at the entrance / exit, it is removed from the support region supported by the support member 13. Since it is configured to stop the entrance / exit in a state of being moved downward as compared to when it is at the position 1, the floor F is not moved until it reaches the second position from the first position. It will be in the state where the load of water stop door 20A (20B) is not applied. Accordingly, the water stop door 20A (20B) does not rub against the floor surface F during swinging until it reaches the second position from the first position. Therefore, the water stop door 20A (20B) can be smoothly closed at the second position.
As a result, it is possible to close the entrance / exit in a short period of time, for example, when the water has increased, and the operation of closing the water stop door 20A (20B) and the operation of opening the water stop door 20A (20B) after closing are easy. A water stopping device that can be sufficiently prevented is obtained.

  In the present embodiment, the water blocking doors 20A and 20B are swingably provided on the wall surfaces W1 and W2 via the support means 10A and 10B, and the water blocking doors 20A and 20B are connected to each other by the locking member 30. Therefore, for example, the size of the water blocking door 20A (20B) per sheet can be reduced compared to the case where only one wall surface W1 is provided, and the weight and space saving are reduced. Can be achieved.

  In addition, the water stop doors 20A and 20B are positioned in the second position so as to project outward in the shape of a substantially letter in plan view toward the outside of the entrance / exit, and thus do not project toward the outside of the entrance / exit. For example, compared with the case where it is linear in a plan view or the case where it is recessed in a substantially inverted shape in a plan view, it is strong against water pressure from the outside of the entrance and exit, and the water stop effect is enhanced. Therefore, even if water is rushed from the outside to the entrance of the building due to water increase or the like, it can be suitably dammed and water can be prevented from entering the building from the entrance.

  Moreover, since the water stop doors 20A and 20B (door body 21) are made of a hollow extruded profile made of an aluminum alloy, they can be easily manufactured. In addition, an extruded shape made of aluminum or an aluminum alloy has high dimensional accuracy and is lightweight for its strength.

In the present embodiment, the water stop doors 20A and 20B are arranged on both the wall surfaces W1 and W2. However, depending on the size of the doorway, the water stop doors 20A and 20B may be arranged only on one of them.
Moreover, the size (width) of the water stop doors 20A and 20B may be different.
