(Embodiment 1)
FIG. 1 is a perspective view showing an overall configuration of a waterstop device 1 according to Embodiment 1 of the present invention, FIG. 2 is a plan view thereof, and FIG. 3 is a front view thereof. As shown in FIGS. 1 to 3, the water stop plate device 1 according to the first embodiment includes a water stop plate 2 that is installed at a doorway 10 of a building such as a building, a subway, and an underground mall and can be manually undulated. It is provided and is mainly made of a material having excellent weather resistance such as a steel plate and an aluminum plate.

  And the storage groove | channel 3 which is formed in the outer side of the entrance / exit 10 and has the opening part which becomes substantially flush with the floor surface 9 of the entrance / exit 10 is provided, and the water stop plate 2 is fallen in the storage groove 3 and stored. The first posture and the second posture that is raised through a predetermined path by being lifted on the side opposite to the doorway 10 and drawn toward the doorway 10 side. For this purpose, a grip portion 23 is provided on the distal end side of the water stop plate 2.

  Here, left and right support columns 4 having a square cross section are disposed at the entrance / exit 10 at a predetermined interval. The base part of the left and right support columns 4 is embedded under the floor surface 9, and the tip part thereof is set to be higher than the water stop plate 2 in the second posture. Covers 5 are respectively connected to the storage groove 3 side of the left and right support columns 4 by hinges 5a (see FIGS. 6A and 6B), so that the door can be opened and closed in a so-called double door opening direction (B direction in FIG. 2). It is attached as possible.

  The storage groove 3 has a box shape in which the whole is slightly flat and the upper part is opened. The storage groove 3 is just outside the left and right support columns 4 and has a depth (about 10 cm) with a slight margin added to the thickness of the water stop plate 2. ), It is buried deeply, so there are almost no restrictions on the installation location, and the construction work is greatly simplified. The opening of the storage groove 3 is covered with a lid (corresponding to a lid) 6 that can be opened and closed by rotating to the side opposite to the left and right columns 4 (direction C in FIG. 4A). . Due to the presence of the lid 6, heavy objects or the like are not placed directly on the water stop plate 2. For this reason, it becomes possible to reduce in weight by making the water stop board 2 into simple structures, such as a flat plate reinforced with the rib material, for example.

  Further, when the water stop plate 2 is in the first posture and the second posture, the lid 6 can be closed respectively. In this way, by setting the lid 6 in the closed state even during operation, it is possible to prevent the foot from being stepped and damaged by evacuation during a disaster. Therefore, it is preferable to provide an appropriate slip stopper on the surface of the lid 6.

  FIG. 4 is an explanatory diagram showing an enlarged view of part A in FIG. 1, where (a) shows the operation around the water stop plate 2 in the first posture, and (b) shows the operation around the water stop plate 2 in the second posture. ing. The lid 6 is provided with a foldable flapper 6a at the front end of the left and right support columns 4, and when the water stop plate 2 is in the first posture, as shown in FIG. 4 (a), the flapper 6a is unfolded. When the water stop plate 2 is in the second posture, the flapper 6a is folded so as not to interfere with the water stop plate 2 as shown in FIG. 4 (b). Thereby, the clearance gap between the lid | cover 6 and the floor surface 9 can be decreased.

  In the first posture, the water stop plate 2 has a rectangular shape that can be stored in the storage groove 3, and the flapper 6 a of the lid 6 remains unfolded as shown in FIG. In a state opened to the opposite side (C direction) to the left and right support columns 4, it can be opened and closed by rotating in the opposite direction (D, E direction) from the lid 6. Further, as shown in FIG. 4B, the waterstop plate 2 is folded by rotating the flapper 6a of the lid 6 downward (F direction) around the rotation shaft 6b as shown in FIG. It is closed to the 4th side (G direction) and cannot be opened and closed.

  The movement path at the time of opening and closing the water stop plate 2 is defined by the left and right support column 4 side on the back surface of the water stop plate 2 in the first posture and the guide 22 for guiding it. As the guide 22, for example, a rail member as shown in FIGS. 4A and 4B is adopted, but the bottom plate of the storage groove 3 may be adopted as it is.

  The water stop plate 2 in the second posture is locked by a lock mechanism 8 via seals (water stop packing) 7 on the left and right support columns 4 side. Thereby, it can stop reliably in the 2nd attitude | position which the water stop plate 2 stood up. Here, FIG. 6 is an explanatory view showing the lock mechanism 8 of the waterstop device 1, wherein (a) is a plan view and (b) is a side view.

  For example, the lock mechanism 8 is provided on the left and right upper end sides and the left and right lower end sides of the water stop plate 2 in the second posture, and is provided on the water stop plate 2 as shown in FIGS. The contact plate 2a, a rotating shaft 8a fixed in the cover 5 of the left and right support columns 4, a long operating lever 8b rotatably attached around the rotating shaft 8a, and a stop in the longitudinal direction of the operating lever 8b And a protrusion 8c provided at a position where the water plate 2 can come into contact with the contact plate 2a.

  Here, when the water stop plate 2 is in the first posture, the cover 5 is closed, and the operation lever 8b is stored in an upright posture in the cover 5. On the other hand, when the cover 5 is opened and the water stop plate 2 is in the second posture, the operation lever 8b rotates in the H direction around the rotation shaft 8a, and the projection 8c is brought into contact with the water stop plate 2. It abuts on the plate 2a and presses the water stop plate 2 toward the left and right support columns 4 side. Thereby, the water stop board 2 of said 2nd attitude | position can be reliably locked to the left-right support | pillar 4 side. In addition, since the water stop plate 2 in the first posture is stored in the storage groove 3 and the lock mechanism 8 is stored in the cover 5 in normal times, it is possible to prevent dust and the like from being mixed and erroneous operation in both cases. .

  5A and 5B are explanatory views showing the structure of the seal 7 of the water stop plate device 1, where FIG. 5A is before the water stop plate 2 and the left and right support columns 4 are in contact, and FIG. The state after contact with the support 4 is shown. As shown in FIG. 5A, the seal 7 is provided on the water stop plate 2 side, and includes a first seal provided with a regulating member 71 that regulates deformation in the width direction of the seal body 72, and the left and right support column 4 sides. And a second seal composed of a seal body 73 wider than the regulating member 71. The restricting member 71 is made of metal, but the seal body 72 is made of rubber. The first seal is attached to each of the left and right sides and the lower side of the water stop plate 2 in the second posture, and the second seal is a side of the left and right columns 4 and the storage groove 3 facing the first seal. Is attached to each.

  As shown in FIG. 5B, in the second posture, the seal body 73 of the first seal is in a state where the seal body 73 of the second seal is in contact with the regulating member 71 of the first seal. 72. Thereby, it can stop still more reliably by the 2nd attitude | position which the water stop plate 2 stood up. In the normal state, the second seal is protected by the cover 5 of the left and right support columns 4 and the first seal is protected by the lid 6 of the storage groove 3.

  Hereinafter, schematic operation of the waterstop device 1 will be described. That is, as shown in FIGS. 1 to 3, in the normal state, the water stop plate 2 is stored in the storage groove 3 in the first lying down posture, and its opening is covered with the lid 6. At this time, the flapper 6a of the lid 6 is in an unfolded state, extends to the floor surface 9 side, and is received by an auxiliary member (not shown) attached to the lower side of the floor surface 9. Thereby, the floor surface 9 of the entrance / exit 10 of a building and the surface of the lid | cover 6 are flush, and it is completely barrier-free. At this time, the water stop plate 2 and the first seal on the water stop plate 2 side of the seal 7 are covered with the lid 6, and the second seal on the left and right support column 4 side is covered with the cover 5. Therefore, both are invisible from the outside. The same applies to the lock mechanism 8. This prevents erroneous operation of the water stop plate 2 during normal operation, deterioration of the seal 7, contamination of dust, erroneous operation of the lock mechanism 8 and the like, and also improves the appearance.

  In an emergency, when the cover 5 of the left and right support columns 4 is doubled (in the direction B in FIG. 2), the second seal of the seal 7 and the lock mechanism 8 can be seen from the outside. Next, by lifting with the gripping part (not shown) of the lid 6 of the storage groove 3, it is rotated to the opposite side (C direction in FIG. 4) from the left and right support columns 4 until it stops at the stopper (not shown). Open state. At this time, the flapper 6 a of the lid 6 rotates around the rotation shaft 6 b by its own weight and is folded to the back side of the lid 6.

  Next, the water stop plate 2 is lifted by pulling it up with the holding portion 23 of the water stop plate, so that the water stop plate 2 is set in the second posture. At this time, as shown in FIGS. Is separated from the left and right support columns 4, which are guided by the guide 22 and move to the left and right support columns 4. Then, the posture of the water stop plate 2 continuously changes from the horizontal first posture to the vertical second posture through the inclined intermediate posture. The basic operation is to rotate the water stop plate 2 with a contact point with the guide 22 as a fulcrum, and the distance to horizontally move the water stop plate 2 on the guide 22 is small. Combined with conversion, less labor is required.

  Then, the water stop plate 2 in the second posture is pressed against the left and right support columns 4 and the side walls of the lower storage groove 3 with the seal 7 interposed therebetween, and is locked by the lock mechanism 8. At this time, as shown in FIGS. 5A and 5B and FIGS. 6A and 6B, the regulating member 71 of the first seal on the water stop plate 2 side is a seal of the second seal such as the left and right support columns 4. Opposite to the main body 72, the upright control lever 8b in the cover 5 is rotated downward (H direction) around the rotation shaft 8a.

  Then, the projection 8c of the operation lever 8b presses the surface while sliding on the contact plate 2a of the water stop plate 2. With this pressing force, the regulating member 71 of the first seal on the water stop plate 2 side abuts on the seal main body 72 of the second seal such as the left and right support columns 4 and raises the center thereof, and then the regulating member of the first seal Abutting on the seal main body 72 in 71, this contact state is maintained. Thereafter, the lid 6 of the storage groove 3 is closed again. At this time, the flapper 6 a of the lid 6 is rotated around the rotation shaft 6 b by its own weight and is folded to the lower side of the lid 6. Therefore, it is possible to prevent the tip of the lid 6 and the flapper 6a from approaching or coming into contact with the intermediate portion of the water stop plate 2 so that the water stop plate 2 is inadvertently laid down. When returning from an emergency to a normal time, generally the reverse procedure is taken, but only the flapper 6a of the lid 6 is manually deployed to be flush with the floor surface 9.

  Here, this inventor made the trial manufacture of the water stop board apparatus 1, and implemented the operation check and the waterproof performance test. Specifically, it was confirmed that the operator can manually undulate the water stop plate 2 having a width of about 1 m and a height of about 60 cm and the water stop plate 2 having a width of about 2 m and a height of about 60 cm. Above, the water filling test was conducted, and it was confirmed that there was no water leakage.

  As described above, according to the water blocking plate device 1 according to the first embodiment, the water stop plate device 1 is formed on the outer side of the right and left columns 4 attached to the entrance 10 of the building, and is substantially flush with the floor surface 9 of the entrance 10. The storage groove 3 having an opening with a lid 6 that becomes one, and the waterstop plate 2 is in a first posture stored in a collapsed manner in the storage groove 3 and a grip portion 23 on the opposite side to the left and right support columns 4. Since it is lifted and pulled to the left and right support columns 4 side, it has a second posture that is guided and raised by the guide 22, so that it takes time and effort to secure and transport the water stop plate 2. In addition to making it unnecessary, there is no step in normal use as well as in an emergency, so there is no need to step over and fall. Moreover, since the thickness of the storage groove 3 for storing the undulating water stop plate 2 is extremely thin, there is no restriction on the installation location, and the construction work can be greatly simplified.

  Further, when the water stop plate 2 is in the first posture and the second posture, the lid 6 is closed to prohibit the raising and lowering operation of the water stop plate 2, while the water stop plate 2 is in the first posture and the second posture. Opening the lid 6 allows the raising and lowering operation of the water stop plate 2 when it is between the postures, so that it is possible to prevent erroneous operation due to manual operation, and compared to the conventional method of pushing in with an electric cylinder or the like. Because each stage is simple in operation, there are few failures, it can respond quickly to emergencies, and maintenance can be simplified considerably.

  Further, the lid 6 is rotatable about the opposite side of the opening of the storage groove 3 from the entrance / exit 10 and includes a foldable flapper 6a at the front end of the lid 6 so that the water stop plate 2 is in the first posture. The flapper 6a is unfolded when the water stoppage is reached, while the flapper 6a is folded so as not to interfere with the waterstop plate 2 when the waterstop plate 2 is in the second posture. And more complete barrier-free can be realized.

(Embodiment 2)
By the way, the cover 6 of the said Embodiment 1 can be set as a simpler structure. FIG. 7 is an explanatory view showing the normal time of the water stop plate device 1 ′ according to the second embodiment of the present invention, and FIG. 8 is an explanatory view showing an emergency (1) of the water stop plate device according to the second embodiment. 3 is explanatory drawing which shows the emergency (2) of the waterstop apparatus which concerns on this Embodiment 2, Comprising: Each (a) is a side view, (b) is a top view. The components of the water stop plate device 1 ′ according to the second embodiment are the same as those of the first embodiment except for the water stop plate 2 ′, the storage groove 3 ′, and the lid 6 ′. That is, as shown in FIGS. 7 (a) and 7 (b), the waterstop device 1 'is installed at the entrance / exit 10 of a building such as a building, a subway, an underground mall, etc. and can be manually raised and lowered. It is made of materials with excellent weather resistance, such as steel plates and aluminum plates.

  The storage groove 3 ′ is formed immediately outside the doorway 10 and has an opening that is substantially flush with the floor surface 9 of the doorway 10. The water stop plate 2 ′ falls in the storage groove 3 ′. The first posture stored in this way and the second posture that is raised through a predetermined path by being lifted on the side opposite to the entrance 10 and drawn toward the entrance 10 side. For this purpose, inverted U-shaped gripping portions 23 ′ are provided at the left and right ends of the water stop plate 2 ′. Hereinafter, detailed description of components common to the first embodiment will be omitted.

  Here, the left and right support columns 4 are disposed at the entrance / exit 10 at a predetermined interval. The base part of the left and right support columns 4 is embedded under the floor surface 9, and the tip part thereof is set to be higher than the water stop plate 2 'in the second posture.

  The storage groove 3 ′ is a box shape that is slightly flat and open upward, and is located just outside the left and right support columns 4, and has a depth that adds a slight margin to the thickness of the water stop plate 2 ′ ( Since it is dug down by about 10 cm), there are almost no restrictions on the installation location, and the construction work is greatly simplified. The opening of the storage groove 3 'is removed by shifting to the opposite side to the entrance 10 and covered with a lid (corresponding to a lid) 6' that can be opened and closed by being attached to the entrance 10 side. . The lid 6 ′ is intended to be installed at a place where a vehicle passes, such as a doorway of a factory, and is designed to reduce the weight while ensuring its strength. Due to the presence of the lid 6 ', a car or the like cannot be placed directly on the water stop plate 2'. For this reason, it is possible to reduce the weight by making the water stop plate 2 ′ a simple structure such as a flat plate reinforced with a rib member.

  Further, when the water stop plate 2 ′ is in the first posture and the second posture, the lid 6 ′ can be closed with the gripping portion 61 ′. In this way, by closing the lid 6 'even during operation, it is possible to prevent the foot from being stepped on and being damaged by evacuation during a disaster. Therefore, it is preferable to provide a suitable anti-slip on the surface of the lid 6 '. Note that the gripping portion 61 ′ is different from that of a normal manhole cover, and in a state where the opening of the storage groove 3 ′ is closed by the cover 6 ′, dust or water does not enter the storage groove 3 ′. Are preferred.

  As shown in FIG. 8 (b), the lid 6 ′ is divided into two parts by left-right distribution of the central axis I of the storage groove 3 ′, and when the water stop plate 2 ′ is in the first posture, As shown in FIG. 9B, when the water stop plate 2 ′ is in the second posture while completely closing the opening of the storage groove 3, as shown in FIG. 9B, it interferes with the water stop plate 2 ′. In order to prevent this, the opening of the storage groove 3 ′ is completely closed by retreating by the thickness of the water stop plate 2 ′. Thereby, the clearance gap between the lid | cover 6 'and the floor surface 9 can be decreased. For this purpose, stepped notches 62 ′ are formed at two appropriate positions in contact with the left and right columns 4, 4 of the lid 6 ′.

  In the first posture, the water stop plate 2 ′ has a rectangular shape that can be stored in the storage groove 3 ′. As shown in FIGS. In a state where the opening is opened by being shifted from the opening of the storage groove 3 ′, it can be opened and closed by rotating it toward the doorway 10 (J direction in the figure or the opposite direction). Further, in the second posture, the water stop plate 2 ′ is retracted by the thickness of the water stop plate 2 ′ as shown in FIGS. As a result of abutting on the opening of the water and attaching to the water stop plate 2 ′, the water stop plate 2 ′ cannot be opened and closed.

  The movement path when the water stop plate 2 ′ is opened and closed is defined by the left and right struts 4 side on the back surface of the water stop plate 2 ′ in the first posture and a guide (not shown) for guiding it. As this guide, a rail member provided with an oval hole (not shown) through which pins (not shown) provided on the left and right sides of the water stop plate 2 are inserted is adopted, but the bottom plate of the storage groove 3 ′ is adopted as it is.

  The water stop plate 2 ′ in the second posture is locked to the left and right support columns 4 by a lock mechanism 8 via seals (water stop packing) 7. Accordingly, water can be reliably stopped in the second posture in which the water stop plate 2 ′ stands up.

  Hereinafter, a schematic operation of the waterstop device 1 'will be described. That is, as shown in FIGS. 7 (a) (b) to 9 (a) (b), normally, the water stop plate 2 ′ is stored in the storage groove 3 ′ in the first lying down posture. The opening is covered with a lid 6 '. At this time, the lid 6 ′ completely closes the opening of the storage groove 3 ′ and extends toward the floor surface 9. Thereby, the floor surface 9 of the entrance 10 of the building and the surface of the lid 6 'are flush with each other and are completely barrier-free. At this time, since the water stop plate 2 ′ and the first seal on the water stop plate 2 ′ side of the seal 7 are covered with the lid 6 ′, they cannot be seen from the outside. This prevents erroneous operation of the water stop plate 2 ′ during normal operation, deterioration of the seal 7, and dust contamination.

  In an emergency, insert a dedicated tool or the like (not shown) into the grip 61 'of the lid 6' of the storage groove 3 'and hook the lid 6' so that they are individually shifted to the opposite side to the left and right columns 4 and stored. It is assumed that the opening of the groove 3 ′ is wide open.

  Next, by pulling up with the gripping portion 23 ′ of the water stop plate 2 ′, the water stop plate 2 ′ is raised to a second posture. At this time, the water stop plate 2 ′ is separated from the left and right support columns 4. It is guided by the guide and moves to the left and right support columns 4 side. Then, the posture of the water stop plate 2 ′ continuously changes from the horizontal first posture to the vertical second posture through the inclined intermediate posture. The basic operation is to rotate the pin of the water stop plate 2 'within the oval hole of the guide, and the distance for horizontally moving the water stop plate 2' within the oval hole of the guide is: Since it becomes a little, the labor can be reduced with the weight reduction of the water stop plate 2 ′.

  Then, the water stop plate 2 ′ in the second posture is pressed against the left and right support columns 4 and the side walls of the storage groove 3 ′ under the right column 4 with the seal 7 interposed therebetween, and is locked by the lock mechanism 8.

  Thereafter, the lid 6 'of the storage groove 3' is closed again. At this time, the dedicated tool or the like is inserted into the gripping portion 61 ′ of the lid 6 ′ of the storage groove 3 ′, and the lid 6 ′ is hooked to individually shift to the left and right columns 4, and the left and right columns 4 are covered with the lid. A 6 'cutout 62' is fitted. Then, it is possible to prevent the tip end of the lid 6 ′ from approaching or contacting the intermediate portion of the water stop plate 2 ′ and the water stop plate 2 ′ from being accidentally tilted. When returning from an emergency to a normal time, the procedure reverse to the above is generally taken. Here, the present inventor made a prototype of the waterstop device 1 ′, performed an operation check and a waterproof performance test, and obtained a good result for this.

  As described above, according to the water blocking plate device 1 ′ according to the second embodiment, the water stop plate device 1 ′ is formed just outside the left and right support columns 4 attached to the entrance 10 of the building, and is substantially the same as the floor surface 9 of the entrance 10. A storage groove 3 ′ having an opening with a lid 6 ′ that is flush with the storage groove 3 ′ is provided. Since it has a second posture that is raised by being guided by a guide by being lifted by the grip portion 23 'and pulled toward the left and right support columns 4, it can be used for securing and transporting the water stop plate 2'. Such labor and time are not required, and there is no step in an emergency as well as in normal use, so that a foot is not dropped and falls. Further, since the thickness of the storage groove 3 ′ for storing the undulating water stop plate 2 ′ is extremely thin, there is no restriction on the installation location, and the construction work can be greatly simplified.

  Further, when the water stop plate 2 ′ is in the first posture and the second posture, the lid 6 ′ is closed to prohibit the raising and lowering operation of the water stop plate 2 ′, while the water stop plate 2 ′ is in the first posture. When it is between the posture and the second posture, by opening the lid 6 ', the raising and lowering operation of the water stop plate 2' is allowed. Compared to the push-in method, each stage and operation are simple, so there are few failures, quick response to emergency emergencies, and maintenance can be simplified considerably.

  The lid 6 ′ can be removed by shifting the opening of the storage groove 3 ′ to the side opposite to the entrance 10, and can be attached to the entrance 10, so that the lid and floor can be more simply configured. A more complete barrier-free operation can be realized by reducing the gap with the surface.

  In the first embodiment, the lid 6 substantially covers the opening of the storage groove 3. However, as in the second embodiment, the lid 6 may be divided into a plurality of parts. However, in order to ensure water stopping performance, it is preferable that the water stopping plates 2 and 2 'are integrated. Moreover, when the entrance / exit 10 is wide, an intermediate strut similar to the left and right struts 4 may be added, and a plurality of the water stop plate devices 1, 1 ′ may be provided side by side.

  Further, in the first embodiment, the flapper 6a is provided on the lid 6, but instead of this, a flapper that can be folded on the side opposite to the flapper 6a may be provided on the floor surface 9 side. . Alternatively, as in the second embodiment, a lid 6 'that opens and closes by shifting from the opening, such as a manhole cover, may be provided. Further, instead of covering the openings of the storage grooves 3 and 3 ′ with the lids 6 and 6 ′, the openings of the storage grooves 3 and 3 ′ may be directly covered with the water blocking plates 2 and 2 ′. In that case, there is an advantage that the lids 6 and 6 'are unnecessary and the storage grooves 3 and 3' are further thinned.

  In the first and second embodiments, the water stop plates 2 and 2 'are reduced in weight as a simple structure such as a flat plate reinforced with a rib material, but the water stop plates 2 and 2' are made of aluminum, for example. Therefore, the weight can be reduced, and if there is no problem in strength, the weight can be further reduced by combining the two. The same applies to the structures and materials of the lids 6 and 6 '.

  In the first and second embodiments, the water stop plates 2 and 2 ′ in the first posture stored in the storage grooves 3 and 3 ′ are held on the opposite sides of the left and right columns 4. It is said that the water-stopping plates 2 and 2 'in the first posture are lifted on the side opposite to the entrance 10 so that the right and left columns are lifted. By rotating around the lower rotation center of 4, the second posture may be raised. In that case, since the horizontal movement of the water stop plates 2 and 2 ′ is eliminated, the movement effort can be further reduced, and the water stop plates can be undulated easily and quickly. In addition, the grip portion 23 of the first embodiment is fixed to the tip (upper end in the second posture) opposite to the entrance / exit 10 of the water stop plate 2 in the first posture, like the grip portion 23 ′ of the second embodiment. It may be a simple one such as an inverted U-shape.

  Moreover, in the said Embodiment 1, the 2nd seal | sticker of the seal 7 by the side of the right-and-left support | pillar 4 and the lock mechanism 8 are all covered with the cover 5, and in the said Embodiment 2, this cover 5 is abbreviate | omitted. However, a similar cover 5 may be provided.

  Further, in some cases, the seal 7 may not be provided on the left and right support columns 4 side, and a simpler configuration may be applied only to the water stop plates 2 and 2 ′. A simple configuration may be applied only where necessary.
