Description

  The present invention relates to a sheet-type inundation prevention device that is installed at an entrance of a building and prevents inundation into the building.

  For example, when a large amount of water is generated due to heavy rain, etc., there is a risk that the water may enter the building through the entrances and exits of houses, buildings, underground parking lots, and subways. Therefore, in order to prevent water from entering the building, there are some which are provided with an ingress prevention panel and an opening / closing door at these entrances.

  However, the flood prevention panel is generally heavy, and it is difficult for one worker to easily perform installation work, and there is also a problem of a storage place when not in use. In the case of a flood prevention panel, when processing and installing it, the flatness per door to which the water-stopping rubber hits, the verticality per side door, the parallelism, and the flatness per bottom door, High accuracy is required. This is because if these precisions are poor, water tightness is lowered and water leakage may occur. In the case of an open / close door, not only is the apparatus configuration enlarged and the installation location is restricted, but it is also expensive and unsuitable for ordinary homes and small buildings.

  In order to solve these problems, various flood prevention devices have been developed.

  For example, the inundation prevention device disclosed in Patent Document 1 closes the opening by lifting and fixing the sheet stored in the storage groove on the floor through the support frame formed on the wall surface of the opening of the building. Is configured to do. The inundation prevention device disclosed in Patent Document 2 stores two mounting columns with a waterproof sheet connected between them in the state of being laid under the floor of the passage opening, and stands up each mounting column during use. The passage opening is closed by being fixed to the wall of the passage. The inundation prevention device disclosed in Patent Document 3 is a device for preventing tide, and a pinch mechanism provided on each column by pulling up the water stop film stored on the floor of the entrance / exit of the building along the columns on both sides of the entrance / exit The doorway is closed by sandwiching and fixing the water-stopping film. The inundation prevention device disclosed in Patent Document 4 closes the doorway by pulling up the waterproof sheet stored in the floor pit of the doorway and pressing both sides of the waterproof sheet against the doors on both sides of the doorway with the waterproof sheet presser. Is configured to do. Furthermore, the inundation preventing device disclosed in Patent Document 5 stores the center sheet on the floor of the passage opening of the structure, while fixing the edge sheet in advance on both sides of the passage opening, The passage is closed by pulling up the seat, fixing the upper end of the seat to the left and right walls via a chain, and connecting the center seat and the edge seat with a watertight fastener.

  However, in the case of Patent Document 1, only both sides of the sheet are supported by the support frame, and there is a risk that water may enter between the support frame and the sheet. In Patent Document 2, when the mounting column is erected and fixed to the wall of the passage, it is necessary to have a configuration capable of realizing complete watertightness between the wall and the mounting column. In this case, it is technically difficult to make the mounting column detachable and maintain high watertightness. In Patent Document 3, in order to realize the water tightness between the water stop film and the support column, the water stop film is pressed against the support column by a clamping mechanism using a roller, and the configuration is extremely complicated. It is also difficult to achieve complete watertightness with this configuration. Patent Document 4 employs a mechanism that presses both sides of a waterproof sheet against a door stop, but in this case as well, there is a problem in maintaining complete watertightness. Furthermore, in the case of Patent Document 5, the edge sheet that is fixed in advance to both sides of the passage opening is merely pressed against the structure by the presser fitting, and cannot be said to have a structure that provides sufficient watertightness. . Moreover, the center part sheet | seat is fixed to the left and right walls using a chain for reinforcement, and a structure will become complicated.

<Explanation on the use of the sheet-type infiltration prevention device 10>
When the sheet-type flood prevention device 10 is not used, the operator pulls down the sliders 23a and 23b of the watertight fasteners 22a and 22b to release the engagement by the connecting elements 25a and 25b. Thereby, the waterproof sheet 12 and the connection sheets 12a and 12b are separated. Next, the pipe 24 is removed from the engagement plates 42a and 42b, and the waterproof sheet 12 is wound around the pipe 24 and stored in the storage unit 14 (FIG. 1B). In this case, the connection sheets 12a and 12b remain in the connection sheet pressing portions 32a and 32b of the first attachment portion 20a and the second attachment portion 20b, and only the waterproof sheet 12 is stored in the storage portion 14. Therefore, the operator can quickly open the entrance of the building by moving the sliders 23a and 23b downward and then only storing the waterproof sheet 12 in the storage unit 14. Moreover, this work can be easily performed by one person.

  Next, the operator closes the lid portion 48 of the storage portion 14 and the lid portions 30a and 30b of the first attachment portion 20a and the second attachment portion 20b (FIGS. 2 and 4C). In this case, the lid portion 48 of the storage portion 14 is formed with notches 54a and 54b. Accordingly, the lid portion 48 can close the storage portion 14 without interfering with the connecting sheet pressing portions 32a and 32b (FIG. 1B) whose lower end portion extends into the storage portion 14.

  In a state where the storage portion 14 is closed by the lid portion 48, a person or the like can freely pass through the doorway through the doors 16a and 16b. In this case, as shown in FIG. 4C, the lid portion 48 of the storage portion 14 is supported by the inner wall of the storage portion 14 by the leg portion 52, so that sufficient strength is ensured. Therefore, there is no possibility that the lid portion 48 is bent or deformed. A cushion member 50 made of rubber or the like is disposed at the lower end of the leg portion 52. Therefore, when a person walks on the lid part 48, the leg part 52 does not directly hit the inner wall of the storage part 14, and the generation of noise can be prevented.

  Next, the case where the waterproof sheet 12 of the sheet-type infiltration prevention device 10 is attached to the doorway in order to cope with heavy rain or the like will be described.

  First, the operator opens the lid portions 30a and 30b of the first attachment portion 20a and the second attachment portion 20b, and then opens the lid portion 48 of the storage portion 14 (FIGS. 1B and 3B). Next, the operator holds both ends of the pipe 24 and pulls up the waterproof sheet 12 from the storage unit 14. Next, the worker engages both end portions of the pipe 24 disposed on the upper end portion 27 of the waterproof sheet 12 with the engagement plates 42a and 42b of the main body portions 26a and 26b. Then, the operator pulls up the slider 23a of the watertight fastener 22a and the slider 23b of the watertight fastener 22b. When the sliders 23a and 23b are pulled up, the connecting elements 25a and 25b are engaged, and the connecting sheets 12a and 12b and the waterproof sheet 12 are connected. This completes the installation work of the waterproof sheet 12 and completes the measures against heavy rain (FIGS. 1A and 3A).

  In this case, the worker only needs to perform a very simple work of lifting the waterproof sheet 12 from the storage portion 14 and lifting the sliders 23a and 23b of the watertight fasteners 22a and 22b. One worker can easily perform the work. Can be carried out. Further, the waterproof sheet 12 can be held by the main body portions 26a and 26b only by engaging both end portions of the pipe 24 of the upper end portion 27 with the engagement plates 42a and 42b, so that the attachment work is very easy.

  Furthermore, the connection sheets 12a and 12b connected to both sides of the waterproof sheet 12 are fixed in a watertight manner in the vertical direction by the connection sheet pressing portions 32a and 32b. That is, the linear members 34a, 36a, 34b, 36b are in contact with the left and right sides of the connecting sheets 12a, 12b over the entire range in the vertical direction, and these linear members 34a, 36a, 34b, 36b are interposed therebetween. The pressing plates 38a and 38b are fixed by a plurality of bolts 40a and 40b. Accordingly, the connecting sheets 12a and 12b are sandwiched and fixed between the main body portions 26a and 26b of the first mounting portion 20a and the second mounting portion 20b and the pressing plates 38a and 38b without any gap. Therefore, there is no possibility that water may enter the doors 16a and 16b from the first mounting portion 20a and the second mounting portion 20b. Moreover, the connecting sheets 12a and 12b and the waterproof sheet 12 are connected by watertight fasteners 22a and 22b. In this case, since the upper end portion 27 of the waterproof sheet 12 is engaged with the engagement plates 42a and 42b of the first attachment portion 20a and the second attachment portion 20b, the waterproof sheet 12 is deformed by water pressure. However, the situation where the waterproof sheet 12 falls off does not occur. Further, the lower end portion 29 of the waterproof sheet 12 is fixed in a watertight manner in the horizontal direction by a waterproof sheet pressing portion 32c having the same configuration as the connecting sheet pressing portions 32a and 32b (FIG. 4C). Therefore, there is no possibility that water may enter the doors 16a and 16b from the lower end 29 of the waterproof sheet 12. As a result, the sheet-type water intrusion prevention device 10 can reliably prevent water from entering the doorway.

The waterproof sheet 62 is composed of a single sheet that connects the connecting sheets 62a and 62b and the sheet parts 62c and 62d on the lower end part 63 side. The lower end portion 63 of the waterproof sheet 62 is watertightly fixed to the inner wall of the storage portion 64 by the waterproof sheet pressing portion 32c. The side portions of the connecting sheet 62a and the sheet portion 62c, the side portions of the sheet portion 62c and the sheet portion 62d, and the side portions of the sheet portion 62d and the connecting sheet 62b are watertight fasteners 66a and 66b (second It is connected in a separable state by watertight fasteners) and 66c. Pipes 68 and 70 are inserted into upper end portions 65c and 65d of the sheet portions 62c and 62d. The number of watertight fasteners 66a to 66c is the number obtained by adding 1 to the number of pipes 68 and 70 that support the upper end portions 65c and 65d of the waterproof sheet 62. Each pipe 68 and 70 protrudes by a predetermined amount from both ends of the upper end portions 65c and 65d. The sheet portions 62c and 62d are stored in the storage portion 64 when the sheet-type infiltration prevention device 60 is not used.

  On the floor between the first mounting portion 20a and the second mounting portion 20b, a support column 72 that can be attached to and detached from the doorway is erected. On the upper portion of the support column 72, an engagement plate 74 is provided for engaging each end portion of the opposed pipes 68, 70. The number of support pillars 72 is a number obtained by subtracting 1 from the number of divided sheet portions 62c and 62d.

<Explanation on the use of the sheet-type infiltration prevention device 60>
When the sheet-type flood prevention device 60 is not used, the operator pulls down the sliders 69a to 69c of the watertight fasteners 66a to 66c and releases the engagement by the connecting elements 71a to 71c. Thereby, the connection sheet 62a and the sheet part 62c, the sheet part 62c and the sheet part 62d, and the sheet part 62d and the connection sheet 62b are separated. Next, the pipes 68 and 70 are removed from the engagement plates 42 a, 74 and 42 b, and the sheet parts 62 c and 62 d are wound around the pipes 68 and 70 and stored in the storage part 64. And an operator closes the cover part 76 of the accommodating part 64, and the cover parts 30a and 30b of the 1st attachment part 20a and the 2nd attachment part 20b. In this case, notches 78 a and 78 b are formed at both ends of the lid 76. Accordingly, the lid portion 76 can close the storage portion 64 without interfering with the connecting sheet pressing portions 32a and 32b. In addition, the support pillar 72 between the 1st attachment part 20a and the 2nd attachment part 20b can be extracted from a floor, and can be accommodated in the accommodating part 64 with the sheet parts 62c and 62d.

  Thus, by storing the two sheet portions 62c and 62d in the storage portion 64, a wide frontage can be secured at the entrance / exit.

  On the other hand, when attaching the waterproof sheet 62 of the sheet-type flood prevention device 60 to the doorway, the operator attaches the lid portions 30a and 30b of the first attachment portion 20a and the second attachment portion 20b and the lid portion 76 of the storage portion 64. open.
