Description

  The present invention relates to a tsunami countermeasure door, and more particularly to a tsunami countermeasure door that can withstand a large tsunami.

  It is preferable to secure a building that can be easily accessible when a large tsunami strikes. However, it can be convinced that tsunami shelters that are not used at all in normal life are not widely spread due to the excessive economic burden not only for new construction but also for maintenance. In addition, if possible, it is necessary to protect factory equipment and products that do not fit in the tsunami shelter. Therefore, a tide door has been developed that is constructed by connecting a tide plate to the lower end of a shutter curtain that is guided by guide rails arranged on the left and right of the opening of a building used for normal living and that opens and closes. (For example, refer to Patent Document 1).

  However, the great magnitude (M) 9 earthquake that struck Japan's Tohoku and Kanto regions on March 11, 2011, left a large tsunami that would easily exceed a 10 meter high seawall. It is clear that the tide door of Patent Document 1 cannot hold the tsunami generated and unimaginably large.

  In other words, in the case of a large tsunami, the houses, automobiles, ships, etc. that were destroyed by the direct hit were involved, and the huge amount of debris and even the flames of oil leaked from the tanks were brought into the living area in a very short time. The reinforced concrete structure that remained slightly there flowed unrelentingly from the opening, and the inside was completely swept away by the following pulling wave.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a tsunami countermeasure door that can withstand a large tsunami.

  The present invention is a tsunami countermeasure door that can be installed in an opening on at least one wall surface of a building, and the opening can be opened and closed by running along rails provided above and below or on the left and right of the opening. And a door pressing mechanism capable of pressing the door body against the wall surface around the opening through a seal when the door body is moved to a position covering the entire opening. It is characterized by that. The building itself is any structure that can withstand a large tsunami (for example, a low-rise / middle-rise / high-rise reinforced concrete structure is preferable), and not only the tsunami shelter but also a private residence used for normal living.・ Includes stores, factories, and other public facilities such as prefectural municipal offices.

  According to the present invention, by running along a rail provided on the top and bottom or the left and right of the opening, the door main body capable of opening and closing the opening, and the position where the door main body covers the entire opening. Since the door main body is equipped with a door pressing mechanism that can press the door body against the wall surface around the opening through the seal portion when the vehicle travels, the opening of the building should be opened when a tsunami strikes. It is sealed to prevent debris from flowing from the opening, and it is possible to safely protect not only humans who have evacuated there but also factory equipment and products until the influence of the tsunami is eliminated.

  Further, the seal portion includes a first seal provided on the door body and a second seal provided on the wall surface, and the center axes in the width direction of both seals at the time of pressing are shifted from each other in the width direction. It is preferable.

  In this case, the seal portion includes a first seal provided on the door main body and a second seal provided on the wall surface, and the central axes in the width direction of both seals at the time of pressing are mutually in the width direction. Since it has shifted | deviated, the contact | abutting in the perimeter of seals can be ensured and an opening part can be reliably sealed by the door main body.

  Moreover, it is preferable that the both seals have substantially the same width, and the center axis in the width direction of both seals at the time of pressing is shifted from each other by half in the width direction.

  In this case, both the seals have substantially the same width, and the center axis in the width direction of both seals at the time of pressing is shifted from each other by half in the width direction. Further, the opening can be more reliably sealed with the door body.

  The door pressing mechanism is configured to press the door body against a wall around the opening when the door body is moved to a position covering the whole opening and the door body is mounted. It is preferable to further include a groove portion that guides the carriage with an upward gradient with respect to the pressing direction.

  In this case, the door pressing mechanism presses the door main body against the wall surface around the opening and the carriage on which the door main body is mounted when the door main body travels to a position covering the entire opening. When the tsunami hits, it is easy to seal the opening with the door body, and after the tsunami leaves When a person escapes from a building, the opening becomes easy to open.

  Moreover, it is preferable to arrange | position the cart and groove part of the said door press mechanism in a position lower than the said opening part.

  In this case, since the carriage and the groove of the door pressing mechanism are arranged at a position lower than the opening, a so-called barrier-free structure causes a person evacuating in the building to fall over the opening, or to install factory equipment or products. It is possible to avoid unforeseen circumstances such as making it difficult to carry it into the building.

  Moreover, it is preferable that the said seal part has both fire resistance and water resistance.

  In this case, since the seal portion has both fire resistance and water resistance, the water resistance and fire resistance of the door can be greatly increased.

  According to the present invention, by running along a rail provided on the top and bottom or the left and right of the opening, the door main body capable of opening and closing the opening, and the position where the door main body covers the entire opening. Since the door main body is equipped with a door pressing mechanism that can press the door body against the wall surface around the opening through the seal portion when the vehicle travels, the opening of the building should be opened when a tsunami strikes. It is sealed to prevent debris from flowing from the opening, and it is possible to safely protect not only humans who have evacuated there but also factory equipment and products until the influence of the tsunami is eliminated.

It is a conceptual diagram of the building provided with the tsunami countermeasure door which concerns on one Example of this invention. It is a conceptual diagram of this tsunami countermeasure door. It is a block diagram which shows an example of the control system around the door for this tsunami countermeasure.

  FIG. 1 is a conceptual diagram of a building 4 provided with tsunami countermeasure doors 6 and 9 according to an embodiment of the present invention. The building 4 provided with the tsunami countermeasure doors (hereinafter referred to as doors) 6 and 9 according to the present embodiment is a reinforced concrete structure having one floor and only one room, as shown in FIG. This building 4 is not only a so-called tsunami shelter, which is a structure that itself can withstand a large tsunami and can evacuate when a tsunami hits it. Including residential buildings, stores, factories, and other public facilities such as prefectural municipal offices. The opening 5 where a person in and out of the building 4 enters and exits is provided with a door 6, and the opening 7 through which a person looks into the outside is also provided with a door 9 through a window glass 8.

  FIG. 2 is a conceptual diagram of the door 6, where (a) is a front view and (b) is a side view. The door 6 is mainly made of a material excellent in both water resistance and fire resistance such as a steel plate. For example, as shown in FIGS. The door body 60 is caused to travel in the left-right direction along the upper and lower rails 61, 62 of the opening 5. Then, the opening 5 is opened and closed by the door main body 60, and the door main body 60 is moved in the front-rear direction immediately before closing, so that the door main body 60 is drawn toward the inside of the building 4. ing.

  That is, the door main body 60 includes upper and lower rollers 63 and 64, and the upper roller 63 is guided by the upper rail 62 and the lower roller 64 is guided by the lower rail 61. In general, doors that are opened and closed by running the door body in the left-right direction are widely used, but in order to make the door body run smoothly, there is a slight gap between the door body and the structural wall. is necessary. However, if there is a gap, water or flame will enter the room from there. On the other hand, if the gap is eliminated, the door body and the structural wall may come into contact and the door body may not move smoothly.

  Therefore, for example, when the door 6 is moved to a position that covers the entire opening 5 with a handle (not shown), the door 6 is directed toward the wall surface around the opening 5 ( Although not clearly shown in the figure, the carriage 65 guided by the groove 65a formed to be slightly upwardly inclined, and the door main body 60 guided by the carriage 65 when the person operates a handle (not shown) around the opening 5 And a hydraulic pump 67 for driving the hydraulic cylinder 68. The hydraulic cylinder 68 is firmly supported by a structure 66 such as H-shaped steel disposed on the left and right sides of the door body 60 at a position covering the entire opening 5. Each element 65, 65a to 68 corresponds to a door pressing mechanism.

  Further, the seal portion 69 is also made of a rubber material excellent in both water resistance and fire resistance, and the seal packing 691 as a first seal provided over the entire periphery of the door body 60, and the opening portion. 5 and a seal packing 692 serving as a second seal provided over the entire circumference of the wall surface of the five circumferences. Both seal packings 691 and 692 have substantially the same width (for example, in FIG. The center axes in the width direction of the seal packings 691 and 692 at the time of pressing are shifted from each other by half of the width direction. Thereby, the contact | abutting in the perimeter of seal packing 691,692 is ensured, and the water resistance and fire resistance of the door 6 are improved significantly.

  Here, the lower rail 61, the carriage 65, and the groove 65a have a so-called barrier-free structure that does not protrude on the ground. This is not only for ensuring the habitability of elderly people during normal times, but also for preventing the fall of those who escape in an emergency evacuation.

  On the other hand, the door 9 that opens and closes the opening 7 through a window glass (not shown) has substantially the same structure as the door 6 except for the carriage 56 and the groove 56a in the barrier-free structure. However, the door 9 may be provided on either the outside or the inside of the window glass.

  In addition, the building 4 includes a lighting fixture 41, water and food storage 42, a simple toilet 43, an air filter and an air purifier 44, a private power generator 45, a communication device 46, and the like as daily necessities. Yes. The specific arrangement is determined by the size of the room 4 and the size of each device. In addition, it is preferable to provide a periscope or the like that can look out of the building 4 even when the doors 6 and 9 are closed.

  FIG. 3 is a control block diagram around the door 6. For example, as shown in FIG. 3, the control system of the door 6 is centered on a personal computer (hereinafter referred to as a personal computer) 461 that is supplied with power from a private generator 45 through a battery 451. Includes an external communication device 46 having an antenna 462, an input unit 463 such as a keyboard and a mouse, a display unit 464 such as a liquid crystal screen, an alarm unit 465 such as an alarm, and a hydraulic pump 67. The driver 601 and the sensor 604 for detecting the open / closed state of the door body 60 of the door 6 are electrically connected to each other.

  The hydraulic pump 67 automatically expands and contracts the hydraulic cylinder 68 via the hydraulic circuit 602, but manual operation by the handle 603 provided near the door body 60 is superior to the expansion and contraction operation of the hydraulic cylinder 68. To do.

  Then, due to the expansion operation of the hydraulic cylinder 68, the seal packing 691 of the door body 60 is pressed against the seal packing 692 on the wall surface around the opening 5, whereby the opening 5 is sealed, and this sealed state is detected by the sensor 604. It is to be detected. Further, due to the reduction operation of the hydraulic cylinder 68, the seal packing 691 of the door body 60 is separated from the seal packing 692 on the wall surface around the opening 5. Then, the carriage 65 on which the door main body 60 is placed is automatically returned to the original position slightly separated from the opening 5 below by being guided by the groove portion 65a by its weight. As a result, the sealed state of the opening 5 is released, and this released state is further detected by the sensor 604.

  The schematic operation of the door will be described below with reference to FIG. Suddenly a major earthquake and tsunami warning occurred in a certain area, but there is no time to evacuate to high ground. When this tsunami warning is received by the communication device 46, a notification is made from the notification unit 465 of the personal computer 461, thereby evacuating people nearby. Then, the power source of the personal computer 461 is automatically switched. Specifically, the private power generator 45 in the building 4 is automatically started, the power supply from the external power supply supplied so far is cut off, and the power supply from the private power generator 45 via the battery 451 is performed. Will be made. At this time, the lighting fixture 41 is turned on to ensure indoor lighting, and the hydraulic pump 67 of the hydraulic circuit 602 is driven via the driver 601 in accordance with a command from the personal computer 461.

  Then, for example, the person who finally escaped into the building 4 grabs a handle (not shown) and moves the door body 60 to the right side in FIG. 3 so that the door body 60 covers the entire opening 5. When the person travels to the carriage 65 and places it on the carriage 65, the person operates the handle 603 in a predetermined direction. Then, since the hydraulic cylinder 68 is extended, the door main body 60 is guided along the groove 65 a while being placed on the carriage 65, so that it is guided toward the wall surface around the opening 5 with a slight upward inclination. As a result, the door body 60 is pressed against the wall surface around the opening 5 via both seal packings 691 and 692 of the seal portion 69 to be in a sealed state. This sealed state is, for example, an electromagnetic wave (not shown) in the hydraulic circuit 602. It is easily maintained by closing the valve. The door 9 is also in a sealed state, and this sealed state is easily maintained.

  Eventually, a tsunami will attack, but in the building 4, the doors 6 and 9 can prevent the tsunami and the tsunami from entering and exiting.

  After the tsunami passes, the surrounding area becomes mountains such as rubble and may become isolated for a while. Even in such a case, the lighting device 41 and the simple toilet 43 can be used, and water and food can be taken out from the storage 42 and ingested. In addition, air for breathing with the air filter or the air purifier 44 is secured, and the communication device 46 can request relief and can live comfortably in the building 4 until this rescue team comes.

  When the rescue team arrives, they will escape from the building 4. At this time, for example, a person evacuating in the building 4 operates the doors 6 and 9 easily by operating almost the reverse procedure. Can be opened. That is, after opening a solenoid valve (not shown) in the hydraulic circuit 602 and operating the handle 603 in the reverse direction as described above, the hydraulic cylinder 68 is reduced. Then, mainly due to the weight of the door main body 60, the door main body 60 remains on the carriage 65 and is guided to the opposite side of the upward slope in the groove 65 a, and automatically from the wall surface around the opening 5. To leave. As a result, both seal packings 691 and 692 of the seal portion 69 are separated from each other, so that the sealed state of the door body 60 is easily released. Thereafter, the person can hold the handle (not shown) and move the door body 60 to the left side in FIG. 2 to open the door body 60 and fully open the opening 5. Similarly, the door 9 can be fully opened.

  As described above, according to the doors 6 and 9 of this embodiment, the doors 5 and 7 can be opened and closed by running along the rails 61 and 62 provided above and below the openings 5 and 7. When the main body 60 and the door main body 60 are traveled to a position covering the whole of the openings 5 and 7, the door press capable of pressing the door main body 60 against the wall surfaces around the openings 5 and 7 through the seal portion 69. So that when a tsunami strikes, the openings 5 and 7 of the building 4 are sealed to prevent debris from flowing through the openings 5 and 7 and evacuate there. Although not touched on in this embodiment as well as human beings, when a building is a factory, a store, etc., it is possible to safely protect factory equipment, products, etc. until the influence of the tsunami is eliminated.

  In addition, in the said embodiment, the building 4 provided with the doors 6 and 9 has illustrated the reinforced concrete structure which consists of one floor and only one room, but it is two or more rooms and / or two or more floors. It may be a thing. In that case, it is good also as providing the doors 6 and 9 of each floor separately, and it is good also as a large door which integrated the doors 6 and 9 of several floors. In that case, it is preferable to provide a latent door in a part of the large door or to provide an emergency spiral staircase or the like in the room.

  Moreover, in the said embodiment, although the doors 6 and 9 are equipped with the flash-shaped door main body 60 which reinforced the iron plate from the back surface, this door main body 60 is the intensity | strength and operation required when a tsunami hits. The so-called honeycomb structure or the like may be used. The door body 60 is mainly closed manually, but may be automatically closed when the communication device 46 receives a tsunami warning. However, in this case, manual operation is given priority. Furthermore, instead of the hydraulic pump 67 and the hydraulic cylinder 68, other types of actuators such as a pneumatic cylinder and an electric motor may be used.

  Furthermore, when the doors 6 and 9 are small doors, all may be opened and closed manually. In that case, a person evacuated to the inside of the building 4 causes the door body 60 to travel along the rails 61 and 62 provided above and below the openings 5 and 7, so that the door body 60 is opened. Drive to the position that covers the whole. Next, a temporary handle (not shown) accommodated in the door main body 60 is attached to a predetermined position and manually operated, and the door main body 60 is drawn toward the inside of the building 4, whereby the door main body 60 is opened to the opening 5. , 7 to seal. Thereafter, the human can reverse the temporary handle to open the door body 60 and fully open the openings 5 and 7.

  Moreover, in the said embodiment, although the rail of the doors 6 and 9 is provided in the upper and lower sides of the opening parts 5 and 7, respectively, you may provide in the right and left. In that case, the door body 60 travels in the vertical direction. Furthermore, the doors 6 and 9 may be double-opened instead of single-opened. When the doors 6 and 9 are small doors, instead of the combination of the carriage 56 and the groove 56a in the door pressing mechanism, a plate material or an angle material that guides the door body 60 toward the openings 5 and 7 and the like. A simple structure in which only the above is provided may be employed. However, the doors 6 and 9 do not necessarily have the same structure. For example, the door pressing mechanism of the door 6 at the entrance / exit of the building 4 is a combination of the carriage 65 and the groove 65a. A simple structure may be used.

  Moreover, in the said embodiment, although both seal packing 691,692 which comprises the seal | sticker part 69 has the substantially same width | variety, they may have a mutually different width | variety depending on the case. Even in this case, the center axis in the width direction of the seal packings 691 and 692 at the time of pressing may be shifted from each other in the width direction. However, in order to ensure the contact between both seal packings 691 and 692, it is preferable to configure as in the above embodiment. Further, both seal packings 691 and 692 are not necessarily made of the same material, and any material can be used as long as necessary fire resistance and water resistance can be obtained by a combination of both seal packings 691 and 692. However, when there is no risk of fire, it is not always necessary to provide the seal portion 69 with fire resistance.
