Description

  This invention is used as a car parking lot during normal times, and when a large tsunami occurs due to a large earthquake, evacuates into the car parked in the parking lot, and the parking lot rises to the surface by the power of the water of the big tsunami This relates to the structure of a parking lot for evacuating large tsunamis for safe evacuation.

  The total of the dead and missing people who died due to the Great East Japan Earthquake that occurred on March 11, 2011 and the accompanying great tsunami reached more than 20,000 people. Large earthquakes such as the Tokai Trough Earthquake will continue in the future. It has been pointed out that there is a risk of a large tsunami, and it is indispensable to prepare measures for saving lives in the event of a disaster.

  In order to avoid encountering a tsunami disaster when a major earthquake occurs, it is necessary to evacuate to a safe high ground as soon as possible, but for people living near the epicenter or on coastal areas where there is no high ground There is no time to evacuate to high buildings, high grounds, etc., especially in the case of elderly people such as those with weak legs. It is very difficult to evacuate up to the high rooftop by going up the stairs, and when evacuating by car, it becomes difficult to move to the evacuation site due to traffic congestion etc. There was a high risk of death from being caught in a tsunami.

  Furthermore, in the Nankai Trough earthquake forecast shown last August, the death toll was estimated to be up to 320,000 people and the total destruction of the building was expected to be 2.38 million. A shelter building has also been proposed. However, there are still doubts about whether elderly people can climb stairs that are more than 10 meters high in a short time, and there is no guarantee that the height of the tsunami is within 10 meters or less. The stage has not been reached.

  In view of such a situation, a simple shelter capable of evacuating in a short time when a tsunami occurs is proposed in Patent Document 1, for example. This is a shelter that is integrally attached to the house and can be moved in and out of the house. The shelter that separates the shelter from the house and the shelter separated from the house are sealed when the tsunami strikes. And a shelter that floats on water when separated from the house.

  However, in Patent Document 1, if the entire house is swallowed by high waves, the shelter may be crushed by the house and cannot rise to the surface of the water, and the shelter itself rises with the water level maintained There was a possibility that it could not be done, and the shelter was swallowed by a large tsunami, and the evacuees could be injured by rolling over or overturning, so the problem remained as a life shelter for tsunami evacuation.

  Further, for example, in Patent Document 2, the roof portion of a building is formed by a shelter having a sealed space, and the shelter is arranged above the living portion, and the upper portion is formed in a roof shape, and the lower portion is formed in a substantially ship bottom shape. The shelter that can be sealed is a shelter in which the living part and the shelter are fixed and integrated via an attaching means.

  However, since Patent Document 2 is a shelter having a sealed space, there are problems in terms of daylighting and ventilation for use as a living space during normal times, and when a large tsunami rushes, the shelter is large. There was a risk of getting involved in the tsunami and causing the shelter to roll over and capsize.

  Furthermore, for example, Patent Document 3 proposes a technique for raising and lowering the evacuation tower by driving a hydraulic cylinder connected to a strut fixed in the ground. However, when a large tsunami that exceeds the height that can be raised and lowered is approaching It was insufficient as a countermeasure.

As a result, the garage can be evacuated safely without any risk of overturning or overturning.

Embodiment 1 of the present invention will be described below.
Embodiment 1 of the Invention

  1 to 8 show a first embodiment of the present invention.

  1 and 2, the buoyancy chamber 7 of the tsunami life-saving car shelter (seat belt fixing type) according to the present invention is surrounded by a steel plate around the base structure 8 constructed on the ground, and foamed polystyrene is fitted inside. The slope 16 is installed so that the car 1 can enter and leave the buoyancy chamber 7, the car 1 is parked on the parking floor steel plate 6 at the top of the buoyancy chamber 7, and is mounted on the driver seat and the passenger seat of the car 1. Take out the tongue plate (T-shaped bracket) of the seatbelt from the lower part of the driver's door and the passenger's seat door, attach the tongue plate (T-shaped bracket) to the mounting hardware (ring catch) 4, and The state in which the mounting hardware (ring catch) 4 is attached to the fixing bracket 5 attached to the parking lot floor steel plate 6 is shown from the front of the automobile 1 in FIG. 1 and in a three-dimensional view in FIG.

  Further, in the case of a general passenger car in which the engine is arranged at the front portion of the automobile 1, the ratio of the load applied to the front tire and the load of the automobile 1 applied to the rear tire is approximately 6: 4. When parking on the upper part of the parking floor steel plate 6, the vehicle weight applied to the buoyancy chamber front portion 13 and the buoyancy chamber rear portion 14 is different, and therefore the amount of the polystyrene foam 52 fitted into the buoyancy chamber 7 described in FIG. When the buoyancy chamber 7 floats on the water surface, the parking lot floor steel plate 6 on the upper surface of the buoyancy chamber 7 keeps a horizontal state with respect to the water surface by being fitted into the buoyancy chamber front portion 13 more than the buoyancy chamber rear portion 14. Thus, the risk of the buoyancy chamber 7 rolling over or overturning is reduced.

  3 to 5 show a slack of a webbing (strap) 2 wound around a retractor (belt winding device) 22 when an automobile is fixed to a parking lot with seat belts provided in a driver seat and a passenger seat. A webbing slack take-up device 21 is shown for allowing a person to take up a seat belt (approximately 60 to 80 centimeters depending on the car type, but approximately 60 to 80 centimeters) to make the seat belt free from slack.

  In FIG. 3, the tongue plate (T-shaped bracket) 3 attached to the front end of the seat belt in the vehicle is taken out of the vehicle, and the mounting hardware (ring catch) 4 is attached to the tongue plate (T-shaped bracket) 3. Furthermore, the state which attached the attachment metal fitting (ring catch) 4 to the fixed metal fitting 5 attached to the parking lot floor steel plate 6 is shown. Generally, in a three-point seat belt of an automobile, one end of a webbing (strap) 2 is fixed to a webbing (strap) attachment portion 23 of a car body below the seat, and the other end passes through a shoulder belt anchor 20. The webbing (strap) 2 between the webbing (strap) mounting portion 23 and the shoulder belt anchor 20 is attached to a tongue plate (T-shaped bracket). ) 3 is movably passed through a slit portion (not shown), and the tongue plate (T-shaped bracket) 3 is inserted into a buckle 25 fixed to the side of the seat 24, so that the webbing (strap) 2 can be A webbing that is attached to the chest and waist of the body and wound around a retractor (belt winding device) 22 so that it can expand and contract in an emergency. The grayed (strap) 2, locking retractor (belt take-up device) 22 are the chest and waist of the human 26 is configured to be pressed against the seat 24.

  In this way, when a person sits on the seat and puts on the seat belt, the webbing (strap) 2 is always fixed at a constant strength by the retractor (belt winding device) 22 so that there is no slack. In order to maintain the state of being wound on the tractor (belt winding device) 22, the retractor (belt winding device) 22 has a webbing (strap) 2 of about 60 to 80 cm in the case of a normal passenger car. The slack portion is wound up, and as in the present invention, the tongue plate (T-shaped bracket) 3 of the seat belt is attached to the mounting hardware (ring catch) 4 attached to the parking lot floor steel plate 6, and the automobile 1 is attached. When trying to fix to the parking lot floor steel plate 6, for example, when the parking lot is shaken by a large tsunami and the car slides, the retractor (belt winding device) 2 The webbing (strap) 2 wound around 60 to 80 cm is pulled and stretched, so it was impossible to fix the car 1 to the parking lot floor steel plate 6 with a seat belt. .

  Therefore, in the present invention, as shown in FIG. 3 to FIG. 5, the webbing wound around the retractor (belt winding device) 22 by operating the webbing slack winding device 21 by a person who gets on the vehicle. By winding the (strap) 2 and removing the slack of the webbing (strap) 2, the automobile 1 can be fixed to the parking lot floor steel plate 6. By the way, in the explanation of the strength of the seat belt posted on the website by the top seat belt manufacturer TAKATA, "The belt part of the seat belt is called webbing, and it is made up of about 300 polyester threads. The belt strength is increased by weaving so many threads and it can withstand a load of about 3 tons. ”

  FIG. 3 shows a seat belt attachment method according to the present invention and a position where the webbing slack winding device 21 is sandwiched between the webbing (strap) 2 of the seat belt. The webbing slack take-up device 21 can be easily operated with both hands by inserting the webbing (strap) 2 into the webbing slack take-up device 21 in the chest position without wearing the seat belt while the human 26 is seated on the seat 24. I can do it.

  In FIG. 4, the webbing slack winding device 21 is shown in a front view and a side view. The webbing slack take-up device 21 has a flat pedestal 37 in which a webbing insertion port 36 is opened vertically to take up the webbing (strap) 2 and a circular hand for holding the pedestal 37 with a hand 45. In order to wind the webbing (strap) 2 around the fixing portion 38 and the flat plate-like attachment plate 39 fixed perpendicularly to the pedestal 37, for example, a grip 42 attached to a cap of a fountain pen is also provided. A circular webbing entraining roller 40 attached with a reverse rotation prevention gear 41 formed with a gear that prevents reverse rotation at the circumferential portion is fixed to the shaft 35, and the reverse rotation prevention gear 41 is reversely rotated. In order to prevent this, the reverse rotation prevention stopper 32 formed in a triangular shape so that the front end portion is hooked on the reverse rotation prevention gear 41 is prevented by the spring 34. A rotation handle 43 for rotating the webbing winding roller 40 and the reverse rotation prevention gear 41 is attached to the shaft 35, and a reverse rotation prevention stopper 32 is attached to the reverse rotation prevention stopper 32. In order to release the connection with the reverse rotation prevention gear 41, a ring-shaped stopper release ring 33 is attached so that the reverse rotation prevention stopper 32 can be pulled with a finger.

  As shown in FIG. 4 b, the webbing slack winding device 21 configured as described above is inserted with the webbing (strap) 2 from the webbing insertion port 36 and wound around the webbing winding roller 40, and the rotary handle 43 is moved in the direction of arrow 31. By rotating, the grip 42 fixed to the webbing winding roller 40 rotates in the same manner, and the webbing (strap) 2 is wound around the webbing winding roller 40, and the retractor (belt winding device) described in FIG. Since the slack of the webbing (strap) 2 wound around the belt 22 is eliminated, it becomes possible to fix the automobile to the parking lot with a seat belt.

  FIG. 5 is a three-dimensional view of the webbing slack winding device 21 described with reference to FIG. By configuring the webbing slack winding device 21 in this way, it becomes possible to remove the slack of the webbing (strap) 2 of the seat belt, and in the case of an emergency evacuation during a large tsunami, a car can be parked with a simple operation. It is now possible to evacuate safely from a large tsunami by evacuating to the interior of a car.

  FIG. 6 shows the substructure 8 and the slope 16 and the buoyancy chamber 7 described in FIG. 2 in an exploded view. At the upper part of the foundation structure 8 constructed on the ground, pillars 55 formed by square steel pipes are arranged at the four corners, and the upper and lower portions of the side surfaces of the square steel pipes adjacent to the square steel pipes are formed by the upper and lower beams 53 and 56. Are welded to each other, and a flat beam is formed by welding a flat steel material to the lower beam 56 so that the bottom has a plane lattice shape, and a flat plate is formed on the outer side surfaces of the upper beam 53 and the lower beam 56. The steel plate 9 is welded and attached, and a rectangular polystyrene foam 52 is fitted inside the box-shaped box constructed as described above. Further, the upper beam 53 is provided with an H-section steel 51 for reinforcement at the lower part. The parking lot floor steel plate 6 to which is attached is attached.

The four poles 58 fixed so as to be integrated with the foundation structure 66 are set up vertically, and the poles 58 are loosely inserted into the upper part and the lower part of the column 67 of the garage 57 facing the four poles 58. The state which attached the pole guide metal fitting 59 which can be shown is shown in a three-dimensional view.

  The pole guide fittings 59 attached to the upper and lower portions of the column 67 of the garage 57 have a rectangular shape at the center so that a cylindrical pole 58 can be inserted as shown in the enlarged view of FIG. The guide box 62 is formed in a substantially rectangular parallelepiped shape with an opening and two rollers 60 and 63 attached so as to protrude inside the rectangular opening of the guide box 62. A mounting plate 61 for fixing the pole guide metal fitting 59 to the column 67 of the garage 57 is attached. By attaching the two rollers 60 and 63 to the guide box 62 in this way, even when a situation occurs in which one of the garages 67 is lifted by the large tsunami when the garage 57 is lifted by the large tsunami, the guide It is possible to prevent the box 62 and the pole 58 from rubbing and becoming engaged (fixed state), and the guide box 62 can move up and down smoothly with respect to the pole 58.

  FIG. 8 shows a state where the garage 57 described in FIG. 7 is lifted by a large tsunami, the buoyancy chamber 7 sinks below the water surface 68, and the garage 57 floats on the water surface 68 of the large tsunami together with the automobile 1. Thus, when the height of the tsunami is low (1 to 2 meters), the pole guide fitting 59 does not come off the pole 58 as shown in FIG. When the tsunami water height is higher than that of the pole 58, the pole guide fitting 59 is detached from the pole 58, and the parking lot is floated on the tsunami water. By configuring the pole guide bracket 59 and the pole 58 in this way, it becomes possible to evacuate safely no matter how high a large tsunami comes.

  When a major earthquake is encountered, the tongue plate (T-shaped bracket) 3 attached to the car 1 is quickly attached to the parking lot floor steel plate 6 with the mounting bracket (ring catch) 4 as described in FIG. As shown in FIG. 7, evacuates into the automobile 1 parked in the garage 57 as described in FIG. 7, and the slack of the seat belt webbing (strap) 2 described in FIGS. By winding with the slack winding device 21, the car 1 is fixed to the parking lot floor steel plate 6, and the first large tsunami rushes so that one end of the garage 57 is lifted, for example, when the ship gets over the large wave. In the case of falling into a state, the buoyancy of the buoyancy chamber 7 in which the foamed polystyrene 52 is fitted, the four vertically standing poles 58, and the garage facing each of the poles 58 The pole guide fitting 59 attached to the column 67 of the No. 7 floats on the water surface in a state where the garage 57 is maintained in a substantially horizontal state, and a large tsunami rises from the initial state of the large wave so that the water surface rises to the pole 58. The pole guide fitting 59 fixed to the column 67 of the garage 57 is disengaged from the four poles 58, and the garage 57 is floated on the surface of the large tsunami. In this way, by constructing a large tsunami levitation device for the garage 57 with the four poles 58 and the pole guide fitting 59, there is less risk that the garage 57 will smoothly float on the large tsunami and roll over or overturn. It was.

  In this way, the buoyancy chamber 7 in which the foamed polystyrene 52 is fitted is arranged at the lower part of the garage 57, and the buoyancy chamber 7 is surrounded by the steel plate 9, so that the garage 57 is being swept away by a large tsunami, Even when the buoyancy chamber 7 surrounded by a flat steel plate is partially damaged, the foamed styrene 52 hardly absorbs water, so that the garage 57 does not sink in the water. It became possible to evacuate safely.
