Description

The present invention relates to a tsunami evacuation tower used when an evacuee evacuates urgently when a tsunami warning is issued.

When a tsunami warning is issued, the evacuees need to evacuate immediately to the hills, but because the hills are far from the refuge area, the evacuation could not be completed by the arrival of the tsunami. Many lives were lost by the tsunami that hit the Great East Japan Earthquake on March 11, 2011. In particular, elderly people, people with physical disabilities, hospitalized patients, etc., were unable to evacuate quickly to high ground, resulting in many victims.

Conventionally, many evacuation towers have been installed in areas where tsunami attacks are expected to eliminate the victims of such tsunamis. Further, when retroactively searching for past patent documents related to an evacuation tower as an evacuation measure due to a tsunami, for example, in the following Patent Document 1, a pair of metal pillars are erected at corresponding positions across a road. A tsunami evacuation tower formed by providing a floor for use is disclosed.

Japanese Patent No. 4678535

The evacuation tower installed in an area where the tsunami attack is expected is equipped with a stairway for the evacuees to ascend to the evacuation floor, and the tsunami evacuation tower described in Patent Document 1 is also a road. A pair of metal pillars are erected at corresponding positions across the floor to provide a floor, but there are multiple stairs for the evacuees to ascend to the evacuation floor. A large drifting object such as a house, vehicle or fishing boat that collapsed due to the above crashed into the tower column or stairs and the evacuation tower collapsed or broke down, making the evacuated refugee a dangerous state again There was a problem of being depressed.

The present invention has been made to solve the above-mentioned problems, and is provided with at least a pair of round shapes for fixing an evacuation floor without an elevating staircase or an elevating ladder for an evacuee to ascend to the evacuation floor. By setting up a steel pipe column or a round concrete column, even if a large drifting object such as a house, vehicle or fishing boat collapsed by a tsunami crashes into the tower column or stairs, the column has a round cross section. Since the contact area is small, the contact pressure of the drifting object is also weak, so that the evacuation tower is intended to provide a tsunami evacuation tower that does not collapse or break.

The present invention provides at least a pair of round steel pipe struts having a space of at least 8 m on the ground and having a height equal to or higher than the expected tsunami height, or round concrete, without an elevating staircase or a lifting ladder. A stanchion is erected and the evacuee's evacuation floor is suspended and fixed to the upper end of the stanchion, and a handrail for preventing fall is erected on the four peripheral edges of the evacuation floor, and the floor Attach a ridge plate with a solar panel above the surface, and install a storage battery for storing electrical energy generated by the solar panel on the floor, and with the electrical energy from the storage battery, A hoisting machine installed on the floor surface is operated so that a lifting rod suspended from the tip of the arm protruding forward on the roof plate can be moved up and down along the side surface of the column, and Tsunami warning A control device is provided on the floor for receiving a command signal by radio from the administrative office at the time of order, and a remote controller for operating the control device by radio is installed on the lift and a tsunami warning is provided. The above problem was solved by adopting a configuration in which the lifting rod is folded and stored in a bag and is suspended in contact with the tip of the arm except when issued.

The tower for tsunami evacuation according to the present invention having the above-mentioned structure is not provided with the elevating stairs and ladders as provided in the conventional tsunami evacuation tower on each column, so houses, vehicles, fishing boats, etc. collapsed by the tsunami The large flots of the crashed into the tower's pillars and stairs and the evacuation tower collapsed or broke down, causing the evacuated refugees to fall into a dangerous state again. The tsunami evacuation tower according to the present invention is not equipped with any lifting means such as elevating stairs and elevating ladders that protrude to the outside of the column as described above, so that anyone can climb except for the tsunami warning issued. No accidents such as people climbing and falling will occur, and there will be no mischief. Furthermore, if the tsunami evacuation tower of the present invention is installed at a corresponding position across the road, there is an excellent effect that the refugee can easily reach the tower through the road without obstructing traffic.

It is a front view at the time of non-use of this invention tsunami evacuation tower. It is a top view which notches and shows a part of this invention tsunami evacuation tower. It is a front view which shows a state when the 1st refugee is ascending to this invention tsunami evacuation tower at the time of tsunami warning issuing. It is a front view which shows a state when the second and subsequent refugees are ascending to the tsunami evacuation tower of the present invention when a tsunami warning is issued.

The tsunami evacuation tower according to the present invention has an interval of at least about a road width (8 m) on the ground such as a corresponding position across a road or a place where evacuation is easy, for example, without an elevating staircase or an elevating ladder. And, while standing at least a pair of round steel pipe struts having a height equal to or higher than the expected tsunami height, or a round concrete strut, and fixing an evacuee's evacuation floor to the upper end of the strut, A handrail for preventing fall is erected on the four peripheral edges of the floor for evacuation, and a ridge plate fitted with a solar panel is attached above the floor, and the sun is placed on the floor. While a storage battery is installed to store the electrical energy generated in-house by the light panel, an elevating rod that moves up and down along the side of the column with the electrical energy from the storage battery is installed. Command signal It is formed by providing a control device for lowering the lift cage by. Hereinafter, although it demonstrates in detail based on drawing, the said ground is demonstrated as a road for convenience of explanation, and the said support | pillar is demonstrated as a round-shaped steel pipe support | pillar.

As shown in the figure, a pair of round steel pipe struts 1 having a height equal to or higher than the expected tsunami height and having a width of about 2 lanes (8 m) across the road (ground) 2 Stand up against each other. The support column 1 is required to be erected on the ground 2 without being collapsed or broken even if it receives tsunami energy. Therefore, as shown in the drawing, the lower part of the support column 1 is buried and fixed in the ground 2 to stand firmly. In addition, the support | pillar 1 in this invention is not equipped with the raising / lowering means which protrudes outside the support | pillar 1 like the raising / lowering staircase and the raising / lowering ladder currently installed in the tower for tsunami evacuation. This is a major feature of the present tsunami evacuation tower. As described above, the tower for tsunami evacuation according to the present invention is not provided with any lifting means that protrudes to the outside of the column 1, so that no one can climb except when a tsunami warning is issued. There will be no accidents and no mischief.

In the present invention, the shape of the support column 1 is limited to a round cross section, and the interval between the support columns 1 is at least as wide as the road width (2 lanes, 8 m). Because the drifting house such as a collapsed house, a vehicle, or a fishing boat that is drifting passes between the columns 1, and even if the drifting material fought against the column 1, the column 1 is round. This is because the contact area with the drifting object is small, so that the drifting object is caught between the pillars 1 and the weights 1 prevent the pillars 1 from collapsing or breaking.

At the upper end of each column 1 erected on the road (ground) 2, a floor surface 3 on which the evacuated refugee waits until the danger of tsunami leaves is fixed to the support. The method for fixing the floor surface 3 is not particularly limited, but preferably, as shown in FIG. 2, the steel plate 5 is fixed to a rectangular frame-shaped fixed frame 4 supported on each of the columns 1. Is recommended. In addition, handrails 6 are installed at the four peripheral edges of the floor surface 3 so that the evacuees do not fall. In order for the evacuee who has boarded to move on the floor surface 3, the handrail 6 a on both ends is formed to be openable / closable / latching when the lifting / lowering rod 10 is installed on both the columns 1. As shown in the figure, when the lifting / lowering rod 10 is installed only on the support column 1 on one side, the handrail 6a only on one side is formed to be openable / closable and latchable. Furthermore, in the figure, a pair of support columns 1 are installed, but a plurality of pairs of support columns 1 can be installed according to the installation location to increase the area of the floor surface 2.

A roof plate 8 fitted with a solar panel 7 is installed above the floor surface 3, and a storage battery that stores electric energy generated by the solar panel 7 on the floor surface 3 is stored on the floor surface 3. 9 is installed.

Further, an elevating rod 10 that moves up and down along at least the outer peripheral wall surface of the support column 1 is installed (in the figure, it is installed only on the support column 1 on one side). The elevating rod 10 is formed on the floor 3 so as to be raised and lowered by a hoisting machine 11 that operates by receiving electric energy from the storage battery 9. That is, a hoisting machine 11 such as a winch installed on the floor surface 3 is connected to a base end portion of an arm 12 projecting forward from above the roof plate 8, and a wire 13 of the hoisting machine 11 is connected. However, an elevating rod 10 that extends downward through the pulley 14 at the tip of the arm 12 and that lifts the evacuee to the floor 3 is connected to the tip of the wire 13. The lifting rod 10 is preferably formed of a net so that it can be folded.

As described above, the tower for tsunami evacuation according to the present invention does not include an elevating staircase or an elevating ladder, and the only elevating means is the elevating rod 10. In the present invention, a control device 15 that controls the raising and lowering of the lifting rod 10 is connected to the storage battery 9 and installed on the floor surface 3. The control device 15 is wirelessly connected to a city, ward, town, village office, or administrative office such as a police station or a fire department, and simultaneously with the issuing of a tsunami warning, the control device 15 is activated to activate the arm 12. A command signal by radio is issued from the administrative office so as to lower the lifting rod 10 folded and hooked at the tip, thereby reversing the hoisting machine 11 and lowering the lifting rod 10 to the ground. It is configured to squeeze. A remote controller 16 having an up / down / stop push button switch connected to the control device 15 by radio is attached to the elevator rod 10. In the figure, reference numeral 17 denotes an antenna attached to the control device 15, which receives a command signal by radio from the administrative agency and receives a command signal from the remote control 16 attached to the elevator 10. Further, in the figure, reference numeral 18 denotes a bottom plate attached to the lifting / lowering rod 10 and is arranged on the floor surface 3 until a tsunami warning is issued.

The operation of the present tsunami evacuation tower configured as described above will be described. Before the tsunami warning is issued, as shown in FIG. 1, the lifting rod 10 is folded at the tip of the arm 12, stored in a bag 19 or the like and hooked at the tip of the arm 12, and the bottom plate 18 is disposed on the floor 3. When the tsunami warning is issued, the administrative office issues a command signal wirelessly to the control device 15 installed in the tower, depending on the scale of the tsunami, and reversely rotates the hoisting machine 11 until the arm until now. 12 The elevator rod 10 that is hooked at the tip is lowered onto the ground, the first evacuee takes out the elevator rod 10 from the bag 19 that wrapped the elevator rod 10, and the first evacuee Complete the preparatory stage to be able to ride.

Then, the first evacuee gets into the elevator rod 10 and pushes the lift button with the remote controller 16 installed in the elevator rod 10 to raise the elevator rod 10 to the floor 3. The first evacuees who got down on the floor surface 3 set the bottom plate 18 arranged on the floor surface 3 to the lift 10 so that the second and subsequent evacuees can easily get on and off. Thereafter, the control device 15 is manually operated to lower the elevating rod 10 onto the ground, and the second refugee is evacuated onto the floor surface 3. Thereafter, the same operation is repeated to evacuate the evacuees onto the safe floor 3.

After the evacuation cancellation notification for the tsunami, the control device 15 is operated in the reverse direction so far, and the evacuees are lowered in order from the floor surface. After removing the bottom plate 18 attached to the floor 3 and returning it to the floor surface 3, the user gets on the lifting rod 10 and operates the remote controller 16 to get down to the ground. The last evacuee who has landed on the ground folds the elevating basket 10 small and stores it in the bag 19. Thereafter, the administrative agency wirelessly issues a command signal to the control device 15 installed in the tower, rotates the hoisting machine 11 in the forward direction, and raises the lifting / lowering rod 10 stored in the bag to The operation of the evacuation tower is completed by stopping the operation of the control device 15 by wirelessly issuing a command signal by hooking it to the tip and finally sending a command signal. In addition, by folding the lifting / lowering rod 10 in a small size and storing it in a heat / cold and water resistant bag 19, it is possible to withstand changes in weather and there is no risk of falling even if strong winds blow.
