JP6309248B2 - Remodeling method and tsunami evacuation facility using the former gas station - Google Patents

Description

  The present invention relates to a remodeling method for remodeling a gas station or other gas station in a region that is relatively close to the coast and without a hilly area, such as a hilly area, into a structure serving as a tsunami refuge facility, and a tsunami evacuation constructed by the remodeling method Regarding facilities.

  In the coastal area facing the sea side like the Great Tsunami associated with the Tohoku Pacific Ocean Earthquake, the occurrence of a major earthquake in the near future and the arrival of a major tsunami are statistically predicted. In the case of many people, whether there are hilly areas or public buildings near the place of residence, workplace, school, or even commuting to work or commuting routes that can sufficiently respond to such a predicted tsunami The fact is that there is no tsunami evacuation facility in such a long-time stay. Thus, an artificial tsunami evacuation facility as an emergency evacuation site when a tsunami arrives has been proposed so far (for example, JP-A-2006-83549).

  On the other hand, in addition to the increase in equipment maintenance costs accompanying the recent tightening of fuel storage tank regulations due to the revision of the Fire Service Law, the demand for gasoline has decreased due to reasons such as the departure of young people from automobiles and the rise of electric cars. There is an increasing current situation. Once a gas station is closed, it is difficult to resume due to the nature of its facilities, so there is no other way but to dismantle it completely or use only the building that is left as it is for another purpose.

JP 2006-83549 A

  However, the above-mentioned artificial tsunami evacuation facility, when newly installed, has to secure a site in a conspicuous and relatively crowded place, so it is difficult to find a site, and land acquisition and facility construction There is a problem in securing the budget. In addition, the completed evacuation facilities often do not blend into the cityscape, which causes problems in the cityscape. It is also possible to use existing buildings instead of building evacuation facilities, but the height of the tsunami evacuation facility must be at least 1.5 times the expected height of the tsunami. When it exceeds 3 m, there are many cases in which existing buildings cannot be used, and as a result, there is a problem that a new facility must be constructed.

On the other hand, the general structure of a gas station that is going out of business for the reasons described above has a fuel storage tank in the basement and is used for offices, maintenance rooms, service rooms, etc. on the ground. In addition, since there is a canopy part with a roof supported by props to avoid rain and direct sunlight from refueling equipment and refueling workers, it is difficult to change to a facility for other uses, However, even if the site is demolished, there is a problem that a large amount of expenses are required for the construction of the site, such as the construction of the ground canopy roof from the underground fuel storage tank.
In view of such circumstances, the present invention has been made for the purpose of simultaneously solving the problems of both sides.

  The means of claim 21 is that the evacuation means is a crossing passage connecting the evacuation floor surface and the building of the gas station site.

  According to the rebuilding method and the tsunami evacuation facility using the gas station site of this invention and the tsunami evacuation facility, the number of gas station sites that increase year by year can be effectively used, and a tsunami shelter can be constructed at low cost. . Gas stations such as gas stations were originally built along the road with lots of cars and traffic, so if you replace the high signboard of the gas station there with a signboard for the evacuation shelter, the local residents will stand out well. It is easy to get away even if the tsunami warning is suddenly issued and delayed. In particular, when the building in the site is remodeled into a facility for the weak, such as daycare or day care, evacuation guidance is easy and delays in evacuation can be prevented. In addition, by remodeling the facilities that can be used on a daily basis, the tsunami evacuation facility can be managed and operated at the same time. Furthermore, the cost for renovation is low.

And since the gas station itself is constructed to match the cityscape at the time of installation, the basic structure will not change even if remodeling is made, so the cityscape will not be damaged. Furthermore, since there are many gas stations in the tsunami inundation warning area along the coast, the use of the ruins is particularly effective. You don't have to worry about securing land like you do. Furthermore, since the pillars of the piloty part are strong so as to efficiently enter and exit the vehicle and support the roof by reducing the number of cars, it is easy to avoid the tsunami wave force and drifting objects. Further, since the roof is mostly a flat roof or a roof with a small slope, even if the roof surface is used as an evacuation floor surface of the evacuees as they are or improvements are made, the number of renovation steps can be reduced.

  Even if wave power or drifting object hits the column, it is safe because the roof is reinforced to withstand those loads even if a large number of people evacuate. Moreover, since the roof surface is used as the evacuation floor surface and the handrail is provided on a part or all of the periphery thereof, there is no risk of falling from the evacuation floor surface.

Furthermore, since an evacuation means for the evacuation floor surface is provided, it is possible to evacuate to the evacuation floor surface corresponding to the roof of the piloty part at a sufficiently high position from the ground.

If the evacuation means is a stairway that connects the ground of the refueling site and the evacuation floor, a person at the refueling site can easily evacuate. Also, if a plurality of staircases are installed in different directions, it is safe to use the staircase at a position opposite to the arrival direction of the tsunami.

If the evacuation means is a transit passage that connects the building at the gas station site and the evacuation floor, move from the stairs of the building to the upper floor and go from there to the evacuation floor through the passage. Therefore, it is not necessary to install stairs on the way, and because it moves from the building, it is a little safe even if the tsunami comes after being delayed. Furthermore, by communicating via the crossing passage, the evacuation floor can be held more firmly than in the case where the evacuation floor is supported only by the columns. Moreover, since people can evacuate to this passage, more people can evacuate.

Reinforcement of the canopy strut can be protected from tsunami wave pressure, wave force and drifting objects by using a lower reinforcing oblique column whose upper end is connected and fixed to the center of the strut and whose lower end is fixed to the ground. . In the case where a plurality of lower reinforcing oblique columns are used around the support column, it is possible to reinforce the number of tsunami directions as many as the lower reinforcing oblique columns are installed. In the case of a canopy that supports a single roof with multiple columns, it is possible to use lower reinforcing diagonal columns that face the same direction for each column, and to respond to tsunamis from all directions. The installation direction may be changed for each column. Further, the angle at which the lower reinforcing oblique column is attached to the support column is not particularly limited, but 45 ° is preferable in terms of strength.

In addition, the reinforcement of the column of the canopy part uses an upper reinforcing diagonal column whose lower end is connected and fixed to the center of the column and whose upper end is connected and fixed to the roof. The roof can be supported at as many points as the number of reinforced prisms, the support strength is improved, and so many people can evacuate to the evacuation floor. Here, when the upper reinforcement oblique column is provided in the extending direction of the lower reinforcement oblique column, the load from the evacuation floor can be received by the ground through the support column and the lower reinforcement oblique column. The load from the top is large and the reinforcing strength is improved.

Further, if the upper end of the upper reinforcing oblique column and the roof are connected and fixed via a reinforcing beam newly provided on the lower surface of the roof, the roof can be supported by a line rather than a point, so that a ramen effect can be obtained. In this case, it is more efficient to interpose the reinforcing beam in the longitudinal direction of the roof.

The greater the number of lower and upper reinforced oblique columns, the stronger the columns and the load on the roof can be supported. However, if they are installed at equal intervals around the columns, the load applied to the columns may be evenly distributed. It can be balanced and improve durability as a whole.

  When the canopy strut reinforcement is hung on a beam member that is supported on both sides of the roof by pillar members, the load is supported by the beam member even when a large number of people are placed on the evacuation floor. Since it can be received, the burden on the support can be reduced. The pillars can also be used to block the tsunami from wave pressure, wave power and drifting objects. The column member may also be provided at the center of the beam member. In the case of reinforcement of this column, since there is no column reinforced under the roof, the space under the roof can be effectively used as a place for daily activities. Note that, when it is desired to further strengthen the strength of the column, the space under the roof is sacrificed, but the column and the roof may be reinforced using the lower reinforcing oblique column and the upper reinforcing oblique column.

  If the column member is reinforced concrete, there is an advantage that the resistance against the tsunami wave force and the impact of the drifting object is increased. The beam member may be a steel structure because it only needs to support the load when the roof is suspended. . It would be more convenient if a storage room for storing emergency supplies such as food, medicines, cold protection tools, rescue signal transmitters, etc. was secured inside the steel structure.

  The reinforcement of the canopy support can be achieved even when a large number of evacuees are placed on the evacuation floor of the roof by using a support column with the lower end fixed to the ground around the support and the upper end connected to the roof. Can be supported. In addition, it is possible to prevent tsunami wave pressure, wave force and impact caused by direct collision of drifting objects on the support. If the upper end is connected and fixed at an orthogonal point of the grid, which is a component of the roof, it can be connected more reliably.

DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described below with reference to the drawings.
First, an example of an existing gas station (gas station) site before reconstruction by the reconstruction method of the present invention will be described with reference to FIGS.
The gas station A is facing the roadway and has a substantially quadrangular shape that is paved as a whole, and there is a building 4 with rooms such as an office 1, a repair bit 2, and a service yard 3 at the corner. A refueling device 5 is arranged at a predetermined distance on the front side of the building 4, and a canopy unit 6 is provided for preventing the refueling device 5 and the refueling worker from rain and direct sunlight. The canopy unit 6 is composed of a plurality of columns 6 fixed to the ground in the vicinity of the refueling device 5 and a roof 7 supported by the columns 6, and the roof 7 is surrounded by three refueling devices 5. The upper part and the upper part between the oil supply apparatus 5 and the front side of the building 4 are covered. Also, a fuel storage tank 9 is buried in the basement of the site between the building 4 and the refueling device 5 at the end. Further, an advertising tower 10, a waste oil tank 11, a fire extinguisher box 12, a fire pit 13 and the like are provided.

  For example, in order to rebuild this gas station A to a tsunami evacuation facility B shown in FIG. 3, for example, the tsunami wave pressure of the pillar 7 of the canopy section 6 among the above-mentioned facilities in the existing gas station A , Horizontal load against impacts such as wave force and drifting objects, reinforcement against load capacity of many evacuees, reconstruction of roof 8 to evacuation floor 14, handrail to all or part of evacuation floor 14 15, installation of stairs 16 or a passageway 17 as an evacuation means from the ground of the gas station A or from the building 4. Among these, there are three specific methods for reinforcing the canopy section 6, and the remodeling method and the equipment after the remodeling will be described sequentially with reference to the drawings, including other remodeling.

First, a first embodiment of a specific method for reinforcing the canopy portion 6 in FIGS. 3 to 7. In this embodiment, the layout of the building 4 is shown as a nursery. For example, the repair bit 2 is a childcare room 18 and a small room attached thereto, and the service yard 3 is a water storage tank or storage battery device. The emergency member room 19 is used, and the office room 1 is used for various purposes such as a lunch room 20, a play room, other office rooms, and staff changing rooms.

The support column 7 of the canopy unit 6 is reinforced by using a lower reinforcing oblique column 71 and an upper reinforcing oblique column 72. The lower reinforcing oblique column 71 has a lower end fixed to the ground and an upper end connected and fixed to the central portion of the column 7. The purpose is to maintain the column 7 in the vertical direction and to protect it from tsunami wave pressure, wave power and drifting objects. Although the inclination angle with respect to the support column 7 is not particularly limited, 45 ° is optimal. The fixing to the ground may be solidified with concrete in the ground, and the connection and fixing to the support column 7 is performed through bolts / nuts, welding, mounting brackets, etc., but these may be fixed by other means. . If the support column 7 is a quadrangular column, the number of attachments is suitably four at equal intervals of 90 °. If the support | pillar 7 is a cylinder, it is suitable to carry out via an attachment metal fitting, and the number is not limited to four pieces.

Similarly, the upper reinforcing oblique column 72 is connected and fixed at the lower end to the center portion of the column 7 and the upper end is connected to the roof 8, and the evacuation floor surface 14 provided on the roof 8 is similarly set with respect to the mounting angle and number. It receives the load of the refugee on the board and transmits it to the column 7. At this time, if the center line of the upper reinforcing oblique column 72 is positioned on the extension of the center line of the lower reinforcing oblique column 71, the load of the evacuees on the upper reinforcing oblique column 72 is applied to the lower reinforcing oblique column 71. As a result, the burden on the column 7 is further reduced. The connection between the upper end of the upper reinforcing oblique column 72 and the roof 8 may be directly connected and fixed to a structural member used for the roof 8, but it is reinforced on the lower surface of the roof 8 as shown in FIGS. 4 and 5. If the beam 21 is provided and the upper end of the upper reinforcing oblique column 72 is connected and fixed to the reinforcing beam 21, the roof surface, that is, the evacuation floor surface 14 is also reinforced. Further, a ramen effect can be obtained against a tsunami from the longitudinal direction of the reinforcing beam 21.

The strut 7, the lower reinforcing oblique column 71, and the upper reinforcing oblique column 72 may be members having the same cross-sectional structure or different members. When the support column 7 is a square member, the upper and lower reinforcing oblique columns 72 and 71 are connected and fixed to the center in the vertical direction of each surface of the support column 7 so that one set becomes an X shape with the support column 7 interposed therebetween. On the other hand, if another set is fixed at a right angle, it is 90 ° at equal intervals around the support column 7, which is preferable in terms of strength.

As shown in FIG. 3, two staircases 16 as evacuation means are preferably provided in two places on the building 4 side and the opposite side, and are prepared in case of an emergency. In addition to the staircase 16, as shown in FIG. 7, a crossing passage 17 for connecting and fixing the building 4 and the evacuation floor 14 may be provided. The crossing passage 17 also serves to connect and fix the roof 8 constituting the canopy portion 6 to the building 4. In addition, when this transfer passage 17 is long, people can stand on this road surface, and the number of evacuees can be increased. In addition, as a evacuation means other than such a structure, a rope, a rope ladder, or the like may be provided on the evacuation floor surface 14, and the stairs 16 or the passageway 17 may be damaged or may be an evacuation means for relief of a drifter.

  The evacuation floor surface 14 provided on the upper surface of the roof 8 can be used as it is without special remodeling because the roof 8 is a flat roof or a roof with a small gradient in many cases. Therefore, it is necessary to rebuild the roof surface in the horizontal direction so as to have a minimum gradient that does not cause anxiety to the evacuees. Further, even when the roof 8 is a flat roof, the weight may be reduced, and the roof 8 may be remodeled so as to easily balance the weight when many evacuees are placed. Further, it is safe to provide a slip stopper on the surface of the evacuation floor 14. Furthermore, it is desirable that the handrail 15 provided around the evacuation floor 14 is a solid one connected to the structure of the roof 8. Further, the stairs 16, the passageway 17, the handrail 15, the newly reconstructed evacuation floor 14 as the evacuation means, such as punching metal, lath wire mesh, mesh, grid-like fine metal wire with gaps, etc. Adopting a material that can withstand the weight but has many gaps is suitable for attenuating the wave pressure and wave force of the tsunami.

  In addition to the canopy section 6 and the building 4, the gas station A has facilities such as an underground fuel storage tank 9, an advertising tower 10, a fire pit 13, and the like, which can also be effectively used as a tsunami evacuation facility B. For example, the fuel storage tank 9 can be used for storage of fresh water, or for application to a device that generates a rescue signal by utilizing a buoyancy of a floating body that is stored inside the floating body and tsunami water enters. In addition, since the advertising tower 10 is originally raised so as to be visible toward the adjacent road, the evacuation facility is displayed on the advertising tower 10 so that the local residents can be informed and enlightened on a daily basis. This helps to prevent confusion during evacuation. The fire pit 13 can effectively prevent hot air and fire spread even if a nearby house becomes a fire, and can protect refugees on the evacuation floor 14.

  The building 4 can be remodeled in various ways by clarifying its purpose of use. The floor plan of the building 4 shown in FIG. 2 can be renovated to the day nursery shown in FIG. In this case, it is better to have a disaster prevention equipment room 19 for storing emergency materials such as water storage tanks and storage battery panels. In addition, the area below the evacuation floor 14 is a well-ventilated shade and can be used as a terrace or a playground for infants. If the building 4 is a facility for physically weak people such as a nursing home, a day care facility, a nursing facility, etc., it is easy to evacuate easily even if it is delayed.

  As shown in FIGS. 8 and 9, in the second embodiment of concrete reinforcement of the canopy portion 6, the roof 8 constituting the canopy portion 6 is hung on a beam member 23 supported at both ends by column members 22. It is a structure that has been. The column member 22 can withstand a tsunami wave pressure, wave force and drifting material, and can protect the column 7 with a strong structure such as a rebar concrete. The beam member 23 is made of steel and has a hollow portion 24, and both sides in the longitudinal direction of the roof 8 are suspended by suspension members 25 such as wires and bolts or directly connected and fixed to the roof 8, that is, on the evacuation floor surface 14. Even when a large number of evacuees are placed on the column 7, it is possible to prevent the column 7 from being loaded. The column member 22 may also be provided at the center of the beam member 23. Also, a plurality of beam members 23 may be provided in the short direction of the evacuation floor 14. Furthermore, the pillar member 22 and the beam member 23 may be formed in an arch shape made of a steel frame or the like, and the evacuation floor surface 14 may be hung by a rope or a reinforcing bar. In this case, there is an advantage that the surrounding landscape is improved. is there. The stairway 16 as the retracting means is suitable between the column members 22 at the end portions in the longitudinal direction, but may be other places. Further, the staircase 16 can be installed more firmly if the column member 22 is wound, and the possibility that the staircase 16 is destroyed due to tsunami, wave force, or the like is reduced.

  The hollow portion 24 of the beam member 23 is used as a hangar for emergency materials such as food, medicines, cold protection tools, rescue signal transmitters, etc., and serves as a handrail for evacuees on the evacuation floor 14. Furthermore, the same purpose as the advertising tower 10 can be given by displaying a shelter on the side facing outward. Furthermore, since there is no support member such as a pillar under the evacuation floor 14, a large space can be obtained and effective use can be achieved.

   As shown in FIG. 10, the third embodiment of the concrete reinforcement reconstruction method of the canopy portion 6 and the tsunami evacuation equipment B includes a plurality of lower ends fixed to the ground and upper ends connected to the roof, as shown in FIG. The support pillar 26 supports the roof 8, that is, the evacuation floor 14. The number of support pillars 26 is not specified because they are affected by the size of the diameter and the strength of the material. However, the support pillars 26 are provided around the support pillars 7 to protect the support pillars 7 from tsunami wave pressure, wave power and drifting objects. Therefore, it is desirable to arrange the load at a position where the load can be evenly supported in consideration of the expected arrival direction of the tsunami.

  The connecting and fixing of the support pillar 26 with the roof 8 can be more firmly fixed and stabilized if it is performed at the orthogonal point of the grid of the structure of the roof 8. In this case, the beam grid of the existing roof 8 is divided into, for example, a 1.4 m orthogonal grid, and support pillars 26 are arranged at all the intersections 27 from the evacuation floor 14 on which the refugees are placed. Distribute the load. Thereby, even if the diameter of the support pillar 26 is thin, a large number can be taken, so that the load can be endured.

The overall trial calculation when the reinforcement of the column 7 of the first to third embodiments is employed will be described. Since the height of the evacuation floor 14 needs to be 1.5 times the height of the assumed tsunami, when the height to the evacuation floor 14 of the canopy portion 6 is 6.0 m, The assumed tsunami height can withstand up to 4.0. Since the area of the evacuation floor 14 is about 300 m ² on the roof 8 of the canopy section 6 of a general gas station, it was estimated that a maximum of 600 people can be accommodated from this area, and the total load 36t was calculated therefrom. The column 7 is a metal column having a regular square cross section and a width of 400 mm, and the vertical reinforcing oblique columns 72 and 71 are the same. The connection fixing angle with respect to the column 7 and the roof 8 was 45 °. The lower reinforcing oblique column 71 was fixed to the ground with the lower end covered with concrete in the ground. The stairs 16 are provided at two locations facing the evacuation floor 14 and the ratio of height to tread is set to 1: 2 in consideration of use by infants and care recipients. Building 4 was used as a day-care center, and was renovated to place each room as shown in the figure.

  As is clear from the above explanation, according to the method of remodeling a tsunami evacuation facility using the gas station site of the present invention and the tsunami evacuation facility, the site of the gas station that has been abandoned and left untreated is converted into a tsunami evacuation facility. I can do it.

  This invention enables effective use of a gas station, such as a gas station, that has been closed down as a tsunami evacuation facility, so that the capital investment in public facilities in each local government, etc. And land rental income.
