Description

[Technical field]

[0001] The present invention relates to exterior structures. [Background technology]

[0002] A technology has been proposed for supplying power from an electric vehicle or hybrid vehicle to a building using an on-board battery and a charging / discharging device installed in the vehicle (see Patent Document 1). With this technology, power can be supplied from the on-board battery to necessary electrical devices and electrical equipment in a building, so that an emergency power source can be secured and life in the building can continue even during a power outage, for example.

[0003] There is also known technology for installing charging equipment on a premises that supplies power to electric vehicles and plug-in hybrid vehicles (see, for example, Patent Document 2). This charging equipment is located outside the flow of people and vehicles on the premises, ahead of the direction of travel of the vehicle when parked, and adjacent to the vehicle's power receiving port. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-158309 A [Patent Document 2] JP 2014-30306 A Summary of the Invention [Problem to be solved by the invention]

[0005] For example, when a power outage occurs due to a natural disaster or the like, depending on the state of power restoration, people may have to live with the power outage lasting for several days, or with intermittent power outages due to rolling blackouts. However, even if such a power outage continues, if the technology described in Patent Document 1 is introduced, emergency power can be secured, so life in the building can continue. However, if the disaster involves flooding, if the car is submerged, it becomes impossible to supply power from the on-board battery to the building. Also, charging and discharging devices may not function if they are submerged. Therefore, there has been a demand for securing emergency power in the event of a disaster involving flooding by surrounding the site, including the parking space, with a water-stopping wall. Furthermore, if a vehicle is outside the site when a flooding disaster occurs, the vehicle may be hastily parked in a parking space, but if a charging / discharging device is placed ahead of the vehicle in the direction of travel when parking, as in Patent Document 2, it is possible that the vehicle may come into contact with the charging / discharging device. If the vehicle makes strong contact with the device, the charging / discharging device may no longer function, so even if the vehicle is hastily parked in a parking space, it is necessary to prevent the vehicle from coming into contact with the charging / discharging device.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to prevent a vehicle from coming into contact with a charging / discharging device when parking in a parking space, and to ensure an emergency power source in the event of a disaster involving flooding. [Means for solving the problem]

[0007] The invention described in claim 1, as shown in, for example, Figs. 1 to 6, is provided on a site 1 (first site 1A) including a parking space 5 for a battery-equipped automobile 9, with an entrance En on the front side of the site 1 for people and the automobile 9 to pass through, and a water blocking wall 10 constructed to avoid the entrance En; The site 1 includes a first site 1A surrounded by the water blocking wall 10 and including the parking space, and a second site 1B adjacent to the first site 1A and located outside the water blocking wall 10, and the entrance En is located on the boundary between the first site 1A and the second site 1B, The gate sleeves 11 located on both sides of the entrance En of the water blocking wall 10 include a front wall portion 11a along the outer periphery of the first site 1, A charging / discharging device 8 connected to the battery of the automobile 9 is installed at a position closer to the first site 1A than the front wall 11a in one of the gate sleeves 11 located on both sides of the entrance En, The first site 1A is elevated so as to be positioned higher than the ground level outside the second site 1B, and the second site 1B slopes downward from the end on the first site 1A side to the end opposite the first site 1A, and further, there are no steps on the ground from the inside to the outside of the site 1 on either side of the entrance / exit En.

[0008] According to the invention described in claim 1, it is possible to prevent water from entering the site 1 (first site 1A) in the event of a disaster involving flooding. This makes it possible to prevent the automobile 9 and the charging / discharging device 8 parked in the parking space 5 on the site 1 from being submerged, thereby ensuring an emergency power source in the event of a disaster involving flooding. In other words, the automobile 9 can be considered as part of the infrastructure (electricity infrastructure) and can be used in an emergency. Furthermore, the charging / discharging device 8 connected to the battery of the automobile 9 is installed at a position closer to the first site 1A than the front wall 11a of one of the gate sleeves 11 located on both sides of the entrance En, so that the charging / discharging device 8 is hidden behind the front wall 11a. Therefore, when the automobile 9 passes through the entrance En and proceeds toward the parking space 5, it can be reliably prevented from coming into contact with the charging / discharging device 8, which contributes to ensuring an emergency power source in the event of a disaster involving flooding. In addition, since the first site 1A is raised, the ground level at the first site 1A can be set higher than the ground level outside the second site 1B, making it difficult for flooding to occur. In addition, since the second site 1B is inclined downward from the end on the first site 1A side to the end on the opposite side to the first site 1A, even if the first site 1A is raised by filling the ground, no difference in level is created between the first site 1A and the second site 1B, and the passage of pedestrians and automobiles 9 is not impeded.

[0009] The invention described in claim 2 is, for example, as shown in Figs. 1 to 6, in the exterior structure described in claim 1, The gate sleeves 11 located on both sides of the entrance En are formed in a substantially L-shape in a plan view, and include the front wall portion 11a and a side wall portion 11b arranged perpendicular to the front wall portion 11a and extending toward the inside of the first site 1A. The charging / discharging device 8 is characterized in that it is installed on the side wall portion 11b of one of the gate sleeve portions 11 located on both sides of the entrance / exit En, on the opposite side of the entrance / exit En.

[0010] According to the invention described in claim 2, the charging / discharging device 8 connected to the battery of the automobile 9 is installed on the side wall 11b of one of the gate sleeves 11 located on both sides of the entrance En, on the opposite side of the entrance En, so that the charging / discharging device 8 is hidden behind the side wall 11b when viewed from the entrance En side. Therefore, the automobile 9 can reliably avoid coming into contact with the charging / discharging device 8 when passing through the entrance En and proceeding toward the parking space 5, which contributes to ensuring an emergency power source in the event of a disaster involving flooding.

[0011] The invention described in claim 3 is, for example, as shown in Figs. 1 to 5, in the exterior structure described in claim 1 or 2, A removable water stop plate 12 is provided between the front wall portions 11a of the gate sleeve portions 11 located on both sides of the entrance En.

[0012] According to the invention described in claim 3, a water stop plate 12 that is configured to be freely attached and detached is installed across the front wall portions 11a of the gate sleeve portions 11 located on both sides of the entrance / exit En, so that the entrance / exit En can be blocked by the water stop plate 12, thereby preventing water from entering the site 1 (first site 1A) in the event of a disaster involving flooding. Effect of the Invention

[0013] According to the present invention, it is possible to prevent a car from coming into contact with a charging / discharging device when parking in a parking space, and it is also possible to ensure an emergency power source in the event of a disaster involving flooding.

[Figure 6] 1A and 1B show an installation form of a charge / discharge device, in which FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the embodiment described below is subject to various limitations that are technically preferable for implementing the present invention, but the technical scope of the present invention is not limited to the following embodiment and illustrated examples. Note that the directions in the following embodiment and illustrated examples are set solely for the convenience of explanation.

[0016] In Fig. 1, reference numeral 1 indicates a site which is a residential lot. The site 1 is composed of a first site 1A on which a house 2 is built, and a second site 1B which faces a road not shown and is used as a parking lot. The first site 1A and the second site 1B are arranged adjacent to each other, and in this embodiment, the second site 1B is located on the south side of the first site 1A.

[0017] On the periphery of the first site 1A, there is an entrance / exit En at the front of the site (south side of the first site 1A) for people and automobiles 9 to pass through, and a watertight wall 10 constructed to avoid the entrance / exit En and surround the first site 1A. The entrance En is provided for passing between the first site 1A and the second site 1B, and is located on the boundary between the first site 1A and the second site 1B. In this embodiment, since the house 2 is located closer to the west side, the entrance En is located closer to the east side of the boundary between the first site 1A and the second site 1B. The width of the entrance En is set to a size that can accommodate the overall width of a car as stipulated by the Road Transport Vehicle Law. In addition, there are no steps on the ground between the first site 1A and the second site 1B on either side of the entrance En.

[0018] In addition, the water blocking wall 10 surrounds the first site 1A and, excluding the entrance / exit En, is provided between the first site 1A and the second site 1B located on the south side, and between the first site 1A and the neighboring sites on the north, east, and west sides. Such a first site 1A is raised by filling the land, and the ground level can be set higher than the ground level outside the site 1 (the road not shown, and the neighboring land on the north, east, and west sides). By raising the first site 1A, the house 2 built on the first site 1A also becomes taller, but in that case, the north side of the house 2 is constructed with a lowering design to comply with the north side slope restriction.

[0019] In the second site 1B, a plurality of rectangular floor materials 20 are arranged in parallel in an area used as a parking lot. The plurality of floor materials 20 are made of concrete poured into the ground. In addition, the second site 1B is inclined downward from the end on the first site 1A side (northern end) to the end on the opposite side to the first site 1A (southern end). In other words, the second site 1B is inclined downward from the boundary with the first site 1A to the end on the road side (not shown). In this way, the second site 1B is inclined downward from the boundary with the first site 1A, so that no step is created between the second site 1B and the first site 1A (entrance / exit En).

[0020] To explain the exterior of the first site 1A in more detail, the outside of the entrance door 3a at the entrance 3 of the house 2 is the entrance porch 4. The height position of the floor surface of the entrance porch 4 is set higher than the ground level of the first site 1A, and is set at approximately the same height as the dirt floor surface of the entrance 3. On the east side of the entrance porch 4, a parking space 5 where a car 9 can be parked is provided. On the west side of the entrance porch 4, there is a communication porch 6 which is formed integrally with the entrance porch 4 and has a continuous floor, serving as an outdoor living space.

[0021] Parking space 5 has multiple rows of rectangular floor materials 5a arranged in parallel in an area where automobiles 9 are parked. Each row of floor materials 5a is made of multiple stones embedded in the ground. The length dimension (dimension in the east-west direction) of each row of floor materials 5a is set longer than the width of automobiles 9. In other words, the area of ​​parking space 5 is defined by the multiple rows of floor materials 5a. In addition, parking space 5 is provided at ground level of first site 1A, and is therefore located below the floor surface of entrance porch 4. Furthermore, this parking space 5 is located adjacent to the entrance / exit En, and the floor material 5a (stone) is laid not only in the area where the automobile 9 is parked, but also in the area of ​​the entrance / exit En and the area on the entrance / exit En side of the second site 1B.

[0022] The automobile 9 parked in the parking space 5 is an automobile that runs on electric energy, such as a plug-in hybrid vehicle (PHV) equipped with a battery or an electric vehicle (EV). When charging at home, a charging / discharging device 8 is required. In addition, automobile 9 has a connection port for receiving power to be charged from charging / discharging device 8 and for transmitting power from the battery to charging / discharging device 8. The location of this charging / discharging connection port may differ depending on the vehicle model, and it is provided at the front end of the vehicle body, the front side of the side, the rear side of the side, etc., but it is usually provided at either the front end or the rear end of the vehicle body. Although not shown, the charging / discharging device 8 is equipped with a charging / discharging control unit that performs discharging control to output battery power to the outside of the automobile 9 and charging control to input power from the outside of the automobile 9 to the battery, and a connection cable with a plug that connects the charging / discharging device 8 to the connection port of the automobile 9.

[0023] Here, the outside of the automobile 9 refers to the power system of the power management system constructed in the house 2, and the power management system includes a distribution board having a power management control function and a power storage unit. The distribution board is connected to an external power transmission network, a power generation device in the building, and a power sales system in addition to the storage battery and the charge / discharge device 8. A representative example of the power generation device is a solar cell. The storage battery is configured to be able to store power supplied from the external power transmission network or the power generation device via the distribution board, and to store power from the battery of the automobile 9. The power stored in the storage battery is configured to be consumed within the house 2 and to be supplied to the external power sales system and the charge / discharge device 8 via the distribution board. Since the charging / discharging device 8 is incorporated into a power management system established in the house 2, the charging / discharging can be appropriately managed, thereby contributing to reducing the power costs in the house 2.

[0024] In this embodiment, various plants including trees 7 of various heights, flowers, grass, and the like are planted on both the first site 1A and the second site 1B. As the trees 7, trees with heights classified into small shrubs (up to 1 m), shrubs (1 to 3 m), and tall trees (3 to 10 m) are preferably planted.

[0025] Next, the water blocking wall 10 will be described in more detail. 1 to 3, the water blocking wall 10 is composed of gate sleeves 11 located on both sides of the entrance En, and a peripheral wall portion 13 formed integrally with the gate sleeves 11 and surrounding the first site 1A together with the gate sleeves 11. In other words, the entrance En is a gate in the first site 1A, and is formed between the gate sleeve 11 on the east side and the gate sleeve 11 on the west side.

[0026] The gate sleeve 11 is formed in an approximately L-shape in a plan view, and has a front wall 11a that follows the outer periphery of the first site 1A, and a side wall 11b that is arranged perpendicular to the front wall 11a and extends into the inside of the first site 1A. In both the east and west side gate sleeves 11, the side wall 11b extends from the end of the front wall 11a on the side of the entrance En into the first site 1A. Therefore, as shown in Figure 3, when the gate sleeve 11 is viewed from directly in front, the side wall 11b is hidden by the front wall 11a. In addition, a gate light and a mailbox are provided on the front wall portion 11a of the western side gate portion 11.

[0027] A water stop 12 is provided between the outer surface (south surface) of the front wall 11a of the east side gate sleeve 11 and the outer surface (south surface) of the front wall 11a of the west side gate sleeve 11. To explain in more detail, columnar supports 12a are erected in front of the outer surface (south surface) of the front wall 11a in the eastern gate sleeve 11 and the outer surface (south surface) of the front wall 11a in the western gate sleeve 11, and a sealing material is provided between these supports 12a and the front wall 11a to make it watertight. The waterstop 12 is supported by these support parts 12a. Sealing materials are provided at both ends of the waterstop 12, and when the waterstop 12 is supported by the support parts 12a, the gap between the support parts 12a is watertight. Sealing materials are also provided at the lower end of the waterstop 12, and when the waterstop 12 is supported by the support parts 12a, the gap between the support parts 12a and the ground (floor material 5a) of the second site 1B is watertight. The sealing materials provided at the lower end of the waterstop 12 are pressed against the ground (floor material 5a) of the second site 1B by the weight of the waterstop 12. In addition, in the event of a disaster involving flooding, the sealing materials provided at both ends of the waterstop 12 are pressed against the support parts 12a by water pressure from the outside.

[0028] The water stop plate 12 is usually stored in a storage space such as a shed with the support parts 12a on both sides detached, and is taken out of the storage space and fixed to the support parts 12a on both sides only in the event of a disaster involving flooding. That is, the waterstop 12 is configured to be detachable from the front wall 11a of the east side gate sleeve 11 and the front wall 11a of the west side gate sleeve 11. To explain in more detail, fixing means for fixing the waterstop 12 to the support parts 12a on both sides are provided between both widthwise ends of the upper end of the waterstop 12 and the support parts 12a on both sides. The fixing means are not normally used, but are used only in the event of a disaster involving flooding, and this allows the waterstop 12 to be detachable from the support parts 12a on both sides. The fixing means is suitably a latch device or a bolt, for example, but is not limited to these, and any means capable of preventing the water stop 12 from moving in the event of a disaster involving flooding is sufficient.

[0029] The peripheral wall 13 is constructed by having the foundation buried in the ground and concrete blocks piled up on the foundation. The peripheral wall 13 is integrally formed with the gate sleeve 11, but is set at a lower height than the gate sleeve 11. In this embodiment, the height of the peripheral wall 13 is set to about half the height of the gate sleeve 11. Therefore, the view from the house 2 to the outside of the site 1 is excellent. In this embodiment, the height dimension from the height position of the road (not shown) to the height position of the upper end of the peripheral wall 13 is set to 1 meter. On the other hand, the height dimension from the ground of the first site 1A to the height position of the upper end of the peripheral wall 13 is set to 60 centimeters. In addition, the height of the peripheral wall 13 is set to be approximately equal to the height of the waterstop 12 when fixed to the support parts 12a on both sides. In other words, even if the height of the waterstop 12 is made higher than the height of the peripheral wall 13, it is not possible to prevent water from entering the waterstop 12 up to the height of the peripheral wall 13. Therefore, the height of the waterstop 12 does not need to be higher than necessary, and is set to be approximately equal to the height of the peripheral wall 13. In this embodiment, all of the peripheral wall portions 13 are set to the same height, but at least the portion 13a located in front of the front part of the house 2 may be set to a height lower than the gate sleeve portion 11.

[0030] Furthermore, a mesh-like greening fence 14 onto which plants can become entangled is attached on the inside site side (the side facing the first site 1A) and outside site side (the side facing the second site 1B) of the front site portion 13a of the peripheral wall portion 13, which is located at least in the same direction as the gate sleeve portion 11 (the south side in this embodiment), as shown in Figures 1 to 5. The greening fence 14 is composed of multiple metal wires arranged in the vertical and horizontal directions, and as shown in Figures 4 and 5, the wires arranged in the vertical direction are formed in a zigzag pattern with portions fixed to the side of the peripheral wall portion 13 and portions protruding outward from the side of the peripheral wall portion 13. In addition, the multiple wires arranged in the left-right direction are bridged between the portions of the multiple zigzag wires arranged in the up-down direction that are located closest to the peripheral wall portion 13, and also bridged between the portions that protrude most outward.

[0031] The lower end of the greening fence 14 is buried in the ground, and the upper end is located below a coping 15 provided at the upper end of the peripheral wall portion 13. The end of the coping 15 on the first site 1A side and the end on the second site 1B side are formed to protrude downward so as to hide the upper end of the greening fence 14. Plants entangled in the greening fence 14 spread along the multiple metal wires arranged in the vertical and horizontal directions, but are unlikely to grow upward beyond the end of the coping 15 on the first site 1A side and the end on the second site 1B side. In other words, plants entangled in the greening fence 14 spread and grow within the range of the greening fence 14, and are prevented from growing excessively upward.

[0032] Because it is located in front of the house 2 and the communication porch 6, the greening fence 14 is preferably installed on the inside and outside sides of the site at the front side of the site in the part 13a of the peripheral wall 13, but it may be installed in other parts of the peripheral wall 13 or on the gate sleeve 11.

[0033] 1 and 6, the charging / discharging device 8 is provided on the side wall 11b of the east side gate sleeve 11 of the water blocking wall 10 configured as above, on the opposite side from the entrance En. In other words, when viewed from the entrance En side, the charging / discharging device 8 is hidden by the side wall 11b. The charging / discharging device 8 in this embodiment is configured by providing a main body 8a formed in a prismatic column shape and set at a height substantially equal to that of the side wall 11b with a cable connection section 8b to which the plug-equipped connection cable is connected, a charging / discharging operation panel 8c, and an outdoor outlet box 8d. The cable connection section 8b and the charging / discharging operation panel 8c (for operating charging / discharging on / off, etc.) are provided on the east side of the main body 8a, but may be provided on the north side. Furthermore, at a position on the side wall 11b opposite the entrance En, trees 7 are planted together with the charging / discharging device 8, making it difficult to see the charging / discharging device 8 from the east side.

[0034] In this embodiment, the charging / discharging device 8 is provided on the rear side (east side) of the side wall 11b of the east side sleeve 11, but it may be provided on the rear side (west side) of the side wall 11b of the west side sleeve 11. That is, since the position of the charging / discharging connection port in the automobile 9 may differ depending on the vehicle model as described above, it may be preferable in some cases to provide the charging / discharging device 8 on the rear side (west side) of the side wall 11b of the west side sleeve 11.

[0035] As shown in FIG. 1, the first site 1A further includes a hill 16, an infiltration basin 18, and a pressure release lid 19 as part of the exterior structure. The mound 16 is provided in the space behind (north of) the parking space 5, and flooring 17 for people to walk on is embedded in the ground around the mound 16. The infiltration basin 18 is buried in the ground of the first site 1A, and makes it easier for rainwater and other water that falls on the first site 1A to infiltrate into the ground. The pressure relief lid 19 releases pressure from the drain pipe when the valve is opened, thereby preventing backflow of drainage water into the house 2.

[0036] In the exterior structure of this embodiment configured as described above, when a disaster accompanied by flooding occurs, the automobile 9 is first parked in the parking space 5. At this time, the automobile 9 is parked in the parking space 5 through the entrance En between the east side gate sleeve 11 and the west side gate sleeve 11, so that the automobile 9 does not come into contact with the charging / discharging device 8 provided on the back side (east side) of the side wall portion 11b of the east side gate sleeve 11. In other words, when parking the automobile 9 in the parking space 5, there is no need to be concerned about the presence of the charging / discharging device 8. In addition, since the charging / discharging connection port of automobile 9 is mainly provided at either the front or rear end of the vehicle body, if the automobile is parked within the area of ​​multiple rows of floor material 5a in parking space 5, assuming that the automobile is correctly parked facing forward or backward, the charging / discharging connection port will be located near charging / discharging device 8. After parking the car 9 in the parking space 5, the water stop 12 that was taken out of the storage space is installed across the front wall parts 11a (between the support parts 12a on both sides) of the gate sleeve parts 11 located on both sides of the entrance En. This makes it possible to close the entrance En.

[0037] According to this embodiment, the following excellent effects are obtained. That is, a removable water stop plate 12 is provided across the front wall portions 11a of the gate sleeves 11 located on both sides of the entrance En, so that the entrance En can be blocked by the water stop plate 12, preventing water from entering the site 1 (first site 1A) in the event of a disaster involving flooding. This prevents the automobile 9 and the charging / discharging device 8 parked in the parking space 5 on the site 1 from being submerged, ensuring an emergency power source in the event of a disaster involving flooding. In other words, the automobile 9 can be considered as part of the infrastructure (electricity infrastructure) and can be used in an emergency. Furthermore, the charging / discharging device 8 connected to the battery of the automobile 9 is installed on the side wall 11b of one of the gate sleeves 11 located on both sides of the entrance En, on the opposite side of the entrance En, so that the charging / discharging device 8 is hidden behind the side wall 11b when viewed from the entrance En side. This ensures that the automobile 9 does not come into contact with the charging / discharging device 8 when passing through the entrance En and proceeding toward the parking space 5, which contributes to ensuring an emergency power source in the event of a disaster involving flooding.

[0038] In addition, since the parking space 5 is located adjacent to the entrance / exit En, even if the car 9 is outside the site in the event of a disaster involving flooding, the car can be immediately parked in the parking space 5 within the site 1. Furthermore, since the parking space 5 is located adjacent to the entrance / exit En, if the automobile 9 is normally parked near the entrance / exit En, charging and discharging can be easily and reliably performed through the charging / discharging device 8 installed near the entrance / exit En, even if the automobile 9 is parked outside the site 1 (first site 1A), for example.

[0039] In addition, of the peripheral wall portion 13 which is formed integrally with the gate sleeve portion 11 and which surrounds the site 1 together with the gate sleeve portion 11, at least the portion 13a on the front side of the site which is provided in the same direction as the gate sleeve portion 11 is set at a lower height than the gate sleeve portion 11. Therefore, visibility to the outside from the site 1 side can be secured through the space above the portion 13a on the front side of the site of the peripheral wall portion 13, and it is also easy to let in light and ventilation.

[0040] In addition, a mesh-like greening fence 14 onto which plants can be entangled is attached to the inside and outside surfaces of the site front portion 13a of the peripheral wall 13, so that the surface of the site front portion 13a of the peripheral wall 13 can be greened. This not only improves the appearance from both the inside and outside of the site 1, but also protects the surface of the peripheral wall 13 and suppresses an increase in the surrounding temperature.

[0041] In addition, since the height of the waterstop 12 and the height of the portion 13a of the peripheral wall portion 13 on the front side of the site are set to be approximately equal, water infiltration into the site 1 can be restricted up to the height of the waterstop 12 and the peripheral wall portion 13. Furthermore, since there is no need to make the height of the waterstop 12 higher than the height of the portion 13a of the peripheral wall portion 13 on the front side of the site, the weight of the waterstop 12 can be reduced by the reduced height, making it easier to carry and attach / detach.

[0042] In addition, since the first site 1A is raised by filling the earth, the ground level at the first site 1A can be positioned higher than the ground level outside the site 1, making it difficult for the site to be flooded. In addition, the second site 1B is inclined downward from the end on the first site 1A side to the end on the opposite side to the first site 1A, so even if the first site 1A is raised by filling the earth, no difference in level is created between the first site 1A and the second site 1B, and the passage of pedestrians and automobiles 9 is not impeded.
