Further, by the three pulley fixtures 25a installed on the upper surface of the pulley mounting base 9b of the connecting member 9, the three moving pulleys 8a have a rotation axis parallel to the rotation axis of the fixed pulley 8b in the same plane as the fixed pulley 8b. Each is held rotatably as a center.

The wire rope 7 is alternately wound around the three moving pulleys 8a and the two fixed pulleys 8b, and both ends are wound around the rollers (not shown) of the two winches 6 and 6, respectively.
That is, the seismic isolated house 1 has a structure in which the living space 2 is lifted via the connecting member 9 by rotating the rollers of the two winches 6 and 6 to wind up both ends of the wire rope 7. When the rollers of the two winches 6 and 6 are rotated in the opposite directions to the above, both ends of the wire rope 7 are wound down, so that the living space 2 is lowered.

When the living space 2 is suspended by the winch 6 via the wire rope 7 (see FIG. 1), a tension of a predetermined magnitude is generated in the wire rope 7. Assuming that the magnitude of this tension is T, as shown in FIG. 8, a downward force having a magnitude of 2T is applied to the two fixed pulleys 8b via the wire rope 7, but the two winches 6 and 6 are subjected to a downward force. Is that only a downward force of magnitude T is applied through the wire rope 7, respectively. In this case, the force with which the winch 6 winds up the wire rope 7 is T.

On the other hand, an upward force having a size of 2T is applied to each of the three moving pulleys 8a via the wire rope 7, and the upward force having a total size of 6T is applied to the three moving pulleys 8a and the connecting member 9. Is balanced with the total weight of the living space 2. That is, in the seismic isolated house 1, it is possible for the two winches 6 and 6 to wind up an object having a weight equivalent to 6 times the force for winding up the wire rope 7.

The number of moving pulleys 8a and fixed pulleys 8b is not limited to those shown in FIGS. 7 and 8. For example, when the number of moving pulleys 8a is n and the number of fixed pulleys 8b is (n-1), the winch 6 lifts an object having a weight equivalent to n times the force at which the wire rope 7 is wound up. Will be. That is, in the seismic isolated house 1, since the winch 6 does not have to have a high hoisting ability, it is possible to reduce the manufacturing cost by using a small and inexpensive winch.

9 (a) is a cross-sectional view taken along the line BB in FIG. 1, and FIG. 9 (b) is an enlarged view of a portion F shown in FIG. 9 (a). In FIG. 9A, the wire rope, the moving pulley, and the connecting member are not shown.
As shown in FIGS. 9A and 9B, the four guide members 11a attached to the living space 2 surround the support column 3 and are formed of weather-resistant rubber on the four side surfaces 3c. The four guide rollers 26 arranged so as to be close to each other, the four holding metal fittings 27 that rotatably hold the four guide rollers 26 about the horizontal rotation axis, and the four holding metal fittings 27 on the inner surface. It is composed of a frame body 28 that is externally attached to the support column 3 while being attached to the support, and a fixing bracket 29 that fixes the frame body 28 to the living frame 18 (see FIG. 3) of the living space 2.
The material of the guide roller 26 is not limited to the rubber described above, and may be any material having weather resistance and elasticity. For example, the guide roller 26 can be formed of a synthetic resin such as an elastomer.

According to such a structure, the guide roller 26 comes into contact with the side surface 3c of the support column 3 even when the living space 2 suspended via the wire rope 7 swings due to the influence of wind or the like. Therefore, it acts to prevent damage to the frame body 28 due to interference with the support column 3.
Further, when the living space 2 vibrates in the vertical direction, the guide roller 26 abutting on the side surface 3c of the support column 3 rolls along the side surface 3c of the support column 3, so that the support roller 3 joins the frame body 28 in the vertical direction. The power weakens.
Further, in the seismic isolated house 1, even if the living space 2 swings due to the influence of wind or the like and the guide roller 26 collides with the side surface 3c of the support column 3, the guide roller 26 elastically deforms and the support column 3 Since the impact force applied to the guide roller 26 is relaxed, the guide roller 26 is not easily damaged.
As described above, the seismic isolated house 1 can be safely used for a long period of time because the guide member 11a is not easily damaged.

10 (a) is a perspective view showing the appearance of the living frame, the reinforcing frame, the bottom plate, and the wall plate constituting the living space shown in FIG. 1, and FIG. 10 (b) is a wall plate in FIG. 10 (a). It is the figure which showed the state which omitted the illustration of the bottom plate.
11A is a perspective view showing the appearance of the living frame, the foundation frame, the reinforcing frame, the bottom plate, and the wall plate constituting the living space shown in FIG. 1, and FIG. 11B is FIG. 11 (b). It is a figure which showed the state which omitted the illustration of the wall plate and the bottom plate in a).

As shown in FIGS. 10A and 10B, the living frame 18 of the living space 2 is installed at each end of the four side plates 2a (see FIG. 1) to form each side of the rectangular parallelepiped. It consists of 12 shaped steels 5c combined as described above.
Further, the living space 2 is orthogonal to two pairs of parallel side plates 2a and 2a, respectively, and is provided with a pair of rectangular wall plates 2d and 2d installed so as to be orthogonal to the bottom plate 2b and the pair of walls. A reinforcing frame 30 made of eight shaped steels 5d installed at each end of the plates 2d and 2d and combined so as to form each side of a rectangle is provided. That is, the living space 2 has a structure in which the space surrounded by the four side plates 2 is divided into four rooms by a pair of wall plates 2d and 2d. Although not shown in FIG. 10A, the pair of wall plates 2d and 2d are provided with doors for moving to each room.
As described above, the seismic isolated house 1 is excellent in safety because the rigidity of the living space 2 is increased by the reinforcing frame 30.

As shown in FIGS. 11A and 11B, the base frame 19a of the living space 2 constitutes each side of a quadrangular pyramid having a square bottom surface and all four ridges having the same length. It consists of eight shaped steels 5d combined with.
The lower end of the connecting member 9 is connected to the apex of the base frame 19a, and the lower ends of the pair of wall plates 2d and 2d form diagonal lines of the square and are orthogonal to the bottom surface of the base frame 19a. It is installed like this.
Further, the bottom surface of the foundation frame 19a is on the same plane as the living frame 18, and the bottom plate 2b of the living space 2 is installed parallel to the bottom surfaces of the living frame 18 and the foundation frame 19a. The four columns 3 are arranged so as to be close to each apex of the square formed by the bottom surface of the base frame 19a when viewed in a plan view.

In a living structure provided with such a living space 2, the four shaped steels 5d forming the ridgeline of the base frame 19a of the living space 2 are embedded in a pair of template plates 2d and 2d. There is no risk that the shaped steel 5d will interfere with life in the living space 2. Then, the above-mentioned four shaped steels act to increase the strength of the pair of wall plates 2d and 2d. Therefore, the resident of the living structure can effectively use the space inside the living space.

Then, in the seismic isolated house 1 having such a living structure, four columns 3 arranged in close proximity to each apex of the square forming the bottom surface of the foundation frame 19a when the living space 2 is viewed in a plan view. Four guide members 11a are arranged in the vicinity of each of the above, and its posture is unlikely to change when the living space 2 moves in the vertical direction. Further, the foundation frame 19a has a structure in which a perpendicular line extending from the apex to the bottom surface passes through the center of gravity of the bottom surface. Therefore, when the living space 2 moves in the vertical direction, the vertical line of the foundation frame 19a is maintained in a state of being parallel to the vertical direction. In this case, the weight of the living space 2 acts evenly on the four shaped steels 5d forming the ridgeline of the foundation frame 19a.

In this way, in the seismic isolation house 1, when the winch 6 lifts the living space 2 via the wire rope 7, the weight of the living space 2 is evenly distributed to the four shaped steels 5d forming the ridgeline of the foundation frame 19a. Since the structure is added, the living space 2 suspended by the winch 6 via the wire rope 7 is not likely to be deformed or damaged, and is excellent in safety.
Further, according to the seismic isolated house 1, the damage caused by the tsunami, the flood, or the like can be surely avoided by lifting the living space 2 by the winch 6. Further, since the posture of the living space 2 is unlikely to change during movement, it is possible to move the living space 2 to an accurate and safe height in a short time.

Further, since the seismic isolation house 1 is equipped with a storage battery, power cannot be supplied from the power transmission line when the power transmission from the power plant is stopped due to the occurrence of a disaster such as a tsunami or the living space 2 is suspended. Even in the state, the storage battery provides the electric power required for living in the living space 2. Therefore, in the living space 2, it is possible to live for a certain period of time.
In the seismic isolated house 1, the electric motor 23 (see FIG. 6) can be driven by the electric power supplied from the storage battery, so that even if the power transmission from the power plant is immediately stopped due to the occurrence of a disaster. By moving the living space 2 upward so as not to be affected by the tsunami, the safety of the resident can be promptly ensured.
Further, since the seismic isolated house 1 is provided with the solar power generation facility 10 for charging the storage battery, even if the power supply from the transmission line continues for a long time, there is no problem in the living space 2. Can live in.

Here, the guide member 11b according to the modified example of the guide member 11a will be described with reference to FIG. Note that FIG. 12 is a diagram corresponding to FIG. 9A showing the guide member 11a.
As shown in FIG. 12, the guide member 11b is characterized in that the fixing bracket 29 is fixed to the living frame 18 of the living space 2 via the coil spring 31 in the guide member 11a. The coil spring 31 may be either a compression spring or a tension spring. Further, not only the coil spring 31 but also an air spring or a member having elasticity can be used.

According to such a structure, even if the living space 2 suspended via the wire rope 7 swings due to the influence of wind or the like, the positional relationship between the living space 2 and the support column 3 changes. Since the living space 2 is returned to the correct position by the urging force of the coil spring 31, it is possible to move the living space 2 to an accurate and safe height in a short time.
Further, even when the living space 2 swings and the support column 3 comes into contact with the guide roller 26, the coil spring 31 acts to relieve the force applied to the guide roller 26 from the support column 3, so that the guide member 11b is damaged. hard. This improves safety during use.

FIG. 13A is a diagram showing a living space 32a according to a modified example of the living space 2, and FIG. 13B is a diagram for explaining a difference in internal size between the living space 2 and the living space 32a. Is. Both FIGS. 13 (a) and 13 (b) are views corresponding to FIG. 9 (a) relating to the living space 2.
As shown in FIG. 13A, the living space 32a corresponds to a state in which the bottom surface of the living frame 18 is aligned with the bottom surface of the base frame 19a in the living space 2. In this case, the bottom area of the living frame 18 is equal to the bottom area of the base frame 19a. Therefore, as shown in FIG. 13B, the bottom area of the living space 32a (the area of the bottom surface of the foundation frame 19a) is half the bottom area of the living space 2 (the area of the bottom surface of the living frame 18).
That is, in the seismic isolated house 1, when the living space 2 is viewed in a plan view, its corners protrude from between the two columns 3 and 3, and the living space 32a is contained in the space surrounded by the four columns 3. Since the interior of the living space 2 is wider than the case where the entire living space 2 is installed, it is possible to effectively use the internal space of the living space 2.

FIG. 14 is a diagram showing a living space 32b according to a modified example of the living space 2, and is a diagram corresponding to FIG. 9A related to the living space 2.
As shown in FIG. 14, the living space 32b is characterized in that, in the base frame 19a of the living space 2, the bottom surface is not a square but a rhombus in which all four internal angles are not right angles.

In this case, the four columns 3 form each vertex of a rectangle instead of a square when viewed in a plan view. However, even with such a structure, the base frame 19b has a seismic isolation house 1 provided with a living space 2b having the foundation frame 19a described above because a perpendicular line from the apex to the bottom passes through the center of gravity of the bottom. The actions and effects in the above are similarly exerted.

In the above-described embodiment, the support column 3 is a square tube, but the present invention is not limited to this, and the support column 3 may be a circular tube. Further, depending on the area or place where the seismic isolated house 1 is installed, the strength of the support column 3 may be increased by filling the inside of the support column 3 with concrete. Furthermore, the length of the pillar 3 is set to 10 m or more in the coastal area, which is easily damaged by the tsunami, and 3 to 5 m in the mountainous area, where floods and debris flows are likely to occur. It is desirable to set according to.
Further, the living space 2 may be a cube instead of a rectangular parallelepiped. Further, in the guide members 11a and 11b, the number of guide rollers 26 installed inside the frame body 28 is not limited to four, and can be changed as appropriate.
Further, instead of winding both ends of the wire rope 7 with two winches 6 and 6, one end of the wire rope 7 is fixed to the reinforcing member 5, and the other end of the wire rope 7 is wound with one winch 6. You can also do it.
In any of the above cases, the actions and effects of the present invention described with reference to FIGS. 1 to 14 are similarly exhibited.

The present invention can be used not only in coastal areas that are easily damaged by tsunamis, but also in mountainous areas where floods and debris flows are likely to occur.
