Description

  The present invention relates to a floating building, particularly a building that floats on water.

  Patent document 1 discloses a floating type building. Since the building is floating in the pool, it can be protected from damage caused by the earthquake. The water in the pool can be used as emergency water for emergencies.

JP-A-9-151623

  Patent Document 1 does not consider any measures for water leakage in a pool. If water leaks, the building sinks with the water level and cannot be used as a residence. Even if the pool is hardened with concrete, the water pressure is high, so even a slight crack will leak water. In order to repair the water leakage, it is necessary to drain the pool, but if the water is drained, the building will reach the bottom, so it is not possible to inspect or repair the water leakage under the building. It is also possible that the building will be damaged by the descent at the bottom.

  The present invention provides a floating building capable of inspecting and repairing water leakage and the like. In one embodiment, a floating building that is unlikely to cause water leakage or the like is also provided. In a further aspect, a buoyant building capable of wave extinction such as during an earthquake is also provided.

  The present invention includes a buoyancy body for generating buoyancy, a building supported by the buoyancy of the buoyancy body, and a support member, and when the fluid is injected into the support member, the support member is The floating building is characterized by supporting the load.

  In the present invention, when the fluid is injected into the support member, the support member supports the load of the building, so that water can be drained without lowering (or not significantly lowering) the building. Therefore, it is possible to inspect and repair the repair area including under the building.

1 shows a floating building 1 according to an embodiment of the present invention. The structure of the laminated sheet 14 is shown. The usage of the floating building 1 at the time of repair is shown. The support member 50 of a deformation | transformation form is shown.

  FIG. 1 shows a floating building 1 according to an embodiment of the present invention. The buoyant building 1 includes a pool 10, a buoyant body 20 that floats in the pool 10, and a building 30 that is built on the buoyant body 20. In the pool 10, a crushed stone layer 12 and discarded concrete 13 are laid on the bottom of a hole 11 provided on the ground, and a laminated sheet 14 is stretched on the outer periphery of the hole 11 and the upper surface of the concrete 13.

  FIG. 2 shows the structure of the laminated sheet 14. The laminated sheet 14 includes a plurality of water shielding sheets 14a and protective sheets 14b that are alternately laminated. The water-impervious sheet 14a is a sheet that does not allow water to pass through, and can be formed of, for example, a synthetic resin such as polyethylene, rubber, or the like. The protective sheet 14b is a puncture-resistant sheet that does not allow sharp stone, glass, metal, or the like to pass through, and can be formed of, for example, a nonwoven fabric or urethane. The outermost layer of the laminated sheet 14 is preferably a water shielding sheet 14a. Preferably, a three-layer water-proof sheet 14a and a two-layer protective sheet 14b are laminated.

  A wave-dissipating structure 15 may be disposed on the outer periphery of the pool 10. The wave-absorbing structure 15 can be formed of cement, concrete, or the like. The wave-dissipating structure 15 is preferably a structure having many gaps. As shown in the figure, a conical block may be alternately stacked and stacked in a vertical direction, and a tetrapod may be used. As shown in the figure, the laminated sheet 14 may cover the wave-dissipating structure 15. A stopper for draining water may be provided at the bottom of the pool 10.

  The buoyancy body 20 is a member that generates buoyancy, and can be formed of, for example, a hollow metal box or lightweight wood. The buoyancy body 20 generates buoyancy that supports the weight of the entire building 30.

  The building 30 has a building foundation 31 and a building body 32. A cushion material 16 may be disposed between the building 30 and the side wall (or the wave-dissipating structure 15) of the pool 10. The cushion material 16 can be a rubber material, an old tire, or the like. It is preferable to pass a plate 17 between the building 30 and the side wall of the pool 10 so that a person does not fall into the pool 10. As illustrated, the outer end of the plate 17 may be bent and embedded between the laminated sheet 14 and the side wall of the hole 11.

  A support member 40 that supports the load of the building 30 when fluid is injected is attached to the buoyancy body 20. Although various structures can be considered for the support member 40, the support member 40 of the present embodiment includes an extension member 41, a weight 42, and a fluid injection port 43.

  The weight 42 plays a role of maintaining the buoyancy body 20 in a substantially vertical position (an attitude in which the length direction of the buoyancy body 20 substantially matches the Z direction in FIG. 1). In FIG. 1, the weight 42 is in contact with the water bottom 10a of the pool 10, but it may not be in contact (the weight 42 may be suspended in water).

  The expansion member 41 is a member that expands when a fluid (for example, air or water) is injected from the fluid injection port 43. The extension member 41 can be formed of a bellows tube such as plastic or hard rubber. The extension member 41 is pulled downward by the weight 42 during normal times.

  In the buoyant building 1, the building 30 floats on the water by the buoyancy of the buoyant body 20, so that the building 30 can be protected from damage caused by an earthquake. During normal times, the support force (upward force in the Z direction) by the support member 40 does not act on the building 30 at all. Therefore, the earthquake motion is not transmitted (or hardly transmitted) to the building 30 via the support member 40. Since the wave-dissipating structure 15 is installed between the building 30 and the peripheral wall of the pool 10, it is possible to suppress the generation of waves due to an earthquake and the shaking of the building 30 caused by the waves.

  In the levitation building 1, the side surface and bottom surface of the pool 10 are the laminated sheets 14, so that cracks, tears, tears, water leaks, and the like due to earthquakes are less likely to occur. Still, tears and water leaks during long-term use cannot be completely ruled out, and repair and inspection are required. FIG. 3 shows the usage of the floating building 1 during inspection and / or repair.

  First, the expansion member 41 is expanded by injecting a fluid from the fluid injection port 43. The support member 40 (the weight 42) is pressed against the water bottom 10a by the force by which the extension member 41 extends, and the reaction force generates a support force in the Z direction with respect to the building 30. When the fluid is injected until the supporting force substantially matches the weight of the building 30, the pool 10 is drained. As a result, the building 30 is supported only by the support member 40 as shown in FIG. 3, and inspections such as tears, tears, and water leaks, and repairs thereof can be performed. Since the building 30 does not descend greatly when draining water, damage to the building can be prevented. In order to reliably prevent the building 30 from descending, the fluid injection pressure may be controlled according to the Z-direction position of the building 30 when draining water. Control means such as a computer may be used for the control.

  When inspecting for tearing or the like, it is easy to find out if a colorant is poured in a state where water is accumulated for several centimeters. In FIG. 3, the extension member 41 is shown thicker in order to show how the fluid flows into the extension member 41, but it is only necessary to generate a force that extends in the Z direction, and the thickness of the extension member 41 changes. Is not required. Although only two support members 40 are shown in the drawing, the number and arrangement of the support members 40 are arbitrary.

  FIG. 4 shows a modified support member 50. The support member 50 includes an inner cylinder 51 fixed to the building foundation 31, a bottomed outer cylinder 52 slidable with respect to the inner cylinder 51, a bag body 53 accommodated in the inner cylinder 51, and a bag body 53. There is a fluid inlet 54 in communication. The vicinity of the upper end of the bag 53 is connected to the vicinity of the upper end of the inner cylinder 51 through a connecting member 51a such as a metal wire. The bag 53 can be formed of a stretchable rubber tube or the like. The bag 53 preferably has a bellows shape.

  When inspecting and / or repairing tears or the like, the bag body 53 is inflated by injecting fluid from the fluid inlet 53a. As a result, as shown in FIG. 4B, the bag body 53 expands and the outer cylinder 52 descends with respect to the inner cylinder 51. As a result, the support member 50 expands and comes into contact with the water bottom 10a. Support force for 30 is generated.

  Although the case of the pool 10 using the laminated sheet 14 was shown in the said embodiment, the pool 10, such as concrete, may be sufficient. In addition, the matters described in the above-described embodiment and the dimensions, shapes, arrangements, numbers, materials, etc. thereof, which are not described in the claims, are merely examples, and limit the claims. is not.

  The present invention can be used for a floating building. The building can be of any type, such as a house, condominium, or office building.
