Description

  The present invention relates to a storage provided under the floor of a general house or in the basement of a garage for storing food and drinks and fixtures of the general house.

  It is well known to provide a storage for storing food and drinks under the floor of a kitchen in a general house. This conventional storage is designed to store and take out articles by inserting a hand through the opening on the upper surface, and has a relatively small storage capacity. On the other hand, it has been conventionally performed to provide a basement in a building and use the basement as a storage.

  Japan's ordinary houses are mostly wooden, and there are relatively few basements. In addition, if a basement that can be used as a work place is to be provided, the construction cost increases significantly. On the other hand, in an urban area where it is difficult to obtain a large residential land, the space on the ground can be used more effectively by providing a large storage in the basement.

  Therefore, an underground storage has been proposed that can be called a basement that can be easily installed. This kind of underground storage is a hexahedron space where the above-ground storehouse is installed in the basement as it is, and has an opening (hatch) on the top surface, and an entrance / exit on the floor of the first floor of the building Goes in and out of the ladder.

On the other hand, in the following patent documents, etc., the cylindrical storage under the floor is a vertical cylindrical one, and the storage shelf is rotated around the central vertical axis to increase the storage amount and make it easier to put in and out. Proposed.
JP-A-1-33361 Japanese Utility Model Publication No. 61-170657

  The underground storage is made of steel plate or FRP (fiber reinforced plastics), but the hexahedron storage can not be integrated into a large-capacity storage, causing problems such as water leakage due to increased seams. It is easy to increase the volume, and it is necessary to increase the strength of the wall and floor in order to withstand the increased earth pressure. The strength of the soil must be increased unless the dimension of the wall or floor is increased. Since it cannot resist bending stress caused by pressure, there is a problem that the wall thickness increases and the weight increases, and the structure becomes complicated and expensive due to the reinforcing beams and reinforcing columns.

  On the other hand, the vertical cylindrical structure is convenient as a rotating shelf type structure that does not allow people to enter, but if it is sized to allow people to enter inside and out of storage, people can work. It is difficult to make the arrangement of the space for arranging the shelf and the space for providing the shelf ergonomically suitable, and there is a problem that the work becomes cramped and the storage space is wasted.

  The present invention solves the above problems by providing a horizontal cylindrical underground storage with a diameter that allows a person to enter and work in a standing posture.

  That is, the underground storage according to claim 1 of the present application includes a horizontal cylindrical storage 1 buried underground, a storage space 22 provided on the inner side of both arc side walls, and the storage And a hatch 14 provided on the top of the head. When the storage 1 is provided under the floor of a building, it is embedded in a semi-submerged state so that its top 13 appears on the ground surface (Claim 2). On the other hand, when the storage 1 is provided in the basement of the garage or parking space, the storage 1 is installed in a fully-sunk state so that the entire storage 1 is hidden in the basement, so that the opening of the hatch 14 appears on the ground surface. In the latter case, the opening of the hatch 14 is provided with a lid such as a manhole cover, and the intake / exhaust port is opened under the floor of the building through a duct in the ground.

  The underground storage according to claim 3 of the present application is an underground storage having the above-described means provided under the floor of the building, and has an air vent 16 that opens at the center below the floor of the building via the ventilation duct 5. It is characterized by having. It is preferable that the storage case 11, the end plate 12, and the peripheral wall 15 of the hatch have a multilayer structure including a steel plate, an undercoat coating layer, a heat insulating material layer, a plastic sheet layer, an FRP layer, and a finish coating layer from the inside. ).

  Moreover, the underground storage which concerns on invention of Claim 5 of this application is the temporary storage frame 31 provided with the height adjustment tool 36 which supports the cylindrical bottom face of the said storage 1, in the underground storage provided with said means. The support plate 32 of the cast-in-place concrete that is inflow-solidified between the bottom surface and the ground surface is provided.

  An underground storage according to claim 6 of the present application is an underground storage having the above-described means, and a box-shaped container 40 that stores the lower half of the storage 1 and the box-shaped container. And a support plate 32 of cast-in-place concrete that is solidified by inflow between the box-shaped container and the storage.

  The peripheral wall and end plate of the storage are preferably provided with an FRP spray layer on the outside of the iron plate in terms of strength and corrosion resistance, but it is also possible to have a structure using FRP as a strength member. is there. Of course, the peripheral wall and the end plate may have a multilayer structure in which a coating layer is provided on the inner and outer surfaces, or a water leakage prevention layer is provided to prevent water leakage when a seam is cracked due to a heat insulating layer or an earthquake.

  By providing shelves inside both cylindrical walls, a working space in the direction of the cylindrical axis is formed at the center of the storage. The working space thus formed is convenient for providing the ladder 24 for entering and exiting, and because the shelves on both sides are provided inside the arc wall surface, the depth of the lower and upper shelves is small, and the intermediate height The shelf space is deep and the storage space that is excellent in ergonomics and good workability at the time of putting in and out is wasted in relation to the reach of humans in a standing posture or a squatting posture. It can form without making.

  Underfloor and underground of the building, the temperature change is small compared to the space on the ground, and the temperature rise in summer is particularly small. In order to maintain this preferable environment, the vents 16 and 17 for communicating the inside of the storage and the outside air are opened under the floor of the building, preferably under the floor of the center of the building. On the floor of the building where the storage is provided, it is necessary to provide an entrance to remove or open or close a part of the floorboard. Therefore, the installation location of the storage is limited to the lower part of the kitchen and the lower part of the corridor. It happens that the mouth 16 cannot be opened in the center of the building. In this case, the vent 16 may be opened under the floor in the center of the building through the duct 5 and the underground temperature environment can be used more effectively by arranging the duct 5 through the ground. Can do.

  The installation of the storage of this device involves excavating a part of the ground below the building floor, suspending and installing a factory-produced storage with a foundation on the bottom, and refilling the surroundings with soil. Then, after constructing the solid foundation of the concrete, build the building. When installing the storage on the foundation, the installation height of the storage is set so that the upper edge of the peripheral wall of the hatch 14 is positioned with a slight gap (for example, about 1 cm) on the lower surface of the floor of the building. In addition, after the building is built, a flexible or elastic sealing material 8 is buried in the gap between the upper edge of the peripheral wall of the hatch 14 and the floor slab of the building.

  Cylindrical underground storage can bend a single plate to form a cylinder, so there are fewer seams, which is advantageous for preventing water leakage, as well as reducing the earth pressure by compressive force in the circumferential direction. Since it can resist, it can be manufactured easily and lightly compared with a hexahedral structure.

  In addition to the above-described effects, the storage container has a horizontal cylindrical shape. In addition to the above effects, there is an effect that it is possible to provide an underground storage container that has good workability during storage and removal and is excellent in utilization efficiency of the internal space. Furthermore, by opening the vent hole 16 under the floor in the center of the building via the duct 5, the underfloor or underground environment can be used advantageously.

  In addition, by adopting a basic structure consisting of a temporary support frame 31 that supports the storage, a box-shaped container 40 that stores the lower half of the storage, and a support plate 32 of cast-in-place concrete, workability during installation is improved. There is an effect that it is possible to provide an underground storage that is excellent and that does not cause a gap at the joint between the storage hatch and the floor of the building due to secular change.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a sectional side view showing the underground storage of the present invention together with a part of the floor of the building, FIG. 2 is a front view of the same section, FIG. 3 is a plan view schematically showing the arrangement of ventilation ducts, and FIG.

As shown in FIG. 3, the air supply opening 16 opens below the floor in the center of the building via the ventilation duct 5. A filter (not shown) that prevents intrusion of insects and the like is attached to the opening of the exhaust port 17 and the opening of the ventilation duct 5. The reason why the air supply port 16 and the exhaust port 17 are provided in the end plate 12 is to avoid interference between a duct, a fan case, and the like provided on the outside of the end plate 12 and the floor plate of the building.

  The body 11, the end plate 12, and the peripheral wall 15 of the hatch have a multilayer structure including a steel plate, an undercoat coating layer, a heat insulating material layer, a plastic sheet layer, an FRP layer, and a finish coating layer from the inside. The FRP layer is a layer formed by spraying an unsaturated polyester resin mixed with glass fibers, and serves as a layer for preventing corrosion of the steel sheet serving as a strength member, particularly electrolytic corrosion. The lower plastic sheet is provided to prevent the insulation layer from being filled with bubbles when the FRP is sprayed to reduce the insulation performance.

  The interior of the storage 1 is provided with a work space 21 in the cylinder axis direction at the center of the barrel, and the inner portions of the arc side walls on both sides and both ends of the work space 21 serve as storage spaces 22. In the work space 21, a bottom plate 23 is provided in a corridor shape, and a ladder 24 is wound around the peripheral wall of the hatch 14 so as to be detachably or swingably locked. A shelf frame 25 is provided in the storage space 22, and a storage shelf 27 is formed by spanning a shelf plate 26 over the shelf frame.

  The floor 2 of the building is provided with an entrance 2a continuous with the hatch 14 of the storage, and a door 2b that is a part of the floor is provided at this entrance. A reinforcing bar 7 is fixed to the lower surface of the floor plate 2 so as to surround the floor entrance 2a and the upper edge outside of the peripheral wall 15 on the storage side, and the inner peripheral wall upper edge 15a inside the reinforcing bar 7 and the lower surface of the floor plate 2 Between them, a sealing material 8 having rubbery elasticity is filled. The sealing material 8 is filled after the storage 1 is installed, a building is built thereon, and the floor board 2 is stretched.

  4 and 5 includes a temporary support frame 31 and a support plate 32 of cast-in-place concrete. The temporary support frame 31 is formed by welding both ends of a vertical beam 34 to a U-shaped horizontal beam 33 positioned close to the outside of the end plate 12. It is mounted in a mountain-shaped direction so as to form a slanted slope that supports the frame. At both ends of the horizontal rail 33, a height adjuster 36 composed of an adjusting bolt and a lock nut is provided.

  The foundation of the above structure is that the crushed stone 35 is laid on the bottom surface of the hole excavated for installing the storage 1, the iron plate 37 is laid on the portion provided with the height adjusting tool 36, and the temporary support frame 31 is placed thereon. The storage 1 is suspended so that the peripheral surface thereof is supported by the vertical rail 34, and the upper edge 15a of the peripheral wall of the hatch is lowered by a predetermined gap dimension from the lower surface of the floor board 2 of the building to be built. Leveling is performed by adjusting the height adjusters 36 at the four corners so that they are horizontal. Thereafter, a mold 38 having a height in which the temporary support frame 31 is embedded is installed, and if necessary, reinforcing bars are appropriately disposed, and concrete is poured into the mold and solidified to form the support plate 32. . After that, when the earth and sand are backfilled around the storage 1 and the foundation of the building is used as a solid foundation, the foundation concrete of the building is laid. Of course, the exhaust port 17 and the air supply port 16 are provided so as to be located above the foundation of the building.

  The installation position of the storage 1 is limited to a place that is convenient for taking in and out of storage items such as under a kitchen or a corridor, and where the door plate 2b can be provided on the floor. The air supply port 16 for ventilation of the storage 1 is preferably opened under the floor in the center of the building. Therefore, if necessary, a ventilation duct 5 as shown in FIG. 3 is arranged to open the air supply port 16 at the center below the floor of the building.
