<Example> Next, an example of the invention of this application will be described below based on the drawings.

In the embodiment shown in Figures 1 to 8, a house building 1 has already been constructed, and an underground storage 5, which is one of the main points of the invention of this application, is buried in the ground 4 under the floorboard 3 of a predetermined room 2. The mode is shown.

Therefore, as shown in FIG. 1, the formed underground warehouse 5 cannot be seen from the outside of the house building 1 at all, and is structurally integrated with the house building 1.
The opening 6 of the floor plate 3 can be freely opened and closed via a lid 7 formed as appropriate to allow access via a ladder or stairs. 9, and the floor plate 3 and the ground 4 are blocked by a wall plate 10.
Therefore, the underground warehouse 5 is formed as a kind of attached room so that it can communicate with the room 2.

To explain the construction process of the underground warehouse 5, as shown in FIG. They can be integrally joined to form a rectangular shape in plan view, and a shelf 11 is integrally formed at a predetermined height portion of the inner surface of the rectangle by welding or by appropriate means such as a hanger.

As described above, the main body side plate 8 is divided into four parts in the circumferential direction and is pre-produced in a factory, so that it can be easily transported into the room 2 of the house 1.

On the other hand, in the house building 1, as shown in FIG. 3, the floorboard 3 of a predetermined room 2 is cut out to a predetermined size to form an opening hole.

At the same time, the joists 12 and 13 under the floorboard 3 are also removed, and the flooring that becomes an obstacle is also removed.

Therefore, as mentioned above, each corrugated plate of the main body side plate 8 and the shelf 11, which were prefabricated in a factory, were brought into the room 2 and assembled or welded and joined to form the main body side plate as shown in FIG. 8 is assembled in the hole 6 of the floor plate 3 and installed upright on the ground 4.

By the way, as shown in FIG. 3, a worker 14 enters the main body side plate 8 from above through the hole 6, excavates the ground 4 inside using a tool such as a scoop, and the excavated earth and sand 15 is The excavated soil 15 is piled up on a shelf 11 provided inside the main body side plate 8.

Incidentally, the excavated earth and sand 15 may be piled up near the upper end of the main body side plate 8 instead of the shelf 11 described above.

Incidentally, the main body side plate 8 inherently has a considerable weight, and when the excavated soil 15 placed on the shelf 11 is added to this weight, the gravity becomes considerably heavy. As the ground 4 inside is excavated, the main body side plate 8 sinks due to this gravity.

Therefore, by proceeding with such a process, the main body side plate 8 gradually sinks due to the gravity that increases with excavation.

In addition, during this time, the excavated earth and sand 15 accumulated on the shelf 11 is carried out from the room 2 to the outside and disposed of.

In addition, if it is possible to sink by the weight of the main body side plate 8 itself even if there is no excavated soil 15 placed on the shelf 11 due to the design and the nature of the ground 4, the gravity of the excavated soil 15 described above may be used. You don't have to.

In this way, the main body side plate 8 sinks to the set depth due to excavation settling, and when its upper end 16 coincides with the surface of the ground 4, as shown in FIG. 4, the excavation of the ground 4 is stopped and the internal bottom surface is A suitable moisture-proofing material 17 is laid on each of the flat shapes, and a steel bottom plate 9 is laid on the upper surface thereof, and is joined to the lower end of the main body side plate 8 by welding to form an integral seal.

Note that a concrete floor may be placed instead of the bottom plate 9.

As shown in FIGS. 5, 6, and 7, a receiving plate 18 made of a rectangular steel flat plate having a width corresponding to the wave width of the corrugated plate of the main body side plate 8 at the upper end 16 of the main body side plate 8 is prepared in advance.
This is carried into the room 2, carried through the hole 6 onto the upper end 16 of the main body side plate 8, placed thereon, and integrally welded and joined together using the wave width.

Incidentally, the flat plate 18 may be used as an entrance by increasing the width of its periphery.

Next, a wall plate 10 having a height from the ground 4 to the height of the floor plate 3 is made of a steel flat plate and also has a square cross section.
is carried into the room 2, placed on the receiving plate 18 through the hole 6, and welded at the inner edge of the receiving plate 18 to be joined and integrated as shown in FIG.

Therefore, the weight of the wall plate 10 is supported by the main body side plate 8.

As shown in FIG. 5, the earth pressure from the sides of the ground 4 is sufficiently countered by the corrugated plates such as the keystone plates of the side plates 8 of the main body, so that its shape retention is maintained.

Further, since there is no soil pressure between the ground 4 and the floor plate 3, it is sufficient to use a flat plate as the wall plate 10 as a partition wall from the surroundings.

After the wall board 10 is formed in this way, as shown in FIG. Further, the force of the joists 12 and the drawers 13 applied to the flooring 19 can be supported by the corrugated main body side plates 8 via the receiving plates 18.

The arrangement of these multilayered structures is as shown in FIG.

Also, when carrying or placing the receiving plate 18 or the wall plate 10 on the main body side plate 8, or during welding or joining work, the shelf 11 provided on the inner surface of the main body side plate 8 is used.
Of course, it can be used as a work scaffold and also function as a storage area for daily necessities after completion.

In this way, when the underground construction of the underground warehouse 5 is completed, a cover body 7 that can be opened and closed as appropriate is made on the upper part of the wall plate 10, and is formed to match the level below the main drawer 13. All work is completed by installing tatami mats, carpets, etc. through the specified spacer material.

In addition, in order to prevent moisture in the ground 4 and between the ground 4 and the floorboard 3, steel plates with sufficient corrosion resistance have recently been commercially available, and these can be used. It is fully put to practical use.

When in use, the lid 7 is opened and closed, and a ladder (not shown) is placed between the floor plate 3 and the bottom plate 9 of the main body side plate 8 to store daily necessities. It is placed on the shelf 11, etc.

In addition, if the space between the floorboard 3 and the ground 4 is large due to the design and the size of the wallboard 10 becomes large, the wallboard 10 may also be provided with a top cover, but in that case, In order to increase its rigidity, as in the embodiment shown in FIG.
An arched portion 10' may be formed throughout.

It goes without saying that the embodiments of the invention of this application are not limited to the above-mentioned embodiments; for example,
It is possible to create a structure by connecting ducts to the wall board and installing ventilation holes in appropriate areas, and the construction method is not to do it after the construction of the house as shown in the above example, but after the construction is scheduled. Various methods can be adopted, such as constructing an underground warehouse in the ground in advance and then constructing a house.

In addition, various design changes are possible; for example, as the corrugated plate of the side plate of the main body, in addition to the keystone plate as in the above embodiment, it is also possible to use, for example, a sine curved corrugated plate.

<Effects of the Invention> According to the invention of this application, basically, even when a large house building such as a general residence for civilian use is constructed on the site, or even before construction,
By constructing a warehouse for storing daily necessities, etc., buried underground under the floorboards of a designated room in the house, ground space can be fully utilized, and the building coverage ratio can be improved. The excellent effect of being able to create a warehouse with almost no connection is achieved.

Underground warehouses are not affected by earthquakes, wind and rain, and because they are buried underground, they are protected by the ground and can maintain their shape well. Moreover, the excellent effect of good durability is exhibited.

Also, because it is underground, it has the effect of becoming a constant temperature room.

Since the underground storage is connected through the floorboards of the rooms, there is no need to go outside every time, and household goods and daily necessities can be taken in and out very smoothly, which is an excellent effect.

Furthermore, since the side panels of the underground warehouse are made of corrugated plates such as keystone plates, they can withstand the earth pressure of the ground. It has the excellent effect of having sufficient resistance to the vertical gravity of daily necessities and the like.

In addition, the side panels of the main body can be made of corrosion-resistant materials such as steel, so they can be used semi-permanently, and have the advantage that moisture does not enter, and the drying properties are better than in warehouses built outside. There is also.

Furthermore, a receiving plate having the same width as the wave width is welded to the upper end of the side plate of the main body, and a wall plate is placed on top of it, welded,
Even if the wall board itself indirectly supports the weight of household goods and the floor through the floor board due to joining, etc., the width of the receiving board at least matches the wave width of the main body side board. Moreover, since the indirect support load is eventually transmitted to the main body side panels through the floorboards, there is an excellent effect that the main body side panels sufficiently support the house load via the floorboards.

In addition, in the underground manufacturing construction method for underground warehouses, holes are drilled inside the side plates of the main body installed in the ground, and the gravity of the main body itself or the excavated earth and sand are applied to the inside of the side plates of the main body. Gravity can be increased by placing the main body side plate on a shelf etc. installed in the ground, thereby allowing the main body side plate to sink into the ground via gravity, and the main body side plate can be placed on a shelf etc. installed in the ground. It becomes possible to bury the main body in the ground, and therefore, an excellent effect is achieved in that the main body side plate can be sufficiently sunk and buried in the ground even in a narrow space in an existing house building.

In addition, a gap is created between the outside of the main body side plate and the ground because the ground is excavated into the internal hole of the main body side plate, the excavated soil is carried out to the outside of the main body side plate, and the main body side plate is settled by gravity and buried. without any
Therefore, for existing buildings, there is no need to perform construction work such as backfilling on the outside of the main body side panels later without damaging the foundation, and therefore the number of man-hours is reduced.
The excellent effects of easier work and lower cost can be achieved.
