Description

[Detailed explanation of the invention] ``Purpose of the invention'' This invention relates to the invention of an underground structure, which is suitable for each household or small-to-medium-sized business, and is suitable for providing comfortable living and living for a considerable period of time within a relatively small construction area. The aim is to provide a relatively compact and low-cost underground structure.

Industrial Application Fields: Underground structures to avoid disasters such as earthquakes and fires, or to be used as living areas.

PRIOR TECHNOLOGY It seems that some measures have been taken to provide evacuation facilities in the event of disasters such as earthquakes and fires, but in Japan, these measures are limited to simply providing evacuation plazas and cannot be perfected. Worldwide, it has become popular in countries such as Switzerland, Sweden, the Soviet Union, and the United States. That is, in the case of an underground type, each member is carried into an excavation part at the site and assembled, and is formed as a hollow body in a rectangular or other rectangular shape.

The inventor of this invention was Utility Model Publication No. 57-99058 (Utility Model Publication No. 61-14522)
As a method, a plurality of unit parts are connected at open ends, using unit parts made of cross-connected pipes, and forming a surrounding area between the unit parts by the unit parts,
It is proposed that the unconnected remaining open end of the unit body be provided with an entrance/exit body or an end plate for closing the open end and buried underground.

Problems to be Solved by the Invention However, the conventional methods described above require considerable man-hours and time, and are also expensive. That is, the site is excavated, formwork is constructed, concrete is poured, and after curing and hardening, each construction and installation is performed, which requires a considerable amount of man-hours and time, and is inevitably expensive.

The proposed Utility Model Application No. 57-99058 proposed by the inventor has the advantage of being able to easily construct underground facilities using steel pipes, etc., but it is possible to easily construct underground facilities using steel pipes.
Since a surrounding area is formed by these unit parts between the unit parts, it is necessary to use at least four unit parts and arrange them in a surrounding manner, resulting in a large-scale facility and a large construction area. It is large, over ^100m2 , and is not suitable for use by individuals, households, or small and medium-sized businesses. Furthermore, even though it is large-scale and suitable as a temporary evacuation facility for use by a large number of people, as mentioned above,
Since such a large number of users generally enter and move along the pipe axis direction through the entrance and exit formed at the end of the pipe, the entire interior of each pipe is always a passage area, and the entire cross-sectional structure is occupied or not occupied. It is not suitable for long-term quiet use as a bedroom.

``Structure of the invention'' Means for solving the problem An outer shell is used in which pipes are assembled in a cross-shaped manner, and one pipe in the outer shell is made into a continuous living area or sleeping area, and such one The interior of the other tube protruding from the other tube body is used as a toilet and a toilet, and an entrance and exit is provided on the side surface of the other tube body in a direction parallel to the outer surface of the one tube body, and An underground structure characterized in that another vertical passage section reaching the ground is provided on the outside of the one pipe body.

Function The outer shell, which is made up of pipes assembled in a criss-cross pattern, is set stably against the soil layer, and eliminates the complexity of having to perform each construction after excavation at the construction site, using formwork, pouring concrete, and curing and hardening. Aim to shorten construction period.

By making one tube in the outer shell a continuous living area or bedroom, a living space is formed linearly within the limited tube.

The above-mentioned method is achieved by providing a toilet and a toilet inside the other tube protruding from the one tube, and providing an entrance and exit in a direction parallel to the outer surface of the one tube on the side of the other tube. The facilities necessary for daily life in the living quarters or bedrooms in one tube are formed in the other tube, so that the living space in one tube is not obstructed by those incidental facilities. , making it possible to live comfortably for a long period of time.

As mentioned above, one of the tubes has a vertical passageway that reaches the ground level, so if it sinks into the ground and the entrance/exit part formed in the other tube gets blocked by surrounding landslides, etc. Even in such a case, it is possible to evacuate directly to the ground from within one of the pipes forming the living space.

The passage provided in one tube is vertical, and the entrance and exit formed in the other tube is provided along the axial direction of one tube, which reduces the amount of land required for installation. This means that the setting area of the outer shell is substantially sufficient, ranging from several tens of m ² to 100 m ² , and can be sufficiently adopted for home use and small and medium-sized businesses.

Embodiment A specific embodiment of the present invention as described above will be described with reference to the attached drawings. An entrance/exit 11 is formed in the other tube body 1a near the intersection of the shell bodies 10 in a direction along the axial direction of one tube body 1, and a continuous living area or sleeping area 2 is formed inside the one tube body 1. and the other tube 1a protruding from the one tube 1
A kitchen 3 and a toilet 4 are formed inside the part that protrudes from one of the pipe bodies 1, and the outside of the part of the above-mentioned one pipe 1 that protrudes from the other pipe body 1a to the opposite side of the part where the entrance/exit 11 is formed. A vertical passage 5 is formed for escaping to the ground, and an outside air intake port 6 is bent downward at the top of the vertical passage 5. Further, an explosion-proof valve and a purification filter 7 are provided on the end wall surface of one of the pipe bodies 1, and an air supply duct 15 from the vertical passage section 5 is attached to the valve and filter 7, and a ventilation means 17 is connected. pipe body 1, 1a
The internal atmosphere is ventilated and the internal air, which has been appropriately pressurized, is discharged to the outside via a pressure-resistant check valve 8.

In addition, as shown in FIG. 3, the device according to the present invention is provided with the other tube 1a only on one side of the other tube 1, and the kitchen 3 and A toilet 4 may be formed. Further, as shown in the figure, an entrance box 12, stairs 13, etc. are further attached to the entrance 11, and a door 1 is provided between each of the above-mentioned parts.
4 are arranged. Furthermore, a floor plate 18 is provided on the inner surface of the bottom of each tube body 1, 1a to make it suitable for walking, and the floor plate 18 is provided with a storage opening 19 as shown in FIG. 4 or FIG. It is designed to store food, drinks, and other daily necessities.

The vertical passage 5 can optionally be formed in the end face of one of the tubes 1, as shown in FIGS. 4 and 5, or in the illustrated embodiment using cylindrical tubes 1, 1a. A shelf 21 is appropriately formed on the side wall portion of the product that bulges outward to place and organize equipment, members, etc., and to efficiently utilize the internal space.

An opening/closing lid 22 is attached to the top opening of the vertical passage section 5 described above, and the inner surface of the opening/closing lid 22 and the inner surface of the vertical passage section 5 are painted white or coated with a glittering coating or plate material (for example, stainless steel plate). By forming a reflective surface 16 such as that shown in FIG.

That is, since the device according to the present invention uses pipe bodies 1 and 1a such as steel pipes, there is virtually no need for concrete pouring on site, and it can be easily constructed by simply burying the pipe after excavation. Since one pipe body 1 is continuously used as a living area or a bedroom, even if pipe body 1 is used, it forms a relatively long linear living space and does not create a visually cramped feeling. By making the entrance, kitchen, toilet, etc. inside the other pipe that intersects with one pipe, the living space will not be obstructed by such equipment, and the equipment will not interfere with the living space. It is possible to lead a comfortable life for quite a long time.

By opening the entrance/exit 11 along the outer surface of one of the pipe bodies 1, the outer surface of the one pipe 1 can be used as a side wall of the entrance/exit 11, and a soil layer excavation area for forming an entrance/exit staircase etc. In addition, since the passage section 5 provided on the outside of one of the pipe bodies 1 as described above is vertical, the construction area for setting the vertical passage section 5 is also very small. , it can be sufficiently constructed on a site of several tens of m ² to 100 m ² . Therefore, it can be freely adopted in general households and small and medium-sized businesses, and as mentioned above, it enables comfortable living for long periods of time, is quiet against noise when installed underground, and is also suitable for steel pipes, etc. The complete shielding of the pipe body creates a magnetically and radio-protected environment, making it an extremely useful facility for information equipment, computer equipment, etc. Furthermore, it is easy to construct and requires only a small amount of land. Achieve sufficient cost reduction.

``Effect of the invention'' Since the invention as explained above uses pipe bodies, the parts manufactured in the factory can be transported to the site by vehicles such as trucks, and construction can be carried out easily and within a short period of time. In addition, by using a structure in which such tube bodies are assembled in a cross-shaped manner, the rolling property of the tube bodies is prevented, and a stable setting against the foundation such as a stratum can be achieved. By making the pipe into a continuous living area or bedroom, and using the part of the pipe protruding from one pipe as a kitchen, toilet, entrance, etc., it is possible to store those facilities inside one pipe, such as a steel pipe. It is possible to provide an underground structure that can be used as a living space without being obstructed by the environment, and by providing a vertical passage in one pipe body, the entrance and exit provided in the other pipe body can be blocked in the event of an abnormality. Moreover, the adoption of such a vertical passage and the fact that the entrance is opened along the outer surface of one pipe body make it possible to enter and exit above ground even in cases where underground equipment is used as an entrance or evacuation site. The site area required for the setup, including the opening, can be significantly reduced, and the equipment can be freely adopted in general households and small and medium-sized businesses, and as mentioned above, the construction period and man-hours can be significantly reduced. In combination with this, it has the effect of achieving effective cost reduction, and is a device with great practical effects.
