Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure which basically does not require a pillar raised from the ground, and more particularly to an underground structure which is dug directly from the ground to the underground.

[0002]

2. Description of the Related Art In a conventional structure, a hierarchical structure including a roof, a floor, and a hierarchical member is supported by a plurality of pillars which stand vertically on the ground. Therefore, as the number of floors increases, such as the second floor and the third floor, the weight that each pillar must support increases.

Therefore, in the case of a wooden building, as a general rule, four or more stories are prohibited by the Building Standards Law, and the reinforced concrete building is also detailed in terms of column thickness and strength. It sets minimum standards.

In the case of a building with a basement floor, the weight of the floor above the floor of the lowest floor is supported by columns, which is the same as the structure built on the ground.

[0005]

The increase in the proportion of pillars as the number of floors increases means that the effective use area of the structure decreases, and the pillars can be eliminated from the structure. There was a demand for the development of the structure.

Further, the energy required for heating and cooling a building has become a social problem, but in a building built on the ground, four laps are exposed to the outside air, so a huge amount of energy is wastefully released from the building. It had been. In particular, due to recent global warming, a large amount of energy is consumed for cooling in the summer, and there are cases where existing power generation facilities cannot keep up.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art.
It is an object of the present invention to provide an underground structure that can reduce the number of columns that support a hierarchical structure such as floors and hierarchical members.

The underground structure of the present invention includes a peripheral wall portion forming a mortar-shaped space; a plurality of support members provided around the mortar-shaped space so as to be flush with each other;
A beam whose ends are supported by a plurality of supporting means, and a hierarchical structure having a hierarchical portion arranged at a central portion at least a predetermined distance from the peripheral wall portion.

In a preferred embodiment of the present invention, a plurality of supporting members are provided at different positions in the height direction, and a hierarchical structure is provided so as to form a plurality of hierarchies. A multi-layered underground structure is provided.

In another preferred embodiment of the present invention, a base-isolated underground structure which protects the hierarchical structure at the time of an earthquake is provided because each support member and the beam of the hierarchical structure are not tightly connected. Provided.

[0011]

In the underground structure of the present invention, the plurality of support members are
It is provided so as to be flush with the circumference of the mortar-shaped space. The hierarchical structure is supported by the plurality of support members.

In an underground structure having a multi-layer structure, each hierarchical structure is supported by a plurality of support members provided so as to have the same plane height for supporting each structure. Therefore,
Each hierarchical structure is supported independently of each other, and it is sufficient that each support member has sufficient strength to support the hierarchical structure.

The layer portion arranged in the central portion of the layer structure is provided at least at a predetermined distance from the peripheral wall portion. If this interval is set large, sunlight can be sufficiently supplied to the lower floors.

Further, by increasing the angle of the peripheral wall portion with respect to the horizontal, it is possible to increase the number of layers per plane width. Further, by setting the angle of the peripheral wall portion with respect to the horizontal to be small, it is possible to sufficiently supply sunlight to the lower layer.

The underground structure of the present invention will be described in detail below with reference to the drawings.

1 to 3 are a perspective view, a plan view and a vertical sectional view of an embodiment of an underground structure according to the present invention.

An underground structure 10 according to the present invention is roughly composed of a peripheral wall 12 forming a mortar-shaped space and a plurality of support members 1 provided on the peripheral wall 12 so as to be flush with each other.
4 and a hierarchical structure 16 supported by a plurality of support members 14.

In the figure, GL represents the ground, and the overall size of the underground structure 10 is about 40 m in diameter and about 20 m in depth at the level of the ground GL.

In the illustrated embodiment, the underground structure 10 has six
Although it has a layered structure, it is needless to say that it is not limited to this, and one or more layers may be used. The height of each layer can be the same or different. The method of use and the way of division in each layer are arbitrary.

As best shown in FIG. 3, the peripheral wall 12 is formed by digging downward from the ground GL in a mortar shape. The angle of the peripheral wall 12 with respect to the horizontal can be arbitrarily selected, but if it is made large, the number of floors per plane width can be increased, and conversely, if it is made small, a lot of sunlight is supplied to the lower floors. You can also

The planar shape of the peripheral wall 12 can be various shapes other than the regular dodecagon as shown in FIG. FIG. 4A to FIG. 4D show an example of the case where the planar shape is a circle, a quadrangle, an ellipse, and a general water drop shape. Further, the vertical cross-sectional shape of the peripheral wall 12 is not only a straight sloped surface with a concrete exposed finish as shown in FIG. 2, but also an arc shape in which the slope becomes gentler as it goes deeper, or trees and flowers are gradually formed in a field. Can be planted.

The hierarchical structure 16 includes beams 18 extending radially.
And a hierarchical plate 20 supported on the beam 18. The floor plate 20 serves as a roof of an underground structure in the uppermost floor, and in the basement 1st floor, the basement 2nd floor ..., the floor of the basement 1st floor and the ceiling of the basement 2nd floor, and the floor of the basement 2nd floor, respectively. Ceiling on the 3rd basement floor. In the illustrated embodiment, the layer plate 20 serves as the floor surface of each layer and the ceiling of the layer below, but of course it can be a separate member. A space having a predetermined interval is formed in each layer between the outer edge of the hierarchical plate 20 and the peripheral wall 12.
If this space is large, much sunlight will be supplied to the lower floors.

FIG. 5 shows a supporting member 1 for supporting the ends of the beam 18.

The support member 14 includes a horizontal surface 14a supporting the lower surface of the end of the beam 18 and a horizontal surface 14a formed by moving the beam 18 left and right.
It has a pair of vertical surfaces 14b and 14b for preventing the vertical surfaces 14b and 14b from coming off. The abutting surface 14c sandwiched between the pair of vertical surfaces 14b and 14b is adapted to abut the end surface of the beam 18, whereby the beam 18, and thus the hierarchical structure 16 is contacted.
Are prevented from moving in the longitudinal direction of the beam 18.

In the preferred embodiment shown, an isolation cushion 22 is interposed between the beam 18 and the support member 14 to protect the hierarchical structure 16 during an earthquake. There is.

The support members 14 are fixed to the peripheral wall 12 so as to have the same plane height and at equal intervals by various methods. In the illustrated preferred embodiment, the peripheral wall 12 is provided with a recess 12a for the support member 14, the support member 14 is fitted into the recess 12a, and both are fixed by a conventionally known conventional means. There is.

The feature of the present invention is that the hierarchical structure 16 is the peripheral wall 1.
2 is supported by a plurality of support members 14 provided so as to have the same plane height, so that it is not necessary to support columns by principle in each layer. However, when the hierarchical structure 16 has a large diameter as in the illustrated embodiment, it is possible to supplementarily support the central portion. That is, in the illustrated preferred embodiment, the underground structure 10 has an elevator facility 2 at the center thereof.

Columns that can support the vicinity of the central portion of the layered structure 16 of each layer can be installed around the.

Underground structure 10 constructed in this way
Has a feature that it is not easily affected by temperature changes on the ground because the space used for the structure is underground. Therefore, even if the temperature in summer rises due to global warming, the underground structure is not affected by it, and the energy required for cooling can be reduced. Also, in winter heating, since the underground structure itself is warmed by geothermal heat, the energy required for heating can be reduced.

Furthermore, the ground surface can be used as a playground, a park, a parking lot, etc., and the underground structure is substantially isolated from the surrounding sound, so that it can be used in public buildings such as hospitals, libraries and schools. It is also perfect for
