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 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 Act. Also, for a reinforced concrete building, the details of the thickness and strength of the columns are detailed. The minimum standard is set.

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.

By the way, in such a conventional technique, an increase in the proportion of pillars as the number of floors increases means that the effective use area of the structure decreases, There has been a demand for the development of a pillarless structure that can eliminate pillars from objects.

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 wasted from the building. Had been released. In particular, due to recent global warming, a large amount of energy is wasted in cooling in the summer, and there is a situation where existing power generation equipment cannot keep up.

In view of the problems of the prior art as described above, the present inventor substantially reduces the number of columns supporting a hierarchical structure including a roof, floor, hierarchical members, etc., and effectively uses the area of the structure.
