[0005] Each component requirement will be described in detail. A so-called cloth foundation that supports the weight of a building and propagates it on the ground surface is composed of a horizontally extending flat base and a wall-shaped rising part integrally formed with the base, and a vertical section. The surface is formed in a substantially inverted T-shape.

[0006] The fabric foundation supports the weight of the building by the reaction force from the ground acting on the bottom surface of the base portion. Therefore, by forming the base portion of the part where the pillar of the building supporting the heavier weight than the other part is located to be wider than the other part, the vertical load transmitted from the pillar to the foundation is dispersed. Therefore, the load can be stably supported, and the overall design is balanced and rational.

When a pillar is located inside a foundation arranged in a rectangular frame along the outer periphery of a building in plan view, it extends in a direction perpendicular to this side from the middle of two different sides of the rectangular frame foundation. Extend the foundation to the location where the pillar is located, connect both foundations at the location where the pillar is located, and adopt a structure in which the base part of the location where the pillar is located is wider than other parts As a result, the vertical load transmitted from the column located inside the foundation to the foundation is dispersed and stably supported by the wide base portion. A foundation extending in a direction perpendicular to this side from the position is sufficient as a foundation from two directions, so that a balanced and rational design can be achieved as a whole.
