点があつた。 The conventional foundation for this type of building is a series of concrete cast in-situ around the entire perimeter of the building to be constructed. In other words, in the past, concrete was poured on-site in addition to the foundation part on which the column legs rest, as well as the part in between. However, the area in between is not a major part in terms of structural durability, and does not necessarily require sufficient strength and thickness to support the building's load. This method had the drawbacks of requiring extra concrete and requiring a lot of effort and time for foundation construction.

とする。 The present invention solves these drawbacks. After concrete foundations for mounting and fixing column legs are poured on-site at predetermined intervals, the concrete foundations are placed between the outer surfaces of adjacent concrete foundations. It is characterized by attaching a horizontally long precast concrete panel to it using anchor bolts buried therein.
以下に本発明の実施例を図面を参照して詳述す
