The beams 9 are provided in parallel in one direction or crossed in two directions. The beam shape of the beam 9 is formed by appropriately bending the bottom steel plate 5a or by welding a plurality of steel plates into a beam shape.
Shear connectors 8 are protruded from the inside at predetermined intervals. Also in this example, the lower end streaks are omitted because the bottom steel plate 5a functions as the lower end streaks.

化と工期の大幅な短縮化を図ることができる。The present invention has the above-described structure,
In particular, the upper foundation of the upper building is constructed by casting concrete into a steel plate formwork consisting of a bottom plate and side plates placed around it, so assembling and dismantling work like the former formwork Since this can be omitted, it is possible to greatly reduce labor in on-site construction and greatly shorten the construction period.
【００１６】また、底鋼板が下端筋を兼ねることから下
端筋を省略できるため、鉄筋の節約による経済施工も図

略することにより、経済性をより高めることができる。Also, since the bottom steel plate also serves as the lower end bar, the lower end bar can be omitted, so that economical construction can be achieved by saving the reinforcing bar. At that time, by installing the upper steel plate and omitting the upper end streaks, the economic efficiency can be further improved.

働き、また底鋼板と側鋼板の座屈も防止できる。Further, since the shear connectors are provided at predetermined intervals on the inner side of the bottom steel plate and the side steel plate so as to integrate with the concrete frame, the bottom steel plate and the side steel plate function as reinforcing bars, and the bottom steel plate and the side steel plate are connected to each other. Buckling of the side steel plate can also be prevented.
【００１８】さらに、上部基礎の下端面が鋼製で平坦な
ために、積層ゴム等の免震装置の取り付けも容易におこ
なうことができる。Further, since the lower end face of the upper foundation is made of steel and flat, it is possible to easily mount a seismic isolation device such as a laminated rubber.
