摘要： PURPOSE: To improve general purpose properties, to simplify installation to a floor, and to reduce the height and the installation area of a unit product by a method wherein a common base comprises a pair of angle steels the outer surfaces of which are situated facing each other; and a single steel sheet fixed to the upper edge parts of a pair of the angle steels in such a manner to cover the angle steels. CONSTITUTION: Formation of a common base A is such that a pair of angle steels 1 are arranged in such a state that outer surfaces thereof are positioned facing each other and a steel sheet 2 is welded to the upper end parts of the angle sheets 1 in such a manner to cover the angle steels 1 therewith. A bridging steel 3 to intercouple the angle steels 1 is arranged, and a notch part 2a is formed in the part, positioned facing a foundation bolt B, of the steel sheet 2. A pump P can be installed in the free position of the steel sheet 2. Mounting of the common base A on a floor F is effected by the floor F and the inner surface U of the angle steel 1 without using a washer. The angle steel 1 having size lower than the standard minimum size of a channel steel can be employed and height is also reduced. Further, since the projection outer shape areas of the steel sheet 2 and the angle steel 1 are the same as each other, an installation area can be reduced.
