PURPOSE: To simplify the structure, reduce the production cost, and simplify the execution by rationalizing the opened faces of an H-steel with bent reinforced plates respectively, integrally providing a stationary plate on the upper face as a split foundation body, and integrating surrounding plates having the same shape into a surrounding plate body constituted of a square cavity inserted with the H-steel of the split foundation body and expansion sections.
CONSTITUTION: Bent reinforced plates bent perpendicularly at both ends are integrally welded to both opened faces of an H-steel. A stationary plate is welded to the H-steel integrated with the bent reinforced plates to form a split foundation body B. Bolt insertion holes are bored on surrounding plates having the same shape, two surrounding plates are combined to form a surrounding plate body C. Only the surrounding plate body C is installed in advance, then the H-steel of the split foundation body B is inserted into the square cavity of the surrounding plate body C until the bent reinforced plates are brought into contact with the upper side of the surrounding plate body C. The transportation cost is reduced, and the installation cost can be sharply reduced due to split installation.
