PROBLEM TO BE SOLVED: To provide a base plate for an exposed-type steel column base, which can adapt even to an increase in the size of a steel column by enhancing flexural rigidity without increasing the plate thickness of a base plate body portion. SOLUTION: In this flat plate-like base plate 1, the base plate body portion 2 is fixed to a lower end of the steel column 4 on a top surface side; anchor bolts 6 protruding from foundation concrete 5 are inserted through a plurality of bolt insertion holes which are provided in the column outside portion 2b of the base plate body portion 2, and tightened with nuts 7 from above, respectively, so that the steel column 4 can be fixed to the foundation concrete 5. A plurality of plate-like portions 3 are erected astride a virtual borderline on the undersurface side of the base plate body portion 2, while leaving spaces among one another along the virtual borderline on which a fixing portion of the steel column 4 is projected. Thus, the column outside portion 2b of the base plate body portion 2, in which the anchor bolt 6 is arranged, is effectively reinforced. COPYRIGHT: (C)2010,JPO&INPIT |
