How to design column base anchor structures, mounts, and column base anchor structures

摘要

PROBLEM TO BE SOLVED: To make it possible to judge at a manufacturing site whether or not a profile plate constituting a column base anchor structure is selected at the time of design. SOLUTION: A column base anchor structure 1 includes one profile plate selected from a plurality of profile plates whose specifications are defined by a standard, and a pedestal for supporting the one profile plate. The lower profile plate 31 has a pair of support portions 221 that support the lower profile plate 31, the lower profile plate 31 has a pair of supported portions 312 that are supported by the pair of support portions 221 and the standard is a pair of supported portions 312. The specifications of the lower profile plate 31 are determined so that the distance b at the inner end of the above is gradually increased, the specification is that the supported portion 312 distance b is the first distance, and the distance is 1 than the first distance. Includes a specification in which the second interval is one step larger and a third interval in which the interval is one step larger than the second interval, and the interval d at the inner end of the pair of support portions 221 is greater than or equal to the first interval. The distance c between the outer ends of the pair of support portions 221 is equal to or greater than the second interval and equal to or less than the third interval. [Selection diagram] Fig. 1
