Japanese Patent JP7093562
Kind Code:
B2
Abstract:
To provide column base hardware which is able to absorb a positional error of an anchor bolt, has high stiffness against a horizontal load, is able to embody enhancement for earthquake resistance, and the like.SOLUTION: Column base hardware 11 includes a lower plate 21 to be loaded on a pedestal 81, and further separately uses seat plates (31 and the like). On the seat plates (31 and the like), a shaft hole 39 in a long hole shape is provided through which an anchor bolt 83 passes, and the two seat plates (31 and the like) are inserted into one anchor bolt 83 in a state that the shaft holes 39 are orthogonal to each other. Moreover, on the lower plate 21, housing grooves 23 and 24 in which the seat plates (31 and the like) fit without being loosened, and an opening 22 is provided through which the anchor bolt 83 passes. Furthermore, the plurality of types of seat plates (31 and the like) are prepared where the shaft holes 39 are differently positioned. When fitting the seat plates (31 and the like) corresponding to a positional error of the anchor bolt 83 into the housing grooves 23 and 24, the column base hardware 11 and the anchor bolt 83 are bound by contact between vertical planes but not by friction so as to obtain high stiffness for enhancing earthquake resistance.SELECTED DRAWING: Figure 1
