ANCHOR BOLT FIXTURE FOR WOODEN COLUMN BASE FITTING AND WOODEN COLUMN BASE STRUCTURE USING THE SAME
PROBLEM TO BE SOLVED: To allow forming of a bolt insertion hole of a base plate as large diameter as possible, and to surely mount an anchor bolt fixture without interfering to a side face of a wooden column base fitting even when providing an anchor bolt in the maximum eccentric position.SOLUTION: A wooden column base fitting 2 where a wooden column 3 is mounted to a top face part 23 and an anchor bolt 4 where one end part thereof is projected from a top face of a base 5 are fixed by an anchor bolt fixture 1 for wooden column base fitting. The anchor bolt fixture 1 for wooden column base fitting comprises: a crescent-shaped outer ring 11 and a crescent-shaped inner ring 12 in a plan view; and a lower washer 14 and an upper washer 13 placed on the outer ring 11 and the inner ring 12. The lower washer 14 has a lower washer eccentric hole 14a larger than an outer diameter R4 of the anchor bolt 4, the lower washer eccentric hole 14a setting a position 14y that is eccentric by an eccentric distance L4, as a center, the eccentric distance L4 obtained by subtracting only the half of the outer diameter R4 of the anchor bolt 4 from a half of an amount adding a radius r21a of a bolt insertion hole 21a and a half of an outer diameter R4 of the anchor bolt 4 from a center 14x of the lower washer 14.SELECTED DRAWING: Figure 1
【課題】ベースプレートのボルト挿通孔を出来る限り大きな径で形成させることができると共に、アンカーボルトが最大に偏心した位置に設けられても木造柱脚金物の側面に干渉することなく、アンカーボルト固定金具を確実に取付ける。【解決手段】木質柱３が上面部２３に取付けられる木造柱脚金物２と、基礎５上面から一端部が突出したアンカーボルト４との固定に使用されるもので、平面視、三日月形状の外リング１１および内リング１２と、それら外リング１１および内リング１２の上に設置される下座金１４および上座金１３とを備え、下座金１４には、その中心１４ｘからボルト挿通孔２１ａの半径ｒ２１ａとアンカーボルト４の外径Ｒ４の１／２とを加算した値の１／２からアンカーボルト４の外径Ｒ４の１／２だけを減算した偏心距離Ｌ４だけ偏心した位置１４ｙを中心とするアンカーボルト４の外径Ｒ４よりも大きな下座金偏心孔１４ａを有する。【選択図】図１
