PROBLEM TO BE SOLVED: To provide brace connection fittings that eliminate the need for accurate strength calculation in the selection of brace materials, and further are not disengaged from a fixed portion such as a ceiling slab or a ceiling base material even when a large-scale earthquake exceeding assumption occurs.SOLUTION: Brace connection fittings 1 include: a fixing member 10 fixed to a main frame; a turning member 20 pivoted by the fixing member 10, and formed of a first through-hole 21 of a predetermined inner diameter in the middle position and a second through-hole 22 perpendicular to the first through-hole 21 with the diameter smaller than that of the first through-hole 21; a connecting member 30 formed of a third through-hole 33 of the same diameter as the second through-hole 22 in a predetermined position of an insertion part 31 inserted into the first through-hole 21; and a fuse pin 40 inserted and fixed into both of the second through-hole 22 and the third through-hole 33 while an insertion part 31 is inserted into the first through-hole 21. The fuse pin 40 is configured to be broken by the force working from the connecting member 30.SELECTED DRAWING: Figure 2
【課題】ブレース材の選定時に精密な強度計算を必要とせず、しかも想定を超えるような大規模地震が発生した場合でも天井スラブや天井下地材などの固定部分からは離脱しないブレース連結金具を提供する。【解決手段】ブレース連結金具１は、躯体などに固定される固定部材１０と、固定部材１０によって軸支され、その中央位置に所定内径の第１の貫通孔２１と第１の貫通孔２１よりも小径で第１の貫通孔２１と直交する第２の貫通孔２２とが形成される回動部材２０と、第１の貫通孔２１に挿入される挿入部３１の所定位置に第２の貫通孔２２と同径の第３の貫通孔３３が形成される連結部材３０と、挿入部３１が第１の貫通孔２１に挿入された状態で第２の貫通孔２２と第３の貫通孔３３との双方に挿入して固定されるヒューズピン４０とを備え、連結部材３０から作用する力でヒューズピン４０が破断する構成である。【選択図】図２
