METAL FITTING FOR ROOF
To provide a metal fitting for a roof allowing an acute bending by too-strong tightening to be prevented under simple visual observation and a quick attachment operation to be done in a simple and adequate tightening manner to exhibit no decrease of attachment strength and excellent workability.SOLUTION: A metal fitting for a roof of which a pair of opposite clamping parts 3 to each other is provided with a bend-shaped part 6 bulging outward allows an acute bending to be prevented through visual observation on required enough degree of tightening with a tightening bolt 4 by visually observing existence of termination of bending due to bending-reducing deformation of a bend-shaped part 6 when tightening and clamping an attachment part 1 of the roof from both sides of with a lower clamp part after moving and making the pair of opposite clamping parts 3 closer by tightening the tightening bolt 4.SELECTED DRAWING: Figure 2
【課題】簡易な目視で締め付け過ぎによるサバ折れ現象を防止でき、常に簡易にして適正な締め付け加減で瞬時に取付作業がおこなえ、取り付け強度が低下せず作業性にも優れた屋根用取付金具を提供する。【解決手段】対向挟持部３に外側に膨らんだ湾曲形状部６を設け、締め付けボルト４による締め付けによりこの対向挟持部３を接近可動させて下部の挟持部で屋根の取付部１を両側から締め付け挟持した際に、この湾曲形状部６はその湾曲度が減じるように変形しこの湾曲度の消失の有無を視認することで、締め付けボルト４による締め付けの必要十分度合が視認でき、サバ折れ現象を容易に防止できる、屋根用取付金具。【選択図】図２
