SOUND INSULATION PLATE FASTENER FOR SOUND PROOF WALL
PROBLEM TO BE SOLVED: To provide a plate spring type sound insulation plate fastener to fix the sound insulation plate of a sound proof wall, which can significantly improve load bearing with little change in a thickness of the plate spring.SOLUTION: For a fastener, a first contact part 17, which is a part connecting a first horizontal side part 14 and a second horizontal side part 15, can contact to an inner surface of a first vertical side part 12, and a second contact part 18, which is placed between a part connecting the second horizontal side part 15 and a third horizontal side part 16 and the third horizontal side part 16, can contact to an inner surface of a second vertical side part 13. The second contact part 18 has an inclined side part 20, which inclines obliquely downward from the inner surface of the second vertical side part 13, at a position lower than the position where the second contact part 18 contacts to the inner surface of the second vertical side part 13. The second contact part 18 contacts with and slides on the inclined side part 20.
【課題】防音壁の遮音板を固定する板バネ式の遮音板留め金具において、板バネの厚さを殆ど変更することなく、耐荷重性を大幅に改善できる留め金具を提供する。【解決手段】留め金具は、第１横辺部１４と第２横辺部１５との接続部である第１接触部１７が第１縦辺部１２の内面に接触可能で、第２横辺部１５と第３横辺部１６との接続部から第３横辺部１６との間に設けられた第２接触部１８が第２縦辺部１３の内面に接触可能であり、第２接触部１８が第２縦辺部１３の内面に接触する位置よりも下方位置で、第２縦辺部１３の内面から斜め下方に向かって傾斜した傾斜辺部２０を備え、第２接触部１８が傾斜辺部２０に接触して滑るように構成されている。【選択図】図２
