NOISE PREVENTIVE FIXTURE OF GRATING
PROBLEM TO BE SOLVED: To bring about no difficulty when installing a grating, with noise and theft preventive effects, by resiliently attaching a resiliently attaching part on a sidewall of a groove edge recessed part by constant pressing force, regardless of any of the size of a clearance between an end plate of the grating and the sidewall of the groove edge recessed part, in a noise preventive fixture of the grating installed on the end plate of the grating by being pushed in from the lower side and having a plate spring-shaped resiliently attaching part when the grating is installed in a side recessed part of a side ditch.SOLUTION: A rubber elastic body 24 of a thickness corresponding to the size of a clearance, is installed on the inside of a fixture 21, and a resiliently attaching part 23 is always resiliently attached on a sidewall of a groove part recessed part 27 by constant pressing force.
【課題】グレーチングの端板に下側から押込んで装着され、グレーチングを側溝の側縁凹部に装着したとき、溝縁凹部の側壁に弾着する板バネ状の弾着部を備えたグレーチングの騒音防止用の固定金具において、グレーチングの端板と、溝縁凹部の側壁との間の隙間の大小の如何にかかわらず、弾着部が一定の押付力で溝縁凹部の側壁に弾着し、騒音及び盗難防止効果と共に、グレーチングを装着するときの困難性をもたらすことがないようにする。【解決手段】固定金具２１の内側に前記隙間の大きさに応じた厚みのゴム製の弾性体２４を取付け、弾着部２３を常に一定の押付力で溝部凹部２７の側壁に弾着させる。【選択図】図４
