FIXING STRUCTURE AND FIXING METHOD OF RESIN PAD FOR FENDER
To provide a fixing structure and a fixing method of resin pads for fenders, which can detachably fix a resin pad onto a shock-receiving plate of a fender and can further inhibit chronological loosening of the fixing state.SOLUTION: An inner peripheral surface 6 of a pad-fixing hole 5 that passes through a resin pad 4 is designed to have a diameter-increasing part in which an inner diameter increases at a front position. The resin pad 4 is arranged on a front face 3a of a shock-receiving plate 3 with the pad-fixing hole 5 being positioned at an installation hole 3b of the shock-receiving plate 3. A fixing bolt 7 is inserted through the pad-fixing hole 5 and the installation hole 3b. A peripheral marginal part 8b around an insertion hole 8a of an elastic washer 8 through which the fixing bolt 7 is inserted is made to contact a head 7a of the fixing bolt 7 and the front face 3a of the shock-receiving plate 3 to be interposed therebetween, so as to be fixed to the shock-receiving plate 3. Said fixing arrangement causes the elastic washer 8 to elastically deform so as to cause an outer peripheral part 8c rather than the peripheral marginal part 8b to consistently press a diameter-increasing part 6a against the front face 3a of the shock-receiving plate 3 to secure the resin pad 4 onto the front face 3a of the shock-receiving plate 3.SELECTED DRAWING: Figure 4
【課題】防舷材の受衝板に対して樹脂パッドを着脱自在に固定でき、固定状態の経時的な緩みを一段と抑制できる防舷材用樹脂パッドの固定構造および固定方法を提供する。【解決手段】樹脂パッド４を貫通するパッド取付穴５の内周面６を、より前方位置に内径をより大きくした拡径部を有する仕様にして、樹脂パッド４を受衝板３の前面３ａに配置し、パッド取付穴５を受衝板３の設置穴３ｂに位置決めし、固定ボルト７をパッド取付穴５及び設置穴３ｂに挿入して、固定ボルト７に挿通させた弾性ワッシャ８の挿通穴８ａの周縁部８ｂを固定ボルト７の頭部７ａ及び受衝板３の前面３ａに接触させて両者に挟持させた状態にして受衝板３に固定し、この固定によって弾性ワッシャ８を弾性変形させて、周縁部８ｂよりも外周側部分８ｃによって拡径部６ａを受衝板３の前面３ａに向かって常時押圧して樹脂パッド４を受衝板３の前面３ａに圧着させる。【選択図】図４
