PROBLEM TO BE SOLVED: To provide a bearing force variable type fixture capable of adjusting fixing force for a sound insulation plate built in a groove of a column by turning a bolt.SOLUTION: A bearing force variable type fixture comprises a channel-shaped part holding therebetween inner and outer surfaces of a flange forming a channel-shaped groove in which a sound insulation plate is built, and a bolt is inserted with a bolt hole provided to a channel-shaped part of a bearing force transmission member aligned with a bolt hole provided to the flange part of the column, and screwed in a nut prepared at an inner part of the channel-shaped part to install the bearing force transmission member. A reaction force transmission part is formed for pressing reaction force from a position where an extension part of an inner piece forming the channel-shaped part is close to a web of the column to an opposite surface of a sound insulation plate positioned in the groove of the column, a part beyond the reaction force transmission part is inverted toward a position that a tip of the bolt abuts to the contrary to form an input part that the tip of the bolt abuts on, and a part beyond the input part that the tip of the bolt abuts on is formed into a tension face part which is tensed abutting on a bearing face part in the middle of reaching the reaction transmission part by extending an inner piece of the channel-shaped part.SELECTED DRAWING: Figure 1 【課題】支柱の溝内へ建て入れた遮音板の固定力をボルトの回転操作により調整することが可能な支持力可変型固定金具を提供する。【解決手段】遮音板を建てた支柱のコ字形溝を形成するフランジの内外面を挟むコ字形状部を備え、ボルトは支持力伝達部材のコ字形状部に設けたボルト孔を支柱のフランジ部に設けたボルト孔と一致させて通し、コ字形状部の内側部に用意したナットへねじ込み支持力伝達部材の設置を行う。コ字形状部を形成する内側部片の延長部分が支柱のウエブへ接近した位置から、支柱の溝内に位置する遮音板の対向面に向かって押す反力伝達部が形成され、反力伝達部より先方の部分は、逆にボルトの先端が当接する位置に向かって反転されてボルトの先端が当接する入力部が形成され、ボルトの先端が当たる入力部より先方の部分はコ字形状部の内側部片を延長させて反力伝達部へ至る途中の支持面部に当接し突っ張る突っ張り面部に形成されている。【選択図】図１
