LINING PLATE FIXING STRUCTURE
To provide a lining plate fixing structure capable of extremely easily and surely fixing a lining plate on a receiving beam using one type of rotation jig and releasing the fixing.SOLUTION: A fixing structure comprises: a fixing bolt 3 arranged through a bottom plate 2a of a lining plate 2 laid on a receiving beam 1; a fastening metal 4 attached to a bolt shaft 3a of the fixing bolt 3 protruding below the bottom plate 2a; and a tightening nut 11 attached to the bolt shaft 3a of the fixing bolt 3 protruding above the bottom plate 2a. The fastening metal 4 rotates together with the fixing bolt 3 by tightening the tightening nut 11, and hooks on an upper flange 1a of the receiving beam 1. A reaction force receiving part 4a of the fastening metal 4 in contact with the bottom plate 2a is rotated upward around the fulcrum and attached so as to sandwich the upper flange 1a. A first recessed groove part 7a is provided at a position where the reaction force receiving part 4a of the bottom plate 2a abuts, and prevents the fastening metal 4 from rotating by engaging an upper end part of the reaction force receiving part 4a.SELECTED DRAWING: Figure 1
【課題】受け梁の上に覆工板を一種類の回転治具を用いてきわめて容易にかつ確実に固定し、固定を解除できる覆工板取付け構造を提供する。【解決手段】受け梁1の上に敷設された覆工板2の下面板2aを貫通して配置された固定ボルト3と、下面板2aの下側に突出した固定ボルト3のボルト軸部3aに取り付けられた締結金物4と、下面板2aの上側に突出した固定ボルト3のボルト軸部3aに取り付けられた締付けナット11とから構成する。締結金物4は、締付けナット11の締付けにより固定ボルト3と共に回転して受け梁1の上フランジ1aに掛止すると共に、下面板2aに当接した締結金物4の反力受け部4aを支点に上方に回転して上フランジ1aを挟み込むように取り付ける。下面板2aの反力受け部4aが当接する位置に、反力受け部4aの上端部が係合することにより締結金物4の回転を阻止する第一凹溝部7aを設ける。【選択図】図１
