EXPANSION JOINT FLOOR
To provide an expansion joint floor capable of effectively absorbing swing between skeletons due to an earthquake and the like and capable of resisting heavy load.SOLUTION: An expansion joint floor 1 joining skeletons neighboring via a gap 4 comprises: a plurality of slide beams 5 diagonally disposed between one skeleton 2 and the other skeleton 3 and slidably supported; a plurality of floor joists 6; and a center maintaining mechanism 9 comprising a plurality of pantograph-shaped link mechanisms. A central floor plate whose central part is pivotally supported and fastened by a floor joist 6C positioned in a central part of the gap 4 between the skeletons and an end portion floor plate which is positioned below the central floor plate and which overlaps with the central floor plate and can slide with each other are arranged. The pantograph-shaped link mechanisms are vertically disposed in a plurality of places below the slide beam 5 perpendicularly to the gap 4 between the skeletons. An upper part of the link mechanism is pivotally attached to a central part of the slide beam 5, and both end portions are pivotally supported on one skeleton 2 and the other skeleton 3 respectively.SELECTED DRAWING: Figure 1
【課題】地震などによる躯体間の揺れを効果的に吸収することができ、重荷重にも耐えることできるエキスパンションジョイント床を提供する。【解決手段】間隙４を介して隣接する躯体と躯体を接合するエキスパンションジョイント床１であって、一方の躯体２と他方の躯体３の間に斜めに配置され、スライド移動可能に支持された複数のスライドビーム５と、複数本の根太６と、複数のパンタグラフ状のリンク機構からなる中心維持機構９を備え、躯体間の間隙４の中央部に位置する根太６Ｃに中央部を支受、固着された中央床プレートと、中央床プレートの下方に位置して中央床と重なり合い互いにスライド可能な端部床プレートを配設し、パンタグラフ状のリンク機構をスライドビーム５の下方に躯体間の間隙４と直交させて竪方向に複数個所配置し、上部をスライドビーム５の中央部に枢着し且つ両端部をそれぞれ一方の躯体２および他方の躯体３に枢支してなる。【選択図】図１
