GROOVE COVER DEVICE
PROBLEM TO BE SOLVED: To provide a groove cover device which prevents that a groove space which is covered with a groove covering body arranged at one of two skeletons which adjoin each other via the groove space from above is exposed to the outside by an earthquake.SOLUTION: A groove cover device 10 includes: a telescopic structure 21 which has energization means 32, is constituted so as to be telescopic in a groove width direction X, connected a skeleton 13 at one end in the groove width direction X, and held by an energization force of the energization means 32 in an elongated state at a normal time; and a cover body 22 which has a plurality of plate-shaped members 91, and is rotatably connected with a pair of the adjacent plate-shaped members 91. The telescopic structure 21 has a support face whose dimension in the groove width direction X is increased and decreased accompanied by the elongation/contraction of a pantograph structure part 31 at its upper part, has a salient part 33 which is salient to a skeleton 12 side rather than the support face at its lower part, and in the cover body 22, the plate-shaped member 91 arranged at the skeleton 13 side nearest thereto is connected to the skeleton 13 side, and horizontally supported by the support face from below.
【課題】 溝空間を介して隣接する２つの躯体の一方の躯体に設けられた溝被覆体によって上方から覆われている溝空間が地震により外部に露出してしまうことを防止する溝カバー装置を提供する。【解決手段】 溝カバー装置１０は、付勢手段３２を備え、溝幅方向Ｘに伸縮可能に構成され、溝幅方向Ｘの一端部が躯体１３に連結されて、常時は付勢手段３２の付勢力によって伸張状態で保持される伸縮構造体２１と、複数の板状部材９１を備え、隣接する一対の板状部材９１を回動自在に連結されて成るカバー体２２とを含み、伸縮構造体２１は、その上部に、パンタグラフ構造部３１の伸縮に伴って溝幅方向Ｘの寸法が増減する支持面を有するとともに、その下部に、支持面よりも躯体１２側に突出して設けられる突出部３３を有し、カバー体２２は、最も躯体１３側に配置される板状部材９１が躯体１３側に連結され、支持面によって下方から水平状に支持される。【選択図】 図２
