To provide a wraparound prevention fence which can maintain a function as the handrail that can be safely grabbed as usual while preventing damages at earthquakes.SOLUTION: A wraparound prevention fence is installed on an escalator entrance comprising a floor structure in which an escalator-side floor part 20 formed on the entrance of an escalator 2 and a floor-side floor part 30 on a building frame 3 side arranged at an interval from the escalator side floor part 20 can be relatively displaced at earthquakes. The wraparound prevention fence includes a pair of columnar supports 41, 42 supported by each of the escalator-side floor part 20 and the floor-side floor part 30, a handrail frame 5 fixed to the upper end part of either one of the pair of columnar supports 41, 42, and a horizontal member 6 connected to the pair of columnar supports 41, 42 and extending horizontally. The horizontal member 6 is provided with a movable joint part 60 with a variable length at a longitudinal intermediate part.SELECTED DRAWING: Figure 1
【課題】地震時において、損傷を防止しつつ、平常時と同様に安心して掴むことができる手摺としての機能を維持できる。【解決手段】エスカレータ２の乗降部に形成されたエスカレータ側床部２０と、エスカレータ側床部２０から間隔をあけて配置される建物の躯体３側のフロア側床部３０と、が地震時に相対変位可能な床構造からなるエスカレータの乗降口に設けられ、エスカレータ側床部２０とフロア側床部３０のそれぞれに支持される一対の支柱４１、４２と、一対の支柱４１、４２のいずれか一方の上端部に固定される手摺フレーム５と、一対の支柱４１、４２同士に連結され、水平方向に延びる横架材６と、を備え、横架材６には、長さ方向中間部で長さ可変可能な可動継手部６０が設けられている構成の廻り込み防止柵を提供する。【選択図】図１
