EXPANSION DEVICE OF ROAD BRIDGE
PROBLEM TO BE SOLVED: To provide an expansion device of a road bridge applicable even when an expansion joint of the road bridge crosses at an acute angle with the vehicle advance direction, and capable of reducing installation cost by reducing work time such as welding.SOLUTION: An expansion device 1 installed between expansion joints D of crossing at an acute angle with the vehicle advance direction of a road bridge, comprises an expansion device body having a pair of comb-shaped face plates 20 mutually opposed in irregularity on a surface and a guide plate projected at a predetermined interval toward the outside from an outside surface of this expansion device body, and a base end part of the guide plate is installed so as to be orthogonal to the outside surface of the expansion device body, and a tip part of the guide plate is installed along the vehicle advance direction.SELECTED DRAWING: Figure 1
【課題】道路橋の伸縮目地が車両進行方向と鋭角に交差する場合であっても適用することができ、溶接等の作業時間を削減して設置コストを低減することができる道路橋の伸縮装置を提供する。【解決手段】道路橋の車両進行方向と鋭角に交差する伸縮目地Ｄ間に設置される伸縮装置１において、表面に互いに凹凸が対向する一対の櫛形状のフェイスプレート２０，を有する伸縮装置本体と、この伸縮装置本体の外側面から外側へ向け所定間隔をおいて突設される誘導板と、を備え、誘導板の基端部は、前記伸縮装置本体の外側面に直交するように取り付けられ、且つ、前記誘導板の先端部は、前記車両進行方向に沿って取り付けられている。【選択図】図１
