ABUTTED-TYPE EXPANSION/CONTRACTION DEVICE FOR ROAD BRIDGE, AND CONSTRUCTION AND REPAIR METHODS THEREFOR
PROBLEM TO BE SOLVED: To provide an abutted-type expansion/contraction device suited for a road bridge with a small expansion/contraction amount.SOLUTION: An abutted-type expansion/contraction device for a road bridge comprises: a pair of expansion/contraction joints (J1) (J2) that almost form an L-shape overall with face plates (2a) (2b) erected to face each other on both sides of a joint of a road bridge and having a height (H) corresponding to a thickness (T) of an asphalt pavement (A), and flat base plates (3a) (3b) that integrally extend toward rear directions that are separated from each other, from a bottom edge of the erected face plates; and an elastic water-stop layer (8) filled and fixed between the erected face plates in front and rear that face each other of the two expansion/contraction joints. The base plates of the two expansion/contraction joints are fitted and fixed on a surface of a bridge abutment (22) and a bridge girder (1), or of bridge girders, with a hanging elastic water-stop sheet (17) that covers the joint of the road bridge in between. At the same time, the asphalt pavement (A) is laid behind the erected face plates of the two expansion/contraction joints as a backfill for making an integral structure, at a thickness that almost equals the height of the erected face plates.
【課題】伸縮量の小さな道路橋にふさわしい突き合わせ型の伸縮装置を提供する。【解決手段】アスファルト舗装（Ａ）の厚み（Ｔ）に対応する背丈（Ｈ）として、道路橋の継ぎ目を挟む対向状態に起立するフェイスプレート（２ａ）（２ｂ）と、その起立フェイスプレートの下端部から互いに離反する背後方向へ一体的に張り出すフラットなベースプレート（３ａ）（３ｂ）とから全体的なほぼＬ字形をなす一対の伸縮継手（Ｊ１）（Ｊ２）と、その両伸縮継手における起立フェイスプレート同士の向かい合う前後相互間へ充填状態に固着された弾性止水層（８）とを備え、両伸縮継手のベースプレートを橋台（２２）と橋桁（１）又は橋桁同士の表面へ、その道路橋の継ぎ目を覆う吊り下げ状態の弾性止水シート（１７）を介して、各々取り付け固定すると共に、両伸縮継手における起立フェイスプレートの背後へ、アスファルト舗装（Ａ）をその起立フェイスプレートの背丈とほぼ同じ厚みだけ裏込め一体化した。【選択図】図４
