Easy-to-replace bridge damping expansion joint device
The invention relates to the technical field of bridges, and especially relates to an easy-to-replace bridge damping expansion joint device. The device comprises a concrete pavement layer arranged ona bridge deck, a reinforcing mesh, a bridge expansion joint, a threaded steel pipe and an anchor bolt, and the inner wall of the threaded steel pipe is provided with an internal thread matched with anexternal thread on the anchor thread; a rubber waterstop, a damping rubber belt and a steel plate are sequentially laid on the upper surface of the concrete pavement layer, and through holes allowinga screw of the anchor bolt to penetrate through are formed in the rubber waterstop and the damping rubber belt; the steel plate is provided with a countersunk through hole used for allowing a nut atthe top of the anchor bolt to be inserted in, and the countersunk through hole is communicated with the through hole. The waterproof requirement of a bridge can be met, damaged expansion joints on anexisting bridge can be replaced conveniently and rapidly, and simple replacement of the bridge expansion joint device can be completed only by detaching the bolt and sequentially replacing all structures in the device during actual replacement operation.
本发明涉及桥梁技术领域，尤其涉及一种易更换的桥梁减震伸缩缝装置，包括设置在桥面上的混凝土铺装层、钢筋网、设桥梁伸缩缝、螺纹钢管以及锚固螺栓，所述螺纹钢管内壁设有与所述锚固螺纹上外螺纹相匹配的内螺纹；所述混凝土铺装层的上表面依次铺设有橡胶止水带、减震橡胶带和钢板，所述橡胶止水带、减震橡胶带上设有用于所述锚固螺栓的螺杆穿过的通孔；所述钢板上设有用于所述锚固螺栓顶部的螺帽插入的沉头通孔，所述沉头通孔与所述通孔连通。本发明能够满足桥梁防水要求并实现方便快捷的更换既有桥梁上已损坏的伸缩缝，实际更换操作时仅需拆除螺栓，依次替换装置内各结构来完成本专利桥梁伸缩缝装置的简易更换。
