Easy-to-replace rotating shaft type bridge expansion joint device
The invention belongs to the technical field of bridge expansion joint devices and relates to an easy-to-replace rotating shaft type bridge expansion joint device. The easy-to-replace rotating shaft type bridge expansion joint device comprises a reserved notch and an expansion joint; expansion joint profile steel is arranged in the reserved notch; the expansion joint profile steel comprises two upper portions and two lower portions; the upper portions and lower portions are arranged in a mirror image mode relative to the expansion joint; a pin shaft hole hinged to one end of each upper portionis formed in the top of the corresponding lower portion; a clamping groove connected with a rubber waterstop in a clamped mode is formed in the side wall, close to the expansion joint, of each lowerportion; one end of each upper portion is hinged to the top of the corresponding lower portion; the other end of each upper portion is used for pressing the two ends of the rubber waterstop; the side,away from the expansion joint, of each lower portion is connected with one end of an anchoring steel bar; and the other end of the anchoring steel bar is connected with an embedded steel bar arrangedin the reserved notch. The easy-to-replace rotating shaft type bridge expansion joint device is easy to construct, and is convenient to replace after being damaged, and therefore, maintenance and replacement difficulty is greatly reduced; the steel structure is not prone to damage due to the influence of physical and chemical environments, and therefore, the service life of the device is longer.
本发明涉及桥梁伸缩缝装置技术领域，尤其涉及一种易更换的转轴式桥梁伸缩缝装置，包括预留槽口、伸缩缝，所述预留槽口内设有伸缩缝型钢，所述伸缩缝型钢包括关于伸缩缝镜像设置的两个上部和下部，其顶部设有用于与所述上部一端铰接的销轴孔，所述下部靠近所述伸缩缝的一侧壁上设有用于与橡胶止水带卡接的卡槽，所述上部的一端与所述下部的顶部铰接，另一端用于压紧所述橡胶止水带的两端；所述下部远离所述伸缩缝的一侧与锚固钢筋的一端相连，所述锚固钢筋的另一端与设置于预留槽口内的预埋钢筋相连。本发明施工简易，而且损坏后方便更换，极大地减小了维修、更换的难度，且钢制的结构不易受物理化学环境的影响而损坏，使用寿命更长。
