Expansion-joint-crossing uninterrupted paving structure for bridge and mounting method of expansion-joint-crossing uninterrupted paving structure
The invention discloses an expansion joint spanning uninterrupted paving structure for a bridge. The expansion joint spanning uninterrupted paving structure comprises an anti-shearing area and non-anti-shearing areas, wherein the anti-shearing area is located in the middle of the top face of a single-connection main beam in the bridge direction, and the non-anti-shearing areas are located on the two sides of the anti-shearing area. A first connecting piece is arranged on the anti-shearing area, and the first connecting piece is of an anti-shearing type; a second connecting piece is arranged on the non-shear-resistant area in the bridge direction, and the second connecting piece is in an anti-pulling and non-shear-resistant mode. A first pavement layer is arranged on the top surface of the single-connection main beam, and the first pavement layer completely covers the first connecting piece and the second connecting piece; a second pavement layer is further arranged between the top surface of the single-connection main beam and the first pavement layer in a non-shear-resistant area of the top surface of the single-connection main beam, and the second pavement layer is a non-binding material layer; the first pavement layer and the second pavement layer which are arranged on the adjacent single-connection main beams and span the expansion joint are continuous and uninterrupted. According to the invention, the seamless long-connection bridge floor is realized, the adjacent main beams are spanned through the pavement structure made of the cement-based material, the intermittent design of a mechanical expansion joint is avoided, the driving safety is ensured for a long time, and the driving comfort is improved.
本发明公开了一种桥梁用跨伸缩缝的不间断铺装结构，其包括位于单联主梁顶面顺桥向的中部的抗剪区和位于抗剪区两侧的非抗剪区；抗剪区上设置有第一连接件，第一连接件为抗剪式；非抗剪区上顺桥方向设置有第二连接件，第二连接件为抗拔不抗剪式；单联主梁顶面设有第一铺装层，第一铺装层将第一连接件和第二连接件完全覆盖；在单联主梁顶面的非抗剪区，在单联主梁顶面与第一铺装层之间还设有第二铺装层，第二铺装层为无粘结材料层；相邻单联主梁跨伸缩缝上的第一、第二铺装层连续不间断。本发明实现了长联桥面的无接缝，通过水泥基材料的铺装结构跨越相邻主梁，避免了机械式伸缩缝的间断式设计，持久保障行车安全，提升行车舒适性。
