Bridge seamless expansion joint sliding groove device
The invention relates to the technical field of bridges, and particularly discloses a bridge seamless expansion joint sliding groove device which comprises a sliding groove base, a spring assembly, a sliding groove cushion block, an anchoring sliding support and an embedded steel plate. A strip-shaped arc-shaped groove is formed in the upper surface of the strip-shaped sliding groove base. The spring assembly is of a strip-shaped arc-shaped structure formed by sequentially connecting a plurality of arc-shaped springs arranged side by side end to end, and the spring assembly is placed in the arc-shaped groove in the length direction of the arc-shaped groove. The two sliding groove cushion blocks are symmetrically arranged on the two sides of the spring assembly. The upper end of the sliding groove cushion block abuts against the lower surface of the check block in the opening in the upper end of the arc-shaped groove. A ball is arranged at the lower end of the anchoring sliding support and supported on the spring assembly. The upper end of the anchoring sliding support is connected with the embedded steel plate. According to the bridge seamless expansion joint sliding groove device, vertical displacement of an elastic expansion body in a seamless expansion joint can be well limited, the elastic expansion body is prevented from arching and being higher than the road surface, and later maintenance is easy.
本发明涉及桥梁技术领域，具体公开一种桥梁无缝伸缩缝滑槽装置，包括滑槽底座、弹簧组件、滑槽垫块、锚固滑托和预埋钢板。条状的所述滑槽底座的上表面上具有条状弧形槽。所述弹簧组件是由若干段并列排列的弧形弹簧的首尾依次相连形成的条状弧形结构，其沿着所述弧形槽的长度方向放置在弧形槽内。两个所述滑槽垫块对称设置在所述弹簧组件的两侧。所述滑槽垫块的上端抵接在弧形槽的上端开口中挡块的下表面上。所述锚固滑托的下端具有圆球，该圆球支撑在所述弹簧组件上。所述锚固滑托的上端与所述预埋钢板连接。本发明的桥梁无缝伸缩缝滑槽装置不仅能够很好地限制无缝伸缩缝中的弹性伸缩体的竖向位移，防止其起拱高出路面，而且易于进行后期维修。
