The invention relates to the technical field of bridge expansion joints, in particular to a bridge seamless expansion joint structure. A bridge seamless expansion joint structure comprises seat blocks, the two seat blocks are arranged left and right, arc-shaped grooves are formed in the opposite sides of the seat blocks, and the two ends of an arc-shaped piece are slidably connected to the two arc-shaped grooves respectively. The front side and the rear side of the seat block are both in threaded connection with a plurality of blocking screws, and the blocking screws block the side faces of the arc-shaped pieces. A supporting wheel is arranged on the lower side of the arc-shaped piece, the front end and the rear end of the supporting wheel are rotationally connected to the middles of the two transverse columns correspondingly, and the two ends of each transverse column are slidably connected to the two seat blocks correspondingly. The two ends of each transverse column are both fixedly provided with round pieces, the two ends of each transverse column are both sleeved with compression springs, and the compression springs are located between the seat blocks and the round pieces. And gaps can be avoided during stretching and retracting.
本发明涉及桥梁伸缩缝技术领域，更具体的说是一种桥梁无缝伸缩缝结构。一种桥梁无缝伸缩缝结构，包括座块，两个所述座块左右设置，所述座块的相对侧均设置有弧形槽，弧形片的两端分别滑动连接在两个弧形槽上。所述座块的前后两侧均螺纹连接有多个挡螺钉，挡螺钉挡在弧形片的侧面。所述弧形片的下侧设置有支撑轮，支撑轮的前后两端分别转动连接在两个横柱的中部，每个横柱的两端分别滑动连接在两个座块上。每个所述横柱的两端均固定有圆片，横柱的两端均套接有压缩弹簧，压缩弹簧位于座块和圆片之间。可以在伸缩时避免出现缝隙。
