Novel bolt-free comb plate bridge expansion system capable of being rapidly replaced and construction method
The invention discloses a novel bolt-free comb plate bridge expansion system capable of being rapidly replaced and a construction method. The system comprises an embedded anchoring assembly, a toothed plate assembly and a damping plate which are arranged on two adjacent beam bodies from top to bottom. The toothed plate assemblies on the beam bodies on the two sides are symmetrically arranged in a crossed mode and are of a double-tooth seam crossing structure. The pre-embedded anchoring assembly and the toothed plate assembly are fixed by matching a wedge-shaped limiting block with a limiting bolt; the embedded anchoring assembly comprises a wedge-shaped plate, middle profile steel and end profile steel, wherein the middle profile steel and the end profile steel are arranged on one side of the wedge-shaped plate at intervals from near to far. The toothed plate assembly comprises an end plate matched with the wedge-shaped plate and a plurality of seam crossing toothed plates arranged on the end plate. A wedge-shaped tensile block is arranged at the bottom of the tooth root of the toothed plate assembly, an elastic piece is arranged at the bottom of the seam crossing toothed plate, the wedge-shaped tensile block is matched with the middle profile steel, and the elastic piece is matched with the end profile steel, so that vertical displacement of the toothed plate assembly is limited jointly, and then jumping prevention is achieved. No bolt is assembled on the surface of the toothed plate, so that the driving safety problem caused by bolt loosening is avoided.
本发明公开了一种可快速更换的新型无螺栓梳齿板桥梁伸缩系统及施工方法，系统包括分别由上而下设于相邻两个梁体上的预埋锚固组件、齿板组件、减震板；两侧梁体上所述齿板组件交叉对称布置，并呈双齿跨缝结构；预埋锚固组件与齿板组件之间采用楔形限位块配合限位螺栓固定；预埋锚固组件包括楔形板，由近及远间隔设于楔形板一侧的中间型钢和端部型钢；齿板组件包括与楔形板相适配的端头板和设于端头板上的若干跨缝齿板；齿板组件的齿根底部设有楔形抗拉块，跨缝齿板的底部设有弹性件，通过楔形抗拉块与中部型钢的配合、弹性件与端部型钢配合，共同限制齿板组件的竖向位移进而实现防跳；通过齿板表面无螺栓装配，避免螺栓松动引起的行车安全问题。
