The invention relates to the field of bridge expansion devices, in particular to an integral anchoring type multidirectional displacement bridge expansion device and method. The left side integral ribbed comb plate (2) and the right side integral ribbed comb plate (9) are located on the two sides of a bridge beam end expansion joint (18) and are formed by integrally cutting integrally-rolled door-shaped steel (14) or integrally-rolled pi-shaped steel (16) according to a certain curve line shape (15) and conducting secondary machining; round, arc-shaped or trapezoidal chamfers are arranged at the ends of the comb teeth of the left integral ribbed comb plate (2) and the right integral ribbed comb plate (9), and triangular or quarter-oval chamfers are arranged at the roots of the comb teeth of the left integral ribbed comb plate (2) and the right integral ribbed comb plate (9). And a displacement support (6) is arranged at the lower part of the right integral ribbed comb plate (9). The durability of the expansion device can be effectively improved, and the effects of reducing noise and adapting to the multi-directional displacement requirement of a bridge are achieved.
本发明涉及桥梁伸缩装置领域，尤其涉及一种整体锚固式多向变位桥梁伸缩装置和方法。包含位于桥梁梁端伸缩缝（18）两侧由整体轧制的门型钢（14）或整体轧制的π型钢（16）按一定曲线线形（15）整体切割并二次加工而成的左侧整体带肋梳齿板（2）和右侧整体带肋梳齿板（9）；左侧整体带肋梳齿板（2）和右侧整体带肋梳齿板（9）的梳齿端部应设置圆形、弧形或梯形倒角，梳齿根部应设置三角形或四分之一椭圆形倒角。右侧整体带肋梳齿板（9）下部设置变位支座（6），本发明能有效提高伸缩装置的耐久性能并起到降低噪音、适应桥梁多向变位需求的作用。
