一种高架桥结构上的连续延伸轨道。;本发明叙述一种欲用以被一桥体结构(1)所支撑之连续延伸轨道(5)，该桥体结构包括至少两桥段(4)及一用以支撑该等桥段(4)之负载结构，而该延伸轨道(5)包括：一连续厚板(50)，其系从该桥体(1)之一端延伸至另一端并欲坐落在该等桥段(4)之一上表面上；一抗摩擦层(55)，其系位于该连续厚板(50)下方，并欲做为一介于该桥段(4)的该上表面与该连续厚板(50)的该下表面之间的界面，而该抗摩擦层(55)界定该连续厚板(50)之一滑动平面；一跨越板(53)，其系位于该连续厚板(50)下方，其被安置成可从一桥段的一端延伸至另一直接相邻的桥段的端部；该延伸轨道(5)之特征在于：其包括至少一欲被固定至一桥段(4)上之抗举升装置(54)，其可用来限制该厚板(50)在一与该滑动平面垂直之方向N上的移动，同时提供该厚板(50)在该滑动平面上之移动自由度。; - an antifriction layer (55) situated beneath the continuous slab (50), intended to act as an interface between the upper surface of said segment (4) and the lower surface of the continuous slab (50), said antifriction layer (55) defining a slip plane for said continuous slab (50); - a crossing plate (53) situated beneath the continuous slab (50), positioned so as to extend from one end of a segment to the end of another directly adjacent segment; said running track (5) being characterized in that it comprises at least one anti-lift device (54) intended to be fixed to a segment (4), capable of limiting a movement of said slab (50) in a direction N perpendicular to the slip plane while providing for freedom of movement of said slab (50) on the slip plane. |
