The invention discloses a fully-prefabricated assembly type rail structure on a steel truss beam, and the fully-prefabricated assembly type rail structure is arranged on the steel truss beam (1). Thefully-prefabricated assembly type rail structure comprises a steel rail bearing mechanism and a fixed connecting mechanism, wherein the steel rail bearing mechanism comprises a sleeper slab (3) whichis arranged on the top of the steel truss beam (1); the two ends of the sleeper slab (3) are equipped with sleeper slab mounting holes (15); the bottom end surface of the sleeper slab (3) is equippedwith an isolating buffer cushion plate (2); the fixed connecting mechanism comprises a hollow sleeve (4), and an iron cushion plate (10) is arranged inside a reserved hole (13) of the isolating buffercushion plate; and the top of a high-strength bolt (9) is arranged on the top end surface of the sleeper slab (3). The fully-prefabricated assembly type rail structure can realize higher prefabricating degree, facilitates quick and convenient field construction; and meanwhile, in aspect of maintenance, a prefabricated component is used more conveniently, so that needed maintenance time is reduced.
Description
technical field [0001] Embodiments of the present invention belong to the technical field of railway track structures, and more specifically, relate to a fully prefabricated assembled track structure on a steel truss girder. Background technique [0002] Steel truss structure is the main structural type commonly used in modern railway bridges. It has outstanding advantages such as simple structure, convenient construction, and strong bearing capacity. It is widely used in the construction of ordinary speed railways, high-speed railways and intercity railways. At present, the commonly used track structures of railway steel truss beams at home and abroad include wooden sleeper open deck track, ballasted track, synthetic resin sleeper track and sleeper slab track. [0003] The traditional open-deck railway steel truss girder bridge adopts a longitudinal and horizontal girder system. The steel rails are connected to the sleepers through fastener spikes, and the sleepers are conn...
