Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of steel beam bridge decks, and in particular to a fastener structure for exposed deck tracks of steel beam bridges. Background Art
[0002] An open bridge deck generally refers to the deck of a railway steel bridge, and the load-bearing surface is composed of multiple steel beams. When laying railway tracks on the open bridge deck, ballast is generally not laid, but the sleepers are directly fixed to the steel beams with bolts and other components; the sleepers used in this track structure are generally wooden sleepers or composite (or synthetic) material sleepers; in order to improve the stability of the track structure, reduce the impact of the wheel and rail at the rail joints, and reduce track vibration and noise, existing railway tracks generally use seamless lines, that is, long rails are welded together, thereby greatly limiting the longitudinal deformation of the rails under the action of ambient temperature changes and train loads. Since the open bridge deck of a steel bridge will produce a large deformation displacement relative to the rails when the temperature changes, the fasteners are required to have a small longitudinal resistance to the rails to prevent the open bridge deck from moving with the rails when a large deformation displacement occurs. At the same time, in order to improve the stability of the track structure, guard rails are generally installed on the bridge track, which requires that the size of the open bridge deck track fasteners in the direction perpendicular to the rails be as small as possible to ensure the normal installation of the guard rails.
[0003] However, the existing fasteners are complicated to install, difficult to maintain, and unstable, which increases the wheel-rail impact at the rail joint and increases the track vibration and noise. This makes the fasteners easy to loosen, making the track dangerous and reducing the service life of the fasteners. Utility Model Content

[0027] An embodiment of the present application provides a fastener structure for an exposed deck track of a steel beam bridge.

[0028] In the technical solution of the embodiment of the present application, the connecting member 31 is used to facilitate the elastic fastener 3 to limit the installation cross rail 2, and then the limiting block 32 is inserted into the interior of the limiting sleeve 33, and then the mounting plate 34 is limited and installed through the fixing bolt 35 to prevent the fastener from loosening.
[0029] According to other embodiments of the present application, Figure 3 As shown, the buffer component 4 includes a support plate 41 fixedly mounted on the bottom of the mounting rail 2, a gasket 42 fixedly mounted on the upper surface of the base 1, a buffer component 43 fixedly mounted inside the gasket 42, a positioning frame 44 fixedly mounted on the upper surface of the buffer component 43, an inner surface of the positioning frame 44 fixedly connected to a light rod 45, an outer surface of the light rod 45 is sleeved with a buffer spring 46, and a movable part 47 movably mounted on the outer surface of the light rod 45, and the top surface of the movable part 47 is fixedly connected to the bottom of the support plate 41.
[0030] In the technical solution of this embodiment, the support plate 41 is used to withstand the pressure of the installation cross rail 2, which is vibrated and drives the movable part 47 to be pressed down, so that it can slide on the surface of the light rod 45, thereby compressing the buffer spring 46. The buffer spring 46 uses its own elasticity to buffer, and then through the cooperation of the buffer component 43 and the gasket 42, the support effect is improved, thereby improving its stability effect.
