Embodiment Construction

[0023] Please refer to Fig. 1~Fig. 9, all the same components in the figure are represented by the same symbols. As can be seen from the figures, the track structure of the present invention mainly includes: track beam 3, the sleeper 2 supported and fixed on the track beam 3 by a connecting structure, and the guide rails (F steel plates) supported and fixed on both sides of the upper surface of the sleeper 2 )1.

[0024] As shown in Figure 3, the connection structure mainly includes a spacer 4 with a T-shaped cross-section and fasteners such as bolts 6. Height-adjusting washers 8, leveling bolts 10 and elastic Backing plate 9. In addition, for the convenience of connection, an embedded steel plate 5 can be arranged on the spacer 4 .

[0025] The cushion block 4 is arranged between the guide rail 1 and the track beam 3 . Pad 4 is made of concrete material, can be prefabricated in factory, also can support formwork to make on the spot. On the one hand, the block 4 plays the ...

Abstract

The invention provides a track structure of magnetic floating traffic, comprising a track beam, railroad ties supported and fixed on the track beam via a connecting structure and a track supported and fixed at two sides of the upper surface of the railroad ties, wherein the connecting structure comprises a fixer and a concrete block, the railroad tie is made from hollow square steel tube. The invention also provides a relative production, comprising that preparing the track beam with preformed holes, preparing a track arranger formed by a track and railroad ties, while the railroad tie is made from hollow square steel tube, connecting and fixing the arranger on the track beam via the connecting structure, while the connecting structure comprises a fixer and a concrete block. The invention uses square tubular steel railroad ties to improve the rigidity, distortion resistance, and longitudinal deformation resistance, to improve the safety and reliability of the track, and uses a novel flexible buckle plate to make installment easy and improve vibration proof ability.

Description

technical field [0001] The present invention generally relates to a track structure, in particular to a track structure for low-speed maglev traffic and a manufacturing method thereof. Background technique [0002] The track structure of the low-speed maglev system mainly includes guide rails (often referred to as F steel plates because of their cross-section resembling a lying "F"), sleepers, track beams and connecting parts between them. Among these components, the F steel plate is used for the suspension and guidance of the train, the sleeper is used to support and fix the F steel plate, the track beam is used to support and fix the sleeper, and the connecting parts are connected and fixed between the structural parts. [0003] Among them, the sleepers in the current track structure basically adopt the type of welded I-shaped steel. Welded I-shaped steel sleepers are composed of upper and lower flanges and webs. The F steel plate is generally connected to the upper flan...
