F sectional steel connecting structure for medium-low-speed magnetic levitation system

Abstract

The invention discloses an F sectional steel connecting structure for a medium-low-speed magnetic levitation system. The F sectional steel connecting structure comprises a wing plate lower connecting plate, a clamp plate, an outer leg side connecting plate and two sections of F sectional steel, wherein each section of F sectional steel is provided with an inner leg, an outer leg, a web plate and a wing plate, the two ends of the wing plate lower connecting plate are respectively connected with the wing plates arranged at the two sides through first screw bolts and the clamp plate, a groove longitudinally extending along the line is formed in the side wall of each outer leg, the outer leg side connecting plate is provided with a long slot groove at one side near the clamp plate, and is provided with a round hole at one side leaving far away from the clamp plate, and the outer side connecting plate is fixedly arranged in the groove through second screw bolts. The F sectional steel connecting structure for the medium-low-speed magnetic levitation system has the advantages that the structure is simple, the processing cost is low, the installation is convenient, and the maintenance is easy.

Description

technical field [0001] The invention relates to the technical field of medium and low speed maglev rail transit, in particular to an F-shaped steel connection structure of a medium and low speed maglev system. Background technique [0002] The track structure of the medium and low speed maglev system is mainly composed of a block rail row, a fastener system and a rail support platform. The rail row can be assembled on site or in the factory, and connected with the rail bearing platform poured on site through the fastener system. At the same time, in order to adapt to the deformation caused by the temperature change of the lower foundation and the rail row, expansion joints and expansion joints should be set between the rail rows The size should be non-zero at the highest temperature in history to ensure that there is no tension between the rail rows, and not exceed the structural rail gap at the lowest temperature in history to ensure smooth running of the train.

Problems solved by technology

[0004] Although the above connection structures can theoretically meet the connection requirements of the rail row, there are still cases where the connection structure is not suitable for the temperature expansion and contraction of the rail row.
