Double-line track beam supporting system suitable for suspension type monorail and construction method

Abstract

The invention provides a double-line track beam supporting system suitable for a suspension type monorail, which comprises two lines of track beams arranged side by side, a pier and a cross beam are arranged between the two lines of track beams and positioned at the end parts of the track beams, a pier top cover beam is arranged at the top of the pier, and the bottom of the cross beam is supportedon the pier top cover beam of the pier through a support. The two ends of the cross beam are connected with the side faces of the two lines of track beams into a whole. In addition, the invention further provides a construction method of the double-line track beam supporting system. On the premise of meeting the vehicle traveling requirements, the double-line track beams are connected into a whole through the cross beam, a conventional single-line beam is converted into the double-line beam, and the pier top cover beam is arranged between the two track beams, so that the pier height is effectively reduced, and the stress and stability of the track beams and the pier structure are improved; meanwhile, track beam and pier materials are more fully utilized, the steel consumption can be greatly reduced, construction is simple, later maintenance and repair are convenient, and economic and technical benefits are obvious.

Description

technical field [0001] The invention belongs to the technical field of suspended monorails, and in particular relates to a double-line track beam support system suitable for suspended monorails and a construction method. Background technique [0002] At present, the commonly used support systems of suspended monorail mainly include pin type and support type. [0003] The plug-type support system uses T-shaped piers in the double-line bridge section to suspend the track beams on both sides of the bridge pier cover beam through the hanging plate. In actual use, the upper hanging plate of the track beam and the upper hanging plate of the cover beam are connected to their main body by welding. Because they are in a suspended state, the welds are not uniformly stressed, and local stress will be relatively large, leading to prominent fatigue problems. In addition, the bolt-type connection can only be successfully connected if the bolt holes of the hanging plate correspond to each...

AI Technical Summary

Problems solved by technology

[0005] Both the conventional pin-type and support-type support systems place the track girder under the overhang of the T-shaped pier, and the pier and cover girder need to be higher than the track girder, which has poor aesthetics, and the pier height is high, and the deformation of the pier top is often large

In addition, the track beams on both sides are independent structures without any connection, their lateral deformation resistance is weak, the lateral deformation of the curved section is large, and the driving comfort is poor
