Problems solved by technology

At present, there is no high-speed maglev transportation project in the world, and there is also a lack of track technology that matches the high-speed system. In order to further tap its speed advantage and develop high-speed maglev transportation, my country is currently exploring high-speed maglev transportation.

Embodiment Construction

[0024] In order to further illustrate the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but they should not be construed as limiting the protection scope of the present invention.

[0025] The slab-on-beam track beam provides a variety of line types. The single-line track on the beam and the multi-line track on the beam can be used. If the load-bearing beam is a multi-line slab track beam structure, the distance between the track slabs must meet the limit requirements. Each line type is composed of upper concrete track slab 1, edge pier column 2, middle pier column 3, lower load-bearing beam 4 and slab pier connection key 5. The upper concrete track slab 1 takes 3.096 meters or other modulus as a system unit, and is manufactured and machined in the factory. The prestressed concrete box girder used by the lower load-bearing beam 4 can adopt a simply supported structure or a continuous str...

Abstract

The invention relates to a wide flange beam slab plate type rail beam, and belongs to the field of magnetic levitation transportation. The rail beam comprises concrete track plates, side pier columns,middle pier columns, a lower bearing beam and plate pier connecting keys, wherein the concrete track plates are connected with the lower bearing beam through the side pier columns, the middle pier columns and the plate pier connecting keys, the upper part of a box body of the lower bearing beam of the rail beam is outwards unfolded to form the upper surface horizontal flange, the horizontal flange facilitates evacuation of personnel; and the part between the concrete track plates and the lower bearing beam is connected through the plate pier connecting keys, the side pier columns and the middle pier columns which are capable of adjusting the displacement. The wide flange beam slab plate type rail beam has the advantages that a plurality of linetypes are provided, the structure is reasonable, the force transmission is clear, the design is novel, materials are saved, the installing precision is high, and vibration deformation is small.

Description

technical field [0001] The invention belongs to the field of maglev transportation, in particular to a slab-top track beam on a wide flange beam. Background technique [0002] Maglev transportation is currently the fastest rail transportation mode in the world, with the advantages of high speed, energy saving, and low vibration and noise. On the basis of introducing and absorbing German technology, my country has built a number of maglev test lines through independent innovation. At present, there is no high-speed maglev transportation project in the world, and there is also a lack of track technology that matches the high-speed system. In order to further tap its speed advantage and develop high-speed maglev transportation, my country is currently exploring high-speed maglev transportation. Compared with the existing technology, its speed is greatly increased, and it puts forward new and more difficult requirements for vehicles and tracks. The track structure is one of th...
