Novel straddle type monorail double-line combined track beam structure

Abstract

The invention discloses a novel straddle type monorail double-line combined track beam structure. The structure comprises two opposite track beams, wherein each track beam comprises steel boxes and prefabricated OPC plates; the steel box comprises two opposite webs; the top of each web is connected with a top plate to form a T-shaped plate structure; a plurality of shear force toggle pins are arranged on each top plate; one prefabricated OPC plate is arranged between every two adjacent shear force toggle pins; bulges are arranged at the lower parts of two ends of each prefabricated OPC plate;the area between the ends of every two adjacent OPC plates is poured; the two track beams are connected through a plurality of triangular parallel connectors; one edge of each triangular parallel connector is transversely bolted between the two track beams and the other two edges of the triangular parallel connector are connected with the cross edge of the former adjacent triangular parallel connector; an upper horizontal separation plate and a lower horizontal separation plate are arranged in each steel box along the longitudinal direction of the track beams; all the horizontal separation plates are connected between the two webs; the upper horizontal separation plates are located at action positions of train steady wheels; and the lower horizontal separation plates are located at top plate height positions of the triangular parallel connectors.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a novel straddle-type single-track double-track combined track beam structure. Background technique [0002] Straddle-type monorail traffic is a new urban transportation mode. Compared with ground public transportation, it has the advantages of large transportation capacity, fast speed, and strong climbing ability. At the same time, it can effectively alleviate urban traffic congestion and save people. travel time. In the monorail traffic system, the track beam has the dual functions of load bearing and vehicle guidance, which is very important to the monorail traffic system. However, the track beams of the existing monorail traffic basically use concrete structure track beams. The heavy weight and poor tensile strength make this kind of beam prone to cracks, which has great limitations in use. [0003] In conventional steel-concrete composite track beams, several diaphragms ...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the conventional steel-concrete composite structure track girder existing in the prior art, several diaphragms are arranged at intervals in the steel box of the rail girder, and the web between the two diaphragms is at the center of the train stabilizing wheel. It is easy to deform under continuous action, which makes the gap between it and the train's stable wheel continuously increase, which affects the driving safety. The double-line composite track beam structure is generally welded to the steel box of the composite track beam by diagonal diagonal braces. This connection causes There are many welds in the structure, and the damage is relatively large. Under the action of tensile load, the steel box is easy to crack, which makes the track beam damaged and causes the above-mentioned shortcomings of engineering accidents. A new type of straddle-type single-track double-line composite track beam structure is provided.
