Steel truss girder supporting system suitable for asymmetric suspended monorail

Abstract

The invention discloses a steel truss girder supporting system suitable for an asymmetric suspended monorail and belongs to the field of suspended monorails. Through arrangement of the steel truss girder supporting system correspondingly composed of an upper chord, a first lower chord and a second lower chord, the asymmetric suspended monorail is effectively supported, wherein the cross section ofthe steel truss girder supporting system is triangular. The steel truss girder supporting system suitable for the asymmetric suspended monorail is simple in structure, easy and convenient to arrange,capable of effectively meeting the requirements for supporting and operation of the asymmetric suspended monorail, reducing use of steel, improving the reliability and stability of the supporting system, shortening the construction period of the supporting system and reducing the construction cost of the supporting system, good in application and popularization value and wide in application prospect.

Description

technical field [0001] The invention belongs to the field of suspended monorails, and in particular relates to a steel truss support system suitable for asymmetric suspended monorails. Background technique [0002] Monorail transit system is a relatively common rail transit system, which together with subway transit system and light rail transit system constitute the three most common types of urban rail transit. In the monorail traffic system, according to the different running modes and track structures, it is mainly divided into suspension monorail traffic and straddle monorail traffic. [0003] Among them, the suspended monorail transportation system is a new type of lightweight, small and medium-sized urban rail transit form, which often has the characteristics of safety, reliability, high efficiency and environmental protection, relatively low engineering cost, short construction period, good sightseeing and good terrain adaptability And other advantages, it is widely...

Problems solved by technology

It can be seen from the content of the prior art that there are few studies on the support system of the suspended monorail traffic, especially the related research on the asymmetric suspended monorail traffic, and in the prior art, the track beam of the asymmetric suspended monorail traffic Most of them use a box girder structure under the cantilever of the bridge pier, and then set a track for asymmetrically suspended monorail vehicles on one side of the box girder structure. As shown in the existing Chinese patent CN 201810999164, although this setting form It can meet the needs of asymmetric suspended monorail traffic to a certain extent. However, the above-mentioned arrangement also has many defects, which are mainly reflected in: the box girder structure often needs to be arranged under the cantilever structure of the pier, and the gap between the box girder structure and the cantilever Correspondingly connected by connection structures, a tensile connection system is formed. The reliability of the tensile connection system is poor, the performance requirements are high, the cost is high, and the structure is complex. Higher requirements, which will not only increase the difficulty of design and construction of the support structure, but also increase the construction cost of the suspended monorail traffic support system, so there are great limitations
