Abstract

The invention discloses a straddle type monorail prestressing reactive powder concrete track beam. The cross section of the track beam is a hollow I-shaped cross section. The bottom of the track beam is provided with a plurality of prestressing tendons. The prestressing tendons extend in the length direction of the track beam. The prestressing tendons are distributed in a U-shaped manner at the cross section of the track beam. The span of the track beam is 30-40m. According to the reactive powder concrete track beam, the disadvantages that a PC track beam is short in economic span and poor in endurance are overcome, and the problems that for a steel track beam, the amount of steel used is large, vibration noise is high and skid resistance performance is poor are also solved.

Description

technical field [0001] The invention belongs to the field of straddle-type monorail track beams, and in particular relates to a straddle-type monorail prestressed active powder concrete track beam. Background technique [0002] The middle track beam of the straddle monorail plays a dual role of bearing the load of the vehicle and forming the running track of the train. Its performance is directly related to the stability of the track system, and it is called the lifeline of the straddle monorail traffic. At present, the types of track beams mainly include PC track beams and steel track beams, which mainly have the following defects in the actual engineering application process: [0003] (1) The span of PC track beam is controlled by the section size, which becomes the bottleneck restricting the development of track beam. In the early Hitachi straddle-type monorail, the PC track girders had a basic span of 20 meters and 22 meters. Due to the limitation of the span, the amou...
