Straddle type monorail transportation rigid framework system

Abstract

The invention discloses a straddle type monorail transportation rigid framework system, and relates to track beams and piers in a straddle type monorail transportation system. In order to increase smooth of lines, reduce the number of monorail transportation track beam expansion joints, eliminate cast steel tension supports, reduce abrasion to rubber wheels and construction cost, and prolong service life of vehicles, the straddle type monorail transportation rigid framework system is designed. The straddle type monorail transportation rigid framework system is composed in a multi-connected rigid frame bridge mode, a rigid frame bridge is formed by connecting concrete track beams which are prefabricated by a workshop on pier bent cap top surfaces through wet joints in a simple support into continuous method, the track beams are prefabricated by the workshop, adjacent two-connected rigid frame bridges are connected through seamless expansion joints or joint plates or plate type rubber expansion joints, and seamlessness of the straddle type monorail transportation lines is achieved.

Description

technical field [0001] The invention relates to a new type of straddle type monorail traffic rigid frame system, which is applied in the civil engineering of straddle type monorail traffic system, specifically a new stress system and track structure of straddle type monorail traffic, replacing the original The simply supported system increases the span of the structure, makes the structure more reasonable and more economical. Background technique [0002] Most of the track beams in the existing straddle monorail transit system are in the form of simply supported beams. Considering the expansion and contraction deformation of the track beams or turnouts when the temperature changes or the foundation settlement, expansion joints are set at both ends of the track beams or turnouts . At present, simply supported PC track beams with an equal height of 1.5m are used, and the maximum span is 24m. Therefore, there are a lot of expansion joints on the line. When the train passes thr...

Problems solved by technology

At present, simply supported PC track beams with an equal height of 1.5m are used, and the maximum span is 24m. Therefore, there are a lot of expansion joints on the line. When the train passes through these expansion joints, it will generate large shock and vibration, which will affect the life of the vehicle and passengers. comfort, increasing the wear and operation and maintenance costs of train rubber tires
