Technical Field

The specification relates to the field of bridge engineering, in particular to a continuous rigid frame track beam.

Background

The track beam is not only a track for the monorail train to walk, but also a bearing structure of the track beam. The current general track beam structure system mainly comprises a simply supported system and a continuous rigid frame system. In order to reduce the dead weight, the conventional simply supported system track beam at home and abroad adopts a hollow section form. And the continuous rigid frame system has no application engineering example at present at home, and the application engineering at home and abroad adopts the hollow section track beam, so that the high-degree hollow section track beam has high requirements on the construction quality control of the track beam.

Based on the stress characteristics of a continuous rigid frame system, the solid-section continuous rigid frame track beam is provided, the conventional foreign continuous rigid frame track beam is a hollow section, the width of the track beam is small, reinforcing steel bars are densely distributed, the difficulty of reinforcing steel bar binding, concrete pouring and vibrating is large, the construction speed is low, and the construction quality is not easy to control. How to improve the construction speed of the continuous rigid frame track beam and ensure the construction quality is an urgent problem to be solved.

Disclosure of Invention

In order to solve the technical problems, the specification provides a continuous rigid frame track beam, in particular to a light straddle type monorail track beam structure.

The section of the continuous rigid frame track beam is a solid section,

the solid section is in a rectangular shape,

the height of the continuous rigid frame rail beam between adjacent pier body capping beams is variable,

the height of the first track beam part of the continuous rigid frame track beam, which is positioned at the pier body bent cap supporting point, is greater than that of the second track beam part of the continuous rigid frame track beam, which is positioned at the midspan part.

Compared with other structures such as a hollow-section simply-supported track beam and a hollow-section continuous rigid frame track beam, the hollow-section simple-supported track beam has the advantages of light and attractive appearance, high construction speed, convenience in construction quality control, high economical efficiency and wide application space.

This structure adopts continuous rigid frame system, can avoid the letter system to set up expensive bridge beam supports and avoid the trouble on the later stage support maintenance, and kept the continuous beam expansion joint few, the smooth-going advantage of driving, can transfer the fulcrum hogging moment to with the girder part of the positive moment of flexure in striding effectively again simultaneously, share roof beam portion atress, reduce the fulcrum roof beam height, be convenient for design into the roof beam shorter than the continuous beam, satisfy the low headroom requirement, penetrating in the sense of coincidence, fine aesthetic feeling. And with reference to fig. 3, the section of the track beam adopts a solid rectangular section, so that the influence of the space occupied by the hollow section internal mold and the facing steel bar is eliminated, and the construction quality control is facilitated. And after the structural calculation comparison, the stress is better than that of a hollow section, and the construction cost can be properly reduced.
