Embodiment Construction

[0068] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0069] refer to figure 1 , the present invention provides a construction method for track beams, which is used to fill the technical gap in the field of straddle-type monorail traffic that has not yet matured in simple-supported variable continuous construction in China, and provides valuable construction experience for the field of straddle-type monorail traffic . The simply supported variable connection structure of the track beam completes the rotation axis of the structural system, and its cast-in-place connection section and the track beam are directly used as the running surface of the locomotive, which requires very high accuracy for the erection of the track beam and the conversion of the structural system. Below in conjunction with accompanying drawing, the construction method of track beam of the present invention is described.

Abstract

The invention relates to a construction method of a track beam, comprising the following steps: a pier column is constructed at a position where the track beam is arranged; A temporary supporting device is arranged on the side of the pier column corresponding to the rail beam to be installed; Hoisting the rail beam on a temporary support device between two adjacent pier columns, and supporting therail beam through the temporary support device; And aligning the ends of the rail beams on both sides of the same pier column, and connecting the cast-in-situ connection segments with the relativelyaligned rail beams on both sides of the same pier column, and supporting the cast-in-situ connection segments on the pier column, thereby completing the construction of the simply supported variable connection structure of the rail beam. The invention adopts the temporary supporting device arranged at the side of the pier column to erect the track beam, and utilizes the temporary supporting deviceto support the track beam, and further utilizes the cast-in-situ connection section to complete the butt joint between the track beams, that is, the track beam and the pier column are connected together through the cast-in-situ connection section to form the simple-supported variable continuous structure.

Description

technical field [0001] The invention relates to the field of monorail traffic engineering, in particular to a construction method for a track beam. Background technique [0002] With the development of society, the fast and light characteristics of light rail transit have been more and more reflected, and the construction scale of straddle-type monorail transit as a medium and low traffic volume is also increasing. Both BYD Cloud Rail and Chongqing Light Rail are small-span simple-supported beam structures. The structure of Wuhu Light Rail under construction is a continuous rigid structure. At present, in the field of straddle-type monorail transportation, there is no mature simply-supported variable continuous construction technology and success in this area. construction experience. Therefore, there is an urgent need to provide a construction method for track beams to fill up the technical gap in the field of straddle-type monorail transportation. Contents of the invent...
