Beam part construction movable canopy and construction method thereof

Abstract

The invention provides a beam part construction movable canopy and a construction method thereof. The beam part construction movable canopy comprises a rail supporting part, moving guide rails, canopyuprights and canopy trusses; the rail supporting part comprises at least eight joist steels arranged along a vertical direction; the joist steels are distributed and fixed at both opposite sides of acast-in-situ beam along a length direction of the cast-in-situ beam; at least four joist steels are arranged at each side; the tops of the joist steels are all positioned on the same horizontal plane, and the tops of the joist steels are higher than the top surface of a template by 30 to 50cm; the moving guide rails are respectively arranged at both opposite sides of the cast-in-situ beam along the length direction of the cast-in-situ beam, and the moving guide rails are both welded and fixed at the upper ends of the joist steels forming the rail supporting part. Therefore, a problem of serious influence on the construction progress, which is caused by a case that a cast-in-situ beam part structure of a bridge is influenced a lot by rainwater in the construction, is solved. The inventionbelongs to the field of bridge construction.

Description

technical field [0001] The invention relates to a protection measure and a construction method for a movable canopy on a beam part, belonging to the field of bridge construction. Background technique [0002] At present, the cast-in-place girder structure of bridges is greatly affected by rainwater during construction, and the construction progress is often affected by rain, especially in the rainy season. There is no good solution at this stage. Contents of the invention [0003] The object of the present invention is to provide a mobile canopy for beam construction and its construction method to solve the problem that the cast-in-place beam structure of a bridge is greatly affected by rainwater during construction and seriously affects the construction progress. [0004] In order to solve the above problems, it is planned to adopt such a construction method of beam construction mobile canopy, the specific steps are as follows: [0005] Step 1: Install the track, take th...
