Adjusting system for folding midspan beam sections

The utility model provides an adjusting system for mid-span beam section closure. The adjusting system comprises a first beam body and a second beam body which are located on the two sides of a closure section mid-span wet joint respectively. The first vertical deformed steel bar is anchored and assembled on a higher first beam body, and the first vertical deformed steel bar extends into the first beam body; and the second vertical deformed steel bar extends into the second beam body in the vertical direction, and the second vertical deformed steel bar and the second beam body generate tensioning prestress, so that the higher first beam body is stressed downwards, and the lower second beam body ascends until the first beam body and the second beam body are at the same height. A stiff framework adjusting system is adopted and can be recycled in other midspan closure sections, and the links such as static pressure material transferring and hoisting installation are omitted. 本实用新型提供了用于跨中梁段合拢的调节系统，包括分别位于合拢段跨中湿接缝两
