Abstract

The invention discloses an ascending type movable formwork box beam concrete pouring construction method. A symmetrical balance pouring principle is adopted to pour concrete to elastic beam sections at the same time in a transverse manner and a longitudinal bridge direction manner; and the symmetrical balance pouring principle is adopted to pour concrete to non-elastic beam sections at the same time in a transverse manner and a longitudinal bridge direction manner. By the adoption of the ascending type movable formwork box beam concrete pouring construction method, a box beam structure is kept in an elastic system state, finally a unified whole is formed, the quality problems that box beams near a middle cross beam are not coordinative, and deformation and cracks are generated are effectively solved, deformation structure cracks and cold seams are effectively prevented from being generated in the pouring process, and the box beam construction quality is effectively guaranteed. The box beams are poured according to the symmetrical balance principle, it is guaranteed that a movable formwork is loaded in a balanced manner, and safety and reliability are achieved. Construction resources are configured reasonably, the pouring process is not intercepted, the construction speed is high, the mechanical use rate is high, and the construction efficiency is high.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an upward moving formwork box girder concrete pouring construction method. Background technique [0002] The mobile formwork is a self-propelled special equipment for bridge construction with its own formwork, supported by caps or pier columns. The upward mobile formwork system is mainly composed of main beam, nose bridge, upper beam, hanging beam, front outrigger, middle outrigger, small and medium trolley, rear sliding beam, etc., and is equipped with a corresponding hydraulic and electrical system. The upward moving formwork has the advantages of simple equipment and technology, safe construction, high degree of mechanization, short construction period and stable construction quality. [0003] In order to ensure the construction quality during the concrete pouring process of the cast-in-situ box girder with the upward mobile formwork, and at the same time ensure the struc...
