Problems solved by technology

The side forms in this device are still in the traditional way of dismantling and assembling. It takes a long time for the side forms to slide in place as a whole, which is time-consuming and labor-intensive.

Abstract

The invention discloses a vertical-horizontal overall-sliding type side mold of a fulcrum-few support, and relates to the technical field of continuous beam bridge box girder construction. The vertical-horizontal overall-sliding type side mold of the fulcrum-few support saves labor and time, is safe and efficient, comprises a flange mold plate (1), a web mold plate (2), a supporting truss (3) and traveling idler wheels (8), and further comprises a builder jack walkway (5), a flange stop plate (4), a cross support (6), hook bolts (7), supporting lead screws (9), a bearing beam (11), a split threaded rod, a vertical traction system and a horizontal traction system. According to the vertical-horizontal overall-sliding type side mold of the fulcrum-few support, side plates of a box girder can be disassembled, transferred, assembled, adjusted in an elevation mode and the like at a time, the construction difficulty can be effectively reduced, the construction speed can be accelerated, the number of construction devices can be decreased, the construction safety can be guaranteed, and the construction cost can be saved.

Description

technical field [0001] The invention relates to the technical field of continuous girder bridge box girder construction, in particular to a vertically and horizontally integrated sliding side form of a support with few fulcrums. Background technique [0002] At present, the construction technology of cast-in-place box girder with few fulcrum supports is a common method in the construction of continuous girder bridge box girder. However, in the process of continuous box girder span-by-span or unit-by-unit cast-in-situ using less-fulcrum brackets, the side forms need to be dismantled in pieces, and then the span or the unit brackets should be hoisted in pieces by a truck crane, and then transferred to the next span Or the next joint, and finally use the car crane to lift it to the next span or the next joint bracket to reassemble. It is difficult to remove the side formwork of the box girder from under the flange plate of the box girder. Repeated dismantling and assembly are ...
