Abstract

The invention provides a curved U-shaped rib assembling device. The curved U-shaped rib assembling device comprises a temporary fixing piece, a telescopic piece and a U-shaped clamping die, wherein afixing seat of the telescopic piece is mounted on a side wall, perpendicular to a horizontal plane, of the temporary fixing piece; and the U-shaped clamping die is detachably connected with a movableend of the telescopic piece, and distance adjustment can be performed on a middle portions of the U-shaped clamping die so that U-shaped ribs of different sizes can be clamped. An assembly line type requirement of a curve U-shaped stiffening rib can be met; an assembling and positioning tool is convenient and simple to disassemble and high in batch manufacturing efficiency, and a problem that traditional assembling and positioning work efficiency is poor is solved; during curve assembly, a boundary dimension of the U-shaped stiffening rib can be guaranteed, and the U-shaped stiffening rib canbe conveniently assembled with a subsequent process; and the device can be suitable for U-shaped stiffening ribs with various sizes.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a curved U-shaped rib assembling device and method. Background technique [0002] In urban viaducts, overpasses, ramps and other curved road bridges, the proportion of steel bridges is increasing day by day. U-shaped stiffening ribs are widely used in the stiffening of the top and bottom plates of steel box girders because of their good anti-torsion performance and strong stability. The manufacturing line type of the curved steel bridge is a spatial curve, the plane adopts transitional curves, circular curves, compound curves, etc., and the facade line type adopts one-way longitudinal slopes, vertical curves, etc. As a result, during the manufacturing and construction process, it is necessary to control the "U" section size of the U-shaped stiffener and at the same time meet the requirements of the steel bridge manufacturing line. [0003] The existing curved U-shaped stiffene...
