Abstract
The invention discloses a high and large section bridge deck slab U and V rib joining section assembling method. A tool comprises a bracket where a U and V rib jointing section is placed, opening adjusting bolts, a lead screw jacking system, a vertical rod, a leveling base and other elements. During working, U and V ribs are placed on the bracket, a jacking system nut is rotated to enable the bracket to slowly ascend to the jointing assembly position, then the opening adjusting nuts are utilized for accurately adjusting the jointing section position, spot welding and fixing are carried out after accurate positioning, and the next working procedure is carried out; the leveling base and the vertical rod are connected in an angle-adjustable mode, so that assembly of U and V rib jointing sections at different angle inclined bottom plate positions inside a box body is achieved. The tool is simple in structure, the operation method is simple and fast, the jointing section assembling precision is effectively controlled, and the whole bridge deck slab U and V rib overall straightness is improved, so that the bridge deck slab anti-fatigue performance is improved, and the working efficiency is greatly improved.
