Polygonal-section bridge pier stud reinforcement cage integral hoisting and binding jig and using method

Abstract

The invention relates to a polygonal-section bridge pier stud reinforcement cage integral hoisting and binding jig and a use method. The jig comprises fixed limiting bottom plates, detachable limitingside plates and a detachable limiting top plate; and the fixed limiting bottom plates comprise a transverse limiting bottom plate and a longitudinal limiting bottom plate, round steel short heads arearranged on the transverse limiting bottom plate at designed reinforcement cage main reinforcement intervals, round steel short heads are arranged on the longitudinal limiting bottom plate at designed reinforcement cage hooping intervals, one ends of the detachable limiting side plates are detachably connected to the two sides of the fixed limiting bottom plate, and thin steel pipes are arrangedon the plate faces of the detachable limiting side plates at designed reinforcement cage vertical main reinforcement intervals. By using the binding jig, a reinforcement cage can be quickly bound, themanufacturing efficiency of the reinforcement cage is improved, the interval between reinforcements can be effectively controlled through the binding jig, a reinforcement cage hoisting limiter limitsdeformation of the reinforcements during integral hoisting of the reinforcement cage, and the positioning precision of the reinforcement cage is guaranteed.

Description

technical field [0001] The invention relates to the field of steel cage binding tires, in particular to the integral hoisting and binding tires of steel bar cages with polygonal cross-section bridge pier columns and a use method. Background technique [0002] At present, domestic bridge pier column reinforcement is mainly divided into two construction techniques: pre-embedded joint reinforcement on the cap and then on-site binding and overall hoisting of the reinforcement cage. In the case of complex cross-sections of pier columns, the construction technology of pre-embedded joint steel bars and then on-site binding is usually used; in the case of relatively simple cross-sections of pier columns, such as circular ones, the construction technology of integrally hoisting steel cages is usually used. [0003] Some engineering standard bridge pier types include hexagonal pier and vase pier, which are polygonal cross-sections. If the on-site binding construction technology is ad...
