Description
Technical Field
The invention relates to bridge construction equipment, in particular to a bridge fabrication machine for cantilever pouring construction.
Background
The cantilever casting construction is a construction method of symmetrically and balancedly casting a concrete beam body section by section to the midspan by adopting special equipment at two sides along the bridge direction with a bridge pier as the center, and applying prestress section by section. The hanging basket is a special device which is used for bearing the self weight and the construction load of a beam body and can move forwards section by section when the concrete beam body is poured by a cantilever method, and mainly comprises a main truss, a main truss supporting and rolling device, an inner mold and an outer mold for forming the concrete beam body. Generally speaking, in the cast-in-place cantilever construction process, the construction period of each standard section is about 7 working days, wherein the on-site binding and assembling time of the reinforcement cage is about 2 to 3 working days, which is one third of the construction period of each standard section, and thus the construction period of the continuous beam is not shortened.
Chinese patent document CN 102174796B discloses a main truss underneath type suspended casting construction hanging basket, which saves the upper construction space by arranging the main truss below the beam surface, and solves the problem that the reinforcement cage cannot be integrally hoisted due to insufficient upper construction space. According to the technical scheme, the inner die is assembled after the integral hoisting of the steel reinforcement cage is completed, so that the adverse effect of the inner die on the hoisting of the steel reinforcement cage in place is avoided, the time required by assembling the inner die is long, and the construction period is not further shortened. The conventional integral internal mold can save the time required by assembling the template, but the integral internal mold and the main truss move forwards synchronously, and when the whole steel reinforcement cage is hoisted in place, the internal mold is already in place, so that certain obstruction can be generated, and the operation difficulty of the whole hoisting of the steel reinforcement cage is increased.
In addition, traditional single-truss main truss rear supporting point idler wheels are single-row wheels and are of a one-way hinged structure, the problems that idler wheel pressure is large, lateral pressure is uneven and the like exist, when the thickness of a concrete beam wing plate is small, concrete crushing is easy to cause, and meanwhile when the hanging basket is placed forwards, the main truss cannot be guaranteed to be in a horizontal state, and certain safety risk exists.
A traditional hanging basket is generally provided with a bearing beam bearing template load, the bearing beam is directly arranged on a main truss, meanwhile, working load is transmitted to the main truss, and then the load is transmitted to a constructed beam through the main truss. In the construction process, the position of the main truss deviates from the designed position to a certain extent, and the hanging basket needs to be demolded before running, so that the position of an outer die needs to be adjusted in the construction process, and the adjustment of the position of the outer die needs to be realized by adjusting the position of the main truss. The adjustment operation of the position of the main truss is complex, and needs a plurality of persons to operate simultaneously, which brings great inconvenience to the construction and has low adjustment efficiency. And when the outer die is used for erecting the die, the outer die is provided with a hole at the beam bottom position so that the opposite pull rod can penetrate through the hole, and the opposite positions of the outer dies at the two sides are fixed by the opposite pull rod. The method is convenient for the conventional equal-height section beam, but for the variable-height section beam, holes need to be continuously formed in corresponding positions on the outer die along with the continuous change of the beam height, and the construction efficiency is influenced.
