Description
Technical Field
The invention relates to bridge construction equipment, in particular to a bridge fabrication machine for cantilever pouring construction.
Background
Cantilever pouring construction refers to a construction method for pouring concrete beam bodies in a symmetrical and balanced way section by section to span way on two sides of a forward bridge taking a bridge pier as a center and applying prestress section by section. The cradle is special equipment which is used for bearing the self weight of the beam body and the construction load and can move forward section by section when the concrete beam body is poured by cantilever method, and mainly comprises a main truss, a main truss supporting rolling device, an inner die and an outer die for forming the concrete beam body. Generally, in the cantilever casting 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 accounts for one third of the construction period of each standard section, and the construction period of the continuous beam is not beneficial to shortening.
Chinese patent document CN 102174796B discloses a hanging basket for hanging and casting under a main truss, which saves the upper construction space and solves the problem that the reinforcement cage cannot be integrally hoisted due to insufficient upper construction space by arranging the main truss under a beam surface. According to the technical scheme, after the whole hoisting of the reinforcement cage is completed, the inner mold is assembled again, and adverse effects on the hoisting of the reinforcement cage in place by the inner mold are avoided, but the time required for assembling the inner mold is long, so that the construction period is not facilitated to be further shortened. The conventional integral internal mold can save the time required for assembling the templates, but moves forward synchronously with the main truss, and the internal mold is already in place when the steel reinforcement cage is integrally lifted in place, so that a certain obstruction can be generated, and the operation difficulty of the integral lifting of the steel reinforcement cage is increased.
In addition, fulcrum gyro wheel is single row's wheel behind traditional single pin main truss, and is one-way hinge structure, exists gyro wheel pressure big, side direction pressure inequality problem, when concrete beam pterygoid lamina thickness is less, causes concrete to crush easily, when hanging the basket and transferring the antedisplacement simultaneously, the main truss can't guarantee to be in the horizontality, exists certain security risk.
The traditional hanging basket is generally provided with a bearing beam for bearing the template load, the bearing beam is directly arranged on the main truss, meanwhile, the working load is transferred to the main truss, and the load is transferred to the constructed beam through the main truss. Because in the work progress, main truss position can produce certain deviation with the design position to need to carry out the drawing of patterns before the cradle walks, need adjust outer die position when leading to the construction, and outer die position adjustment need be realized through adjusting main truss position. The main truss position adjustment operation is complex, multiple people are required to operate simultaneously, and therefore a plurality of inconveniences are brought to construction, and the adjustment efficiency is low. And when the outer die is erected, holes are formed in the outer die at the beam bottom position so that the opposite pull rods can pass through the outer die, and the opposite positions of the outer dies at the two sides are fixed by the opposite pull rods. For a conventional equal-height section beam, the method is convenient, but for a variable-height section beam, as the height of the beam is continuously changed, holes are required to be continuously formed in corresponding positions on the outer die, and the construction efficiency is affected.
