Overlap beams downstriker movable mould frame bridging machine

Abstract

The invention relates to a bridging device, in particular to a laminated beam descending type movable mold base bridge fabrication machine which belongs to the engineering plant. The bridge fabrication machine essentially consists of a main beam, a guiding beam, a comb shape crossbeam, a pier side bracket, a trolley, a counter weight dolly, a hydraulic system template system, etc. The guiding beam is arranged above the trolley. A hydraulic oil cylinder is arranged between the trolley and the guiding beam. The main beam is arranged in the guiding beam. A combination surface of the guiding beamand the main beam is provided with air cushions which are arranged uniformly. The movable mold base bridge fabrication machine changes the upper structure of the prior bridge fabrication machine and ensures that guiding beam and a bearing main beam form movable laminated beams, and the comb shape crossbeam can move independently when opening a mold, thereby increasing the function of the bridge fabrication machine, improving the safety, the reliability and the working efficiency of the equipment and reducing the weight and the cost of the equipment.

Description

technical field [0001] The invention relates to bridge-building equipment, in particular to a pile-beam descending mobile formwork bridge-building machine, which belongs to the category of engineering machinery. Background technique [0002] In bridge construction, the use of mobile formwork to build bridge mechanism beams has been widely used in construction. The mobile formwork bridge building machine can cast concrete at the bridge site, avoiding the one-time investment of large-scale girder transport equipment and prefabricated beam yards, and is especially suitable for complex environments such as soft foundations, deep valleys, and water. It is like a "bridge prefabrication factory" "Moving along the bridge, constructing hole by hole. The mobile formwork bridge building machine is mainly composed of main beams, guide beams, comb-shaped beams, brackets beside piers, trolleys, hydraulic systems, suspensions, formwork systems and platform walkways. [0003] The main gir...

AI Technical Summary

Problems solved by technology

It has higher requirements on the force of the movable door on the main beam, and it is more difficult to connect the comb-shaped beam and movable door during construction, and the construction auxiliary time is longer

Usually, the traditional downward mobile formwork is under the condition of low pier and ultra-low pier, because the main girder structure is too high, the equipment cannot be constructed, and it is necessary to invest in a new formwork support to complete the construction task, which virtually increases the investment in equipment.
