Description

TECHNICAL FIELD

[0001] The utility model relates to bridge construction technical field especially relates to a bridge builder outer mould opening and closing device. BACKGROUND

[0002] The bridge builder is a load-bearing frame capable of sliding or rolling along the top of the beam, which is anchored and suspended on the constructed beam section. The formwork, reinforcement, prestressed pipe of the next beam section can be installed on the bridge builder, and the concrete pouring, prestressed tensioning, grouting and other operations can be carried out. After completing the cycle of a section, the bridge builder can be moved forward and fixed to carry out the cantilever pouring of the next section, and the cycle continues until the cantilever pouring is completed. The bridge builder has the advantages of light weight, simple structure, firmness and stability, easy to move and disassemble, strong reusability, small deformation under stress, and sufficient space under the bridge builder to provide a large construction operation area for the reinforcement and formwork construction operation.

[0003] In the current bridge construction operation process, the lifting boom device is widely used to realize the opening and closing operation of the formwork. However, in actual application, due to the poor rigidity performance of the boom material, the formwork will produce a relatively violent shaking phenomenon during the opening of the formwork, which not only easily causes accidental collision to the beam structure that has been poured, thereby damaging the surface quality and structural integrity, but also invisibly buries the safety hazard and threatens the life safety of the construction personnel. In addition, during the longitudinal or transverse movement of the bridge builder, if the formwork system cannot achieve the expected stable connection state, it will also cause significant shaking of the formwork, and may also cause additional impact load to the walking mechanism. Long-term effect will accelerate equipment wear and tear, shorten the service life, and may cause more serious safety accidents.
