Description

Continuous beam internal mold Technical Field The utility model relates to the technical field of basket hanging construction, in particular to a continuous beam inner die. Background The continuous beam bridge is used as an important component of modern traffic infrastructure, and is widely applied to expressway, railway and urban interchange engineering due to the advantages of strong structural integrity, large crossing capacity and the like. In continuous beam construction, the basket hanging cantilever pouring technology becomes a core technology of large-span bridge construction, and the key point is that the high-precision control of the geometric dimension of the section of the box girder is realized through the cooperative operation of an inner template system and an outer template system. The top die, the side die and the corner die of the conventional continuous beam inner die are assembled by adopting steel dies with different specifications, so that the conventional hanging basket inner die is basically generalized, but a bridge segment at the position with a tooth block cannot be poured by adopting the conventional inner die, when the segment with the upper tooth block is poured, the steel die corresponding to the position of the upper tooth block needs to be detached from a back frame, the wood die is assembled by on-site repair processing, the temporary support is added, pouring is performed after the temporary support is added, when the segment with the lower tooth block needs to be poured, the steel die corresponding to the position of the lower tooth block needs to be detached, and the wood die is assembled by on-site repair processing. According to the construction method, the tooth block template is required to be redesigned, so that the labor cost is increased, the wood pattern forming effect is poor, the stability of the structure is affected, when the conventional hanging basket top mold and the conventional hanging basket back frame are used for construction, temporary supports are required to be redesigned according to different top tooth blocks, the complexity of field design is increased, the manufacturing cost is increased, and the construction efficiency of the inner mold is greatly prolonged.
