Description

Integral sliding universal bracket for pier top area section beam construction Technical Field The invention relates to the technical field of bridge construction, in particular to an integral sliding universal bracket for pier top area section beam construction. Background Along with the gradual development of bridge construction, future technologies are expected, and future piers, bearing platforms and the like are changed into large and heavy appearances, so that the 'small-body plates and large energy' are fully displayed, and a larger span is realized. The structural form of 'small body plates and large energy' is more concentrated in weight, so that difficulty is brought to bracket construction, particularly, the continuous beam 0# block section (also called pier top area section beam) needs to be constructed to support a casting template during casting construction, and the continuous beam 0# block section with a very small supporting surface is not good for supporting casting. In the related art, in order to solve the above problems, a relatively wide technical scheme is adopted in the prior art, and belongs to an embedded part bracket scheme and a tubular pile floor stand scheme. However, when the transverse width of the pier body is narrower, the embedded part bracket cannot align the web plate of the girder body to provide effective support for the cast-in-situ construction of the segmental girder, when the bearing platform is a round bearing platform or the plane size is smaller, the tubular pile floor support cannot provide enough supporting surface, part of the tubular pile floor support is supported on the bearing platform, part of the tubular pile floor support is supported on the ground, uneven settlement is caused by different bottom supporting strength of the floor support, and the problems that the high-altitude welding workload is large, the construction safety risk is high, the support erection and dismantling work efficiency is low, the structural pertinence is strong, the circular use is not facilitated and the like still exist in the two technical schemes.
