Detachable lower ball seat for high-speed bridge swivel steel support

Abstract

The invention provides a detachable lower ball seat for a high-speed bridge swivel steel support, and relates to the technical field of bridge construction, capable of solving the problems that when an existing lower ball seat for a detachable bridge swivel steel support is disassembled, and a bridge needs to be jacked up firstly and then disassembled, and the operation of jacking up the bridge firstly is extremely difficult, and the bridge is jacked up and then falls down, and great potential safety hazards exist in the bridge, and deviation is likely to occur in the falling position. The detachable lower ball seat includes a lower ball seat, wherein a lower spherical hinge is horizontally mounted at the upper end of the lower ball seat. According to the detachable lower ball seat for a high-speed bridge swivel steel support, the left end edge and the right end edge of the lower ball seat are respectively and fixedly provided with the horizontal side support plates; in conclusion, when construction is finished, the squeezing block can be separated from the self-discharging block, and the lower spherical hinge part falls down, and therefore a gap is reserved between the device anda bridge, and the detachable lower ball seat for a high-speed bridge swivel steel support can be freely withdrawn, and in conclusion, the detachable lower ball seat for a high-speed bridge swivel steel support is safer, more efficient and extremely high in repeated utilization rate when used.

Description

technical field [0001] The invention relates to the technical field of bridge construction, and more specifically relates to a detachable lower ball seat for a high-speed bridge swivel steel bearing. Background technique [0002] At present, in the domestic bridge swivel construction process, the bridge swivel steel support is generally used for one-time use. After the bridge swivel is completed, the steel support and the girder body are poured as a whole. [0003] For example, in the patent application CN201420521212.X, there is a lower ball seat for a detachable bridge swivel steel bearing. The bridge swivel steel support includes an upper spherical hinge and a lower spherical hinge that mesh with each other. The lower spherical hinge is fixed to the lower ball seat by bolts. The upper and upper ball hinges are fixed to the lower part of the beam body by bolts, and the lower ball seat is fixed to the lower cap or the top of the pier. After the construction of the beam bod...
