Abstract

The invention provides a detachable lower ball seat for a high-speed bridge swivel steel bearing, relates to the technical field of bridge construction, and solves the problem that the existing detachable lower ball seat for a bridge swivel steel bearing needs to be disassembled. It is extremely difficult to jack up the bridge first and then to be disassembled, and the bridge is jacked up and then dropped, which also makes the bridge a great safety hazard, and there may be deviations in the position, including the lower ball seat; The upper end of the lower ball seat is horizontally equipped with a lower ball joint. In the present invention, because the left end edge and the right end edge of the lower ball seat are respectively fixed with horizontal side support plates, they can also play a fixed role at the same time, and when the construction is completed, the squeeze block and self-unloading can be made The blocks are separated, so that the lower ball joint part falls, so that there is a gap between the device and the bridge, which can be withdrawn freely. In summary, the device is safer and more efficient when used, and the reuse rate is extremely high.

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...
