Embodiment 1
[0038] Such as Figure 1 to Figure 5As shown, a sway self-resetting shock absorbing system for the central column of an underground station includes a central column 1 and a top plate 2 and a bottom plate 3 directly connected to the central column 1. The top plate 2, the central column 1 and the bottom plate 3 pass through The knotted prestressed steel strands 4 are connected into a whole, the unbonded prestressed steel strands 4 pass through the center of the center column 1 vertically, and the upper ends of the unbonded prestressed steel strands 4 are anchored to the top plate 2 through anchors 5 The upper and lower ends are anchored to the bottom of the bottom plate 3 through the anchorage 5; the upper end of the central column 1 has a hemispherical upper raised joint 101 and a steel backing plate 7 with hemispherical protrusions, and the corresponding position of the lower end of the top plate 2 is reserved with a hemispherical The lower end of the center column 1 has a he...
Embodiment 2
[0050] The basic structure and method of this embodiment are the same as those of Embodiment 1, and the similarities will not be described in detail. The difference is:
[0051] The top plate 2 and the bottom plate 3 are constructed by cast-in-place method, and the specific steps are as follows:
[0052] a The center column 1 is constructed by factory prefabrication and on-site assembly, the center of which uses corrugated pipes to reserve unbonded prestressed steel strand holes, and the hook end of the center column pre-embedded steel plate 8 is pre-embedded at the designed position. The hemispherical protruding steel backing plate 7 is correspondingly pre-embedded at the top and bottom of the center column 1. After the concrete is poured and prefabricated, the steel backing plate 7 is adhered to the top and bottom of the center column 1 to form a whole with the center column 1;
[0053] b Base plate 3 is cast-in-place construction, the hook end of base plate pre-embedded ste...
