Embodiment Construction
[0036] to combine figure 1 , figure 2 It can be seen that the high-speed railway bridge assembly-type steel plate shear wall damping device disclosed in this embodiment includes multiple sets of damping units arranged around the support at the center of the top of the pier column.
[0037] to combine Figure 1 to Figure 3 It can be seen that each group of damping units includes two sets of T-shaped main body 1 and its connected horizontal energy-dissipating plate 2, angle steel 3, anchor member 4 and fastener assembly components. Relatively arranged, the vertical energy dissipation plate 5, angle steel 3 and fasteners are connected to form an integral part with an I-shaped cross-section of the assembled main structure.
[0038] to combine image 3 and Figure 4 It can be seen that the top surface of the wing plate of the T-shaped main body 1 is symmetrically connected with two rows of anchor members 4 with respect to its longitudinal center plane, and the horizontal energ...
