The design of the splint allows multiple steel plates to be fastened together to form an integral structure.
[0031] Furthermore, corresponding first bolt holes 71 are provided on the first steel plate 81, the first clamping plate 83 and the first I-beam 1 (i.e., the positions of the first bolt holes 71 on the first steel plate 81, the first bolt holes 71 on the first clamping plate 83 and the first I-beam 1 are the same), and the first bolts penetrate through each row of first bolt holes 71 at the same position in sequence and are threadedly connected to the nuts, thereby simultaneously fixing one end of the first damper core 3 and one end of the second damper core 4 on the first I-beam 1; corresponding second bolt holes 72 are provided on the second steel plate 82, the second clamping plate 84 and the second I-beam 2 (i.e., the positions of the second bolt holes 72 on the second steel plate 82, the second bolt holes 72 on the second clamping plate 84 and the second I-beam 2 are the same), and the second bolts penetrate through each row of second bolt holes 72 at the same position in sequence and are threadedly connected to the nuts, thereby simultaneously fixing the other end of the first damper core 3 and the other end of the second damper core 4 on the second I-beam 2.

[0037] During operation, under the action of external force, the first node plate 5 and the second node plate 6 will produce relative displacement up and down, so that the first damper core 3 and the second damper core 4 in the middle are subjected to shear force, resulting in the first steel plate 81 and the second steel plate 82 being fastened by the first bolt hole 71 and the second bolt hole 72, and the first I-beam 1 and the second I-beam 2 are displaced the same, and then the metal rubber 85 between the first steel plate 81 and the second steel plate 82 will produce shear deformation; when the metal rubber 85 produces shear deformation, the internal metal wires will rub against each other to dissipate a large amount of energy, thereby achieving the purpose of shock absorption and energy consumption.
