[0032] A bridge support, such as Figure 1 and Figure 2 As shown, it includes a support body 2, two bridge bodies 1 respectively arranged at both ends of the support body 2, and a plurality of viscous dampers 3 arranged around the support body 2, and the ends of the viscous dampers 3 are connected to the bridge body 1, as shown in FIG. Figure 5 As shown, in order to improve the connection stability of the viscous damper 3, the viscous damper 3 is connected to the bridge body 1 through the mounting plate 7, and preferably there are four viscous dampers 3, and the four viscous dampers 3 are respectively arranged at the four corners of the support body 2. When the bridge vibrates, the four viscous dampers 3 can evenly absorb and dissipate energy; the support body 2 and the viscous damper 3 are both covered with a protective cover 4. When in use, the support body 2 and the viscous damper 3 are both covered with a protective cover 4, which can form a more complete and balanced protection system, improve the overall resistance of the bridge structure, and ensure the long-term stability and safe operation of the bridge support.

[0033] In some embodiments, Figure 2 As shown, the support body 2 and the viscous damper 3 are both connected to the bridge body 1 through a connection structure; the connection structure includes a connection plate 51 provided with a first threaded hole, an embedded plate 52 provided with a second threaded hole, and a screw 53 passing through the first threaded hole and the second threaded hole in sequence, the embedded plate 52 is embedded in the bridge body 1, and the support body 2 and the viscous damper 3 are both connected to the connection plate 51. Since the embedded plate 52 is embedded in the bridge body 1, it can better transfer the load and ensure the strength and stability of the connection structure.

[0034] In some embodiments, the end of the protective sleeve 4 is connected to the connecting plate 51. By providing the protective sleeve 4 connected to the connecting plate 51, it is helpful to improve the sealing effect of the protective sleeve 4, effectively prevent moisture, dust and other pollutants from penetrating from the connecting part, and protect the internal structure from corrosion.

As a further improvement of this embodiment, Figure 4 and Figure 5 As shown, the protective cover 4 includes a first sub-body 41 and a second sub-body 42; one side edge of the first sub-body 41 is integrally connected to one side edge of the second sub-body 42, and the other side edge of the first sub-body 41 is detachably connected to the other side edge of the second sub-body 42, so as to facilitate the disassembly and assembly of the protective cover 4. In a specific embodiment, a fastener 43 is provided on each of the first sub-body 41 and the second sub-body 42, and a threaded hole is provided on the fastener 43. The first sub-body 41 and the second sub-body 42 are connected by bolts that pass through the threaded holes of the two fasteners 43 in sequence. The provision of the fastener 43 enables the protective cover 4 to fine-tune its own wrapping tightness.
