Example Embodiment

[0026] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0027] Such as figure 1 with figure 2 As shown, a multifunctional viscous damper includes a cylinder barrel 11, a piston rod 12, and a piston 13. Both ends of the cylinder barrel 11 are provided with end caps 14 respectively, and two ends of the piston rod 12 respectively pass through. The end cover 14 is provided with an ear plate 26 at one end of the piston rod 12, the cylinder barrel 11 is sheathed with a shield 28, and a number of anchor rods 25 are symmetrically arranged around the shield 28. The end cover 14 and the shield 28 pass The anchor rod 25 is tightly connected. The piston 13 is fixedly sleeved on the piston rod 12 and movably arranged in the cylinder 11. The piston 13 divides the cylinder 11 into two chambers 21, and the two chambers 21 are filled with a damping medium 20. A dynamic seal 23 is provided between the two end covers 14 and the pi...

Abstract

The invention provides a multifunctional viscous damper and a connecting method of the multifunctional viscous damper, and relates to the technical field of a bridge. End covers are respectively arranged at the two ends of a cylinder tube, the two ends of a piston rod respectively penetrate out of the end covers arranged at the two ends, a piston is fixedly arranged at the piston rod in a sheathing way and is movably arranged in the cylinder tube, two cavities are fully filled with damping media, a positive damping valve of the first end cover is communicated with a positive damping valve of the second end cover through a positive oil path, a reverse damping valve of the second end cover is communicated with a reverse damping valve of the first end cover through a reverse oil path, and the positive oil path and the reverse oil path are respectively provided with valves. According to the connecting method, a lug seat is arranged on a main beam or an upper support seat plate connected with the main beam, a table seat is arranged on the top surface of a pier, the multifunctional viscous damper is arranged in an annular hoop arranged on the table seat, and the connection between the main beam and the pier is realized. The multifunctional viscous damper and the connecting method have the advantages that the shock absorption, locking and jacking functions are realized, in addition, small required installation space is ensured, and the stability is good.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a multifunctional viscous damper and a connection method thereof. Background technique [0002] In recent years, earthquake disasters have occurred frequently, and the anti-seismic devices of large-span civil engineering structures have attracted much attention from the industry. The anti-seismic devices used in civil engineering structures include metal dampers, friction dampers, viscous dampers, and viscoelastic dampers. . Among them, the viscous damper has the advantages of full hysteretic curve, strong energy dissipation capacity, and extremely small static stiffness, and is widely used. However, the currently used viscous dampers have a single function and are only used for the seismic resistance of the bridge in the completed state. During the construction of the bridge, additional construction devices are needed to realize the locking and pushing of the bridge. For examp...
