Problems solved by technology

However, the shear force of the limit device in this damping method is uncertain, and it is also prone to fatigue damage in normal times. It needs to be inspected and replaced regularly, which is extremely inconvenient for bridges.
[0004] Especially for cable-stayed bridges, steel bridges, etc. affected by strong winds, the support of the limit device is very easy to generate fatigue under the long-term wind load and braking load, resulting in fatigue damage of the limit device , cannot play the role of limiting bridge displacement

Embodiment

[0033] see figure 1 and figure 2 , figure 1 It is a structural schematic diagram of the damping support 10 provided by the embodiment of the present invention when it is applied to the bridge 100 . figure 2 A structural schematic diagram of the damping support 10 provided by the embodiment of the present invention when it is applied to the bridge 100 in another way. In the figure, the direction indicated by the A arrow is the direction A of the longitudinal bridge, and the direction indicated by the B arrow is the direction B of the horizontal bridge.

[0034] The embodiment of the present invention provides a damping support 10, and the damping support 10 has the characteristics of stable operation. The damping support 10 can be applied to various types of bridges 100 and the like. When the damping bearing 10 is applied to the bridge 100, the bridge 100 connects the beam body 20 and the bridge pier (not shown) through the damping bearing 10, and the bridge 100 may inclu...

Abstract

The invention discloses a damping support, and relates to the technical field of bridge structure engineering. The damping support comprises a support body and a plurality of damping elements. The support body comprises a sliding plate and a piston. The sliding plate is slidably connected with the piston, and the damping element is connected with the sliding plate and the piston and can damp and dissipate energy when the sliding plate displaces relative to the piston. The multiple damping elements are distributed on the periphery of the piston, the number of the damping elements is an even number, and the damping elements are symmetrically arranged in pairs relative to the axis of the piston. The damping support has the advantage of being stable in work.

Description

technical field [0001] The invention relates to the technical field of bridge structure engineering, in particular to a damping support. Background technique [0002] In the existing bridge structure, common loads such as temperature load and aerodynamic load are generally adjusted by setting movable bearings. However, when the bridge encounters excessive loads such as strong winds and earthquakes, the movable bearings will undergo a large displacement, thereby Cause damage to the bridge structure, even falling beams and other dangers. [0003] For bridges with shock-absorbing bearings, it is usually necessary to set a limit device on the fixed pier to limit the displacement of the support under normal loads; under the action of earthquake load, the limit device is destroyed, and the shock-absorbing device enters the working state. Play the role of shock absorption and energy consumption. However, the shear force of the limit device in this damping method is uncertain, and...
