Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] Figure 1 to Figure 2 The reference numerals in the figure are: upper seat 1; upper groove 11; limit column 12; alignment groove 13; first vulcanized rubber layer 14; curved plate 2; curved convex portion 21; ; Lower groove 31; Limit hole 32; Alignment bump 33;
[0022] Such as Figure 1 to Figure 2 As shown, a curved surface laminated steel plate self-resetting friction damping support includes an upper seat 1, a lower seat 3 and a curved plate 2 between the upper seat 1 and the lower seat 3, and the curved plate 2 has at least two And stacked up and down, the curved panel 2 at the lowermost end is arranged on the lower seat 3, the curved panel 2 at the uppermost end is in contact with the upper seat 1 and supports the upper seat 1, and the upper seat 1 is in contact with the upper seat 1. Supported by the curved panel 2, it hangs ab...

The invention provides a curved-surface stacked-steel-plate self-restoration friction damping support. The support comprises an upper base, a lower base and curved-surface plates located between the upper base and the lower base, wherein the at least two curved-surface plates are arranged in a vertically-stacked mode, the curved-surface plate located at the bottommost end is arranged on the lower base, and the curved-surface plate located at the uppermost end makes contact with the upper base and is used for supporting the upper base. The support has the advantages that due to the fact that the curved-surface plates are arranged in a stacked mode, a curved-surface friction pair is formed between every two adjacent curved-surface plates, the curved-surface plate located at the uppermost end and the upper base can form a second friction pair, the curved-surface plate located at the bottommost end and the lower base can form a third friction pair, vehicle impact and seismic energy are consumed through mutual friction between the curved-surface plates arranged in the stacked mode, self-restoration is achieved through the self-restoration capacity of the curved-surface plates, the structural mode is simple, the force transfer mechanism is clear, cost is low, the damping effect is stable, durability is good, and particularly, the damping effect on supports greatly influenced by vehicle impacting loads is remarkable.
Description
technical field [0001] The invention relates to the field of bridge structure vibration reduction, in particular to a curved surface laminated steel plate self-resetting friction vibration reduction support in the field of bridge structure vibration reduction. Background technique [0002] As the link of economic development, bridges play an irreplaceable role in the economic revitalization of our country, especially in the economic development of the western mountainous areas. As the connection and force transmission components of the upper and lower structures of bridge engineering, the mechanical properties of bridge supports directly affect the overall stability and safety of the bridge. [0003] Bridge bearings are mainly affected by the loads transmitted from the upper and lower structures. Aiming at how to weaken the influence of lower loads (mainly earthquake loads), scholars at home and abroad have carried out a lot of research and achieved rich research results, a...
