Example Embodiment

[0033] Example 1

[0034] like figure 1 As shown, the self-reset viscous energy-dissipating support based on the disc spring provided in this embodiment is formed by combining an energy-dissipating component and a self-resetting component.

[0035] Energy dissipation part: the viscous damper (3) is fixed on the inner side of the outer casing (4), the inner casing (5) is fixed on the left end plate (1), and the outer casing (4) is fixed on the right end plate (2) , when the support member is under tension or compression, the outer sleeve (4) and the inner sleeve (5) slide relative to each other, and the viscous damper (3) begins to consume energy.

[0036]The self-reset part: an inner stopper (7), a stopper (8) and an outer stopper (9) are provided at both ends of the gap between the outer sleeve (4) and the inner sleeve (5). The inner stopper (7) is sleeved on the inner sleeve (5) and is fixedly connected with the inner stopper (5). An outer stopper (9) is arranged outside t...

Abstract

The invention provides a self-resetting viscous energy dissipation support based on a disc spring, and belongs to the technical field of civil engineering disaster prevention and shock absorption. The self-resetting viscous energy dissipation support is formed by combining a viscous damper and the combined disc spring in parallel and is mainly composed of a left end plate, a right end plate, the viscous damper, an outer sleeve, an inner sleeve, the combined disc spring, an inner stop block, baffles and an outer stop block; and the viscous damper is fixedly connected to the inner side of the outer sleeve, the inner sleeve is a piston rod of the viscous damper and is connected with the left end plate, and the outer sleeve is fixedly connected with the right end plate. The combined disc spring is arranged on the inner sleeve in a penetrating and sleeving manner and is arranged between the baffles. According to an energy dissipation device based on the combined disc spring and the viscous damper, the outer sleeve and the inner sleeve relatively slide, then the inner stop block and the outer stop block are driven to push the baffles to slide in the opposite directions, finally, the combined disc spring is extruded, and therefore the combined disc spring is in the pressed state all the time no matter whether the device is pulled or pressed. The support can guarantee the deformation and bearing force requirements of the structure under the earthquake action, and the earthquake resistance of the structure is improved.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of civil engineering, and is an energy-dissipating and shock-absorbing component applied in the field of structure and bridge engineering. The self-resetting viscous energy-dissipating support based on disc springs has good energy-dissipating and self-resetting capabilities. Background technique [0002] In recent years, frequent earthquakes have brought serious threats to people's lives and property safety, making more and more scholars pay attention to and promote the development of structural anti-seismic technology. Earthquakes can cause serious damage to structures, especially large earthquakes, which can lead to structural collapse. Although the traditional support increases the lateral stiffness of the structure to a certain extent, it is only limited to this aspect. It is easy to cause damage and failure of itself and the connection under the action of a large earthquake cycle load. ...
