Problems solved by technology

[0003] In the above-mentioned scissor structure, the speed and displacement amplification of the damper are always changing with the displacement of the structure, so it is inconvenient to consider the function of the damper in the design
However, using the lever principle, although the rate and displacement magnification can be determined in advance, it can only be applied under the condition that the deformation direction is predicted.

Embodiment 2

[0046] Example 2: as Figure 3-4 As shown, between the two parallel first plates 5-1 and the second plates 5-2, there are 2×2 oil-cylinder viscous dampers arranged in a rectangular arrangement. The plates are hingedly connected with 3 folding units 2-1, the 3 folding units 2-1 are arranged in a row with the same spacing, and the centers of the 4 oil cylinder dampers are the same as the centers of the 3 folding units 2-1;

[0047] The advantage of the space-folding viscous damper of the present invention is that it can set up multiple oil-cylinder viscous dampers, which is actually equivalent to integrating several plane-folding dampers into one, compared with a single plane-folding viscous damper. At the same time, compared with several plane folding dampers (each damper needs to be connected with the structure separately), the space folding viscous damper, Many components are reduced and space is saved.

Abstract

The invention relates to a space foldable viscous damper. The space foldable viscous damper comprises folding units, oil cylinder type viscous damper bodies and structure connecting units, wherein each folding unit comprises a foldable rod which is hinged between a first plate and a second plate; two ends of each oil cylinder type viscous damper body are fixed between the first plate and the second plate; foldable rod connecting rods are arranged among the folding units; and the structure connecting units are connected with the foldable rod connecting rods. The space foldable viscous damper has the advantages that the oil cylinder type viscous damper bodies are integrated, and the damping and anti-seismic effect is improved. When the space foldable viscous damper is used in a frame structure, the oil cylinder type viscous damper bodies of the space foldable viscous damper are parallel to an upper beam, and therefore, the damping effect is maximum.

Description

technical field [0001] The patent of the present invention relates to the field of building earthquake resistance, in particular to a space folding viscous damper and an energy dissipation mechanism in a frame structure. Background technique [0002] Viscous dampers are directly related to velocity and displacement. Many scholars have conducted research on improving the rate or displacement of dampers, which can be divided into the following three categories: first, the principle of leverage, such as CN203742014U, CN106284726A, CN105735508A, uses the principle of leverage to amplify the displacement between structural members; second, Scissor-type structures, such as CN105178468A, CN106088386A, CN202731008U, essentially use the deformation of one diagonal caused by the deformation of the other diagonal when the quadrilateral is deformed; thirdly, the gear set is used to change the speed and displacement, such as CN105735508A . [0003] In the above-mentioned scissor-type s...
