Problems solved by technology

[0003] In the above-mentioned scissor structure, the rate and displacement amplification of the damper are always changing with the displacement of the structure, so it is inconvenient to consider the effect of the damper during design
However, using the leverage 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.

[0036] At least 2 folding units (2-1) arranged in parallel are installed between the first plate (5-1) and the second plate (5-2), and each folding unit (2-1) includes: a first folding bar ( 2-1-1), the second folding rod (2-1-2), one end of the first folding rod (2-1-1) is hingedly conn...

Embodiment 2

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

[0047] The space folded viscous damper of the present invention has the advantage that it can be equipped with multiple oil cylinder type viscous dampers, which is actually equivalent to integrating several plane folded dampers, compared with a single plane folded viscous damper. Type damper, which enhances the stability and integrity of the damper. At the same time, compared with several planar folded dampers (each damper needs to be connected to the structure separately), the space folded viscous damper, Many components are reduced and space is saved.

Embodiment 3

[0048] Embodiment 3: as Figure 5 As shown, 5 folding units and 2 cylinder viscous dampers are hinged between the first plate and the second plate. The arrangement of the folding units and the cylinder viscous dampers is: 2 folding units + 1 cylinder Viscous damper + 1 folding unit + 1 cylinder type viscous damper + 2 folding units, between the 2 folding units on both sides, the connecting rod between the first folding rod and the connecting rod between the second folding rod are set , the advantage of the spatially folded viscous damper is that the folding unit and the structural connection unit can be configured according to the characteristics of the structure.

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 anti-seismic buildings, in particular to a space-folding viscous damper and an energy-dissipating mechanism in a frame structure. Background technique [0002] Viscous dampers are directly related to velocity and displacement. Many scholars have conducted research on increasing the rate or displacement of the damper, which can be divided into the following three categories: first, the principle of leverage, such as CN203742014U, CN106284726A, and CN105735508A, uses the principle of leverage to amplify the displacement between structural components; second, Scissors structure, such as CN105178468A, CN106088386A, CN202731008U, is to utilize quadrilateral deformation substantially, the deformation of another diagonal caused by the deformation of one diagonal; the 3rd, utilize gear set to change speed, displacement, as CN105735508A . [0003] In the above-mentioned scissor structure, the speed a...
