Embodiment 1

[0041] A two-way large-displacement variable damping viscous damping wall device proposed in this embodiment, such as figure 1 As shown, it includes an upper damping rod 10, an upper damping rod outer barrel 11, an upper damping oil barrel 12, a lower damping rod 20, a lower damping rod outer barrel 21, a lower damping oil barrel 22 and a guide rail base 30; wherein, the upper damping oil barrel 12 is connected and fixed together with the lower damping rod 20 up and down; the upper damping rod 10 is inserted on the upper damping rod outer barrel 11, and can move along the first direction in the upper damping rod outer barrel 11; the upper damping rod outer barrel 11 is installed In the upper damping oil barrel 12, and can move along the first direction in the upper damping oil barrel 12; the lower damping rod 20 is inserted on the lower damping rod outer barrel 21, and can move in the lower damping rod outer barrel 21 Movement in two directions; the lower damping rod outer bar...

Embodiment 2

[0048] The difference between the second embodiment and the first embodiment is that, on the basis of the first embodiment, the second embodiment also includes a roller system 40, please refer to figure 1 , the roller system 40 is mounted on the bottom of the upper damping oil barrel 12 and placed on the guide rail base 30 , and it can move along the second direction on the guide rail base 30 .

[0049] The main functions of the roller system 40 are two, one is to support the upper damping oil barrel 12, the upper damping rod 10, and the upper damping rod outer barrel 11, and the other is to facilitate the realization of the upper damping oil barrel 12 ( (together with the damping rod 10 and the upper damping rod outer barrel 11) move along the second direction in the guide rail base 30 to achieve a better shock resistance effect.

[0050] It can be understood that the second embodiment includes the beneficial effects of the first embodiment.

Embodiment 3

[0052] The embodiment is a further improvement and specific design made on the basis of the first embodiment or the second embodiment.

[0053] In this embodiment, a base channel 31 is provided on the guide rail base 30 along the second direction (see figure 1 or Figure 15 ); the outer wall of the upper damping oil barrel 12 is provided with the outer channel 13 of the upper damping oil barrel along the second direction (see Figure 7 to Figure 10 ); the outer channel 13 of the upper damping oil drum is installed in alignment with the channel 31 of the base, and can slide relatively;

[0054] The inner wall of the upper damping oil barrel 12 is provided with an inner channel 14 of the upper damping oil barrel along the first direction (see Figure 7 ); the outer wall of the upper damping rod outer barrel 11 is provided with an upper viscous oil retention hole 15 and an upper damping rod outer barrel channel 16 along the first direction (see figure 2 ); the channel 16 of t...

Abstract

The invention relates to a two-way large displacement variable damping viscous damping wall device, comprising an upper damping rod, an upper damping rod outer barrel, an upper damping oil barrel, a lower damping rod, a lower damping rod outer barrel, a lower damping oil barrel and a guide rail base; Wherein, the upper damping oil drum and the lower damping rod are connected up and down and fixed together; the upper damping rod is inserted on the outer drum of the upper damping rod, and can move along the first direction in the outer drum of the upper damping rod; the outer drum of the upper damping rod is installed In the upper damping oil barrel, and can move along the first direction in the upper damping oil barrel; the lower damping rod is inserted on the lower damping rod outer barrel, and can move in the second direction in the lower damping rod outer barrel; the lower damping rod The outer barrel is installed in the lower damping oil barrel and can move in the second direction in the lower damping oil barrel; the upper damping oil barrel is installed on the guide rail base and can move in the second direction in the guide rail base. The invention does not hinder the shock-absorbing effect of the shock-isolation support during small or moderate earthquakes, and can cooperate with the shock-isolation support to protect the shock-isolation layer during large earthquakes.

Description

technical field [0001] The invention relates to the field of building shock isolation, in particular to a two-way large displacement variable damping viscous damping wall device, which can realize constant variable damping or intermittent variable damping, and can be applied to building shock isolation layers and bridges in construction engineering or bridge engineering Seismic isolation layer and equipment isolation layer, etc. Background technique [0002] In the isolation layer, the viscous damping wall and the rubber isolation bearing are used at the same time to better reduce the earthquake effect. At the same time, in the event of a large earthquake, the cross-sectional area of ​​the viscous damping wall is much larger than that of the cylindrical viscous damper. , its energy dissipation effect is much greater than that of the latter, and it can significantly reduce the displacement of the isolation layer by working together with the rubber isolation bearing. Accordin...
