Referring to fig. 1, the present embodiment provides a friction viscous damping wall, which includes a damping case 100, a shear plate 200, a driving friction mechanism 300, a driven friction mechanism 400, and an elastic damping mechanism 500.
The bottom of the damping box 100 can be connected with the bottom beam 010, and the top of the shear plate 200 can be connected with the top beam 020; the damping tank 100 contains a viscous fluid that provides a viscous force, and the shear plate 200 is immersed in the viscous fluid while being deep into the damping tank 100;

The friction viscous damping wall in this embodiment includes a damping case 100, a shear plate 200, a driving friction mechanism 300, a driven friction mechanism 400, and an elastic damping mechanism 500. Wherein, the damping box 100 and the shear plate 200 realize energy consumption effect through viscous damping, and the driving friction mechanism 300 and the driven friction mechanism 400 are matched relatively to realize friction energy consumption. So through viscous damping and friction damping cooperation in order to realize better energy consumption effect to ensure damping capacity. Further, in this embodiment, an elastic damping mechanism 500 is disposed between the damping case 100 and the shear plate 200 to achieve buffering and energy consumption. Therefore, the combination of more energy consumption modes is realized, so that the effect of the damping wall is ensured, and the stability and the reliability of the building are ensured.
Referring further to fig. 1 and 2, it can be seen that in the present embodiment of the utility model, the elastic damping mechanism 500 includes a damping unit 510 and an elastic unit 520; along the length direction of the shear plate 200, both ends of the damping unit 510 are respectively disposed between the shear plate 200 and the damping tank 100 to buffer the relative movement of the shear plate 200 and the damping tank 100; and elastic units 520 are respectively provided between the shear plate 200 and the damper case 100 in the length direction of the shear plate 200 to buffer the relative movement of the shear plate 200 and the damper case 100 by elasticity.
Namely, the elastic damping mechanism 500 has two energy consumption modes of damping energy consumption and elastic energy consumption, viscous damping and friction damping, and the cooperative cooperation of the four energy consumption modes can ensure that the building can consume relative displacement under earthquake waves, dissipate earthquake energy and protect the safety of the building under the earthquake.
Optionally, the elastic damping mechanism 500 further comprises a support structure 530, the support structure 530 comprising opposite first and second ends 531, 532; the first end 531 of the support structure 530 is connected to the damper box 100, and the second end 532 extends to one side of the shear plate 200 in the length direction; one end of the damping unit 510 is disposed at the second end 532 of the support structure 530, and the other end of the damping unit 510 is disposed on the shear plate 200; the elastic units 520 are respectively abutted between the second ends 532 and the shear plates 200.
The elastic unit 520 is abutted between the support structure 530 and the shear plate 200, thereby buffering displacement between the shear plate 200 and the damper box 100, and thus guaranteeing stability of the building using elastic energy consumption. While the damping unit 510 absorbs energy by damping itself.
Alternatively, the damping unit 510 may be at least one of a liquid damper, a gas damper, and an electromagnetic damper. The damper is used for providing resistance to movement, so that movement energy is consumed, the effects of vibration reduction and energy dissipation are achieved, and the safety of shock absorption objects is further guaranteed.
Further, in the present embodiment of the present utility model, the damping unit 510 includes a fixed block 511 and a movable block 512, the movable block 512 being telescopically disposed in the fixed block 511; and a fixed block 511 is provided on the shear plate 200, and a movable block 512 is connected to the damper case 100. The damping unit 510 of the telescopic structure can secure the effect of the damper.
As can also be seen from the figure, damping units 510 are detachably provided on the shear plate 200 and the damping tank 100, respectively. Specifically, the damping unit 510 can be easily detached from the shear plate 200 and the damping tank 100, thereby facilitating maintenance and servicing of the elastic damping mechanism 500.
Alternatively, in the present embodiment of the present utility model, both ends of the damping unit 510 are hinged to the shear plate 200 and the damping tank 100, respectively. The hinged arrangement of the damping unit 510 allows for a better flexibility of movement of the elastic damping mechanism 500 with the shear plate 200 and the support structure, thereby avoiding damage to the damping unit 510 caused by a rigid connection.
In the present embodiment of the utility model, the elastic unit 520 is a compression spring. The compression spring has the advantages of simple structure and lower cost, and can adapt to the scene of large-scale assembly line manufacturing. Further, the elastic unit 520 is sleeved on the circumferential direction of the damping unit 510, and one end of the elastic unit 520 abuts against the second end 532 of the supporting structure 530, and the other end abuts against the side wall of the shear plate 200, so as to ensure the elastic energy dissipation effect of the elastic damping mechanism 500 through elastic force.
In the present embodiment of the present utility model, the shear plate 200 has a center line 201 in a length direction, and the driven friction mechanism 400 includes a first friction unit 410, a second friction unit 420, and a third friction unit 430 disposed in this order from the center line 201 to an edge of the shear plate 200; and the friction coefficients of the first friction unit 410, the second friction unit 420, and the third friction unit 430 are sequentially increased.
Namely, the driven friction mechanism 400 disposed on the inner wall of the damper case 100 is divided into three parts of a first friction unit 410, a second friction unit 420 and a third friction unit 430, the friction coefficients of which are sequentially increased. When the shear plate 200 is driven by the seismic waves to move to two sides along the center line 201, the center of the active friction plate on the shear plate 200 will generate relative friction with the first friction unit 410, the second friction unit 420 and the third friction unit 430 in sequence, and the purposes of vibration reduction and energy dissipation are achieved in a friction energy consumption mode; meanwhile, as the friction coefficients of the three parts are sequentially increased, when the vibration wave amplitude is larger, the displacement of the center of the active friction plate is larger, the friction force born by the active friction plate is larger, the generated friction energy consumption is more obvious, and the vibration reduction and energy dissipation effects are more obvious.
Further, in the present embodiment of the present utility model, the thicknesses of the first friction unit 410, the second friction unit 420, and the third friction unit 430 sequentially increase from the centerline 201 to the edge of the shear plate 200. As the thickness of the driven friction mechanism 400 increases, when the center of the driving friction plate on the shear plate 200 generates relative friction with the first friction unit 410, the second friction unit 420 and the third friction unit 430 in sequence, the larger the displacement of the center of the driving friction plate is, the larger the friction force is, and the more obvious the friction energy consumption is generated.
Optionally, the surface of the second friction unit 420 is provided with grid patterns 401, and the surface of the third friction unit 430 is provided with spiral patterns 402. That is, the roughness of the first, second and third friction units 410, 420 and 430 increases in sequence, so that the greater the displacement of the center of the active friction plate, the greater the friction force is received.
When in use, the bottom of the damping box 100 is connected with the bottom beam 010, and the top of the shearing plate 200 is connected with the top beam 020; the damping tank 100 is filled with a viscous fluid providing a viscous force, and the shear plate 200 is immersed in the viscous fluid while being deep into the damping tank 100; the driving friction mechanism 300 and the driven friction mechanism 400 are in abutting fit; the elastic damping mechanism 500 is disposed between the damping tank 100 and the shear plate 200, respectively, through the support structure 530. When the shear plate 200 and the damping case 100 have a relative movement tendency, the damper consumes energy, and the elastic energy, viscous damping and friction damping cooperate to jointly achieve the effects of vibration reduction and energy dissipation.
The friction viscous damping wall provided by the embodiment has at least the following advantages:
The friction viscous damping wall of the scheme has the advantages that the friction plate consumes energy, so that the speed type and displacement type energy consumption is realized; the combination of more energy consumption modes is realized, so that the effect of the damping wall is ensured, and the stability and the reliability of a building are ensured.
