Detailed Description
The invention is further described below with reference to examples and figures:
as shown in fig. 1, a secondary damping vibration attenuation device for high-rise building vibration attenuation comprises a primary damping device 1 and a secondary damping device 2, wherein the primary damping device 1 is one or more liquid dampers 11, the secondary damping device 2 comprises a frame body 21 fixed on a building, one or more layers of support panels 211 are horizontally arranged on the frame body 21, and the liquid dampers 11 are placed on the support panels 211 and can slide on the support panels 211 under the action of force under the action of friction resistance. The liquid damper 11 of the first-system damping device 1 has the function of generating damping effect by the vibration and flow of damping liquid in the damper when the building slightly vibrates, so that the device can generate energy absorption and vibration reduction effects when encountering low-intensity vibration. The secondary damping device 2 is arranged to set proper static friction force between the liquid damper 11 and the support panel 211, when the vibration intensity reaches a certain level and breaks through the static friction force, the liquid damper 11 slides on the support panel 211 with friction resistance, so that the secondary damping device 2 can play a damping role when encountering high-intensity vibration (the liquid damper 11 still plays a damping role at this stage), and can absorb the vibration kinetic energy better and damp the vibration amplitude when encountering high-intensity vibration. Therefore, the secondary damping vibration reduction equipment can effectively cope with the whole process of the protected building from low-intensity vibration to high-intensity vibration, and vibration reduction and disaster prevention are realized.
Example 1
As shown in fig. 2, the liquid damper 11 includes: a container 111 and a partition 112, wherein the partition 112 is provided with a damping hole 113. A tube 114 is arranged in the center of the container 111, and a plurality of baffles 112 and other arc lengths are radially fixed on the outer wall of the tube 114; the side wall and bottom of the barrel 114 are sealed, and the interior space of the barrel 114 is independent of the space of the container 111.
The partition 112 divides the container 111 into a plurality of liquid containing spaces 115. The damping fluid in one fluid containing space 115 can flow into the adjacent fluid containing space 115 through the damping holes 113 on the partition 112. When the container 111 shakes due to vibration, damping liquid flows through the damping holes 113 under a certain pressure to generate a damping effect, and part of vibration kinetic energy is converted into heat energy, so that energy absorption and vibration reduction are realized.
The side wall and the bottom of the cylinder 114 are sealed, so that the inner space of the cylinder 114 is independent of the liquid containing space 115, and the natural frequency of the whole liquid damper can be changed by adding liquid with different depths into the cylinder 114, so that the natural frequency of the whole liquid damper is corresponding to the protected object, and the damper has a wider frequency adapting range.
Example two
As shown in fig. 3 and 4, the difference from the first embodiment is that the lower end of the cylinder 114 of the liquid damper 11 is mounted at the bottom off the center of the container 111 by a bearing 116; at least one of the plurality of baffles 112 has a length that is greater than the length of the other baffles 112. In this way, when vibration starts, the water pressure received by one baffle plate 112 with a large length is larger than the water pressure received by other baffle plates 112 with shorter lengths, so that the baffle plates 112 with large lengths are forced to rotate like a rudder towards the shaking direction of the damper, the left and right adjacent baffle plates 112 can intercept the shaking liquid flow positively, and the liquid flow can pass through the damping holes 113 on the front interception baffle plates 112 more stably.
Example III
As shown in fig. 5 and 6, the liquid damper 11 is directly placed on the support panel 211;
the bottom plate of the liquid damper 11 is pressed against the support panel 211 and slides against the support panel 211 with frictional resistance.
The principle of application is that when the vibration intensity is continuously increased, the frame 21 is strongly swayed with the building, and the sliding seat 22 together with the liquid damper 11 placed thereon causes the liquid damper 11 to slide relatively with respect to the support panel 211 of the swayed frame 21 due to the stationary inertia which remains in place. According to the mechanics principle, we can see that the frame body 21 and the support panel 211 thereof are kept in a static state, and the sliding seat 22 and the liquid damper 11 placed thereon are subjected to horizontal force, so that the sliding seat 22 and the liquid damper 11 can slide on the support panel 211.
According to the static friction force preset between the liquid damper 11 and the support panel 211, a proper material is selected to make the bottom plate of the liquid damper 11 and the support panel 211 with proper friction coefficients.
The frame 21 on the outer periphery of the support panel 211 is provided with an upward-standing stroke limit edge 212, and a distance between the liquid damper 11 and the stroke limit edge 212, which satisfies the sliding stroke of the liquid damper 11, is provided. A plurality of return springs 225 for automatically returning the liquid damper 11 to the center of the support panel 211 are provided between the stroke limit edge 212 and the liquid damper 11. One end of the return spring 225 is connected to the liquid damper 11, and the other end of the return spring 225 is connected to the inner side of the stroke limit edge 212.
Example IV
As shown in fig. 7 and 8, the secondary damping device 2 is different from the third embodiment in that the secondary damping device 2 further includes a sliding seat 22, the sliding seat 22 has a positive pressure seat plate 221, the positive pressure seat plate 221 is pressed on the support panel 211 and can slide on the support panel 211 under friction resistance, and the liquid damper 11 is placed on the support panel 211 and the liquid damper 11 is placed on the sliding seat 22.
A positive pressure seat plate 221 having a suitable friction coefficient is made by selecting a suitable material according to a static friction force preset between the liquid damper 11 and the support panel 211.
The advantage of this arrangement is that the bottom plate of the liquid damper 11 can be made of common materials.
Example five
As shown in fig. 9 and 10, the sliding seat 22 is different from the fourth embodiment in that the back pressure plate 222 is further provided with a back pressure plate 222, a circular stroke limit hole 213 is provided in the center of the support panel 211, the upper surface of the back pressure plate 222 is pressed against the lower surface of the support panel 211, a cylindrical limit connector passing through the central stroke limit hole 213 of the support panel 211 is provided between the central position of the back pressure plate 222 and the central position of the positive pressure seat plate 221, and the diameter of the limit connector is smaller than the diameter of the stroke limit hole 213. In this way, the positive pressure seat plate 221 and the back pressure plate 222 can be integrally connected, and can synchronously slide on the upper and lower surfaces of the support panel 211, respectively, and the sliding stroke thereof is limited by the stroke limiting hole 213. Here, the back pressure plate 222 is not only used to increase the friction resistance between the sliding seat 22 and the support panel 211, but also used to control the positive pressure seat plate 221 on the support panel 211 during sliding, so as to avoid the sliding seat 22 and the liquid damper 11 placed thereon from toppling during severe shaking.
In order to reset the sliding seat 22 deviating from the center of the support panel 211 during sliding in time, a reset spring 225 for pulling the sliding seat 22 back to the center of the support panel 211 is radially arranged between the periphery of the limit connecting piece and the inner wall of the travel limit hole 213 at equal intervals. One end of the return spring 225 is connected to the connecting member, and the other end of the return spring 225 is connected to the inner wall of the stroke limiting hole 2131.
The limit connecting piece is a limit bolt 223 with a bolt handle 2231 at the lower end and an external thread at the upper end; the center of the lower bottom surface of the positive pressure seat plate 221 is provided with a threaded hole 2211, and the threaded hole 2211 is provided with an internal thread matched with the external thread of the limit bolt 223; the center of the counter plate 222 is provided with a non-threaded through hole, and the limit bolt 223 is screwed into the threaded hole 2211 from the bottom of the counter plate 222 upwards through the non-threaded through hole and the travel limit hole 213 until the bolt handle 2231 presses the counter plate 222 against the lower surface of the support panel 211. An elastic gasket 224 sleeved outside the screw rod of the limit bolt 223 is arranged between the counter plate 222 and the bolt handle 2231. The elastic pad 224 is an arch pad with axial expansion and contraction elasticity, and can axially compress the arch pad when the bolt handle 2231 is fastened, so that the bolt always maintains a pretightening force, and further the counter pressure plate 302 always is in a state of pressing the support panel 211.
The above embodiments are only for the purpose of more clearly describing the present invention and should not be construed as limiting the scope of the present invention, and any equivalent modifications should be construed as falling within the scope of the present invention.
