[0035] The following description, with reference to the accompanying drawings, describes a three-dimensional vibration isolation support 1 based on a friction pendulum assembly according to an embodiment of the present invention.

[0036] like Figures 1-13 As shown, the friction pendulum combination three-dimensional vibration isolation support 1 according to an embodiment of the present invention includes a vertical vibration isolation device 10, a first connecting plate 20, a second connecting plate 30, a guide rod 40, a guide sleeve 50, and a friction pendulum assembly 60 (the up and down direction is shown by the arrow in the figure).

[0037] The vertical vibration isolation device 10 is adapted to undergo elastic deformation in the vertical direction. A first connecting plate 20 is located above the vertical vibration isolation device 10 and contacts its upper surface. A second connecting plate 30 is located below the vertical vibration isolation device 10 and contacts its lower surface. A guide rod 40 is connected to one of the first connecting plate 20 and the second connecting plate 30, and a guide sleeve 50 is connected to the other of the first connecting plate 20 and the second connecting plate 30. The guide sleeve 50 is a circular tube, and the guide rod 40 is slidably fitted within the guide sleeve 50, with a clearance fit between the inner surface of the guide sleeve 50 and the outer surface of the guide rod 40. The friction pendulum assembly 60 is disposed on at least one of the upper surface of the first connecting plate 20 and the lower surface of the second connecting plate 30. The friction pendulum assembly 60 includes at least a support plate 61 and a sliding plate 62. The support plate 61 is provided with a sliding friction surface 611, which is a concave curved surface. The sliding plate 62 is provided with a sliding layer 623, which is a convex curved surface and is slidably engaged with the sliding friction surface 611 so that the sliding plate 62 can slide relative to the support plate 61. The outer periphery of the support plate 61 is provided with a stop edge 612 for preventing the sliding plate 62 from disengaging from the sliding friction surface 611.

[0038] It is important to understand here that "the vertical vibration isolation device 10 is suitable for elastic deformation in the vertical direction" means that the vertical vibration isolation device 10 is suitable for elastic deformation under the action of forces in the vertical direction.

[0039] The skilled in the art can understand that when the friction pendulum combined three-dimensional vibration isolation support 1 is applied to a building project, the uppermost one of the first connecting plate 20, the second connecting plate 30 and the friction pendulum assembly 60 is connected with the superstructure of the building, the lowermost one of the first connecting plate 20, the second connecting plate 30 and the friction pendulum assembly 60 is connected with the substructure or foundation of the building, the friction pendulum assembly 60 can reduce the horizontal stiffness of the friction pendulum combined three-dimensional vibration isolation support 1, and the vertical vibration isolation device 10 can reduce the vertical stiffness of the friction pendulum combined three-dimensional vibration isolation support 1, so as to realize vibration isolation in the vertical and horizontal directions.

[0040] According to the friction pendulum combined three-dimensional vibration isolation support 1 provided in the embodiment of the present application, the vertical vibration isolation device 10 is provided, and the vertical vibration isolation device 10 is adapted to be elastically deformed in the up-down direction, so that the vertical vibration isolation device 10 has a smaller vertical stiffness and is adapted to bear the vertical load, the vertical vibration isolation device 10 is adapted to be compressed in the up-down direction, so that the overall vertical stiffness of the friction pendulum combined three-dimensional vibration isolation support 1 can be reduced, and the vertical natural vibration period of the vibration isolation system formed by the friction pendulum combined three-dimensional vibration isolation support 1 and the superstructure is small, and vertical vibration isolation is realized.

[0041] In addition, the friction pendulum assembly 60 is provided, the friction pendulum assembly 60 includes a support plate 61 and a sliding plate 62, the support plate 61 is provided with a sliding friction surface 611, the sliding friction surface 611 is a concave curved surface, the sliding plate 62 is provided with a sliding layer 623, the relative sliding of the support plate 61 and the sliding plate 62 can be realized through the sliding cooperation of the sliding friction surface 611 and the sliding layer 623, when horizontal vibration is borne, the sliding cooperation of the sliding friction surface 611 and the sliding layer 623 can eliminate the horizontal vibration, the vertical vibration isolation device 10 can remain horizontal in the sliding process, so that horizontal vibration isolation is realized, the vertical vibration isolation device 10 can continue to stably bear the vertical load, the friction pendulum combined three-dimensional vibration isolation support 1 can form a vibration isolation layer with smaller horizontal stiffness in the building, and the response of the ground horizontal vibration in the superstructure can be reduced.

[0042] That is, the friction pendulum assembly 60 and the vertical vibration isolation device 10 are provided, the horizontal vibration isolation can be realized through the friction pendulum assembly 60, the vertical vibration isolation can be realized through the vertical vibration isolation device 10, the vertical vibration isolation device 10 and the friction pendulum assembly 60 are integrated in the friction pendulum combined three-dimensional vibration isolation support 1 in a series connection mode, so that the friction pendulum combined three-dimensional vibration isolation support 1 can simultaneously realize horizontal and vertical vibration isolation, compared with the vibration isolation support which can only realize horizontal vibration isolation or only realize vertical vibration isolation in the related art, the friction pendulum combined three-dimensional vibration isolation support 1 can meet the vibration isolation requirements in different directions, and the vibration isolation effect and applicability of the friction pendulum combined three-dimensional vibration isolation support 1 are improved.

[0043] In addition, by arranging the guide rod 40 and the guide sleeve 50, the guide rod 40 is slidably arranged in the guide sleeve 50, and the inner surface of the guide sleeve 50 is in clearance fit with the outer surface of the guide rod 40, so that the force direction of the vertical vibration isolation device 10 can be limited by the guide rod 40 and the guide sleeve 50, the vertical vibration isolation device 10 is mainly subjected to axial load, and shear deformation of the vertical vibration isolation device 10 is avoided, which is beneficial to improve the bearing capacity and stability of the axial load of the vertical vibration isolation device 10. In addition, since the guide rod 40 and the guide sleeve 50 are in clearance fit, the guide rod 40 and the guide sleeve 50 have large transverse shear stiffness and can move freely in the axial direction, so that the vertical vibration isolation device 10 is almost not subjected to transverse shear load, and the vertical compression deformation and the transverse shear deformation of the friction pendulum combined three-dimensional vibration isolation support 1 are concentrated in different parts, i.e., the vertical compression deformation is concentrated in the vertical vibration isolation device 10, and the vertical mechanical properties of the friction pendulum combined three-dimensional vibration isolation support 1 are controlled by the vertical vibration isolation device 10; the horizontal shear deformation is concentrated in the friction pendulum assembly 60, and the horizontal mechanical properties of the friction pendulum combined three-dimensional vibration isolation support 1 are controlled by the friction pendulum assembly 60, so that the vertical mechanical properties and the horizontal mechanical properties of the friction pendulum combined three-dimensional vibration isolation support 1 can be designed respectively, and the designability and stability during operation of the friction pendulum combined three-dimensional vibration isolation support 1 are improved.

[0044] In addition, by arranging the stop edge 612, the sliding plate 62 can be stopped by the stop edge 612, and the sliding plate 62 is prevented from being separated from the sliding friction surface 611, so as to ensure the reliability of the friction pendulum combined three-dimensional vibration isolation support 1.

[0045] Therefore, the friction pendulum combined three-dimensional vibration isolation support 1 according to the embodiment of the present application can meet the vibration isolation requirements in the horizontal and vertical directions, and has the advantages of good vibration isolation effect and strong applicability.

In this way, the surfaces with the same curvature radius can be easily matched in sliding, the sliding range of the sliding layer 623 on the sliding friction surface 611 is larger, and the sliding between the sliding layer 623 and the sliding friction surface 611 and the sliding between the slider sliding friction surface 624 and the slider sliding layer 625 are more likely to occur, so that the structure of the friction pendulum combined three-dimensional vibration isolation support 1 is more reasonable.

[0056] More specifically, as shown in Figure 13 the curvature radius of the upper sliding friction surface 633 is equal to that of the upper sliding layer 634, and the curvature radius of the lower sliding friction surface 643 is equal to that of the lower sliding layer 644. The horizontal projection diameter of the upper sliding friction surface 633 is greater than that of the upper sliding layer 634, and the horizontal projection diameter of the lower sliding friction surface 643 is greater than that of the lower sliding layer 644. At this time, when the friction pendulum combined three-dimensional vibration isolation support 1 is subjected to a lateral load, the upper sliding layer 634 and the upper sliding friction surface 633 slide relative to each other, and the lower sliding layer 644 and the lower sliding friction surface 643 slide relative to each other, so that the friction pendulum combined three-dimensional vibration isolation support 1 can achieve a larger lateral deformation.

[0057] In some embodiments of the present application, as shown in Figures 1-6 the vertical vibration isolation device 10 includes a plurality of laminated rubber blocks 11 and a plurality of partition plates 12, and the plurality of laminated rubber blocks 11 and the plurality of partition plates 12 are alternately stacked in the up-down direction. The horizontal cross section of the laminated rubber block 11 and the partition plate 12 is circular or square and has a through hole through the guide rod 40 and the guide sleeve 50. Specifically, the partition plate 12 can be a metal plate, such as a steel plate. Under the action of vertical pressure, the laminated rubber block 11 in the vertical vibration isolation device 10 will be compressed and deformed laterally, i.e., the rubber will tend to extrude outward, and the partition plate 12 will constrain the lateral deformation of the laminated rubber block 11, so that the vertical vibration isolation device 10 has a larger vertical bearing capacity and a smaller vertical stiffness. By adjusting the thickness of the laminated rubber block 11, the size of the constraint of the rubber layer by the partition plate 12 can be changed, thereby changing the strength and stiffness of the vertical vibration isolation device 10.

[0058] In some other embodiments of the present application, as shown in Figure 7 and Figure 8 、 Figures 11-13As shown, the vertical vibration isolation device 10 comprises a coil spring 13 arranged outside the guide sleeve 50 or inside the guide rod 40. In this way, the coil spring 13 can be compressed in the vertical direction, and the coil spring 13 can be prevented from losing stability in the horizontal direction under a large vertical pressure, so that the vertical vibration isolation device 10 has a large vertical load capacity and a small vertical stiffness.

[0059] In some other embodiments of the present application, as shown in Figure 9 and Figure 10 As shown, the vertical vibration isolation device 10 comprises a plurality of disc springs 14 stacked in the vertical direction, and the disc springs 14 are arranged outside the guide sleeve 50. In this way, the disc springs 14 can be compressed in the vertical direction, and the disc springs 14 can be always ensured to be axially aligned, so that the vertical vibration isolation device 10 has a large vertical load capacity and a small vertical stiffness.

[0060] In some other embodiments of the present application, as shown in Figure 11 As shown, the friction pendulum combined three-dimensional vibration isolation support 1 further comprises an inner guide rod 70 arranged inside the guide rod 40, and the vertical vibration isolation device 10 comprises a coil spring 13 arranged inside the guide rod 40 and outside the inner guide rod 70. In this way, the coil spring 13 can be compressed in the vertical direction, and the coil spring 13 can be prevented from losing stability in the horizontal direction under a large vertical pressure, so that the vertical vibration isolation device 10 has a large vertical load capacity and a small vertical stiffness.

[0061] Advantageously, as shown in the vertical vibration isolation device 10 is a plurality of and arranged in the horizontal direction. The guide rod 40 and the guide sleeve 50 are a plurality of and the plurality of guide rods 40 are correspondingly matched in the plurality of guide sleeves 50, the vertical vibration isolation device 10 comprises a plurality of disc springs 14 stacked in the vertical direction and a plurality of vertical vibration isolation devices 10 correspondingly arranged outside the plurality of guide sleeves 50, or the vertical vibration isolation device 10 comprises a coil spring 13 and is correspondingly arranged outside the plurality of guide sleeves 50 or inside the guide rod 40. In this way, the plurality of vertical vibration isolation devices 10 can be used to support the first connecting plate 20 and the second connecting plate 30, improve the force uniformity and stability of the friction pendulum combined three-dimensional vibration isolation support 1, further improve the vertical load capacity of the friction pendulum combined three-dimensional vibration isolation support 1, and improve the vertical vibration isolation effect of the friction pendulum combined three-dimensional vibration isolation support 1.
