Description

Technical Field

[0001] The present invention relates to the technical field of vibration reduction and isolation, and in particular to a friction pendulum combined three-dimensional vibration reduction and isolation bearing using vertically laminated rubber. Background Art

[0002] Earthquake disasters often cause significant casualties and economic losses, primarily due to structural damage and equipment damage. The development of structural seismic resistance technology is of great significance, effectively reducing losses caused by earthquakes and protecting people's lives and property. In addition to relying on the inherent performance of structures to resist earthquakes, seismic isolation devices, such as energy-absorbing braces and isolation bearings, can also be used to mitigate earthquake damage.

[0003] Currently, the most widely used isolation bearings are mainly laminated rubber bearings and friction pendulum bearings. There is no doubt that practice has proved that both types of bearings have good isolation effects on horizontal earthquakes. However, due to the structural limitations of the bearings, laminated rubber bearings and friction pendulum bearings cannot effectively isolate vertical vibrations. Therefore, in some cases, the above two types of bearings cannot meet the requirements of the structure or equipment for vertical isolation and may even amplify vertical vibrations. The use of combined bearings can achieve three-dimensional isolation, but attention should be paid to strengthening the correlation between the components of the combined bearings and controlling the height of the bearings. If it is simply superimposed and combined, it may cause the bearings to be too high and the connections between the components to be loose, and it is impossible to achieve a good three-dimensional isolation effect. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention can achieve horizontal and vertical dual vibration isolation by arranging a vertical laminated rubber vibration isolation device and a horizontal friction pendulum vibration isolation device on the base. The friction pendulum is placed in the vertical laminated rubber vibration isolation device, and the vertical laminated rubber is used to provide the friction pendulum with pull-out resistance. The force is reasonable, the total height is low, the stability is high, and the components are tightly connected, with good pull-out resistance. The vertical bearing capacity range is large, and the overlapping height, thickness and number of layers of the high-damping rubber layer can be adjusted according to the bearing requirements.

[0017] 2. The vertical laminated rubber seismic isolation device of the present invention includes an upper seat plate, a high-damping rubber layer and a lower seat plate of the vertical seismic isolation device.

The upper connecting tooth and the lower connecting tooth are both annular, and the upper connecting tooth and the lower connecting tooth are arranged in an opposite direction. The upper connecting tooth and the lower connecting tooth are bonded and filled with a high-damping rubber layer. When the structure is subjected to a vertical earthquake, the upper seat plate and the lower seat plate of the vertical seismic isolation device undergo vertical relative movement, causing the high-damping rubber layer between the upper connecting tooth and the lower connecting tooth to undergo shear deformation, thereby achieving the effect of consuming and isolating vertical seismic energy.

The connecting teeth of the upper tooth plate of the spherical crown and the connecting teeth of the lower tooth plate of the spherical crown are arranged oppositely and alternately, and the middle rubber layer of the spherical crown is used to paste and fill the gaps between the connecting teeth. When the structure is subjected to an earthquake, the relative sliding of the various components of the horizontal friction pendulum seismic isolation device and the up and down movement of the upper seat plate will cause the connecting teeth of the upper tooth plate of the spherical crown and the connecting teeth of the lower tooth plate of the spherical crown to be dislocated, and the middle rubber layer will also be deformed, thereby consuming the earthquake energy.

DETAILED DESCRIPTION

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1

[0039] See Figures 1-13 A three-dimensional seismic isolation bearing with a friction pendulum combination of vertically laminated rubber includes a base 1, a vertically laminated rubber seismic isolation device and a horizontal friction pendulum seismic isolation device. The base 1 is fixed to the equipment foundation or structure foundation by bolts, and the base 1 is provided with a vertically laminated rubber seismic isolation device and a horizontal friction pendulum seismic isolation device.

[0040] It can achieve dual horizontal and vertical seismic isolation. The friction pendulum is placed in a vertical laminated rubber seismic isolation device, and the vertical laminated rubber is used to provide pull-out resistance for the friction pendulum. It has reasonable force, low total height, high stability, and tight connections between various components. It has good pull-out resistance and a wide range of vertical bearing capacity. The overlapping height, thickness and number of layers of the high-damping rubber layer can be adjusted according to the bearing requirements.

[0041] The vertical laminated rubber seismic isolation device includes an upper seat plate 14, a high-damping rubber layer 10 and a lower seat plate 3 of the vertical seismic isolation device. The lower surface of the upper seat plate 14 is provided with an upper connecting tooth 141, and the upper surface of the lower seat plate 3 of the vertical seismic isolation device is provided with a lower connecting tooth 31. The upper connecting tooth 141 and the lower connecting tooth 31 are both annular, and the upper connecting tooth 141 and the lower connecting tooth 31 are arranged in an staggered and opposite manner. The high-damping rubber layer 10 is used to bond and fill the upper connecting tooth 141 and the lower connecting tooth 31.

[0042] It should be noted that when the structure is subjected to vertical earthquake action, the upper seat plate 14 and the lower seat plate 3 of the vertical seismic isolation device undergo vertical relative movement, causing the high-damping rubber layer 10 between the upper connecting teeth 141 and the lower connecting teeth 31 to undergo shear deformation, thereby achieving the effect of consuming and isolating vertical seismic energy.

[0043] The number of rings of the upper engaging teeth 141 and the lower engaging teeth 31 is determined according to actual structural requirements. The inclination angles of the side walls of the upper engaging teeth 141 and the lower engaging teeth 31 are both 90°-120°.

[0044] The thickness, overlap height and number of layers of the high damping rubber layer 10 are determined according to the load-bearing requirements of the actual structure.

[0045] The horizontal friction pendulum seismic isolation device includes an upper seat plate 14, an upper sliding friction surface 15 of the friction pendulum, an upper sliding layer 13 of the friction pendulum, a spherical crown 11, a lower sliding friction surface 12 of the friction pendulum, a lower sliding layer 9 of the friction pendulum, a lower seat plate 6 of the friction pendulum, a lower seat plate sliding layer 7 and a sliding friction surface 5.

[0046] It should be noted that the horizontal friction pendulum isolation device is entirely located between the upper base plate 14 and the lower base plate 3 of the vertical vibration isolation device, and the vertical laminated rubber vibration isolation device provides the horizontal friction pendulum isolation device with anti-pullout capability.

[0047] The bottom spherical surface of the upper seat plate 14 is covered with a stainless steel plate to form the friction pendulum upper sliding friction surface 15, the friction pendulum upper sliding layer 13 is pasted into the groove on the upper surface of the spherical crown 11, and the friction pendulum upper sliding layer 13 is tightly attached to the friction pendulum upper sliding friction surface 15, the friction pendulum upper sliding friction surface 15 and the friction pendulum upper sliding friction layer 13 constitute a friction pendulum upper sliding friction pair, the lower surface of the spherical crown 11 is covered with a stainless steel plate to form a friction pendulum lower sliding friction surface 12, the friction pendulum lower sliding layer 9 is pasted into the upper surface groove of the friction pendulum lower seat plate 6, and the friction pendulum lower sliding layer 9 is tightly attached to the bottom of the friction pendulum lower sliding friction surface 12, the friction pendulum lower sliding friction surface 12 and the friction pendulum lower sliding layer 9 constitute a friction pendulum lower sliding friction pair.

[0048] The upper surface of the lower seat plate 3 of the vertical seismic isolation device is covered with a stainless steel plate to form a sliding friction surface 5. The friction pendulum lower seat plate sliding layer 7 is pasted into the groove at the bottom of the friction pendulum lower seat plate 6 and placed on the lower seat plate 3 of the vertical seismic isolation device, and is close to the sliding friction surface 5. The sliding friction surface 5 and the friction pendulum lower seat plate sliding layer 7 constitute a friction pendulum lower seat plate sliding friction pair, so that the friction pendulum lower seat plate 6 can slide on the lower seat plate 3 of the vertical seismic isolation device, so the entire horizontal friction pendulum seismic isolation device can still be used normally inside the vertical laminated rubber seismic isolation device.

[0049] The vertical seismic isolation device lower seat plate sliding layer 4 is pasted in the groove on the bottom surface of the vertical seismic isolation device lower seat plate 3, and the upper surface of the base 1 is covered with a stainless steel plate to form a base sliding friction surface 2. The base sliding friction surface 2 is placed under the vertical seismic isolation device lower seat plate sliding layer 4. The base sliding friction surface 2 is tightly attached to the vertical seismic isolation device lower seat plate sliding layer 4 to form a sliding friction pair on the base. The central protrusion of the base 1 passes through the base sliding friction surface 2, the vertical seismic isolation device lower seat plate sliding layer 4, the vertical seismic isolation device lower seat plate 3, the sliding friction surface 5 and the friction pendulum lower seat plate sliding layer 7 in sequence, and the central protrusion of the base 1 is embedded in the friction pendulum lower seat plate 6, and the central protrusion of the base 1 is connected and fixed to the friction pendulum lower seat plate 6 by a fastening bolt 8.

[0050] Four fastening bolts 8 are used to connect and fix the central protrusion of the base 1 to the friction pendulum lower seat plate 6, so that the horizontal friction pendulum seismic isolation device and the vertical laminated rubber seismic isolation device can be fixed on the base 1.

[0051] Holes are provided on the base sliding friction surface 2, the sliding layer 4 of the lower seat plate of the vertical seismic isolation device, the lower seat plate 3 of the vertical seismic isolation device, the sliding friction surface 5 and the sliding layer 7 of the lower seat plate of the friction pendulum, so that the central protrusion of the base 1 can pass through the hole and be fixed to the lower seat plate 6 of the friction pendulum, and the size of the hole should be considered according to the displacement requirements of the structure.

[0052] It should be noted that in order not to affect the relative sliding between the lower seat plate 6 of the friction pendulum and the lower seat plate 3 of the vertical seismic isolation device, a vertical seismic isolation device lower seat plate sliding layer 4 is embedded in the lower surface of the vertical seismic isolation device lower seat plate 3, and a stainless steel plate is covered on the upper surface of the base 1 to form a base sliding friction surface 2, so that the vertical seismic isolation device lower seat plate sliding layer 4 and the base sliding friction surface 2 form a sliding friction pair on the base, so that the base 1 and the friction pendulum lower seat plate 6 can slide together relative to the vertical seismic isolation device lower seat plate 3.

[0053] The covering area of the square bottom plate of the friction pendulum lower seat plate 6 is larger than the area of the hole of the vertical seismic isolation device lower seat plate 3, and the outer area of the sliding layer 7 of the friction pendulum lower seat plate is larger than the area of the hole of the vertical seismic isolation device lower seat plate 3, so that the horizontal sliding of the vertical seismic isolation device lower seat plate 3 can be limited between the lower surface of the friction pendulum lower seat plate 6 and the upper surface of the base 1.

[0054] When the structure is subjected to an earthquake, the upper connecting teeth 141 of the upper seat plate 14 and the lower connecting teeth 31 of the lower seat plate 3 of the vertical seismic isolation device are displaced, and the high-damping rubber layer 10 between the upper connecting teeth 141 and the lower connecting teeth 31 is deformed accordingly. The upper seat plate 14, the spherical crown 11 and the friction pendulum lower seat plate 6 of the horizontal friction pendulum seismic isolation device slide relative to each other, thereby consuming and isolating the seismic energy.

[0055] Example 2

[0056] The difference from Example 1 is that:

[0057] See Figure 14-16 The spherical crown 11 of the horizontal friction pendulum seismic isolation device is composed of an upper tooth plate 161 of the spherical crown, a middle rubber layer 162 of the spherical crown, and a lower tooth plate 163 of the spherical crown. The connecting teeth of the upper tooth plate 161 of the spherical crown and the connecting teeth of the lower tooth plate 163 of the spherical crown are arranged oppositely and alternately, and the middle rubber layer 162 of the spherical crown is used to glue and fill the space between the connecting teeth.

[0058] The inclination angle of the tooth side wall of the tooth plate 161 on the spherical crown is 90 ° -120 ° The inclination angle of the tooth side wall of the ball crown lower tooth plate 163 is 90 ° -120 ° .

[0059] The thickness, overlapping height and number of rubber layers of each ring of the rubber layer 162 in the middle of the spherical crown can be determined according to the load-bearing requirements of the actual structure.

[0060] When the structure is subjected to an earthquake, the relative sliding of the various components of the horizontal friction pendulum seismic isolation device and the up and down movement of the upper seat plate 14 will cause the connecting teeth of the upper tooth plate 161 of the spherical crown body and the connecting teeth of the lower tooth plate 163 of the spherical crown body to shift, and the middle rubber layer will also deform, thereby consuming the seismic energy.

[0061] In summary, the present invention adopts a three-dimensional seismic isolation bearing combined with a friction pendulum of vertically laminated rubber. The shear deformation of the laminated rubber is used for seismic isolation in the vertical direction, and the friction pendulum is used for seismic isolation in the horizontal direction. The vertical laminated rubber bearing and the friction pendulum bearing are rationally combined. While achieving three-dimensional seismic isolation, the height of the bearing is effectively controlled, so that the bearing has good stability and pull-out resistance. Through the deformation of the high-damping rubber layer 10 and the friction of the sliding friction pair, the seismic energy can be effectively consumed and isolated, and the seismic effect borne by the structure is reduced, thereby enhancing the seismic resistance of the structure or equipment, reducing earthquake losses, and achieving the purpose of protecting the structure and equipment.

[0062] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
