AI Technical Summary
Existing friction pendulum seismic isolation bearings, when the friction coefficient is low, will cause displacement when high-rise buildings are subjected to large wind loads, affecting the swaying of items inside the building and comfort. However, increasing the friction coefficient may prevent the displacement from being released during an earthquake, increasing the damage to the building caused by the earthquake.
A wind-resistant pin is installed between the support plates, including a shear groove in the middle of the pin and fixed by a top screw and a locking groove. Combined with the cooperation of stainless steel sliding plate and polymer material sliding plate, a dustproof ring is added to improve wind resistance.
Under strong wind loads, the bearing plates do not move relative to each other, reducing the swaying of objects and improving comfort; during earthquakes, the shear groove breaks and releases displacement, reducing earthquake damage, and the wind-resistant structure is stable and reliable with good seismic isolation effect.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of friction pendulum seismic isolation support, especially to a friction pendulum seismic isolation support with wind resistance function. BACKGROUND
[0002] The friction pendulum seismic isolation support is a new type of seismic isolation device, which is mainly used for improving the seismic performance of building structures. The support utilizes the sliding between two curved surfaces and their respective corresponding concave spherical surfaces to form a pendulum mechanism. During an earthquake, the seismic energy is consumed through the friction between the sliding surface and the concave spherical surface, and the horizontal seismic response is reduced by utilizing the conversion of kinetic energy and potential energy when the overall structure is lifted. The basic components of the friction pendulum support include anchoring devices, upper support plates, upper sliding friction surfaces, spherical crown bodies, lower sliding friction surfaces, lower support plates, and other parts.
[0003] However, in the prior art, when the friction coefficient of the friction pendulum seismic isolation support is low, the high-rise building will displace under the action of a large wind load, which will affect the shaking of the objects inside the building or the comfort of the people inside the building. If the friction coefficient of the friction pendulum seismic isolation support is increased, the problem of the building shaking under the action of the wind load can be solved, but the friction pendulum seismic isolation support may not be able to release displacement during a low-magnitude earthquake, which will amplify the destructive effect of the earthquake on the building.
[0004] Therefore, it is necessary to develop a friction pendulum seismic isolation support with wind resistance function to solve the above-mentioned defects. SUMMARY
[0005] The utility model aims at providing a friction pendulum seismic isolation support with wind resistance function, which improves the wind resistance performance of the friction pendulum seismic isolation support by setting a wind resistance pin shaft between the support plates.

The dustproof ring is hermetically sealed in the annular gap between the two support plates. The wind resistance pin shaft is vertically inserted between the upper and lower support plates, and a shear groove is arranged in the middle of the wind resistance pin shaft.
[0008] Further, the number of wind resistance pin shafts is two or more, and the wind resistance pin shafts are circumferentially distributed at the outer edges of the support plates.
[0009] Further, the anti-wind pin shaft is provided with a locking groove at both ends, and the outer wall of the support plate is provided with a locking hole at the insertion groove of the anti-wind pin shaft; the locking hole is screwed with the jack screw, and the inner end of the jack screw abuts in the locking groove.

[0030] In one specific implementation, such as Figures 1 to 6 As shown, the friction pendulum vibration isolation bearing with wind resistance of this utility model includes a support plate 1, a spherical crown 4, a polymer material sliding plate 5, and a dustproof ring 9. Polymer material sliding plates 5 are respectively and conformally arranged on the upper and lower spherical crown surfaces of the spherical crown 4, and the two polymer material sliding plates 5 respectively contact the concave spherical surfaces of the upper and lower support plates 1. Specifically, the polymer material sliding plates 5 are made of polytetrafluoroethylene or polyketone polymer material with good wear resistance. Four lugs 101 are evenly distributed around the circumference of the end of the support plate 1 away from the spherical crown 4, and through holes for installing pre-embedded bolts are opened on the lugs 101. The dustproof ring 9 is sealed in the annular gap between the two support plates 1. A key innovation of this application compared to existing friction pendulum vibration isolation bearings is that it also includes a wind-resistant pin 7, which is vertically inserted between the upper and lower support plates 1, and a shear groove 702 is provided in the middle of the wind-resistant pin 7.
[0031] Specifically, such as Figure 6 As shown, the shear groove 702 is an annular groove, and the bottom surface of the annular groove is an arc-shaped surface. The wind-resistant pin 7 is made of ordinary carbon steel. In fact, the bottom diameter of the shear groove 702 and the outer diameter of the wind-resistant pin 7 are designed after optimization simulation based on specific load conditions, building height, and wind load conditions. It is required that no breakage will occur under the design wind load, but that the shear groove 702 will break under the increased load during an earthquake without affecting the seismic isolation effect.
[0032] The two support plates 1 will not move relatively under the condition of large wind load by adding the wind resisting pin shaft 7 between the two support plates 1, the support rigidity is better, the shaking of articles in the building is reduced, and the comfort of people in the building is improved; the wind resisting pin shaft 7 is sheared at the shearing groove 702 in the middle of the wind resisting pin shaft 7 under the action of strong earthquake energy when the earthquake occurs, the relative displacement of the support is released, and the earthquake damage is reduced. The friction pendulum seismic isolation support with the wind resisting function has the wind resisting performance of the friction pendulum seismic isolation support improved by arranging the wind resisting pin shaft between the support plates.
[0033] In a specific embodiment of the utility model, as shown in Figure 2 and Figure 3 The number of wind resisting pin shafts 7 is two or more, and the two or more wind resisting pin shafts 7 are circumferentially distributed on the inward plane of the outer edge of the support plate 1.
[0034] By arranging the multiple wind resisting pin shafts 7, uniform shearing resistance can be formed on the entire outer circumference of the support plate 1, and the wind resisting structure is more stable and reliable.
[0035] In a specific embodiment of the utility model, as shown in Figures 1 to 4 and Figure 6 The friction pendulum seismic isolation support with the wind resisting function also comprises a jackscrew 8, both ends of the wind resisting pin shaft 7 are provided with a locking groove 701, and the outer wall of the support plate 1 is provided with a locking hole 102 at the insertion groove of the wind resisting pin shaft 7. The locking hole 102 is a threaded hole and is perpendicular to the insertion groove of the support plate 1. The jackscrew 8 is threadedly connected to the locking hole 102, and the inner end of the jackscrew 8 abuts in the locking groove 701.
[0036] Specifically, as shown in Figure 6 The locking groove 701 is also an annular groove, facilitating the abutment of the inner end of the jackscrew 8, and the wind resisting pin shaft 7 can be locked after being installed at any angle.
[0037] By additionally arranging the jackscrew 8 and the locking groove 701, the wind resisting pin shaft 7 can be locked in the insertion groove of the support plate 1, preventing the wind resisting pin shaft 7 from falling off and sliding out after deformation.
[0038] In a specific embodiment of the utility model, as shown in Figures 2 to 4 and Figure 5 The friction pendulum seismic isolation support with the wind resisting function also comprises a stainless steel sliding plate 2, the stainless steel sliding plate 2 is laid on the concave spherical surface of the support plate 1, and the high polymer material sliding plate 5 is in sliding contact with the stainless steel sliding plate 2.
[0039] Specifically, as shown in Figure 4 The support plate 1 is circumferentially and uniformly provided with multiple screws one 3 at the top edge of the concave spherical surface, and the screw cap of the screw one 3 presses the edge of the stainless steel sliding plate 2.
[0040] Specifically, as shown inFigure 5 As shown in the drawings, the high polymer material sliding plate 5 is installed on the upper and lower spherical crown surfaces of the spherical crown body 4 by means of adhesive or by means of the countersunk screw 6.
[0041] The close sliding fit of the stainless steel sliding plate 2 and the high polymer material sliding plate 5 can reduce the friction coefficient, and the relative displacement is easy to occur during an earthquake, and the seismic isolation effect is good.
[0042] In a specific embodiment of the present application, as shown in Figure 3 and Figure 4 As shown in the drawings, the dustproof ring 9 is made of extrusion molding of EPDM rubber, and the cross section is a convex ring table with a middle hole and clamped on the inner side of the support plate 1 by means of the upper and lower clamping grooves.
[0043] The dustproof ring 9 made of extrusion molding of EPDM rubber has high weather resistance, and can reduce the influence of the external environment. The cross section structure with a middle hole can also have a certain degree of heat insulation function, and reduce the influence of the external temperature on the inner high polymer material sliding plate 5.
[0044] The working principle of the friction pendulum seismic isolation support with wind resistance function is as follows: when the building provided with the friction pendulum seismic isolation support with wind resistance function bears wind load, the two support plates 1 of the present application will not be displaced due to the limiting effect of the wind resistance pin shaft 7, thereby reducing the shaking of the articles in the building and improving the comfort of the people in the building. When an earthquake occurs, the wind resistance pin shaft 7 is sheared along the middle shear groove 702, the friction pendulum seismic isolation support with wind resistance function releases displacement, and the seismic energy is consumed by the friction between the stainless steel sliding plate 2 and the high polymer material sliding plate 5. At the same time, the horizontal seismic response of the building structure is reduced by the conversion of kinetic energy and potential energy when the building structure is lifted as a whole, and the effect of isolating the earthquake is good.
