The adjustment process of the friction pendulum support that present embodiment provides is as follows:
Under the effect of the horizontal lateral force that is caused by earthquake etc., seat structure above the lower slider plate 9 of friction pendulum support carries out slippage with integral body along the guiding direction of the first guide-track groove 100 and the second guide-track groove 110, when being subjected to displacement, the friction pendulum support of lower slider plate 9 tops slides along the first guide-track groove 100, and be elevated, simultaneously the top bridge of friction pendulum support or the structure of building are elevated in sliding process, thereby the power conversion that will act on friction pendulum support by seimic horizontal lateral force is the gravitional force of friction pendulum support, simultaneously, the frictional resistance of bearing self carries out damping consumption to the energy that earthquake produces again.The staggered form design of the first guide rail 101 and the second guide rail 111, so that the seat structure above the lower slider plate 9 moves the guiding direction of integral body along the first guide-track groove 100 and the second guide-track groove 110, when only moving along the first guide rail 101 or the second guide rail 111 directions, friction pendulum support can only be realized the slippage of single direction, but when moving along two guide rail directions simultaneously, then can fit to level by the sliding displacement of both direction to omnibearing sliding displacement.And the displacement that the maximum displacement that fits to provides greater than any single guide rail direction, by the slip length of two guide rail directions of rational design, and the reasonable Arrangement bearing, can take full advantage of the shift length that fits to and subtract shock insulation.

The first guide rail 101 and 100 actings in conjunction of the first guide-track groove, be subject to the horizontal lateral force that earthquake etc. causes at friction pendulum support and do the time spent, part above the friction pendulum support is carried out slippage along the guiding direction of the first guide rail 101, and the first guide rail 101 is arranged on the medium position of the first convex cylinder on the spherical crown board 2.Preferably, the second guide rail 111 is arranged on the medium position of the second convex cylinder at spherical crown liner plate 5 tops, same, utilize the second guide rail 111 and the guiding and the supporting role that are arranged on 110 pairs of friction pendulum supports of the second guide-track groove on the upper sliding plate 1, realize that friction pendulum support edge when being subject to horizontal lateral force is subjected to force direction to carry out position adjustments.
In order further to optimize technique scheme, in the friction pendulum support that present embodiment provides, the first guide rail 101 is mutually vertical with second projection of the second guide rail 111 on horizontal plane in the first projection on the horizontal plane.The first guide rail 101 and the second guide rail 111 adopt orthogonal set-up mode, because the first guide rail 101 and the second guide rail 111 are respectively along the glide direction of lower slider plate 9 and upper sliding plate 1, then in friction pendulum support, upper sliding plate 1 is mutually vertical with lower slider plate 9, be criss-cross construction, so that friction pendulum support is when being subject to the horizontal lateral force of any direction, all can horizontal lateral force be decomposed into component along horizontal and vertical both direction by cross one another structure, in the slipping of friction pendulum support, realize its slippage along two glide directions, the sliding displacement of both direction is fitted to level to omnibearing sliding displacement, improve the omnibearing shock resistance that friction pendulum supports, and horizontal lateral force has been converted to the potential energy of friction pendulum support by the lifting of friction pendulum superstructure.
The friction pendulum support that present embodiment provides; it is in the time spent of doing that is subject to horizontal lateral force; its superstructure produces slippage along the friction guiding direction of the first spill cylinder of lower slider plate 9; and utilize the characteristics of spill cylinder; the superstructure of friction plate bearing can be done in the structure of spill cylinder and be similar to pendular movement; therefore; can prolong by designing the different rubbing surface cycles natural vibration period of friction pendulum support; reduced by seimic power augmentation effect; and the friction of rubbing surface is carried out effective damping to seismic energy, reaches the purpose of protection pier and superstructure.And after earthquake, friction pendulum support under action of gravitation, return back to the spill cylinder minimum point (near), avoided the adjustment operation after the shake, realized auto restore facility after the friction pendulum support shake.
Friction pendulum support is being subject to doing the time spent such as seimic horizontal external, relative slippage occurs between the each several part structure of friction pendulum support, consider that friction pendulum support is generally used for the bottom of bridge or building etc., be subject to the effect of the external force of great vertical direction, therefore it is subject to the effect of great frictional force, the wearing and tearing that easily produce the friction pendulum support structure in the slippage engineering.In order to improve the application life of friction pendulum support, reduce the wearing and tearing between the each several part structure in the friction pendulum support slipping, all be pasted with corrosion resistant plate on the convex spherical of the first spill cylinder of lower slider plate 9, the second spill cylinder on the upper sliding plate 1 and arena liner plate 5 and (be provided with cylinder corrosion resistant plate 15 on the first spill cylinder, be provided with cylinder corrosion resistant plate 151 on the second spill cylinder, be pasted with sphere corrosion resistant plate 4 on the convex spherical).Corrosion resistant plate is attached on the contact plane of each several part structure of bearing, it has increased the friction resistant ability of friction pendulum support, has avoided the wearing and tearing of friction pendulum support.Concrete, each corrosion resistant plate is connected on the second above-mentioned spill cylinder, the first spill cylinder and the convex spherical by the mode of welding, so that have firm switching performance between the each several part structure of friction pendulum support and the corrosion resistant plate, further guaranteed the stability of friction pendulum support.
In order further to guarantee the steadiness of friction pendulum support sliding friction, attach corrosion resistant plate at the first spill cylinder of upper sliding plate and the second spill cylinder welding of lower slider plate, after welding attaches corrosion resistant plate on the convex spherical of spherical crown liner plate 5, the first convex cylinder of spherical crown board 2, all inlay the wearing plate (wearing plate 14 on the first convex cylinder on the second convex cylinder of spherical crown liner plate 5 and the spill sphere of spherical crown board 2, wearing plate 141 on the second convex cylinder and the wearing plate 3 on the spill sphere), wearing plate has very high anti-wear performance and impact property preferably, it cooperates the formation sliding friction pair with corrosion resistant plate, guaranteed that friction pendulum support absorbs rotation and the displacement of the structure generation on friction pendulum support top in sliding process, and can be in sliding process consume a part by damping and act on energy on the friction pendulum support by horizontal lateral force, further improved the anti-seismic performance of friction pendulum support.
Particularly, wearing plate 14 and wearing plate 141 are cylinder heat resistant type wearing plate, and wearing plate 3 is the sphere wearing plate.Wearing plate is installed on each installed surface by the mode of mosaic bonding.
Relatively rotate between the spill sphere of spherical crown board 2 and the convex spherical of spherical crown liner plate 5, attach corrosion resistant plate 4 by inlaying respectively wearing plate 3 and welding between the two, the formation pivoting friction is secondary, reaching between the two in the rotating function, has avoided the seat wear that produces between the two.
Certainly, the arrangement method of the above-mentioned corrosion resistant plate that provides and wearing plate is provided present embodiment, and when alleviating wearing and tearing and have the good friction performance between each structure that guarantees friction pendulum support, corrosion resistant plate and wearing plate can also have multiple distribution mode.
In order further to optimize technique scheme, in the friction pendulum support that present embodiment provides, all be pasted with SF-1 wear rib (the first wear rib 10 on the first guide rail 101 and the second wear rib 11 on the second guide rail 111) on the first guide rail 101 and the second guide rail 111, all be pasted with stainless steel strip (the second stainless steel strip 13 on the first guide-track groove 100 on the first stainless steel strip 12 and the second guide-track groove 110) on the cell wall of the first guide-track groove 100 and the second guide-track groove 110.The first guide rail 101 and the first guide-track groove 100 and the second guide rail 111 and the second guide-track groove 110 need to lead to its slippage when friction pendulum support produces slippage on the one hand, rely on the other hand the frictional resistance that produces between the two to eliminate the energy that a part of earthquake produces.By increasing the method for wear rib and stainless steel strip, so that form sliding friction pair between guide rail and the guide-track groove, improved the buffer capacity of friction pendulum support under earthquake conditions.Wear rib adopts the wear rib of SF-1, and it is applicable to refuel or very difficult place of refueling, and can not maintain in use or few maintenance; Anti-wear performance is good simultaneously, and friction factor is little, long service life.
Concrete, the stainless steel strip on the first guide-track groove 100 and the second guide-track groove 110 all is attached on the friction pendulum support by the mode of welding.
Friction pendulum support is in the time spent of doing that is subject to such as the horizontal lateral force of the generations such as earthquake, the structure on lower slider plate 9 tops of friction pendulum support is carried out slippage along the guiding direction of the first guide rail 101, position in slipping on the first spill cylinder raises gradually, the active force of horizontal lateral force is converted to the gravitional force of a part of bridge or building etc. at this moment, thus the impact that has alleviated horizontal lateral force.Because the unicity of the guiding direction of guide rail, inevitably, friction pendulum support can be subject to the effect of rotating torque, at this moment, owing to be that pivoting friction is secondary between spherical crown liner plate 5 and the spherical crown board 2, friction pendulum support passes through the up and down mutual rotation of two-part structure and offsets rotating torque to the active force of friction pendulum support, has further guaranteed the anti-seismic performance of friction pendulum support.
For the stabilized structure of the bearing that guarantees to rub, spherical crown board 2 is respectively arranged with the first positive stop 6, the second positive stop 61, the 3rd positive stop 62 and the 4th positive stop along the both sides of upper sliding plate 1 width and the both sides of lower slider plate 9 width.The two ends of the first positive stop 6 and the second positive stop 61 are provided with the upper limit position block that restriction upper sliding plate 1 slides along its length direction; The two ends of the 3rd positive stop 62 and the 4th positive stop are provided with the described spherical crown board 2 of restriction along the lower position block of the length direction slip of described lower slider plate 9.
Friction pendulum support is subject to time spent of doing of larger horizontal lateral force at states such as earthquakes, can cushion and guarantee the stable of its structure to the active force of outside by the structure of himself.In the stress condition of at ordinary times normal use, the steady status that still needs it to keep relative stability.Increase by the first positive stop 6, the second positive stop 61, the 3rd positive stop 62 and the 4th positive stop, and the upper limit position block that restriction upper sliding plate 1 slides along its length direction is set all at the two ends of the first positive stop 6 and the second positive stop 61, restriction spherical crown board 2 is set along the lower position block of the length direction slip of lower slider plate 9 at the two ends of the 3rd positive stop 62 and the 4th positive stop, so that friction pendulum support is in the time spent of doing that is subject to external force, at first rely on the structure of self that applied external force is offseted, when external force surpasses the carrying limit value of its fixed structure, further offset again the effect of external force by the sliding tray structure, thereby guaranteed the stability of whole friction pendulum support.
Simultaneously, arrange on the friction pendulum support spacing limited block is carried out in its slip along the length direction of upper sliding plate and lower slider plate, between the positive stop of the same side positive stop is set, by stopping means (active type without) is set, so that friction pendulum support need not to arrange the limiting plate that extends to bearing bearing structure center from sliding panel sliding displacement distal-most end, and can be directly to bearing center bearing structure (the spherical crown liner plate in the present embodiment, spherical crown board and wearing plate etc.) stopping means formation one-way type and fixed bearing are set, take up room thereby reduce a seat body.
After the utility model design horizontal force that bearing is subject to when earthquake reaches design shear, what cut off is respectively limited block, the set bolt that has sufficient intensity by employing, can effectively avoid the unbalance stress that adopts a plurality of shearing pins (or similar structures) to cause easily when horizontal shear is provided, thereby cut off one by one the situation that final shearing pin (or similar structures) all lost efficacy.Simultaneously, after the earthquake, the utility model can simply be unscrewed the hold-down screw on capping position piece or the lower position block, only changes limited block and gets final product, and has avoided adopting a plurality of position-limitting pins (or similar structures) to be not easy to take off pin (or similar structures) and the not easily changeable problem of being cut off.
Concrete, upper limit position block is fixedly installed on the upper sliding plate 1 by shearing bolt.Lower position block is fixedly installed on the lower slider plate 9 by shearing bolt.
As shown in Figure 4, the top view of friction pendulum support when normal operating conditions that provide for present embodiment of Fig. 4.
When friction pendulum support is under the normal duty, this moment, upper sliding plate 41 and lower slider plate 49 projected into criss-cross construction on the same level face.All can be offset between spherical crown board and the lower slider plate 49 and between upper sliding plate 41 and the spherical crown board, upper sliding plate 41 is fixed by the first blocking of positive stop 46 by the first upper limit position block 48 and the second upper limit position block 481 disposed thereon.The two ends symmetry of the width of upper sliding plate 41 two pairs of limited blocks and a pair of positive stop be set, upper sliding plate is when sliding, four upper limit position blocks of its periphery are stopped its slip by the first positive stop 46 and the second positive stop 461 respectively, thereby have avoided upper sliding plate 41 to produce slip when external force.In like manner, lower slider plate 49 is by being arranged on four lower position blocks of its width periphery, block with the 3rd positive stop and the 4th positive stop, the two ends symmetry of the width of lower slider plate 49 a pair of positive stop and two pairs of limited blocks are set, blocking when it realizes the structure slippage of lower slider plate 49 tops jointly, thereby avoided producing relative sliding between spherical crown board and the lower slider plate 49, guaranteed the stability of structure.
As shown in Figure 5, friction pendulum support structural representation after being subject to horizontal lateral force of providing for present embodiment of Fig. 5.
Friction pendulum support is done the time spent being subject to horizontal lateral force, and when the active force less of horizontal lateral force, friction pendulum support at first carries out partial offset to applied external force by upper limit position block, lower position block and each positive stop.When the horizontal lateral force of outside surpasses the utmost carrying ability of limited block and positive stop, upper limit position block and limited block are cut off, the spherical crown board produces slippage at lower slider plate 59, because lower slider plate 59 has the spill spherical structure, therefore friction pendulum support is in the minimum point of spill sphere when normal condition, during the instantly structure generation slippage of sliding panel 59 tops, it slides to the higher position of spill sphere along lower slider plate 59 spill sphere upper rail grooves, absorb the energy of a part of horizontal lateral force by the variation of its position height, and finally consume by frictional damping, thereby guaranteed the stability of friction pendulum support and superstructure.
When upper sliding plate 51 changes in the position of friction pendulum support, also slide with the displacement of friction pendulum support in its carrying position, thereby the horizontal lateral force that realizes upper sliding plate 51 and 59 pairs of all directions of lower slider plate is decomposed into the both direction along the two, has stronger shock resistance.Concrete, upper sliding plate 51 and lower slider plate 59 all are set to radian length greater than the arc length of spherical crown board and spherical crown liner plate, then when spherical crown board during in the enterprising line slip of lower slider plate, the lower slider plate can provide long guiding distance, has further improved shock resistance.When upper sliding plate and spherical crown liner plate generation relative sliding, upper sliding plate provides the spherical crown liner plate long skidding distance, and is same, increased the shock resistance of friction pendulum support.
