In the present invention, the upper and lower end face of biconvex curved surface core 2 is convex spherical；In a preferred embodiment,
The radian of 2 upper surface of biconvex curved surface core is greater than the radian of its lower end surface, and the radian of lower end surface is more gentle.
Further, the upper surface of unidirectional damping plate 5 is the concave spherical surface adaptable with the lower end surface of biconvex curved surface core 2.
Further, the upper and lower end face of upper super-pressure wearing plate 41 is respectively lower end surface with upper base plate 1, biconvex curved surface ball
The upper surface of core 2 matches the structure of adaptation, and the upper and lower end face of lower super-pressure wearing plate 42 is respectively and biconvex curved surface core 2
Lower end surface, unidirectional damping plate 5 upper surface match the structure of adaptation.
In the present invention, 5 upper surface of unidirectional damping plate is provided with unidirectional dotted texture structure 51, the unidirectional point
Shape texture structure 51 is in the fine and closely woven distribution of concentric circles；The center of circle of concentric circles is located at the longitudinal direction of the unidirectional big damping friction pendulum support simultaneously
On center line；And along concentric circles radial direction, dotted texture structure 51 is distributed relative to the center of circle in symmetrical barb structure 5111；Hangnail
Structure 5111 unidirectionally arranges that puncture tip is not laid described towards the center of circle, and in the central area 512 of close center of circle certain distance
Barb structure 5111, as shown in Figure 3 and Figure 4.
As shown in figure 3, central area 512 is transition region, it is the center of circle middle section of unidirectional damping plate 5, and " ideal
State area ", herein, the coefficient of friction of unidirectional damping plate 5 and lower super-pressure wearing plate 42 are infinite close to 0.Following super-pressure is wear-resisting
Plate 42 is for left eminence to the right (center of circle direction) sliding, as shown in figure 4, lower super-pressure wearing plate 42 is in lesser coefficient of friction
Smooth a trip to its front end slips over central area 512 under μ 1, so touch right side hangnail region 511 when, lower superelevation
The rear end (left end) of wearing plate 42 is pressed to be detached from the hangnail region 511 in left side, then eminence moves to the right from lower, rubs with biggish
It wipes coefficient μ 2 " rushing slope ".Conversely, motion mode is symmetrical, unidirectionally, it may be assumed that suitable with lesser friction coefficient μ 1 from high to lower always
It is sliding, and hoist to slow down with biggish friction coefficient μ 2 from lower and climb, thus smooth return.
As shown in Figures 5 to 7, when structure meets with earthquake, biconvex curved surface core 2 can be relative to lower seat board 3 and lower seat board
The unidirectional damping plate 5 being arranged in 3 grooves is swung, when biconvex curved surface core 2 is swung to the left or to the right relative to unidirectional damping plate 5
When, since the puncture tip of the barb structure 5111 of the dotted texture structure 51 of 5 upper surface of unidirectional damping plate is directed towards dotted lines
The center of circle setting of structure 51, and the barb structure 5111 is not laid in the central area 512 of center of circle certain distance, make
When super-pressure wearing plate 42 must be descended to slide relative to unidirectional damping plate 5 to edge, coefficient of friction is larger, and can largely dissipate earthquake
The kinetic energy that energy, the natural period of extending structure, while earthquake generate can also be converted to the potential energy of support, further in potential energy
Under effect, 2 self-return of biconvex curved surface core, during return, since the puncture tip of barb structure 5111 is towards dotted line
The center of circle of line structure 51, and the barb structure 5111 is not laid in the central area 512 of center of circle certain distance, so that
When lower super-pressure wearing plate 42 slides relative to unidirectional damping plate 5 to center, coefficient of friction is smaller, to make biconvex curved surface core
2 reset residual volume is smaller, puts support for the unidirectional big damping friction and brings good Hysteresis Behavior.

Cloth, wherein each annulus is to be interrupted, is discontinuous, i.e., each annulus is separated into the small arc-shapeds of several interruption settings.
In seismic process, due to rubbing action between lower super-pressure wearing plate 42 and unidirectional damping plate 5, it can make lower super
The lower end surface of high-pressure anti-wear plate 42 is worn, and generates tiny wear particle；These tiny wear particles can pass through
Gap between small arc-shaped cleans up, to guarantee the smooth work of support.
In the present invention, super-pressure wearing plate refers to compression in the wear-resistant material of 60Mpa or more；Wherein, upper super
The MSM wearing plate that high-pressure anti-wear plate 41 can be strangled using German hair；Lower super-pressure wearing plate 42 can use polyether-ether-ketone material
Wearing plate, hardness is suitable, and wear-resisting property is good, and resistance to compression can reach 200Mpa；Unidirectional damping plate 5 can use Cr12 standard grinding tool
Steel, wearability are good；The dotted texture structure 51 of 5 upper surface of unidirectional damping plate can be obtained by existing artistic carving.
Foregoing description is only the description to the utility model preferred embodiment, is not to any of the scope of the utility model
It limits.Any change or modify equal that any those skilled in the art makes according to the technology contents of the disclosure above
It should be considered as equivalent effective embodiment, belong to the range of technical solutions of the utility model protection.
