Above-mentioned height-adjustable friction-pendulum shock-insulation support, cap bottom, described top is a smooth sphere, the convex spherical radius on the described adjusting screw(rod) is less than smooth sphere.
This technical scheme has following beneficial effect:
1. the present invention can be used for resisting near the slowly following contingent vibrations consumingly of relative motion and tomography up and down of tomography.
2. natural active fault or underground coal mining cause face of land differential settlement, cause building structure inclination, wall crazing, and this is a common practice.Theoretical and experimental results show that shock insulation can resist strong motion, and adjustable for height bearing can adapt to relative settlement, resists relative settlement by the adjustment of shock insulation layer geometric parameter.Newly constructed house can be taked to dodge, or design the time just takes the present invention also can avoid above-mentioned damage.For build up and occur tilting, the house of wall crazing can take the present invention to administer, and can ensure the safe in utilization of house, compares with dismounting, moving, uses the present invention and can save a large amount of funds, also can reduce the relevant trouble of many moving.
3. if the house breakage is owing to differential settlement causes, by height-adjustable friction-pendulum shock-insulation support the many position jackings of sedimentation are returned so, make that absolute altitude returns to original design level substantially at the bottom of the housing base, height-adjustable friction-pendulum shock-insulation support is installed on the stake top, bear upper load, and reliably connect, be used to resist following contingent earthquake and differential settlement.
4. polytetrafluoroethylene (PTFE) plate thickness 0.8~1.2mm of the present invention between top cap and adjusting screw(rod), because its friction factor is very little, can play the effect of shock insulation layer.
5. the condition that is suitable for of the present invention satisfies manyly more for following condition, effect of the present invention is good more:
(1). more complete apron piece is arranged.
(2). it is more that the superstructure structure connects (as collar tie beam, constructional column etc.).
(3). the maximum settlement difference is less than 3%.
(4). the house number of plies is below 8 layers.
Description of drawings: accompanying drawing 1 is the structural representation of this product.
The specific embodiment:
