Background technology
Frcition damper is as a kind of energy-dissipating device, and because its energy dissipation capacity is strong, load, frequency are little to its performance impact, and simple structure, draw materials easily, and be cheap, thereby have good application prospect.Particularly aspect the nearly fault earthquake reaction of control structure and the structural seismic response on the middle and senior level unique advantage is being arranged.The mechanism that frcition damper carries out vibration isolation to structure is: produce slippage or distortion under the pre-constant load of damper before the surrender of primary structure member, rely on friction or Damping work seismic energy, simultaneously, because lengthen natural vibration period after the malformation, reduce the earthquake input, thereby reached the purpose that reduces structural seismic response.The development of frcition damper starts from late 1970s, and for adapting to dissimilar building structure, Chinese scholars has been developed multiple frcition damper successively subsequently, and its frictional force size is easy to control, can determine by regulating the pretightning force size easily.At present, the frcition damper of research and development mainly contains: common frcition damper, Pall frcition damper, Sumitomo frcition damper, fricting shearing hinge damper, slide type slotted hole bolt joint damper, T core plate frcition damper, pseudo-viscous frictional damper, multi-stage friction damper and some friction composite energy dissipation devices.
If the power that frcition damper provides is excessive, just need to improve normal pressure, therefore can cause the parameter error of calculating larger, also cause easily energy consumption effect significantly to reduce, and also cause easily the inefficacy of device.Therefore need to carry out frcition damper further perfectly, mainly can by improving area of friction surface, improve the reliability of damper.
Summary of the invention
The object of the present invention is to provide a kind of lead dot locking frcition damper, improve damping force by quantity and the area that increases friction plate, increase initial stiffness by lead dot is set, and significantly increase power consumption.Adjust initial stiffness and damping by increase and decrease lead dot and replacing lead dot.Lead dot is locked frcition damper to be installed on architectural; can increase the integral rigidity of building structure when under normal condition, using; thereby when running into earthquake; the power consumption that utilizes lead dot to lock frcition damper can reduce the earthquake response of building structure, and building structure is played a very good protection.
