The specific embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Illustrated among Fig. 1 the utility model an embodiment pendulum-type frictional damping bearing face generalized section, comprising: bearing topmost on middle liner plate 4 etc. between anchor plate 1, the upper sliding plate 3 that is connected with last anchor plate 1, lower support plate 7, said upper sliding plate 3 and the lower support plate 7 in the bearing bottom.Last anchor plate 1 usefulness shearing trip 2 connects with upper sliding plate 3; The structure of shearing trip 2 is convenient to install and substitute; Upper sliding plate 3 bottom surfaces are inlaid with slip wearing plate 5, and the stainless steel slide plate is set middle liner plate 4 end faces and slip wearing plate 5 forms friction pair, and the rotating function of bearing is provided; Form rotation slot between lower support plate 7 inside and the middle liner plate 4, be convenient to rotate.Middle liner plate 4 bottom surfaces are inlaid with antivibration wear resistant plate 6, and wearing plate 9 is equipped with in the side, and the stainless steel slide plate 8 that pastes on middle liner plate 4 and the lower support plate 7 forms friction pairs, and sliding function after the shake of bearing is provided.
Preferably, slip wearing plate 5 is the heat resistant type wearing plate with special sliding capability, for example modified ultra-high molecular weight polyethylene slip wearing plate with antivibration wear resistant plate 6.
Preferably; Lower support plate 7 set inside slip limiting grooves, the lower end of middle liner plate 4 is arranged in groove, and the side of middle liner plate 4 is provided with SF-1 wearing plate 9; The corrosion resistant plate slide plate 8 that is provided with lower support plate 7 sides forms the friction pair of stipulating glide direction, works to transmit horizontal force.Lower support plate 7 sides are provided with seismic shear piece 10 and are connected with middle liner plate 4, generally, can play the effect of limit levels power.When earthquake generation lateral force surpasses design load; Shearing piece 10 is cut off, and constraint is disengaged, and lower support plate 7 above structures will be moved along the slip stopper slot by integral body; The motion of formation pendulum model; Antivibration wear resistant plate 6 sharply strengthens friction factor because of speeding up, and rises thereby form higher temperature, and this will consume seismic energy greatly.Preferably, the upper surface of lower support plate 7 is designed to the large radius arc face, when the displacement of shake back takes place; The bearing superstructure is along with the pendulum model motion is elevated; Thereby convert seismic energy into potential energy, seismic forces is carried out damping, effectively reach the purpose of cutting down seismic forces through friction and potential energy.
