Pass through technique scheme; The anti-pulling friction pendulum support of the utility model is compared with common friction pendulum support; Structure, cost and production are installed and are changed not quite; But on the basis of the repertoire that can realize common friction pendulum support, possessed the ability of good vertical anti-pulling, thereby the more common friction pendulum support of its range of application obtains augmentation.
Description of drawings
The accompanying drawing that constitutes the part of the utility model is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 shows the front view of anti-pulling friction pendulum support of an embodiment of the utility model; And
Fig. 2 shows the vertical view of anti-pulling friction pendulum support of an embodiment of the utility model.
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.
The lateral view of anti-pulling friction pendulum support of an embodiment of the utility model has been shown among Fig. 1.The technical scheme that the friction pendulum support of the utility model adopts is: comprise rotation seat board 6, the slip seat board 7 that connects substructure, the slip wearing plate 5 that is folded in the two sphere liner plates 4 that rotate between seat board 6 and the slip seat board 7, the rotation wearing plate 3 that is positioned at pair sphere liner plate 4 upper surfaces and soffit that connect superstructure, be arranged on the slip seat board 7; The limiting plate 2 that limit rotation seat board 6 moves, and the shearing resistance power consumption pin 1 that connects slip seat board 7 and limiting plate 2.Preferably, rotate the modified ultra-high molecular weight polyethylene plate of wearing plate 3 employing low-friction coefficients, the edge cover is adhered on the concave spherical surface that rotates seat board 6 soffits, forms the pivoting friction pair with the small curvature radius sphere of two sphere liner plate 4 upper surfaces.Slip wearing plate 5 adopts the single material heat resistant type wearing plate or the modified ultra-high molecular weight polyethylene plate of appropriate friction factor, and the edge cover is adhered to the larger radius of curvature sphere of two sphere liner plate 4 soffits, forms sliding friction pair with the concave spherical surface of slip seat board 7 upper surfaces.Limiting plate 2 is fixed on the slip seat board 7 through shearing resistance power consumption pin 1.Rotate seat board 6 lower edges and be provided with anti-pulling button 8, form buckle structure with limiting plate 2 matched in clearance on vertical.
The friction pendulum support that the utility model is related; With present friction pendulum support compared with techniques; Difference is: the first, increased anti-pulling button 8 structures of anti-pulling in the lower edge of rotating seat board 6, and it is not only spacing in the horizontal direction that 2 pairs of limiting plates rotate seat board 6; Through snap close to anti-pulling button 8, vertically also carried out spacing.The second, increased on the slip seat board 7 the fixedly height of back-up ring 9 structures, fixedly back-up ring 9 main rising are installed limiting plate 2 and anti-fall beam action in earthquake, and too high at ordinary times height will increase the bearing cost, even influence the bearing rotating property.Increasing it here highly is to anti-pulling button 8 leaving spaces that rotate seat board 6.
Referring to Fig. 2; When limiting plate 2 is ring-type with rotation seat board 6 matched in clearance place in the horizontal direction; The anti-pulling button that promptly rotates seat board 6 is the anti-pulling clasp 8 this moments, and limiting plate 2 has limited the displacement of rotating seat board 6 all direction vertical and horizontal, and bearing is a fixed.When the matched in clearance place is two parallel edge strip shapes; 2 of limiting plates have limited and have rotated 6 one vertical or horizontal displacements of direction of seat board; This moment, bearing was unidirectional horizontal or longitudinal type; The anti-pulling button 8 that promptly rotates seat board 6 is anti-pulling button limit this moment, with the buckle structure of limiting plate 2 be applicable to fixing unidirectional vertically, the lateral type bearing.
Under normal circumstances; Limiting plate 2 and rotation seat board 6 matched in clearance; Comprise horizontal direction and the facade and vertical direction and anti-pulling clasp 8 upper surfaces that rotate seat board 6; When realizing, allow to rotate seat board 6 and can realize rotating function smoothly within the specific limits the level and vertical spacing of rotating seat board 6.Rotate power that seat board 6 transmits through limiting plate 2 less than shearing resistance power consumption pin 1 shearing resistance, bearing can only be realized rotating, and can not slide basically in the horizontal direction, spacingly has an anti-pulling ability what vertically also receive limiting plate 2.The size of concrete anti-pulling ability, according to actual needs, the intensity that resistance to plucking clasp 8 and limiting plate 2 are set gets final product.
Under earthquake conditions; Rotate seat board 6 and cut off shearing resistance power consumption pin 1 through the power of limiting plate 2 transmission; Power consumption pin 1 consumes part energy and is cut off; The structure on two sphere liner plates 4 and top thereof begins to consume energy through the sliding friction pair slip that slip wearing plate 5 and slip seat board 7 are formed, and prolongs the natural vibration period of institute's bearing structure thing bridge, building etc. etc. simultaneously, realizes the shock-absorbing function of friction pendulum support.
Anti-pulling friction pendulum support according to the utility model has following beneficial effect:
Simple in structure, cost is low, installs simple and easy.On the basis of the repertoire that can realize common friction pendulum support, possessed the ability of good vertical anti-pulling, thereby the more common friction pendulum support of its range of application obtains augmentation.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
