Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as Figure 1-5 Shown: a friction pendulum support equipped with a ring-shaped steel plate, including an upper anchor rod 1, an upper support plate 2, a high-strength bolt 3, a spherical crown 4, an upper wear-resistant plate 5, an annular steel plate 6, and a lower wear-resistant plate 7 , the lower bearing plate 8, the lower anchor rod 9 and the sliding surface 10;
[0026] The upper support plate 2 is in cylindrical contact with the upper wear plate 5, the lower support plate 8 is in cylindrical contact with the lower wear plate 7, and the spherical cap 4 is in contact with the upper support plate 2, The contact between the lower support plates 8 is spherical contact, the connection between the upper part of the spherical cap 4 and the upper wear-resistant plate 5 is a hinge joint that can rotate relative to each other, and the u...

The invention discloses a friction pendulum support equipped with annular steel plates. The friction pendulum support comprises upper anchoring rods, an upper support plate, high-strength bolts, a ball crown, an upper wear-resisting plate, the annular steel plates, a lower wear-resisting plate, a lower support plate, lower anchoring rods and a sliding surface, wherein the upper support plate and the upper wear-resisting plate are in cylindrical surface contact; the lower support plate and the lower wear-resisting plate are in cylindrical surface contact; the ball crown is in spherical surface contact with the upper support plate and the lower support plate, the upper part of the ball crown is hinged with the upper wear-resisting plate, the annular steel plates are mounted between the upper support plate and the lower support plate, the upper ends of the annular steel plates are anchored at the bottom of the upper support plate by the high-strength bolts, and the lower ends of the annular steel plates are anchored at the top of the lower support plate by the high-strength bolts. The friction pendulum support can provide an additional damping ratio for the structure, change the natural vibration period of the upper structure, reduce the structure earthquake response, limit relative displacement between the upper structure and the lower structure and finally prevent the upper part and the lower part from being separated, so that the upper structure cannot be overturned.
Description
technical field [0001] The invention relates to an anti-seismic and anti-shock isolation technology, in particular to a passive energy consumption anti-shock isolation and position-limiting friction pendulum support equipped with an annular steel plate. Background technique [0002] The self-balancing ability of the traditional friction pendulum support is poor under small earthquakes; under moderate and strong earthquakes, the ordinary movable friction pendulum support swings relatively large, and the friction pendulum equipped with shear keys will have sudden force changes during the stress process , the superstructure is easily thrown out. In the prior art, there is a lack of a friction pendulum bearing with better shock absorption and energy dissipation capabilities. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a friction pendulum support equipped with an annular steel plate in...
