The upper surface and the lower surface of the spherical cap lining plate 7 are respectively embedded with and fixed with a sliding wear-resisting plate, and the sliding wear-resisting plate is contacted with the stainless steel plate to form a sliding friction pair. The sliding wear-resistant plate is generally made of polytetrafluoroethylene plates and the like, and has the characteristics of wear resistance and small friction coefficient. Through the friction pair formed by the sliding wear-resisting plate and the stainless steel plate, the friction pendulum support has small friction damping force in the sliding process, good wear resistance, long service life and no corrosion on the sliding friction surface.
The upper bracket 2 is located the support topmost, covers one deck corrosion resistant plate (go up corrosion resistant plate 5) on the survey sphere below the upper bracket 2, and corrosion resistant plate adopts the welding or riveting form to fix on upper bracket 2, forms the friction pair with the antifriction plate of spherical crown welt 7 upper surface.
