Abstract

The invention involves a vertical anti-plucking friction pendulum bearing, belongs to architecture structures shock insulation and shock absorbing control field. It mainly consists of the lower connecting steel plate (13) which upper surface is equipped with chute (8), slide block (7), upper cover board (4) and anti-plucking baffle (5). The upper cover board (4) consists of the upper connecting steel plate (9) and lower blocks (10), the both are fixed and connected into one unit. The upper hemispherical protrusion of slide block (7) is matched with the hemispherical groove of lower block (10), the slide block (7) can slide along the bottom of the chute (8) by the driving of lower blocks (10). Compared with prior technology, the invention adds anti-plucking baffle (5) between the upper connecting steel plate (9) and the lower block (10), so the bearing ha strong anti-plucking capacity on the vertical direction, it ensures the structure security under the action of strong earthquake, multidimensional earthquake and wind loads. The invention has simple structure and strong practicability, and it is easy for production and installation.

Description

technical field [0001] The invention relates to a vertical anti-pull type friction pendulum bearing, which belongs to the field of shock-isolation and shock-absorbing control of building structures. Background technique [0002] FPS (Friction Pendulum System), also known as friction pendulum system, is an effective dry friction slip isolation system, which was first proposed by Dr. Victor Zayas of the United States in 1985. The main principle of FPS isolation and energy dissipation is to isolate the structure itself from the ground, and use the design period of the sliding surface to extend the vibration period of the structure, so as to greatly reduce the dynamic amplification effect of the structural earthquake; in addition, the FPS sliding surface can also be used The friction between the surface and the slider consumes a large amount of seismic energy to achieve the purpose of reducing the input of seismic force. The FPS friction pendulum sliding isolation method is low...
