Abstract

The invention belongs to the technical field of building seismic isolation supports, and discloses an anti-overturning friction pendulum seismic isolation support and an assembly method thereof. The anti-overturning friction pendulum seismic isolation support mainly has the technical features that an upper support plate and a lower support plate are included, the upper surface of the lower supportplate is provided with a lower swing body formed by a lower swing body bottom plate, a sliding lining plate, a ball hinge with a column head on the upper part and a ball crown on the lower portion and a ball hinge cover plate, the lower swing body bottom plate is provided with a transverse lower guide bar, the lower support plate is provided with a lower tensile guide rail, the top surface of thesliding lining plate is in spherical contact with the bottom surface of the ball crown, the top surface of the ball crown is in spherical contact with the inner wall of the ball hinge cover, the ballhinge cover is in threaded connection with the lower swing body bottom plate, an upper swing body is arranged below the upper support plate, the upper swing body is provided with a longitudinal upperguide bar, the upper support plate is provided with an upper tensile guide rail, and a column hole at the lower end of the upper swing body is in threaded connection with the column head. The anti-overturning friction pendulum seismic isolation support can slide horizontally in all directions, can withstand the pressure and tension during an earthquake and prevents a building from overturning.

Description

technical field

[0001] The invention belongs to the technical field of building shock-isolation supports, in particular to an anti-overturning friction pendulum shock-isolation support and an assembly method thereof. Background technique

[0002] In recent years, frequent earthquakes have brought huge losses to the country and the people. Therefore, it is particularly important to ensure the smooth flow of roads when the earthquake comes, and the safety of schools, hospitals, shopping malls and other crowded areas and lifeline projects. Friction pendulum isolation bearings have unique advantages such as the isolation period is not affected by gravity loads, and product quality is easy to control. They are more and more widely used, but the existing building friction pendulum isolation bearings cannot bear tension, and some can The applicability of the friction pendulum bearing bearing the tension cannot meet the requirements of use, which restricts the use of the friction p...
