Problems solved by technology

[0003] Traditional friction pendulum bearings generally use metal casting technology, which is limited by casting technology and installation technical requirements. Most of the current friction pendulum bearings use single-column vibration isolation, so the size of the bearing is often limited
On the one hand, the radius of the friction pendulum support is small, which limits the vibration isolation effect of the friction pendulum. On the other hand, the construction process is complicated, which is not conducive to the control of construction time, and the metal is easy to rust and has poor durability.

Abstract

The invention provides an assembled local curved space and repeated rubbing swinging type shock insulation system, and relates to a rubbing swinging type shock insulation system. The system is characterized in that two groups of shock insulation pier columns are arranged in an array form and are divided into an upper shock insulation pier column layer and a lower shock insulation pier column layers; the upper shock insulation pier columns are corresponding to the lower shock insulation pier columns; every two adjacent upper shock insulation pier columns are fixedly connected with each two adjacent lower shock insulation pier columns through pier column connecting beams; the lower surfaces of the upper shock insulation pier column layers and the upper surfaces of the lower shock insulationpier column layers are arranged at intervals, and concave spherical surfaces are arranged as sliding surfaces; a sliding frame is arranged between the two sliding surfaces; a sliding frame column headis integrally manufactured on the sliding frame; and a sliding column cap is fixed to the outer end of the sliding frame column head and is matching contact with the end surface, on each sliding surface, of the corresponding shock insulation pier column. According to the system, the upper and lower sliding surfaces formed by the sliding frame and the two groups of shock insulation pier columns realize space repeated rubbing swinging, so that the shock insulation effect is improved; the assembling is simple and convenient; and the durability is improved.

Description

technical field [0001] The invention relates to a friction pendulum type shock isolation system, in particular to an assembled partial curved surface space complex friction pendulum type shock isolation system. Background technique [0002] Friction pendulum isolation technology has the characteristics of clear mechanism, simple structure, and good self-resetting performance, and has become one of the most effective isolation technologies. [0003] Traditional friction pendulum bearings generally use metal casting technology, limited by casting technology and installation technical requirements, most of the current friction pendulum bearings use single-column isolation, so the size of the bearing is often limited. On the one hand, the radius of the friction pendulum support is small, which limits the vibration isolation effect of the friction pendulum. On the other hand, the construction process is complicated, which is not conducive to the control of construction time, and ...
