Abstract

The invention relates to a tensile mechanism for stack rubber shock-insulating support seats, which is characterized in that stack rubber shock-insulating support seats are arranged between an upper structure and a lower structure, an upper reaction arm and a corresponding lower reaction arm are also arranged between the upper structure and the lower structure, the top end of the upper reaction arm is fixedly connected with the upper structure, and the bottom end of the lower reaction arm is fixedly connected with the lower structure; the bottom end of the other stack rubber shock-insulating support seat is connected with a cross arm of the bottom of the upper reaction arm, and the top end of the other stack rubber shock-insulating support seat is connected with a cross arm at the top of the lower reaction arm; the upper reaction arm, the lower reaction arm and the other stack rubber shock-insulating support seat form a reaction stack rubber shock-insulating support seat set. The invention has the advantages of simple structure and easy design and manufacture. The tensile mechanism can improve the tensile capability of shock-insulating layers of buildings, reduces the vertical displacement of shock-insulating layers, lowers earthquake response of the upper structure, and can be applied and popularized to large and wide structures.

Description

technical field [0001] The invention relates to the shock-isolation technology for buildings such as houses, bridges, expressways, etc., and further refers to the tensile mechanism of laminated rubber shock-isolation bearings. Background technique [0002] Seismic isolation technology can effectively reduce the seismic response of houses. In China, more than 500 engineering projects have adopted rubber seismic isolation bearings, including houses, bridges and expressways. The seismic isolation structure prolongs the period of the upper structure by arranging isolation bearings on the isolation layer, avoids the excellent period of the earthquake, and isolates the transmission of seismic energy to the upper structure. Additional energy-dissipating dampers can effectively dissipate seismic energy. [0003] The existing laminated rubber shock-isolation bearing is formed by interlacing vulcanization and bonding of thin rubber sheets and reinforcing plates, and has the character...
