Three-dimensional shock absorbing and isolating device and mounting construction method thereof

Abstract

The invention relates to a three-dimensional shock absorbing and isolating device and a mounting construction method thereof. The three-dimensional shock absorbing and isolating device comprises a laminated rubber horizontal shock isolating pad arranged on the upper portion and a laminated polyurethane rubber vertical shock absorbing pad arranged on the lower portion; the upper end of the horizontal shock isolating pad is connected with the lower end of an upper buttress through fixing bolts; the lower end of the horizontal shock isolating pad is connected with the upper end of the vertical shock absorbing pad through fixing bolts; and the vertical shock absorbing pad is connected with the upper end of a lower buttress through fixing bolts. According to the three-dimensional shock absorbing and isolating device and the mounting construction method thereof, the manufacturing technology is simple, processing and forming are facilitated, and the cost is low; the size is small, the weightis low, and transportation and mounting are facilitated; and the horizontal shock isolating and vertical shock absorbing effects are significant, under the premise that vertical small deformation is guaranteed, the vertical earthquake action of a superstructure is effectively reduced, meanwhile, a damper can also achieve the vertical shock absorbing action, and the vertical shock absorbing capacity is greatly improved.

Description

technical field [0001] The invention relates to a building disaster prevention and reduction device, in particular to a three-dimensional shock reduction and isolation device and an installation and construction method. Background technique [0002] At present, although building isolation technology has been widely used, the relatively mature technology mainly focuses on minimizing or isolating horizontal earthquake action. According to Article 4.1.5 of CECS126:2001 "Standard Rubber Bearing Seismic Isolation Technical Regulations": According to the observation records of the vertical acceleration of multiple isolation houses in the Hanshin earthquake in Japan, and the domestic shaking table test results for the isolation structure model , the vertical acceleration response of the isolated structure does not change significantly compared with the vertical acceleration of the ground; therefore, for important buildings and infrastructures in high-intensity areas and near the ep...
