Blocking type grinding shock isolation device

Abstract

The invention provides a blocking type grinding shock isolation device. The device comprises a lower buttress, a top plate, a blocking unit and multiple limiting parts. A groove is formed in the top face of the lower buttress, the top plate is located above the lower buttress, the blocking unit is arranged between the lower buttress and the top plate, the blocking unit comprises multiple first bearing parts and multiple second bearing parts, the top ends of the multiple first bearing parts are fixedly connected with the top plate, the bottom ends of the first bearing parts extend into the groove and are in sliding connection with the lower buttress, the second bearing parts are evenly arranged on the outer portions of the first bearing parts, two ends of the second bearing parts are fixedly connected with the top plate and the lower buttress, the limiting parts are arranged in the groove and are fixedly connected with the lower buttress, and the limiting parts are arranged between thefirst bearing parts and are annularly distributed. The device has the advantages of being obvious in shock isolation, simple in structure, economical, practical, easy and convenient to construct and the like. The problems that when an existing shock isolation technology is applied to a building structure, cost is high, design is complex, and construction difficulty is large are solved.

Description

technical field [0001] The invention relates to the technical field of building shock isolation, in particular to a blocking type grinding shock isolation device. Background technique [0002] Seismic isolation technology is one of the most effective measures to reduce the damage of structural earthquakes. The basic idea is to install a flexible isolation layer with sufficient reliability between the foundation and the superstructure to prolong the natural vibration period of the structure and increase the damping to reduce the seismic energy. passed to the upper structure. [0003] In actual earthquakes, the damage to buildings in villages and towns is often the most serious, and the threat to life and property safety is also the greatest. Frame structure is one of the main structural forms of buildings in villages and towns, and its foundation usually adopts an independent foundation. The current anti-seismic code proposes that the base isolation technology suitable for f...

Problems solved by technology

[0003] In actual earthquakes, the damage to buildings in villages and towns is often the most serious, and the threat to life and property safety is also the greatest. Frame structure is one of the main structural forms of buildings in villages and towns, and its foundation usually adopts an independent foundation. In the current anti-seismic code, it is proposed that the base isolation technology suitable for frame structures mainly adopts rubber isolation bearings. Because rubber isolation bearings are expensive, the connection structure and construction technology are complicated, they are not suitable for promotion in village and town buildings.
