Embodiment Construction

[0036] The following is a further detailed description of a three-dimensional shock-isolation pedestal with multiple defense lines according to the present invention mainly in conjunction with the accompanying drawings and specific embodiments.

[0037] Such as Figure 1-Figure 6 As shown, the present invention provides a three-dimensional shock-isolation pedestal with multiple lines of defense, including:

[0038] Pedestal bottom plate 1, for placing on the ground or other stable planes;

[0039] Four support columns 2 are distributed in a matrix, and the bottom ends of each support column 2 are fixed on the base plate 1;

[0040] The top plate 6 is used to place buildings, equipment or cultural relics waiting to be protected, and a top box 5 is fixed on the bottom of the top plate 6;

[0041] Four multi-defense horizontal shock-isolation units 3, each multi-defense horizontal shock-isolation unit 3 is horizontally connected between a side of a support column 2 and a side o...

Abstract

The invention provides a three-dimensional seismic isolating pedestal with multiple defence lines. The three-dimensional seismic isolating pedestal with multiple defence lines comprises a pedestal bottom plate, at least three supporting columns and a top plate, wherein the bottom end of each supporting column is fixed on the pedestal bottom plate; the top plate is used for placing an object to be protected; a top box is fixed on the bottom surface of the top plate; a multi-defence line horizontal seismic isolating unit is horizontally connected between the side surface of each supporting column and the corresponding side surface of the top box; a multi-defence line vertical seismic isolating unit is vertically connected between the top end of each supporting column and the bottom surface of the top box; each of the multi-defence line horizontal seismic isolating units and the multi-defence line vertical seismic isolating units is provided with a plurality of pieces of thin and long soft steel and a plurality of pieces of short and thick soft steel; the first defence line is formed by the thin and long soft steel and the second defence line is formed by the short and thick soft steel; and when a structure which is subjected to seismic isolating is at different seismic action levels, a plurality of seismic isolating defence systems can be arranged on a supporting seat independently, the working states and the control levels of the seismic isolating supporting seat at different levels are different, so that the three-dimensional seismic isolating pedestal with the multiple defence lines has higher adaptability.

Description

technical field [0001] The invention relates to the field of shock absorption and energy consumption of buildings, equipment and cultural relics in collections, in particular to a three-dimensional shock-isolation pedestal with multiple lines of defense. Background technique [0002] China is located between two major seismic belts - the Eurasian seismic belt and the circum-Pacific seismic belt, and is one of the countries most severely affected by earthquakes in the world. Historically, strong earthquakes of magnitude 6 or above have occurred many times in the Yangtze River Delta and the Pearl River Delta. In the Beijing-Tianjin-Bohai Rim region, in the past 300 years, an average of 7 magnitude or more earthquakes have occurred every 44 years. With the acceleration of urbanization, a large amount of national wealth is rapidly concentrated in cities and urban agglomerations. And more than one-third of my country's built or planned urban agglomerations are located in areas w...
