Abstract
The present invention provides a system and method for protecting buildings from damage due to seismic waves. The system comprises a bed of sand contained between two layers of polymer membrane, upon this sand bed a rests a first concrete slab, this first concrete slab supports, through a plurality of coil springs and shock absorbers, a second concrete slab. The structure to be protected is attached to the upward facing surface of the second concrete slab. In the event of an earthquake, the sand bed acts to slow the propagation of seismic waves, while the plurality of springs and shock absorbers isolates the structure from ground movements caused by the waves.
Claims38
An anti-seismic support for protecting a structure from seismic shock comprising:
- a) a first layer of plastic film;
- b) a sand bed deposited on the layer of film to absorb shocks, trembling and land movement, and to slow down secondary waves and primary waves;
- c) a second layer of plastic film on top of the sand bed to keep the sand bed moist;
- the first layer and second layer of plastic film being sized to extend beyond the sand on each side of the sand bed;
- d) a first reinforced concrete slab cast over the second layer of plastic film;
- e) a plurality of maraging steel springs and shock absorbers in an array of rows and columns across the first reinforced concrete slab;
- and
- f) a second concrete slab on top of the array of springs and shock absorbers;
- the structure to be protected being mounted on the second concrete slab.
A method of constructing an anti-seismic support for a building, comprising the steps of:
- a) preparing the land on which the structure is to be built;
- b) placing a first layer of plastic film on the cleared land;
- c) depositing a sand bed on the layer of film to absorb shocks, trembling and land movement, and to slow down secondary waves and primary waves;
- d) placing a second layer of plastic film on top of the sand bed to keep the sand bed moist;
- the first layer and second layer of plastic film being sized to extend beyond the sand bed on each side of the sand bed;
- e) casting a first reinforced concrete slab cast over the second layer of plastic film;
- f) placing a plurality of maraging steel springs and shock absorbers in an array of rows and columns across the first reinforced concrete slab;
- g) placing a second concrete slab on top of the array of springs and shock absorbers;
- and
- h) mounting the structure to be protected on the second concrete slab.
