ANTI-SEISMIC MECHANISM OF BUILDING

PURPOSE:To shut off vibration by installing a number of air bearings under the borne part of a building, sending high compressed air to these air bearings from a compressor in the event of an earthquake, and putting the borne part afloat in the air.

Summary:PURPOSE:To shut off vibration by installing a number of air bearings under the borne part of a building, sending high compressed air to these air bearings from a compressor in the event of an earthquake, and putting the borne part afloat in the air. CONSTITUTION:A groove 4 is formed in the undersurface of a foundation slab 3 of building mass 2, and air bearings 6 installed on a plate 5 are slipped into this groove 4. These bearings 6 are connected with a compressor 12 through a flexible hose 11, and output from a seismic sensing device is introduced to a computer, and a valve 13 is controlled. When an earthquake has occurred, the valve 13 is opened with the output from sensing, and the air in an air receiver 14 is released, and air is jetted out of the bearings 6, and by this pressure the whole mass 2 is put afloat from the foundation 1. Thus vibration is shut, and flame damage, etc., of building can be prevented.
