The invention provides an antiseismic product, and relates to an antiseismic building. Because 18 times of earthquakes above M7 and 1 to 2 times above M8 occur on the earth each year, people are in dire need of various antiseismic products. The invention provides the building capable of adopting automatic prevention measures to resist earthquakes. The entire building is designed by adopting the principle of tumblers; therefore, the building is just like a tumbler and does not collapse in a new environment when an earthquake causes ground cracks, sinking or land slides. Moreover, because the groundwork of the building is a solid hemispheroid or a laid down semicylinder, a cambered surface at the bottom can disperse the impact force of an earthquake on the building and changes the direct ofthe impact force, thereby ensuring that earthquake waves spread toward the periphery of the building; meanwhile, the earth generates powerful attraction on the inclined solid groundwork to force the building to recover and maintain erection or an inclined but not collapsed state, thereby guaranteeing the safety of human life and property. Therefore, the antiseismic building is suitable for schools, factories, city buildings and residential buildings and is particularly suitable for top-grade villas and scenic spot construction.
