The Sixth Embodiment

An antiseismic supporting base body 100 e of the present invention is shown in FIG. 8. The elements of this embodiment illustrated in this Fig. are similar to those in the fourth embodiment.

The surface area of the external surface of the antiseismic body of the antiseismic supporting base body is decreased continuously or discontinuously from top to bottom, and the strongest antiseismic strength of the antiseismic body is located in the central axis of the antiseismic body, so that the antiseismic supporting base body in this present disclosure has advantages as follows:
(1) When the earthquake happens, the earthquake wave from the seismic source underground radiates to the ground. And while this earthquake wave is attacking the antiseismic supporting base body mentioned above, because the shape of the antiseismic body is similar to an inverted cone or to an inverted pyramid, the energy of the earthquake wave is proceeding along the side surface of the antiseismic body to the ground and is decreasing progressively, so that it is released to the outside of the periphery of the antiseismic body effectively. So the fracture or the overmuch motion of the conventional base body because the earthquake wave directly contact to a large bottom surface of the base body will not happen. Also, the friction between the antiseismic body and the stratum increases, and the ability of the antiseismic body to bear the load and the stress resulted form the load raises. When the soil is liquefied, the antiseismic supporting base body is possibly to sink but hardly to collapse.
(2) Because the strongest antiseismic strength of the antiseismic body of the antiseismic supporting base body is located in the central axis of the antiseismic body, the centre of gravity of the building can be set in higher position moderately, especially in the tower-style building. In the condition that using the same quality or the same quantity construction material, the antiseismic supporting base body in this present disclosure is better in some performances such as the stability, the antiseismic ability, and the storm-proof ability.
(3) By using the soil nail or the anchor pole, the supporting efficiency of the antiseismic supporting base body increases. The soil nail or the anchor pole is suitable used in the area where the earthquake happens often or the water level of the groundwater is lower, or in the natural foundation.
(4) The antiseismic supporting base body can be considered as an assembly unit and be extended by a plurality of the assembly unit so as to become a structure of which antiseismic strength is better to satisfy the requirement for the building of which antiseismic strength must be higher.
(5) An ancillary bearing is provided at one or more positions selected from a group including the bottom of the main pile, the bottom of the subsidiary pile, and the bottom of the ancillary pile, wherein the shape of the ancillary bearing is similar to an inverted cone or to an inverted pyramid. It increases the friction between the antiseismic body and the stratum and also increases the ability of the antiseismic body to bear the load and the stress resulted form the load.
As can be appreciated from the above embodiments, the antiseismic supporting base body of the present invention has industry worth which meets the requirement for a patent. The above description should be considered as only the discussion of the preferred embodiments of the present invention. However, a person skilled in the art may make various modifications to the present invention. Those modifications still fall within the spirit and scope defined by the appended claims.
