Detailed Description

Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the invention, its application, or uses. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element preceding the word comprises the element listed after the word, and does not exclude the possibility that other elements may also be included.

As shown in fig. 1-4, a building quakeproof base comprises a base body 1, wherein the base body 1 is sequentially provided with a bearing plate 2, a reinforcing rod 4, a supporting plate 3, a sliding plate 5, a limiting shaft 6 and a limiting plate 7 from top to bottom; the top of the seat body 1 is provided with a support plate 3, the support plate 3 is divided into two layers, the bottom layer of the support plate 3 is fixedly connected with the top of the seat body 1, and the top layer of the support plate is a damping rubber layer 301; the supporting plate 3 is upwards provided with a bearing plate 2, and the bearing plate 2 is fixed on the end surface of the top end of the sliding plate 5 through a plurality of oblique reinforcing rods 4; the end face of the bottom end of the sliding plate 5 is provided with four limiting shafts 6, strong springs 601 are arranged on the peripheries of the limiting shafts 6, and the strong springs 601 are fixedly connected with the tops of the limiting shafts 6; the limiting plate 7 is fixedly connected with the base 1, limiting holes are formed in the surface of the limiting plate and the corresponding positions of the limiting shafts 6, each limiting shaft 6 can penetrate through the corresponding limiting hole, and the bottom end of each limiting shaft 6 is provided with a limiting block 602.

As shown in fig. 2, the sliding plate 5 is not fixedly connected with the base body 1, and the sliding plate 5 has an aperture in the center, the aperture diameter of which is not smaller than the diameter of the base body 1.

As shown in fig. 4, the damping rubber layer 301 is a lead-containing rubber layer, which is hard and elastic, and has a plurality of hollow holes arranged therein at equal intervals to enhance the damping effect.
