[0011] In the description of the embodiments of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and other positional relationships are based on the orientation or positional relationships shown in the drawings or based on the customary arrangement of the product of the present invention when used. This is for the purpose of facilitating and simplifying the description of the present invention, and does not imply that the device or part must have a specific orientation, and therefore cannot be understood as a limitation on the present invention. Furthermore, the terms "first", "second", "third", etc. are used for distinction, and do not imply relative importance.

[0012] Additionally, the terms "horizontal," "vertical," "suspended," and the like do not require that a part be absolutely horizontal, vertical, or suspended, but may be slightly tilted. For example, "horizontal" simply refers to a more horizontal orientation relative to "vertical," but does not necessarily have to be perfectly horizontal, and may be slightly tilted.

[0013] In describing the embodiments of the present invention, "plurality" refers to at least two. In the description of the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installation", "attachment", "connection" and "coupling" should be understood in a broad sense. For example, they may be fixedly connected, detachably connected, or integrally connected. They may be mechanically connected or electrically connected. They may be directly connected, indirectly connected through an intermediate medium, or an internal connection between two parts. Those of ordinary skill in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0014] As shown in the drawing, the earthquake-resistant building structure includes a floor, the floor including a lower main layer 1 and an upper accessory layer 2, the upper accessory layer 2 being located above the lower main layer 1, and a buffer seismic absorption space 3 being provided between the upper accessory layer 2 and the lower main layer 1.

[0015] An anti-seismic device 4 is provided within the floor, and column reinforcing bars 11 are arranged on the upper part of the anti-seismic device 4. The anti-seismic device 4 includes a lower sleeve 5 and an upper sleeve 6, and a connecting ball 7 is provided between the upper sleeve 6 and the lower sleeve 5. A first ball recess 8 is provided at the bottom of the upper sleeve 6, and a second ball recess 9 is provided at the upper part of the lower sleeve 5, and the connecting ball 7 is fitted into the first ball recess 8 and the second ball recess 9. The lower sleeve 5 is located within the lower main layer 1, and the upper sleeve 6 is located within the upper appendage layer 2.

[0016] A plurality of movable slide plates 10 are provided in the second ball tank 9, and the plurality of movable slide plates 10 are arranged point symmetrically. The bottom of the connecting ball 7 is in contact with the upper end surface of the movable slide plate 10.

[0017] The upper part of the upper sleeve 6 is fixedly connected to the reinforcing bar 11 of the column. The distance between the upper sleeve 6 and the lower sleeve 5 is 150 mm, and the diameter of the connecting ball 7 is 400 mm.

The earthquake isolators installed at the supports of the upper and lower two layers are constructed with spheres embedded in stainless steel sleeves. The eight-way movable slide plate is not fixed in a specific direction. The outer steel columns are tied to the top of the upper sleeve, and are welded and concrete is poured. When an earthquake occurs, the connecting spheres move on the movable slide plate, resulting in the overall structure having the effect of the lower layer moving and the upper layer not moving.
