Separate foundation with functions of seismic reduction and isolation

Abstract

The invention provides a separate foundation with the functions of seismic reduction and isolation. The separate foundation with the functions of seismic reduction and isolation comprises an upper-part foundation, a lower-part foundation and a side-surface support, wherein the lower-part foundation is located below the upper-part foundation, and connected with the upper-part foundation through a first seismic isolation support seat, and the seismic isolation support seat is used for supporting the upper-part foundation and absorbing a horizontal load and a vertical load; and the side-surface support comprises a side plate surrounding in the circumferential direction of the upper-part foundation, and a plurality of buffer support seats; and the side plate is connected with the side surfaceof the upper-part foundation through the buffer support seats and a second seismic isolation support seat sequentially, the buffer support seats and the second seismic isolation support seat support the side surface of the upper-part foundation, and are used for absorbing a tension-pressure stress in the horizontal direction of the upper-part foundation. The functions of seismic reduction and isolation are directly added to the foundation, and a building is capable of realizing the effects of seismic reduction and isolation only by being constructed on the foundation; the separate foundation overcomes the problems that a traditional independent foundation is too large in size and does not easily realize the effect of comprehensive seismic prevention.

Description

technical field [0001] The application relates to a detached foundation with functions of shock absorption and isolation. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Earthquakes are one of the most serious natural disasters faced by mankind. Many major earthquakes in history have caused major damage to bridges, building structures and other infrastructure, resulting in heavy casualties and huge economic losses. my country is one of the countries with the most serious earthquake disasters in the world. Therefore, how to improve the level of earthquake resistance and develop insulation-reducing Structures and devices with seismic function have become the focus of research in the field of earthquake engineering in my country. The ground vibration caused by the seismic wave is transmitted to the superstructure through the foundation, ca...

AI Technical Summary

Problems solved by technology

Traditional independent foundations are fixed together with the surrounding soil, and can be designed into different types of cross-sectional shapes and sizes according to needs, such as pile foundations, anchor foundations, enlarged foundations, caisson foundations, etc., but these foundations themselves have no The shock isolation function needs to realize the shock absorption and isolation function through the connection between the foundation and the superstructure. Usually, a shock-absorbing energy-dissipating support or a shock-isolation layer is set between the foundation and the superstructure, but this single shock-isolation The shock absorption effect of this method is not ideal for large earthquakes or even super earthquakes. Under the action of large earthquakes or even super earthquakes, bridges and building structures using existing shock absorption and isolation methods will still be damaged, and once damaged, they will be permanent. damaged beyond repair
