Problems solved by technology

Therefore, although such a fastening method improves the strength and plastic deformation capacity of the joint, it is prone to irreversible damage such as concrete cracking, steel bar yielding or even fracture.
Especially for low-cap pile foundations, damage at the junction of the pile foundation and the cap is difficult to detect and repair

Abstract

The invention discloses a damping device used for connecting a pile foundation and a bearing platform and a construction method of the damping device. The damping device comprises the pile foundation and the bearing platform, wherein a groove matched with the pile foundation is formed in the bottom of the bearing platform; the top of the pile foundation is connected with an outer sleeve; an inner sleeve is arranged in the groove; the inner sleeve sleeves the outer sleeve; the outer sleeve is connected with the inner sleeve though an elastic connecting part; the outer sleeve, the inner sleeve and the elastic connecting part form a sealed space; and the sealed space is filled with a buffer layer. In the damping device, the elastic connecting part and the buffer layer effectively absorb earthquake energy, buffer the relative displacement between the pile foundation and the bearing platform, effectively prevent a superstructure on the bearing platform from overturn, and protect the joint of the pile foundation and the bearing platform against irreversible damage, including concrete cracking and reinforcement yielding; and after an earthquake is over, a damping connection structure for the pile foundation and the bearing platform resets under the elastic action of the buffer layer and the elastic connecting part so as to achieve the purposes of protecting the superstructure and guaranteeing the completeness of the foundation.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a shock absorbing device for connecting pile foundations and caps and a construction method thereof. Background technique [0002] With the rapid development of my country's urbanization and the shortage of urban land resources, the ever-emerging high-rise buildings, the ever-increasing demand for bearing capacity and the requirements for engineering quality all make piles with high bearing capacity, small settlement, flexible and convenient fabrication, and wide application conditions. The foundation has become the most widely used foundation form in the above fields. [0003] In the traditional pile foundation, the top of the pile foundation is embedded in the cap and the main reinforcement of the pile foundation is inserted into the cap for anchoring. Because the area of ​​the connection between the cap and the pile body changes most drastically in the ...
