Problems solved by technology

[0004] The current swing column system has the following problems: 1. At present, the self-resetting function of the swing column is mainly provided by prestressed unbonded steel strands, which is not only difficult to construct, but also difficult to guarantee the construction quality; Reliable connection cannot guarantee the lateral stiffness of the swing column, which affects normal use; 3. It is difficult to repair after the earthquake

Abstract

The invention discloses a connection structure between a reinforced concrete swing column and a foundation, comprising a reinforced concrete foundation, a reinforced concrete abutment and a reinforced concrete column, a first steel plate is pre-embedded at the bottom of the reinforced concrete column, and a second steel plate is pre-embedded at the top of the reinforced concrete abutment. Stiffening ribs are provided on the bottom of the first steel plate, and horizontal limit springs are arranged between the stiffening ribs and the second steel plate. Screws are pre-embedded on the reinforced concrete foundation, and a screw is installed on each screw above the first steel plate. An upper steel plate is respectively fixed on the bottom surface of each nut, and a vertical spring is respectively arranged under each upper steel plate. The upper ends of each vertical spring are respectively fixed on the upper steel plate below the corresponding nut, and the lower ends of each vertical spring are welded to on the steel plate. The connection structure between the reinforced concrete swing column and the foundation of the present invention has the advantages of simple structure, low cost, convenient construction, better self-resetting function, convenient later maintenance and reinforcement, and convenient repair after the earthquake.

Description

technical field [0001] The invention relates to an anti-seismic structure of civil engineering, in particular to a connection structure between a reinforced concrete swing column and a foundation. Background technique [0002] The traditional anti-seismic concept generally enhances the anti-seismic capability of the structure by increasing the stiffness, strength and ductility of the structure, but this approach usually leads to serious damage to the structure after the earthquake and difficult repairs. In recent years, rocking structural systems have become one of the important research directions in the field of earthquake engineering because they can significantly reduce the post-earthquake damage of structures. At present, there are various implementation forms such as swing column system, swing wall system, combination of swing structure and energy dissipation and shock absorbing device. [0003] The so-called swing column system, for frame structures, can relax the co...
