Embodiment Construction

[0023] The embodiment of the strengthening method of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] The present invention proposes a method and device for quickly reinforcing the damaged column. The reinforcing device used in the method - the prefabricated parts can be prefabricated in advance in the factory, and only need to splice the prefabricated parts to the dismantled part of the damaged column end during on-site construction , so as to achieve rapid reinforcement and replacement of the damaged zone at the end of the damaged column, and effectively restore the lateral stiffness and bearing capacity of the reinforced column. The specific implementation steps are as follows:

[0025] 1) The following will introduce the prefabrication and installation construction steps of prefabricated components in detail;

[0026] 2) Except that the process of connecting the prefabricated parts with the original column requir...

Abstract

The invention discloses a method for reinforcing a damaged reinforced concrete column by adopting a prefabricated component with sleeves. A prefabricated reinforced concrete component (1), the sleeves(2), embedded steel bars (3) with anchor heads and post-cast strips (4) are mainly included. The prefabricated reinforced concrete component is composed of pre-buried longitudinal bars, pre-buried stirrups, constructed pulling bars and concrete. The method comprises the steps that the reinforce concrete with the damaged plastic hinge at the bottom end of the concrete column is dismantled, the prefabricated reinforced concrete component replaces the dismantled concrete, the joint is integrally connected with the original column through the post-cast strips, and finally the column with the improved performance after reinforcing is formed. According to the method, the prefabricated component is adopted for assembling and reinforcing the damaged reinforced concrete column on site, the damagedpart at the column end is quickly dismantled and reinforced, all the prefabricated components can achieve industrialized production, on-site assembling and connection reduces the workload of wet construction on site, the reinforcing efficiency is effectively improved, the quality of reinforcing construction can be easily ensured, and the new concept that an assembling method is adopted for reinforcing the damaged structure is shown.

Description

technical field [0001] The invention relates to the technical field of building structure reinforcement, and relates to a rapid reinforcement method, in particular to a method and device for rapidly reinforcing the damaged area of ​​a plastic hinge of a reinforced concrete column by using prefabricated components. Background technique [0002] A large number of buildings in my country are located in earthquake zones, and earthquakes can cause serious damage to building structures. For frame structures, the plastic hinge at the end of the column under earthquake is a common damage mode. The traditional reinforcement method has the disadvantages of large amount of wet work on site and low reinforcement efficiency, and the degree of improvement of the stiffness and strength of the damaged column is limited. In view of this, the present invention attempts to improve the reinforcement efficiency and effect of damaged columns, and mainly relates to a method and device for reinfor...
