Reinforcing construction method for defective concrete column

Abstract

The invention discloses a reinforcing construction method for a defective concrete column. The reinforcing construction method is characterized in that steel plates are arranged on the two opposite side faces of the concrete column, the other two side faces of the steel plates adopt steel batten plates, the steel batten plates are welded to the reinforcing steel plates, the steel plates on the two opposite side faces are connected into a whole, and in the process of pouring concrete, a pressurizing device is used for pre-pressurizing concrete which is poured later; and a method for supporting formworks before pouring the concrete comprises the following steps that the steel plates which are arranged on the two opposite side faces of the concrete column directly serve as the formworks for pouring the concrete, the other two side faces adopt timber formworks which are formed by splicing small formworks, grooves are formed in the portions, connected with the steel plates, of the timber formworks, the middle portions of the timber formworks are provided with grooves, the grooves are internally provided with steel square pipes, the steel square pipes are arranged along the whole lengths of the timber formworks, and the end portion of the steel square pipe of each small formwork is provided with a one-way air valve. Formwork hoops are arranged outside the timber formworks, and the steel plates and the timber formworks are connected into a whole through the formwork hoops. An annular steel sleeve is arranged outside the timber formworks and the steel plates, and an air pressure device is connected with an air inlet flange of the annular steel sleeve.

Description

technical field [0001] The invention relates to a reinforcement construction method, in particular to a reinforcement construction method for a concrete diseased column. Background technique [0002] When common quality defects such as honeycomb holes appear in the concrete column, the bearing capacity will be greatly affected, and the concrete column must be reinforced to increase the bearing capacity of the concrete column. The traditional method of strengthening concrete diseased columns is steel plate reinforcement, that is, steel plates are set around the concrete diseased column for reinforcement, and concrete is poured between the steel plate and the concrete diseased column. Due to the inconsistent deformation of the post-cast concrete and the original concrete, and the rigidity of the steel plate and concrete There is a huge difference, both the steel plate and the added concrete are difficult to play a role when the force is applied, and the reinforcement effect is...
