Reinforcing method of concrete column

Abstract

The invention discloses a reinforcing method of a concrete column. The reinforcing method is characterized in that steel plates are mounted on 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 and reinforcing steel plates are welded together, so that the steel plates on the two opposite side faces are connected into a whole body; in a concrete pouring process, poured concrete is pre-pressed through a pressurizing device; before the concrete is poured, a template supporting method is as follows: the steel plates mounted on the two opposite side faces of the concrete column are directly used as templates for pouring the concrete and the other two side faces of the concrete column adopt wood templates; each wood template is formed by splicing small templates; grooves are formed in connection parts of the wood templates and the steel plates; grooves are formed in the middles of the wood templates and steel square pipes are mounted in the grooves; the steel square pipes are arranged along the length direction of the wood templates; a unidirectional air valve is mounted at the end part of the steel square pipe of each small template. Template hoops are arranged on the outer surfaces of the wood templates and are used for connecting the steel plates and the wood templates to form a whole body; annular steel sleeves are arranged on the outer surfaces of the wood templates and a steel die, and an air pressure device is connected with air inlet flanges of the annular steel sleeves.

Description

technical field [0001] The invention relates to a reinforcement method, in particular to a reinforcement method for a concrete sick 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 seriously affected.
