Strengthening the honeycomb tendons in the column by adhesively bonded steel plate

After the demolition of the column template, it is found that there is a serious honeycomb phenomenon in the column, and the strength of the concrete is relatively low. Steel plate reinforcement is carried out to ensure the durability and long-term safe use of the cylinder.

Project overview

After the demolition of the column template, it is found that there is a serious honeycomb phenomenon in the column, and the strength of the concrete is relatively low. Steel plate reinforcement is carried out to ensure the durability and long-term safe use of the cylinder.


Reason analysis and treatment scheme of column honeycomb ribs

On the surface of the column, the honeycomb and the main tendons are exposed. The main reason is that the construction of the longitudinal reinforcement is not dense when the concrete is poured and the construction is not dense. The strength of the concrete is reduced and the protection of the longitudinal reinforcement is seriously detrimental. In order to ensure the durability and long-term safety of the components, it is necessary to reinforce the components.


Because the surface of the cylinder is serious and the damaged area is large, in order to ensure that the position of the column honeycomb can be effectively filled with high strength material, it is to be chiseled for the parts with low strength of the concrete on the surface of the column, and the modified epoxy mortar is used to repair the honeycomb holes. 4mm steel plate is outsourced on the surface of the honeycomb column, and the steel plate is anchored with 8 chemical bolts. The cracks around the steel plate are sealed with epoxy mud, and then the epoxy resin is filled with pressure.
