Abstract

The invention provides a concrete beam repairing structure and a repairing method suitable for the concrete beam repairing structure, and belongs to the technical field of building structures. The device comprises a concrete beam, a U-shaped steel plate, plate bottom anchoring steel plates and plate top anchoring steel plates, a concrete plate is connected to the upper portion of the concrete beam, the U-shaped steel plate sleeves the outer surface of the concrete beam, a grouting layer is formed between the U-shaped steel plate and the concrete beam, and the plate bottom anchoring steel plates are arranged on the bottom surfaces of the concrete plate on the two sides of the concrete beam. The U-shaped steel plate is arranged above the concrete plate, the plate bottom anchoring steel plate is connected with the edge of an opening of the U-shaped steel plate in a welded mode, the plate top anchoring steel plate and the plate bottom anchoring steel plate are correspondingly arranged above the concrete plate, and the plate top anchoring steel plate and the plate bottom anchoring steel plate are fixedly connected through a plurality of opposite-pull screws which are evenly arranged at intervals. And the section strength and rigidity of the beam are enhanced.

Description

technical field [0001] The invention relates to a concrete beam repair structure and a repair method applicable to the structure, and belongs to the technical field of building structures. Background technique [0002] The existing reinforcement methods of reinforced concrete beams mainly include increasing section method, bonding steel reinforcement and bonding fiber rechecking material reinforcement. [0003] The increasing section method increases the bearing capacity and stiffness of the original concrete beam by increasing the section area of ​​the original concrete beam and adding longitudinal reinforcement bars and stirrups. The specific method of strengthening the concrete column by increasing the section method is as follows: chisel the building surface layer and protective layer of the original concrete column, add longitudinal stress steel bars and circumferential stirrups on its periphery, and pour concrete to form a core column with the original concrete column ...
