Problems solved by technology

However, this reinforcement method has high requirements on the performance of the bonding material, and strict requirements on the size and process of the groove (the groove width is not less than 3 times the thickness of the reinforcement material), and the bonding and anchoring quality between the CFRP sheet and the concrete cannot be effectively guaranteed. , it is easy to produce peeling damage at the concrete groove interface after loading

Abstract

The invention belongs to the technical field of civil engineering. A flexural reinforcing structure for a concrete beam is arranged in a beam body of the concrete beam, and comprises a first caulkinggroove, second caulking grooves and anchors fixedly arranged in the second caulking grooves, wherein the first caulking groove is formed in one side face of the beam body; the second caulking groovesare formed in the first caulking groove at an interval; a reinforcing strip is cooperatively embedded in the first caulking groove; the reinforcing strip is cooperatively and fixedly clamped between the anchors, and the reinforcing strip is supported in the caulking groove of the beam body through the anchors. The invention also discloses a flexural reinforcing method for the concrete beam. The flexural reinforcing structure and method for the concrete beam have the advantages that the structural design is reasonable, the stability is good, the durability and operability of the product can begreatly improved, the reinforcement effect is optimized, and the bearing capacity of the reinforced concrete beam is improved.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a bending-resistant reinforcement structure and method of a concrete beam. Background technique [0002] In recent years, with the continuous improvement of the manufacturing process of carbon fiber materials, the cost of carbon fiber plate reinforcement projects has been greatly reduced. Based on its light weight and high strength material properties, it has been widely used in the field of reinforcement. At present, the most commonly used methods are the external paste method and the embedded method. Among them, the externally attached CFRP sheet reinforcement technology is relatively mature now, and most of the industry standards and specifications for structural reinforcement technology are promulgated for this technology, which is currently the most commonly used carbon fiber reinforcement method in actual projects. However, the method of externally pa...
