Discussion on Carbon Fiber Wrap in Bridge Strengthening
Discussion on Carbon Fiber Wrap in Bridge t should be noted that carbon fiber reinforcement not only needs to pay attention to anchoring, but also needs to pay attention to the issue of dosage. First of all, the carbon fiber cloth has high strength, and excessive use will cause waste of materials. Secondly, the arbitrary use of carbon fiber cloth will reduce the ductility of concrete and affect the failure form of flexural members. The tensile failure of the carbon fiber cloth is transformed into sudden col

Construction method of carbon fiber wrap reinforced structure
The carbon fiber wrap is bonded to the surface of the concrete member with a high-performance epoxy-based adhesive, and the cement material is used as a shear connection medium between them to form a new composite body, so that the reinforcing patch and the original steel bar work together.

Analysis of reinforcement problems of prestressed carbon fiber p
A certain pre-stress is applied to the carbon fiber plate, and a certain strength is exerted in advance, so that the high-strength performance is fully utilized, which is an active reinforcement method, and the reinforcement effect on the structure is very obvious.

The substrate meets the requirements to ensure the effect
The mechanism of the planting method is to drill holes in the surface of the original structure, and then implant the steel bars after injecting the binder, so that the newly added structure and the original structure can be well combined into one whole and jointly stressed.

How to deal with the insufficient bearing capacity of beams
When the deflection of beam-slab structure members is too large, the crack width is too wide, too long, or the steel bar is seriously corroded, or the concrete in the compression area is crushed, reinforcement measures should be taken.

Carbon fiber wrap reinforcement in bridge reinforcement
For the reinforcement of bridge buildings, the use of carbon fiber wrap should first be immersed in epoxy resin to form strong sheet materials. Then the epoxy resin is bonded in the direction of cracks according to the direction of force. When the component is subjected to tension load, the crack will not be further cracked along the direction of force through the role of fiber sheets. Thus, it can reinforce the main body of the building and ensure the stability of the structure at the same time.

Stress characteristic and attention of CFRP reinforced bridges
Although CFRP is a soft cloth, it has brought new impetus to the development of civil engineering in recent years, especially in bridge reinforcement works, especially when the height is limited, its construction technology is relatively simple.
