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.

Application of CFRP material in wall strengthening

CFRP systems can be used for wall shearing and bending reinforcement, earthquake and explosion protection, damage repair, replacement of deteriorated steel, waterproofing, etc. Another common application of FRP is to strengthen areas around wall openings that may have to be created for doors and windows.

Application of CFRP material in slab and deck strengthening

FRP can be designed to increase the live load capacity of slabs or restore the original capacity reduced by corrosion of steel bars. According to the project conditions, FRP can be applied to the top or bottom surface of slab to achieve strengthening.
