Embodiment

[0026] This embodiment: as figure 1 As shown, a carbon fiber structure reinforcement method, the method includes using a special structural glue to paste the carbon fiber cloth on the structure to be reinforced.

[0027] Before pasting the carbon fiber cloth, pre-soak the carbon fiber cloth with epoxy resin solution S1.

[0028] Paste the soaked carbon fiber cloth on the concrete crack surface S2 with epoxy resin adhesive.

[0029] The carbon fiber cloth is pasted along the direction of tension or perpendicular to the crack direction.

[0030] Since a carbon fiber structure reinforcement method is adopted, the method includes pasting the carbon fiber cloth on the structure to be reinforced with a special structural adhesive, pre-soaking the carbon fiber cloth with an epoxy resin solution before pasting the carbon fiber cloth, and soaking the carbon fiber cloth The cloth is pasted on the concrete crack surface with epoxy resin adhesive, and the carbon fiber cloth is pasted a...

Abstract

The invention belongs to the technical field of structural damage detection and reinforcement, and particularly relates to a carbon fiber structure reinforcement method. Before pasting a carbon fibercloth, the carbon fiber cloth is pre-soaked with an epoxy resin solution, the carbon fiber cloth after immersion is pasted on the surface of a concrete crack with an epoxy resin adhesive, and the carbon fiber cloth is pasted in the direction of the tension or in the direction perpendicular to the cracks. The carbon fiber structure reinforcement method solves the problem that in the prior art, thestrength, rigidity, stability and durability of a structure and a member cannot be well improved in the prior art, and has the beneficial technical effects of improving the strength, rigidity, crack resistance and elongation of the structure and being good in anti-seismic effect and better in reinforcement effect.

Description

technical field [0001] The invention belongs to the technical field of structure damage detection and reinforcement, and in particular relates to a carbon fiber structure reinforcement method. Background technique [0002] At present, the widely used methods for structural damage detection and reinforcement are mainly artificial neural network technology based on neural network, in addition to the use of genetic algorithm for structural damage diagnosis research, etc. The basic method of neural network for damage identification is: according to the structure Corresponding to different damage degrees of different damage parts in different states, through feature extraction, select parameters that are more sensitive to structural damage as the input vector of the network, and the damage state of the structure as the output, establish a damage classification training sample set, and then train the network , after the training is completed, it is classified into the closest cate...
