Embodiment

[0012] 1. Surface treatment: remove the laitance, oil, and impurities on the concrete surface of the pasting part. If there are honeycombs and cracks on the surface, they should be repaired to expose the structure body, blow it off, and wipe it with acetone. Wipe off the floating ash on the surface with carbon fiber material. 2. Brushing the primer: apply the primer that has been fully mixed in proportion to the concrete surface evenly. 3. Repair and leveling: After the above process, if there is any unevenness on the concrete surface, use repair glue to level it. 4. Glue preparation: Prepare the adhesive glue according to the weighing ratio, stir the groups A and B separately before mixing, and then fully stir after mixing. 5. Paste carbon fiber: cut the present invention according to the size required by the design, and apply the prepared adhesive evenly on the concrete surface of the pasted part. On the basis of coating the adhesive glue, the cut-out invention is rolle...

Abstract

The invention belongs to the field of construction repair and reinforcement, and particularly relates to a carbon fiber prepreg fabric for repairing and reinforcing a structure. The carbon fiber prepreg fabric comprises an insulation protection layer and a carbon fiber prepreg weaving layer, wherein the carbon fiber prepreg weaving layer comprises a longitude line and a latitude line, the longitude line is formed by unidirectional pre-impregnated carbon fiber bundle lines, the latitude line is formed by hot melting lines, and the hot melt lines are fixed together with the pre-impregnated carbon fiber bundle lines through heating. The carbon fiber prepreg fabric is convenient to construct, free of large equipment, free of wet operation, free of dynamic fire, free of on-site fixing facilities, small in construction occupied site and high in construction work efficiency. Meanwhile, the abrasion-resistant insulation protection layer protects the carbon fiber prepreg braided layer from being damaged and plays an insulating protection role, the durability is higher, the maintenance period is longer, the hot melting lines are arranged in a single-shape arrangement, the hot melting lines which are arranged in parallel are firmer, and the strength of the fabric is improved.

Description

technical field [0001] The invention belongs to the field of structure repair and reinforcement, and in particular relates to a carbon fiber prepreg fabric for structure repair and reinforcement. Background technique [0002] With the aging of urban infrastructure, the continuous occurrence of natural disasters such as large-scale earthquakes, and the emergence of other problems, people have gradually improved their understanding of the repair and reinforcement of structures. Or thickened concrete and other construction methods. Carbon fiber cloth reinforcement is a relatively new reinforcement method that uses fiber reinforced materials to paste masonry structures. The function is that fiber materials bear tensile stress in the reinforced structure, improve the stress state of components, and limit the occurrence and development of cracks. The advantages are high strength, low density, thin thickness, and basically no increase in the self-weight and cross-sectional size of...
