Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a carbon fiber cloth pasting and reinforcing device for building surfaces. Background Art

[0002] The traditional construction process of external carbon fiber cloth reinforcement of concrete structure is: base surface treatment, base surface cleaning, brushing structural adhesive, pasting surface repair, pasting carbon fiber cloth, maintenance, and surface protection treatment. The key processes include: carefully grinding the deteriorated layer (such as floating slurry, weathering layer, etc.) of the concrete pasting surface with a grinding wheel; wiping the surface with acetone or anhydrous alcohol; evenly applying structural adhesive with a roller or brush, etc. During the construction of the carbon fiber cloth, it is necessary to roll its surface with a roller continuously to make the carbon fiber cloth and resin fully saturated, and ensure that there are no bubbles on the surface of the carbon fiber cloth. When the carbon fiber cloth is fixed, the two ends of the carbon fiber cloth are compacted, resulting in a thin adhesive layer on both sides and thick in the middle, and the roller cannot act on the entire carbon fiber cloth surface when rolling, but can only act on one line. After rolling, it is easy to relax, and the carbon fiber cloth is easy to slip and then drive the structural adhesive to slip, resulting in uneven adhesive layer thickness, which reduces the effect of carbon fiber cloth reinforcement of concrete. Therefore, in the reinforcement of carbon fiber cloth, uneven distribution of structural adhesive and uncontrollable adhesive layer thickness have become difficult problems in construction quality control.
