Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a carbon fiber cloth pasting and accelerated maintenance device for structural reinforcement. 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: 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 a brush, etc. In the construction process of pasting carbon fiber cloth, it is necessary to roll the 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. The roller cannot act on one 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, thereby driving the structural adhesive to slip, which in turn causes uneven adhesive layer thickness and reduces the reinforcement effect of the component. Therefore, in the reinforcement of carbon fiber cloth, uneven distribution of structural adhesive and uncontrollable adhesive layer thickness become a difficult problem for construction quality control. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a carbon fiber cloth pasting and accelerated curing device for structural reinforcement, which can not only ensure the integrity of the adhesive layer construction and achieve the effect of consistent adhesive layer thickness, but also achieve the purpose of accelerated curing and shortening the construction period.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] As a further improvement of the above technical solution:

[0007] The external trough formwork is connected to the bottom of the concrete structure body through a detachable connecting structure, and the detachable connecting structure includes upper connecting pieces arranged on both sides of the concrete structure body, and lower connecting pieces arranged on both sides of the trough profile. Bolts pass through the upper connecting pieces and the lower connecting pieces and are connected to nuts to fix the external trough formwork to the concrete structure body.

[0008] The upper connecting member has a first vertical connecting plate and a first transverse connecting plate, and the lower connecting member has a second vertical connecting plate and a second transverse connecting plate, the first vertical connecting plate is in abutment contact with the concrete structure body, the second vertical connecting plate is in abutment contact with the trough profile, and the first transverse connecting plate is in abutment contact with the second transverse connecting plate.

The partition is arranged in the groove profile, so that the internal space of the groove profile is divided into an upper space and a lower space.

The groove profile is installed to the bottom of the concrete structure body and connected and fixed in a detachable manner, so that the carbon fiber cloth is pasted to the bottom of the concrete structure body.
