Carbon fiber reinforcing method for concrete cracks

Abstract

The invention discloses a carbon fiber reinforcing method for concrete cracks. The carbon fiber reinforcing method comprises the steps that the concrete cracks with the crack width within the preset width are cleaned; adhering the edge of the first layer of carbon fiber cloth covering the concrete crack to the peripheral side of the concrete crack; and the outer side surface of the first layer of carbon fiber cloth is coated with an adhesive, and medium sand is sprayed. According to the carbon fiber reinforcing method for the concrete cracks, the concrete cracks of a concrete building are repaired and reinforced through the carbon fiber cloth, the carbon fiber cloth is high in strength, small in density, small in thickness and good in adhesion performance with the building, continuous cracking of the area where the concrete cracks are located can be limited, and the problem of continuous tearing of the concrete cracks is solved; and construction can be simplified, and easy connection with the subsequent construction process is achieved.

Description

technical field [0001] The present application relates to the field of building construction, and in particular, to a carbon fiber reinforcement method for concrete cracks. Background technique [0002] Structural cracks are prone to occur during the construction of concrete buildings. Such structural cracks not only affect the subsequent construction, but also seriously affect the structural strength and facility safety of concrete buildings. For this reason, glass fiber mesh and steel mesh are currently used to repair the aforementioned cracks. [0003] However, in the process of concrete surface construction, such as using glass fiber mesh and steel wire mesh to repair the cracks in the concrete surface, it is not only necessary to clean the existing structure of the concrete surface in a large area, but also it is difficult for the glass fiber mesh or steel mesh to be effective for a long time. Therefore, the repair effect is effective, and it is easy to cause quality p...

Problems solved by technology

[0003] However, in the construction process of the concrete surface, if glass fiber mesh or steel wire mesh is used to repair the cracks in the concrete surface, it is not only necessary to clean up the existing structure of the concrete surface in a large area, but also it is difficult for the glass fiber mesh or steel wire mesh to be effective for a long time. Prevent the cracks from continuing to crack, so the repair effect is effective, and it is easy to cause quality problems in concrete buildings
