Concrete frame appearance quality defect repairing method

Abstract

The invention discloses a method for repairing appearance quality defects of a concrete frame, which is characterized in that different treatment schemes are made according to various defects of the concrete appearance, color difference of a construction forming part is avoided by combining the optimal proportion of a field construction environment test coating, and technical innovation is carried out in the aspects of base layer treatment, coating proportion, later maintenance and the like. Compared with a conventional repairing technology, the novel method is wider in repairing area, more attractive in appearance forming, shorter in coating solidification time, more durable in quality and longer in maintenance time, the probability of problems in the maintenance process is reduced, outdoor engineering construction can be better met, economic benefits are improved, and the novel method is worthy of popularization.

Description

technical field [0001] The invention belongs to the field of repairing appearance quality defects of reinforced concrete, and in particular relates to a method for repairing appearance quality defects of concrete frames. Background technique [0002] The current concrete frame plus steel structure truss, due to the quality of commercial concrete raw materials, formwork leveling and cleanliness, and the technical level of construction personnel during the construction process, there is a high probability of common defects in the appearance of concrete components after formwork removal, usually including honeycomb, pitting, Holes, etc., serious and even lead to missing reinforcement, will affect the service life of the concrete structure, the conventional repair method of concrete appearance defects can only be repaired in a small area, and after the construction is completed, there is a color difference between the repaired part and the original concrete part, which affects th...

[0002]The current concrete frame plus steel structure truss, due to the quality of commercial concrete raw materials, formwork leveling and cleanliness, and the technical level of construction personnel during the construction process, after the concrete components are demolished There is a high probability of common defects in appearance quality, usually including honeycomb, pockmarks, holes, etc., which may even cause leaks in serious cases, which will affect the service life of concrete structures. Conventional methods for repairing appearance defects in concrete can only be repaired in a small area, and After the construction is completed, there is a color difference between the repaired part and the original concrete part, which affects the perception effect. In addition, conventional concrete repair materials are greatly affected by the external environment, and quality problems are prone to occur during subsequent maintenance and use. The overall quality cannot be guaranteed for a long time. Therefore, it is necessary to develop a new type of fair-faced concrete appearance repair technology, aiming at repairing the appearance quality defects of concrete frames, and providing technical guidance for subsequent construction of similar projects
