Problems solved by technology

However, there is a big problem with this repair method. Cracks will inevitably lead to damage to the structure of the balcony. Just repairing the cracks cannot completely bond the walls on both sides of the cracks. The damaged structure has not been repaired. Sometimes The filled concrete and the walls on both sides of the crack even have the problem of not bonding, so there is a big safety problem

Embodiment Construction

[0023] When cracks appear on the balcony, chemical pressure grouting should be performed on the cracks and then sealed with carbon fiber cloth. The main construction process is as follows:

[0024] 1. Chemical pressure grouting

[0025] The process includes: burying the grouting nozzle - sealing the seam - pressure testing - matching oars - grouting.

[0026] 1) Embed grouting nozzles: For cracks larger than 0.5mm, paste grouting nozzles at the intersections, wider parts and penetrations of cracks. When the gap width is less than 1mm, the distance between grouting nozzles is 350-500mm. When the gap width is greater than 1mm, the grouting nozzles The spacing is 500-1000mm. There must be a grouting nozzle, an exhaust nozzle, and a slurry nozzle at a crack. When burying, first apply a layer of epoxy cement of about 1mm on the chassis of the grouting nozzle to fix the grouting hole of the grouting nozzle at the predetermined position.

[0027] 2) Seam sealing: first apply a lay...

Abstract

The invention relates to a balcony crack reinforcing method, consisting of a chemical pressurized grouting stage and a carbon fiber obturation stage, wherein the chemical pressurized grouting stage consists of the following processes: grouting nozzle embedding, crack obturating, pressure testing, pulp preparation, and grouting; the carbon fiber obturation stage consists of the following processes: substrate processing, adhesive coating, leveling, and carbon fiber attaching. After the above-mentioned processes, the balcony cracks are strengthened well. The balcony crack reinforcing method of the invention is capable of completely mending the cracks of balconies, restoring the rigidity of the balcony wall to almost the original level, thereby ensuring safety effectively.

Description

technical field [0001] The invention relates to a construction technology, in particular to a reinforcement measure for cracks in balconies of buildings. Background technique [0002] Now people in the city basically live in commercial housing. In order to save land and improve the utilization rate of land, commercial houses are generally multi-storey or high-rise buildings. Commercial houses generally have balconies, which can not only provide a place to enjoy the scenery outside the house, but also provide people with a space to dry clothes, making people's lives more convenient. The balconies are all extended to the outside of the main body of the house through the reinforced concrete structure. From the outside, it seems to be suspended in the air. Since it is located outside the main body of the house, in order to reduce the weight, its structure cannot be too thick, or because of external factors, it is prone to the problem of cracks on the balcony. Cracks on the ba...
