Problems solved by technology
The production and molding process of foam concrete includes the installation of light steel keel, the installation of cement fiber board and the pouring of foam concrete. After the pouring is formed, the crack prevention treatment of the slab joints is carried out, and then the decorative layer construction is carried out. However, the slab joints will crack in the later stage. The repair after the seam is cracked becomes the most important thing during the warranty period. In order to reduce the maintenance cost and improve the success rate of the seam repair, the present invention proposes a method for repairing the seam of the foam concrete light steel keel composite wall

Embodiment Construction
[0017] The present invention is described in further detail below, so that those skilled in the art can understand more clearly, foam concrete light steel keel composite wall slab seam repairing method of the present invention adopts following scheme, comprises the following steps:
[0018] (1) Grind the cracks of the wall until the cracks disappear, and then clean up the grinding debris and floating dust on the grinding parts;
[0019] (2) With the board seam as the center, evenly apply the first layer of white latex with a width of 120mm;
[0020] (3) Take the board seam as the center, paste a layer of seam cloth bandage on the first layer of white latex, and then compact the seam cloth bandage;
[0021] (4) Spread the second layer of white latex evenly on the seam cloth bandage and 10mm around the seam cloth bandage, and let it stand naturally for 48 hours;
[0022] (5) Scrape putty powder on the polished part to form a putty powder layer, and then place it naturally for 4...

The invention discloses a method for repairing board joints of a foamed concrete light steel keel composite wall. The method for repairing the board joints comprises the following steps of grinding awall crack until the crack disappears, and then cleaning the wall completely; with the board joints as the center, evenly coating the wall with a layer of white latex; with the board joints as the center, attaching and compacting a layer of joint cloth bandage to the first layer of white latex; evenly coating the joint cloth bandage and the portion, within the range of 10 mm, of the periphery of the joint cloth bandage with a second layer of white latex; plastering the grinding part with putty powder to form a putty powder layer; grinding the putty powder until the surface is flat, and then cleaning the surface of the putty powder layer completely; spraying latex paint onto the surface of the putty powder layer. By means of the method for repairing the board joints of the foamed concrete light steel keel composite wall, various kinds of wall board joints can be repaired, the operation is simple and convenient, the success rate of maintaining the board joints can reach 99%, the repairing effect is good, repeated repairing is avoided, the maintenance cost is reduced accordingly, and the re-cracking probability of the repaired wall is low.
Description
technical field [0001] The invention relates to the technical field of construction, and relates to a method for repairing cracks in foam concrete light steel keel composite walls. Background technique [0002] Foamed concrete adopts physical foaming technology, and then adds foam to the slurry made of cement, aggregate, admixture, admixture and water, etc., and casts it on site. It has light weight, heat preservation, good overall performance, It has excellent performances such as earthquake resistance and environmental protection, and can be nailed and slotted. It is convenient for construction and environmentally friendly, and can reduce construction costs. The production and molding process of foam concrete includes the installation of light steel keel, the installation of cement fiber board and the pouring of foam concrete. After the pouring is formed, the crack prevention treatment of the slab joints is carried out, and then the decorative layer construction is carried...
