The construction method for the pulverized low-strength base layer wall surface strengthening treatment structure is characterized in that the method comprises the steps that (1) a wall base layer is treated, and the tensile adhesive strength of the treated base layer wall is increased to 0.5-0.7MPa; (2) roller coating is carried out on the base layer wall by using a roller on a boundary layer; (3) a protective coating is added on the basis of the step (2). The construction method is applied to the surface of the pulverized low-strength base layer wall.
Description
Technical field:
The present invention relates to the construction method of a kind of efflorescence, low-intensity base course wall surface enhancing processing structure.
Background technology:
In the concrete practice of building operations, along with the commercialization of basic unit's motar, when base course wall plastering construction, generally adopt commodity dry powder and mortar.But along with the competition of commodity mortar is more and more fierce, profit margin is more and more lower, commodity mortar quality worse and worse, extra material volume also more gradually strengthen, cause in intensity slower, if the bad intensity of maintenance cannot be come up at all, or in order to save cost, in practical engineering application, tend to use defective dry-mix or Site mortar, cause base course wall floated coat not reach acceptance criteria, occur the problems such as efflorescence, intensity be low.
Efflorescence, low-intensity foundation base intension in actual engineering, often out in the cold no matter or fallen replastering by shovel, will in construction in later period, run into a series of problems such as come off as out in the cold; Again shoveled to fall to do over again, will be affected the duration, caused resource huge waste.
In order not affect to the full extent programming, do not waste too many resource, ensure the quality of products again, must process basic unit, stop later stage safety, hidden danger of quality.
The present body of wall basic unit with common interior exterior wall cement plastering mortar plaster leveling, its tensile bond strength≤0.20MPa, intensity is low, quality does not pass a test.
Summary of the invention:
The object of this invention is to provide a kind of intensity efflorescence, low-intensity base course wall surface high, that do not need to do over again, improved construction quality and strengthen the construction method of processing structure.
Above-mentioned object realizes by following technical scheme:
Efflorescence, low-intensity base course wall surface strengthen a construction method of processing structure, and this method comprises three steps, and the first step is processed body of wall basic unit, makes base course wall tensile bond strength be increased to 0.5-0.7MPa after processing; Second step is in cylinder roller coating roller coating on base course wall for boundary layer; The 3rd step increases overcoat on the basis of second step.
Described efflorescence, low-intensity base course wall surface strengthen the construction method of processing structure, it is construction wall basic unit that the described first step is processed body of wall basic unit, suck and float ash, impurity and loosening efflorescence dust with dust catcher, then water sprays one time, then dry 24h.
Described efflorescence, low-intensity base course wall surface strengthen the construction method of processing structure, described second step is to add water to add water to become liquid surface agent with the dilution proportion of 1: 1 with liquid surface agent or the self film building emulsion of the dilution proportion of 1: 1 osmosis type building emulsion at boundary layer with cylinder roller coating on base course wall, with cylinder base course wall roller coating 2 times, more than twice roller coating time interval 4h.
Described efflorescence, low-intensity base course wall surface strengthen the construction method of processing structure, the 3rd described step on the basis of second step, increase overcoat be complete at second step base course wall on scrape the about 2mm of anticracking grout thickness one time, and then the alkaline-resisting grid cloth that is 160g/m2 mass area ratio is pressed into, criticize again and scrape the about 2mm of one deck anticracking grout thickness, and then the alkaline-resisting grid cloth that is 160g/m2 one deck mass area ratio is pressed into, criticize the mortar of scraping the about 1mm of a layer thickness, under natural conditions, maintenance is more than 3 days again.
Beneficial effect:
1. the invention solves that efflorescence in existing engineering, base course wall intensity are low, poor stability, later stage hidden danger are many, greatly affect programming, greatly waste the problems such as resource, can make base course wall tensile bond strength be increased to 0.5-0.7MPa.
No matter 2. the invention solves efflorescence, low-intensity base course wall cannot be processed or problem out in the cold, solve the problem that affects programming, solve the problem of the wasting of resources, solved the problem of efflorescence, low-intensity base course wall intensity difference, guaranteed workmanship.
3. the present invention does not need to shovel the processing of falling to do over again, on-site construction time is short, and curing time is short, and construction technology is simple, can make base course wall tensile bond strength be increased to 0.5-0.7MPa, the base course wall tensile bond strength≤0.20MPa producing higher than existing construction method far away.
4. the present invention has also thoroughly solved the many problems of later stage potential safety hazard, has guaranteed construction quality, has guaranteed construction speed.
