Abstract
The invention relates to a hollowing-preventive concrete base layer plastering method which is characterized by comprising steps of preparing plaster and plastering tools and reagents for construction preparation; treating concrete surfaces, to be more specific, wetting the concrete surfaces by the aid of water and flushing away impurities such as dust on the concrete surfaces; blending interface agents by the aid of water to obtain paste, sufficiently and uniformly stirring the paste, allowing the paste to stand still for 5-10 min to allow the interface agents to be thickened, adding water into the interface agents and uniformly stirring the interface agents for standby application; attaching the uniformly stirred interface agents onto the concrete base layers by the aid of smearing processes or spraying processes and starting to plaster the concrete base layers after the interface agents are solidified. The blended interface agents need to be used up in 5-6 hours. The hollowing-preventive concrete base layer plastering method has the advantages that each concrete base layer is plastered after a layer of interface agents is attached onto the concrete base layer by the aid of the smearing processes or the spraying processes, and accordingly hollowing generated when existing concrete base layers are directly plastered can be prevented.
Description
Technical field
A kind of the present invention relates to the realm of building construction, in particular it relates to concrete base layer plastering method for avoiding hollowing from producing.
Background technology
In construction, it is a kind of indispensable construction procedure that mixed mud is poured, construction for building frame formula structure has irreplaceable effect, and during mixed mud is poured, reinforcing bar is to build mixed mud framework framing structure, thus the collocation of mixed mud and reinforcing bar becomes the necessarily combination of building trade, the mechanical requirements of building not only can be met, and resistant to corrosion, under the passage of time, the structural stability built will not be caused to be deteriorated by wind and frost sleet corrosion.
Mixed mud is also referred to as concrete, abbreviation concrete, refers to the general designation of the integral engineered composite material that gathers materials by Binder Materials.The concrete generally said to be referred to and do Binder Materials with cement, and sand, masonry gather materials, and coordinates by definite proportion row with water, and cement concrete obtained by agitated, molding, maintenance, also referred to as normal concrete are widely used in civil engineering.
In the case where concrete surface is more smooth, coat of plaster is also easy to produce hollowing, and hollowing is referred to due to having what air caused in former masonry and powder grieshoch.The generation of hollowing influences whether the quality that concrete is plastered, thus should avoid the generation of hollowing during plastering as far as possible.
The content of the invention
The technical problem to be solved is to provide a kind of concrete base layer plastering method for avoiding hollowing from producing, to overcome existing concrete coat of plaster to be also easy to produce the problem of hollowing.
The present invention the adopted technical scheme that solves the above problems is：A kind of concrete base layer plastering method for avoiding hollowing from producing, comprises the following steps：
（1）Preparation of construction：Get out instrument, the reagent plastered and plaster；
（2）The surface treatment of concrete：By the water-wet of mixed mud surface, the impurity such as the dust of concrete surface are washed away；
（3）Interfacial agents water is tuned into into pasty state, is stirred, place 5～10min, interfacial agents meeting retrogradation now adds water and stirs, and stand-by, the interfacial agents allocated should be finished at 5～6 hours；
（4）The interfacial agents for stirring are attached on concrete base layer with semar technique or spray hair method；
（5）Plastered after interfacial agents solidification.
In the case where concrete surface is more smooth, coat of plaster is also easy to produce hollowing, the generation of hollowing influences whether the quality that concrete is plastered, thus the generation of hollowing should be avoided during plastering as far as possible, the present invention is being plastered after adhering to a bed boundary agent on concrete base layer using semar technique or spray hair method, the hollowing produced when directly plastering on concrete base layer is avoided thus, instant invention overcomes existing concrete coat of plaster is also easy to produce the problem of hollowing.
Further, semar technique refers to the interfacial agents full coat that will be stirred on basic unit face, 2～3mm of thickness, after 10～20min, smears cement mortar screeding layer, repeatedly thin to smear screed-coat.Using smearing, power consumption is relatively low, is conducive to cost-effective.
Further, it is the interfacial agents for mixing up uniformly to be ejected on concrete base layer using air pump to spray hair method, and nozzle diameter used is 5mm, and from metope 0.5m during injection, 0.7～0.8Mpa of air pressure, spray hair carried out scraping rough screed-coat to metope after 2 hours.Spray hair method has jet velocity and jet quality faster.
Further, when interfacial agents are tuned into pasty state, water is 1 with the weight ratio of interfacial agents:4.This than row can quickly by interfacial agents mix with water and be deployed into pasty state and be unlikely to so that interfacial agents concentration it is too low.
Further, interfacial agents of the interfacial agents using powder.Powder is conducive to the quick dissolving of interfacial agents.
To sum up, the invention has the beneficial effects as follows：
1st, the present invention is being plastered after adhering to a bed boundary agent on concrete base layer using semar technique or spray hair method, it is to avoid the hollowing produced when directly plastering on concrete base layer.
2nd, the nozzle diameter of present invention spray hair method is 5mm, and from metope 0.5m during injection, 0.7～0.8Mpa of air pressure, with jet velocity faster and jet quality.
