Above-mentioned common brick can be perforation common brick.The thickness of perforation common brick is preferably the monolithic clay brick of 60mm, this kind of monolithic pottery Cob brick increases high molecular reactive charcoal in sintering procedure, increases intensity, not only environmental protection but also can ensure that its load-bearing capacity in this way.This
In, clay brick refers to using stone using natural clay as main component using tonerde even violet sand earthenware clay high-temperature firing English, feldspar etc. are aggregate, and the civil engineering formed after oversintering is built a wall.Clay brick has the advantage that:1, excellent freeze thawing resistance is special Property, i.e., in the case where water absorption rate reaches 10%, Imitation Rock Porcelain Tiles freeze thawing whole bursting by freezing three times at -15 DEG C, and earthenware brick can With in the environment of -45 DEG C freeze thawing there is not slight crack 50 times.2, there is good anti-light pollutant performance:Earthenware brick can by 90% with On light all reflect, to protection human body eyesight, reduce light pollution have good effect.3, there is good sound absorption, by In earthenware brick entire body rich in a large amount of uniform fine and closely woven open stomatas, therefore sound wave can completely or partially be reflected away, play outdoor Reduce noise, the effect of indoor elimination echo.4, good gas permeability, water penetration.5, there is good weather resistance corrosion resistance.
In order to realize that pendant and the installation of common brick layer are connect, silk cylinder can be set as a kind of preferred embodiment, silk cylinder can be plating Zinc hexagonal silk cylinder.The dimensions of zinc-plated hexagonal silk cylinder 3 is 140mm (internal diameter) × 400mm (length).It is, of course, also possible to using Bolt part carries out installing fixed
(4), paste common brick layer:Before common brick installation, alkali prevention inorganic agent, the alkali prevention inorganic agent are coated at its back side and side For organic silicon coating, while in common brick bottom brushing resin glue, then chemical fiber wire grid cloth is pasted, forms tension waterproof layer;
(5), whitewash:Whitewashing for putty is carried out on the outside of mounted common brick layer, it is 1-1.2mm to whitewash thickness;
(6), prevention processing:It is scrubbed with 10% oxalic acid solution on the metope after whitewashing, after washing, uses clear water Rinse, after abundant drying, sprayed with solidification waterproofing agent, the solidification waterproofing agent for NC304S nanoscales curing agent or NC304W waterproofing agents, the spraying method for curing waterproofing agent are:Solidification waterproofing agent first pass brushing is carried out, is carried out after conjunctiva Second time brushing carries out third all over brushing after conjunctiva again, carries out the 4th time brushing after conjunctiva again, until it is thick to obtain spraying Degree requires, coating thickness 0.8-1mm.
The present invention operation principle be:Alkali prevention inorganic agent is applied in back face of stone and the side back of the body before slabstone installation, which will It penetrates into common brick layer and blocks capillary, make water, Ca(OH)2, other substances such as salt can not invade, and cut off the approach of accumulation of salt in the surface soil phenomenon. Without painting processing is carried on the back, the accumulation of salt in the surface soil is inevitable, and the cementability that the common brick layer of processing is applied through the back of the body is unaffected, while using and containing water-reducing agent Mortar, be further reduced Ca(OH)2 precipitation, in addition, by whole building wall surface design at dried hanging hang structure so that in mortar The moisture contained will not directly penetrate into common brick layer, reduce the formation of the accumulation of salt in the surface soil, prevented from source, and construction terminates Afterwards, prevention processing is carried out, by spraying oxalic acid solution and solidification waterproofing agent, further suppresses the generation of accumulation of salt in the surface soil phenomenon, simultaneously Easy to operate, reliability is high, highly practical, is worthy to be popularized.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power Profit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent requirements of the claims Variation is included within the present invention.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art The other embodiment being appreciated that.
