If reference is made to "first" or "second", this should be understood to distinguish between features and not to indicate or imply relative importance or to implicitly indicate the number of indicated features or to implicitly indicate the precedence of the indicated features.
Referring to fig. 1, a structural schematic view of a crack-resistant plastered wall body according to an embodiment of the utility model is shown. The crack-resistant plastering wall sequentially comprises a wall body 100, an interface coating 101, separating strips 102, a plastering layer 103, a first putty layer 104, a reinforcing layer 105 and a second putty layer 106, wherein the separating strips 102 are strip-shaped, a plurality of separating strips 102 are spliced on the interface coating 101 to form a grid shape, and the plastering layer 103 is filled in the grid formed by the separating strips 102. After the wall 100 base surface is cleaned, the interface coating 101 is formed by painting I-type or II-type concrete interface treating agent, and if the temperature is higher or the wall surface is dry, the wall 100 base surface can be properly watered and moistened before the interface coating 101 is painted.
For the division bar 102, the interval between the vertical and horizontal arrangement is 0.8 m-1.2 m. The horizontal and vertical arrangement intervals of the division bars 102 are less than 0.8m, the construction material cost and the labor cost are both high, the arrangement intervals are more than 1.2m, and the compensation effect of the division bars 102 is not ideal. Before division bar 102 construction, earlier with the level and smooth perpendicular degree of holding in the palm line board inspection wall, confirm the thickness of plastering in view of the above, the thinnest department of wall plaster thickness should not be less than 7 mm, during the division bar 102 construction, after the wall has been brushed interface coating 101, set up horizontal division bar 102 at wall body bottom and top, the middle part region sets up vertical division bar 102, and its setting principle is: the bottom and top transverse parting strips 102 are spaced from the internal and external corners by a distance of no more than 300mm and the skirting line or the top opening line of the skirting is located in the region of the bottom transverse parting strip 102. The separator strip 102 may be implemented by means including, but not limited to, factory machining. By arranging the partition strips 102, after the construction of the anti-crack plastering wall is finished, the cracking of the plastering wall surface is effectively reduced and prevented, and the service life of the wall body can be prolonged.
Referring to fig. 2, the combination of the partition strips 102 and the plastering layer 103 can divide the large-area plastering layer 103 into a plurality of smaller areas, so that the plastering layer is uniformly stressed, and meanwhile, the partition strips 102 made of micro-expansion cement mortar can compensate the shrinkage of the plastering wall surface and establish certain self-stress by utilizing the characteristic that the partition strips generate volume expansion in the hydration and hardening processes, thereby solving the adverse effect caused by shrinkage. For the plastering layer 103, after the partition strip 102 made on the construction site is slightly dry, the plastering layer 103 can be plastered. The plastering layer 103 is applied layer by layer to avoid cracking caused by inconsistent internal and external shrinkage of the plastering mortar due to thick thickness of one-time application. Generally, when plastering mortar is coated, the thickness of each time is preferably 5-7 mm; when the mortar is layered and smeared, the condition that the internal structure of the smeared mortar is damaged to influence the bonding with the previous layer when the mortar is smeared on the next layer is prevented, the condition that the shrinkage rate is overlarge due to the fact that a plurality of layers of wet mortar are combined together to cause the cracking and hollowing of the plastering layer 103 is avoided, the cement mortar is smeared on the next layer after the previous layer of plastering layer is condensed, the cement mortar is sprayed with water for curing after being plastered for 24 hours, and the curing time is not less than 7 days
For the reinforcing layer 105, the material of the reinforcing layer 105 is alkali-resistant glass fiber cloth, and the mesh size of the alkali-resistant glass fiber cloth is 0.5 mm-10 mm. The alkali-resistant glass fiber mesh fabric is in a mesh shape woven by glass fibers added with glue, has strong tensile and alkali resistance, has strong adhesion with mortar, and can be combined with the mortar into a united body. Because the alkali-resistant glass fiber mesh cloth is arranged in the plastering layer 103, the plastering mortar and the alkali-resistant glass fiber mesh cloth act together, the tensile strength of the plastering layer 103 is improved, and the plastering layer is not easy to crack. The mesh size of the alkali-resistant glass fiber cloth is 0.5 mm-10 mm, so that the requirement on the use strength of the alkali-resistant glass fiber cloth as a reinforcing mesh of the anti-cracking wall body can be met, and the construction cost cannot be increased.
For the first putty layer 104, in the construction process, in order to avoid the first putty layer 104 from being too large in shrinkage and cracking and falling off, one-time blade coating is not too thick, the thickness of the first putty layer 104 is preferably about 2mm, and the blade coating is finished in 2-3 times. After the first putty layer 104 is uniformly smeared on the plastering layer 103, the alkali-resistant glass fiber cloth is pressed in, and a proper amount of putty is supplemented and smeared on the part of the alkali-resistant glass fiber cloth which is not pressed in the first putty layer 104. During construction of the alkali-resistant glass fiber cloth of the reinforcing layer 105, folding is strictly forbidden, and the edge of the gridding cloth and overlong rough edges are cut off. And after the alkali-resistant glass fiber cloth is pressed into the first putty layer 104 and dried for 1 to 2 days, constructing a second putty layer 106. For the second putty layer 106, the putty is fully applied vertically by using a rubber scraper, and the construction method is the same as that of the first putty layer 104, so that the line and the foot are straight and square. After the putty is dried, the putty is polished by fine sand paper until no sand grains appear. The surface after being polished is smooth, the internal and external corners are straight, no cracks, broken corners and sand holes are generated, and no obvious concave-convex scratch marks and rough feeling are generated. The wall surface must be thoroughly cleaned once after polishing so as to prevent the adhesion of the coating from being affected by too much dust.
