Abstract
The invention relates to an anti crack method of decorative surfaces in inner and outer walls of artificial boards or frame boards and takes the steps that: the outer surface of a wall body is paved with a layer of sack paper, and a layer of wire net is paved on the outer side of the sack paper, that the wire net is fixed on the wall body through nails that is sleeved with paper gaskets; mixed mortar is smeared on the wire net, flattened and solidified into a decorative shell; and the outer surface of the decorative shell is decorated facially. The invention has the beneficial effects that: first, the mutual influence between the outer decorative material (such as cement mortar), the water, and wet and moisture air passages of the artificial wall, and the deformation of the two are separated; secondly, peeling and stratification are avoided because the connection between the separated two parts, the artificial wall and the outer decorative material has relatively larger stable strength; thirdly, slight cracks in the outer decorative material (such as cement mortar) are avoided; and fourthly, the cost is low and the construction technology is simple.
Description
(1) technical field
The present invention relates to the method that a kind of wood-based plate or frame plate external and internal wall control combination with decorative surfaces cracks, relate to all non-masonry building inside and outside wall bodies and build up the situation that the back combination with decorative surfaces cracks in the house, also be suitable for for waste residue masonry, cement block.
(2) background technology
Because worldwide energy shortage, the Chinese government proposes " energy-saving and emission-reduction " measure of implementing in building field, and prohibited and fired clay solid brick (part structural clay tile), people generally concentrate on notice on the light house that utilizes wood-based plate to do body of wall and the high-rise frame plate structure, but the coefficient of deformation of wood-based plate and the coefficient of deformation of ornament materials differ bigger, and the coefficient of deformation of the wood-based plate of various materials is also different.Thereby after body of wall is finished decoration, be subjected to climate change, and decorative material and wood-based plate deformation of wall are inconsistent, and influence each other, thereby crack at combination with decorative surfaces, the some months that has, and several days of having just produce.Crackle varies, and has destroyed the attractive in appearance of newly constructed house, and the serious thermal and insulating performance that also makes the house sharply descends, and house, a building is in perfectly good condition destroyed by big crackle.People's (comprising the building engineer) nearly all impute artificial plate quality to, and in fact except that steel plate (color steel sheet), all there is this problem in other wood-based plates.A tangible example is crackle not to take place or very little crackle takes place behind the general decoration of brick wall, uses the very fast generation of the numerous crackle of wood-based plate instead.
Find that after having contrasted brick wall and wood-based plate body of wall brick wall is very thick, every brick small-sized, and have mortar (loosening) to build by laying bricks or stones between brick and the brick, and before decoration, allow brick inhale " satisfying " water.Yet wood-based plate is very thin, and area is very big, can not spray water before decoration.When decorating outside body of wall thus, the water that is coated in the mortar on the brick wall body can not absorbed (or seldom absorbing) by brick, and the mortar aquation is complete, and intensity increases.Though when the exterior wall moisture absorption or the suction when loam brick permeates, also can cause loam brick micro-strain, mortar is cracked, promptly outer decoration mortar and brick wall are independent of each other, even fine cracks occurs, also be because the brick wall suction is insufficient, or the mortar prescription is inaccurate or work progress is not strict.Otherwise the wood-based plate body of wall is just different, before approaching, decorate, plate can not water (otherwise board wall is with gross distortion) to body of wall, when smearing the decorative layer mortar in the board wall outside thus, board wall (no matter being cement board, gypsum plank or resin plate) absorbs the water in the mortar immediately, lack of water can not aquation (or aquation is incomplete) causes mortar not have intensity or intensity is lower in the mortar, and wallboard after sucking moisture, take place wetly to rise, dry-shrinkage deformed, mortar is cracked.Crackle on the decorative layer mortar is subjected to ectocine again, dry air, moisture laden air and sleet are penetrated into again on the board wall by crackle, and board wall distortion is reflected on the decorative layer mortar again, so repeatedly and irregular following, crackle is increasing, particularly in the seam crossing maximum of plate and plate.
(3) summary of the invention
The method that the object of the present invention is to provide a kind of wood-based plate or frame plate external and internal wall control combination with decorative surfaces to crack, this method can be isolated body of wall and outer decorative layer mutually, body of wall firmly is connected with outer decorative layer, has thoroughly avoided outer decorative layer to crack.
The present invention realizes by following measure:
The method that wood-based plate of the present invention or frame plate wall control combination with decorative surfaces crack is characterized in that adopting following steps:
(1) one deck sack kraft paper is laid in the outside of body of wall, overlap mutually between the sack kraft paper, and plastic-coated of described sack kraft paper or bonding layer of plastic film, another side is a body paper, the one side of body paper is outwardly;
(2) outside lay one deck wire gauze of sack kraft paper is fixed on wire gauze on the body of wall with the screw that is with paper washer;
(3) mortar that mixes is coated on the wire gauze, floating, be solidified into decorative shell;
(4) carry out incrustation in the outside of decorative shell.
The method of the invention described above in order to improve the hot strength of mortar, prevents that screed from cracking, and is mixed with the string chip of weight 2%～10% in the described mortar, and the length of string chip is 1～9mm.
The method of the invention described above, described wire gauze is preferably galvanized wire mesh.The nonwoven that sack kraft paper also can use string (as waste cotton velvet, cotton) to make replaces.
The method of the invention described above, described wire gauze iron wire diameter 〉=1mm weaves into hexagon or quadrangle; Described screw diameter is 2.5～3mm, length 30～35mm.
The method of the invention described above, the thickness of described decorative shell is generally 10～15mm.
The present invention has mainly adopted following four key technologies:
First key technology: selected a kind of well-pressed, have the separation layer of the different paper of big tension stress intensity, two surface naturies as wood-based plate body of wall and mortar housing, this paper is the sack kraft paper of plastic-coated or coated film normally.Sack kraft paper is normally specialized in a kind of package paper with higher-strength of making the industrial packaging paper bag, is mainly used in packing, storage, the transportation of cement, chemical fertilizer, agricultural chemicals etc.In use because the needs of technology, the one side of paper is plastic-coated not, and this one side of paper and cement mortar are combined into the base plate of decorative shell with mortar, wire gauze in conjunction with well in the work progress.The another side plastic-coated of paper or compound with film, in order to stop the water (later stage is moisture laden air or sleet) in the mortar to be absorbed by the wood-based plate body of wall, guarantee that hydrated cementitious is complete in the mortar, and make the self-deformation of the self-deformation of wood-based plate body of wall or decorative shell not influenced mutually.The wood-based plate coefficient of deformation of plank and various materials differs greatly, and self does wet degree during installation and has a strong impact on the deformation of wall amount again, between it and the plastic-coated sack kraft paper relative motion is arranged, but does not influence the mortar housing.
Plastic-coated sack kraft paper can be common kraft or possess certain tensile strength and well-pressed paper with other, also can replace by a laminated film, film and common paper compound can mechanization be compound also can be compound by hand, but compound paper can not have gauffer.
The nonwoven that sack kraft paper also can use string (as waste cotton velvet, cotton) to make replaces.
Sack kraft paper is preceding at plastic-coated (or laminated film), and the main technical requirements of original paper should be:
1. tension stress: 〉=450N;
2. quality (i.e. " quantitatively "): 70～90 gram/m
2
3. well-pressed, nothing is fawned on.
Second key technology: sack kraft paper, galvanized wire mesh, the common decorative shell of forming of composite cement mortar (or other mortars), thickness is about 10～15mm; Galvanized wire mesh (other wire gauze also can) is linked to each other housing with paper washer by screw with the wood-based plate body of wall, with the gravity of housing and natural load (as wind carry, bump stroke etc.) be delivered on the wood-based plate body of wall.
Galvanized wire mesh: iron wire diameter d=1～1.2mm, weave into hexagon or quadrangle;
Screw: diameter d=2.5～3mm, length L=25～35mm;
Paper washer: generally by the ground paper punching, paper washer outer diameter D=10～16mm, gross thickness is determined by thickness of shell.
The 3rd key technology: added breaking bits, rice-straw fibre or other plant fiber in the mortar prescription, with the fine cracks that prevents that mortar drying (housing drying) back from producing, addition on the kind of fiber decide, usually between 2%～10% (weight ratio).Other compositions are identical with conventional decoration of exterior wall prescription with ratio in the mortar, do not have specific (special) requirements.
The 4th key technology: construction technology is more special.With the coated surface of sack kraft paper, fit with the wood-based plate body of wall earlier, the one side of plastic-coated is not outside, paper laterally, vertically all need overlap, the size of overlap joint is horizontal 5～10mm, vertical 3～5mm, cover with galvanized wire mesh again, galvanized wire mesh is fixed on the wood-based plate body of wall with screw and paper washer.Earlier on body of wall, bore the guide hole of d=1.2～1.6mm before fixing, will have the screw-driving (effect of screw is that the strength with shell body passes to body of wall by screw) of paper washer again, make equating at interval of sack kraft paper and galvanized wire mesh everywhere with electric drill.Pour into the mortar that has string again, flush, wire gauze is imbedded the architectural surface for the treatment of to brush again after mortar parches fully outer body of wall in the mortar with wire gauze.
More than listed key technology will guarantee that the external surface of artificial board wall body or various baking-free building blocks is decorated and crackle can not occur.Various wood-based plate exterior surface of wall crack with artifical board material and relationship between quality little, certainly the wood-based plate quality better, the quality of body of wall can be better, but directly do not influence the crackle of body of wall.
Creativeness of the present invention is that economical rationality, technology have solved the exterior decoration crack problem of long-term puzzlement building field, decoration industry simply.Crack problem has hindered the development that utilizes wood-based plate to build light body board house, has become the road blocking tiger of implementing " energy-saving and emission-reduction " in the building field.The approach that utilizes Ecological Building Materials (wherein main part is the wood-based plate that utilizes agricultural crop straw to make) build a house (particularly building solar house) has been opened up in the solution of this problem.
Method of the present invention has following beneficial effect: the first is cut off decorative material (as cement mortar) and the passage of wood-based plate body of wall moisture, dried humid air and influencing each other of both distortion, is equivalent to human body and has worn a raincoat outward.It two is the two parts that are cut off, and being connected of wood-based plate body of wall and decorative material has bigger firm intensity, avoided coming off and layering.It three is fine cracks of having avoided decorative material (for example cement mortar) self to occur.It four is that cost is low, and construction technology is simple.
