Description

Board wall anticracking adhesive tape
Technical field under the utility model: building class light lath body of wall
The prior art file that reference role is arranged:
Light lath belongs to novel wall material, is mainly used in the building internal partition wall, and its length is suitable with the floor headway, and width is 60cm, and usual thickness is three kinds of 60mm, 90mm, 120mm.Light lath adopts the on-site consolidation method to install, and cement mortar commonly used is bonding between plate and the plate, about the joint gap 5mm of plate.
Common disadvantage of light lath is that surface of wall vertical crack occurs at seam crossing easily.The generation reasons of cracks mainly is that the dried contraction and the cold contraction of plate causes.Shrink and just can in body of wall, produce tensile stress, when the stretcher strain that causes when tensile stress is not enough to offset shrinkage strain, just can produce the crack in plate and joint filler.The position that the crack takes place all is the seam crossing at plate usually, is vertical, parallel distribution.The width in crack depends primarily on the dried shrinkage value of plate and the size of cold shrinkage value, and is general all in 0.6mm.
The method that prior art solves the crack mainly contains following four kinds:
First method is to adopt the flexible joint material.Normally adopt polymer cement mortar, promptly add polymer in conventional cement mortar, the characteristics of polymer cement mortar are that elasticity is preferably arranged, and tensile property is good.Elastic mortar is used in the seam crossing of plate, about joint gap 5mm.After body of wall forms, when batten shrinks when distortion, will produce tensile stress in the body of wall, under action of pulling stress, the interior elastic mortar of plate seam can produce stretcher strain, and when stretcher strain and shrinkage strain offseted, body of wall just can not ftracture.
This method can only accomplish that at most the body of wall body does not ftracture, and can not prevent that but surface of wall from not ftractureing.This is because after batten is mounted to body of wall, also needs on body of wall Puttying and carries out incrustation.Though elastic mortar has better elastic, can not split, covering its surperficial putty and surface decoration material does not but have elastic mortar good elasticity like that.In the joint gap of 5mm, offset shrinkage strain if produce the stretcher strain of 0.6mm, its stretcher strain rate must reach 1 2%, so high stretcher strain rate, putty and surface decoration material are difficult to reach.Like this, before elastic mortar does not also ftracture, cover its surperficial material and ftractureed already.This method is owing to can not solve the external crack problem, and the elastic mortar cost is very high, therefore fails to be promoted the use of.
Second method is the joint filler ordinary mortar of plate, but pastes chemical fabric (or kraft) at the seam crossing of plate.Specific practice is that elder generation is cut into the wide band of 60mm-70mm with chemical fabric or kraft, pastes symmetrically on the wallboard along the plate seam with bonding agent then, at last Puttying and incrustation on wallboard.When the crack appears in the seam crossing of plate, the level that produces when being subjected to crack developing is pullled under the power effect, can occur tensile stress and the stretcher strain identical with crack width in the chemical fabric of crack correspondence position, because chemical fibre is furnished with tensile property preferably, chemical fabric itself can not broken by the crack.But, because brushing is big far away from chemical fabric in the stretcher strain rate of the putty on chemical fabric surface and surface decoration material, chemical fabric is very thin and be close on the crack in addition, chemical fabric stretcher strain occurs under the effect of crack, and this stretcher strain is to concentrate in the very low range identical with crack width, thereby stretcher strain rate high (surpassing 100%), this must cause the putty and the ornament materials cracking on chemical fabric surface, also there is another problem in this method, when body of wall because of making moist or temperature raises and to cause that the crack reduces or when sealing, the chemical fabric that has been stretched (or kraft) is poor because of rebound performance, can not resilience along with dwindling of crack, so cause chemical fabric (or kraft) arch camber.
The third method is the seam crossing subsides glass cloth (being fiberglass gridding cloth) at plate, this method is similar to second method, different is, glass cloth does not only have draftability but also do not have resilience, but tensile strength is very high, this method is to utilize high these characteristics of tensile strength of glass cloth, makes it play the effect of the shrinkage stress of direct opposing plate.But this method is because glass cloth almost can not stretcher strain, when shrinkage strain appears in plate, shrinking under the application of force effect, because of the stretcher strain of light lath self is not enough to offset shrinkage strain, this moment, there will be two kinds of situations: or be that glass cloth is broken, or be the seam crossing cracking or the light lath cracking of plate.
Crackings such as the 4th kind of method is not take earlier crack control measures, and be clear-cut are handled the crack later again, and this is actually the way of having no idea.More than four kinds of methods all adopted in practice, but all do not have successfully.
The prior art documentation that reference role is arranged:

---the construction industry industry standard JG/T3029-1995 of the People's Republic of China (PRC)
" glass fiber reinforced cement light porous partition board "
---the construction industry industry standard JC666-1997 of the People's Republic of China (PRC)

The purpose of this utility model: a kind of simple, convenient, practical board wall anticracking adhesive tape is provided, solves the plate seam surface cracking problem of light lath body of wall effectively.
Content of the present utility model:
As shown in Figure 1, the utility model board wall anticracking adhesive tape partly constitutes by two: elastic rubber belt 1 and separation layer 2.On special elastic rubber belt 1, with separation layer 2 (OPP film, be transparent single side self adhesive tape) scribble the one side of adhesive sticker, stick on the center position of elastic rubber belt 1 along the longitudinal, the width of separation layer 2 (OPP film) is about 1/2 of elastic rubber belt 1 width, make the compound adhesive tape that forms a kind of layer structure, this is the utility model board wall anticracking adhesive tape A.
This anticracking adhesive tape is characterised in that, as shown in Figure 4, is provided with separation layer 2 between elastic rubber belt 1 and light lath seam C, and the performance on separation layer 2 two sides has nothing in common with each other, and one side has tack, and another side does not have.Separation layer can use the OPP film or with the essentially identical material of OPP film properties feature.
Another feature of this anticracking adhesive tape is: as shown in Figure 1, the elastic rubber belt 1 that the anticracking adhesive tape uses is to make base material with cloth, adopts the method for dual coating polymeric material, the composite elastic body that is constituted.Elastic rubber belt has good draftability and resilience.
Accompanying drawing 2, Fig. 3, Fig. 4 all represent the using method and the anticracking principle of the utility model board wall anticracking adhesive tape.
Accompanying drawing 2 expression after wallboard B is mounted to body of wall, pasted anticracking adhesive tape (left side) at the seam crossing of plate and plate, pasted (in) Buddhist monk do not paste (right side) three kinds of situations.
Accompanying drawing 3 expressions have pasted the anticracking adhesive tape and body of wall has been finished incrustation sectional drawing afterwards.
Feature, using method and the anticracking principle of accompanying drawing 4 expression anticracking adhesive tapes.
When using the utility model board wall anticracking adhesive tape, as Fig. 2 and shown in Figure 4, after light lath B was mounted to body of wall, elder generation was along the seam C of plate, brushing bonding agent symmetrically, the brushing width must be greater than the width of anticracking adhesive tape A, with anticracking adhesive tape A (posting the one side of OPP film), C pastes up symmetrically along the batten seam then, makes anticracking adhesive tape A entirely cover the surface of wallboard seam C, the both sides of anticracking adhesive tape do not have separation layer partly, and B bonds together securely with batten.All plate seams are all handled with this method.After this just can carry out Puttying and incrustation to whole body of wall routinely.
When body of wall shrinks when the crack takes place seam C because of light lath B, anticracking adhesive tape A not only directly separates the putty and the ornament materials D on crack and wall surface, and owing to increased separation layer 2 (OPP film) between elastic rubber belt 1 and batten seam C, the crack is covered by separation layer 2.The two sides, front and back of separation layer 2 (OPP film) is because bonding force is very low, and the level that produces when being subjected to crack developing is pullled under the power effect, and it is very little that the level that it is delivered to elastic rubber belt 1 is pullled power, deficiency so that elastic rubber belt 1 stretch.And the elastic rubber belt 1 of separation layer 2 both sides and plate B's is bonding very firm, and the horizontal displacement that the crack produces can only pass to anticracking adhesive tape A by the position of this strong bond, and anticracking adhesive tape A is produced and the same big stretcher strain of crack width.At this moment, the part that anticracking adhesive tape A is stretched is not the scope of crack width pairing one thin " line ", but the interval identical with the width of separation layer 2, separation layer 2 has played the effect of " bridge ".Like this, anticracking adhesive tape A is with the crack---and this concentrated strain that takes place in thin " line " is distributed in the scope of " face " identical with separation layer 2 width equably.Owing to disperse width to enlarge tens of times to hundreds of times than crack width (0.1-0.6mm), though it is still identical with crack width at the stretcher strain absolute value that anticracking adhesive tape A external surface causes, but the stretcher strain rate has correspondingly reduced tens of to hundreds of times, has only below 1.7% usually.This deformation rate is less than the ultimate elongation deformation rate of surface of wall putty and ornament materials D (as coating, wallpaper etc.), and surface of wall the crack can not occur, thereby can reach the purpose that prevents the surface of wall cracking.
Because elastic rubber belt A has fabulous elasticity, another distinguishing feature of the present utility model is to be out of shape from motion tracking.When the crack diminished or disappear, anticracking adhesive tape A resilience automatically drove the external surface ornament materials and restores to the original state, thereby avoided the surface of wall arch camber at place, crack.
The utility model compared with prior art has the following advantages:
1. being the New methods in working that solves crack problem, is completely new product, compares with prior art, method, both Can effectively solve light board wall body face checking problem, can also be out of shape from motion tracking, avoid the surface of wall arch camber; No But be applicable to light board wall body, and for the body of wall that consists of with other materials for wall, as long as crack location can be in advance true Fixed, this break-preventing adhesive tape is suitable for too, can reach same effect.
2. the complete batch production production of break-preventing adhesive tape, quality, performance obtain Reliable guarantee easily, and easy to use, construction Simply, reliable for effect, avoided prior art such as field mix inaccurate, what the factors such as the difficult assurance of quality of materials caused executes Working medium amount problem.
3. economical. The one, the comparable prior art of direct cost (such as the elastic mortar method) reduce project cost; The 2nd, need not be again Cost spends processes the crack that surface of wall occurs, and has saved a large amount of after-treatment expenses. And prior art often flower exist The expense that fracture carries out the after-treatment aspect is very high, even the engineering that has is dismantled body of wall heavily because of the metope serious cracking Build, cause very large economy loss.
4. social benefit is remarkable. Country to begin at home several years ago restriction and uses solid clay brick (namely in order to protect farmland Common brick), widely popularize novel, the light wall material of application. Light lath is one of emphasis walling of applying of country. But, because the light board wall body cracking phenomena is very general, so far this problem all there is not good solution both at home and abroad, The problem of Cracking of light board wall body is the major obstacle that impact is promoted the use of always. The utility model crack-proof adhesive belt for plate wall by In can effectively solve the cracking this key technology difficult problem, thereby its appearance will promote effectively light lath popularization should With, for national materials for wall innovation great cause is made contributions.
