Therefore, when wallpaper or the wall paper material such as cloth, the subsides of synthetic resin cross are pasted above corner material and position, corner time, can produce the paste position skew of wall paper material, corresponding sides angular position bight shrivelled etc. paste bad.
Summary of the invention
The present invention is intended to the shortcoming overcoming prior art, provides a kind of wall corner decoration material and the manufacture method thereof that can carry out good construction to the position, corner of building external angle or inner corner portion.
For reaching above-mentioned purpose, the invention provides a kind of wall corner decoration material that can be pasted onto the position, corner of external angle that two walls intersect or inner corner portion, described wall corner decoration material is by having the transparency and the ribbon plastic sheet material that can have an X-rayed forms, in the inside and outside two sides of described plastic sheet, one side is had at least to be the central portion being configured in broadside, together with the channel form fold line arranged continuously at long side direction along this plastic sheet, form the both sides of this fold line.Along this fold line, be equipped with folding pair of right and left in inside and outside both direction dull and stereotyped.
Utilize the present invention, the position, corner of external angle or inner corner portion can be made to construct under kilter.
Specifically, when wall corner decoration material of the present invention is pasted onto position, corner, the central portion of wall corner decoration material broadside is folded into the angle corresponding with the bight at position, corner, make the bight of wall corner decoration material after folding and the bight at position, corner be consistent simultaneously, then paste the wall at position, corner temporarily.
Next putty-painting wall fitted up to the position, corner in wall corner decoration material, simultaneously with putty by floating for the surface finish at position, corner, position, corner can be made to occur acute angle.Polish floating after, wallpaper or the wall paper material such as cloth, the subsides of synthetic resin cross can be labelled to position, corner.With the wall finishing adhesive beyond putty, wall corner decoration material can also be pasted position, corner.
When wall corner decoration material of the present invention is pasted position, corner temporarily, can by having the face side of the wall corner decoration material of the transparency, perspective is pasted with the wall at the position, corner of this wall corner decoration material.Like this, operating personnel just can estimate and confirm whether wall corner decoration material has closely pasted on the wall at position, corner.
Like this, even if the part of wall corner decoration material occurs peeling off from the wall at position, corner or floating waiting stickup bad, before stickup wall paper material, for the stickup situation of wall corner decoration material being pasted onto position, corner temporarily, also can be modified to and fit tightly on the wall at position, corner.
Its result is exactly, wall paper material can be pasted external angle or position, inner corner portion corner attractive in appearance while, also can by this position, corner refine to kilter.
In addition, when wall paper material being pasted the position, corner in wall corner decoration material, can effectively prevent the stickups such as the paste position of wall paper material offsets, the generation of the bight at position, corner is shrivelled bad.
The above-mentioned transparency refers to, comprises transparent and translucent, by the wall corner decoration material at position, corner being pasted onto external angle or inner corner portion, is enough to the transparency of having an X-rayed the wall forming position, corner.
Have again, above-mentioned plastic sheet is the monomer sheet material being implemented plastic shaping by PETG (PET), amorphous PETG (A-PET), polypropylene (PP), vinyl chloride (PVC), biodegradable plastic etc., or the composite sheet that the plastic sheet be made up of the material beyond above-mentioned plastics or film are composited is formed.
Plastic sheet is that the plastics being main component by above-mentioned PETG (PET) are formed, then can not produce such as toxic gas or sharp aroma, pernicious gas etc. when burning, can reduce the impact on natural environment.
Fold line is located at plastic sheet certain one side inside and outside in two sides, although can flexibly towards wall corner decoration material inside and outside both direction fold, if but be arranged on the inside and outside two sides of plastic sheet, then not only can obtain equal flexibility and folding property in inside and outside both direction, and be located at compared with a face, the recuperability returning to folding front state due to it is lower, and its flexibility is higher than the corner material of prior art.
And in the winter time under cryogenic conditions, as wall corner decoration material of the present invention, its folding property is also substantially constant.
That is, the fold line in the present embodiment, the plastics corner material that its intensity and folding property are sold than market is good, and the reducing power returning to folding front state is less, thus can keep being folded into the angle corresponding with position, corner constant.And, be also collapsible into the either direction on inside and outside two sides, thus also could be adhered to the position, arbitrary corner of external angle or inner corner portion.
As example of the present invention, in the inside and outside two sides of described plastic sheet, have at least one be configured in broadside central portion near, but also the long side direction had along described fold line arranges, has the visible section of identifiable design color.
Utilize the present invention, when wall corner decoration material is pasted onto position, corner, operating personnel can estimate and confirm whether this wall corner decoration material has pasted position, corner conscientiously.
Specifically, when transparent corner material is pasted position, corner, corner material is folded to the angle corresponding with the bight at position, corner and paste.But even if the bight of this folding corner material bends, because the whole of corner material and bight thereof are transparent, operating personnel is also difficult to confirm that whether the bight of corner material is bending with visual type.
So, after having pasted above-mentioned wall paper material, more owing to finding the situation that the bight being pasted onto the corner material at position, corner bends, the construction of acute angle type cannot be carried out in opposite side angular position.In addition, because construction is repeated in needs opposite side angular position, operation is more time-consuming.
Adopt wall corner decoration material of the present invention, when this wall corner decoration material is pasted position, corner, the bight being folded into the wall corner decoration material of the angle of corresponding sides angular position bends, the visible section be then arranged in wall corner decoration material can bend, operating personnel only needs the visible section of visual wall corner decoration material, can confirm that the bight of wall corner decoration material is with or without bending.
Like this, before the above-mentioned wall paper material of stickup, wall corner decoration material can be modified to the state conscientiously pasting position, corner.
Thus namely there is acute angle in the position, corner of external angle or inner corner portion, improve construction precision.
Separately, as the householder method arranging above-mentioned visible section, mainly contain: with the method for the color ink printing such as redness, blueness, black, with the method for writing brush or hairbrush coating oil-based ink, paste to specified color painted adhesive tape method, by sand paper or the sandblasting method etc. at the trickle scar of Surface Machining.
As example of the present invention, for described flat board, while the thickness direction of this flat board forms multiple through hole portion, this some holes portion can be arranged along the long side direction of described flat board at interval according to the rules.
Utilize the present invention, wall corner decoration material can be pasted onto on the wall at position, corner securely.
Specifically, by on putty-painting to the wall corner decoration material being pasted onto position, corner time, the putty entering plate well portion also can be applied on the wall at position, corner, according to the bonding force of this putty, wall corner decoration material can be securely adhered on two walls at formation position, corner.
Consequently, can be acute angle-shaped stickup along the position, corner of building external angle or inner corner portion by wall corner decoration material.
In addition, as example of the present invention, at least one face in described flat board inside and outside two sides, any one in multiple fine recesses or protuberance can be set, or impose multiple trickle recess and protuberance simultaneously.
Utilize the present invention, while the sticking state keeping wall corner decoration material, the bonding force expecting size can be obtained.
Specifically, flat board arranges recess or protuberance, the wall finishing adhesives such as convenience putty or adhesive, with this wall finishing adhesive is coated on compared with flat surfaces, the cohesive of wall finishing adhesive to flat board is higher, the larger bonding force needed for the sticking state of can be maintained wall corner decoration material or wall paper material.
As the householder method imposing above-mentioned recess or protuberance, mainly contain: with wire brush scratch method that planar surface carries out processing, the method for carrying out processing with the sand paper wiping planar surfaces of No. 40 ~ about No. 100, with hard particles sandblasting so as to scabble method that planar surface carries out processing, method etc. that the roller pressing planar surface that is provided with multiple protuberance with periphery carries out processing.As mechanically implemented these methods, recesses machined or protuberance can be convenient to.
That is, as long as use a certain method selected from said method to carry out recess or protuberance processing at planar surface, and impose above-mentioned wall finishing adhesive on the surface of this recess or protuberance, the cohesive of this wall finishing adhesive can just be improved.
Above-mentioned recess can be made up of ditch portion or cave portion, indenture portion etc.Protuberance can be made up of burr or projection etc.
In addition, as example of the present invention, area is set up for described recess and described protuberance, more than 10% of unit area can be set as.
Adopt the present invention, can by the bonding force obtained needed for the sticking state keeping wall corner decoration material.
Specifically, recess or protuberance set up area, such as, say with 1cm
2be a unit area, if to less than 10% of this unit area, be just difficult to join the wall finishing adhesives such as cloth putty or adhesive, the bonding force needed for sticking state keeping wall corner decoration material or wall paper material cannot be obtained.
But, if the area of setting up of recess or protuberance is set to more than 10%, above-mentioned wall finishing adhesive just easily joins cloth, namely the bonding force of wall finishing adhesive can act on the part or all of of the recess set up or protuberance, and then raising cohesive, thus the larger bonding force needed for the sticking state of be maintained wall corner decoration material or wall paper material.
In addition, as example of the present invention, can by the inner peripheral surface in described hole portion, a certain surface from the described wall being pasted onto described flat board starts. and slowly towards other surface of this flat board, formation internal diameter becomes the large conical surface gradually.
Utilize the present invention, the aesthetics of pasting wall paper material along position, corner can be realized, this position, corner refine is become kilter.
Specifically, the hole portion that flat board is formed, having can from another taper surface towards other face slow enlarged inner diameter relative with wall, be convenient to the depths in the wall finishing adhesive access aperture portions such as putty, thus keeping going deep into the state of inside, hole, the bonding force of wall finishing adhesive effectively can prevent dull and stereotyped being separated with wall.
Can prevent flat board or wall from occurring to peel off or float thus, improve the cohesive of wall corner decoration material opposite side angular position simultaneously.In addition, the cohesive of wall paper material to wall corner decoration material can also be improved.
Consequently, when above-mentioned wall paper material is affixed to position, corner, the paste position of the wall corner decoration material that can conscientiously prevent this position, corner from pasting is shifted.
The angle of inclination of the conical surface, suggestion is set as the angle within 5 degree ~ 80 degree scopes.
As example of the present invention, for the described wall be pasted onto on described flat board, possess this gluing flats to the adhesive means on this wall.
Utilize the present invention, when carrying out polishing floating in opposite side angular position, the paste position of the wall corner decoration material being pasted onto position, corner can be prevented to be shifted.
Specifically, when pasting wall corner decoration material along position, corner, while left and right flat board is pressed two walls extremely forming position, corner, the opposite face of this flat board and wall can be pasted with pressure sensitive adhesive or bonding adhesive, two-sided tape etc. temporarily.
Consequently, utilizing wall finishing adhesive by before floating for the surface finish at position, corner, wall corner decoration material can be pasted position, corner temporarily.
As example of the present invention, at least one face in the inside and outside two sides of described plastic sheet, along the long side direction of this plastic sheet, graduation mark can be set at regular intervals.
Utilize the present invention, according to the length corresponding to position, corner, can use after correct cutting wall corner decoration material.
Specifically, even if do not use the survey tool such as tape measure or scale, utilize the graduation mark that wall corner decoration material is arranged, also can the size at position, correct measurement corner.The graduation mark position measured, pastes after wall corner decoration material being cut into the length corresponding to position, corner with scissors or the cutter such as pocket knife, cutting knife, can make full use of wall corner decoration material and can not waste.
Consequently, when constructing in opposite side angular position, the discarded amount of wall corner decoration material is less, effectively can reduce construction cost.
As example of the present invention, described graduation mark is arranged along the long side direction bottom this fold line, with the thinnest part of this fold line thickness for benchmark, after leaving this part, form more shallow trench gradually; With the thickness of described plastic sheet for benchmark, the width of described fold line is located in the scope of 1.5 times ~ 5 times; With the thickness of described plastic sheet for benchmark, the degree of depth of described fold line is located in the scope of 0.4 times ~ 0.95 times; With the degree of depth of described fold line for benchmark, the height of the convex shaped part of described fold line is located in the scope of 5% ~ 95%.
Utilize the present invention, the sheet material that intensity and folding property are good, be aided with the line with a scale of fold line can be obtained.
Specifically, by the auxiliary lines on plastic sheet, with the thinnest part of this fold line thickness for benchmark, along with this part away from, form the trench slowly shoaled.While making to become the bottom of fold line than the convex shaped part of fold line depth as shallow, long side direction can be aligned to along the bottom of this fold line.
About the width of fold line, be with the thickness of plastic sheet for benchmark, be located in the scope of 1.5 times ~ 5 times.About the degree of depth of fold line, be with the thickness of plastic sheet for benchmark, be located in the scope of 0.4 times ~ 0.95 times.
The hierarchy structure of fold line is different because of the thickness of plastic sheet, and with the thickness of plastic sheet for benchmark, suggestion width is located in the scope of 1.5 times ~ 5 times, the degree of depth is located in the scope of 0.4 times ~ 0.95 times.
That is, about the width of fold line, with the thickness of plastic sheet for benchmark, can be located in the scope of 1.5 times ~ 5 times.
The width of fold line is located at less than 1.5 times, and plastic sheet is folded into fold line when being positioned at outside, the radius of curvature (R) of fold line can diminish, and easily produces crack or cracking etc.
About the degree of depth of fold line, be with the thickness of plastic sheet for benchmark, be located in the scope of 0.4 times ~ 0.95 times.
When the degree of depth of fold line being set to below 0.4 times, contrary to the above, for the part that the thickness forming fold line is the thinnest, the thickness of thick portion can be thickening, and the reducing power of plastic sheet self or repulsive force can become large, and the folding property of fold line can be deteriorated.
In addition, when the degree of depth of fold line being set to more than 0.95 times, for the part that the thickness forming fold line is the thinnest, the thickness of thick portion can be thinning, and the reducing power of plastic sheet self or repulsive force can diminish.
Therefore, although can conveniently be folded along desired direction and curvature by plastic sheet, there is the probability in damaged or hole etc. also in increase.
For forming the thinnest part of fold line thickness, the average thickness of thick portion determined by the thickness of plastic sheet.But the thickness of its thick portion, with the thickness of plastic sheet for benchmark, advises thickness to be located in the scope of 15% ~ 40%.
When the thickness of thick portion is set as the thinness of less than 15%, the rigidity of thick portion can die down, and this part is easily damaged, due to the relation of machining accuracy, produces the probability in hole also in increase.
In addition, as the thickness of thick portion being set as the thickness of more than 40%, then the rigidity of thick portion can strengthen, and the folding property of fold line can be deteriorated.
Arranging protruding object is part in order to strengthen fold line thinner thickness, along the bottom of the thinner thickness of fold line, and can continuously or the arranging along long side direction of intermittent.
Ledge width or height, spacing are very important for the fold line that acquisition folding property is outstanding.That is, by adjusting the ratio of ledge width, length etc., the bending strength of the part of adjustable foldable line thinner thickness.
That is, the protruding average thickness strengthening fold line long side direction, fold line becomes softness and is easy to bending soft, thus can obtain that folding property is outstanding, the sufficient line drawing structure of intensity.
About height of projection, to advise with the degree of depth of fold line, for benchmark, being located in the scope of 5% ~ 95%.
Be low to moderate less than 5% as height of projection established, then the effect adjusting the bending strength of fold line thinner thickness part will reduce greatly.
Ledge width along be arranged in fold line long side direction convex shaped part spacing and change, advise with the thickness of plastic sheet for benchmark, its width be located in the scope of 1 times ~ 10 times.In addition, be raised in the long side direction of fold line, both intersecting angles also can in the scope of 15 degree ~ 90 degree.
As embodiments of the invention, in the inside and outside two sides of described plastic sheet, in the bottom of the auxiliary lines at least one face, the convex shaped part formed and the concavity portion lower than this convex shaped part can be arranged in long side direction along this fold line bottom this.
Utilize the present invention, can prevent towards the folded of wall corner decoration material, be pasted onto wall paper material on fold line and occur damaged.
Specifically, in prior art, the hinge of corner material folds toward the outer side, namely the wall paper material be pasted onto in this corner material can fit tightly on the smooth face of exposing hinge face side, surface after whole being adjacent to, namely the bonding force of putty or adhesive etc. can have an effect, and namely the corner parts being pasted onto the wall paper material on hinge can obtain larger pulling force.
Therefore, for the corner parts of the wall paper material corresponding with hinge, the easy generation of existence is damaged or wrinkling, the problem that wall paper material cannot be pasted along position, corner.In addition, even if the radius in hinge R face is radius 0.2mm described later, still the problems referred to above can be there are.
To this problem, wall corner decoration material of the present invention is arranged in concavo-convex along long side direction by the bottom of fold line and projection, at the position, corner of external angle by fold line in outside time, namely the wall paper material be pasted onto in this wall corner decoration material partly can contact fold line and have concavo-convex R face.
Consequently, the pulling force giving wall paper material is less, not only can prevent the wall paper material on pasting and folding line from occurring damaged or wrinkling etc., and can realize wall paper material and paste along the ideal at position, corner.
As example of the present invention, for the described fold line of described wall corner decoration material being stacked to outside, the radius in the R face that folded part is formed can be established to more than 0.2mm.
Utilize the present invention, when constructing to wall paper material and being covered by the fold line that the outside of wall corner decoration material is exposed, can prevent the part corresponding with this fold line from breakage occurring.
Specifically, such as, when wall corner decoration material being pasted onto the position, corner of external angle, outside is in for making fold line, paste again after wall corner decoration material is folded, but the R radius surface exposed due to the outside of this fold line is located at more than 0.2mm, thus can effectively prevent the adhesive portion of the wall paper material corresponding with the fold line exposed outside wall corner decoration material from breakage occurring.
Consequently, attractive in appearance for wall paper material being pasted onto can be pasted in the wall corner decoration material at position, corner.
As example of the present invention, the thickness of described plastic sheet can be located in the scope of about 0.2mm ~ 0.8mm.
Utilize the present invention, intensity and the good fold line of folding property can play booster action to plastic sheet.
Specifically, when the thickness of plastic sheet is established to below 0.2mm, because rigidity dies down, be not suitable for opposite side angular position and strengthen.In addition, if establish to more than 0.8mm by the thickness of plastic sheet, then due to rigidity grow, not only the folding property of fold line can be deteriorated, also can the section of generation difference when pasting above-mentioned wall paper material, and the aesthetic property at position, corner can be deteriorated.
Therefore, advise the thickness of plastic sheet to be located in the scope of about 0.2mm ~ 0.8mm.
In addition, what the present invention relates to is the manufacture method that the wall corner decoration material of pasting is carried out at the position, corner of external angle or the inner corner portion intersected along two walls, be provided with the upper and lower roller that manufactures for a pair to pressurize towards long side direction to the ribbon plastic sheet material that the transparency can be had an X-rayed, at least the line cutter trench fold line of this plastic sheet being played to booster action can be set at the periphery of a roller, the line cutter of described manufacture roller is pressed to the broadside of described plastic sheet, utilize the described upper and lower roller that manufactures for a pair that described plastic sheet is reached long side direction simultaneously, for the central portion of described plastic sheet broadside, described fold line can play continuous print booster action at long side direction.

As shown in Figure 3, Figure 4, above-mentioned plastic sheet 2 is made up of PETG (PET), and thickness T1 is positioned at the scope of 0.2mm ~ 0.8mm.
In addition, be arranged on the fold line 4 in plastic sheet 2, from the long side direction A of this plastic sheet 2, be made up of the section semicircle shape curved face part 4a forming curve form, from the broadside B of the bottom center of curved face part 4a, by the protruding 4b(of smooth section semicircle shape with reference to Fig. 3 (a), (b)) form.
The position, front and back of protruding 4b, the degree of depth D1 defining fold line 4 and the 1st ditch portion 4c being positioned at same position.In addition above protruding 4b, form the 2nd ditch portion 4d also more shallow than the 1st ditch portion 4c.Along the long side direction A bottom fold line 4, the 1st ditch portion 4c and the 2nd ditch portion 4d arranges alternately.
Curved face part 4a is centered by the imaginary centres point P being located at fold line 4 broadside central portion, form level and smooth radius of curvature, the thick portion 4e simultaneously formed with the part that thickness in fold line 4 is the thinnest is for benchmark, along with from thick portion 4e away from, thickness is thinning gradually, from the long side direction A of plastic sheet 2, form level and smooth section semicircle shape.
That is, when the radius of curvature of curved face part 4a is less, the inner side of fold line 4 easily produces crack, the fold line 4 that suggestion processing radius of curvature is larger.
Protruding 4b is orthogonal with the long side direction A of fold line 4, is formed at broadside B.Meanwhile, along the long side direction A bottom fold line 4, arrange multiple at predetermined intervals.
The width W 1 of fold line 4 is with the thickness T1 of plastic sheet 2 for benchmark, and width is (with reference to Fig. 4) in the scope of 1.5 times ~ 5 times.
If the width W 1 of fold line 4 is located at less than 1.5 times, then, when folding plastic sheet material 2 is to make fold line 4 be in outside, namely the radius of curvature (R) of fold line 4 can diminish, and easily crack or cracking etc. occurs.
In addition, when folding plastic sheet material 2 is to make fold line 4 be in inner side, in the broadside of fold line 4, two bights can join mutually, and the folding property of plastic sheet 2 can be deteriorated.
As established to more than 5 times by the width W 1 of fold line 4, then the pressure when the line cutter (not illustrating) processed by line drawing presses to plastic sheet 2 can be comparatively huge, and the machining accuracy of fold line 4 can be deteriorated.
In addition, when the width W 1 of fold line 4 is wider, fold line 4 can expose to outside, and the outward appearance of folded part can become very ugly.Further, the folding position of fold line 4 is easily to broadside displacement, the precision folded along fold line 4 by plastic sheet 2 cannot be ensured.
The degree of depth D1 of fold line 4 is with the thickness T1 of plastic sheet 2 for benchmark, and the degree of depth is (with reference to Fig. 4) in the scope of 0.4 times ~ 0.95 times.
If the degree of depth D1 of fold line 4 to be established the more shallow degree of depth to less than 0.4 times, then contrary to the above, in fold line 4, the thickness T2 of the thick portion 4e of the most thin section of thickness namely can be thickening, and the reducing power of plastic sheet 2 self or repulsive force can become large, and the folding property of fold line 4 can be deteriorated.
If established by the degree of depth D1 of fold line 4 to more than 0.95 times, then the thickness T2 of the thick portion 4e that the part that fold line 4 thickness is the thinnest is formed will be thinning, and reducing power or the repulsive force of plastic sheet 2 self then can diminish.
The thickness T2 of thick portion 4e is with the thickness T1 of plastic sheet 2 for benchmark, and thickness is (with reference to Fig. 4) in the scope of 0.05 times ~ 0.5 times.
If established by the thickness T2 of thick portion 4e and be as thin as less than 0.05 times, then the rigidity of thick portion 4e will die down, and this part is easily damaged, and due to the factor of machining accuracy, the probability that hole occurs will strengthen.
In addition, as established to more than 0.5 times by the thickness T2 of thick portion 4e, then the rigidity of thick portion 4e will strengthen, and the folding property of fold line 4 is deteriorated.
The height of protruding 4b is with the degree of depth Dl of fold line 4 for benchmark, and it is highly positioned at the scope of 5% ~ 95%.
If the height H of protruding 4b established and be low to moderate less than 5%, then for the thickness T1 of fold line 4, the effect of adjustment thinner point bending strength will significantly reduce.
The width W 2 of protruding 4b along with the spacing change of protruding 4b of long side direction A being arranged in fold line 4, still with the thickness T1 of plastic sheet 2 for benchmark, the width W 2 formed is in the scope of 1 times ~ 10 times.
In addition, about protruding 4b, can being the angle of the crossing of 15 degree ~ 90 degree with the long side direction A of fold line 4, as reduced by this intersecting angle, being then conducive to repulsive force when weakening folding.
If the width W 2 of protruding 4b established narrow to less than 1 times, then the width of thick portion 4e will broaden, protruding 4b the stiffening effect that rises namely can decline, the intensity of plastic sheet 2 self also can significantly reduce.
If established by the width of protruding 4b wide to more than 10 times, then namely the width of thick portion 4e can narrow, protruding 4b the stiffening effect that rises namely can strengthen, reducing power or the repulsive force of plastic sheet 2 self will increase, and namely the folding property of fold line 4 can be deteriorated.
According to foregoing, suggestion 1 to 1 ground arranges the width of protruding 4b and thick portion 4e.Specifically can adjust according to the intensity of the thickness T1 of plastic sheet 2 or fold line 4 and folding property.
In addition, the outstanding side corner sections r1 of protruding 4b, forms the level and smooth R face (with reference to Fig. 3 (b)) of more than 0.01mm.
As the R face making the outstanding side corner sections r1 of protruding 4b form more than 0.01mm, then time along fold line 4 folding plastic sheet material 2, can effectively prevent this protruding 4b from the problem such as defect or crack occurring.
In addition, when folding plastic sheet material 2 is to make fold line 4 be in outside, the outstanding side of protruding 4b both there will not be corner angle, and finger tip is also not easy to grab bad, plays the effect that feel is good.
In addition, two bight r2 of fold line 4 broadside, form the level and smooth R face (with reference to Fig. 4) of more than 0.01mm.
As the R face making two bight r2 of fold line 4 broadside form more than 0.01mm, then when along fold line 4 folding plastic sheet material 2, can effectively prevent the part of the thinner thickness of fold line 4 from crack or cracking, powder etc. occurring.
Next, Fig. 5 is utilized illustratively above-mentioned ditch portion 8 to be arranged on the surface of dull and stereotyped 3 with the method helped out.

In addition, the height H 2 of burr 8a (with reference to Fig. 5 (a)) in the scope of about 0.005mm ~ 0.15mm.
But, first to the Surface Machining of above-mentioned ditch portion 8 at flat board 3, and then fold line 4 can also be set.In addition, for the whole surface of dull and stereotyped 3, also ditch portion 8 can be set with basic impartial interval.Further, also ditch portion 8 can be located at the whole back side of dull and stereotyped 3.
In addition, also burr 8a can be located at the local location of dull and stereotyped 3, such as need the position being coated with putty 50 grade.
Following explanation, adopts above-mentioned wall corner decoration material 1, the position, corner 40 of external angle 20 shown in Fig. 7 is carried out to the method for acute angle construction.
First, as shown in Figure 6, Figure 7, during the fold line 4 of folding wall corner decoration material 1, in conjunction with the angle at the position, corner 40 that two wall 40a in external angle 20 intersect, it is made to give prominence to toward the outer side.
Make the bight of the wall corner decoration material 1 folded according to the angle corresponding with position, corner 40, be consistent with the bight at position, corner 40, by left and right dull and stereotyped 3 by two the wall 40a forming position, corner 40, simultaneously with the adhesive 6(reference Fig. 2 be coated on these dull and stereotyped 3 back sides) paste along two wall 40a temporarily.
Like this, the position, corner 40 of external angle 20 just can have been made in acute angle.In addition, the surface putty 50 completing opposite side angular position 40 polish floating before, the paste position of wall corner decoration material 1 can be prevented to be shifted.
The wall corner decoration material 1 of interim stickup is made up of the plastic sheet 2 with the transparency, can from the wall 40a at the face side perspective position, corner 40 of wall corner decoration material 1.Like this, whether operating personnel just can confirm the wall 40a (with reference to Fig. 6) at wall corner decoration material 1 position, subsidy corner 40 with visual type.
Even if wall corner decoration material 1 has occurred to peel off from the wall 40a at position, corner 40 or float to wait stickup bad, before sticking wallpaper or the wall paper material (not illustrating) such as cloth, the subsides of synthetic resin cross, for the wall corner decoration material 1 pasting position, corner 40 place temporarily, the wall 40a to being closely adjacent to position, corner 40 can be repaiied.
In addition, when wall corner decoration material 1 is pasted position 40, corner, if the bight being folded into the wall corner decoration material 1 of the angle corresponding with position, corner 40 bends, the visible section 7Y that wall corner decoration material 1 is arranged also can bend, operating personnel only needs the visible section 7Y of visual wall corner decoration material 1, can confirm that whether the bight of wall corner decoration material 1 is bending at once.
By above-described embodiment, before stickup wall paper material, stretching for wall corner decoration material 1 correction can be pasted position, corner 40 place.Consequently, the position, corner 40 of external angle 20 or inner corner portion 30 can present acute angle, and then improves the precision of construction.
Next, by putty 50 from while wall corner decoration material 1 is coated onto position, corner 40, also can be coated onto the whole surface of the flat board 3 of wall corner decoration material 1 uniformly.In addition, while also coating putty to the multiple hole portion 5 forming left and right dull and stereotyped 3, the segment difference section of the end and wall 40a that also can be coated with wiping tablet 3 is divided, and is then polished floating.
Then, the wall corner decoration material 1 can pasted from position, corner 40 place, along two the wall 40a forming position, corner 40, paste above-mentioned wall paper material (not illustrating), and by position, corner 40 refine of external angle 20 to acute angle.
Next, enter into the putty 50 in hole portion 5, namely can be combined into one with the putty 50 be coated onto on wall 40a, thus wall corner decoration material 1 firmly can be pasted on two wall 40a at formation position, corner 40.In addition, when utilizing putty 50 to carry out polishing floating, the time of repeatedly smearing putty 50 can be saved, thus shorten the activity duration being coated with putty.Further, the putty 50 in ostium portion 5, can be combined into one with the putty 50 being coated in dull and stereotyped 3 surfaces, and then wall paper material firmly can be pasted the surface of dull and stereotyped 3.
As mentioned above, while wall corner decoration material 1 is folded into the angle corresponding with the position, corner 40 of external angle 20, the bight of the wall corner decoration material 1 being folded into the angle corresponding with position, corner 40 can be made, be consistent with the bight at position, corner 40, paste, so position, corner 40 can be modified into acute angle because this wall corner decoration material 1 is interim along position, corner 40.
In addition, wall corner decoration material 1 can be rolled into cylindrical shape and bring to job site.
In addition, because the fold line 4 of wall corner decoration material 1 structurally can fold to the inside and outside both direction of this wall corner decoration material 1, the purposes of wall corner decoration material 1 is not limited to the external angle 20 shown in Fig. 7, also can be used to the position, corner 40 of the inner corner portion 30 shown in Fig. 8 to be modified into acute angle.
In addition, the reducing power that fold line 4 due to wall corner decoration material 1 is reset to folding front state is more weak than corner material of the prior art, after two wall 40a at the position, corner 40 along external angle 20 or inner corner portion 30 are folded, wall corner decoration material 1 can keep folding angles constant.
That is, as corner material of the prior art, before the sclerosis such as putty 50 or adhesive, without the need to keeping the folded state of wall corner decoration material 1, thus operating efficiency wall paper material being pasted position, corner 40 can greatly be improved, and can the reduction of erection time.
Further, for above-mentioned wall paper material, due to be on the wall corner decoration material 1 being pasted onto position, corner 40 place, paste acutangulate along position, corner 40, so the construction effect at position, corner 40 is good.
In addition, the hole portion 5 formed on dull and stereotyped 3, its shape is from relative with wall 40a a back side, and along with slowly launching to other surface, its internal diameter footpath also can become large, tapered.Putty 50 is depths, access aperture portion 5 easily, when the putty 50 entering into hole portion 5 is combined into one with the putty 50 be coated on wall 40a, the stickup resistance that putty 50 produces namely can by dull and stereotyped 3 and wall 40a decompose.
Like this, dull and stereotyped 3 just can be prevented from wall 40a stripping or float, improving the cohesive of wall corner decoration material 1 opposite side angular position 40.
Consequently, when wall paper material is pasted position 40, corner, the paste position of wall corner decoration material 1 conscientiously can be prevented to be shifted, thus wall paper material can be realized paste along the ideal at position, corner 40.
In addition, even if do not use the survey tool such as tape measure or scale, utilize the graduation mark 7X be arranged in wall corner decoration material 1, can the size at position, Measurement accuracy corner 40, according to the above, along the graduation mark 7X measured, with scissors or the cutter such as pocket knife, cutting knife, wall corner decoration material 1 is cut off along broadside, can effectively utilize wall corner decoration material 1 and be unlikely to waste.
Therefore, use after wall corner decoration material 1 can being cut into the length corresponding with position, corner 40 or width.In addition, when constructing in opposite side angular position 40, the discarded amount of wall corner decoration material 1 is less, can reduce construction cost.
In addition, when wall corner decoration material 1 being pasted the position 40, corner of external angle 20, paste after wall corner decoration material 1 being folded and make fold line 4 be in outside, exposing to the R face 9 in the outside of fold line 4, its radius is (with reference to Figure 14) that be located at more than 0.2mm.So, even if the wall corner decoration material 1 of during construction, position, corner 40 being pasted is by wall paper material covers, also can prevent the part corresponding with the described R face 9 of wall paper material from breakage occurring.
Therefore, can along the R face of wall corner decoration material 1 being pasted onto position, corner 40 place, stickup wall paper material attractive in appearance.
Have again, there is the bottom of the curved face part 4a of the concavity of fold line 4, together with protruding 4b, arrange towards long side direction A concave-convex surface, fold line 4 is made to be positioned at outside when carrying out folding, be pasted onto the wall paper material in wall corner decoration material 1, partly can contact the concavo-convex R face 9(reference Figure 14 with fold line 4).
