Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a method of applying one or more layers of desired thickness to the surface of a building base between pillars, etc., while protecting the surroundings of the pillars and other parts. An adhesive tape that is useful for determining the finish position of paint, as well as for determining the insertion (swallowing depth) position while protecting the surface from damage during insertion (incorporation) of building materials, mechanical parts, etc. .

(Prior art) When painting buildings, such as wall painting, steel frame painting, fence painting, etc., the surrounding area may be unintentionally contaminated with the painting material, and to avoid this, a wide piece of paper or plastic film is coated with adhesive tape. It is attached more widely. In addition, the surface of the base material in the recesses between the pillars of a building is sometimes coated several times with a predetermined thickness. It is necessary to configure each surface layer (finishing layer) to a desired thickness, and as mentioned above, it is necessary to prevent the coating material from unintentionally adhering to the surrounding pillars and causing stains. To do this, first apply an adhesive tape of a desired width to the pillars on both sides in a straight line up to the intended position of the finished surface of the base layer, and at the same time cover the other part of the pillar with the other part of the tape. When painting the next intermediate layer, remove the adhesive tape from the pillar, pull it down to the desired position on the finished surface of the intermediate layer, that is, by the thickness of the intermediate layer, and then straighten it again. Apply the intermediate layer to the desired thickness without staining the surrounding area, then peel off the adhesive tape in the same way and pull it down to the intended position on the finished surface of the finishing layer, that is, by the thickness of the finishing layer. As a result, a method has been adopted in which the pillars are pasted in a straight line again and again to protect pillars and other objects from staining and painted to a predetermined thickness.

In this case, instead of just covering with adhesive tape,
There is also a conventionally known method in which a wide polyethylene film or the like is attached to the adhesive part of the long edge of the adhesive tape on the side opposite to the painting positioning side, and this film is used to cover the area where stain prevention is required. ing.

Another method is to prepare three pieces of adhesive tape with a desired width or a film such as the one above, first place it on the intended finishing surface position of the finishing layer, and then apply the second piece on the intended finishing surface position of the intermediate layer. In addition, the long edges of each tape are pasted in sequence at the planned positions of the finished surface of the base layer, and after the base layer is painted, the last adhesive tape pasted is removed, and after the intermediate layer is painted, the Various thickness adjustments have been made by removing the next adhesive tape, and finally, after painting a finishing layer, removing the first adhesive tape, and at the same time, stain prevention has been performed.

In addition, when building materials such as glass plates, aluminum plates, acrylic plates, etc. are assembled into window frames or other mounting recesses, or when mechanical parts are inserted and assembled into other members, it is necessary to prevent damage or stains. At least the above-mentioned installation part of the covering material that was widely covered in the installation must be removed so as not to interfere with the installation work, but the work of removing the minimum necessary amount was surprisingly complicated, and in the end, the risk of staining etc. was ignored. They would remove a wider area than necessary, or they would use a cutter knife to cut out the necessary part under conditions that could damage the protected item.

(Problem to be Solved by the Invention) However, in painting work, it is necessary to repeatedly apply the adhesive tape as many times as the number of times the adhesive tape is to be applied, and each time the adhesive tape must be positioned in consideration of the coating thickness. These operations are difficult and inaccurate in narrow or dark places, and also require considerable skill, so improvements have been desired.

Furthermore, if a construction material that is to be incorporated into another part is completely covered with a protective material such as a polyethylene film or a buffer sheet to prevent damage, the cutter knife may be damaged. It has been desired to develop a method that can remove only the portion to be incorporated in accordance with the installation position.

(Means for Solving the Problems) As a result of intensive studies to solve the problems of the conventional method, the present inventor has found that by using a special adhesive tape, the conventional method can be easily pasted and peeled off. The present invention was completed by discovering that painting work and assembly work can be done effectively.

In the multilayer adhesive tape, the objective layer has one or more cut portions in which at least the support layer of each layer is parallel to the long edge of the adhesive tape only at one long edge portion, and Each of the adhesive tapes has a desired narrow width for positioning and curing, and in the third invention, both sides of the objective layer are composed of a protective layer and a backing layer, and the objective layer is separated from the support layer and the adhesive layers on both sides. The backing layer consists of a support layer, an adhesive layer provided on one surface thereof, an adhesive layer facing the mold release layer of the objective layer, and a mold release layer provided on the other surface, and the protective layer is In a multilayer adhesive tape consisting of a support layer and a release layer provided on one side of the support layer and facing the adhesive layer of the objective layer, the objective layer is such that at least the support layer of each layer is on the long edge of the adhesive tape. The protective layer has one or more parallel cut portions only on one elongated edge portion and each has a desired narrow width, and the protective layer has at least one support layer of each layer that is formed on the elongated end of the adhesive tape. The adhesive tape for positioning and curing has one cut portion parallel to the edge only at the long edge portion on the opposite side to the cut portion provided on the objective layer and at a desired width.

The contents of the present invention will be explained below with reference to the drawings.

FIG. 1 is a perspective view of the adhesive tape 11 according to the first invention, which is spirally wound with its adhesive side inside.

Figures 2 to 5 are enlarged perspective views taken along line A-A in Figure 1, showing various embodiments of the adhesive tape for positioning and curing according to the first invention; Commonly used.

In any of the cases shown in FIGS. 2 to 5, the adhesive tape 1 for positioning and curing consists of an objective layer 12 and a backing layer 13.
1, the objective layer 12 is composed of an adhesive layer 12a on the upper surface (objective surface), a support layer 12b below it, and a release layer 12c on the lower surface facing the backing layer 13. is composed of an adhesive layer 13a facing the objective layer 12, a support layer 13b below it, and a release layer 13c on the outer surface, and only the right edge of the objective layer 13 has the respective layers of the objective layer. Among them, at least three cutting portions 12d are provided for cutting the support layer into narrow widths parallel to the edge of the adhesive tape.

However, the cut portion 12d in FIG. 2 extends to the adhesive layer. This is an adhesive tape made by laminating a backing layer and an object layer, and cut with a cutter from the object layer side of the tape by the thickness of the adhesive layer 12a and support layer 12b to form a cut portion 12d. This is because it is on. These cuts allow the support layer to have strips 1 formed only on one edge.
2e1, 12e2, and 12e3 and the remainder 1
It is divided into 2e and 2e.

In FIG. 3, the cut portion 12d does not extend into the adhesive layer. This is similar to the case in Figure 2, where strips 12e1 and 12
When e2 and 12e3 were formed, it naturally extended to the adhesive layer, but as shown in Figure 1, the adhesive material flowed over time and the cut part disappeared while being rolled. It indicates the condition.

FIG. 4 shows a state in which the cut portion extends to the adhesive layer and further to the release layer, as in the case of FIG. 2, and shows the case where the cutter for forming the strips has made a deep cut.

FIG. 5 shows a case where the cut portion 12d is deeper than that shown in FIG. 4 and extends to the backing layer.

As mentioned above, in the adhesive tape for positioning and curing according to the first invention, at least the support layer of the objective layer is cut into strips only at one edge portion of the adhesive tape, and the rest of the tape is not cut in any way. It does not have a department. Further, the cut portion extends in various ways depending on the cutting depth of the cutter and the flow of the adhesive material after winding, but the present invention is not limited in any way by the way the cut portion extends.

Next, a method of using the adhesive tape according to the first invention will be explained.

Figures 6a to 6e show the order in which three layers of coating are applied to the surface of the base material between the pillars while curing the surfaces of the pillars 9 and 9 using the adhesive tape for positioning and curing according to the present invention. It is shown in a plan view.

As shown in FIG. 6a, the objective layer of the adhesive tape is directed toward the pillars 9, 9 to cover the parts of the pillar surfaces that should not be soiled, while the edge side of the strip of adhesive tape is placed on the surface 5S of the base material 5. The entire tape is affixed to the pillar by contact with the holder, and the backing layer is then peeled off and removed.

Next, strips 12e1 and 12e1 are removed (sixth
Figure b). Since the support layer of these strips has been cut, they can be easily removed from the edge using a fingernail or the like, and a coating material with a thickness corresponding to the removed portion is applied to the base surface 5S as the base layer 6 (see Fig. 6c). ). In this case, each edge of the strips 12e2, 12e2 serves as a line for determining the position of the surface of this base layer. In addition, since there is no cut part or strip on the opposite edge, the edge can be peeled off freely and widely, and a wide polyethylene film that may be required for curing can be sandwiched and fixed. . If there are strips, they will peel off and separate regardless of their number, making it complicated to remove the curing tape after painting.

Therefore, the adhesive tape according to the present invention is required to have stripes on one edge and no stripes on the other edge.

Similarly, the edge with the strip is the next strip 12e.
2, 12e2 removed, strips 12e3, 12e3
Using the edge of the positioning line as a positioning line, the intermediate layer 7 is applied to the base layer surface 6S (Fig. 6d), and the same process is applied to the next strip to form the strip 12.
Using the edge of the tape after e3 removal as a positioning line,
A finishing layer 8 is applied to the surface 7S of the intermediate layer, and then all remaining portions of the objective layer 12 of the adhesive tape are removed to complete the work.

FIG. 7 is a perspective view of the working state in which the strip 12e1 is being removed while broadly curing the column surface.

The support layer used in the present invention is preferably paper, cloth, or tape made of synthetic resin, but the present invention is not limited to these. The thickness of each support layer is not particularly limited, but for ease of storage in a spiral shape,
In addition, from the viewpoint of rigidity, which influences ease of handling when pasted on buildings, a thickness of about 10 to 100 microns is suitable. The components of the adhesive layer and the release layer are those commonly used for cellophane tapes and vinyl adhesive tapes, and do not need to be specified. The width of the tape depends on the area of the building etc. to be cured, but the total width of the strips is usually about 1 to 7 mm, so it is about 10 to 7 mm.
A film of about 300 mm is sufficient, and if it is insufficient, the purpose can be achieved by installing a wide-area polyethylene film on the opposite side, where there are no stripes, as described above.

The adhesive tape for positioning and curing according to the second invention can be easily wound into a spiral shape as shown in FIG. You don't have to. Therefore, if there is no adhesive layer, it can be stored simply in a long stretched state, or it can be rolled up with a protective layer on the outside of the spiral.

9 to 12 are enlarged perspective views taken along the line B-B in FIG. 8, showing various embodiments of the adhesive tape for positioning and curing according to the second invention,
The same symbols are used throughout. Of these, FIGS. 9 to 11 show the case where there is no adhesive layer on the inner surface of the adhesive tape shown in FIG. 8, and FIG. 12 shows the case where there is an adhesive layer.

In FIGS. 9 to 12, the objective layer 22 and the backing layer 23
are the same as the configuration of the first invention, and each has an adhesive layer 22.
a, support layer 22b, release layer 22c, cutting section 22
d, adhesive layer 23a, support layer 23b, release layer 23c
However, in this second invention, a protective layer 24 is further laminated on the objective layer 22.

The protective layer has a support layer 24b with a release layer 24c on the side facing the objective layer. The protective layer 24 is provided to prevent the object layer 22 from sticking to an unintended location or from strongly adhering to the release layer of the backing layer, causing the strips to fall apart while the adhesive tape 21 is being handled. Due to the presence of this protective layer 24, the objective layer does not come into contact with other objects until the actual work is performed, so that no problems occur in the above-mentioned work. During actual work, use both hands to position the adhesive tape in a predetermined position, align the strip sides of the adhesive tape, peel off the strip, and use the edges created to position the tape. Remove the protective layer from the long end by hand, expose the objective layer, attach it to an object such as a pillar, gently pull the protective layer to peel it off, and place the protective layer on the specified position until the entire length of the protective layer is removed. Adhesive tape can be attached.

In the case of the adhesive tape for positioning and curing according to this second invention, the strips are only on one edge,
It is not on the other edge side. Therefore, the side without the strips can be adapted to various curing modes, as in the case of the first invention.

Note that the work after pasting the adhesive tape is the same as in the case of the first invention.

As shown in FIG. 12, when the protective layer has an adhesive layer 24a, there is no need to temporarily hold it down by hand after positioning it at a predetermined position during the actual work, and it can be lightly temporarily fixed with the adhesive layer. The objective layer can be accurately attached to the object while sequentially pulling out and removing the protective layer from the long end of the adhesive tape.

The adhesive tape for positioning and curing according to the third invention can be wound spirally as shown in FIG. 13, but it can also be stored in a simply stretched state.

FIG. 14 is an enlarged perspective view taken along line C-C in FIG. 13, showing an embodiment of the adhesive tape according to the third invention, in which only the protective layer 34 is a thin layer of the objective layer to be described later. The object layer 32 and the backing layer 33 have the structure of the first invention, except that they are cut in the longitudinal direction at predetermined positions on the edge side without stripes and are made up of support layers 34b1, 34b2, and a release layer 34C. is the same as The protective layer is provided with a cut portion 34d in the longitudinal direction from the edge of the objective layer on the side where the cut portion 32d is not provided before reaching the cut portion, and the protective layer is provided with a cut portion 34d in the longitudinal direction.
4b2.

One way to use the protective layer is in part 3 of 34b1.
The end portion of the protective covering material (wide width film, etc.) for building materials, mechanical parts, etc. is accurately fixed to the part 32e of the objective layer, and then part 34b2 of the protective layer is peeled off, leaving the part 4b2. However, other methods of using the third invention are shown in Figs. 15a to 15d and 16a to 16a. This will be explained using Figure 16d.

The portion 34b2 of the protective layer 34 of the adhesive tape is directed toward the column surface, and the portion 34b1 of the protective layer of the long edge
The side is brought into contact with the surface 5S of the base material 5 (No. 15a
Figure), in the same manner as described for the adhesive tape application method of the second invention, the portion 34b2 of the protective layer is gradually removed from the end while being pressed against the pillar, and the cut portion 32d of the objective layer 32 is removed. Attach a certain section to the pillar (Figure 15b). Next, 34 layers of backing layer and protective layer.
A wide protective film F is pasted on the exposed part of the adhesive layer of the objective layer, except for part b1 (No. 15c)
), the film F covers the column widely (15d
figure). The coating method using strips 32e1, 32e2, and 32e3 is described in Articles 6a to 6 of the first invention.
This is the same method as explained in Figure e.

Next, a method of using this adhesive tape for positioning and curing when building materials are incorporated into a required part will be explained with reference to FIGS. 16a to 16d. The adhesive tape 31 according to the present invention is pasted around the glass plate G.
Figures a to 16d show cut end views of the vicinity of one side of the glass plate. First, 34b2 of the protective layer 34
Align the edge of the objective layer (the side with the cut portion 32d) to match the edge of the glass plate, remove the protective layer 34b2 while pressing the adhesive tape, and remove the thin strips 32e1 to 32e3 of the objective layer as well as the remaining portion 32e. (Fig. 16b). Next, lift the portion 34b1 of the protective layer and remove it, but if you use the method of pasting the edge of the protective sheet K on that portion with gassho paste and pushing it back to the original glass plate side, Although the protective sheet K has become loose as a whole, its function has not been lost. If the protective sheets K are simply pasted one on top of the other without the above-mentioned joining of hands, the protective sheets K will be pasted without loosening much (Fig. 16c). Subsequently, the backing layer 33 is removed and a suitable number of strips are removed depending on the depth of the recess H of the part T to be incorporated. In FIG. 16d, two wires 32e1 and 32e2 are removed from the front and back of the glass plate in accordance with the depth of H. With such a simple operation, while leaving as much of the protective sheet K as possible, only an amount corresponding to the depth of the recess can be removed without damaging the glass plate, and the assembly work can proceed.

In the case of this third invention as well, as mentioned above, the stripes should only be present on one long edge portion, and not on the opposite edge portion. If there is, even if a protective sheet is attached, when the backing layer is removed, the protective sheet will separate along with the stripes in that area, and although positioning may be possible, it will not be able to perform its curing functions.

The above examples will be further explained.

Example 1 Two adhesive tapes with a width of 100 mm and a thickness of 30 microns, an adhesive layer (rubber-based) on one side and a release layer (silicone-based) on the other side, were placed on one tape (backing layer). Paste the adhesive layer and the release layer of another tape (objective layer) so that they face each other, and while running over it with the backing layer side facing the flat plate side, 2 mm and 4 mm from the side edge of the adhesive tape, respectively. At a position of 5 mm from the top of the adhesive layer of the objective layer, make a cut with a round blade to a depth of approximately 32 microns to form three strips on the objective layer, and use this adhesive tape to tape the wall using the method shown in Figures 6a to 6e. Painted. As a result, even when the backing layer is peeled off and removed, the strips are not damaged, and only one strip can be removed.
The books were removed in perfect order.

Furthermore, each coating could be easily applied to the edges of each strip, and the coating thickness was accurate at 2 mm, 2 mm, and 1 mm.

The approximately 90 mm wide area without stripes was able to cover most of the pillar surface that required curing. Also, since there were no stripes, the tape was easy to remove after work was completed.

Example 2 Among the adhesive tapes for positioning and curing of the second invention, one having the configuration shown in FIG. 9 was used, with the protective layer surface facing the column side as shown in FIG. 6a, and the strip side of the objective layer facing the base material. 5 Place it on the surface and press it with both hands to temporarily position it. Remove your hand from one end of the adhesive tape, peel off the end of the protective layer 24, paste the exposed end of the objective layer in the above position, and sequentially attach the protective layer to one side. The object layer was peeled off toward the hand that had been fixed, and the entire objective layer was fixed on the pillar. After that, the same procedure as in Example 1 was carried out, and the same result was obtained, but when unwinding the adhesive tape, Since there was no work to peel off the adhesive layer of the objective layer from the release layer of the backing layer, the work of quickly pulling out the adhesive tape was easy, and there was no pain in the strips.

In addition, in this tape, the portion without stripes broadly served to protect the column surface and was easy to peel off and remove after work.

Example 3 Using the adhesive tape for positioning and curing of the third invention having a width of 50 mm and having the structure shown in FIG. 14, the periphery of a protective buffer sheet for an architectural glass plate was applied to the periphery of the glass plate in the following manner. I attached it. Width 3 of each of the strips 32e1, 32e2, 32e3 of the objective layer
mm, 2 mm, and 2 mm, align the long edge of the glass plate G with the long edge of the glass plate G so that the strip is on the edge of the glass plate G, and press it with your hand. The protective layer 34b2 is removed and the objective layer is pressed against the glass plate to fix it. Next, the portion 34b1 is lifted up together with the objective layer and the backing layer, and the 34b1 is removed. The peripheral edge of the buffer sheet K was sandwiched and fixed. This state is a state of protection from damage to the building material glass panes. When attaching the glass plate G coated with this protective material to the building member T, two strips of 32e1 and 32e2 were removed from each of the front and back sides and assembled, taking into account the depth of the recess H of 5 mm. In this case, the protective sheet portion did not need to be removed in any way, and only the built-in portion could be removed in strips, making the work more efficient.

Bonding and fixing with the above-mentioned protective material cannot be done stably if the objective layer has stripes such as those on the other edge, so it is required that there be no stripes.

(Effects) By using the adhesive tapes according to the first to third inventions, the work of determining the finishing position for painting can be performed easily and accurately, and furthermore, it is easy to protect buildings, etc. from staining. It was found that there are some effects that can be achieved. In addition, it was possible to position and incorporate building materials and mechanical parts while maintaining their protection.
