DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint forming material used for applying a surface having joints with a spraying material such as a wall surface or a road surface, a trowel coating material or the like.

[0002]

2. Description of the Related Art A joint rod having a cross section corresponding to the depth and width of a groove-shaped joint is used in this type of conventional surface treatment. As shown in FIGS. 7 (a) to 7 (c), the joint bars are detachably provided on the upper surface 3 and the lower surface 4 of the elongated member 2 having a rectangular cross section formed of foamed polyethylene, respectively. Is adhered via the adhesive layers 7 and 8. The coating materials 4 and 5 are release papers, and the adhesive layers 6 and 7 use double-sided adhesive tapes. The joint bar 1 is used by first peeling off the covering material 6 on the lower surface and sticking it to a position where joints are formed on the surface of the base to be surface-constructed, and then spraying a surface forming material such as a spraying material onto the joint bar at the height of the joint bars. The coating material 5 adhered to the upper surface 3 while the spraying material etc.
Is removed together with the spraying material or the like attached to the upper surface, and the member 2 is removed after the spraying material or the like has dried or solidified. As a result, a groove-shaped joint 9 is formed at the position where the joint rod 1 has been attached, as shown in FIG. In this case, the base surface 10 before the surface material is applied is exposed at the bottom of the joint 9. When the joint 9 is a base that requires waterproofness, for example, the outer wall of a wooden house is made of waterproof paper,
When the base is made of lath and mortar, it is a base that requires waterproofness because the life of the house will be reduced due to the ingress of water, and when constructing a surface material so as to form joints on it Before applying the surface material, the entire surface or joint position of the base surface is coated with waterproof paint, and after drying, the surface forming material 11 is applied using the joint rod 1. In addition, the surface forming materials conventionally used include a spraying material to be sprayed and a troweling material to be troweled, all of which are resin-based and inorganic-based such as cement mortar. There is.

Further, Japanese Utility Model Publication No. Hei 4-15484 discloses that a coating material molded in the same shape as a mold member is releasably adhered to the surface of a plastic or rubber mold member in which joint patterns are molded. An uneven pattern forming member in which release paper is adhered to the back surface via a peelable adhesive is disclosed. Also in the case of this uneven pattern forming member, if waterproofing is required at the bottom of the joint, waterproof coating is performed as a waterproofing treatment on the surface of the base on which the uneven pattern is formed in advance, or another waterproof plate It is necessary to install a state body (a metal plate such as aluminum), and apply an uneven pattern forming member thereon.

[0004]

When a conventional joint rod or a surface having joints is formed by using a concavo-convex pattern forming member, waterproof coating is performed separately from the step of installing the joint rod in waterproofing treatment at the joint bottom. Either a step of waiting for drying and a step of installing another waterproof plate-like body (a metal plate of aluminum or the like), which is troublesome and time-consuming. Further, when an aluminum plate is used for waterproofing joints, there is a problem that an aluminum plate punched into a joint shape is easily deformed and cannot be used if deformed during handling such as transportation. An object of the present invention is to provide a joint forming material that can solve the above problem.

[0005]

According to a first aspect of the present invention, a joint rod formed of a flexible material so as to have a cross-sectional shape corresponding to a cross-sectional shape of a predetermined joint is provided. A waterproof layer member formed of a rubber or rubber-like material in a slightly wider band shape and having a lower surface corresponding to the joint bottom side of the joint bar releasably attached to the center in the width direction of one surface, and its waterproofing. An adhesive layer is provided on a surface of the layer member on which the joint bars are attached and on a surface opposite to the surface (claim 1).

According to the measures of the invention, in its use:
First, the entire surface is adhered to the joint forming position on the base surface to be constructed by the adhesive layer on the surface opposite to the surface on which the joint rod of the waterproof layer member is adhered, for example, troweling with a surface forming material such as mortar or the like. It is almost constructed up to the joint open side surface of the joint bar by
After the surface forming material is solidified, the joint rod is removed while being peeled off from the waterproof layer member to form the joint. The flexibility of the joint bars facilitates peeling when removing the joint bars. The formed groove-shaped joint has a groove bottom formed on the upper surface of the waterproof layer member, and a side surface formed of a surface forming material that has been constructed. Since both side edges in the direction are securely positioned and fixed below the solidified surface forming material, a good waterproof structure for the base surface is obtained. Since the waterproof layer is made of rubber or rubber-like material, it is easy to adhere even if there are slight irregularities on the base surface, it is easy to construct, and plastic deformation during handling such as aluminum plate during transportation It does not become unusable.

According to the first aspect of the present invention, the joint rod is provided with a coating material releasably provided on an upper surface corresponding to an open side of the joint (claim 2).
In this configuration, in its use, the adhesive layer is applied to the joint forming position of the surface to be constructed, and a surface forming material such as a spraying material or mortar is sprayed or troweled on the joint bar to form an upper surface of the joint bar. The coating material is applied to the extent that it is almost hidden, and the surface forming material is dried or semi-solidified to peel off the coating material on the joint bar upper surface to form an open edge of the joint, and after the surface forming material has dried or solidified Thereafter, the joint is formed by removing the joint rod while peeling it off from the waterproof layer member. That is, while the surface forming material is dry or semi-solidified, the coating material is peeled off to form an open edge of the joint, so that the jointing bar can be easily formed even after the surface forming material is dried or solidified. It can be removed, the joint can be reliably formed without deformation, and the joint bar can be easily removed, as compared with the case where the joint is removed in a dry or semi-solid state.

According to a second aspect of the present invention, a thickness corresponding to a predetermined joint depth and a width slightly larger than the width of the joint are formed of a flexible material provided with a peelable coating material on an upper surface. And a waterproof layer member formed of rubber or a rubber-like material in a belt shape having the same width as the joint bar forming portion, and having a lower surface of the joint bar forming portion adhered to one surface so as to be peelable. And an adhesive layer provided on the surface of the waterproof layer member opposite to the surface to which the joint bar forming portion is adhered, and the joint at the center provided on both sides in the width direction of the joint bar forming portion. And a notch forming a corresponding joint bar (claim 3).

[0009] In this means, in use, first, the whole is affixed to the joint forming position on the surface to be constructed by the adhesive layer on the lower surface of the waterproof layer member, and then the portion outside the cut of the joint bar forming portion is removed. It is applied by spraying or troweling the surface forming material from above, and while the surface forming material is dry or semi-solidified, the coating material on the joint rod upper surface is peeled off to form an open edge of the joint, After the forming material is dried or solidified, the joint is formed by removing the joint rod while peeling it off the waterproof layer member. Since the portion outside the cut of the joint bar forming portion can press the upper surface of the joint bar forming portion and similarly press the entire upper surface of the waterproof layer member when attaching the joint forming material to the surface to be subjected to surface construction, the waterproof layer member Is securely adhered over the entire area. The rest is substantially the same as the first invention. That is, since the joint rod is flexible, peeling is facilitated when the joint rod is removed. The formed groove-shaped joint has a groove bottom formed on the upper surface of the waterproof layer member, and a side surface formed of a surface forming material that has been constructed. Since both side edges in the direction are securely positioned and fixed below the solidified surface forming material, a good waterproof structure for the base surface is obtained. Since the waterproof layer is made of rubber or rubber-like material, it is easy to adhere even if there are slight irregularities on the base surface, it is easy to construct, and plastic deformation during handling such as aluminum plate during transportation It does not become unusable.

[0010] In the means of the second invention, a portion of the joint bar forming portion outside the cut may be removed. (Claim 4). If another pressing tool (such as a roller or a spatula) is used to press the edges on both sides of the waterproof layer member, good pressurization is possible, so even if the portion outside the cut is removed. Even if the use of a pressing tool is disadvantageous, it can be compensated for by eliminating the trouble of removing it on site.

In the first and second aspects of the present invention, the joint bar is provided so that at least one of its side surfaces is inclined so that the width thereof is wider on the open side than on the bottom side of the joint. (Claim 5). In this configuration,
Since the width of the joint bar is wider on the open side than on the bottom side of the joint, the operation of removing the joint bar after the surface material is applied becomes easy. In addition, when the horizontal joint is formed on the wall surface, the lower side surface of the joint groove side surface can be inclined downward and outward, so that the joint can be drained well.

In the first and second aspects of the present invention, a plurality of joint forming materials are provided in parallel with each other, and a series of peelable coating materials are provided on the adhesive layer of each waterproof layer member. (Claim 6). In this configuration, since a plurality of joint forming materials are integrated by a series of covering materials, they can be integrated as a unit for handling and commercial transactions such as transportation. According to the sixth aspect of the present invention, since a plurality of joint forming materials are integrated by a series of covering materials, there is an effect that quantity check and packing become easy.

[0013]

FIG. 1 shows a first embodiment of the present invention.
This will be described with reference to FIG. As shown in FIG. 1, the joint forming material 20 includes a joint rod 21, a waterproof layer member 22, and an adhesive layer 2.
3 is comprised. The joint rod 21 is formed by bonding a coating material (release paper) 27 to the upper surface of an elongated rod 25 having a square cross section having a height and a width corresponding to the cross section of a desired joint via a peelable adhesive layer 26. The waterproof layer member 22 is connected to the lower surface of the body 25 via a peelable adhesive layer 28.
The material of the joint rod 21 is a material which is not crushed by construction such as a spraying material or mortar and is flexible, for example, a material made of plastic or rubber whose hardness is adjusted, and a material which is somewhat stiff. Well, for example, E
VA (ethylene-vinyl acetate copolymer), polyethylene, polypropylene, polyurethane, polyvinyl chloride,
A foam such as rubber is used.

As shown in FIG. 1, the waterproof layer member 22 is formed in a strip shape slightly wider than the width of the joint rod 21.
8 is adhered. The material of the waterproof layer member 22 is preferably a rubber or a rubber-like material having a certain degree of flexibility, waterproofness, and weather resistance. For example, butyl rubber, other weather resistant rubber, EVA (ethylene-vinyl acetate copolymer) , A non-foamed or foamed material such as polyethylene, polypropylene, polyurethane and polyvinyl chloride. This waterproof layer member 22
Is provided with an adhesive layer 23 on the lower surface, i.e., on the surface opposite to the joint bar 21 side. The adhesive layer 23 is applied to the waterproof layer member 2 on the surface of the base before the surface material such as the wall surface or the floor surface is constructed.
2 can be adhered, and is covered with a covering material 29 made of release paper having the same width as the width of the waterproof layer member 22.

A procedure for forming a joint using the joint forming material 20 will be described with reference to FIGS. First,
The coating material 29 is peeled off to expose the adhesive layer 23, and as shown in FIGS. 2 and 3A, the adhesive layer 23 is exposed.
Thus, for example, it is attached to the joint formation position of the base surface 30 to be constructed, which is a vertical wall surface. Since the waterproof layer member 22 is formed of rubber or a rubber-like material,
Even if there is a little unevenness in 0, it adheres. When performing this bonding, the joint is pressed from above the joint bar 21, but since both side edges of the waterproof layer member 22 are not pressed, this portion is, for example, a separately prepared pressing tool, for example, a roller or a spatula. It is only necessary to press down and bring it into close contact. In the part where the joints are formed so as to intersect in a three-way intersection, for example,
As shown in FIG. 2, the end of the vertical joint material 20 is overlapped on the upper surface of the edge of the waterproof layer member 22 of the horizontal joint material 20 and the lower surface is adhered. FIG. 3A shows an enlarged cross-sectional view of the portion taken along the line AA in the thickness direction. In addition, the joint of the joint forming material 20 is performed by joining the waterproof layer member 22 at the other end while leaving the waterproof layer member 22 at one end and cutting off the joint rod 21 slightly. What is necessary is just to abut the end faces of the rods 21. When the bonding of the joint forming material 20 to the joint forming position is completed, a surface forming material 31, for example, a spraying material is sprayed on the joint forming material 20 to a thickness of about the joint rod 21. FIG. 3B shows a state in which the surface forming material 31 is applied.

While the surface forming material 31 is in a semi-solid state, the covering material 27 on the upper surface of the joint rod 21 is peeled off to form an open edge 32a (see FIG. 3 (c)) as a joint. Then, after the surface forming material 31 is solidified, the joint rod 21 is connected to the waterproof layer member 2.
The joint 32 is formed by removing the adhesive layer 28 while peeling it off. Since the joint rod 21 is flexible, peeling is facilitated when the joint rod 21 is removed. The formed groove-shaped joint 32 is formed according to the shape of the joint rod 21, the bottom is formed on the upper surface of the waterproof layer member 22, and the side surface is formed of the constructed surface forming material 31. 22 are located below the solidified surface forming material (see FIG. 3 (c)), and are securely fixed.

A second embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIG. This joint forming material 20a is different from the first embodiment only in that it has removal portions 35, 35 that are removed during the on-site construction. Therefore, only this portion will be described, and other equivalent portions will be described. The same reference numerals are used in the drawings to omit the description. The removal portions 35, 35 are provided with cuts 36, 36 in the joint bar forming portion, so that the joint bars 2 are formed.
1 and formed of the same material as the rod-shaped body 21, the adhesive layer 26, and the covering material 27 of the joint rod 21, and have the same height. That is, as shown in FIGS. 4A and 4B, the joint forming material 20a is coated with the covering material 2 from below.
9. A wide sheet-like material obtained by laminating and integrating the adhesive layer 23, the waterproof layer member 22, the adhesive layer 28, the rod 25, the adhesive layer 26, and the covering material 27 is cut into a predetermined width. Cut 3 from the adhesive layer 28 to the upper joint bar forming portion
6 and 36 are provided and manufactured. The cut 36 reaches the upper surface of the waterproof layer member 22 from above. Incidentally, the configuration in which the removing units 35 are removed is the first embodiment.

The joint forming material 20a differs from that of the first embodiment in the use thereof in the following points. That is, there is a step of removing the removing units 35 in the middle of the construction step. In the removing step, the covering material 29 is peeled off and the surface of the adhesive layer 23 of the waterproof layer member 22 is removed from the base surface 30.
And after the removal step is the same as in the first embodiment. The removing portions 35, 35
Is used when the waterproof layer member 22 is positioned at a predetermined position on the base surface 30 and then bonded by pressing. Since the pressurization is performed from the upper surface of the joint rod 21 and the upper surfaces of the removing portions 35, 35, the waterproof layer member 22 is securely pressed over the entire surface, so that the waterproof layer member 22 adheres well without using another holding tool. is there. Therefore, for example, the lateral joint forming material 20a
2 and 3 (a), after removing the removed portions 35 and 35 after bonding and then removing the removed portions 35 and 35 after bonding the vertical joint material 20a and bonding. )

As shown in the sectional shape of FIG. 5 (a), the joint forming material 20b has both side surfaces 36b, 36b of the joint rod 21b inclined such that the joint 32b formed thereby has a narrow bottom side and a wide open side. This embodiment is different from the first embodiment in that the adhesive layer 26 and the covering material 27 are not provided on the upper surface of the joint bar 21b. Other equivalent parts are denoted by the same reference numerals, and description thereof is omitted.

The joint forming material 20b is used in substantially the same manner as that of the first embodiment, and joints 32b having a cross section as shown in FIG. 5 (b) are formed. Mortar, which is used when it is constructed using a trowel. When a trowel is used, the upper surface of the joint bar 21b is used as a guide surface of the trowel, and the surface forming material 31 is not applied so as to cover the upper surface of the joint bar 21b. Therefore, there is no step of removing the covering material to form an open edge of the joint, and the joint bar 21b is removed after the surface forming material 31 is applied and then solidified. The joint bars 21b can be easily removed because the side surfaces 36b, 36b are inclined, so that there is a so-called draft angle.

FIG. 6A shows a modification of the third embodiment.
(B). The joint forming material 20c has one side surface 3
6a is perpendicular to the surface of the waterproof layer member 22, and the other side surface 36b
Only the one that is inclined. As shown in FIG. 6B, the joint 32c having the cross-sectional shape is applied such that the inclined surface is located below the joint in the lateral direction of the wall surface, and the drainage in the joint is improved.

In each of the above-described embodiments, the joint forming material is provided with a waterproof layer member. By using the joint forming material for forming the joint, a special waterproofing step, that is, waterproofing for the base surface is performed. Since the waterproof condition of the joint bottom can be obtained without the necessity of the painting and drying steps, the construction is easier and the construction time is shorter than before. Further, the waterproof layer member hardly cracks, and even if cracks are formed along the joints in the concrete or mortar of the base, the cracks do not spread, and the waterproofness is not impaired.

The above-described joint moldings 20, 20a, 20
Since b and 20c are formed so as to form a series of a plurality of covering members 29, the plurality of units are combined into a single unit, which is convenient as a unit for handling and commercial transactions such as transportation. It will be good. When the manufacturing method is as described in the second embodiment, it can be easily implemented. That is, as shown in FIG. 4 (d), when cutting into the width of the joint forming material 20a, a cut 38 is provided so as to be stopped before the covering material 29 so as not to cut, and a desired number of the joint forming materials 20a are provided. What is necessary is to cut it. Reference numeral 37 in FIG. 4D denotes a cut end face. In FIGS. 5A and 6A, an embodiment in which a coating material is provided via an adhesive layer on the upper surfaces of joint bars 21b and 21c as indicated by phantom lines, In some embodiments, the adhesive layer 26 and the covering material 27 in the second embodiment are omitted.
