BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a string material (building ruler, corner ruler) suitable for forming a projecting angle of a wall in a building. The present invention also relates to a method for forming a projecting angle of a wall by using the above-mentioned cord material.

2. Description of the Related Art It is desirable that the projecting angle of a wall in a building (the ridge angle where two walls meet) is as straight as possible, but when the projecting angle of the wall is formed by visual inspection by a builder. However, it was difficult to make it perfectly straight, and the appearance of the product often varied due to the skill of the builder. Therefore, hitherto, it has been performed to form the projecting angle of the wall by using a square bar (corner bead) made of metal or plastic. For example, a square bar that has been conventionally used has a Y-shaped cross-sectional shape, and the square bar is embedded in the projecting corner of the wall as shown in FIG. used. When forming the projecting angle of the cross-sectional structure shown in FIG. 6, first, the two blade portions of the square bar 9 having a Y-shaped cross-sectional shape are embedded in the column 6 of the wall. Fix the square metal 9 and the undercoat layer 10
After coating, the top coat layer 11 is coated in accordance with the straight line of the tip of the blade protruding outward, and finally the projecting angle is formed.

However, since such a square bar has almost no flexibility, when a corner angle of a wall of a three-story house is to be formed, a square bar having a length of about 9 m extends linearly. It is necessary, and a square bar of such a length is very difficult to handle. Further, if deformation or bending occurs when the square metal is embedded, there is a problem that the finally formed projected angle is not linear. Furthermore, as a square metal with improved handleability during transportation and installation, a product cut into a certain length has been used, but when such a square metal is connected and used, There is a drawback in that it is difficult to arrange all the plurality of square bars on a straight line.

As described above, hitherto, no material and method for forming the projecting angle which can easily form the projecting angle of the wall in a straight line have been proposed.

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems and provides a material and method for forming a projecting angle capable of easily forming a projecting angle of a wall in a straight line. This is an issue.

DISCLOSURE OF THE INVENTION The cord material for forming the projecting angle of a wall (corresponding to forming the projecting angle of the wall) of the present invention is a band-shaped mesh 2 and a cord without twist. 3 and the network 2
It is characterized in that the string 3 is bonded to one of the long sides. Further, in the above-mentioned cord material for forming the projecting angle of the wall, the notch 5 cut from the other long side of the net 2 is formed in the net 2 at regular intervals in the direction perpendicular to the string 3. It is also characterized by being provided with a space.

The present invention will be described below with reference to the drawings showing an example of the cord material for forming the projecting angle of the wall of the present invention. Figure 1 (a)
It is a perspective view which shows a preferable example of the string material for forming the projecting angle of the wall of the present invention, and FIG. 1B is a cross-sectional view taken along the line AB of the string material shown in FIG. As shown in FIG. 1, a cord material 1 for forming a projecting angle of a wall according to the present invention comprises a mesh 2 extending in a strip shape.
And the untwisted string 3, which is the net 2
The string 3 is adhered to one of the long sides by the adhesive layer 4 (see FIG. 1B). Such a cord material of the present invention has flexibility in a state before being used and is excellent in handleability.

The mesh 2 of the cord material 1 illustrated in FIG. 1 is provided with notches 5 at right angles to the cord 3 at regular intervals. , From the other long side where the string 3 is not adhered to the string 3 side.
Since the notch 5 is such that the net 2 is alternately embedded in both of the walls forming the projecting angle (see FIG. 2A), the wall forming the projecting angle is formed. When the net 2 is embedded in only one side, the cut 5 may not be provided. However, when the notch 5 is provided, as shown in FIG. 1A, it is necessary to make an uncut portion exist on the extension line of the notch 5 of the net 2. This is because without this portion, the linearity of the string 3 is impaired at the position where the notch 5 is provided when the string 3 is stretched as shown in FIG. 2A.

FIG. 2 (a) is a sectional view of FIG.
It is a perspective view which shows the state when the string material 1 shown by (a) is attached to the pillar 6 of a wall, and FIG. 2 (b) is a figure which shows the state in the cross section of (a). In addition, the upper end side and the lower end side of the string 3 are fixed to the mounting nail 7 by the mounting nail 7 in a state in which a constant tension is applied, as shown in FIG. Shows a typical shape of the mounting nail 7 used for fixing the string 3. The tip of the attachment nail 7 is bifurcated, and the string 3 is stretched with a constant tension through the recessed portion of the bifurcated portion.
However, the method for fixing the cord 1 of the present invention is not limited to that shown in FIG.

The mesh 2 in the cord 1 of the present invention is not particularly limited, but to some extent elasticity (softness) so as to be able to cope with the tension applied to the cord 3 during use.
Those having plastics are preferable, and those made of plastic, such as commercially available nylon nets and nets made of cotton thread, are particularly preferable. Of course, in the present invention, the wire 2 may be a general wire lath (used for the mortar coating base).

On the other hand, the cord 3 may be any one that is unlikely to be twisted, but particularly preferable is a braided cord formed by knitting a plurality of yarns, or a core yarn is inserted into the hollow portion of the hollow yarn. For example, a string having a modified structure is used. In the latter string, when the tension is applied to the core yarn, the hollow fiber on the outside becomes linear. Also, the thickness of the string 3 in the present invention is not particularly limited and may be appropriately selected according to the length of the corner of the wall, but in the case of an ordinary two-story or three-story house In the string material used for, the thickness of the string 3 is about 5 m.
It is about m. In the present invention, the reason why the cord 3 is limited to the one that is less likely to be twisted is that when the cord is twisted, the entire cord does not become a straight line, and when the cord is bent in this way, the wall is exposed. This is because the corner angle cannot be formed linearly. In the present invention, the string 3 may be made of an elastic material such as a rubber string.

When the cord material 1 of the present invention is produced, the net 2 and the cord 3 are prepared, and tension is applied to both ends while the cord 3 is not twisted, and the cord 3 is bonded in a straight line. Apply adhesive to the surface area. Then, one long side of the net 2 is adhered to the portion where the adhesive is applied. The adhesive used at this time may be appropriately selected depending on the materials of the net 2 and the string 3. The notch 5 is generally provided after the net 2 and the string 3 are bonded, but the notch 5 may be provided in the net 2 before the bonding. In the thus-produced cord material 1 of the present invention, since the cord 3 is not twisted, when tension is applied to both ends of the cord 3, the cord 3 becomes linear.

Next, the method of the present invention for forming the projecting angle of the wall by using the above-mentioned cord material for forming the projecting angle of the wall will be described. The method of forming the projecting angle of the wall according to the present invention includes the following steps A to C, ie, step A: a projecting corner formed by adhering a twist-free string 3 to one long side of the mesh 2 extending in a strip shape. Fixing both ends of the cord 3 of the horn forming cord 1 under a constant tension above and below the building where the projecting angle is to be formed, Step B: Applying a fixative to the cord 3 The step of forming the cord 3 into a linearly extending rod-shaped body, and Step C: applying a wall material according to the rod-shaped cord 3 to form a projecting angle. To do.

That is, in the method of the present invention, the string 3 is stretched in a straight line in the step A (see FIG. 2),
In step B, by applying a fixing agent to the string 3 and solidifying the string 3, the string 3 becomes inflexible and becomes a single linear rod-shaped body. The fixing agent that can be used in the present invention is not particularly limited, and commercially available resin-containing products such as cation tight can be widely used. Then, in the final step C, as shown in FIG. 5, by applying the wall material 8 so that the string 3 is located at the projecting angle, a beautiful linear projecting angle can be formed.

When the method of the present invention is used, the projecting angle of a three-story house can be formed relatively easily, and in this case, the above-mentioned cord material having a length of about 9 m is used. However, it can be applied to a building with a height higher than this. It should be noted that the method of the present invention is particularly suitable for forming parallel projection angles that are parallel to each other. Therefore, when the method of the present invention is used to form the corner portions of a prismatic column, the width of the column can be very easily obtained. The dimensions can be matched. Further, it is also useful for forming a surface to be tiled.

Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.

Example A knitting cord having a thickness of about 4 mm and a length of about 10 m, and a mesh extending in a band shape having a mesh size of about 5 mm square (width about 5 mm
5 mm, length about 10 m, made of plastic) was prepared, and tension was applied to both ends while preventing the twisting of the braid, and the braid was stretched linearly. Then, a commercially available adhesive was applied to the string stretched in a straight line, and one long side of the net was adhered to the portion where the adhesive was applied. Thereafter, the mesh portion is provided with a notch having a depth of about 40 mm at intervals of about 20 cm, and the projected corner of the wall of the present invention having the appearance and cross-sectional structure shown in FIGS. 1 (a) and 1 (b). A horn-forming string material was produced. On the extension line of the cut of the cord material, the uncut portion of the net remains with a width of about 15 mm.

As shown in FIGS. 2 and 3, the string material thus produced is attached to a pillar of a wall of a three-story wooden house, and a wall material (mortar) is applied from above the pillar. When the projecting angle of the cross-sectional structure shown in FIG. 5 was formed, it was possible to form a straight projecting angle without the individual difference of the builder.
