[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mortar wall embedding ruler used for coating mortar on the vertical and horizontal outer surfaces of a corner of a building.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional embedded ruler for mortar walls. Reference numeral 10 is a vertical strip that abuts a vertical outer surface of a corner of a building, and has a plurality of lateral projections 11 and through holes 12 provided on the inner surface. A horizontal strip 13 that is bent horizontally inward from the lower end of the vertical strip 10 is integrally formed. A groove 16 is formed by bending downward from the middle portion and further horizontally inward, and an L-shaped skirt plate 17 is integrally formed by projecting outward from the tip of the groove 16.

In use, as shown in FIG. 6, the vertical strip 10 is brought into contact with the vertical outer surface 18a of the corner of the building, and the horizontal strip 1
3 is brought into contact with the horizontal outer surface 18b of the corner 18, and the vertical mortar wall 19 is applied to the tip of the skirt plate 17 and the horizontal mortar wall 20 is applied to the lower face of the skirt plate 17.

[0004]

In the prior art described above, when the mortar dries in 2 to 4 weeks, the vertical mortar wall 19 contracts and deforms in the direction of arrow A as shown in FIG. The contraction force of the vertical mortar wall 19 is better than the adhesion force attached to the horizontal outer surface 18b of the corner 18, and the horizontal strip 13 is curved downward as shown by B and peels off.
There was a problem that a crack was generated in the part.

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above problems, and from the vicinity of the base of a horizontal strip that bends inwardly horizontally from the lower end of a vertical strip that abuts a corner vertical outer surface of a building. The groove is formed by bending downward and horizontally inward, and forming an L-shaped skirt plate outward from the tip of the groove to integrally form the tip of the horizontal strip at a considerable distance from the groove. The vertical strips and the horizontal strips are positioned forward and a slit for cutting is provided at the tip of the groove of the horizontal strip so that the horizontal strips can be cut and separated at the slits to be used for long / short two. The plate is characterized in that a plurality of ridges and through holes are formed.

[0006]

Example 1 is a vertical strip that abuts a vertical outer surface 18a of a corner 18 of a building, which is bent downward from the vicinity of the base of a horizontal strip 2 which is bent inwardly from the lower end thereof, and is horizontally inward. To form a groove portion 3, and an L-shaped skirt plate 4 is projected outward from the tip of the groove portion 3 to be integrally formed, and the tip end position of the horizontal strip plate 2 is positioned a considerable distance forward of the groove portion 3, A slit 5 for cutting is provided at the tip of the groove 3 of the horizontal strip 2, and the horizontal strip 2 is cut and separated at the position of the slit 5 so that it can be used in a long / short 2 manner. And a plurality of ridges 6, 7 and through holes 8, respectively on the back surface of the horizontal strip 2.
9 is formed. No ridge or through hole is provided inside the slit 5 of the horizontal strip 2.

FIG. 3 shows a first use example of the present invention. Abut the vertical strip 1 on the vertical outer surface 18a of the corner 18 of the building,
The horizontal strip 2 is brought into contact with the horizontal outer surface 18b as it is without being cut from the slit 5, and the vertical mortar wall 21 is aligned with the tip of the skirt plate 4 and the horizontal mortar wall 22 is aligned with the lower surface of the skirt plate 4. Apply.

FIG. 4 shows a second use example of the present invention. The horizontal strip 2 is cut and separated from the slit 5 to form a short horizontal strip 2 ', and the vertical strip 1 is used as the vertical outer surface 18a of the corner 18 of the building.
Then, the horizontal strip 2'is brought into contact with the horizontal outer surface 18b, and the vertical mortar wall 21 is applied to match the tip of the skirt plate 4.

In the former case, since the horizontal strip 2 is sufficiently longer than the conventional product, the vertical mortar wall 21 dries in 2 to 4 weeks, and even if it contracts and deforms, the horizontal strip 21 is peeled off or cracked as in the conventional case. Does not occur. In the latter case, the groove can be exposed and used for draining.

[0010]

EFFECTS OF THE INVENTION According to the present invention, the vertical strip that abuts the vertical outer surface of the corner of the building is bent inward from the lower end of the horizontal strip bent downward from the vicinity of the base of the horizontal strip, and further bent horizontally inward. A groove portion is formed, and an L-shaped skirt plate is projected outward from the tip of the groove portion so as to be integrally formed, and the tip position of the horizontal strip is positioned a considerable distance forward of the groove portion. A slit for cutting is provided on the horizontal strip so that the horizontal strip can be cut and separated at the slit position so that it can be used in a long and short manner. A plurality of ridges and through holes are formed in the vertical strip and the horizontal strip. Therefore, it is possible to prevent the horizontal strip from peeling off or cracks in the horizontal mortar wall due to the drying shrinkage of the vertical mortar wall by using the horizontal strip for a long time, and also to prevent the horizontal strip from cracking in the intermediate slit part. It can also be cut and shortened and the groove part exposed. That.

Claims (1)

(57) [Scope of utility model registration request] 1. A vertical strip that abuts against a vertical outer surface of a corner of a building is bent downward from the vicinity of the base of a horizontal strip that is horizontally bent inward from the lower end, and is further bent horizontally inward to form a groove. An L-shaped skirt plate is projected outward from the tip of the groove portion to be integrally formed, and the tip position of the horizontal strip is positioned a considerable distance forward of the groove portion, and a cutting slit is provided at the groove tip position of the horizontal strip plate. It is characterized in that the horizontal strip is cut and separated at the slit position so that it can be used in two different lengths and shorts, and a plurality of ridges and through holes are formed in the vertical strip and the horizontal strip.
