いる。Conventional technology and its problems Conventionally, the corner edge surface of the wall corner has a doglegged or Y-shaped cross section.
A commonly used method is to attach embedded rulers shaped like letters, etc., and finish the wall with mortar according to the height of the ruler plate that extends forward from the corner of the wall. Although this ruler has the advantage of being able to draw straight lines and right angles at wall corners beautifully and quickly, there are many cases where the mortar breaks up along the ridge lines of wall corners. This has been pointed out by people in the field.

が肌分れ界面となつてその両側面のモルタルが収
縮硬化し、該肌分れがモルタルが最も薄く塗着さ
れている定規板先端縁において顕著に現れること
に起因している。 This is because a ruler plate is interposed at the corner of the mortar, and this becomes a skin interface, causing the mortar on both sides to shrink and harden. This is due to the fact that it appears conspicuously.

のである。Purpose of the invention The present invention was devised to solve the above-mentioned drawbacks, and the purpose of this invention is to make the mounting plate of the ruler plate exhibit a mortar retaining effect, so that the mortar layer existing on the mortar surface escapes from the ruler plate when the mortar hardens. It is an object of the present invention to provide an embedded ruler that satisfactorily prevents shrinkage in this direction and prevents problems such as separation and cracking of the mortar layer with the ruler plate as an interface as much as possible.

ように構成したものである。Structure of the invention In order to achieve the above object, the shape of the mounting plate is formed such that the plate thickness in the transverse direction gradually increases from the ruler plate side end to the other end, so that the cross section has a substantially wedge shape, Therefore, the embedded ruler is configured to have a retaining effect on the mortar layer on the surface of the mounting plate.

実施例 以下本考案の実施例を図面に基いて詳述する。Example Embodiments of the present invention will be described in detail below with reference to the drawings.

る。 FIG. 1 shows a first embodiment, and 1 indicates an embedded ruler. The embedded ruler 1 has mounting plates 2 and 3 attached along the length of a corner edge surface forming a wall corner.
and a ruler plate 4 which is arranged in series so as to extend over the length of the mounting plates 2 and 3 toward the front of the corner of the wall,
The mounting plates 2 and 3 are bent at an angle substantially in line with the corner of the wall, and the ruler plate protrudes from the bent portion, and are integrally molded to have a substantially Y-shape in cross-section.

る。 The present invention provides an embedded ruler having the above structure, in which mortar joint holes 6 are punched in the mounting plates 2, 3 or the ruler plate 4, and mortar joint ribs 7 are formed on the surface of the mounting plate. As shown in Fig. 2, the plate thickness is gradually increased so that the edge on the side of the ruler plate becomes the thinner end 2a, 3a, and the other end becomes the thicker end 2b, 3b, so that it has a wedge shape when viewed in cross section. This is what I did.

塗布する。 As shown in FIG. 3, the embedded ruler 1 thus formed is pressed against the corner of the wall while holding mortar inside the mounting plates 2 and 3.
Attach the ruler plate to the corner edge surface and make the ruler plate extend toward the front of the wall corner. After that, mortar 5 is applied according to the height of the ruler plate.

の引き留め効果を発揮する。 As can be understood from FIG. 3, each mounting plate 2, 3 is embedded within the mortar so that it becomes thinner at the corner of the wall and becomes thicker in the direction away from the corner. As a result, the mortar layer 5 existing on the surfaces of the mounting plates 2 and 3 conversely runs along the slope of the mounting plates 2 and 3 from the free end side (thick end portions 2b and 3b side) to the mounting base side of the ruler plate 4. It tends to be pushed toward (thin end portion sides 2a, 3a). This exerts a retaining effect on the mortar.

よつて可及的に抑止される。 That is, when the mortar 5 hardens and contracts, it tends to move away from the ruler plate 4 as described above. This movement is suppressed as much as possible by the wedge-shaped shape of the mounting plates 2, 3.

いてより高める結果となる。 FIG. 4 shows a second embodiment in which the present invention is applied to an embedded ruler plate 1 that does not include one of the mounting plates of the Y-shaped embedded ruler. That is, the identification plate 1 includes a single mounting plate 2 attached along the length of a corner edge surface forming a wall corner, and a single mounting plate 2 extending longitudinally from the edge of the mounting plate 2 toward the front of the wall corner. It consists of ruler plates 4 that are arranged in a row so as to extend outward, and has a substantially doglegged shape when viewed as a whole. It is characterized in that it has a wedge shape and gradually increases in thickness so that the other end becomes a thin end 2b. In this case, it goes without saying that the mortar joint holes 6 and the joint ribs 7 may be used together. Also in the ruler plate 1, escape of the mortar on at least one side thereof (escaping from the tip edge of the ruler plate) is effectively prevented, and separation of the skin using the ruler plate 4 as an interface is effectively prevented. still,
In the first embodiment and the second embodiment, by using the mortar coupling hole 6 and the coupling rib 7 in combination, the rib is similarly inclined along the width direction of the mounting plate, and the mounting plate of the coupling hole 6 is also tilted. The depth gradually increases toward the thicker side, resulting in a higher mortar retention force at the end of the mounting plate.

助長等の問題点を有効に解消する。Effects of the Invention As detailed above, the wall finishing embedded ruler of the present invention gradually increases the thickness of the mounting plate in the width direction of the wall from one end of the ruler plate to the other end, forming a wedge shape. Therefore, it is possible to effectively prevent skin separation and exposure of the ruler plate due to mortar shrinkage during the curing process after applying the mortar, thereby preventing loss of aesthetic appearance. It also effectively eliminates problems such as the occurrence of cracks caused by skin separation and the promotion of natural deterioration.
