Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embedded ruler for corner finishing in plastering work.

[0002]

2. Description of the Related Art Conventionally, as an embedding ruler for corner finishing of a coated wall, as represented by Japanese Examined Patent Publication No. 57-21625, the length of a mounting plate portion to be mounted along a corner edge surface of a wall of a vehicle body. There is known an embedded ruler in which a ruler plate portion is bent and formed in a dogleg shape at one side edge in a direction at a constant inclination angle. In this embedded ruler, a mounting plate portion is attached to a corner edge surface of a wall so that a ruler plate portion bent and formed on the mounting plate portion is obliquely projected from the corner portion, and the edge of the projected ruler plate portion is protruded. By applying the standard coating material, the entire surface is embedded in the coating material while the corner finishing is performed.

[0003]

When a corner of a wall is to be finished by using this type of embedded ruler, the ruler should be preliminarily set on the body surface (the corner edge of the wall) before the wall coating of the coating material such as mortar. However, it is difficult to change and adjust the amount of protrusion of the edge of the ruler plate whose angle is fixed in the structure where the mounting plate is faced to the corner edge surface as described above. As a result, there is a problem in that it is difficult to properly align the edge of the ruler plate with the level thread accurately.For example, if the mounting plate of the embedded ruler is slid in parallel along the edge of the wall. Even with the angle of the ruler plate fixed, the overhanging amount changes only in the direction of the one corner edge surface, and the one corner edge surface side and the other corner edge surface side depending on the construction site. The coating thickness of both could not be changed.

Therefore, there is an inconvenience that plural kinds of rulers must be prepared in order to cope with the change of the coating thickness.

[0005]

[Means for Solving Problems] Along the edge portion of the corner of the wall, one end is projected to the front of the corner, the coating material is applied using the protruding portion as a ruler portion, and the whole is placed in the coating material. In the embedded ruler to be embedded, the entire embedded ruler is rolled on the attachment surface to adjust the opening angle between the ruler portion and the edge portion of the corner portion. Therefore, the embedded ruler has a plurality of wall abutting surfaces with respect to the edge surfaces of the corners, and the opening angle is adjusted by selecting the wall abutting surfaces.

[0006]

[Function] The entire embedded ruler is slid to one side along the one corner edge surface attached thereto, and the whole is rolled on the one corner edge surface to set the wall contact position. By adjusting the opening angle between the corner edge surface and the ruler section, the amount of protrusion of the ruler section in one corner edge surface direction and the other corner edge surface direction can be adjusted freely and easily, and the coating thickness can be adjusted. Can respond effectively to changes. Further, by the above operation, the work of matching the edge of the ruler portion with the level yarn can be performed without difficulty.

In addition to the adjustment of the opening angles α1 and α2, the entire embedded ruler 2 slides on one corner edge surface 1 toward the other corner edge surface 1'by an appropriate amount to project in the same direction. By adjusting, the amount of protrusion of the end of the embedded ruler 2b with respect to the edge surfaces 1, 1'of both corners can be freely changed and adjusted.

Thus, as shown in FIGS. 2 and 3, the application thickness of mortar or the like on both surfaces of the projected corner wall can be changed at any time depending on the site of implementation. Further, by the above adjustment, the edge of the ruler portion 2b can be accurately and easily matched with the level yarn, and the accuracy of the coating thickness can be properly adjusted.

The embedded ruler 2 is constructed so that a ruler portion 2b 'is formed at the end opposite to the ruler portion 2b so that the embedded ruler 2 can be reversed and used without directivity. The embedded ruler is nailed to the corner edge surface 1 or is adhered to the corner edge surface 1 via a mortar or an adhesive.

Further, as shown in FIGS. 4A and 4B, a large number of coating material coupling holes 2c which are open on the attachment surface 2a and the surface (outer surface) opposite to the attachment surface 2a are provided, and a ruler is added together with the coupling holes 2c. A groove for coating the material to be coated, preferably a dovetail groove 2d, is provided on the installation surface 2a or the outer surface in parallel in the lateral direction so as to extend in the ruler longitudinal direction, or the ruler-attached surface 2a or the outer surface.

[0022]

As described above, according to the present invention, the entire embedded ruler rolls at the corner edge surface of one wall on the attachment surface thereof so that the ruler portion and the corner edge surface are formed. Since the configuration is such that the opening angle is adjusted, the amount of protrusion of the edge of the ruler portion with respect to the edge surfaces of both corners can be freely and easily changed by simply finely sliding to one side together with the adjustment of the opening angle. Therefore, it is possible to effectively cope with the change of the thickness of the coating material.

Further, the end portion of the ruler portion can be easily matched with the level yarn, so that the coating material can be applied properly and uniformly with reference to the end edge of the ruler portion.

Therefore, since the thickness of the coating material can be changed with one type of embedding ruler as described above, it is possible to effectively eliminate the inconvenience of preparing a plurality of embedding rules as in the conventional case, depending on the construction site. It is possible to finish the corner of the wall.
