Description

[Detailed Description of the Invention] The present invention relates to an embedded ruler used by plasterers to draw beautiful right angles and straight lines with good workability when applying finishing material to the walls of buildings.

In plastering work using this kind of embedded ruler, first, the ruler is temporarily attached with mortar, and then the ruler is moved etc. to adjust the protrusion and protruding position of the ruler board (adjustment of thickness and edge). )
This adjustment work is extremely important in order to perform so-called skilled plastering work.

However, the so-called Y-shaped ruler, such as the conventionally known Utility Model No. 98 of 1973, has the advantage of being strong, preventing bending, and being able to be stably attached to a wall, but on the other hand, because the two mounting plates are of equal length. , it is possible to increase the thickness of one side by floating one mounting plate on one side of the corner with mortar at a specified height, but then move this one mounting plate sideways and attach it to the other side. When trying to increase the thickness by moving the mounting plate closer to or away from the other corner creepage, if you try to move it in the direction toward it, it will always interfere with the corner creepage and cannot be moved, making adjustment impossible.

This is the biggest drawback of the Y-shaped ruler plate, which has equal length mounting plates, and is a problem for craftsmen in the field.

In addition, as seen in Utility Model No. 14729/1983, the wall warming board and the ruler board are simply formed into a dogleg shape, with the above-mentioned adjustment of the wall coating right bank and the corner edge. Although it has the advantage of being able to freely adjust its positioning, it has the disadvantage that it is weak and easily bends when it is made long, and this disadvantage becomes even more pronounced when using a perforated plate structure that is essential for bonding with finishing materials. This becomes an obstacle to workability and straight line alignment.

The embedded ruler of the present invention was developed against the background of the current situation, and it solves the problem of the bending of the doglegged embedded ruler mentioned above and the above-mentioned Y.
We would like to provide an embedded ruler that simultaneously solves the problem of the inability to adjust the thickness of the square shaped embedded ruler, combines the advantages of both rulers, and also solves the problem of peeling, which is essential for practical use. It is something to do.

The drawings show one embodiment thereof. Figure 1A shows the main body of the embedded ruler which is integrally molded, and Figure B shows an example in which the plate surface of the ruler body has finishing material joining holes and dovetail-shaped finishing material joining ribs. show.

In the figure, reference numerals 1 and 6 indicate first and second mounting plates, and as shown, the mounting plates 1 and 6 are connected to each other at a bending angle that is approximately in line with the wall portion.

2 and 3 show the mounting plates 1 and 6 bent at 90' and attached to the wall part 3.

Reference numeral 2 denotes a ruler plate that is connected to the bending portion 5 of the mounting plates 1 and 6 so as to extend forward from the corner of the wall. The main body of the ruler is constructed by integrally molding the connecting points with synthetic resin.

Figures 2 and 3 show the ruler plate 2 attached to the mounting plates 1 and 6.
The case is shown in which the ruler plate 2 is extended at an angle of 135° and the finishing material 4 is applied to the left and right sides of the ruler plate 2 as a reference.

Reference numerals 7 and 9 indicate coupling holes for the finishing material 4, which are formed in large numbers through each plate surface of the ruler body, and 8 indicate ribs for coupling the finishing material 4 that protrude from the front and back sides of the plate surface of the ruler body, preferably. In order to enhance the bonding effect, the cross-sectional shape is dovetail-shaped as shown in the figure.

FIG. 1B illustrates a case where the dovetail-shaped finishing material joining rib 8 is integrally formed on the front and back surfaces of the mounting plate 6.

The coupling holes 7 and 9 may be circular, triangular, square, or snotted, or may be arbitrarily selected depending on the implementation.

Further, as shown in the figure, the first mounting plate 1 is made wide at its short side to ensure a mortar attachment margin, while the second mounting plate 6 is made sufficiently narrow at its short side.

Preferably, as shown in the figure, the width of the short side of the second mounting plate 6 is set to be less than the width of the short side of the first mounting plate 1.

As shown in FIG. 3, as shown in FIG. It is possible to apply the finishing material based on the ruler plate 2 which is projected toward the front of the section.

Furthermore, according to the structure of this ruler material, construction as shown in FIGS. 4A and 4B is also possible.

In other words, the first mounting plate 1 is raised to a predetermined height on one corner of the wall section using mortar 4', and while increasing the thickness of one corner, the second mounting plate 6 on the other side is raised. The first mounting plate 1 is moved from the side of the other corner as shown by the imaginary line so that it does not hang on the corner, and the first mounting plate 1 is then laterally shifted to increase the thickness of the side of the other corner.

As mentioned above, while securing the required mortar attachment margin with the medium-wide first mounting plate 1, the thickness is increased by making the second mounting plate 6 narrower than the majority of the first mounting plate 1.
The positioning of the corner edges can be adjusted.

For example, if the short side of the first mounting plate 1 is set to around 30 mm, the second mounting plate 6 may be 7 mm long, so that the length of the second mounting plate 6 is 1Q mm.

In addition, Fig. 4 shows the rib 8 and the coupling hole 7 for ease of explanation.
, 9 are omitted.

As described above, the second mounting plate 6 solves the problem of bending and bending of the ruler material, and depending on how it is used, it becomes possible to perform thickening operations and positioning of corner edges, which are highly required on site.

Also, due to the joint holes 7, 9 and the rib 8, the ruler and the finishing material 4
Significantly improves the bonding effect with

By doing the above, it is possible to simultaneously achieve strength and strengthen the bonding force to the finishing material, and as a result, the straightness of the ruler at the site makes work easier, and the falling of the coating material when applying the finishing material,
The problem of peeling has been completely eliminated, and it has become possible to quickly and beautifully thicken and straighten corners.
