Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a slit ruler that is used to easily and beautifully finish the slit edges of columns in plastered walls of buildings.

(Prior art and its problems) During the process of undercoating and topcoating in wall painting work for buildings, adhesion of wall materials caused contamination, and cleaning with a water brush was particularly necessary to finish the areas where the pillars had been scattered. In particular, wall materials such as gypsum plaster are used in the undercoating process, and since the coating is thick, there is a lot of wall material adhesion, which can easily lead to contamination. Therefore, if the pillars are left as they are, stains will form on the pillars, and the adhered wall material must be removed many times with a water brush, making cleaning time consuming.

In addition, the scattering dimensions of the pillars had to be constant, and it required skill in plastering techniques to even out the coating thickness.
It had the drawback of poor efficiency.

(Purpose of the invention) Therefore, the present invention prevents the adhesion of wall materials from contamination during the undercoating process, which accounts for most of the contamination of the scattered parts of pillars, and also makes it extremely easy to set the coating thickness of wall materials. To provide a dusting ruler capable of finishing a dusting part with good workability and forming a beautiful shape.

(Structure of the invention) The scattering ruler has a ruler member having a substantially inverted U-shaped cross section with a long groove provided between mounting plates arranged in parallel to a ruler plate, the ends of which are connected, and the other end opened, and a ruler member inserted into the entire length of the long groove. The protective member is made up of a flat plate-shaped protective member that can be removed from the long groove.

(Example) Next, an example of the present invention will be explained based on the drawings.
The scattering ruler 1 consists of a ruler member 2 and a protection member 3,
The ruler member is made of synthetic resin and is connected at the end to form a long groove 6 between the ruler plate 4 and the mounting plate 5.
It is a long body with a generally inverted U-shaped cross section with the other end open. And double-sided adhesive tape 7 is attached to the outer surface of the mounting plate 5.
is pasted to make temporary fixing to the side of the column easier. Further, the ruler plate 4 has a protrusion 8 extending outward at a right angle to the opening end thereof, and this makes the contact with the iron good and makes it easy to apply the wall material to a constant thickness. Further, the surface of the ruler plate may be provided with a large number of small protrusions 9 in order to improve the integration of the wall material by coating.

On the other hand, the protection member 3 is a band plate with one end inserted into the long groove 6 of the ruler member, and has a protruding surface 10 that protrudes from the long groove insertion portion, and this serves as a protection plate for preventing wall material from adhering. This protective member is made of synthetic resin or paper, is inserted into the long groove, and can be removed after the undercoating process is completed. Therefore, a soft protrusion 11 is provided inside the long groove in order to absorb accuracy errors in the thickness of the protective member and to insert and hold the protective member into the long groove with a certain degree of resistance. Further, in order to make it easier to remove the protective member, the protrusion surface 10 may be provided with a projection 12 that engages the fingertip.

In order to finish the splattered area using this splatter ruler, first, as shown in FIG. ). 15 is plasterboard. When fixing the scattering ruler mentioned above, in order to keep the scattering dimension T of the pillar constant, use ink to position it.
Usually, the plasterboard 15 is installed by calculating the coating thickness of the wall material, so the plasterboard is attached by abutting the surface of the plasterboard with a scattering ruler having a width corresponding to the predetermined coating thickness dimension.

After the undercoat 14 has dried, the protective member 3 is removed and a topcoat 16 is applied. (Fig. 4) As the wall material for this top coat, a common fiber-based wall material is often used.

In addition, when applying the topcoat after the protective member 3 has been removed, since the above-mentioned fiber-based wall material is often used for the topcoat and the coating thickness is thin and in a small amount, it may not adhere to the scattered areas. is extremely small, and the cleaning effort is greatly reduced.

(Effect of the invention) Since this is a cut-off ruler in which a flat protective member is inserted into the long groove of a ruler member having a roughly inverted U-shaped cross section with a long groove provided between the mounting plates arranged parallel to the ruler plate, the tip of the ruler plate The wall material can be applied in a straight line with a constant thickness, making it easy to create a beautiful wall surface. Also, the protection member prevents the adhesion of the undercoat wall material to the scattered parts of the pillars. This eliminates the need for cleaning as required in the past, and therefore the workability is extremely high.

Moreover, the topcoat wall material has the effect of digging into the long grooves after the protective member has been removed near the pillars, that is, at the corners of the wall, and the adhesion of the wall material around the pillars is extremely strong, resulting in a gap between the pillars and the wall. It has the characteristic that it can prevent the phenomenon of so-called dispersion, which occurs when gaps are formed between the layers.
