Description

[Detailed description of the invention] This invention is a corner finish that is used embedded in the wall finishing material when applying finishing materials such as mortar, plaster, and plaster to the wall of a building using a plastering trowel. This invention relates to a built-in ruler, which has been improved so that it can be mass-produced at a significantly lower cost as a whole, and its coloring is compatible with the wall finishing material, so that it does not give a sense of discomfort to the external appearance of the building. .

Hereinafter, the specific structure of the present invention will be described in detail based on the illustrated embodiment. Figures 1 to 3 show basic examples of the embedded ruler, and the ruler G maintains a constant angle α of about 90 degrees. A pair of two substrates 10 intersecting each other
and one corner cutting branch plate 11 that continuously and integrally protrudes outward from the intersection, and has an approximately Y-shaped cross section as a whole. β
represents a certain angle at which the branch plate 11 and the substrate 10 intersect, which is approximately 135 degrees.

In that case, the protruding height H of the branch plate 11 is determined appropriately, and the cross-sectional shape of the protruding tip, which is the exposed part a to the outside world when using the ruler G, is shaped into a wedge-shaped sharp shape as shown in the figure. For example, various shapes such as a semicircle or an inverted triangle as shown in Fig. 5,
It can be made thicker. Further, the substrate 10 has a large number of through holes 12 scattered throughout it.
and a large number of protrusions 1 running parallel to the longitudinal direction.
3 is disposed so that it is strongly bonded to the wall finishing material M such as mortar or plaster. If the protrusion height H of the branch plate 11 is considerably high, the branch plate 11 is also provided with the through holes 12 and ridges 13 as described above. In any case, after the ruler G itself is extruded, the through hole 12 is punched out using a suitable blade.

In the extrusion molding of the ruler G, a thermoplastic synthetic resin such as hard vinyl chloride is used. Regarding the part a exposed to the outside world in 11, it is determined to be white or other pale or bright color from a good material (new material) of a certain synthetic resin, and on the other hand, it is buried in wall finishing material M such as mortar or plaster. The remaining majority part b of the branch board 11 and the entire part c of the substrate 10, which are to be painted, are made of the same synthetic resin waste and are colored dark gray or other deep or dark colors, thereby creating a so-called two-tone color. Embedded Ruler G is a completely unique product with a unique design.

In other words, as outlined in FIG. 4, the waste material of synthetic resin products is effectively utilized and recycled and melted to form the hopper 15 of the extruder 14.
The screw 16 is used to push a good material (new material) of the same synthetic resin into the mold 17 from one direction of arrow X. By placing the two materials in a divided state with a relative contrast of light and shade or light and dark, the two materials are simultaneously extruded and then sized.

In this regard, in the basic example shown in Figs. 1 to 3, the approximately triangular cross-section portion corresponding to about one-third of the protruding height H of the branch plate 11 is made of the above-mentioned good quality synthetic resin material and is colored light or bright. Furthermore, in the modification shown in FIG. 5, the thick portion of the branch plate 11 having a substantially semicircular cross section is also extruded from a good synthetic resin material in a light or bright color. Furthermore, in the illustrated embodiment, the ruler G having a generally Y-shaped cross section as a whole has been described;
The present invention can be applied in exactly the same way to rulers in which one or more rulers protrude while maintaining a certain angle intersecting relationship, such as approximately L-shaped, U-shaped, horizontal F-shaped cross sections, and other rulers. . Further, in the illustrated embodiment, the ruler G is used in a manner in which a portion of the branch plate 11 is exposed to the outside world.
However, in the case where a part of the substrate 10 is exposed to the outside world, or where the substrate 10 and the branch plate 11 are
It goes without saying that even if a portion of both the material and the material is exposed to the outside world, such a portion can be made of a good quality synthetic resin and colored in a light or light color in the same way as described above.

When finishing the corners of walls in buildings using the embedded ruler G configured as described above, first apply mortar to the corners of the wall base Z made of concrete etc., as shown in Figure 2. A wall surface finishing material M such as or plaster is applied, and both substrates 10 of the ruler G are pressed and fixed thereon. At this time, the finishing material M flows out from the through hole 12 opened in the ruler G, so that the ruler G is temporarily held. Then, before the finishing material M hardens, a finishing material M of the same quality is applied uniformly along the branch plate 11 of the ruler G, etc., as shown in FIG. As a result, beautiful wall corners with a uniform coating can be completed efficiently without requiring any skilled work. In this state, the protruding tips of the branch boards 11 will be exposed as pale or bright colors, providing a suitable appearance that is compatible with the wall surface finishing material M.

As described above, the present invention includes one or a plurality of substrates 10 that intersect at a certain angle, and the substrates 10.
The substrate 10 is
As an embedded ruler G made of extruded synthetic resin with one or more branch plates 11 continuously and integrally protruding from the substrate 10 and/or the branch plates 11, the part a exposed to the outside, A light or bright color is determined by using a good quality synthetic resin material such as hard vinyl chloride, while all remaining embedded parts b and c of the substrate 10 and branch board 11 are made of a dark color from waste material of the same synthetic resin. Alternatively, by setting the ruler G to a dark color, the ruler G as a whole is molded into a different colored section at the same time, allowing for mass production at an extremely low cost while making effective use of the waste materials mentioned above. Alternatively, by using a light color, it is possible to obtain a suitable external appearance that blends in with the wall surface finishing material M without making it generally known that the ruler G is embedded. In addition, since the good material and the waste material are made of the same synthetic resin, they have excellent compatibility as an extrusion molded product, and there is no fear of breakage at the boundary between the two materials, making it suitable for practical use.
It should be noted that since the above-mentioned shading or brightness is relative between good wood and waste wood, it goes without saying that various colors that are compatible with the wall surface finishing material M can be used as the specific designated color.
