Description

[Detailed description of the invention] The present invention is a method for creating an uneven three-dimensional decorative pattern on the surface of finished members such as interior and exterior walls, ceilings, floors, etc. This invention relates to a pattern creation tool.

In recent years, with the improvement of cultural life, various ideas and innovations have been made in the housing sector.

Among these, in the field of finishing walls, etc., decorative wall surfaces with excellent three-dimensional design taste due to unevenness, etc. are being preferred along with diversification of colors.

For this purpose, the surface of the wall material, which has been painted to the required thickness on the concrete foundation wall surface by spraying or troweling, is directly pressed up and down with a roller, etc. with a required patterned surface formed on the outer periphery. Generally, the pattern is leveled and transferred in directions such as left and right to create a three-dimensional pattern.

However, with conventional rollers, the outer cylindrical part of the roller, which has an uneven pattern, is simply given some flexibility, so if the surface of the wall material has unevenness, the uneven pattern that is embossed will be distorted. It was not formed beautifully and the pattern was often very irregular.

In particular, the embossed pattern may not appear at the boundary between the uneven part and the flat part, that is, at the hem of the uneven part, and it is necessary to repair it many times, which is very troublesome and reduces work efficiency. I will be inviting you.

The purpose of the present invention is to provide a molding tool that can be reliably pressed and molded even if there are some irregularities on the wall surface, etc., and is also larger than conventional molding tools.

Hereinafter, embodiments of the present invention will be described based on the drawings.

1 is a U-shaped frame made of a suitable material;
A handle 2 is fitted in the center of a, and both support frames 1b and l
A forming roller 3 is rotatably supported between the tips of b via a support shaft 4 that is removably inserted and suspended horizontally.

This forming roller 3 is composed of three layers: a cylindrical part 3a made of metal or the like, and a thickness of approximately 39 mm.
For example, the middle cylinder part 3b is made of a soft material such as sponge or entangled fibers, and the same or different soft material is slightly harder than the middle cylinder part 3b and has an appropriate pattern 5 on the outer peripheral surface. It consists of an outer cylindrical portion 3C.

The foreign material may be any material as long as it is porous and has open cells, and when the outer cylindrical portion 3C is made of a sponge material, it is preferably one with a foaming ratio of 1 to 5 times, preferably 2 to 4 times.
twice is optimal.

If this member is used, if the middle cylinder part 3b etc. is impregnated with light oil or the like as a mold release agent, the iron agent will be released from the surface of the forming roller 3 through the open air bubbles in the middle cylinder part 3b and the outer cylinder part 3C. is infiltrated and the mold release property between the coating material side and the molded part side is good, and even if the wall surface such as the coating material is a highly viscous material, the mold release is good and the molded pattern is prevented from collapsing. can.

In addition, when the foaming ratio is 2 to 4 times, it is easy to produce the surface pattern 5 of the forming roller 3, and the type of pattern is not limited.

Further, the middle cylinder portion 3b may be formed as an air layer as in the embodiment shown in FIG. 3, and in this case, it is preferable to provide an inlet for outside air and an outflow hole for inside air.

Next, to explain the usage conditions of the present invention, for example, when applied to a highly viscous and still flexible coating material surface applied as a finish on a concrete foundation wall surface, under one-handed operation mode, The tool of the present invention, that is, the molding roller, is used as a pattern molding die to perform embossing by moving the pattern approximately flatly in vertical, horizontal, or diagonal directions while pressing appropriately.

In the present invention, the forming roller 3 is made of three layers, and in particular, the middle cylindrical portion 3b
Since a highly flexible material is used, even if there is some unevenness on the wall surface, etc., the inner cylinder part 3b and the outer cylinder part 3C will shrink and absorb the unevenness, as shown in Figure 4, ensuring reliable embossing. It has the effect of making it possible to do this, and it is efficient because it eliminates the detailed leveling process before embossing the finished wall surface, etc. It also eliminates the need for rework after embossing, which contributes to shortening the construction period. can.

Moreover, even if the pressing force on the forming roller 3 is uneven, the inner cylindrical portion 3b and the outer cylindrical portion 3. c.
Since the pressing force is absorbed by both sides, it is possible to create a beautiful embossing pattern even if the pressing force is slightly uneven, and the embossing process does not require as much skill as in the past. It will disappear.

In particular, the feature of the present invention is that after painting a wall surface, etc., it is smoothed out evenly before embossing, but some unevenness remains.

In order to accommodate this uneven surface, conventional single-layer elastic molded rollers were required to have a narrower roller width.

However, in the present invention, since the two layers are made of a soft material, it absorbs unevenness well and conforms well to the uneven surface, and the width of the roller can be made larger than that of the conventional one. Furthermore, when stamping with a forming roller, the border between the wall surface after stamping and the wall surface during the stamping process, with conventional forming rollers, a slight difference in pressing force causes a difference or an irregular pattern to appear. However, in the forming roller 3 of the present invention, the pressing force is absorbed by the outer cylindrical portion 3C and the middle cylindrical portion 3b, so that the above-mentioned drawbacks of the conventional molding roller 3 can be overcome.

Furthermore, as described above, if the outer cylindrical part 3C1 and the middle cylindrical part 3b are made of open cells and both parts are impregnated with a mold release agent, it is possible to apply the mold release agent to the molding roller one by one as in the conventional method. This method has great practical effects, such as eliminating the need for evaporation and dissipation of the mold release agent, and improving work efficiency.
