Description

[Detailed Description of the Invention] This invention relates to a pattern creation method tool for architectural coating materials, etc., and more specifically, it is used for finishing purposes on internal and external walls, ceilings, floors, etc. of buildings, stores, etc. The present invention relates to a tool for creating an uneven three-dimensional decorative pattern on the surface of a coating material.

In recent years, with the remarkable development of the construction industry, there is a strong demand for decorative patterns that are not only based on color, but also have excellent three-dimensional aesthetic beauty, such as textured surfaces, especially in the field of single finishing for walls, etc. It is being done.

In order to meet this demand, conventionally, for example, a roller member was used to form a desired patterned surface on the outer periphery of the surface of the coating material, which was painted to the required thickness by spraying, troweling, etc. on the concrete foundation wall surface. The mold was leveled and moved in directions such as up and down, left and right, while being pressed directly to create a three-dimensional pattern.

However, since the coating material used for many minutes is highly adhesive so that it strongly adheres to the foundation wall side, this has the disadvantage that it does not adhere strongly (adhesion resistant) to the outer periphery of the roller member. As a result, during mold leveling or when separating the roller member from the coating material, some of the coating material that has bitten into the surface of the roller member, especially the molding surface, and is resistant to adhesion, is removed from the coating material while remaining adhered to the roller member. As a result of this separation, the uneven patterned parts of the embossed coating material, especially the curved parts, lose their shape, making it impossible to create elaborate or even complex patterns, and requiring several repairs after leveling the mold. This required a lot of work, which lengthened the construction period and caused problems such as high construction costs.

The present invention was devised as a result of long-term research and ingenuity in view of the above-mentioned problems, and focuses on the relationship between the mold releasability between the coating material and the molded part, and improves the mold releasability between the two. A tool designed to create patterns is provided to quickly and efficiently create decorative patterns with excellent three-dimensional design beauty.

Note that the above-mentioned coating material according to the present invention is water-soluble,
Single or composite materials such as inorganic Portland cement, silica cement, alumina cement, blast furnace cement, water slag, mine slag, gypsum, silica sol, plasters, vinyl acetate resin emulsion, acrylic resin emulsion, epoxy resin emulsion, synthetic comb latex, etc. It is assumed that it was used in

Embodiments of the present invention will be described below with reference to the drawings.

The tool of this example is of a roller type as shown schematically in Figs. A forming roller 3 is rotatably supported via a support shaft 4 that is removably inserted and suspended between the ends of short receiving rods 1b and Ib at both ends of the support rod 1a. A net-like covering material 5 (also simply referred to as a net) is formed around the outer periphery of the covering material.

) is covered. This forming roller 3 is constructed by fitting and press-bonding a rubber outer cylinder 3b having appropriate elasticity and corrosion resistance onto a metal inner cylinder 3a. A large number of grooves 6.6 are formed over the wall surface to form a desired pattern, thereby creating an uneven surface.

On the other hand, the net 5 is used to prevent the coating material M from adhering to the forming roller 3, and is made of a synthetic fiber having appropriate elasticity and elasticity, corrosion resistance, etc., and is woven into an endless shape with a relatively small mesh. A rubber band 7.7 or the like is inserted into the openings at both ends.

To attach the net 5 to the forming roller 3, expand the opening with one rubber band 7, insert it from one side of the forming roller 3, and insert both ends of the net 5 into each end surface of the forming roller 3. The molding roller 3 is placed in a state where the molding roller 3 is properly stretched and is closely covered with the outer periphery of the forming roller 3, and can be removed.

An example of creating a desired uneven pattern using the tool configured as described above will be described.

In other words, for example, a concrete base wall C in a building or a store, etc., is coated with a left-hand trowel for finishing purposes, and the adhesiveness is high. Below, as illustrated in FIG. 4, the forming roller 3 is moved vertically, horizontally, or diagonally in a plane while being appropriately pressed so as to slightly inject the pattern forming mold.

In this so-called roller leveling operation, first, when the forming roller 3 is pressed against the coating material drawing, as illustrated in the figure, the pressing force of the forming roller 3 against the coating material M is Part of the coating material M, while being blocked by the net 5, bites into the concave groove 6.6 on the outer periphery of the forming roller 3 and is molded into an uneven shape. As the coating material M is molded, the net 5 interposed between the molding rollers 3 is pressed more closely against the outer periphery of the forming roller 3, and is pushed into the grooves 6, 6 while being stretched as appropriate with its elasticity and elasticity. Rushing in and forming the entire roller 3
It deforms into irregularities along the outer periphery while remaining in close contact with each other.

During the plane movement of the forming roller 3, the net 5 maintains the boundary line between the two in the above-mentioned state by 3°M.

Then, when the forming roller 3 is separated from the coating material M upon completion of the above-mentioned roller type leveling operation for the required area of the coating material M, the net 5 is removed from the forming roller 3 as shown in C at the same time. At the same time as the pressing force is released, the entire roller coating (including the portion of the forming roller 3 which has been deformed by thrusting into the groove 6) instantly returns to its original stretched state with its elasticity and elasticity.

Due to this expansion/contraction return action, the entire surface of the coating material M, especially the convex portions M1 formed by protruding into the grooves 6 of the forming roller 3,
Even if they are in contact with the net 5, they are all appropriately pushed back toward the coating material M side (the side opposite to the forming roller 3).

As a result, both parties 3. The so-called mold release property between M is improved, the adhesion resistance phenomenon during mold release is eliminated, and the surface of the coating material M has a three-dimensional pattern D (e.g. Flowers, geometric patterns, etc.) can be created quickly, efficiently, and in an expansive manner.

Note that after the above-mentioned pattern creation work is completed, the same pattern creation work is repeated on the next surface of the coating material M.
(The forming roller 3 may be replaced with a different type.

) At this time, if the forming roller 3 is overlapped and leveled in a certain width range part with respect to the pattern part that has already been created,
Patterns with different aesthetic designs can be created in the portions, and at least two or more different designs can be alternately developed on the entire surface of the coating material M.

Of course, in the above-described pattern forming operation method, the forming roller 3 may be leveled at predetermined intervals.

However, in either case, since the mesh of the net 5 is relatively small, no leveling traces of the net 5 remain on the patterned surface.

After the pattern creation work is completed, the net 5 and the forming roller 3 may be simply washed with water.

At this time, the support frame 1, support shaft 4, roller 3, and net 5 can be stored while being disassembled.

Regarding the above-mentioned mold releasability, when the roller 3 rotates, one side expands and comes into close contact with the outer periphery of the roller 3, while the other side expands, making use of the fact that the covering material 5 has a net structure, elasticity and stretchability, and non-water absorbency. is appropriately loosened to allow an air curtain layer to exist between the roller 3 and the coating material M, and the effect of not absorbing moisture in the coating material M improves the releasability of the roller 3 and the coating material M. It can be considered that it can be further improved.

A part of the illustrated tool may be changed as appropriate.

For example, the forming roller 3 may be formed by integrally molding the inner and outer parts of a metal material in addition to a rubber material or a synthetic resin material, and the forming surface shape may include protrusions, grooves, etc. in the circumferential direction and the axial direction as appropriate. The material, shape, etc. may be arbitrarily selected.

Note that it is free to change the shape of the support frame 1 and to use a plurality of forming rollers 3.

On the other hand, the mesh of the covering material (net) 5 for preventing coating material adhesion can be appropriately thickened (if this is done, a mesh pattern can be expected to appear in addition to the uneven pattern created by the forming roller 3).

Of course, this covering material 5 may be made of rubber or the like in addition to synthetic resin fiber having appropriate elasticity and elasticity.

In addition, regarding the operation mode of the tool itself, including changing the support frame 1, we changed from a hand-held type to a large mechanical automatic type, and the forming roller was moved up and down and left and right.

It may be configured such that the tilting movement and the pressing force (biting amount) against the coating material M can be adjusted.

The present invention can be applied to, for example, walls and ceilings inside and outside buildings and stores, etc.
As a pattern creation tool for designing three-dimensional design patterns on floors, etc., a suitable number of roller-shaped molding tools are used to level out the shape while pressing the support frame member against the surface of the architectural coating material. The member is attached detachably and replaceably, and a predetermined pattern molding surface with a concavo-convex shape that allows for a continuous pattern, such as protrusions, grooves, protrusions, depressions, etc., is formed on the surface of this molded member, and an appropriate pattern is formed on the molded surface. Since this tool is removably covered with a non-water-absorbing net-like covering material that has elasticity and stretchability, it can be easily and easily handled by itself, for example, as a [pattern-creating plastering tool with covering material]. It is easy to operate and can be easily brought into the field.

By simply pressing this tool against the coating material and leveling it in a rotational manner, it is possible to efficiently create a three-dimensional continuous decorative pattern with unevenness on the surface of the coating material.

In particular, in the tool of the present invention, an air curtain layer exists between the coating material side and the molded part side using a net-like coating material to improve mutual mold releasability, so that the coating material is sticky. It is a sophisticated and stable product with excellent three-dimensional design beauty that does not lose its shape and adapts to the molding surface of arbitrarily selected molded parts, with easy operation even when the surface is flat, curved, or has a complex pattern. Decorative patterns can be freely created, and even an unskilled person can quickly create them.

Furthermore, in the tool of the present invention, an appropriate number of the above-mentioned molded members can be attached to the supporting frame member, for example, in a single type with one molded member, or in a composite type with two or more molded members, etc. In particular, if the molded members are arranged in parallel with each other, If composite patterns are arranged in series, a plurality of different types of patterns can be successively created at the same time.

In either of the above-mentioned single or composite formats, by attaching the molding member to the support frame member in a detachable and replaceable manner, it is possible to create not only a fixed pattern but also different kinds of continuous patterns.

By replacing the above-mentioned net-like covering material with a new one as the molded member is replaced, the molding can be carried out while always maintaining appropriate mold releasability.
