JPH09157070A - Formation of pattern on surface of concrete plate - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a method for forming surface patterns which cuts out part of the surface to be decorated of a concrete plate and forms the patterns of characters, designs, etc., of different materials in the cut out parts. SOLUTION: The surface to be decorated of the concrete plate 1 is partly cut out with the patterns of the characters, designs, etc., by a jet cutter using high-pressure fluid. Insert pattern pieces 6 formed of concrete or other materials to the same shape as the shape of the cut out parts and to the same thickness or different thicknesses are fitted into the cut out parts to form the characters, designs, etc., again, by which the distinct patterns are formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a surface pattern by cutting out a part of a decorative surface of a concrete board and forming a pattern such as a character or a pattern, which is a different material, in the cut out portion. Is.

[0002]

2. Description of the Related Art Conventionally, as a method of forming a pattern on the surface of a concrete board, mortar,
Spray synthetic resin paints, ceramics, etc., paste tiles, bricks, stones, etc., or apply a retarder to the form, or attach paper or cloth impregnated with the retarder to the form, There is a method of pouring concrete, and then washing out the portion where the hardening is delayed by a retarder after pouring, that is, a pouring method.

[0003]

The above-mentioned spraying of mortar, synthetic resin paint, etc., or sticking of tiles, stones, etc., is a makeup that lacks a three-dimensional effect and is expensive depending on the spraying or sticking material. It was uneconomical. In addition, in the case of using a retarder, it is necessary to control the date and time of production of the concrete board.If this is mistaken, the portion where the retarder is used cures too much and the part is washed out cleanly. When it is not possible and the formed characters, patterns, etc. have complicated patterns, the outline is unclear, and clear characters, patterns, etc. cannot be obtained. In addition, the engraving depth of the letters and patterns of this wash-out method is normally only a few millimeters, and there are drawbacks such as deep engraving and a pattern rich in three-dimensionality, which has the effect of creating a landscape. It was something that could not be fully demonstrated.

[0004]

Therefore, the present invention has been proposed in order to solve the above-mentioned drawbacks, and its constitution is as follows.
A part of the decorative surface of the concrete board is cut out in a pattern by a jet cutter with a high-pressure water flow, and the cutout part is made of concrete or other material and has the same shape and thickness as the cutout part. Or a set of inlaid pattern pieces having different thicknesses are fitted to re-form characters, patterns, etc., and desired patterns of characters, patterns, etc. are created.

[0005]

The method according to the invention will now be described with reference to the drawings. 1 to 5 show the order of the forming method of the present invention. Reference numeral 1 is a concrete board, and 2 is a cutout portion formed by cutting out characters, patterns, etc. formed in a part of the decorative surface of the concrete board. In the case of the embodiment, the letter H is shown. 3 is a jet cutter by a high-pressure jetting device used for cutting, 4 is its nozzle, 5 is a high-pressure water stream jetted from the nozzle 4, and the water stream cuts out the concrete board 1. is there. The discharge pressure and water amount of the jet cutter 3 can be freely changed. Further, by mixing the abrasive powder with the high-pressure water stream 5, it is possible to effectively and quickly cut out. Reference numeral 6 is a fitting pattern piece that fits into the cutout portion 2 on the surface of the concrete plate 1, is made of concrete or another material, has the same shape as the cutout portion 2, and the same thickness as the cutout portion 2, Or it is formed in different thickness, and this is cut out,
They are simply fitted tightly or if necessary via an adhesive. The present invention may be carried out in a factory, or in order to carry out on-site construction concrete plates, a jet cutter 3 by a high-pressure injection device is mounted on a truck and transported to a construction site, where formation processing is performed. You can go.

[0006]

According to the present invention, the concrete board 1 is cut out by the jet cutter 3 in an appropriate pattern and the cutout portion 2 is formed, so that the work can be performed quickly, accurately and easily. Since a fitting pattern piece 6 made of concrete or another material is fitted into the cutout portion 2, a pattern such as letters or a pattern can be clearly shown on the concrete plate 1. Further, since the fitting pattern piece 6 is fitted into the cutout portion 2, there is no need for time management such as the washing-out method with a retardant in the conventional pattern forming method, and without complicated work, The effect is that it is possible to form a concrete boundary between the concrete 1 and the pattern.
