Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative method of a concrete block for building used for an exterior decorative fence outdoors, an indoor interior partition decorative fence, and the like. 2. Description of the Related Art Conventionally, when a face cell surface of a concrete block for architectural use is subjected to surface treatment, a molded product subjected to vibration press processing is dried, then polished or sprayed by shot blasting. Or the surface is processed by dividing the concrete block into two. [0003] However, in each of the above cases, the molded product is subjected to post-processing after being dried, so that it takes time and effort to perform post-processing, and the Due to lack of efficiency, costs are high. In addition, transport equipment and manufacturing equipment for post-processing are required. [0004] In view of this, Japanese Patent Application No. Hei.
In the invention according to No. 244438, in order to improve the production efficiency, a forming form is formed inside the vibrating form of the concrete block, and the inside of the forming form is partitioned by a partition plate. After filling the molding base of the concrete block into the molding form, in the method of manufacturing a concrete block for building to press and press the molding base by driving the vibration mold, at the time of demolding the concrete block, There is provided a decorative method of a concrete block for building, wherein a face cell surface of the concrete block is scraped by a decorative blade attached to an end of a partition plate. As a result, when the molded concrete block is removed from the mold, the face of the face cell of the concrete block is scraped off by the decorative blade, so that post-processing is unnecessary, and the makeup on the face cell surface is removed from the molded product. The manufacturing efficiency can be drastically improved. However, when the decorative surface of the concrete block is formed into, for example, an uneven surface having a corrugated pattern when viewed from the top, and the decorative surface is roughened, the decorative surface can be improved. According to the processing method of the earlier application,
It has been found that the following problems occur. That is, immediately after the mold release, when the face cell surface of the uncured concrete block is scraped by a decorative blade so as to dig in a wavy pattern, the load required for this processing loses the biting force of the decorative blade. There is dislike, and as a result, a part where the scraping is not performed uniformly is formed on a part of the face cell surface, and the quality of the molded product varies. [0006] In order to solve the above-mentioned problems of the invention of the prior application, a method of making a concrete block for a building according to the present invention is described below. In the manufacturing method of providing a forming mold having a middle partition plate for forming, filling the forming base into this form, and pressing the forming base while vibrating the mold, the forming surface of the middle partition plate A top surface shape forms an uneven surface forming a wave pattern, and a lower end or an upper end of a partition plate is provided with a shape corresponding to the uneven surface, and a decorative blade slightly protruding from the uneven surface is attached. When the molded article is removed from the mold, the corrugated surface formed on the surface of the molded article is scraped by the decorative blade to be roughened. As described above, according to the present invention, by forming the molding surface of the partition plate in advance on the corrugated uneven surface, the role of the decorative blade is formed when the concrete block is released from the mold. It is only necessary to scratch the corrugated uneven surface and roughen this surface. Therefore, as in the prior application of Japanese Patent Application No. 7-244438, when the concrete block is released from the mold, the flat molding surface formed by the partitioning plate is scratched so as to "go around", and the corrugations are formed all at once. Unlike a decorative blade, which has a role of shaving a patterned uneven surface, the load applied to the decorative blade can be significantly reduced.
