JPH09109123A - Decorating method for concrete block for building - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make it possible to alleviate the load to be applied to a decorating cutter by scraping the uneven surface of the waveform pattern formed at the time of molding a concrete block by the cutter mounted at the end of an intermediate parting board at the time of releasing from the mold. SOLUTION: The method for decorating a building concrete block comprises the steps of installing a molding Y by pushing down the molding Y and mounting it on a pallet P on a conveyor 23 directly thereunder to remove it, conveying it to a drying furnace of the later step, and curing it. In the case of releasing the molding Y from the mold, since a decorating cutter 15 is mounted at the lower end of an intermediate parting plate 14, the molding Y is released from the mold, pushed down. Thus, the face cell surface of the waveform pattern of the surface is scraped by the edge of the cutter 15, and the surface of the molding Y is scraped to the face cell surface of the surface pattern.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a makeup method for a concrete block for construction, which is used for an exterior decorative fence for outdoor use, an interior decorative partition for fences and the like.

[0002]

2. Description of the Related Art Conventionally, in the case of surface-processing the face cell surface of a concrete block for construction, after the molded product subjected to the vibration press processing is dried, it is subjected to polishing processing, spraying processing by shot blasting, or The surface of the concrete block is processed by dividing it into two parts.

[0003]

However, in any of the above cases, since the molded product is dried and then post-processed, it takes a lot of time and labor for post-processing, resulting in poor manufacturing efficiency. Therefore, the cost is high. In addition, transportation equipment and manufacturing equipment for post-processing are also required.

Therefore, Japanese Patent Application No. 7-
In the invention related to No. 244438, in order to improve the manufacturing efficiency, a forming mold is formed inside a vibrating mold of a concrete block, and the inside of the forming mold is partitioned by a partition plate, After filling the molding base of the concrete block inside the molding frame, in the method for manufacturing a concrete block for construction in which the vibration frame is driven to press the molding substrate, at the time of demolding the concrete block, A makeup method for a concrete block for construction is provided, in which a face cell surface of the concrete block is scraped off by a makeup blade attached to an end of a partition plate. As a result, when the molded concrete block is released from the mold, the face blade surface of the concrete block is scraped off by the decorative blade, so there is no need for post-processing, and the makeup on the face cell surface is removed from the molded product. It is possible to improve the production efficiency dramatically.

However, when the face cell surface of the concrete block is scraped by the above-mentioned method by the above-mentioned method, the bite force by the above-mentioned decorative blade may be lost to the load required for the scraping work. ,
It was confirmed that the quality of the molded product after demolding varied, for example, a part of the face cell surface was not evenly scraped.

[0006]

In order to solve the above-mentioned problems, therefore, in order to solve the above-mentioned problems, an uneven surface having a corrugated flat cross-section is formed on a partition plate of a molding frame, and when molding a concrete block. The present invention provides a makeup method for a concrete block for construction, in which a corrugated surface formed in a wavy pattern is scraped off by a makeup blade attached to an end of the partition plate when the concrete block is released from the mold.

That is, when processing the face cell surface of a concrete block with a decorative blade, from the viewpoint of reducing the load on the decorative blade, the face cell surface of the concrete block at the time of molding is once formed into a corrugated uneven surface. After that, it was possible to scrape with a makeup blade.

Then, the pallet P is pushed up from the lower part of the vibration form K by an elevating device (not shown), and as shown in FIG. 12, the vibration form K including the forming form S with the pallet P.
Close the bottom of the.

Next, from the rear side of the vibration press molding machine, as shown in FIG.
The horizontal finger F shown in FIG. 0 is extruded onto the pallet P, and this constitutes the lower mold part of the vibration form K as shown in FIG. Then, the material box (not shown) of the forming material X is pushed right above the vibration form K, and the forming material X of the material supply box is poured into the inside of the forming form S and filled. , Retract the supply box.

When the molding base S is filled with the molding base X as shown in FIG. 14, the upper mold U is pushed down from the upper part of the vibration press molding machine and descends to form the molding mold S. Core 15, half core 16, partition plate 11, core partition plate 1
The upper surface of the molding substrate X other than the portion 2 is pressed and pressed as shown in FIG. As a result, the molding base X is press-press molded while vibrating. At this time, a corrugated face cell surface 7A as shown in FIG. 17 is formed on the surface of the concrete block B to be formed.

When the press forming is completed after the structure shown in FIG. 17 is formed, first of all, the horizontal fingers F on the pallet P are set.
By moving backward, the horizontal fingers F are pulled out from the upper surface of the pallet P as shown in FIG. Finally, the pallet P on which the molded product Y is placed is started to be lowered by an elevating device (not shown), and at the same time, the upper mold U is pushed downward to push the molded product Y downward as shown in FIG. With the molded product Y placed on the pallet P, the molded product Y is placed on the transport conveyor 23 immediately below and taken out, and then transported to a drying furnace in a subsequent step for curing. When the molded product Y is released from the mold, since the makeup blade 15 is attached to the lower end of the intermediate partition plate 14, the makeup Y is released from the mold and pushed downward, Blade 15
17A scrapes off the wavy face cell surface 7A of the surface shown in FIG. 17, whereby the surface of the demolded molded product Y is the face cell surface of the surface pattern shown in FIGS. Scraped to 7.

[0018]

As described above, according to the present invention, the forming mold is formed inside the vibrating mold of the concrete block, and the inside of the forming mold is partitioned by the partition plate to form the molding mold. In a method of manufacturing a concrete block for construction, in which the inside of a mold is filled with a molding base of a concrete block, and then the vibration mold is driven to press the molding base, a flat plate is formed on the partition plate of the molding frame. The cross-section forms a corrugated surface with a corrugated pattern, and the corrugated surface formed during molding of the concrete block is scraped off by a makeup blade attached to the end of the partition plate when the concrete block is demolded. We have provided a makeup method for architectural concrete blocks, which is characterized by being processed. When removing from the mold, it can be scraped off with a decorative blade attached to the partition plate, eliminating the trouble of post-processing after drying the molded product as in the past, and dramatically improving manufacturing efficiency. In addition, it contributes to the reduction of manufacturing cost. In particular, in the case of the present invention, the face cell surface of the concrete block at the time of press molding is once formed into a corrugated uneven surface and then scraped by a makeup blade, so that the concrete blade is used to make concrete. When processing the face cell surface of the block, the load applied to the decorative blade can be significantly reduced. Therefore, even when the face cell surface of the concrete block is scraped off with the decorative blade as in the case of the prior art of Japanese Patent Application No. 7-244438, the load required by the scraping is cut by the decorative blade. The force is not lost, and as a result, various effects such as uniform quality of the molded product after demolding are brought about.
