DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for making a concrete block for architectural use, which is used for an exterior decorative fence outdoors or an indoor interior partition decorative fence.

[0002]

2. Description of the Related Art Conventionally, when a face cell surface of an architectural concrete block is subjected to surface processing, a molded product subjected to vibration press processing is dried, then polished, 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 article is dried and then post-processed, so that it takes time and effort for post-processing and lacks production efficiency. Therefore, the cost is high. In addition, transport equipment and manufacturing equipment for post-processing are required.

[0004]

Therefore, in order to solve the above-mentioned problems, according to the present invention, a forming form is formed inside a vibrating form of a concrete block, and the inside of the forming form is formed. After forming a partition by a partition plate, filling the molding base of the concrete block into the molding form, the method for manufacturing a building concrete block for pressing and pressing the molding base by driving the vibration mold. Provided is a method for making a concrete block for building, wherein a face cell surface of the concrete block is scraped off by a decorative blade attached to an end of a partition plate when the concrete block is released.

[0005] In short, by attaching a decorative blade to the end of the intermediate partition plate of the molding frame, when the molded product is removed from the mold, the decorative blade scrapes the face cell surface of the concrete block. Therefore, it is characterized in that the makeup on the face cell surface is performed together with the removal of the molded article without the need for post-processing.

Supported.

Therefore, based on the above-mentioned constituent members,
An outline of a manufacturing process for manufacturing four molded products of the concrete block B at a time will be described with reference to FIGS. First, a molding mold S is placed inside a vibration mold K, as shown in FIG.
After setting as shown in FIG. 11 and operating the drive motor (not shown) of the vibration press molding machine,
When molding is started in a state where vibration is applied, first, the pallet P is pushed up from below the vibrating mold K by a lifting / lowering device (not shown), and as shown in FIG. Vibrating formwork K including forming formwork S at P
Close the bottom of.

Next, from the rear side of the vibration press molding machine, FIG.
The horizontal fingers F shown in FIG. 0 are pushed out onto the pallet P, thereby forming the lower mold portion of the vibration mold K as shown in FIG. Then, a material box (not shown) of the forming base X is extruded immediately above the vibration form K, and the forming base X of the supply box is poured into 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 vibrating press molding machine and descends. 15, half core 16, partition plate 11, middle partition plate 1
The upper surface of the molding base X other than the part 2 is pressed and pressed as shown in FIG. As a result, the green compact X is pressed and formed while vibrating.

When the press forming is completed, first, the horizontal fingers F on the pallet P are moved backward to move 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 loaded is started to be lowered by an elevating device (not shown), and at the same time, the upper die U is pushed down, thereby pushing the molded product Y downward as shown in FIG. With the molded product Y placed on the pallet P, the transport conveyor 23 immediately below
After being set on the top and taken out, it is conveyed to a curing / drying oven in the subsequent process. When removing the molded product Y, the partition plate 1

As shown in FIG. Then, when the decorative block 25 is attached to the lower end portion of the intermediate partition plate 24 and the concrete block B is formed in the same manufacturing process as above, the face cell surface 27 of the surface convex portion 26 of the block main body 1 has , Is scraped by the decorative blade 25, and finally, as shown in FIG.
A concrete block B is obtained.

[0016]

According to the present invention, as described above, a forming mold is formed inside a vibrating form of a 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 inside of the mold, 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 of the concrete block,
Since the face cell surface of the concrete block is provided with a decorative method for a building concrete block by scraping the face cell surface with a decorative blade attached to the end of the partition plate, the processing of the face cell surface of the concrete block is performed by a molding die. When the molded product is released from the frame, it can be scraped off with a decorative blade attached to the partition plate.This eliminates the inconvenience of post-processing the molded product after curing and drying. Is dramatically improved, and various effects are brought about, such as contributing to reduction of manufacturing cost.
