Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing mortar or concrete secondary products such as retaining wall blocks with an uneven pattern on the front surface of the product.

Conventionally, when manufacturing patterned retaining wall blocks, mortar for the facade was filled into the space formed by the frame edge plate of the slope pallet and the pattern-forming rubber mat at the bottom of the face/arm let, and the face pallet was then moved up and down. Invert the formwork body and insert it into the upper opening 1-], turn the formwork body upside down and apply appropriate vibration or compression to unite the concrete in the formwork body and the mortar in the face/gret. After joining and removing the product from the mold and hardening, the surface pallet is removed from the front of the product to create an uneven pattern on the front of the product.

However, in the conventional manufacturing method, only one type of decorative mortar is filled in the space of the face/2 let, and the color of the mortar in the recesses of the pattern forming mat and the mortar on the upper surface of the mat other than the recesses are different from each other. Since the colors of the layers are exactly the same, the appearance of the front of the product depicted by removing the mat will be monotonous unless the uneven pattern is formed deep enough to create a shadow contrast caused by light rays, and when viewed from a distance, it will look a little different. The uneven pattern is well recognized, and the front part of the product only gives the impression of a flat plate.

Therefore, an object of the present invention is to provide a method for manufacturing a patterned mortar or concrete secondary product, which adds a color contrast to the uneven pattern on the front of the product, thereby making it possible to more clearly depict the uneven pattern. It is to be.

Hereinafter, the gist of the manufacturing method of the present invention will be explained based on the drawings.
The mat 1 is filled with mortar 4 of a different color from the mortar layer 3 formed on the upper surface of the mat, and the mat 1 is used to mold at least the front part of the product.

The illustrated embodiment shows an example in which the method of the present invention is applied to the manufacture of a retaining wall Glock in which the subject part is molded with concrete, and the pattern drawing recess 2 is directed upward as shown in Fig. 3 (a). As shown in FIG. 1, the rubber mat 1 is sequentially conveyed by a belt conveyor 6. A mortar spreading pressure roll 7 is installed above the middle part of the belt conveyor 6, and the rubber mat 1 is conveyed in the mat conveying direction. The roll 7 rotating in the opposite direction moves the mortar 4 placed on the top surface of the mat as shown in Fig. 3 (b).
The mortar 4 is spread over the entire surface of the mat 1 as shown in FIG.
into the recess 2 of the mat. Scraping plates 8 and 9 made of two pieces of hard rubber are installed above the terminal end of the belt conveyor 6, and their lower ends are matted in a somewhat curved state as shown in FIG. 3(c). 1 is in sliding contact with the top surface. When the mat 1 passes under the scraping plates 8 and 9, the recess 2
The excess mortar 4 on the upper surface of the mat 1 is prevented from passing by the lower ends of the scraping plates 8 and 9, as shown in FIG. The excess mortar 4 scraped off from the upper surface of the mat in this way moves along the scraping plate 8.9, which is arranged a little further than the mat conveying direction, as shown in FIG. It is removed to the side of the conveyor 6. As shown in FIG. 3(E), the mat 1 containing the mortar 4 only in the recess 2 is transferred to the adjacent roller conveyor 10, and is placed on the inspection stand 11 fixed at the end of the conveyor, if necessary. Repairing the filling of the mortar 4, that is, manually filling the leakage location with the mortar 4 is performed. The imitation mat 1 is fitted into the surface pallet 12 with the concave portion 2 facing upward, as shown in FIG. A mortar 3 having a different color from the mortar 4 is filled into the space. Thereafter, according to a conventional method, the surface pallet 12 is turned upside down and inserted into the upper opening of the form body 14, and then, as shown in Fig. 4, the form body 14 is turned upside down together with the surface pallet 12, The concrete 5 in the formwork body and the mortar 3 in the surface pallet 12 are separated by appropriate vibration and pressure.
are integrally joined. The surface pallet 12 is used as a mounting plate for the product even after the product is demolded, and is removed from the product when the product is sufficiently cured.

At the same time as the surface/9 let 12 or after removing the surface pallet,
By removing the mat 1 from the front of the product, the -kiri manufacturing process is completed. In addition, the mat 1 and the surface pallet 12 are temporarily fixed by providing a suction cup structure on the bottom surface of the mat and vacuum-adsorbing the bottom surface of the mat to the inner bottom surface of the surface 9 red. The mat is magnetically attracted to a metal surface pallet, and the mat is adsorbed using a release agent applied to the inner bottom of the surface pallet. The uneven patterns formed on the mat include wood grain patterns, floral patterns, mosaic patterns, geometric patterns, etc.
Various shapes and patterns can be used.

The method of the present invention can be used not only for the above-mentioned retaining wall blocks, but also for producing two-break mortar products and two-break concrete products for use in civil engineering or construction, such as magnet Glock, paving stone Glock, interior and exterior wall covering materials, and building blocks. Since it is a material, there are no particular restrictions on the thickness, shape, or size of the product. Furthermore, there are no particular restrictions on the material or attributes of the mat, and the mat may be attached directly to the formwork body without using a surface pallet, or the mat may be configured as a part of the formwork body. can.

Further, when there are a plurality of recesses, the color of the mortar filled in the recesses can be made different for each recess.

As described above, in the manufacturing method of the present invention, mortar 4 is filled in the four parts 2 provided on the upper surface of the pattern forming mat 1, and a mortar layer 3 having a different color from this mortar 4 is formed on the upper surface of the mat. Because at least the front part of the product is formed using mat l, it is different from conventional patterned mortar or concrete two-break products that rely solely on the uneven shape.
The uneven pattern on the front of the product is contrasted with color, which makes the uneven pattern stand out clearly.

In addition, when drawing a colored pattern of two colors or three or more colors, two or three or more types of colored particles or layered colored mortar with different specific gravities are sprinkled on the top surface of the mat at the same time or with the one with the highest specific gravity first. Then, by leveling it with a brush and filling the four parts of the upper surface, vibration is applied to the mat, particles, and mortar to cause particles and mortar with a large specific gravity to sink and move to the deep part of the recess, while reducing the specific gravity. When small particles and mortar are floated to the shallow part of the recess or outside the recess, there are parts where only or the majority of particles and mortar have a large specific gravity, and parts where only or the majority of particles and mortar have a small specific gravity. It is possible to form a part where particles or mortar with a large specific gravity and particles or mortar with a small specific gravity are mixed, thereby making it possible to easily create color shading and shading.
