Description

Description: TECHNICAL FIELD The present invention relates to a method for producing a concrete decorative wall material used for a retaining wall, a bridge pier, and the like, and more specifically, a civil engineering having a mosaic pattern formed on an outer surface. The present invention relates to a method of manufacturing a decorative wall material made of concrete for use.

(Prior Art) Conventionally, a concrete wall material used for a retaining wall usually has a flat outer surface and is not provided with a pattern or the like.

However, in recent years, it has been required to install retaining walls that match the natural environment and also show aesthetic appearance.
BACKGROUND ART Concrete wall materials for civil engineering in which various surface treatments are performed on the surface of the wall material are being proposed.

Hereinafter, an example of a well-known surface-treated concrete wall material for civil engineering will be described with reference to the drawings.

Referring to FIG. 4, the wall material is composed of a wall substrate 1 and a decorative panel plate 2 such as a tile, and the entire surface of the wall substrate 1 is adjacent to the decorative panel plate 2. Buried. A joint 3 is applied to the gap between the adjacent decorative panel boards 2.
Has been made.

The wall material is manufactured by precasting using a mold as shown in FIG.

Referring to FIG. 5, the formwork comprises a bottom formwork 4 made of iron or wood, a side formwork 5, and an upper formwork 6, and a decorative panel plate 2 is fitted and installed on the inner surface of the bottom formwork 4. Recesses 7 are formed adjacent to each other.

The wall material with the decorative panel plate is manufactured as follows.

In manufacturing, first, the concave portion 7 is formed in the bottom mold 4,
The decorative panel plate 2 such as a tile is fitted into the concave portion 7 of the bottom formwork 4 and disposed. Then, ready-mixed concrete is put in, the upper mold frame 6 is covered, and the put-in concrete is solidified. In the wall material thus obtained, the adjacent decorative panel plate 2
Since there is a gap therebetween, the gap between the adjacent decorative panel boards 2 is jointed 3 to obtain the wall material shown in FIG.

In addition, a colored decorative panel board may be used as the decorative panel board 2, and a pattern or the like may be drawn on the decorative panel board.

On the other hand, as a construction wall panel, a construction shown in FIG. 6 is also known.

That is, the base material 11 of the wall panel is manufactured by precasting, and then the surface of the base material 11 is grooved in a mosaic pattern.
Then, the decorative member 12 is attached to the groove with a mortar or other glue to form a decorative wall panel.

(Problems to be Solved by the Invention) Since wall materials for civil engineering are used in large quantities, they must be precast at low cost and easily manufactured. However, the wall material for civil engineering having the structure shown in FIG. 4 has a large number of expensive decorative panel boards 2 attached thereto, so that the material cost is high and the wall material for civil engineering is required to have low cost. Was not preferred.

Furthermore, in the manufacturing method as shown in FIG. 5, a large number of decorative panel boards 2 must be installed on the bottom form 4,
The work is troublesome. In addition, after precasting, since the work of bonding the joints 3 between the adjacent decorative panel boards 2 is also troublesome, a long time work is required and the cost is unavoidable.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for manufacturing civil engineering wall materials having a decorative surface with good workability and low cost.

(Means for Solving the Problems) A feature of the present invention is a method of manufacturing a concrete wall material for civil engineering by putting ready-mixed concrete into a mold, comprising a plate-like body having a predetermined thickness, A patterning mat having a cutout arranged in a pattern is disposed on a bottom mold, and a decorative member is disposed in the cutout of the patterning mat. A method for producing a decorative wall material made of concrete for civil engineering, characterized in that ready-mixed concrete is put on a mat, covered with an upper formwork and solidified, and further arranged in a pattern on the patterned mat. In addition to the provided holes, grooves or projections formed in a pattern are provided.

Example An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows a wall material 21 for civil engineering according to one embodiment of the present invention, and a decorative member 22 is provided on the surface of the wall material 21 so as to protrude in a mosaic pattern. In addition, a wavy pattern 23 and a linear pattern 24 are formed in a projecting shape or a groove shape in a portion where the decorative member 22 is not provided.

The wall material 21 according to the present invention is used as a retaining wall on both sides of a road or a railway line formed by cutting, or as a wall material for a large pier, and the pattern attached to the wall material 21 is natural. Designed to match the environment.

FIGS. 2 and 3 show an example of a method of manufacturing the wall material 21 having the above configuration.
This will be described with reference to the drawings.

The mold includes a bottom mold 25, a side mold 26, and an upper mold 27. Each of the molds 25, 26, 27 has a flat inner surface. A patterning mat 28 is provided on the bottom formwork 25.
As shown in FIG. 3, the patterning mat 28 is made of a plate-like body having a predetermined thickness, and has a hole 29, a groove or a projection 30 formed in a pattern.

In manufacturing, first, the patterning mat 28 is attached to the bottom form 25
On top of Then, the decorative member 22 forming a mosaic pattern or the like is arranged in the hole 29. Next, ready-mixed concrete is charged and the upper mold frame 27 is covered. Then, when the poured ready-mixed concrete is solidified and taken out, a wall material 21 having a mosaic pattern, a straight line, and a wavy pattern on the surface is completed.
In this case, the protrusion amount of the decorative member 22 is determined by the thickness of the patterning mat 28.

If a plurality of patterning mats 28 are prepared, various patterning wall materials 21 can be obtained with the same mold.

In the above description, the linear pattern and the waveform pattern are not always necessary and can be omitted.

Instead of a linear pattern or a wavy pattern, another geometric pattern such as an arc pattern or a spiral pattern can be applied.

Further, as a material of the patterning mat, an appropriate material such as rubber or wood can be selected in addition to metal such as iron.

Furthermore, when a wooden member or a rock member is used as the decorative member, for example, the pattern is more matched to the natural environment.

Further, the surface of the wall material 21 is finely surface-treated by sand blasting or the like, so that the wall material 21 can be further matched to a natural environment.

(Effects of the Invention) The effects of the present invention configured as described above are as follows.

Since it is only necessary to use a patterning mat and form a pattern-shaped hole, groove or projection in the patterning mat, the groove material or the like is applied to the wall material of the precast product like a conventional building wall panel. The work for forming the pattern is quicker and easier than the work of attaching and decorating the decorative member.

Since the decorative member is not attached to the entire surface of the wall material, there is no possibility that the cost will increase even if an expensive decorative member is used.

By using the same formwork and preparing multiple types of patterning mats, it is possible to obtain as many decorative wall materials as the number of types. Can be
