Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to concrete, mortar, etc. such as side walls of underpasses where roads intersect three-dimensionally, side walls inside and outside buildings, boundary walls, exhibition walls for events, etc. The present invention relates to a method for forming a three-dimensional pattern composed of uneven patterns and patterns (collectively referred to as patterns in this document) on the surface of a large-sized wall body formed by casting a curable fluid material such as gypsum.

<Prior Art> As described above, a pattern expression member is formed on the inner surface of the front formwork plate located on the front surface side of the wall body among the formwork plates for forming the wall body by casting the curable fluid material. A method for forming a three-dimensional pattern on the surface of a wall body which is fixed and expresses a concave or convex three-dimensional pattern corresponding to the above-described pattern expressing member on the wall surface is known from Japanese Patent Publication No. 62-9439.

The pattern expression member of the above-mentioned conventional example is composed of a substrate and a cutout plate cut out from the substrate, and the cutout plate is engraved to form an uneven pattern. It is configured by inserting and fixing in a cutout hole in the substrate.

Therefore, by fixing it to the inner surface of the front formwork plate,
A recess having an uneven pattern can be formed on the surface of a wall body constructed with a patterned cutout plate inserted and fixed in the cutout hole (Fig. 8), and a through hole of the same shape and size as the substrate is formed on the front formwork plate. Is provided, and the substrate is fixed to the through hole from the outside to close the through hole, so that the uneven pattern by the cutout plate with the pattern inserted and fixed to the substrate can be projected from the surface of the wall body. (Fig. 9).

<Problems to be Solved by the Invention> In the above-mentioned conventional example, since the surface of the wall body is decorated with the surface of the substrate and the concavo-convex pattern of the patterned cutout plate inserted and fixed in the cutout hole of the substrate, the three-dimensional effect is poor.

In addition, it is possible to express a splattering decoration on the surface of the wall body by fixing a plurality of substrates on which the patterned cut-out plates are fitted and fixed so as to be separated from each other on the inner surface of the front formwork plate. However, a large continuous pattern cannot be expressed by the plurality of substrates.

Furthermore, the method of mounting the substrate on the front form plate differs between the case where a recess having an uneven pattern is formed on the surface of the wall and the case where the uneven pattern is projected from the surface of the wall. Requires.

<Means for Solving the Problems> Therefore, the present invention is rich in three-dimensional effect and can also express a large continuous pattern in which a plurality of substrates of the above-mentioned conventional example are adjacent to each other.
In addition, the pattern can be formed on the surface of the wall body in the same manner as concave or convex, and the surface located on the surface side of the wall body to be constructed can be formed before the setting of the curable fluid material. A plurality of partition plates of the same shape and size are laid and fixed in the pattern formation area on the inner surface of the form plate, and the pattern expression member is formed on the pattern board of the same shape and size as the partition plate so that the pattern expression member can be separated. It is characterized in that the lever-shaped pattern substrate is stacked on each partition plate together with the pattern expression member, the pattern expression member of each pattern substrate is fixed to the partition plate, and the residue of the pattern substrate is removed from the partition plate. And

<Embodiment> In each of the illustrated embodiments, 1 and 2 are large formwork plates for constructing the wall body 3 by casting a curable fluid material C such as ready-mixed concrete, and made of, for example, veneer plywood, Surface 3'of wall 3
The formwork plate 2 located on the side is the front formwork plate.

In the pattern forming region on the inner surface of the front formwork plate 2, a partition plate 4 having a required thickness and made of a foamed resin such as Styrofoam having a size of 90 cm × 180 cm is horizontally long and vertically divided into four. Steps, three rows in the lateral direction, a total of 12 sheets, are laid out in an adjacent pattern, and fixed by gluing or nailing.

Reference numeral 5 is a pattern substrate of the same shape and size as the partition plate 4 and made of the same foamed resin having a required thickness. For each of the 12 substrates, 12 are the same as the partition plate 4. A partial pattern expression member 6 that expresses a large continuous pattern when arranged is formed so as to be separated, and when the pattern expression member 6 and the residue 7 of the pattern substrate are separated, both of them are necessary. Is attached with adhesive tape 8 to prevent separation and placed. In addition, ward plate 4
Then, the pattern substrate 6 may be used by selecting one having a required thickness from the foamed resin having various thicknesses within a range of about 5 to 200 mm.

In this embodiment, the pattern expressed by arranging twelve pattern substrates 5 in four rows in the vertical direction and three rows in the horizontal direction is the mountain wave including Mt. Fuji, the sea below it, the boat floating in the sea, and the two above the sky. It is a pattern of a landscape consisting of three clouds, and in the embodiment shown in FIGS. 1 to 4, mountain waves above the coastline, a boat in the sea, two clouds are covered by the wall 3
In order to express as a concave pattern 9 on the surface of the pattern substrate, the mountain wave portion, the boat portion, and the cloud portion above the coastline on the pattern substrate are designated as the pattern expressing member 6, and the other portions are designated as the residue 7. On the contrary, in the embodiment of FIGS. 5 to 8, the surface of the wall body is made to have a convex pattern 10, so that the mountain wave portion above the coastline on the pattern substrate,
The boat part and the cloud part are the residues 7, and the other parts are the pattern expression members 6.

Then, one pattern substrate 5 is overlaid on the partition plate 4 at a predetermined position so that the pattern can be expressed, and the pattern expression member 6 is fixed on the partition plate 4 by adhesion, nailing, or the like.
Remove the residue 7.

Then, a curable fluid material C such as ready-mixed concrete was placed between both mold plates 1 and 2, and after hardening, fixed to the mold plate, the partition plate fixed to the inner surface of the front mold plate, and this. By removing the pattern expressing member, in the embodiment shown in FIGS. 1 to 4, the mountain wave portion, the boat portion and the cloud portion above the coastline can form a concave pattern 9 recessed from the surface 3 ′ of the wall body 3. In the embodiment shown in FIGS. 5 to 8, the convex pattern 10 in which they are the surface of the wall can be formed.

The curable fluid material to be placed may be resin concrete or mortar in which resin is used instead of cement, concrete or mortar in which various fibers are mixed, or gypsum or the like, in addition to normal cement and mortar obtained by normal cement.

Then, on the surface of the pattern expressing member 6 fixed on the partition plate, a pattern or pattern 11 is formed by carving it shallower than the thickness of the pattern substrate, or a rough surface 12 is formed by scraping the surface with an appropriate tool such as a brush. However, it is possible to diversify the designs and patterns.

The partition plate 4 and the pattern substrate 5 are optimally made of a foamed resin, which is lightweight and easy to process, but veneer plywood or other plates may be used.

Further, the pattern substrate 5 does not need to have a constant thickness, and one or a plurality of pattern substrates may be thin, and the remaining pattern substrates may be thick. In short, the thickness of the pattern substrate to be used may be determined according to the projections and depressions of the three-dimensional pattern to be expressed.

<Effects of the Invention> As is clear from the above, according to the present invention, the partition plates 4 of the same shape and the same size are fixed and spread on the inner surface of the front formwork plate 2 in a predetermined arrangement, and the partition plates A pattern substrate 5 having the same shape and the same size as that of the pattern expression member 6 so as to be separated from each other.
Since the pattern expression member 6 is fixed on the partition plate 4 and the residue 7 is removed, each pattern expression member 6 can be accurately positioned and fixed on the partition plate 4, and the intended pattern can be formed on the wall body. Can be accurately reproduced on the surface of. By selecting the pattern expressing member 6 and the residue 7, the pattern can be formed on the surface of the wall body as concave or convex, and the degree of the concave or convex is determined by the thickness of the pattern substrate. Can be used to create shaded three-dimensional patterns.

In addition, the division board and the board to be the pattern board are usually 90 cm x 180 cm
It is the most convenient to use because it is sold in the same size.
