JP 2010-167334 A

  This invention makes it a subject to apply the above-mentioned inkjet printing to the concrete block for construction, and to obtain the concrete block using the texture peculiar to concrete.

The present invention has been made to solve the above-described problems, and is characterized by the following.
(Claim 1)

The invention described in claim 1 is characterized by the following points.
(Claim 1)

In other words, the concrete block printing method according to claim 1 is a concrete block printing method for inkjet printing a print image on a face shell surface of a concrete block, and a zero slump concrete is put into a formwork. A concrete block manufactured by immediate demolding after compaction was used, and at least one of shot blasting, sand blasting, polishing, cutting and bishan processing was applied to the face shell surface before ink jet printing. It is characterized by.
(Claim 2)

  The invention described in claim 2 has the following features in addition to the features of the invention described in claim 1 described above.

That is, the area on which the ink jet printing is performed is 5 to 30% of the face shell surface.
(Claim 3)

  A third aspect of the present invention is a concrete block printed using the concrete block printing method according to the first or second aspect.

  The present invention is as described above, and uses a concrete block (a concrete block obtained by so-called “immediate demolding”) manufactured by immediately demolding after putting zero slump concrete into a mold and compacting it. For this reason, compared with the block manufactured by pouring, the face shell surface is rough, and a unique texture can be obtained.

  In addition, at least one of shot blasting, sand blasting, polishing, cutting, and bishan processing was performed on the face shell surface before ink jet printing was performed on the face shell surface. For this reason, an expression different from a simple rough surface can be obtained.

  That is, when shot blasting, sand blasting, cutting processing, and Vishan processing are performed, a surface cement paste layer is taken and a part of the internal aggregate is exposed. At this time, if the color of the aggregate to be used is changed, a color change is added to the unevenness, resulting in a heavy texture. If printing is performed on such a processed surface, an image utilizing the texture can be obtained in combination with inkjet printing.

  Moreover, when a grinding | polishing process is performed, a part of internal aggregate will be exposed, the color will also be visible, and a glossiness can be given to a concrete surface. By printing on such a processed surface, it is possible to obtain a surface utilizing a texture different from that of shot blasting or sand blasting.

  In addition, as for the area which performs inkjet printing, it is desirable that it is 5 to 30% of a face shell surface. More preferably, it is 5 to 20%. That is, in order to take advantage of the texture of the processed concrete block, the effect is not obtained if there are too many printed surfaces. Further, by reducing the printing range, the amount of ink used can be reduced, and the manufacturing cost can be reduced.

It is (a) top view, (b) front view, (c) side view of a concrete block. (A) The figure which shows a to-be-photographed object, (b) It is a front view of the concrete block which gave printing.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a view showing a concrete block 10 according to the present embodiment. This concrete block 10 is manufactured by instantly demolding after putting zero slump concrete into a formwork and compacting it (a concrete block obtained by so-called “immediate demolding”), 190 mm long and 398 mm wide It has become the size.

  As shown in FIG. 1, the concrete block 10 has face shell surfaces 10a on the front and back sides. The face shell surface 10a is subjected to at least one of shot blasting, sand blasting, polishing, cutting, and bishan processing, and a part of the internal aggregate is exposed.

  In the present embodiment, the entire face shell surface 10a is subjected to at least one of shot blasting, sand blasting, and polishing. However, the present invention is not limited thereto, and shot blasting is performed only on a part of the face shell surface 10a. At least one of sandblasting and polishing may be performed. If only a part is processed, the width of the design can be expanded by the difference in texture between the non-processed surface and the processed surface.

  In the present embodiment, inkjet printing is performed on the face shell surface 10a using an image obtained by photographing the subject A as shown in FIG.

  The subject A is obtained by arranging a plurality of stones A1 and providing joints A2 between the stones A1. The subject A is photographed with a digital camera or the like, the photographed image is taken into a personal computer or the like, and trimmed with image editing software or the like to obtain a printed image.

  In this embodiment, only the portion of the joint A2 is extracted from the photographed image and used as a print image. That is, as indicated by the print area P in FIG. 2B, only the joint A2 is printed.

  The print area P is desirably 5 to 30% of the face shell surface 10a. More preferably, it is 5 to 20%. In this embodiment, 4 × 5 = 20 stones A1 of 41.5 × 73.2 = 3037.8 mm 2 are arranged on the face shell surface 10a of 190 × 398 = 75620 mm 2, It is designed to have a joint A2 having a width of 8 millimeters between the stones A1. For this reason, the area of the joint A2 (that is, the printing region P) is 14864 mm 2, which is about 19.7% of the face shell surface 10a.

  According to the embodiment, since the concrete block 10 obtained by so-called “immediate removal” is used, the face shell surface 10a is rougher than a block manufactured by pouring, and a unique texture can be obtained. .

  Moreover, at least one of shot blasting, sand blasting, polishing, cutting, and bishan processing is performed on the face shell surface 10a before ink jet printing is performed on the face shell surface 10a. For this reason, an expression different from a simple rough surface can be obtained.

  For example, when shot blasting, sand blasting, cutting, or bishan processing is performed, a cement paste layer is removed from the surface, and a part of the internal aggregate is exposed. At this time, if the color of the aggregate to be used is changed, a color change is added to the unevenness, resulting in a heavy texture. If printing is performed on such a processed surface, an image utilizing the texture can be obtained in combination with inkjet printing.

  Moreover, when a grinding | polishing process is performed, a part of internal aggregate will be exposed, the color will also be visible, and a glossiness can be given to a concrete surface. By printing on such a processed surface, it is possible to obtain a surface utilizing a texture different from that of shot blasting or sand blasting.

  Moreover, since the area to which inkjet printing is performed is 5 to 30% of the face shell surface 10a, more preferably 5 to 20%, the processed surface is exposed at a portion where printing is not performed. Thereby, it can be set as the design which utilized the texture of the concrete block 10 which processed. Further, by reducing the printing range, it is possible to reduce the amount of ink used, and the printing cost can be reduced.
