Description

  The present invention relates to a wall panel used as a wall material of a building or a workpiece, and more particularly to a wall panel made of an extruded plate having an uneven portion.

2. Description of the Related Art Conventionally, as a wall panel used for an outer wall of a building, there is a panel made of a cement-based extruded plate. The seed wall panel is manufactured by mixing inorganic fibers, cement, water, and the like, and extruding the mixture. Then, after the extrusion molding, the panel surface is subjected to a polishing treatment in order to remove Eflo (calcium hydroxide) and the like adhering to the panel surface. As the polishing means in this case, for example, as described in Patent Document 1, a rotary polishing body in which hard abrasive grains are fixed to the outer peripheral surface of a columnar body is used.
JP 06-126603 A

  In the surface treatment using the rotary polishing body described in Patent Literature 1, when the surface shape of the wall panel is flat, it is possible to remove deposits on the panel surface by the polishing process. When the surface shape of the substrate has irregularities, the polishing treatment cannot be efficiently performed on the concave portions on the panel surface, and it becomes difficult to remove the deposits on the surface of the concave portions. Therefore, deposits such as Efro remain on the surface of the wall panel, and the remaining portions become white and adhere. Further, in the surface treatment using the polishing means, since light rays hitting the treated surface are reflected without interfering with each other, a shadow of light is generated on the panel surface, which adversely affects visual recognition. was there.

  Therefore, there is a technical problem to be solved in order to remove the effluent and the like on the surface of the wall panel having the uneven shape portion and to prevent the shadow of light from being generated on the surface of the wall panel. The idea is to solve the problem.

  The present invention has been proposed in order to achieve the above object, and in a wall panel made of a cement-based extruded plate having an uneven portion, the surface of the uneven portion of the wall panel is subjected to shot blasting or A fine uneven surface is formed by sandblasting, and the fine uneven surface provides a wall panel having a surface roughness of such a degree that light is irregularly reflected and mutually erased.

  According to this configuration, by forming the fine uneven surface on the surface of the wall panel by shot blasting or sand blasting, even when the wall panel has the uneven shape portion, a shot blasting machine or a sand blasting machine is used. The abrasive (injection material) injected from the machine reaches the recess of the wall panel, and the surface treatment with the abrasive can be performed.

  Further, since the surface roughness of the fine uneven surface is formed to such an extent that light rays irregularly reflected on the fine uneven surface interfere with each other and erase each other, no shadow of light is generated on the surface of the wall panel. .

  In the present invention, since the abrasive injected from the shot blasting machine or the sand blasting machine reaches the concave portion of the uneven portion, the same as the surface of the convex portion, even if the wall panel has a shape having the uneven portion. In addition, the surface of the concave portion can be properly subjected to the shot blasting or the sand blasting process, so that unnecessary substances such as the Efro present on the surface of the convex portion and the concave portion can be surely removed.

  In addition, since a large number of light beams reflected on the fine uneven surface of the panel cancel each other, a light and shade pattern of light shadow does not occur on the surface of the wall panel, thereby improving the visual aesthetics of the wall panel.

  The present invention relates to a wall panel made of an extruded plate having an uneven portion, wherein a fine uneven surface is formed by shot blasting or sand blasting on the concave surface of the convex portion of the wall panel. The surface roughness was achieved by finishing to such an extent that the light rays were irregularly reflected and canceled each other.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In the figure, reference numeral 1 denotes a wall panel used as a building material such as an outer wall or a partition wall, which has been unit-produced in a factory in advance. The wall panel 1 has a plurality of hollow portions 2, 2,... Extending in parallel in the lateral direction, and is formed in a lightweight hollow structure. The wall panel 1 has required strength, weather resistance, fire resistance, earthquake resistance, and the like, and is attached to columns, beams, and the like on the building skeleton side by bolts via angles (not shown).

  The wall panel 1 is made of a cement-based extruded plate having an uneven portion 3 and has both an aesthetic appearance and a design property of an uneven pattern. Therefore, the wall panel 1 itself can be used as it is as a decorative board.

  On the surface of the wall panel 1, a plurality of concave grooves (recesses) 4, 4,... And a plurality of ridges (convex portions) are provided at predetermined intervals in the vertical direction of the wall panel 1 (vertical direction in FIG. 1). ) Are provided alternately to form the uneven portion 3.

  The wall panel 1 is manufactured, for example, according to the following extrusion molding method. That is, the inorganic fiber, cement, admixture, and water are mixed at a predetermined ratio, and the mixture is injected into an extruder and extruded. Next, the extruded product is cured and cured for a predetermined time under predetermined conditions, and then cut to produce the wall panel 1 having a predetermined size.

  Thereafter, a surface treatment is performed by shot blasting or sand blasting in order to remove extraneous matters such as efro and scale existing on the surface of the wall panel 1. That is, by using a shot blasting machine or a sand blasting machine, a grinding material (injection material) is sprayed onto the surface of the uneven portion 3 of the wall panel 1 to form a fine uneven surface on the surface of the uneven portion 3. In this case, the surface roughness of the fine uneven surface is such that light rays incident on the fine uneven surface are irregularly reflected in multiple directions, interfere with each other, and cancel each other out.

  According to the present embodiment, since the wall panel 1 is subjected to surface treatment by injecting an abrasive by shot blasting or sand blasting, the abrasive is applied to the ridges 5, 5,... Of the wall panel 1. , As well as the surfaces of the grooves 4, 4,..., And an effective surface treatment is performed. Therefore, even when the shape of the wall panel 1 has the uneven portion 3, the intended surface treatment can be surely performed, and the Efro and the like adhering to the surface can be removed. Examples of the type of the abrasive include non-ferrous metals such as cast iron, stainless steel, aluminum, zinc, and copper, resins such as alumina, carbon silicon, glass, nylon, polycarbonate, acrylic resin, urea resin, and melamine resin, apricot, and walnut. , Seeds such as peaches and those obtained by grinding corn cores, sands such as silica sand, ceramics, beads, zirconia, slag, calcium carbonate, baking soda, polycarbonate and the like, and the shape of the abrasives , Spherical, acute angle and cut wire shapes.

  Further, according to the present embodiment, a fine uneven surface is formed on the surface of the wall panel 1 by shot blasting or sand blasting, and light rays incident on the fine uneven surface are irregularly reflected in multiple directions and refracted mutually. Since the light beams interfere with each other, a light shadow does not occur at various places on the surface of the wall panel 1 due to the light beam canceling action. Therefore, the appearance of the wall panel 1 is improved as compared with the related art, and the product value of the wall panel 1 is improved.

  The present invention should not be limited to the above-described embodiment. May be formed.

  The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified one.
