  In general, when forming a straight decorative groove in the panel material that is the basis of the panel material, an attempt is made to make it as close to a straight line as possible in consideration of appearance and the like. However, even if the decorative groove is visually close to a straight line, the width of each rectangular (block) pattern of the tile pattern is not uniform, especially when the plurality of panel members are connected in the horizontal direction, the gap ( The difference in the size of the tile pattern) will stand out and the visual appearance will deteriorate. Some panel materials have warpage (within an allowable range) that causes no problem in strength, fit, etc., and the warpage has individual differences. Therefore, in order to secure a uniform vertical width with a straight decorative groove, it is necessary to cut the decorative groove after processing the surface of the panel material flatly in order to eliminate warpage, which increases the number of manufacturing processes and increases efficiency.

  Preferred embodiments of the present invention will be described below with reference to the drawings.

  As FIG. 6 shows, the panel material (refer FIG. 1) 1 which concerns on this embodiment is connected in the horizontal direction H in each floor, and comprises the outer wall 51 of buildings 50, such as an industrialized house. In the surface 1a of the panel material 1 which is the surface on the outdoor side when the outer wall 51 is configured, a linear lateral groove (hereinafter referred to as “decorative groove”) cut in the horizontal direction H, that is, the connecting direction of the panel material 1 is provided. 3 and a grid-like pattern (tile pattern) is formed by the intersection of linear longitudinal grooves (hereinafter referred to as “orthogonal grooves”) 5A and 5B cut in the longitudinal direction V orthogonal to the lateral direction H. Therefore, when the plurality of panel members 1 are connected to form the outer wall 51, the tile patterns are continuously connected to form a uniform appearance design as a whole.

  As shown in FIGS. 1, 2, and 3, the panel material 1 according to the present embodiment is made of lightweight cellular concrete (ALC). The ALC panel material 1 is excellent in workability and is advantageous for forming the decorative grooves 3 and the orthogonal grooves 5A and 5B. However, the panel material 1 made of other materials may be used.

  When used for the outer wall 51 of an industrialized house, the panel material 1 is prepared by standardizing several variations of width dimensions based on the module of the building 50. In the case of the panel material 1 according to the present embodiment, the panel material 1 has a rectangular shape, and includes a pair of opposed long side portions 1b and a pair of opposed short side portions 1c. When the panel material 1 is connected, the long side 1b is vertical, the short side 1c is horizontal, and the long side (connecting part) 1b is connected in the horizontal direction H. The joint portion 52 (see FIG. 4 and FIG. 6) is configured in association with the portion (connecting portion) 1b.

  A plurality of decorative grooves 3 cut in a line shape in the horizontal direction H are formed on the surface 1 a of the panel material 1. The decorative grooves 3 are arranged side by side at substantially equal intervals in the vertical direction V.

  As shown in FIG. 2, the decorative groove 3 has a V-shaped cross section, and the depth Da of the decorative groove 3 is formed to be non-uniform in the lateral direction H within a predetermined range. Further, the width Wa of the decorative groove 3 is also formed to be non-uniform in the lateral direction (see FIG. 1) within a predetermined range. Note that the unevenness in the horizontal direction means that variation occurs when the depth Da of the decorative groove 3 and the width Wa of the decorative groove 3 are measured at several different positions in the horizontal direction H.

  On the surface 1 a of the panel material 1, a plurality of orthogonal grooves 5 </ b> A and 5 </ b> B are linearly cut in the vertical direction V and formed in the horizontal direction H at substantially equal intervals.

  The three orthogonal grooves 5A formed in the intermediate portion (the inner portion that is not the end) of the panel material 1 are substantially trapezoidal in cross section, specifically, an inclined surface having a steep slope with the bottom surface 5a of the orthogonal groove 5A. It has a shape in which an inclined surface 5c having a gentle slope is interposed between the inclined surface 5b and 5b. Further, the orthogonal groove 5B formed in the long side portion 1b is substantially the same as the orthogonal groove 5A in the intermediate portion by being combined with the orthogonal groove 5B of the long side portion 1b of the other panel material 1 connected in the horizontal direction H. It is comprised so that it may become a cross-sectional shape.

  Unlike the decorative groove 3, the depth of the orthogonal grooves 5 </ b> A and 5 </ b> B and the width of the orthogonal grooves 5 </ b> A and 5 </ b> B are not formed so as to be intentionally nonuniform in the vertical direction V. That is, the depth Db of the orthogonal grooves 5A and 5B is about 9 mm, and the depth Dc of the inclined surface portion having a gentle gradient is about 3 mm. The width Wb of the orthogonal groove 5A and the width Wb when the orthogonal grooves 5B are attached to each other are about 25 mm, and the width Wc of one inclined surface portion is about 3 mm.

  A rectangular block-shaped non-cutting portion (hereinafter referred to as “rectangular surface portion”) 7 is formed in the vertical direction on the entire surface 1a of the panel material 1 by forming a plurality of decorative grooves 3 and a plurality of orthogonal grooves 5A, 5B. A tile-like design is formed regularly in the V and horizontal directions H.

  The rectangular surface portion 7 is a rectangular remaining portion of the surface 1a of the panel material 1 after forming the decorative groove 3 and the orthogonal grooves 5A, 5B intersecting each other. Accordingly, the rectangular surface portion 7 is defined by the pair of facing decorative grooves 3 and the pair of facing orthogonal grooves 5A, or the orthogonal grooves 5A, 5B, and the interval between the pair of facing decorative grooves 3; That is, the vertical width Lw has a nonuniform fluctuation.

  Next, the manufacturing method of the panel material 1 which concerns on this embodiment is demonstrated. The panel material 1 is made of ALC. First, the foamed and expanded block body is cut into a predetermined size using a piano wire or the like in a semi-cured state to form a plate-like panel material 2, and then autoclaved (panel) Material formation process).

  Next, the cut groove forming process is executed on the cured panel material 2 obtained in the panel material forming process to form the decorative grooves 3 and the orthogonal grooves 5A and 5B. In the cutting groove forming process, a decorative groove forming process for cutting and forming the decorative groove 3 and an orthogonal groove forming process for cutting and forming the orthogonal grooves 5A and 5B are executed. Cutting in the decorative groove forming process and the orthogonal groove forming process is performed using a cutting device that is automatically controlled in a factory production line.

  In the panel material forming process, the panel material 2 may be slightly warped which does not affect the performance due to a temperature change (difference in shrinkage between the front surface 1a side and the back surface side). Here, the slight warp that does not affect the performance is, for example, a warp that causes the panel material 2 to be lifted within 1 mm when the panel material 2 having a width of 600 mm is placed on a flat surface.

  Here, for example, when the decorative groove is formed by simply moving the cutting blade laterally as in the conventional method (see Patent Document), if the panel material is lifted from the mounting surface due to warpage, The cutting depth by the blade increases in accordance with the degree of lifting of the panel material, and the width of the decorative groove is widened. On the other hand, when there is no warp, the width of the decorative groove is constant. In other words, if the width of the decorative groove of the panel material expands or is constant depending on the presence or absence of warpage that is an individual difference, the shift of the width of the decorative groove is conspicuous at the joint when connecting a plurality of panel materials, There is a possibility that the appearance design will deteriorate.

  On the other hand, according to the cutting groove forming step according to the present embodiment, it is possible to form the decorative groove 3 that can prevent the appearance design from being deteriorated. The reason will be described in detail focusing on the decorative groove forming step.

  When the cross-sectional shape of the decorative groove 3 is V-shaped in the decorative groove forming step, the decorative member 3 has a rotation axis S in the normal direction N of the placement surface B on which the panel material 2 is placed, and the panel material 2 is rotated by rotation. A cutting blade C capable of forming a conical hole is used. As shown in FIG. 5, in the decorative groove forming step, the surface 1 a of the panel material 2 is cut by moving the cutting blade C in the horizontal direction H while reciprocating the cutting blade C in the rotation axis direction. A plurality of V-shaped decorative grooves 3 are formed. In this case, the width of the decorative groove 3 increases as the cutting depth by the cutting blade C increases.

  In this decorative groove forming step, the cutting blade C is moved so as to draw a trajectory Ha in which the separation distance of the cutting blade C with respect to the mounting surface B changes at a constant period, and as a result, the width H of the decorative groove 3 is set in the lateral direction H. Make changes. For example, the cutting blade C is moved so as to draw a sine curve having a predetermined amplitude in a side view, or is moved so that the cutting depth is randomly changed within the predetermined amplitude.

  As described above, the decorative groove 3 is formed by moving the cutting blade C in the lateral direction H while reciprocating in the rotation axis direction, thereby varying the width of the decorative groove 3 regardless of whether the panel material 2 is warped or not. As a result, the vertical width Lw of the rectangular surface portion 7 becomes non-uniform and fluctuations are formed (see FIG. 5B).

  For example, when the surface of the panel material 2 is completely flat, the depth Da of the decorative groove 3 is in the range of 6 mm to 6.5 mm, and the width Wa of the decorative groove 3 is wavy in the range of 22 mm to 24 mm. Set to Here, when considering the warp described above, the depth Da of the decorative groove 3 is in the range of 6 mm to 7.5 mm, and the width Wa of the decorative groove 3 varies in the range of 22 mm to 28 mm. The fluctuation range is 2 mm to 6 mm.

  Even if the width of the decorative groove 3 fluctuates, the linear deepest portion of the decorative groove 3 is kept in a straight line when the surface 1a of the panel material 1 is visually observed, and the other panel materials 1 connected to each other. There will be no deviation. That is, since the center line is not blurred, the decorative groove 3 does not appear to meander even if the width varies slightly. As a result, the tile-like design of the rectangular surface portions 7 arranged in an orderly manner is maintained.

  Further, in the orthogonal groove forming step, it is not necessary to intentionally form the orthogonal grooves 5A and 5B so that the depth and width are intentionally non-uniform in the longitudinal direction V. For example, the orthogonal groove forming step is used in the decorative groove forming step. The direct acting grooves 5A and 5B may be formed by linearly moving the cutting blade C in the vertical direction.

  As described above, in the panel material 1 according to the present embodiment, the vertical width Lw of the rectangular surface portion 7 has uneven fluctuation in the horizontal direction H, and the orthogonal groove 5B orthogonal to the decorative groove 3 is a joint. 52. Therefore, in the case where a plurality of panel materials 1 are connected, the displacement between the adjacent rectangular surface portions 7 with the orthogonal groove 5B (or joint portion 52) interposed therebetween is not noticeable (see FIG. 4A). Accordingly, it is possible to improve the appearance design when the plurality of panel materials 1 are connected in the horizontal direction H, and as a result, it is possible to improve the appearance design of the building 50 having the outer wall 51 in which a plurality of panel materials 1 are connected.

  Here, Fig.4 (a) shows the aspect which connected the panel material 1 which concerns on this embodiment to the horizontal direction H, and the fluctuation | variation is not formed in the rectangular surface part in FIG.4 (b), (c). The aspect which connected the panel materials 100A and 100B which concern on a reference example to the horizontal direction is shown. 4B is a plan view, and FIG. 4C is a cross-sectional view taken along the line cc of FIG. 4B.

  As shown in FIGS. 4B and 4C, in the panel materials 100A and 100B according to the reference example, the width of the decorative groove varies only by the floating of the panel materials 100A and 100B from the placement surface due to warping. However, when the panel material 100A with the warped end and the panel 100B without the warp are connected, the difference in the width of the decorative groove (the size of the rectangular surface portion 101) becomes conspicuous at the joint. On the other hand, according to the panel material 1 which concerns on this embodiment, the shift | offset | difference of the width | variety of the decorative groove 3 (vertical width Lw of the rectangular surface part 7) becomes inconspicuous, and it is advantageous to the improvement of an external appearance design property.

  Further, in the present embodiment, the decorative groove 3 can form a conical hole portion by rotation and can move in the lateral direction while reciprocating the cutting blade C that can reciprocate in the rotation axis S direction in the rotation axis S direction. It is formed by moving in the (joining direction) H, and the decorative groove 3 has a V-shaped cross section and has a different depth in the lateral direction H. As a result of adopting this configuration, the fluctuation of the vertical width Lw of the rectangular surface portion 7 can be easily realized by reciprocating while moving the cutting blade C in the horizontal direction H.

  Further, the panel material 1 is made of ALC, and ALC is excellent in workability, which is advantageous for forming fluctuations of the rectangular surface portion 7.

  Moreover, according to the manufacturing method of said panel material 1, the panel material 1 in which the vertical width Lw of the rectangular surface part 7 has nonuniform fluctuation | variation in the horizontal direction (connection direction) H can be manufactured easily.
