Description

  The present invention relates to a wall material having an uneven pattern on the surface.

  Conventionally, an inorganic building board made of a hydraulic material such as cement has been widely used as a wall material to be constructed in a building such as a house. And in such a building board, with the aim of improving the designability, an uneven pattern 5 is formed on the surface of the building board by mold molding or the like, and an annual ring pattern (wood grain pattern) as in natural wood is formed. It is being reproduced. FIG. 3 shows a cross-sectional side view of a wall material (building board) having an uneven pattern 5 on the surface. As shown in FIG. 3 (a), a plurality of concave portions 2 and convex portions 3 are formed on the wall material surface over substantially the entire length in the width direction to form a concave / convex pattern 5, and the concave / convex pattern 5 is formed. The dense region A and the sparse region B are alternately and repeatedly formed, so that a natural wood grain pattern appears on the surface of the wall material. In this case, the heights H (dimensions from the lower end portion of the wall material to the tip of the convex portion) of the plurality of convex portions 3, 3,. (See FIGS. 3A and 3B).

  The wall material on which the concavo-convex pattern 5 is formed as described above is generally produced in a factory, transported to a residential building site through a physical distribution route, and then cut and applied as a housing outer wall. Is. Then, in transporting the wall material, as shown in FIG. 3C, the surface of the two wall materials is overlapped and packed so as to face each other so that the mounting state becomes more stable. In addition, pallets may be stacked on the wall material placed on the upper side. For this reason, when subjected to stress such as vibration during transportation or handling during construction, an impact due to friction or the like between the uneven surface may occur. At this time, since there is a possibility that the unevenness forming surface is damaged or cracked, various methods for preventing this have been proposed. For example, when the concavo-convex forming surfaces of two wall materials are overlapped with each other, a cushioning material such as the interleaf paper 20 is sandwiched between them, thereby preventing the concavo-convex forming surface from being damaged or cracked. There is a method (see, for example, Patent Document 1).

JP 2005-41546 A

  However, just inserting the interleaf paper 20 between the two wall materials as described above does not necessarily prevent the occurrence of scratches and cracks. In particular, in FIG. 3, in the region A where the uneven pattern 5 is densely formed by shortening the uneven pitch, the releasability from the mold at the time of mold molding is taken into consideration. The tip is tapered and pointed. In the convex portion 3 having a tapered tip, cracks and chipping frequently occur even if the slip sheet 20 is inserted between the two upper and lower wall materials. Further, as described above, since the convex portions 3 are all formed with the same height H, when the concave and convex formation surfaces are overlapped, the convex portion 3 in the region A that is vulnerable to a load such as impact is also included in the interleaf 20. In some cases, the surface may be damaged due to friction or impact caused by the contact. If the surface is damaged in this way, the designability after the wall material is constructed may be deteriorated. Therefore, in the wall material that has been delicately patterned with the concavo-convex pattern 5 or the like, there has been a demand for a wall material that is less likely to be damaged due to impact during loading or vibration during transportation and that is less likely to deteriorate in design. .

  The present invention has been made in view of the above points, and even when a plurality of wall materials are stacked, even if the unevenness forming surfaces formed on the surface are opposed to each other, damage to the surface is suppressed. It is an object of the present invention to provide a wall material in which designability is unlikely to deteriorate.

The wall material according to the present invention is a wall material in which a plurality of recesses are formed on the surface of a ceramic base material, and the surface height of a high-density region in which the interval between the adjacent recesses is formed narrow. , Ri is formed lower than the surface height of the low-density region where the spacing between adjacent concave portions is formed wider formed, the convex portion of the high-density region is characterized pointed shape der Rukoto tapered .

  In addition, it is preferable that the high-density regions are arranged so that the high-density regions are substantially opposed to each other when stacking a plurality of substrates with the surfaces of adjacent substrates facing each other.

  In addition, the concave portion is formed as a pseudo-annular ring, the surface of the base material is formed in a wood grain by the plurality of pseudo-annular rings, and the high-density region is formed by narrowing the interval between the adjacent pseudo-annular rings. It is preferable.

  In the wall material of the present invention, breakage such as chipping or cracking of the surface on which the concave / convex pattern is formed is suppressed, and design properties are unlikely to deteriorate.

An example of embodiment of the wall material of this invention is shown, (a) is the sectional view in side view, (b) is an enlarged view of a part of (a), (c) is the surface of the wall material overlapped It is a sectional view in side view when loaded. An example of another embodiment of the above is shown, (a) is a side sectional view thereof, (b) is an enlarged view of a part of (a), and (c) is stacked with the surfaces of wall materials stacked. FIG. A prior art example is shown, (a) is a sectional view in side view, and (b) is an enlarged view of a part of (a). (C) is a sectional side view when the surfaces of wall materials are stacked and stacked.

  Hereinafter, modes for carrying out the present invention will be described.

  FIG. 1 is a side cross-sectional view showing an example of an embodiment of a wall material of the present invention. As shown in FIG. 1A, one surface (front surface) of a base material 1 has a plurality of convex portions. 3 and a plurality of recesses 2 are formed over substantially the entire length of the substrate 1, and a concavo-convex pattern 5 is formed. The concavo-convex pattern 5 serves as a pattern of the base material 1, and design properties are imparted to the surface of the base material 1. The shape of the substrate 1 is not particularly limited. For example, a flat plate having a concavo-convex pattern 5 formed on the surface thereof can be used.

  The concavo-convex pattern 5 includes a region A in which the interval between the adjacent recesses 2 and 2 is formed narrow and a region B in which the interval between the adjacent recesses 2 and 2 is formed wide. That is, on the surface of the base material 1, there were a high pattern density area A (hereinafter referred to as a high density area A) and a low pattern density area B (hereinafter referred to as a low density area B). It has become a thing.

  And in the base material 1, the low density area | region B is arrange | positioned between the two high density areas A and A. As shown in FIG. A groove 15 is formed at one end of the high density region A (on the opposite side to the low density region B), and the groove 15 is formed between the two high density regions A and A. The groove 15 is formed deeper than the depth of the recess 2.

As shown in FIG. 1 (b), in the wall material of the present invention, the interval T _A between the recess 2, 2 adjacent in the high-density region A, the interval T between recesses 2, 2 adjacent in the low-density region B _It is shorter than _B. Specifically, the interval _{T A} between the recess 2, 2 adjacent in the high-density region A may be in the range of 1 to 30 mm, the interval _{T B} between the recess 2, 2 adjacent in the low-density region B Can be in the range of 5-100 mm. In the plurality of recesses 2, 2,... In the high density region A, the intervals T _A between the adjacent 2, 2 are all substantially the same size, and similarly, there are a plurality of low density regions B. recesses 2,2 in., spacing _{T B} between the recess 2 and 2 is also a dimension of all substantially the same.

On the other hand, the width dimension (L _{A in the} drawing) of the convex portion 3 in the high density region _A is also formed shorter than the tip width (L _{B in the} drawing) of the convex portion 3 in the low density region B. . Specifically, the width L _A of the tip portion of the protruding portion 3 in the high-density region A can in the range of 1 to 10 mm, the width L _B of the tip portion of the protruding portion 3 in the low-density region B, 10 Can be in the range of ~ 100 mm. In addition, a plurality of convex portions 3, 3,... Present in the high-density region A have substantially the same width L _A , and similarly, a plurality of convex portions 3 that exist in the low-density region B, 3 width of ... the tip L _B is also a dimension of all substantially the same. As described above, the width L _A of the tip portion of the protruding portion 3 in the high-density region A is formed shorter, it has become a pointed shape tapered.

  Although the depth dimension of the recessed part 2 is not specifically limited, For example, it can be set to 1-4 mm, and the upper surface opening width of the recessed part 2 can be similarly set to 1-30 mm, for example. .

  Since the high-density area A and the low-density area B are configured as described above, when comparing both areas A and B per unit length in the width direction of the substrate 1, the high-density area A On the other hand, the uneven pattern 5 is formed finer than the low density region B, and a finer pattern appears.

In the wall material of the present invention, the surface height (H _{A in} FIG. _1B ) in the high density region _A is formed lower than the surface height in the low density region B (H _{B in} FIG. 1B). ing. Here, H _A and H _B in each high-density region A and the high-density region B, and those from the tip of the convex portion 3 refers to the shortest distance to the lower end portion of the substrate 1. In the high density region A, a plurality of convex portions 3 are provided, but in the embodiment of FIG. 1, in any of the convex portions 3, the distance from the tip of the convex portion 3 to the lower end portion of the substrate 1 (that is, H _A ) is the same. Similarly, in any convex portion 3 in the low density region B, the distance from the tip of the convex portion 3 to the lower end portion of the substrate 1 (that is, H _B ) is the same. Furthermore, the plurality of high-density areas A on the surface of the substrate 1 have the same surface height H _A , and the plurality of low-density areas B have the same surface height H _B.

When the surface height H _A of the high-density region _A is formed lower than the surface height H _B of the low-density region B, two base materials are interposed via the interleaf 20 as shown in FIG. Even when the surfaces 1 and 1 are stacked so as to face each other, contact of the unevenness forming surface of the high-density region A with the interleaf 20 is prevented. The convex part 3 of the high-density area A, which is easy to break due to the tapered shape in this way, is prevented from contacting the interleaf paper 20 at the time of stacking, so that the unevenness forming surface of the high-density area A is loaded. Therefore, damage such as chipping or scratching can be suppressed. On the other hand, the convex portion 3 of the low density region B is not easily damaged because the tip portion is not tapered, and even if it contacts the interleaf paper 20, there is no problem. Thus, the wall material of the present invention, the surface height H _A high-density area A, low-density regions surface height H that is formed lower than the _B of B, breakage of the uneven side of the substrate 1 is suppressed Thus, high designability can be imparted even after construction.

The surface height H _A in the high density region _A is preferably formed to be 0.1 to 2.0 mm lower than the surface height H _B in the low density region B. Can be more reliably prevented.

  Further, in the present invention, when the pair of base materials 1 and 1 are stacked, when the surfaces of the base materials 1 are opposed to each other as shown in FIG. It is preferable that the high-density region A is disposed on the surface of the substrate 1 so as to face each other. In this case, in one high-density region A on one base material 1, at least half of the length in the width direction may be opposite to the high-density region A on the other base material 1. With such a configuration, when a set of base materials 1 and 1 are loaded, the low density region B of one base material 1 and the low density region B of the other base material 1 are substantially opposed to each other. Become.

  Since the wall material has the above-described configuration, even if the surfaces of the two substrates 1 and 1 are stacked so as to face each other, the low density region B of one substrate 1 and the low density of the other substrate 1 are reduced. The density region B overlaps with the interleaf paper 20 interposed therebetween. Therefore, the loading state is more stable, the occurrence of deviation of the base material 1 can be prevented, and the vibration and friction at the time of transporting the wall material are further reduced. It is suppressed. If the two substrates 1 and 1 are stacked so that they face each other, the high density areas A and the low density areas B always face each other, so there is no need to adjust the position during loading. This saves time and shipping.

  A plurality of substrates 1 can be stacked. In this case, the substrates 1 may be stacked so that the concave and convex formation surfaces of the substrates 1 adjacent to each other face each other.

  In the wall material of the present invention, as described above, the concave / convex pattern 5 is formed on the surface of the base material 1 by the plural convex portions 3 and the plural concave portions 2. The appearance of the material 1 as an annual ring pattern is given. Specifically, the recess 2 is formed as a pseudo-annular ring, and by providing the plurality of recesses 2, a plurality of pseudo-annular rings are formed on the surface of the substrate 1 to form an annual ring pattern. Then, by providing a plurality of pseudo annual rings on the surface of the base material 1, the wall material surface is formed in a wood grain (wood grain pattern).

A plurality of the pseudo-annular rings are formed on the surface of the base material 1 as described above, and a more natural-feeling wood grain finish is achieved by narrowing or widening the interval between adjacent pseudo-annular rings. It will be a thing. Then, the distance between the adjacent pseudo annulus gathered narrow pseudo annulus region, the spacing T _A between the recess 2, 2 is also a shortened formed region, and corresponds to the high-density region A in FIG. 1 . That is, in the wall material of the present invention, the high-density region A can be formed by narrowing the interval between adjacent pseudo-annular rings, and conversely, by reducing the interval between adjacent pseudo-annular rings, Region B can be formed.

  Therefore, by adjusting the adjacent pseudo annual ring width, it is possible to form the high-density region A and the low-density region B, and it is also possible to form a natural wood grain. Therefore, with such a wall material, it is possible to easily give a delicate pattern to the surface of the base material 1, and the delicate pattern portion is less likely to be damaged during loading. Sexuality is imparted.

In the wall material of the present invention, the surface height H _A in the high density region _A is formed lower than the surface height H _B in the low density region B, and the surface height HA of the high density region _A is continuous. It may be something that changes so as to be lower.

Specifically, it is as shown in FIGS. In this embodiment, as shown in FIG. 2B, the plurality of convex portions 3 formed in the low density region B is a distance (that is, H from the tip of the convex portion 3 to the lower end portion of the substrate 1). _B ) are formed in the same dimensions. On the other hand, in the high density region A located on both sides of the low density region B, the plurality of convex portions 3 formed in the region are distances from the tip of the convex portion 3 to the lower end portion of the substrate 1 (that is, H _A ) is formed so as to shorten continuously or stepwise as the distance from the low density region B increases. That is, in the wall material of the present embodiment, the low density region B and the high density regions A and A adjacent to the low density region B have a shape in which the surface is formed in a substantially curved shape, and the curved central portion ( The low density region B is located at the maximum height). And as the whole width direction of base material 1, it will be formed in a wave shape. Other configurations are the same as those of the embodiment of FIG.

  Even when configured as described above, similarly to the case of the embodiment of FIG. In this way, contact of the unevenness forming surface of the high-density region A with the interleaf paper 20 is prevented (see FIG. 2C). Therefore, the contact of the unevenness forming surface of the high density region A with the interleaf paper 20 is prevented, and breakage such as chipping or scratching of the unevenness forming surface of the high density region A is suppressed.

  In addition, the height of the high-density area A is lower than that of the low-density area B by continuously changing the height of the high-density area A as in this embodiment. It can be difficult to understand in appearance. For this reason, it is possible to prevent unnecessary shadows from being formed on the surface of the base material 1, and the discomfort in the appearance of the wall material can be alleviated and higher designability can be imparted.

  In the present invention, the base material 1 may be either an inorganic material such as a ceramic base material or a metal base material, or an organic material such as a resin base material. The exterior material of the ceramic base material is used for applications such as wall materials or roof tiles.

  The ceramic base material is produced by blending an inorganic filler, a fibrous material, or the like with a hydraulic glue used as a raw material for an inorganic hardened body, followed by curing and curing. Although it does not specifically limit as a hydraulic glue, For example, 1 type or multiple types of what was chosen from Portland cement, blast furnace cement, blast furnace slag, calcium silicate, gypsum, etc. can be used. In addition, as the inorganic filler, fly ash, microsilica, silica sand, etc., and as the fibrous material, inorganic fibers such as pulp and synthetic fibers, and metal fibers such as steel fibers are used alone or in combination. Can be used.

  The base material 1 can be formed by methods such as extrusion molding, cast molding, papermaking molding, and press molding. Then, a mold having a predetermined shape may be used so that the uneven pattern is formed in this molding. After molding, if necessary, autoclaving, steam curing, and room temperature curing can be performed to produce a ceramic base material having an uneven pattern as an exterior material. The surface of the ceramic base material 1 produced in this way may be sealed with a solvent-based, water-soluble or emulsion-based sealer to adjust the variation in suction into the surface of the base material 1. The sealer used is not particularly limited, but acrylic or latex type sealers can be used. An acrylic or latex organic coating film may be formed on the sealer in order to improve design and durability.

  In addition, as the base material 1, for example, an inorganic board such as a flexible board, a calcium silicate board, a gypsum slag perlite board, a wood piece cement board, a precast concrete board, an ALC board, or a gypsum board can be used.
