Description

  The present invention relates to a building board such as an outer wall material.

  Conventionally, as a construction board, a wide pattern block row in which wide blocks of arbitrary length are arranged side by side and a narrow pattern block row in which narrow blocks of arbitrary length are arranged side by side are arranged alternately above and below via joint grooves. An architectural board having a decorative surface is known (see, for example, Patent Document 1). In this building board, the upper joint groove of the narrow pattern block row is aligned in a horizontal line, and the lower joint groove of the narrow pattern block row is made uneven by shifting up and down every arbitrary length. . As a result, this building board material has an interesting and natural design on the makeup face that balances a feeling of unevenness and a sense of balance.

  Building boards are usually manufactured, packed in multiple sheets, and transported to the construction site in this state. In this case, if the corners of the wide pattern block or the narrow pattern block protrude as in Patent Document 1, the corners of the building board will be lost when the building boards are stacked. The design may be damaged.

  This invention is made | formed in view of said point, and it aims at providing the building board which can suppress damage of the uneven | corrugated pattern on the surface at the time of packing.

The building board according to the present invention is a building board formed by providing a plurality of first ridges and second ridges in parallel in the left-right direction,
The first ridge is formed in a triangular cross section with a first upper slope that is an upper slope and a first lower slope that is a lower slope,
The second ridge is formed in a trapezoidal cross section with a second upper slope that is an upper slope, a flat surface, and a second lower slope that is a lower slope,
The ridgeline formed by the intersection of the first upper slope and the first lower slope of the first ridge with respect to an imaginary straight line that bisects the building board in the vertical direction is located at a location where the ridge line is asymmetric. And
Wherein the first ridge and the second ridge is Ri same height der,
The first upper slope, the first lower slope, the second upper slope, the the second ones widest of the lower slope, and features that you have cut the shaped triangular section are provided in the lateral direction To do.

  ADVANTAGE OF THE INVENTION According to this invention, the damage of the uneven | corrugated pattern on the surface can be suppressed at the time of packing. In other words, when the surfaces of the two building boards with the concavo-convex pattern are stacked and packed, if the top and bottom of these building boards are reversed, the ridgelines of the first ridges do not contact each other. Both corners can be made difficult to chip. Even if the first and second ridges face each other, the ridge line of the first ridge only touches the flat surface of the second ridge and does not catch, so the corner of the first ridge is missing. Can be difficult. Even if the second ridges face each other, only the flat surfaces of the two ridges are in contact with each other, and the second ridges are not caught. In this way, breakage of the uneven pattern on the surface of the building board can be suppressed.

  Embodiments of the present invention will be described below.

  As shown in FIG. 1, the building board 1 according to the present invention is formed in a rectangular shape, and is formed by providing a plurality of first ridges 21 and second ridges 22 in parallel in the left-right direction. The first ridges 21 and the second ridges 22 are both elongated and projecting to the outdoor side of the building board 1. Unless otherwise specified, up, down, left, and right mean directions in a state where the building board 1 is installed as an outer wall material (siding). As will be described later, if the ridge line 4 of the first ridge 21 is located at a predetermined location, the first ridge 21 and the second ridge 22 may be provided regularly, such as alternately. , May be provided irregularly. That is, the first ridges 21 and the second ridges 22 are vertically adjacent to each other, the first ridges 21 and 21 are adjacent to each other vertically, and the second ridges 22 and 22 are adjacent to each other vertically. Or you may. And between the 1st protruding item | line 21 and 2nd protruding item | line 22 adjacent up and down, between the 1st protruding item | lines 21 and 21 adjacent up and down, and 2nd protruding item | line 22 and 22 adjacent up and down In the meantime, the recess 5 is formed, and the uneven pattern 7 of horizontal stripes is formed on the surface of the building board 1. The bottom of the groove 5 may be flat or not flat such as a V-shaped groove. The number of the 1st protruding item | line 21 and the 2nd protruding item | line 22 provided in the surface of the building board 1 is not specifically limited. In addition, the length of the up-down direction of the building board 1 is about 250-1000 mm, the length of the left-right direction is about 300-4200 mm, and thickness is about 5-50 mm.

  The 1st protruding item | line 21 is formed in the cross-sectional triangle shape by the 1st upper slope 201 and the 1st lower slope 211 as shown to Fig.2 (a). The first upper slope 201 is an upper slope, and the first lower slope 211 is a lower slope. The first upper slope 201 and the first lower slope 211 intersect to form the ridgeline 4. The cross-sectional shape of the 1st protruding item | line 21 will not be specifically limited if it is a triangle. The angle formed by the first upper slope 201 and the first lower slope 211 may be an acute angle, a right angle, or an obtuse angle. Although an obtuse angle is less likely to be chipped than an acute angle, in the present invention, since the first ridges 21 are provided at predetermined positions of the building board 1, even an acute angle can be prevented from being chipped. The building board 1 may be provided with a plurality of only one type of first ridges 21 having the same cross-sectional shape, or may be provided with a plurality of types of first ridges 21 having different cross-sectional shapes. . In addition, the length of the base of the triangle of the cross section of the 1st protruding item | line 21 is about 5-20 mm, and height is about 3-30 mm.

  As shown in FIGS. 2B and 2C, the second ridge 22 is formed in a trapezoidal cross section with a second upper slope 202, a flat surface 212, and a second lower slope 222. The second upper slope 202 is an upper slope, and the second lower slope 222 is a lower slope. If the cross-sectional shape of the 2nd protruding item | line 22 is trapezoid, it will not specifically limit. The angle formed between the second upper slope 202 and the flat surface 212 and the angle formed between the flat surface 212 and the second lower slope 222 are right angles or obtuse angles. As shown in FIGS. 2B and 2C, the building board may be provided with a plurality of types of second ridges 22 having different trapezoidal cross-sectional shapes, and one type of second ridge 22 having the same cross-sectional shape. Only a plurality of ridges 22 may be provided. In addition, the length of the upper base of the trapezoid of the cross section of the 2nd protruding item | line 22 is about 3-15 mm, the length of a lower base is about 6-30 mm, and height is about 3-30 mm.

  Here, at least one of the first upper slope 201 and the first lower slope 211 of the first ridge 21 and the second upper slope 202 and the second lower slope 222 of the second ridge 22 is shown in FIG. It is preferable that the notch | incision 51 as shown to the left-right direction of the building board 1 is provided. Thereby, at least any one of the 1st protruding item | line 21 and the 2nd protruding item | line 22 can be divided | segmented up and down by the incision 51, and can be made to look thin. If it does in this way, when the building board 1 is seen from the front, it will become difficult to attach the 1st protruding item | line 21 and the 2nd protruding item | line 22 with it. FIG. 3A shows a specific example in which two cuts 51 are provided on the second upper slope 202 of the second ridge 22. In particular, when the building board 1 is viewed from the front, the most of the first upper slope 201 and the first lower slope 211 of the first ridge 21, the second upper slope 202 and the second lower slope 222 of the second ridge 22. It is effective to provide the notch 51 in a wide thing. The cut 51 may be provided on the flat surface 212 of the second ridge 22. The length of the cuts 51 in the left-right direction is the same as the lengths of the first ridges 21 and the second ridges 22, but the depth and number of the cuts 51 are not particularly limited.

  Further, instead of the notch 51, at least one of the first upper slope 201 and the first lower slope 211 of the first ridge 21, the second upper slope 202 and the second lower slope 222 of the second ridge 22, The rib-like protrusions 52 as shown in FIG. 3 (b) may be provided elongated in the left-right direction of the building board 1. Thereby, like the case of the notch 51, at least any one of the 1st protruding item | line 21 and the 2nd protruding item | line 22 can be divided | segmented up and down by the rib-shaped protrusion 52, and can be made to look thin. FIG. 3B shows a specific example in which two rib-like protrusions 52 are provided on the second upper slope 202 of the second ridge 22. Similarly to the case of providing the notch 51, the width of the first upper slope 201 and the first lower slope 211 of the first ridge 21, the second upper slope 202 and the second lower slope 222 of the second ridge 22 is the widest. It is effective to provide the rib-like protrusions 52 on a wide object. The rib-like protrusions 52 may also be provided on the flat surface 212 of the second ridge 22. The length of the rib-like projections 52 in the left-right direction is the same as the length of the first ridges 21 and the second ridges 22, but the height and number of the rib-like projections 52 are not particularly limited.

  And in this invention, as shown in FIG. 1, it is located in the location where the ridgeline 4 of the 1st protruding item | line 21 becomes asymmetric with respect to the imaginary straight line 3 which bisects the building board 1 up and down. Yes. That is, the ridgeline 4 of the first ridge 21 provided in the upper half of the building board 1 and the ridgeline 4 of the first ridge 21 provided in the lower half of the building board 1 are relative to the straight line 3 described above. It is not located in a line-symmetric part. The ridgeline 4 of the first ridge 21 and the straight line 3 do not overlap. When installing a plurality of building boards 1 up and down, male fruit 8 and female fruit 9 as shown in FIG. 4 (a) may be provided above and below each building board 1, respectively. 3 passes through the center of the full length in the vertical direction of the building board 1 including the male fruit 8 and the female fruit 9. When the building board 1 is inverted up and down with the straight line 3 as an axis, the ridge lines 4 of the first ridges 21 do not overlap. If the 1st protruding item | line 21 is provided in such a position, the arrangement | sequence of the 1st protruding item | line 21 and the 2nd protruding item | line 22 in the building board 1 will not be specifically limited. Such a building board 1 can be manufactured by carrying out curing hardening after press-molding a cement-type molding material using a predetermined metal mold | die.

  If it is said building board 1, damage to the uneven | corrugated pattern 7 on the surface can be suppressed at the time of packing etc. as follows. When packing the building board 1, as shown in FIG. 4 (a) (b), the surface in which the uneven | corrugated pattern 7 was formed is piled up by making 2 sheets into 1 set. At this time, the top and bottom of the two building boards 1 and 1 are reversed and overlapped. The concavo-convex pattern 7 formed on the surfaces of the two building boards 1 and 1 is the same, but both are located at a location where the ridge line 4 of the first ridge 21 is asymmetric with respect to the straight line 3. ing. Therefore, as shown to Fig.5 (a), the ridgelines 4 and 4 of the 1st protruding item | line 21,21 of the opposing building board 1,1 become difficult to contact, and the corner | angular part of each 1st protruding item | line 21 is hard to be missing. can do. If the ridgeline 4 of the first ridge 21 is located symmetrically with respect to the straight line 3, the first ridge is obtained when the building board 1 is inverted up and down around the straight line 3. 21 ridge lines 4 overlap each other. This means that when the building board 1 is packed as described above, the ridgelines 4 and 4 of the first ridges 21 and 21 of the opposing building board 1 and 1 are likely to come into contact with each other. In this case, the first protrusions 21 and 21 are rubbed with each other, and the corners of both are likely to be chipped.

  Moreover, in the building board 1, the 2nd protruding item | line 22 may be located in the location which becomes asymmetric with respect to said straight line 3, and may be located in the location which becomes symmetrical. As shown in FIG. 5B, even if the first ridges 21 and the second ridges 22 face each other, the ridge line 4 of the first ridges 21 only contacts the flat surface 212 of the second ridges 22. Since there is no catch, the corners of the first ridges 21 can be made difficult to chip. Further, as shown in FIG. 5C, even if the second ridges 22 face each other, only the flat surfaces 212 of these both come into contact with each other, and there is no catch. It can be made difficult to chip. In this way, damage to the concavo-convex pattern 7 on the surface of the building board 1 can be suppressed.

  Preferably, in each building board 1, with respect to the straight line 3, the ridge line 4 of the first ridge 21 is located at a location deviating from within a range of about ± 1.5 mm above and below the symmetrical location. . Thereby, even if the building board 1 packed as described above is displaced up and down by about ± 1.5 mm, the ridgelines 4 and 4 of the first ridges 21 and 21 of the opposing building board 1 and 1 are further in contact with each other. It becomes difficult.

  Moreover, it is preferable that the height of the second ridge 22 is formed higher than the height of the first ridge 21. Thereby, the 1st protruding item | line 21 becomes further difficult to contact the 1st protruding item | line 21 of the building board 1 which opposes.

  In addition, although the uneven | corrugated pattern 7 is formed in the surface of the building board 1, since the back surface is usually flat like Fig.4 (a), two sets of building boards 1 are piled up and packaged. And even if it transports in this state, damage to the uneven pattern 7 of each building board 1 is suppressed.
