[Problems to be solved by the invention]
Homogeneous members are manufactured from small pieces randomly cut from building boards having various uneven shapes, and a substantially central portion on the back surface is cut into a V shape and bonded. At this time, since the left and right design surfaces of the homogeneous members are randomly cut from the building board, there are many cases in which the shapes are different from each other. Therefore, when comparing the left and right designs of the completed homogeneous member, both surface designs have different block arrangements and there is no continuity of the design on the left and right, and even if the end surface of the homogeneous member forms a chamfer There is a problem that the right and left designs of the homogeneous members become uncomfortable because the convex block shapes of these portions do not match. Furthermore, when the joint portion exists at the end portion of the small piece cut and collected from the building board, a chamfered portion cannot be produced in the portion, so that the left and right designs of the homogeneous members are more uncomfortable.
In addition, if the positions where the small pieces are cut from the building board are selected too much in order to make the left and right design surfaces the same, the design surfaces will match, but many unnecessary edge portions will occur and the yield will deteriorate. There is a problem that the number of homogeneous members made from one building board is reduced.
[0005]
[Means for Solving the Problems]
As a means for solving the above-mentioned conventional problems, the present invention has a block-like pattern in which a plurality of convex blocks 3 partitioned by vertical and horizontal joint grooves 2 are arranged vertically and horizontally, and the arrangement of the horizontal joint grooves is the end 4 of the building board. It is a building board 1 which has the joint groove 21 which penetrates each other, Comprising: The chamfering part provided in one edge part 4 of the small piece 20 taken out from the process line AA for creating a homogeneous member from the said building board 1 And a convex block is arranged so that at least a pair of the chamfered portion provided at the other end of the small piece 20 has the same shape, and is taken out from the processing line AA for creating a homogeneous member from the building board 1. Provided a building board characterized in that a V-shaped cutting part is provided at the substantially central part of the back surface of the small piece, and convex blocks are arranged so as not to have joint grooves other than the part to be cut off To do.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to one embodiment shown in FIGS. In the present embodiment, a plurality of convex blocks 3 are partitioned on the surface of the building board 1 by vertical and horizontal joint grooves 2 and are arranged vertically and horizontally. At this time, the horizontal joint groove 21 is disposed so as to penetrate the building board 1.
The convex block 3 attached to the building board 1 has a substantially rectangular shape having an inclined surface portion and an upper surface portion, and the inclined surface portion and the surface portion may be provided with an uneven pattern as desired.
In the case of the present embodiment, a so-called horse joint is arranged, and in the convex block 3, the horizontal joint 21 is linearly continuous over the entire width of the building board 1, and the vertical joint is also provided. Are staggered at each stage so that their positions do not overlap. Moreover, the joint groove which divides the convex block has a flat shape.
[0013]
The building board 1 is made of a wood cement board which is a cement board mixed with wood reinforcing materials such as wood chips, wood powder, wood pulp, wood fiber bundles, wood wool, etc., and the convex block pattern is embossed before curing. Is formed on the surface of the building board. Here, the size of one piece of the building board is, for example, about 45 cm in width and about 3 m in length.
[0014]
A cross-sectional shape representing the convex block and the joint groove is shown in FIG. In the case of this example, the arrangement of the convex blocks in the horizontal direction is two types: a convex block of the same length divided by one joint groove, and two types of convex blocks divided by two joint grooves. The cross section in the former arrangement is shown as a CC cross section, and the cross section in the latter arrangement is a DD cross section.
Each cross-section is arranged with a slope 10 rising from the end 4 of the building board at a predetermined angle, a top face 5 of the convex block, and a joint groove 6 sandwiched between the slopes 10, and on the opposite side of the building board. A convex block is arranged at the end so as to form a similar slope portion 10. In this case, the predetermined angle of the slope is 60 °.
[0015]
The homogeneous member used for the corner portion of the outer wall cuts out the small piece 20 from the building board, cuts the substantially central portion of the back surface of the small piece 20 diagonally so as to be V-shaped, and applies an adhesive to the above-mentioned cutting portion. A homogeneous member bent in a letter shape is completed.
In this embodiment, the AA line shown in FIG. 1 and FIG. 2 indicates a cutting position for cutting out the small piece 20 having a predetermined size from the building board 1. And the line | wire shown by BB is a position cut by V shape. That is, the position BB, which is substantially the center of the back surface of the small piece 20 cut by the AA line, is cut by a cut saw that is parallel to the AA line and is inclined at an angle of 45 °. By this cutting position B-B, the substantially central portion of the back surface is cut off. The processing position B-B may be translated in a timely manner depending on the width dimension of the homogeneous member, and may be exactly V-shaped.
[0016]
In the case of the present embodiment, the building board is cut from the building board 1 at the processing position AA, and the two small pieces 20 are taken out. Here, as shown in FIG. 4, the cutting position of AA in the convex block arrangement such as the CC cross section desirably includes a boundary portion 7 between the joint groove and the slope portion of the convex block.
In the case of the convex block arrangement of the CC cross section, in the case of the convex block arrangement of the DD cross section, the slope 11 of the convex block remains at the end of the small piece 20 cut along the line AA. A U-shaped cross section is formed.
That is, if the building board is cut at the processing position A-A, the portion cut at the boundary portion 7 between the joint groove and the sloped portion of the convex block is such that one corner of the U-shaped cross section is chamfered in advance. On the other hand, the section cut at the upper surface of the convex block becomes a U-shaped cross section, and these cross sections are alternately arranged in the longitudinal direction of the small pieces 20.
[0017]
In the CC cross section shown in FIG. 3, the slope portion 10 of the end portion 4 of the building board 1 and the slope portion 11 of the end portion 41 cut by the AA cross section are arranged in a convex block so as to have the same shape. These have at least a pair. In the C-C cross section, the slope part of the embossed pattern pre-configured in the building board is used as it is, and the embossed pattern is designed so that the slope part of the convex block corresponding to the end position of the small piece has the same shape. ing. Therefore, at least a pair of the left and right chamfered portions of the homogeneous member processed and formed from the small pieces have the same shape, and the left and right convex blocks in the homogeneous member do not feel uncomfortable. Further, it is not necessary to newly cut the chamfered portion, and it is not necessary to paint the cut portion, thereby simplifying the process.
[0018]
In the DD cross section, the corner portion 9 of the U-shaped cross section is likely to be chipped, and is also inconvenient in design, so the corner portion 9 is cut to form the chamfered portion 12.
Thus, the chamfered portion 12 provided from the U-shaped cross section has the same shape as the sloped portion 10 of the convex block provided in advance at the other end of the small piece, and at least one pair has the same shape. Yes. That is, the slope portion 10 and the chamfered portion 12 of the convex block provided in advance by embossing have the same shape and constitute the left and right chamfered portions of the homogeneous member.
As described above, the building board according to the present invention has a projecting arrangement of convex blocks in consideration of avoiding a sense of incongruity between left and right designs of homogeneous members.
[0019]
Moreover, in the case of this example, the convex block made into the joint pattern is arrange | positioned, and CC cross section and DD cross section are arrange | positioned alternately in the vertical direction of a building board. In the convex block of the end portion 4 shown in FIG. 1, in other words, the end portion 4 of the small piece 20 on the side not cut by A-A, every other inclined surface portion 10 having the same shape is formed in the vertical direction. Convex blocks having the same chamfered shape are alternately arranged at the end 8 of the small piece 20 on the side cut by AA.
Therefore, the chamfering which cut the corner | angular part 9 of the convex block whose slope part 10 in a CC cross section and the slope part 11 on the opposite side have the same shape in DD section, and DD section. Since every other convex block having the same shape as the portion 12 is arranged, the discomfort of the right and left designs of the homogeneous members is further eliminated.
[0020]
As shown in FIG. 3, the points of caution when cutting the corner portion 9 to create a chamfered portion include the intersection between the sloped portion 10 of the convex block and the convex block surface 5, and the chamfered portion 12 and the convex block surface 5. The heights of the convex blocks H1 and H2 at the intersections must be the same. It is not necessary for all the convex block upper surface portions 5 to have the same height, but the heights of the convex blocks at the positions of the inclined surface portion 10 and the chamfered portion 12 need to be the same. This also applies to the convex block arrangement when the corner is not formed, and the heights of H1 and H2 when the convex block is embossed in advance are made to coincide with each other.
The above is an important element to make the shape of the chamfered portion the same, and the building board has a convex block shape in which the heights of H1 and H2 match in the chamfered portion, and the convex block is arranged as described above. ing.
[0021]
Moreover, as shown in FIG. 2, it is preferable that the arrangement | positioning of a convex block is made not to provide the joint groove | channel except the part cut off by diagonally 45 degree cut position BB. In this case, the convex block when the homogeneous member is formed has no joint groove in the width direction, and the left and right designs are continuously formed through the apex of the homogeneous member so that it appears as one convex block. Become. That is, it can arrange | position so that one piece of the convex block bent at right angle may exist like one piece of the convex block in the building board 1. FIG. This further improves the sense of unity between the homogeneous member itself or the homogeneous member and the building board.
[0022]
【The invention's effect】
In the present invention, the building blocks are provided with the convex blocks so that the ends of the small pieces processed when creating the homogeneous members have the same shape. The ends are the same design. In addition, the design of the building board is not only applied to the outer wall surface, but also considers the left and right chamfered portions of the homogeneous member to be applied to the corner portion, thereby creating a sense of unity without causing a sense of incongruity.
In addition, since the positions corresponding to both ends of the small piece are configured in advance so as to be the same convex block slope portion, it is not necessary to cut the chamfered portion when forming a homogeneous member, and further to the cutting portion The process is simplified without the need for new painting. In addition, since it is a construction board that is constructed on the flat part of the outer wall as a construction board, the construction of the slope part that forms the arrangement of chamfered blocks and the chamfered part on the premise of forming a homogeneous member, The processing yield of homogeneous members is good without impairing the design of the entire outer wall.
Furthermore, when no joint groove is provided except for the V-shaped processed portion, there is no joint groove in the width direction of the homogeneous member. One block is bent at a right angle, and the sense of unity is further improved.
