Abstract

PROBLEM TO BE SOLVED: To provide a low strain high strength product of a specific width and a specific length by a method wherein oblique board members in which irregular width jointed board materials are inclined by a specific angle on the same surface, and a plurality of longitudinal side edges are bonded by suprimposing vertically by crossing fibrous angles. SOLUTION: A building board material is composed of a laminate of two oblique board members 10. Each oblique board member 10 is manufactured by a method wherein a plurality of width jointed board materials having various widths are arranged adjacently on the same plane by arranging fibrous directions properly, and longitudinal side edges of respective width jointed boards are bonded to each other with an adhesive. However, the width jointed board 11 forming a front plate is obliquely arranged by forming an angle of 20-23 deg. concerning a longitudinal center line of the oblique board member 10. The width jointed board 11 being a rear plate is arranged obliquely to an opposed direction of the oblique board member 10 being the front plate. Those oblique members 10 are superimposed vertically by two layers, and bonded with the adhesive to manufacture the board material. Therefore, the board material which has a 3×6 product size, no strain, and large strength, can be obtained.

A plurality of strips are arranged on the same plane and the longitudinal side edges are adhered to each other to form a plate having a desired width. In a building strip by a stripping method, a strip strip having a non-uniform width is desired. The thickness is ½ of the plate thickness, and in the state where a plurality of the plates are arranged diagonally at a constant angle in the range of 20 to 23 ° on the same plane, the longitudinal side edges are adhered to each other to obtain a desired plate thickness. A swash plate member having a thickness of ½ is formed, and the swash plate members are laminated in two layers on the upper and lower sides so that the width strips of the swash plate members intersect each other, and are integrally bonded to both side edges and upper and lower ends.

As described above, since the width strips of the upper and lower two-layer swash plate members intersect, the strength is high, and even if the product width is 914 mm, the strength does not decrease and the strain does not increase. The length of the raw wood is usually 4 m because it is based on what is called Saburoku, and the width of the width material is cut out from a piece cut into 2 m. Therefore, the width of the width material is diagonally arranged. Although the length is shorter than the length of the raw wood, it is desired by setting the crossing angle of the upper and lower width strips to be 40 to 46 ° (that is, the inclination angle of one swash plate member is 20 to 23 °). A rectangular building board with a length of 1829 mm can be obtained.

2 mm. The building board itself is made up of a laminate of two swash plate members 10, as shown in FIG. Each swash plate member 10 is composed of a plurality of width strip members 11. Each of the width strips 11 has a thickness t of 6 mm, a length of 2000 mm, and a width of 60 to 150 mm. In each swash plate member 10, a plurality of width strips 11 having such various widths are arranged adjacent to each other with their fiber directions aligned and arranged on one plane, and the side edges of the strips in the longitudinal direction are aligned with each other. It is made by bonding with an adhesive.
However, all of the width strips 11 in one swash plate member 10 forming the front plate are obliquely arranged so as to form an angle of 20 to 23 with respect to the longitudinal centerline of the swash plate member 10, and All of the width strips 11 of the other swash plate member 10, which is the same as the front panel, face in the direction opposite to the width strips 11 of the front plate, and the longitudinal centerline of the swash plate member 10 that serves as the back plate. Are obliquely arranged so as to form an angle of 20 to 23 °. The building board material is made by stacking these swash plate members 10 in two layers, and joining the overlapping surfaces of the swash plate members with an adhesive. Therefore, the width stripping material 11 in each swash plate member 10 of the building board material forms an included angle θ of 40 to 46 °.

てなされる。In the production, a scrap material obtained by removing a lumber and a plate material from a raw wood is used, but a width stripping material 11 having a thickness t which is ½ of a thickness T of a building board material to be produced, for example, 6 mm. Made from this waste material, as shown in Figure 3,
The obtained width strips 11 are arranged obliquely with their fiber directions aligned on one plane, and the side edges in the longitudinal direction of each strip 11 are temporarily joined with an adhesive to form the swash plate member 10. In addition, two width strips 11 are vertically stacked so that the fiber directions intersect with each other and the swash plate members are bonded together.

とができる。At this time, the width strips 11 obtained from the waste wood of the length of 2 m are simply arranged obliquely to form a plate having a desired width, and the width strips are compared with a plate in which the strips are arranged in a straight line. There is a possibility that the length becomes short and a plate material having a length of 1829 mm cannot be obtained. However, in the building board material according to the present invention, as described above, the width is 60 to 150 mm.
Since the width strips 11 made of 2 are arranged side by side at a constant angle in the range of 20 to 23 °, it is possible to obtain the swash plate member 10 having a length of 1829 mm from the strips of 2 m of raw wood. .

The relationship between the width d of the width strip 11 and the inclination angle α at which the distance between the start point a and the end point b of the diagonal line 1 is 1829 mm is as follows.

Are obliquely arranged and joined on one plane at an angle α related thereto to form a swash plate member, and the upper and lower end edges of each of the width strips 11 are cut along a straight line passing through diagonal points a and b. By cutting and cutting both side edges along the longitudinal direction for each width of 914 mm, a plate material 10 having a length of 1829 mm can be obtained by a width stripping material obtained from a log having a length of 2 m. In this case, the width dimension of each width strip 11 is 60 to 1.
In order to obtain a plate material having a length of 1829 mm, which is not uniform like 50 mm and has such a width strip material, there is a certain limitation on the inclination angle α, and the width strip material of various width dimensions is used. Considering that 11s are randomly arranged and joined,
It is necessary to set the inclination angle α in the range of 20 to 23 °.
