The corrugated nail 14 is shorter than the thickness of the end material plate 8 (building material thickness t1). The nail 15 is struck between the center portions in the thickness direction of the end material plate 8.

  Further, as shown in FIG. 9, an adhesive 17 can be used for the joining means 10. The adhesion with the adhesive 17 is performed by pre-treating the skin portions on both side surfaces, and then applying the adhesive 17 to the side surface of the end plate 8 as shown in FIG. The parts are brought into close contact with each other, or as shown in FIG. 9B, a gap between the side surface parts of the end material plate 8 is filled with the adhesive 17.

  Further, as shown in FIG. 7, an end material plate combination building material 21 is configured by cutting the wooden end of the end material plate combination face material 11 into a building material shape. Reference numeral 22 indicates an example of a tree edge cut line in a rectangular shape.

  Auxiliary building material 25 is bonded to one side or both sides of the end material plate combination building material 21 thus formed to form a multilayer material 26. For bonding the auxiliary building material 25, for example, an adhesive or a nail is used.

Note that FIG. 15 shows an example of single-sided attachment, but double-sided attachment is also possible. In this case, a sheet material 32 is used as the semi-deformed material 31. As the sheet material 32, a waterproof sheet-based material, a moisture-permeable waterproof sheet, and other materials can be used. Examples of the waterproof sheet material 32 include a vinyl chloride sheet, a poly film, a thin steel plate, asphalt waterproof paper, and others. Examples of moisture permeable waterproof sheets include Tyvex. Examples of other sheets include paper and cloth.

  Next, the operation of this embodiment will be described.

  According to this embodiment, the skin surface of the lumber edge material 4 which is the remaining material around the skin after cutting off from the raw wood 1 is cut into a building material board thickness to obtain a substantially trapezoidal end surface portion 6 and a substantially trapezoidal shape. An end material plate 8 having a plate surface portion 7 is provided, and a plurality of end material plates 8 are combined by alternately inverting and arranging trapezoidal end surface portions 6 and alternately inverting and arranging trapezoidal plate surface portions 7. The side portions of the adjacent end material plates 8 are joined by the joining means 10 to form the end material plate combined face material 11, and the end of the end material plate combined face material 11 is cut into a building material shape. Since the union building material 21 is configured, it is possible to effectively utilize the lumber edge material 4 that has been discarded so far as the building material.

  At this time, by forming the multi-layer material 26 by laminating the auxiliary building material 25 on one side or both sides of the end material plate combination building material 21, various functions are given to the end material plate combination building material 21, and the purpose and use Depending on the situation, it can be used for various purposes.

  For example, by bonding the auxiliary building material 25, the strength can be increased as compared with the case of the end material plate combined building material 21 alone. When the auxiliary building material 25 is bonded to one side of the end material plate combination building material 21, the end material plate 8 is mainly responsible for the longitudinal strength of the end material plate 8. The strength of the direction is mainly handled by the auxiliary building material 25. Further, when the auxiliary building material 25 is bonded to both surfaces of the end material plate combination building material 21, the auxiliary building material 25 has both the strength in the longitudinal direction of the end material plate 8 and the strength in the short direction of the end material plate 8. Since it will be in charge, higher strength can be obtained.

  And the intensity | strength can be provided by setting the auxiliary | assistant building material 25 bonded to the end material board combination building material 21 to the fixed form material 27. FIG.

  In particular, the strength in the surface direction can be increased by using the shaped material 27 as the face material 28 that covers the entire surface of the end material plate combined building material 21.

  In this way, the multi-layer material 26 of the end material plate combined building material 21 in which the face material 28 is bonded as the auxiliary building material 25 is, for example, a floor base plate, an inner wall base plate, a ceiling base plate, a door, furniture, etc. It can be used for applications that require a flat surface on the entire surface. In this case, as the face material 28, a flat material such as a plywood board, a gypsum board, and a flat steel sheet is used. Further, for example, it can also be used for applications where ventilation from the surface is expected, such as a roof base plate (prevention of dew condensation on the back of a hut) and an outer wall base plate (prevention of dew condensation in the wall). In this case, a lath metal mesh, an expanded metal, a perforated steel plate, or the like is used for the face material 28.

  Or, the strength in the intersecting direction can be increased by making the shaped material 27 cross the end material plate 8 to be the horizontal plate material 29 over the entire width of the end material plate combined building material 21. However, although the strength cannot be expected due to the longitudinal direction of the end material plate 8 being divided, the end material plates 8 can be integrated with each other, so the gap between the end material plates 8 is used as a ventilation slit or the like. It is also possible.

  As described above, the multi-layered material 26 of the end material plate combined building material 21 in which the horizontal plate material 29 is bonded as the auxiliary building material 25 includes, for example, a roof base plate (prevention of dew condensation on the back of the hut), an outer wall base plate (prevention of dew condensation in the wall) ), Can also be used for applications that expect ventilation from the surface, such as snowboard (drainage). Further, by arranging the horizontal plate material 29 on the back surface of the auxiliary building material 25 in accordance with the pitch of the floor joists and the ceiling edge, it can be used for applications that do not hinder even if projections are generated on the surface. In this case, the surface side (floor surface or ceiling surface) can be made flat.

  Furthermore, by using the other end material plate combination building material 21 over the entire surface of the end material plate combination building material 21 as the fixed shape material 27, the end material plate combination building material 21 alone can provide strength. In addition, as shown in FIG. 13, when wood ends are aligned and pasted together, a watermark and a blind joint are formed between adjacent building materials. In addition, as shown in FIG. 14, when pasted together with the ends of the trees being different, the adjacent building materials are connected to each other with a phase gap or a joint.

  Thus, as the auxiliary building material 25, the multi-layer material 26 in which the end material plate combination building material 21 and the end material plate combination building material 21 are bonded to each other in a different manner includes, for example, a floor base plate, an outer wall base plate, a roof bottom It can be used for applications that require a substantially flat surface on the entire surface, such as a base plate (an application in which the gap between the end plate 8 is not penetrating the end layer).

  Moreover, the auxiliary | assistant building material 25 stuck on the end material board combination building material 21 can provide the characteristic which is easy to deform | transform by making it the semi-definite shape material 31. FIG. For example, when the sheet material 32 is bonded on one side, it can be formed into a scroll. In addition, the sheet material 32 can be made into a stacking allowance such as a waterproofing allowance by making it an extra large size.

  As described above, the multi-layer material 26 of the end material plate combination building material 21 in which the semi-shaped material 31 such as the sheet material 32 is bonded as the auxiliary building material 25 is attached to, for example, a curved surface or a half-folded rafter as a base plate. Thus, it can be used for applications such as a base constituting a non-flat surface. Moreover, it can use for the use which comprises a waterproof surface by sticking a waterproof sheet beforehand as a roof base plate and a wall base plate. It should be noted that an extra sheet material 32 is superimposed on the connecting portion.
