At least one end side of the building material unit has a joint portion to be a joint with another building material unit,
Provided is a building material unit in which the joint portion is an unevenness formed in the length direction, which is a combination of two or more stacked plate members.

  The building material unit of the present invention has a combination of two or three or more plate members, and when viewed from the side, unevenness is formed in the length direction on one end side or both end sides, and this unevenness becomes a joint portion. It is.

  When the building material unit of the present invention is composed of two plate members having the same length, when they are combined with being shifted in the length direction, one protrudes from both ends, and an unevenness is formed in which the other is retracted.

  When the building material unit of the present invention is composed of three plates of the same length, the two outer edges are aligned with each other, and when one of the inner sheets is shifted, the inner one is retracted to one end. A concave portion is formed, and a convex portion is formed on the other end side.

  When the building material unit of the present invention is composed of two sheets of the same length and one sheet material shorter than the other two sheets, the short sheet material is sandwiched between the two long sheets, and the three sheets When one end side of each is combined, a concave portion into which one of them is retracted is formed on the other end side. Conversely, when using a total of three sheets of two sheets of the same length and one sheet of longer sheet than the other two sheets, a building material unit having a protruding portion protruding from one of the sheets is obtained.

  The same applies to the case where the building material unit of the present invention is composed of four or more plates, and in the case of plates of the same length, they are staggered one by one or two at a time. In the case of plate materials of more than types, irregularities are formed on one end side or both end sides by alternately shifting them one by one or by two.

  In the building material unit of the present invention, for example, a concave portion of one building material unit and a convex portion of another building material unit are combined, and the combined portion is joined by a nail, a screw, a screw, a bolt, or the like, or an adhesive and a combination thereof.
