  The present invention relates to a structural material having a rectangular cross section and having a phase cutout at one end.

  As this type of structural material, a building material unit disclosed in Patent Document 1 below is known. This building material unit is a building material unit used when building a building structure, and is configured by superimposing three plates. In this case, in this building material unit, both end portions of the outer two plate members of the respective plate members are aligned, and the central plate member is overlapped in the length direction with respect to the outer two plate members. By combining, at one end, an uneven portion is formed in which the central plate is retracted from the two outer plates, and at the other end, an uneven portion is formed where the central plate protrudes from the two outer plates. ing. This concavo-convex part functions as a joint part, and after inserting and fitting the concavo-convex part of one building material unit into the concavo-convex part of another building material unit, the nail is struck into the fitting part (joint part) and joined.

Let

  Specifically, first, as shown in FIG. 6, the structural material 1x is arranged with the phase missing portion 6x facing upward, and the structural material 1y with the phase missing portion 6y facing downward is placed above the structural material 1x. To be located. Next, as shown in FIG. 7, each one end of each first protrusion P1 and each fifth protrusion P5 in the phase notch 6y, and each third protrusion P3 and each fourth protrusion in the phase notch 6x. The structural material 1y is moved downward to a position where each one end portion of P4 contacts (the structural material 1y is brought close to the structural material 1x).

  Subsequently, as shown in FIG. 8, each one end of the first protrusion P1 and the second protrusion P2 in the phase notch 6x abuts on the first phase notch surface 61 of the phase notch 6y, and the phase notch 6y. The structural material 1y is moved in the lateral direction (to the right in the figure) to a position where one end of each of the first protrusion P1 and the second protrusion P2 contacts the first phase notch surface 61 of the phase notch 6x ( The structural material 1y is brought close to the structural material 1x).

  Next, as shown in FIG. 9, the structural material 1y is moved downward. At this time, as shown in FIG. 10, the second projecting portion P2 of the phase missing portion 6y is fitted into the gap G1 (see FIG. 4) of the phase missing portion 6x, and the third projecting portion P3 in the phase missing portion 6x and The fifth protrusion P5 of the phase missing portion 6y is fitted into the gap G3 between the fourth protrusion P4. Further, the gap G4 (see FIGS. 2 and 4) between the adjacent third protrusions P3 and the gap G5 (see FIGS. 2 and 4) between the adjacent fourth protrusions P4 in the phase notch portion 6x. The sixth protrusion P6 of the notch 6y is fitted, and the gap G6 (sixth gap) between the first phase notch surface 61 and the third protrusion P3 in the phase notch 6x is the second of the phase notch 6y. The extension part from the front end surface 5 in 1 protrusion part P1 fits. Further, the respective parts are fitted in a relationship in which the respective parts of the phase missing part 6x and the respective parts of the phase missing part 6y are reversed.

(M) fourth protrusions P4 are provided, and three (m) fifth protrusions P5 and two (k) sixth protrusions P6 are provided on the distal end surface 5 of the structural material 1. By simply engaging the phase notches 6 of the two structural materials 1 with each other without nailing, the direction perpendicular to the length direction D4 of the connected structural materials 1 (second direction D2 and The relative movement of each structural material 1 in the third direction D3) can be reliably restricted. For this reason, according to this structural material 1, even if an external force acts in a direction orthogonal to the length direction of the structural material 1, the engagement state between the phase notches 6 is reliably maintained against the external force. Therefore, sufficient strength of a structure (such as a building body) configured using the structural material 1 can be ensured. Moreover, according to this structural material 1, since it is not necessary to nail, connection efficiency can fully be improved.

  Moreover, according to this structural material 1, by forming the plurality of first plate-like members 11 and second plate-like members 12 so as to overlap each other, it is possible to form the protrusions P1 to P6 on each plate-like member. Further, it is possible to easily create the phased portion 6 having a complicated shape in which a large number of protrusions P1 to P6 are arranged in a complicated state.

  Further, according to the structural material 1, the first protrusion is formed such that the gap G7 is generated along the first direction D1 between the first protrusion P1 and the second protrusion P2 in a state where the side surface 4b is viewed in plan. By providing the P1 and the second projecting portion P2, the insertion hole H can be formed by the gap G7 when the phase notches 6 of the two structural materials 1 are engaged with each other. By inserting a pile into H, the movement (separation) of the structural materials 1 in the length direction can be reliably regulated and the structural materials 1 can be firmly connected.

  Note that the structural material is not limited to the above-described configuration. For example, instead of the phase notch portion 6 described above, a structural material 1A provided with a phase notch portion 6A shown in FIG. 11 may be employed. In addition, in the following description, about the same component as the above-mentioned structural material 1, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

  In the phase cutout portion 6A of the structural material 1A, as shown in FIG. 11, two (k) seventh protrusions P7 are provided on the second phase cutout surface 62. In this case, each of the seventh protrusions P7 passes through each intersection point I3 between the first straight line S1 and the second phased surface 62, and the sixth protrusion P7 on the sixth straight line S6 that is a straight line along the third direction D3. They are arranged at positions separated from the one-phase notch surface 61 by a length L5 (corresponding to the fifth length: 70 mm as an example). Each of the seventh protrusions P7 has the same width as the gap G4 (the gap between adjacent third protrusions P3) and the gap G5 (the gap between adjacent fourth protrusions P4), and the second width. They are formed so as to protrude from the phased surface 62 by a length L2 (see FIG. 12) along the first direction D1.

When the phase notches 6A of the structural material 1A are engaged with each other, in addition to the fitting of the respective portions in the phase notch 6 described above, the seventh protrusion P7 and the notch C are fitted, so that the structural material Since the relative movement of each structural material 1A in the direction orthogonal to the length direction of 1A can be more reliably regulated, the strength of the structure formed using the structural material 1A can be further increased.

For example, when n is defined as 3 as the lowest value, m can be defined as 2 and k can be defined as 1. When n is defined as 7, m can be defined as 4, and k can be defined as 3. In this case, the number of the first plate-like members 11 and the second plate-like members 12 and 12A constituting the structural materials 1 and 1A can also be changed according to the number of protrusions.

Can be changed. In this case, the first plate-like member 11 and the second plate-like members 12, 12A may have different thicknesses. Moreover, you may form the some 1st plate-shaped member 11 in mutually different thickness, and when the 2nd plate-shaped members 12 and 12A exist in multiple numbers, each 2nd plate-shaped member 12 and 12A differs in thickness mutually. You may form in.

  Moreover, it replaces with the structure which piled up several plate-shaped member 11,12,12A, and comprised with a single material (for example, metal, resin (foamed resin and non-foamed resin), rubber, concrete, stone, etc.). It is also possible to adopt the structured material. In this case, in the configuration using a single material, one end portion is cut to form the phase missing portions 6 and 6A, or a mold having a shape that represents the phase missing portions 6 and 6A is filled with resin or concrete.
