  First, the process for forming the plate-like end material will be described. First, as shown in FIG. 7A and FIG. 9, for example, when a square material S such as a column or a beam constituting a frame structure of a wooden building is made from a raw wood 18, the outer periphery of the raw wood 18 is cut along parallel lines. After cutting in the longitudinal direction along C1 and C2 to form two parallel surfaces, the square material S is formed by cutting in the longitudinal direction along parallel cutting lines C3 and C4 perpendicular to these two surfaces. . Here, as shown in FIG. 7B, the four end members H generated by the formation of the square member S are referred to as a tree back HR on the side of the annual ring N cut and a tree surface HF on the outside.

  Further, as shown in FIG. 8, square bars S1 or S2 corresponding to the outer shapes of the logs 18a and 18b can be cut out from the large and small logs 18a and 18b, respectively. Is formed.

  Furthermore, as shown in FIGS. 10A to 10C, among the four end members H generated by the formation of the square member S, the thick end member H is cut in parallel with the back HR plane. By cutting in the longitudinal direction along the line C5, it can be used as a plate material H ′ for assembling, and the end material H ″ generated thereby can be used as a heat insulating material.

  Next, an end material processing step, which is a first step that is a preparatory work for manufacturing a heat insulating material, will be described with reference to FIG.

  In the first step ST1, a square bar S that becomes a core material of a pillar or a beam is manufactured by cutting the outer periphery of the raw wood 18 in the longitudinal direction along parallel cutting lines C1 to C4 at a sawmill, and the next step In ST2, end materials H of various sizes generated at the time of manufacturing the square member S are collected.

  In process ST3, the collected various scraps H are peeled to make grass weeds, and in step ST4, the scraps H are naturally dried for about two weeks to become usable scraps H. Is completed (step ST5).

  Next, the manufacturing process of the heat insulating material using the lumber mill ends will be sequentially described with reference to FIGS.

  First, as shown in FIGS. 12A and 12B, for example, a roller conveyor 20 is prepared as a transport table having a function of a work table for assembling the end material H, and this is installed on the work table T. The roller conveyor 20 has frames 22a and 22b having a predetermined length (a length of at least 6 lengths) serving as a pair of parallel guides on both sides, and a plurality of frames 22a and 22b are disposed below the frames 22a and 22b. A roller R is rotatably supported at a predetermined interval.

  The width L2 of the outer sides of both frames 22a and 22b of the roller conveyor 20 is set to a prescribed width L2 (for example, 454 mm) shown in FIG. 14, and both frames 22a and 22b are disposed in front of the conveyance path of the roller conveyor 20. A horizontally long cutting device 24 is installed so as to be orthogonal to the conveyance path from the inner gap, and for example, a scale (not shown) based on the cutting device 24 is attached to the upper surface of one of the frames 22a.

  Therefore, a pair of linear splint ends HS are disposed on the plurality of rollers R along the inner sides of both frames 22a and 22b of the roller conveyor 20, and various lengths prepared in advance between the splint end members HS. The end material H is flat so that there is no gap over a predetermined length on the roller conveyor 20 (length of 6 or more lengths) so that the tree back HR surface is supported by the upper surfaces of the plurality of rollers R. The first-stage end material layers HP1 are formed by arranging them in a line.

  Next, as shown in FIGS. 13 (a) and 13 (b), a plurality of downwardly directed upper surfaces of the wood surface HF between adjacent end materials H constituting the first-stage end material layer HP1 on the roller R of the roller conveyor 20 are provided. A second-stage end material layer HP2 is formed by overlapping and arranging both sides of the wood surface HF in a plane.

  In this way, as shown in FIG. 14 in which the roller conveyor is omitted, the rectangular heat insulating material 4 is temporarily assembled together with the two splints HS while being set to the specified width L2. In this process, the lengths of both ends of the end material H constituting the first and second end material layers of the heat insulating material 4 are still uneven. In the final process, as described later, a specified length L1 (for example, 6 scales = 1). , 818 mm).

The first and second end material layers HP1 and HP2 can be fixed at the same time by this nail driving. However, both sides of the adjacent upper and lower wood surfaces HF which are alternately stacked on each other are sequentially arranged in the width direction by nail driving. By joining, the first and second step end material layers HP1 and HP2 can be integrally formed together with both splint wood end materials HS. Then, on the upper surface of the second-stage end material layer HP2, a single end-material layer serving as a decorative board (not shown) is translated in a horizontal direction by a predetermined amount via the kraft paper P and is nailed in a state where it is superimposed on the uppermost stage. Are joined together.

  When the heat insulating material 4 integrally formed in this way is transferred to the cutting device 24 by the roller conveyor 20, the tip thereof is cut and aligned in the direction perpendicular to the conveyance path at the cutting line C6 as shown in FIG. Further, the cutting device 24 is moved to the position of 6 scales on the scale, and the rear end is cut along the cutting line C7 to form the rectangular heat insulating material 4.

As a single end material layer HP constituting a part of the heat insulating material 4, a plurality of end materials H are arranged in a line along the splint end material HS, and a prescribed external dimension [L1 (1,818 mm) × L2 (454 mm). 4) single end material layers HP formed in a planar rectangular shape are prepared.

  First, the kraft paper P (see FIG. 2) is interposed between the single end material layer H4 placed on the uppermost stage with the end material layers HP1 to HP3 superimposed in three stages and the lower end material layer HP3. Then, the uppermost end material layer HP4 is translated in the lateral direction by a predetermined amount (for example, L3 = 30 mm) to form a step M1 on the upper surface of the one-side splint material HS of the lower end material layer HP3 and 3 Joining for joining the other side edge of the end material layer HP4 protruding a predetermined amount (30 mm) from the upper surface of the other end side splint end material HS of the step end material layer HP3 to the step M1 of the adjacent heat insulating material 4 Formed as a piece M2.

  Therefore, when this heat insulating material 4 is used for a roof, the heat insulating material 4 is placed and fixed on the upper surfaces of a plurality of rafters 5 arranged obliquely side by side as shown in FIGS. The joining piece M2 of the heat insulating material 4 is supported on the upper surface of the step M1 on one side of the heat insulating material 4 adjacent to the upper and lower sides and connected by nailing or the like. In this way, by connecting the adjacent heat insulating materials 4 sequentially, it is possible to construct a flush partition portion without a gap on the upper surface of the rafter 5.

  Next, when using this heat insulating material 4 for the outer wall surface, as shown in FIG. 3, the heat insulating material 4 is fixed to the front surface between the columns 2 including the vertical columns 2 a so as to be perpendicular to each other, as shown in FIG. The joining piece M2 of the heat insulating material 4 is supported on the upper surface of the step M1 on one side of the heat insulating material 4 adjacent to the upper and lower sides and connected by nailing or the like. In this way, by connecting the adjacent heat insulating materials 4 sequentially, it is possible to construct a uniform partition portion without a gap on the front surface of the pillar 2 or the inter-column 2a.

  Furthermore, when this heat insulating material 4 is used on the floor surface, as shown in FIG. 4, the heat insulating material 4 is fixed so that the longitudinal sides are orthogonal to the upper surface between the plurality of joists 15 supported by crossing the upper surface. Then, the joining piece M2 of the heat insulating material 4 is supported on the upper surface of the step M1 on one side of the heat insulating material 4 adjacent to the left and right and connected by nailing or the like. In this way, by connecting the adjacent heat insulating materials 4 sequentially, a flush partition part without a gap on the upper surface of the joist 15 can be constructed.

  Therefore, by adopting the construction method using the heat insulating material of the present invention manufactured using the above-mentioned lumber mill ends, the longitudinal side is orthogonal to the upper surface of the rafter 5, the joist 15 or the pillar 2 or the like. When the panel-like heat insulating material 4 is attached, the workability can be improved by using the step M1 and the joining piece M2 of the adjacent heat insulating materials 4, and the flat partition without gaps.
