The heat insulating material is accommodated inside the frame body, and the plurality of crossbars are respectively accommodated in the plurality of concave grooves. The plates are fixed to both surfaces of the frame material by screws or the like, and the region inside the frame body is blocked by the plates.

[0004] Patent Document 3 discloses a technique of arranging a heat insulating panel in an internal space surrounded by columns, a base, and a beam. The heat insulating panel includes a frame material, a cross member, and a heat insulating material. The frame material is provided along the periphery of the internal space. The cross member is arranged inside the frame material. The heat insulating material is accommodated inside the frame material. The heat insulating material is shaved off by the thickness of the cross member at the site. In order to fit into the portion where the cross member is shaved off without a gap, it is necessary to make the width of the shaved-off portion equal to the width of the cross member. Further, if the shaved-off portion is displaced from the position of the cross member, the cross member will protrude from the portion where the cross member is shaved off, which will cause compression of the heat insulating material and further cause a decrease in the heat insulating performance of the heat insulating material.

[0009] According to claim 6, A method of using the marking tool (20 or 120) described in claim 1, A diagonal brace (10) is provided along the diagonal of a rectangular region (6) enclosed by two parallel columns (4 and 5) and parallel upper and lower horizontal members (2 and 3), and is fitted into the region enclosed by the web (22 or 122) and the first and second flanges (23 and 24, or 123 and 124). The insulating material (99) is placed against the web (22 or 122), and the first and second protrusions (31 and 32, or 131 and 132) are inserted into the insulating material (99) to mark the insulating material (99). Instructions for use will be provided.

[0010] According to claim 7, A method of using the marking tool (20 or 120) described in claim 1, The web (22 or 122) is divided between the first edge (22a or 122a) and the second edge (22b or 122b) along a line parallel or oblique to the first edge (22a or 122a), The divided parts of the web (22 or 122) are placed against the surface of the diagonal brace (10) provided along the diagonal of the rectangular region (6) enclosed by two parallel columns (4 and 5) and parallel upper and lower horizontal members (2 and 3), and the first and second flanges (23 and 24, or 123 and 124) are placed against both sides (11 and 12) of the diagonal brace (10), respectively.

Embodiments for Carrying Out the Invention

[0019] Hereinafter, embodiments will be described with reference to the drawings. The features and technical effects of the embodiments will be understood from the following detailed description and the drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. Since the drawings are provided for illustrative purposes only, the scope of the present invention is not limited to the illustrations in the drawings.

[0020] 〔First Embodiment〕 Figure 1 is a perspective view showing frame 1, which constitutes a part of a wooden building constructed using the traditional post-and-beam construction method.

[0021] Frame 1 constitutes the outer perimeter of the wooden building and also serves as the base for the exterior walls of that perimeter. The exterior walls may be the exterior walls of the first floor or higher floors of the wooden building. Frame 1 comprises lower horizontal members 2, upper horizontal members 3, and columns 4 and 5. Lower horizontal members 2 are installed horizontally. Lower horizontal members 2 are sills, beams, or girders. Lower horizontal members 2 may be beams or girders such as girder beams. Upper horizontal members 3 are installed above and parallel to upper horizontal members 2. Upper horizontal members 3 are beams or girders. Upper horizontal members 2 may be beams or girders such as roof beams or girder beams. Columns 4 and 5 are positioned with a gap between them on the left and right between lower horizontal members 2 and upper horizontal members 3. Columns 4 and 5 are erected vertically and joined to lower horizontal members 2 and upper horizontal members 3. In the example shown in Figure 1, columns 4 and 5 are standard columns. One or both of columns 4 and 5 may be continuous columns. Inside frame 1, a rectangular area 6 is formed, enclosed by horizontal members 2 and 3 and columns 4 and 5.

[0022] The rear surfaces of horizontal members 2 and 3 are flush with the rear surfaces of columns 4 and 5, and the front surfaces of horizontal members 2 and 3 are flush with the front surfaces of columns 4 and 5. Therefore, horizontal members 2 and 3 and columns 4 and 5 have thickness in the out-of-plane direction, and the thicknesses of these horizontal members 2 and 3 and columns 4 and 5 are equal to each other. The out-of-plane direction refers to the direction perpendicular to the rectangular plane defined by horizontal members 2 and 3 and columns 4 and 5. The out-of-plane direction is perpendicular to the rear and front surfaces of horizontal members 2 and 3 and columns 4 and 5.

[0023] Stud 9 is positioned parallel to columns 4 and 5 between columns 4 and 5. Stud 9 is erected vertically and joined to the lower horizontal member 2 and the upper horizontal member 3. The stud 9 has thickness in the out-of-plane direction, and the out-of-plane thickness of stud 9 is equal to the out-of-plane thickness of horizontal members 2 and 3 and columns 4 and 5. The rear surface of stud 9 is flush with the rear surfaces of horizontal members 2 and 3 and columns 4 and 5, and the front surface of stud 9 is flush with the front surfaces of horizontal members 2 and 3 and columns 4 and 5. Stud 9 divides the rectangular region 6 into two rectangular regions 7 and 8.

[0024] One end of the brace 10 is joined to the inner corner between the lower horizontal member 2 and the column 4, and the other end of the brace 10 is joined to the inner corner between the upper horizontal member 3 and the column 5. The brace 10 is provided along the diagonal of the rectangular region 6, spanning these inner corners. The brace 10 is a strip-shaped wooden flat brace. The brace 10 has thickness in the out-of-plane direction, and the out-of-plane thickness of the brace 10 is thinner than the out-of-plane thickness of the horizontal members 2, 3, columns 4, 5, and studs 9. The brace 10 has width in the direction perpendicular to the out-of-plane direction and the diagonal direction. At the intersection of the brace 10 and the studs 9, a notch is formed in the middle of the studs 9, and the middle part of the brace 10 fits into the notch. The rear surface of the brace 10 is flush with the rear surfaces of the horizontal members 2 and 3 and the columns 4 and 5, while there is a step between the front surface of the brace 10 and the front surfaces of the horizontal members 2 and 3 and the columns 4 and 5.

[0025] When constructing the exterior wall on the frame 1 as described above, a rectangular insulation board 99 made of, for example, rock wool, glass wool, or foamed resin (polystyrene foam, urethane foam, polyethylene foam, or phenolic foam) is placed within the rectangular area 7. If the insulation board 99 is simply pushed into the rectangular area 7 from the front to the back, the brace 10 will hit the insulation board 99, and the thickness of the brace 10 will partially crush the insulation board 99. This will lead to a decrease in the insulation performance of the insulation board 99. Therefore, before placing the insulation board 99 into the rectangular area 7, a recess is formed by partially cutting the insulation board 99. When placing the insulation board 99 into the rectangular area 7, the recess is aligned with the brace 10, and the brace 10 is placed into the recess. The same applies when placing the insulation board 99 into the rectangular area 8.

[0026] However, if the recess is formed in the insulation board 99 by visual estimation, there is a risk that the shape of the recess may not match the shape of the brace 10, or that the position of the recess may not match the position of the brace 10. Therefore, multiple marking tools 20 are used to mark the positions of the marks on the insulation board 99, aligning them with the positions of the sides 11 and 12 of the brace 10. The recess is formed by cutting the insulation board 99 along the lines connecting the marks. The marking tool 20 is also called a marking device.

[0027] The marking tool 20 is described in detail below. Figures 2 and 3 are perspective views of the marking tool 20. The marking tool 20 is manufactured by sheet metal processing. The marking tool 20 comprises a holder 21, marking projections 31, 32 and fastening projections 41, 42.

[0028] The holder 21 is formed in a groove shape (U-shape). Specifically, the holder 21 has a web 22 and flanges 23 and 24. The web 22 is formed in a flat shape. The flange 23 is bent so that it is perpendicular to the web 22 at the first edge 22a of the web 22. The flange 24 is bent so that it is perpendicular to the web 22 at the second edge 22b opposite to the first edge 22a of the web 22. The flanges 23 and 24 rise in the same direction and face each other. The distance between flanges 23 and 24 is equal to the width of the brace 10. A cut line 29 may be formed on the web 22. In the example shown in Figure 3, the cut line 29 is parallel to the edges 22a and 22b of the web 22. The cut line 29 may be oblique to the edges 22a and 22b of the web 22. The cutting line 29 is, for example, a groove such as a score section. The cutting line 29 does not necessarily have to be formed.

[0029] The marking projection 31 protrudes from the first edge 22a of the web 22 in the opposite direction to the rising direction of the flange 23. The marking projection 31 is a small triangular piece formed by cutting and bending. An opening 25 is formed in the web 22 at the base of the marking projection 31. The opening 25 is formed by cutting and bending the marking projection 31 from the web 22.

[0030] The marking projection 32 protrudes from the second edge 22b of the web 22 in the opposite direction to the rising direction of the flange 24. The marking projection 32 is a small triangular piece formed by cutting and bending. An opening 26 is formed in the web 22 at the base of the marking projection 32. The opening 26 is formed by cutting and bending the marking projection 32 from the web 22. The distance between the marking projection 31 and the marking projection 32 is equal to the width of the brace 10.

[0031] The fastening projections 41 and 42 protrude from the web 22 in the same direction as the rising direction of the flanges 23 and 24, between the first edge 22a and the second edge 22b of the web 22. The fastening projections 41 and 42 are small triangular pieces formed by cutting and bending. Openings 27 and 28 are formed in the web 22 at the base of the fastening projections 41 and 42. Opening 27 is formed by cutting and bending the fastening projection 41 from the web 22, and opening 28 is formed by cutting and bending the fastening projection 42 from the web 22.

[0032] The following provides a detailed explanation of how to use the marking tool 20. The holders 21 are attached to the brace 10 so that the brace 10 is fitted into the area enclosed by the web 22 and flanges 23 and 24 of each holder 21. Specifically, for each holder 21, the web 22 is placed against the front surface of the brace 10, and the flanges 23 and 24 are placed against the sides 11 and 12 of the brace 10, respectively, and the flanges 23 and 24 are used to clamp the brace 10 in the width direction.

[0033] When the holder 21 is attached, the fastening protrusions 41 and 42 penetrate the brace 10, thereby securing the holder 21 to the brace 10. Note that the fastening protrusions 41 and 42 do not necessarily have to be formed. In this case, the holder 21 may be secured to the brace 10 by fitting the brace 10 into the area surrounded by the web 22 and flanges 23 and 24.

[0034] As described above, when the holder 21 is attached to the brace 10, the marking projection 32 protrudes from the front surface of the brace 10 at the position of the side surface 11 of the brace 10, and the marking projection 33 protrudes from the front surface of the brace 10 at the position of the side surface 12 of the brace 10.

[0035] Multiple holders 21 attached to the brace 10 are arranged along the diagonals of the rectangular region 6.

[0036] After attaching the multiple holders 21, the insulation board 99 is fitted into the rectangular area 7 from the front to the back, and the insulation board 99 is brought into contact with the web 22. At this time, the marking protrusions 31 and 32 are inserted into the insulation board 99, and marks are formed on the insulation board 99. The marks are the traces left by the marking protrusions 31 and 32 being inserted.

[0037] After marking, the insulation board 99 is removed from the rectangular area 7. Then, the insulation board 99 is partially cut away. Specifically, the area between the line connecting the marks formed on the insulation board 99 by the marking projection 31 and the line connecting the marks formed on the insulation board 99 by the marking projection 32 is cut away. This cutting creates a band-shaped recess in the insulation board 99. Since the recess is formed using the marked marks as a guide, this recess conforms to the position and width of the bracing.

[0038] Next, without removing the marking tool 20 from the brace 10, or by removing the marking tool 20 from the brace 10, the insulation board 99 is placed into the rectangular area 7. At this time, the recess formed in the insulation board 99 is aligned with the brace 10, and the insulation board 99 is pushed from the front to the back, thereby placing the brace 10 into the recess.

[0039] After marking the insulation board to be placed in the rectangular area 8 in the same way, a recess is formed in the insulation board. Then, the recess formed in the insulation board is aligned with the brace 10, and the insulation board is pushed from the front to the back to fit the brace 10 into the recess in the insulation board.

[0040] Incidentally, the energy used from the production to the disposal of wood and paper materials is less than the energy used from the production to the disposal of metal or concrete materials. Therefore, because the building with frame 1 is made of wood, this building contributes to the realization of a decarbonized society by promoting carbon neutrality, which effectively reduces carbon dioxide emissions to zero, and to the achievement of the Sustainable Development Goals (SDGs).

[0041] Note that the width of the brace 10 may be wider than the distance between flanges 23 and 24. In that case, use the marking tool 20 as follows.

[0042] First, the web 22 is divided between the first edge 22a and the second edge 22b along a line parallel or oblique to the edges 22a and 22b. If a cutting line 29 is formed on the web 22, the web 22 may be divided along the cutting line 29. A tool may be used to divide the web 22.

[0043] Next, as shown in Figure 4, the divided parts 22c and 22d of the web 22 are placed against the front surface of the brace 10, and the flanges 23 and 24 are placed against the sides 11 and 12 of the brace 10, respectively, and the brace 10 is sandwiched in the width direction by the flanges 23 and 24. At this time, the fastening protrusions 41 and 42 are inserted into the brace 10, so the holder 21 is fastened to the brace 10.

[0044] Similarly, the other marking tools 20 are also divided, and the divided parts of the other marking tools 20 are attached to the braces 10.

[0045] Next, the insulation board 99 is fitted into the rectangular area 7 from the front to the back, and the insulation board 99 is brought into contact with the divided parts 22c and 22d of the web 22. At this time, the marking protrusions 31 and 32 are inserted into the insulation board 99, and marks are formed on the insulation board 99.

[0046] After removing the insulation board 99 from the rectangular area 7, the area between the line connecting the marks formed on the insulation board 99 by the marking projection 31 and the line connecting the marks formed on the insulation board 99 by the marking projection 32 is cut out from the insulation board 99.

[0047] Next, the insulation board 99 is placed in the rectangular area 7 without removing the divided parts of the marking tool 20 from the brace 10, or by removing the divided parts of the marking tool 20 from the brace 10. At this time, the recess formed in the insulation board 99 is aligned with the brace 10, and the insulation board 99 is pushed from the front to the back, thereby placing the brace 10 into the recess.

[0048] <Second Embodiment> Figures 5 and 6 are perspective views of the marking tool 120. The marking tool 120 comprises a holder 121, a plurality of marking projections 131, 132, and a fastening projection 141.

[0049] The grooved holder 121 has a web 122 and flanges 123, 124, similar to the holder 121 in the first embodiment. The thickness of the web 122 and flanges 123, 124 is greater than the thickness of the web 22 and flanges 23, 24 in the first embodiment. However, the thickness of the web 122 and flanges 123, 124 may be equal to the thickness of the web 22 and flanges 23, 24 in the first embodiment.

[0050] The marking projections 131 protrude from the first edge of the web 122 in the opposite direction to the rising direction of the flange 123. These marking projections 131 are spaced apart along the first edge 122a of the web 122. The marking projections 131 are tapered needles.

[0051] The marking projections 132 protrude from the second edge 122b of the web 122 in the opposite direction to the rising direction of the flange 124. These marking projections 132 are spaced apart along the second edge 122b of the web 122. The marking projections 132 are tapered needles.

[0052] The fastening projection 141 protrudes from the center of the web 122 in the same direction as the rising direction of the flanges 123 and 124, between the first and second edges of the web 122. The fastening projection 141 is a tapered needle. In the examples shown in Figures 5 and 6, there is one fastening projection 141. However, there may be multiple fastening projections 141.

[0053] Similar to the first embodiment, after marking the insulation board using the marking tool 120 described above, a recess is formed in the insulation board. Then, the recess formed in the insulation board is aligned with the brace 10, and the brace 10 is fitted into the recess in the insulation board by pushing the insulation board from the front to the back. Of course, the web 122 of the marking tool 120 may be divided along a line parallel or diagonal to the edges 122a and 122b between the first edge 122a and the second edge 122b, and the divided part of the marking tool 120 may be attached to the brace 10. Note that, as shown in Figures 4 and 5, if the web 122 and flanges 123 and 124 are thick, the marking tool 120 is removed from the brace 10 before installing the insulation board after marking.

[0054] The embodiments disclosed herein are for illustrative purposes only and do not limit the scope of the present invention. The scope of the present invention should be interpreted in accordance with the terms of the claims. [Explanation of symbols]
