[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-190173 Summary of the Invention [Problem to be solved by the invention]

[0004] The problem to be solved by the present invention is to provide a vertical frame material that can be used for installation not only for hanging fixtures but also for installations other than hanging fixtures, and that can be installed stably. [Means for solving the problem]

[0005] The following bracketed symbols refer to Figures 1 to 16:

[0006] In order to solve the above problems, according to claim 1, a vertical frame material (1) comprises a frame body (10) and a support material (40) attached to the frame body (10), wherein the frame body (10) comprises a band plate portion (11) formed in a band shape so as to have a width in the front direction, a thickness in the front direction, and a length in the vertical direction, and a protruding piece portion (20) integrally formed with the band plate portion (11), protruding in the front direction from a side end of the band plate portion (11) in the front direction, and having a thickness thinner than the thickness of the band plate portion (11), and the band plate portion (11) The side end surface (14) of the strip portion (11) in the projection direction has a groove (16) extending in the vertical direction, the support material (40) has an insertion portion (41) that is inserted into the groove (16) and a protrusion (42) that is formed integrally with the insertion portion (41) and protrudes from the groove (16), the convex piece portion (20) protrudes in the projection direction from the side end of the strip portion (11) beyond the tip end surface (43) of the protrusion (42), and a gap (48) is formed between the protrusion (42) and the convex piece portion (20).

[0007] According to claim 1 as described above, the convex piece portion (20) protrudes in the forward direction from the side end of the band plate portion (11) beyond the tip surface (43) of the protrusion portion (42). Therefore, when the support material (40) is removed from the frame main body (10), the convex piece portion (20) protrudes from the wall surface, and an installation can be achieved in which a step is formed between the wall surface and the end of the convex piece portion (20). Since the thickness of the protruding piece part (20) is thinner than the thickness of the band plate part (11), when the support material (40) is removed from the frame body (10), a fitting that makes the protruding piece part (20) look thin can be achieved. Because the insertion piece of the support material 40 is inserted into the groove 16, the deflection of the convex piece portion 20 is suppressed by the insertion portion 41. When the convex piece portion 20 comes into contact with the protruding portion 42, the convex piece portion 20 deflects, but further deflection of the convex piece portion 20 is suppressed by the protruding portion 42. Therefore, the insertion portion 41 and the protruding portion 42 of the support material 40 contribute to preventing damage to the convex piece portion 20. Since the protruding piece portion (20) protrudes in the front direction from the side edge of the band plate portion (11) beyond the tip surface (43) of the protruding portion (42), an attachment space for an auxiliary frame material or trim material is formed behind the protruding piece portion (20). By combining the auxiliary frame material or trim material with the protruding piece portion (20), a fit can be achieved that makes the frame body (10) appear thicker. Because the protruding piece portion (20) is supported by the auxiliary frame material or trim material, damage to the protruding piece portion (20) is prevented. When the strip portion (11) is placed against the mounting surface along the vertical edge of the wall opening and the vertical frame member (1) is attached to the vertical edge of the opening, the protrusion (42) of the support member (40) also comes into contact with the mounting surface, thereby stably mounting the support member (40) and the frame body (10). Since the gap 48 is formed between the protrusion 42 and the convex piece 20, the protrusion formed on the auxiliary frame member or trim member can be inserted into the gap 48. This contributes to stable installation of the auxiliary frame member or trim member.

[0008] According to claim 2, in the vertical frame material (1) described in claim 1, the band plate portion (11) has a flat visible surface (12) on its surface facing the viewing direction, the protrusion (42) bulges from the groove (16) and the insertion portion (41) toward the visible surface (12), and the protrusion (42) has a second visible surface (44) on the surface of its bulging portion facing in the same direction as the visible surface (12) and arranged flush with the visible surface (12).

[0009] According to claim 2, since the second visible / hidden surface (44) is flush with the visible / hidden surface (12), when the visible / hidden surface (12) is placed against a mounting surface along the vertical edge of the wall opening and the vertical frame member (1) is attached to the vertical edge of the opening, the second visible / hidden surface (44) is also placed against the mounting surface, thereby stably attaching the support member (40) and the frame body (10).

[0010] According to claim 3, in the vertical frame material (1) described in claim 2, a recess (46) is formed between the glimpse-hidden surface (12) and the second glimpse-hidden surface (44).

[0011] According to claim 3, when a flat-head screwdriver or a thin piece such as a blade is inserted into the recess 46 and a load is applied to the protrusion 42 in the forward direction by the thin piece, the insertion portion 41 is pulled out of the groove 16. This contributes to easy removal of the support member 40.

[0012] According to claim 4, in the vertical frame material (1) according to claim 2 or 3, the band plate portion (11) and the protruding piece portion (20) have a flat visible surface (13) on their surfaces that faces in the direction opposite to the direction in which the visible and hidden surface (12) faces. It has.

[0013] According to claim 5, the vertical frame material (1) of claim 1 further comprises a second support member (50) attached to the frame body (10), and the frame body (10) further comprises a second protruding piece (21) that is integrally formed with the band plate portion (11), protrudes from the side end opposite to the side end of the band plate portion (11) in a direction opposite to the protruding direction of the protruding piece portion (20), and has a thickness thinner than the thickness of the band plate portion (11), and the band plate portion (11) is provided with a front end surface (15) opposite to the side end surface (14) of the band plate portion (11). The second support material (50) has a second groove (17) extending in the vertical direction, and has a second insertion portion (51) inserted into the second groove (17) and a second protrusion portion (52) formed integrally with the second insertion portion (51) and protruding from the second groove (17), and the second convex piece portion (21) protrudes beyond the tip end surface (53) of the second protrusion portion (52) in a direction opposite to the protrusion direction of the convex piece portion (20), and a second gap (58) is formed between the second protrusion portion (52) and the second convex piece portion (21).

[0014] According to claim 6, in the vertical frame material (1) described in claim 5, the band plate portion (11) has a flat visible surface (12) on its surface facing the viewing direction, the protrusion (42) bulges from the groove (16) and the insertion portion (41) toward the visible surface (12), the protrusion (42) has a second visible surface (44) on the surface of its bulging portion that faces the same direction as the visible surface (12) and is provided flush with the visible surface (12), the second protrusion (52) bulges from the second groove (17) and the second insertion portion (51) toward the visible surface (12), and the second protrusion (52) has a third visible surface (54) on the surface of its bulging portion that faces the same direction as the visible surface (12) and is provided flush with the visible surface (12).

DETAILED DESCRIPTION OF THE INVENTION

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

[0020] <1. Vertical frame material> Fig. 1 is a cross-sectional view of a vertical frame material 1. Fig. 2 is an enlarged view of an area II shown in Fig. 1. Fig. 3 is an enlarged view of an area III shown in Fig. 1.

[0021] A rectangular opening in which the vertical frame member 1 is installed is formed in the wall of a building. A pair of vertical edges of the opening are vertical, and the upper and lower horizontal edges of the opening are horizontal. The wall in which the opening is formed is a partition wall or an exterior wall. A partition wall is a wall that separates an indoor space. An exterior wall is a wall that separates an indoor space from an outdoor space.

[0022] The vertical frame member 1 is installed on the vertical edge of the opening. The cross sections shown in Figures 1 to 3 are perpendicular to the projection direction and the front view direction. Here, projection refers to the width dimension of a member such as the vertical frame member 1, the projection direction refers to the depth direction of the opening, and the projection direction is parallel to the wall thickness direction. The front view refers to the thickness dimension of a member such as the vertical frame member 1, and the front view direction refers to the direction parallel to the width direction of the opening. The direction perpendicular to the projection direction and the front view direction is called the vertical direction.

[0023] The vertical frame material 1 is a thin, long plate having a width in the projection direction, a thickness in the front direction, and a length in the vertical direction. The horizontal cross-sectional shape of the vertical frame material 1, i.e., the cross-sectional shape perpendicular to the vertical direction, is uniform from the top to the bottom of the vertical frame material 1 and is line-symmetrical in the projection direction.

[0024] The vertical frame material 1 comprises a frame body 10 and two support materials 40, 50 attached to the frame body 10.

[0025] The frame body 10 is formed in the shape of a plate that is thin in the front direction and long in the vertical direction, so that it has a width in the front direction, a thickness in the front direction, and a length in the vertical direction. The overall length of the frame body 10 is sufficiently greater than the overall width of the frame body 10, and the overall width of the frame body 10 is greater than the overall thickness of the frame body 10. The horizontal cross-sectional shape of the frame body 10 is uniform from the top to the bottom of the frame body 10.

[0026] The frame body 10 is made of wood or resin, or a composite material of resin and wood fiber. The composite material may be, for example, medium density fiberboard (MDF), hardboard, particle board, an extrusion molding, or an injection molding. A decorative sheet may be attached to the entire surface or a part of the surface of the frame body 10.

[0027] The frame body 10 has a strip portion 11 and two protruding pieces 20, 21. The strip portion 11 and the protruding pieces 20, 21 are integrally formed. The band plate portion 11 has a width in the front-view direction, a thickness in the front-view direction, and a length in the vertical direction, and is formed as a band plate that is thin in the front-view direction and long in the vertical direction. The band plate portion 11 has a flat, visible surface 12 on its surface that faces the front-view direction. When the vertical frame material 1 is attached to the vertical edge of the opening, the visible surface 12 faces the inner surface of the opening along the vertical edge of the opening. Each of the side end surfaces 14, 15 of the band plate portion 11 in the front-view direction and the visible surface 12 form an external corner.

[0028] The protruding pieces 20 and 21 protrude in opposite directions from both ends of the band plate 11 in the projection direction. The protruding pieces 20 and 21 and the band plate 11 have a common projection surface 13 on their surfaces. The projection surface 13 is flat. The projection surface 13 faces in the opposite direction to the visible surface 12. The projection surface 13 is parallel to the visible surface 12. Because the projection surface 13 faces the inside of the opening, it is the design surface (the visible surface). The projection surface 13 faces the vertical edge opposite the vertical edge to which the vertical frame material 1 is attached. The distance from the projection surface 13 to the visible surface 12 corresponds to the thickness of the band plate 11 and the overall thickness of the vertical frame material 1 and the frame body 10. The protruding pieces 20 and 21 are formed in a band shape to have a thickness thinner than the thickness of the band plate 11.

[0029] The end faces 22, 23 of the protruding piece portions 20, 21 in the projection direction are both projection faces and design faces. A chamfer 18 is formed at the angle between the end face 22 of the protruding piece portion 20 and the projection face 13. Similarly, a chamfer 19 is formed at the angle between the end face 23 of the protruding piece portion 21 and the projection face 13. The chamfers 24, 25 are angular chamfers. However, the chamfers 24, 25 may also be rounded chamfers.

[0030] The convex piece portion 20 has a flat back surface 26 on the surface opposite to the visible surface 13. The back surface 26 faces in the same direction as the visible surface 12 and faces in the opposite direction to the visible surface 13. The distance from the visible surface 13 to the back surface 26 corresponds to the thickness of the convex piece portion 20. The back surface 26 and the end surface 22 form an external corner. Just as the convex piece portion 20 has a back surface 26, the convex piece portion 21 has a flat back surface 27 on the surface opposite to the visible surface 13.

[0031] The side end face 14 of the strip portion 11 in the projection direction and the back surface 26 of the protruding piece portion 20 form an inside corner. The opposite side end face 15 and the back surface 27 of the protruding piece portion 21 form an inside corner.

[0032] The frame body 10 has grooves 16 and 17 formed on the side end surfaces 14 and 15 of the band plate portion 11, respectively. The grooves 16 and 17 extend vertically from the upper to lower ends of the frame body 10 and the band plate portion 11. The grooves 16 and 17 are rectangular in cross section perpendicular to the vertical direction. The grooves 16 and 17 are slightly spaced, for example, by approximately 1 mm, from the back surfaces 26 and 27 of the protruding pieces 20 and 21 toward the visible surface 12. There is a step between the inner surface 18 of the groove 16, which is closer to the visible surface 13, and the back surface 26 of the protruding piece 20. There is also a step between the inner surface 19 of the groove 17, which is closer to the visible surface 13, and the back surface 27 of the protruding piece 21. However, the inner surface 18 of the groove 16 and the back surface 26 of the protruding piece 20 may be flush with each other, and the inner surface 19 of the groove 17 and the back surface 27 of the protruding piece 21 may also be flush with each other.

[0033] The support materials 40, 50 are made of wood or resin, or a mixture of resin and wood fiber material. The mixture may be MDF. The support materials 40, 50 may be molded products such as extrusion molded products or injection molded products. The composition or raw materials of the support materials 40, 50 may be changed to hard fiberboard, particle board, etc. The horizontal cross-sectional shape of the support materials 40, 50 is uniform from the upper end to the lower end of the vertical frame material 1.

[0034] The support material 40 is partially inserted into the groove 16 and partially protrudes from the groove 16. In other words, the support material 40 has an insertion portion 41 inserted into the groove 16 and a protrusion 42 protruding from the groove 16.

[0035] The insertion portion 41 and the protrusion 42 are integrally formed. The support material 40 is held in the frame body 10 by inserting the insertion portion 41 into the groove 16. The insertion portion 41 can be removed from the groove 16. The removed insertion portion 41 can be inserted into the groove 16 again.

[0036] When the insertion portion 41 is inserted into the groove 16, the protrusion 42 is positioned in the recessed corner formed by the side end surface 14 of the strip portion 11 and the back surface 26 of the convex piece portion 20. The protrusion 42 does not protrude as far as the end surface 22 of the convex piece portion 20, and the flat tip surface 43 of the protrusion 42 is positioned between the end surface 22 of the convex piece portion 20 and the side end surface 14 of the strip portion 11 in the projection direction. In other words, the convex piece portion 20 protrudes in the projection direction from the side end of the strip portion 11 in the projection direction beyond the tip surface 43 of the protrusion 42.

[0037] The protrusion 42 bulges from the groove 16 and the insertion portion 41 toward the visible surface 12 of the band plate portion 11, and the bulging portion contacts the side end surface 14 of the band plate portion 11. The protrusion 42 has a flat visible surface 44 on the surface of the bulging portion that faces the same direction as the visible surface 12 of the band plate portion 11. The visible surface 44 of the insertion portion 41 and the visible surface 12 of the band plate portion 11 are flush with each other. A recess 46 is formed between the visible surface 44 of the insertion portion 41 and the visible surface 12 of the band plate portion 11. Specifically, the insertion portion 41 has a notch in the region between the visible surface 44 of the insertion portion 41 and a surface 45 of the surface of the insertion portion 41 that contacts the side end surface 14 of the band plate portion 11, and the visible surface 44 of the insertion portion 41, and the notch forms the recess 46. When a thin piece such as a flat head screwdriver or blade is inserted into the recess 46 and a load is applied to the protrusion 42 in the forward direction by the thin piece, the insertion portion 41 is extracted from the groove 16.

[0038] The insertion portion 41 is spaced from the protruding piece portion 20 in the viewing direction on the back side of the protruding piece portion 20, and a gap 48 is formed between the insertion portion 41 and the protruding piece portion 20. The insertion portion 41 has a notch in the region between a surface 47 of the surface of the insertion portion 41 that contacts the back surface 26 of the protruding piece portion 20 and the visible surface 44 of the insertion portion 41, and the notch forms the gap 48.

[0039] The horizontal cross-sectional shape of support material 50 is symmetrical with respect to the horizontal cross-sectional shape of support material 40. Insertion portion 51, protrusion 52, tip surface 53, visible and hidden surface 54, surface 55, and surface 57 of support material 50 correspond to insertion portion 41, protrusion 42, tip surface 43, visible and hidden surface 44, surface 45, and surface 47 of support material 40, respectively. Recess 56 and gap 58 correspond to recess 46 and gap 48, respectively.

[0040] <2. Fit> The following describes a mounting structure using one or more vertical frame members 1. In the following description, the wall is a partition wall or exterior wall of a building constructed using the wood panel adhesive construction method. However, the wall may also be a partition wall or exterior wall of a building constructed using the post and beam construction method or the frame wall construction method. The wall may also be a fixture wall. A fixture wall is a frame made of wood or lightweight steel with gypsum board attached to one or both sides.

[0041] (1) Hakke fitting As shown in FIG. 4, a wall is mainly composed of wall panels 70, which are structural materials. The wall panels 70 are wooden panels. The wall panels 70 have a pair of vertical frames 71, a pair of horizontal frames connected between the upper and lower ends of the vertical frames 71, and face panels 72, 73 attached to both sides of a frame body made up of the vertical frames 71 and the horizontal frames. The wall panel 70 may have one or more wooden auxiliary beams attached to the frame body on the inside. The wall panel 70 may have a heat insulating material filled inside the frame body. In FIG. 4, one vertical frame 71 is shown, and the vertical frame 71 is aligned with one vertical edge of an opening 80 formed in the wall.

[0042] A wall is constructed by joining multiple wall panels 70 together to surround an opening 80. Mullions 74, which are wooden square timbers, are erected on both sides of the opening 80 and joined to the side end faces of the wall panels 70. The mullions 74 are adjustment materials used to adjust the width of the opening 80 to a design value. Strip-shaped boards 79 are attached to the faces of the mullions 74 that face the inside of the opening 80. The boards 79 are made of, for example, gypsum board or plywood. The boards 79 may be fire-resistant. The boards 79 form the inner surfaces of the opening 80 along the vertical edges of the opening 80. Note that the mullions 74 may not be provided, and the boards 79 may be attached to the side end faces of the wall panels 70.

[0043] The support materials 40, 50 are removed from the frame body 10. The visible and hidden surface 12 of the band plate portion 11 faces the board 79 and contacts it, and fasteners 77, 78 such as finish nails or screws are driven into the frame body 10 from both wall surfaces of the wall, thereby fixing the frame body 10 to the inner surface of the opening 80. The visible and hidden surface 12 of the band plate portion 11 may be adhered to the inner surface of the opening 80. The visible and hidden surface 12 of the band plate portion 11 may be joined to the inner surface of the opening 80 using a combination of the fasteners 77, 78 and an adhesive.

[0044] In addition, the mullions 74 and boards 79 may not be provided, the visible and hidden surfaces 12 of the strip portions 11 may contact the side end surfaces of the wall panels 70, and the frame body 10 may be fixed to the side end surfaces of the wall panels 70 by fasteners 77, 78.

[0045] The width of the strip portion 11 in the projection direction is equal to the thickness of the wall. The side end faces 14 and 15 of the strip portion 11 are flush with both wall surfaces of the wall.

[0046] Boards 75 and 76 are attached to both wall surfaces of the wall. Boards 75 and 76 may have cloth attached to their surfaces. Boards 75 and 76 protrude into the interior surface of the opening, i.e., from board 79. These protruding portions contact side end surfaces 14 and 15 of strip portion 11, respectively, and grooves 16 and 17 are hidden behind these protruding portions. These protruding portions may be glued to side end surfaces 14 and 15 of strip portion 11. Grooves 16 and 17 may be filled with a filler such as resin.

[0047] The side end faces of the boards 75, 76 are abutted against the rear faces 26, 27 of the protruding pieces 20, 21. The side end faces of the boards 75, 76 may be bonded to the rear faces 26, 27 of the protruding pieces 20, 21.

[0048] The thickness of the board 75 is smaller than the protruding width of the convex piece portion 20 from the side end face 14 of the strip portion 11 to the end face 22 of the convex piece portion 20, and the convex piece portion 20 protrudes in the forward direction beyond the board 75. A step is formed between the surface of the board 75 and the end face 22 of the convex piece portion 20. Similarly, the thickness of the board 76 is smaller than the protruding width of the convex portion 21 from the side end face 15 of the strip portion 11 to the end face 23 of the convex portion 21, and the convex portion 21 protrudes from the board 76 in the forward direction.

[0049] As shown in (2) below, board 75 may not overhang the inner surface of the opening, i.e., board 79, into the opening, and the side end surface of board 75 may be spaced apart from rear surface 26 of protruding piece portion 20. This will be explained in detail below.

[0050] (2) Finishing using trim 5, the support material 40 is not removed, and the inserting portion 41 of the support material 40 is inserted into the groove 16, thereby holding the support material 40 in the frame body 10. The protruding portion 42 of the support material 40 is disposed in the region between the side end surface of the board 75 and the back surface 26 of the protruding piece portion 20.

[0051] The side end surfaces of the board 75 are in surface contact with the protruding portions 42 of the support material 40, particularly the visible and hidden surfaces 42. The side end surfaces of the board 75 may be joined to the protruding portions 42 with adhesive or double-sided adhesive tape. The surface of the board 75 and the tip surfaces 43 of the protruding portions 42 are flush with each other.

[0052] The parting material 91 fits into the recessed corner formed by the tip surface 43 of the protrusion 42 and the back surface 26 of the convex piece portion 20. The parting material 91 extends vertically along the convex piece portion 20. The horizontal cross-sectional shape of the parting material 91, that is, the cross-sectional shape perpendicular to the vertical direction, is rectangular, and the cross-sectional shape is uniform from the top end to the bottom end of the parting material 91. The dimension of the parting material 91 in the visible direction is greater than the dimension of the parting material 91 in the visible direction.

[0053] The parting material 91 is in surface contact with the back surface 26 of the protruding piece portion 20. The parting material 91 may be joined to the back surface 26 of the protruding piece portion 20 with an adhesive or double-sided adhesive tape.

[0072] FIG. 10 is an enlarged view of the region X shown in FIG. Board 75A does not protrude from board 79A into opening 202, and the side end surface of board 75A is spaced apart from rear surface 26A of protruding piece portion 20A. The side end surface of board 75A is in surface contact with protruding portion 42A of support material 40A. The side end surface of board 75A may be joined to protruding portion 42A with an adhesive or double-sided adhesive tape.

[0073] A visible surface 12D of the strip portion 11D is in surface contact with the inner surface of the opening 202, that is, the surface of the board 75A. The visible surface 12D may be joined to the surface of the board 75A with an adhesive or double-sided adhesive tape.

[0074] A protruding piece portion 21D projects from the side end surface of the board 75A. The protruding piece portion 21D is spaced apart from the protruding portion 42A, and a back surface 27D of the protruding piece portion 21D faces the tip surface 43A of the protruding portion 42A.

[0075] A protruding portion 52D of the support material 50D is in surface contact with the inner surface of the opening 202, that is, the surface of the board 75A. The support material 50D is fixed to the board 75A by a fastener 79D.

[0076] A protruding piece portion 20A protrudes from the surface of the board 75. The protruding piece portion 21A is spaced apart from the protruding portion 52D, and the back surface 26A of the protruding piece portion 20A faces the tip surface 53A of the protruding portion 52A.

[0077] A space is formed surrounded by protrusion 20A, protrusion 42A, protrusion 21D, and protrusion 52D. The space is open to the outside through a gap between the corner formed by end face 22A of protrusion 20A and back face 26A and the corner formed by end face 23D of protrusion 21D and back face 27D. A parting material 900, which is an auxiliary frame material, is placed in the space.

[0078] FIG. 11 is a horizontal cross-sectional view of the parting material 900. The length of the parting material 900 in the vertical direction corresponds to the length of the frame main bodies 11A and 11D in the vertical direction. For example, the length of the parting material 900 in the vertical direction is equal to the length of the frame main bodies 11A and 11D in the vertical direction.

[0079] The parting material 900 has a main body 901 , an insertion piece 902 and a protrusion 903 . The main body 901 is formed to be long in the vertical direction. The cross-sectional shape of the main body 901 is rectangular. One corner 912 of the main body 901 is chamfered, and in the example shown in FIG. 11 , the chamfer is a square chamfer. However, the chamfer may be a rounded chamfer. A corner 913 opposite the corner 912 is also chamfered, and the chamfer is a square chamfer. However, the chamfer of the corner 913 may be a rounded chamfer. The chamfered area of the corner 913 is narrower than the chamfered area of the corner 912.

[0080] Insertion piece 902 protrudes from corner 914 of main body 901 in the direction from corner 913 to corner 914. The protruding direction of insertion piece 902 is perpendicular to the vertical direction. Insertion piece 902 has multiple constrictions to reduce its thickness.

[0081] The protrusion 903 protrudes from a corner 915 of the main body 901 in a direction from the corner 913 toward the corner 915. The protrusion direction of the protrusion 903 is perpendicular to the vertical direction. The protrusion direction of the protrusion 903 is perpendicular to the protrusion direction of the insertion piece 902.

[0082] The protrusion 903 has notches 931 and 932 on both sides of the protrusion 903 at positions closer to the main body 901. The notches 931 and 932 are V-shaped. When the protrusion 903 is bent sideways, the protrusion 903 is cut at the positions of the notches 931 and 932, and a tip end 934 of the protrusion 903 is separated from a residual protrusion 933, which is the base end of the protrusion 903. The residual protrusion 933 also protrudes from a corner 915 of the main body 901 in a direction from the corner 913 toward the corner 915.

[0083] As shown in FIG. 10 , the main body 901 of the parting material 900 is contained within a space surrounded by the protruding piece 20A, the protruding piece 42A, the protruding piece 21D, and the protruding piece 52D. The main body 901 is in surface contact with the back surface 26A of the protruding piece 20A. The main body 901 is in surface contact with the back surface 27D of the protruding piece 21D. A corner 913 of the main body 901 protrudes from the space through the gap between the corner formed by the end surface 22A and the back surface 26A of the protruding piece 20A and the corner formed by the end surface 23D and the back surface 27D of the protruding piece 21D. Therefore, part of the main body 901 is visible. That is, part of the surface from the corner 913 to the corner 915 is visible from inside the opening 102, and part of the surface from the corner 913 to the corner 914 is visible from inside the opening 202.

[0084] The insertion piece 902 of the trim 900 is inserted into the gap 58D between the protrusion 52D and the convex piece 21D. The insertion piece 902 is in contact with the protrusion 52D and the convex piece 21D, and is slightly compressively deformed by the protrusion 52D and the convex piece 21D. The compressive deformation of the insertion piece 902 prevents the insertion piece 902 from slipping out of the gap 58D. The convex piece 903 is inserted into the gap 48A between the protrusion 42A and the convex piece 20A. The convex piece 903 is in contact with the convex piece 20A, but is spaced apart from the protrusion 42A.

[0085] Alternatively, the trim 900 may be turned upside down, with the insertion piece 902 inserted into the gap 48A between the protrusion 42A and the convex piece 20A, and the convex piece 903 inserted into the gap 58D between the protrusion 52D and the convex piece 21D.

[0086] FIG. 12 is an enlarged view of region XII shown in FIG. The protrusion 42D of the support material 40D is in surface contact with the inner surface of the opening 202, i.e., the surface of the board 75A. The support material 40D is fixed to the board 75 by a fastener 77D. The protruding piece portion 20D is spaced from the surface of the board 75A, and the back surface 26D of the protruding piece portion 20D faces the surface of the board 75A. A parting material 800, which is an auxiliary frame material, is placed in the space between the back surface 26D of the protruding piece portion 20D and the surface of the board 75A. The length of the parting material 800 in the vertical direction corresponds to the length of the frame main body 11D in the vertical direction. For example, the length of the parting material 800 in the vertical direction is equal to the length of the frame main body 11D in the vertical direction.

[0087] Like the parting material 900, the parting material 800 has a main body 801 and an insert piece 802. The combination of the main body 801 and the insert piece 802 of the parting material 800 has a shape symmetrical to the combination of the main body 901 and the insert piece 902 of the parting material 900.

[0088] Parting material 800 is obtained by cutting off tip portion 934 of protrusion 903 from parting material 900 and then turning it upside down. Therefore, parting material 800 has a remaining protrusion 833 at corner 815 of main body portion 801 that faces corner 814 of main body portion 801 to which the base end of insertion piece 802 is connected.

[0089] The main body 801 of the parting material 900 is contained in the space between the back surface 26D of the protruding piece portion 20D and the surface of the board 75A. The main body 801 is in surface contact with the back surface 26D of the protruding piece portion 20D. The main body 801 is in contact with the surface of the board 75A. The remaining protrusion 833 is either crushed by the board 75A or slightly protrudes into the surface of the board 75A. The main body 801 protrudes from the space between the back surface 26D of the protruding piece portion 20D and the surface of the board 75A beyond the end surface 22D of the protruding piece portion 20D.

[0090] Insertion piece 802 of parting material 800 is inserted into gap 48D between protrusion 42D and convex piece 20D. Insertion piece 802 is in contact with protrusion 42D and convex piece 20D, and is slightly compressively deformed by protrusion 42D and convex piece 20D. The compressive deformation of insertion piece 802 prevents insertion piece 802 from slipping out of gap 48D.

[0091] 8, frame body 10B is attached to the vertical edge of opening 102 symmetrically to frame body 10A with respect to the vertical center plane of opening 102. A vertical frame member consisting of frame body 10E and support members 40E, 50E is attached to the surface of board 76B symmetrically to the vertical frame member consisting of frame body 10D and support members 40E, 50E with respect to the vertical center plane of opening 102. Frame body 10D is used as a trim material.

[0092] The parting material 900E is attached to the space surrounded by the protruding piece portions 21B, 20E of the frame bodies 10B, 10E and the support materials 50B, 40E, symmetrically to the parting material 900 with respect to the vertical central plane of the opening 102. The parting material 900E has a shape symmetrical to the shape of the parting material 900 with respect to the vertical central plane of the opening 102.

Summary> (1) Since the convex piece portion 20 protrudes in the forward direction from the side end of the strip portion 11 beyond the tip surface 43 of the protrusion 42, when the support material 40 is removed from the frame body 10, as shown in Figure 4, the convex piece portion 20 protrudes from the surface of the board 75, and an installation can be achieved in which a step is formed between the surface of the board 75 and the end surface 22 of the convex piece portion 20.

[0112] (2) Since the thickness of the protruding piece portion 20 is thinner than the thickness of the band plate portion 11, when the support material 40 is removed from the frame body 10, a fitting can be achieved in which the protruding piece portion 20 appears thin, as shown in Figure 4.

[0113] (3) Because the insertion piece of the support material 40 is inserted into the groove 16, bending of the convex piece portion 20 is suppressed by the insertion portion 41. Because the protruding portion 42 protrudes from the groove 16, bending of the convex piece portion 20 occurs until the convex piece portion 20 hits the protruding portion 42, but does not go any further. Therefore, the insertion portion 41 and the protruding portion 42 of the support material 40 contribute to preventing damage to the convex piece portion 20.

[0114] (4) Because the protruding piece portion 20 protrudes in the front direction from the side end of the band plate portion 11 beyond the tip end surface (43) of the protruding portion 42, as shown in FIG. 5, an attachment space for a trim 91 is formed behind the protruding piece portion 20. By combining the trim 91 with the protruding piece portion 20, a fit can be achieved that makes the frame body 10 appear thicker. Similarly, as shown in FIG. 9, by combining the trim 800 with the protruding piece portion 20D, a fit can be achieved that makes the frame body 10D appear thicker. Because the protruding piece portions 20, 20D are supported by the trim 91 and the trim 800, respectively, damage to the protruding piece portions 20, 20D is prevented.

[0115] (5) As shown in Figure 10, when two vertical frame members 11A, 11D are arranged at right angles, an attachment space for a trim 900 is formed behind the protruding pieces 20A, 21D. By combining the trim 900 with the protruding piece 20A, a fit can be achieved that makes the appearance of the frame body 10A appear thicker. By combining the trim 900 with the protruding piece 21D, a fit can be achieved that makes the appearance of the frame body 10D appear thicker.

[0116] (6) As shown in Figure 5, when the strip portion 11 is placed against the mounting surface along the vertical edge of the wall opening 80 and the vertical frame member 1 is attached to the vertical edge of the opening 80, the protruding portion 42 of the support member 40 also comes into contact with the mounting surface. This stabilizes the mounting of the support member 40 and the frame body 10.

[0117] (7) Since the gap 48A is formed between the protrusion 42A and the convex piece portion 20A, the convex portion 903 formed on the parting material 900 can be inserted into the gap 48A. This contributes to the stable installation of the parting material 900.

[0118] (8) As shown in Figure 5, the visible and hidden surfaces 44 of the protrusions 42 are flush with the visible and hidden surfaces 12 of the band plate portions 11. Therefore, when the visible and hidden surfaces 12 are placed against the mounting surface along the vertical edge of the wall opening 88 and the vertical frame member 1 is attached to the vertical edge of the opening 80, the visible and hidden surfaces 44 of the protrusions 42 are also placed against the mounting surface. This ensures stable attachment of the support member 40 and the frame body 10.

[0119] (9) By inserting a flathead screwdriver or a thin piece such as a blade into the recess 46, the support material 40 can be easily removed from the frame body 10.

[0120] (10) The energy used from the production to the disposal and discarding of wood is less than the energy used from the production to the disposal and discarding of metal or concrete materials. Therefore, if the frame body 10, the support material 40, or the support material 50, or two or more of these are made of wood, the vertical frame material 1 will contribute to the realization of a decarbonized society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and to the achievement of the Sustainable Development Goals (SDGs).
