Description

[Technical field]

[0001] The present invention relates to a lining structure between a vertical frame and an adjacent interior wall at an inside corner viewed from the indoor side, and a construction method thereof. [Background technology]

[0002] When an opening is provided near an inside corner of a building, there is a situation where a gap is formed between the frame installed in the opening and the interior wall adjacent to the frame, and it is necessary to fill the gap for design reasons, etc.

[0003] Therefore, Patent Document 1 describes a structure and construction method that allows general sashes to be installed close together in indoor corners, and sealants are used to fill the gaps between the sash frame and the trim material, and between the two trim materials. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2008-184818 Summary of the Invention [Problem to be solved by the invention]

[0005] However, if a wet material such as sealant is used to fill the gap between the frame and the interior wall, the sealant may become dirty, break, or peel off due to deterioration over time caused by the shaking of the building or frame, which could cause problems with the design.

[0006] In view of the above problems, the present invention aims to provide a frame edge structure and a construction method thereof that fills the gap between a frame and an interior wall in a dry manner at an inside corner of a building. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the present invention provides a frame trim structure at an inside corner on the indoor side, the inside corner being formed from a first inner wall having an opening and arranged on the indoor side, and a second inner wall perpendicular to the first inner wall and arranged on the indoor side, the opening being provided at the side end of the first inner wall on the inside corner side, the second inner wall, and a frame arranged around the periphery of the opening, a first vertical frame extending vertically on the inside corner side, a first vertical engagement groove being provided in the longitudinal direction on the surface of the first vertical frame on the second inner wall side, a frame fixing plate that is fitted into and fixed in the first vertical engagement groove, and a trim material that is fixed to the first vertical frame adjacent to the indoor side of the frame fixing plate, the frame fixing plate and the trim material being fixed to the first vertical frame so as to be flush with each other, and the flush surfaces of the frame fixing plate and the trim material are fixed to the second inner wall.

[0008] Another feature of the present invention is that a step is provided between the indoor surface of the trim material and the indoor surface of the first vertical frame.

[0009] Another feature of the present invention is that the parting material has a lead groove in the longitudinal direction at the center of the surface on the second inner wall side.

[0010] Another feature of the method is that the steps of constructing the second inner wall, fixing a trim material and a frame fixing plate to the first vertical frame, and attaching and constructing the frame so that the trim material and frame fixing plate fixed to the first vertical frame are adhesively fixed to the second inner wall are carried out in that order. Effect of the Invention

[0011] The frame edge structure of the present invention, having the above-mentioned configuration, can dry-cut the second inner wall and the frame, and further, by fitting and fixing a frame fixing plate into the first vertical engagement groove provided in the longitudinal direction on the surface of the inside corner side of the first vertical frame, it is possible to use even a frame used in general areas in the inside corner area.

[0012] In addition, since a step is provided between the trim material and the first vertical frame, this has the effect of preventing the gap between the trim material and the first vertical frame from appearing as if there is a crack.

[0013] In addition, the center of the second inner wall surface of the trim has a lead groove in the longitudinal direction, and nails can be driven into the first vertical frame along the lead groove, so that nails can be driven into the first vertical frame from the center line of the trim, and the groove shape has the effect of making the nail less likely to slip when driven.

[0014] Furthermore, since the trim material is not installed last but rather is fixed to the first vertical frame first, there is no risk of the trim material not being able to fit into the gap formed by the second inner wall, the frame fixing plate, and the first vertical frame.

[0016] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. Note that each embodiment is merely one embodiment of the present invention, and the embodiment can be changed without changing the gist of the present invention. In this specification, the width, height, and depth are the width in the width direction, the height direction, and the depth direction based on the viewpoint of a person inside the room.

[0017] (Regarding the frame edge structure 100) As shown in Fig. 1, the frame edge structure 100 is a edge structure of a first vertical frame 3a extending vertically on the inside corner 1 side of a frame 3 on the periphery of an opening 2 provided near an inside corner 1 when viewed from the indoor side, and a second inner wall 5. Fig. 2 shows an example of a cross section of the frame edge structure 100 according to the present invention, and the frame edge structure 100 mainly has a first vertical frame 3a, a frame fixing plate 4, a second inner wall 5, and a trim material 6. In this embodiment, the inside corner portion 1 of the frame edge structure 100 includes an inside corner portion 1 that is an inside corner portion 1 when viewed from the indoor side, but is an outside corner portion when viewed from the outdoor side, as shown in Figure 2, and an inside corner portion 1 that is formed from a first inner wall 7 and a second inner wall 5 provided on the partition wall 7a, and in which the outer wall surface W is flat when viewed from the outdoors, and does not become an outside corner portion, as shown in Figure 3.

[0018] (About the interior walls) The first inner wall 7 and the second inner wall 5, which are inner walls, are inner wall surface materials arranged on the indoor side, and are gypsum boards or the like. As shown in FIG. 1, the first inner wall 7, which has an opening 2 and is arranged on the indoor side, and the second inner wall 5, which is perpendicular to the first inner wall 7 and arranged on the indoor side, form an inside corner 1. The surface of the inner wall is cross-cut. As described later, the cross-cut of the second inner wall 5 is performed after the frame 3 is installed, so that the cross-cut of the second inner wall 5 is performed up to the edge of the trim material 6 fixed to the frame 3, and a sealant or the like is applied between the cross-cut and the trim material 6 to close the gap. The second inner wall 5 is fixed to the second interior base material C2 with screws or the like, and a heat insulating material B is provided around the first interior base material C1 and the second interior base material C2.

[0019] As will be described later, when constructing the frame, adhesive 8 is applied in advance to the surface of the second inner wall 5 where the frame fixing plate 4 and the trim material 6 come into contact, so that the frame 3 is pressed against the sash frame 9a of the sash 9 to fit the frame 3, and at the same time the first vertical frame 3a is adhesively fixed to the second inner wall 5. Also, if the adhesive 8 is applied too close to the indoor side of the second inner wall 5, there is a risk that the adhesive 8 will overflow from between the trim material 6 and the second inner wall 5 when the frame is constructed and the frame 3 is attached, so the adhesive 8 is not applied near the indoor side.

[0020] 2, there is a gap S between the first interior base material C1, which extends vertically and to which the end of the second inner wall 5 is butted, and the first vertical frame 3a. By having the gap S, it is possible to prevent interference during construction due to distortion of the first interior base material C1 when constructing the frame 3.

[0021] (Regarding opening 2) The first inner wall 7 has an opening 2. The opening 2 is provided at a position that is the side end of the first inner wall 7 on the inside corner 1 side. Therefore, the first inner wall 7 has a roughly U-shape because the opening 2 is located at the side end. In this embodiment, the opening 2 is located in the middle of the left end, but it may be located at either the left or right side end of the first inner wall 7 on the inside corner 1 side, or it may naturally be located at both ends, and the top and bottom positions are not particularly limited.

[0022] The opening 2 may be provided in an inner wall that separates the inside of a building from the outside, or may be used as a partition wall in a building that separates the inside of the building from a corridor adjacent to the inside of the building or another inside of the building. The opening 2 is provided with a sash 9, which is a window frame, and a closure member 10, such as a fitting or window member that closes or opens the opening, is attached to the sash 9. As the fitting of the closure member 10, a hinged door, a sliding door, a folding door, or the like is used. In addition to these, a storm shutter or a screen door may be provided. When the closure member 10 is a window member, it is not limited to a waist window, and may be a skylight or a bay window. Depending on the type of the closure member 10, the rail, end accommodation portion (door stop groove), rotating connection member, slide connection arm, or the like of the closure member 10 may be used as appropriate. The sash 9 is provided with a sash frame 9a around its four periphery for fixing the frame 3. The frame 3 is fitted into the sash frame 9a and fixed to the frame 3 from the sash frame 9a using fixing members 13.

[0023] On the outdoor side of the opening 2, a mounting base (not shown) is provided, which has approximately the same shape as the opening 2 to which the sash 9 is attached, and which defines all four sides in the same way as the opening 2. The horizontal members of the mounting base are the runners, lintels, etc. that define the upper side, and the window sills, etc. that define the lower side, and the floor base, while the vertical members of the mounting base are the columns, studs, etc. that define the left and right sides.

[0024] (About frame 3) As shown in Figs. 6 and 7, the frame 3 is a rectangular frame body in which a first vertical frame 3a and a second vertical frame 3b, each of which has the same shape, and a first horizontal frame 3c and a second horizontal frame 3d, each of which has the same shape, are combined. A trim material 6 and a frame fixing plate 4 are fixed to the first vertical frame 3a, and the frame is arranged on the periphery of the opening 2 of the first inner wall 7. The first vertical frame 3a is one of the frames 3 arranged on the periphery of the four sides of the opening 2, which extends vertically and is provided on the inside corner 1 side. The second vertical frame 3b is provided on the opposite side to the inside corner 1 side, parallel to the first vertical frame 3a. The first horizontal frame 3c is provided on the upper side of the opening 2, and the second horizontal frame 3d is provided on the lower side. The corners of the frame 3 are rounded. In this embodiment, the visible corners of the frame 3 are chamfered by 2 mm.

[0025] As shown in Figs. 6 and 7, the frame 3 has engagement grooves 11 in the longitudinal direction on the outer periphery thereof for engaging with the adjacent first inner wall 7. The engagement grooves 11 have a first vertical engagement groove 11a, a second vertical engagement groove 11b, a first horizontal engagement groove 11c, and a second horizontal engagement groove 11d for the first vertical frame 3a, the second vertical frame 3b, the first horizontal frame 3c, and the second horizontal frame 3d, respectively. In this embodiment, the opening 2 is provided at the side end of the first inner wall 7 on the inside corner 1 side, and the first vertical frame 3a located on the inside corner 1 side of the frame 3 does not have an adjacent first inner wall 7, so the first inner wall 7 is not engaged with the first vertical engagement groove 11a provided in the longitudinal direction on the surface 12a on the second inner wall side of the first vertical frame. The frame fixing plate 4 is fixed to the first vertical engagement groove 11a, as described later. As shown in FIG. 2, a surface 12b on the opening side of the first vertical frame and a sash frame 9a of a sash 9 provided in the opening 2 are fixed by a fixing member 13 such as a screw.

[0026] In addition, an airtight material 14 is provided on the surface 12c of the first vertical frame facing the outside. The airtight material 14 is made of a flexible material that can be compressed without any problems, and prevents gaps between the first vertical frame 3a and the sash 9, improving airtightness indoors.

[0027] (Regarding trim 6) The trim material 6 divides the second inner wall 5 and the first vertical frame 3a, and is fixed to the first vertical frame 3a adjacent to the frame fixing plate 4. The width of the trim material 6 is about 5 mm, which is the width from the first vertical frame 3a to the second inner wall 5, the height is the same as the first vertical frame 3, and the depth is about 10 mm, which is 1 mm to 3 mm shorter than the length from the frame fixing plate 4 to the first vertical frame 3a. The trim material 6 has a bar material 6a and a sheet member 6b that partially covers the periphery of the bar material 6a. The trim material 6 is fixed to the surface 12a of the second inner wall side of the first vertical frame adjacent to the frame fixing plate 4 with a finish nail so as to have a constant pitch using a stabilizer or the like.

[0028] Furthermore, when the trim material 6 is fixed to the first vertical frame 3a, it is fixed so that there is a step 16 of 1 mm to 3 mm between the indoor surface 15 of the trim material and the indoor surface 12d of the first vertical frame, as shown in Fig. 5(b). If there was no step 16, the first vertical frame 3a and the trim material 6 would be flush on the indoor side, and when a person inside looks at the first vertical frame 3a, they would recognize the first vertical frame 3a and the trim material 6 as components of a single vertical frame, and the vertical line at the boundary between the first vertical frame 3a and the trim material 6 would make the first vertical frame 3a appear to be split vertically. Therefore, by providing the trim material 6 with a step 16 of 1 mm to 3 mm in relation to the first vertical frame 3a, people indoors will recognize the trim material 6 and the first vertical frame 3a as separate members, and the first vertical frame 3a will not appear to be cracked. In this embodiment, the step 16 is provided on the trim material 6 so that it is on the depth side of the first vertical frame 3a, but if necessary, the step 16 may be provided so that the trim material 6 is on the front side of the first vertical frame 3a.

[0029] The corners of the trim 6 may be rounded. In this embodiment, the corners are chamfered to a radius of about 0.5 mm. By chamfering the corners of the trim 6 to make them round, it is possible to further reduce the appearance of a crack from the first vertical frame 3a. Furthermore, by chamfering the corners of the first vertical frame 3a adjacent to the trim 6, it is possible to further reduce the appearance of a vertical crack between the trim 6 and the first vertical frame 3a.

[0030] As shown in FIG. 5(a) and FIG. 6(b), the bar 6a has a vertically long shape, and a lead groove 6c that is linear in the length direction and V-shaped in cross section is provided in the center. The lead groove 6c serves as a guide when the installer uses a stable or the like to finish-nail the fixing member 13 such as a nail from the bottom of the lead groove 6c to the first vertical frame 3a, and since the lead groove 6c is linear, the fixing member 13 can be driven into the first vertical frame 3a in a straight line without any left-right deviation. In addition, since the lead groove 6c is V-shaped in cross section, the fixing member 13 is less likely to shift left-right when driven in. Furthermore, after the fixing member 13 is driven in, the head 13a of the fixing member 13 is embedded in the lead groove 6c, so that the head 13a does not interfere with the second inner wall 5 adjacent to the trim material 6. In this way, the lead groove 6c is effective before, during, and after the fixing member 13 is driven in. In addition, when the frame 3 is installed, the adhesive 8 applied to the second inner wall 5 enters into the lead groove 6c, which has the effect of preventing the adhesive 8 from coming out to the indoor side.

[0031] By driving the fixing member 13 into the surface 12 on the second inner wall side of the first vertical frame 3a from the side of the trim 6, the head of the fixing member 13 does not protrude from the surface of the first vertical frame 3a, thereby improving the design of the first vertical frame 3a. The lead groove 6c does not have to be V-shaped in cross section, but may be U-shaped or concave in cross section, and the shape of the lead groove 6c is not particularly limited. In this embodiment, the lead groove 6c is provided so that the angle of the V in the V-shape in cross section is 90 degrees, but the angle is not particularly limited as long as the fixing member 13 can be driven in accurately.

[0032] The material of the rod 6a is preferably medium density fiberboard (MDF), which is a board made by boiling wood chips that have been processed finely into fibers, adding synthetic resin, and molding it, but other materials such as plywood, synthetic resin, or elastomer may also be used, and the material is not particularly limited. By making it from a synthetic resin material, it is possible to improve the heat insulation and suppress condensation.

[0033] As shown in FIG. 5(a), in order to make the sheet member 6b visible when viewed from the indoor side, the sheet member 6b is attached only to the visible portion 6d, which is one side of the bar material 6a exposed to the indoor side, and is attached so as not to cover the lead groove 6c of the bar material 6a. The sheet member 6b is formed of an olefin-based material such as polyethylene (PE) or polypropylene (PP). In this embodiment, the color of the sheet member 6b is approximately the same as that of the first vertical frame 3a. By using a color approximately the same as that of the first vertical frame 3a, the trim material 6 is integrated with the first vertical frame 3a, and the design of the trim structure 100 of the frame can be improved. The color of the sheet member 6b does not have to be approximately the same as that of the first vertical frame 3a, and any color may be used. For example, a gradation may be created by using an intermediate color between the first vertical frame 3a and the second inner wall 5. The color tone may also be the same as that of the first vertical frame 3a, for example, a wood grain tone.

[0034] Furthermore, since the sheet member 6b is attached only to the visible portion 6d, which is one side of the bar 6a, and does not cover the lead groove 6c, the fixing member 13 can be driven in without interfering with the sheet member 6b when the sheet member 6b is fixed with a finish nail using a stable or the like. In this embodiment, the fixing member 13 is fixed with the finish nail using a fixing member 13 such as a nail, but if there is no problem in construction, an adhesive or the like may be used instead of the fixing member 13 or in addition to the finish nail fixing.

[0035] Also, as shown in FIG. 5(b), when the bar 6a is covered with the sheet member 6b, the portion covered with the sheet member 6b may be formed thinner by the thickness of the sheet member 6b. A step 6h is provided between one side of the bar 6a and the other side of the bar 6a covered with the sheet member 6b. By providing the step 6h, the width of the bar 6a is formed thinner from H1 to H2. Specifically, since the thickness of the sheet member 6b is about 0.05 mm, the width H2 of the visible portion 6d on one side of the bar 6a is formed thinner by about 0.05 to 0.1 mm than the width H1 on the other side. The width H3 of the sheet member 6b is formed to be the same as H1. Therefore, when the bar 6a covers the sheet member 6b, no step is generated between the bar 6a and the sheet member 6b, and the bar 6a is formed so as to be flush.

[0036] In this embodiment, the sheet member 6b is provided on one side of the bar 6a, but it does not have to be on one side, and the sheet member 6b may be provided only on the indoor surface of the bar 6a and the rounded corners at both ends thereof.

[0037] On the edge surfaces 6e at the top and bottom ends of the trim material 6, sealing members 6f are provided that are substantially the same color as the sheet member 6b and have the same shape as the edge surfaces 6e. By providing the sealing members 6f, the edge surfaces 6e become less noticeable when the frame edge structure 100 is viewed from above or below, improving the design. If the trim material 6 is made of a synthetic resin or elastomer, etc., and the edge surfaces 6e and the side surfaces are the same color, the sealing members 6f do not need to be used.

[0038] The trim material 6 is fixed to the second inner wall 5 by an adhesive 8. The surface to which the adhesive 8 is applied is the surface on the second inner wall 5 side, i.e., the surface 6g of the trim material that is flush with the adjacent frame fixing plate 4. If the adhesive 8 is applied to the frame fixing plate 4 side or the trim material 6 side rather than to the second inner wall 5 side, when the frame 3 is attached and pressed into the sash frame 9a, there is a possibility that the adhesive 8 will overflow onto the interior side, and therefore it is preferable to apply the adhesive 8 to the second inner wall 5 side.

[0039] (Regarding frame fixing plate 4) As shown in Fig. 5(b) and Fig. 6(a), the frame fixing plate 4 is fitted and fixed in the first vertical engagement groove 11 of the first vertical frame 3a. The fixing method is the same as that of the trim material 6, in which the frame fixing plate 4 is fixed to the first vertical frame 3a by finish nail fixing using a fixing tool such as a staple with a fixing member 13 such as a nail or a screw. Alternatively, instead of or in addition to the fixing member 13, the frame fixing plate 4 may be fixed by adhesive by applying an adhesive 8 to the first vertical engagement groove 11 of the first vertical frame 3a. If necessary, the frame fixing plate 4 may have a V-shaped lead groove 6c in cross section, similar to the trim material 6, and may be finished nail fixed to the first vertical frame 3a along the lead groove 6c.

[0040] The frame fixing plate 4 is fixed to the second inner wall 5 with an adhesive 8. The surface to which the adhesive 8 is applied is the surface on the second inner wall 5 side, i.e., the surface 4a of the frame fixing plate that is flush with the adjacent trim. If the adhesive 8 is applied to the frame fixing plate 4 side or the trim 6 side rather than to the second inner wall 5 side, when the frame 3 is attached and pressed into the sash frame 9a, there is a possibility that the adhesive 8 will overflow onto the interior side, and therefore it is preferable to apply the adhesive 8 to the second inner wall 5 side.

[0041] The width of the frame fixing plate 4 fixed to the first vertical engagement groove 11 is a length that is flush with the adjacent trim material 6 from the groove surface of the first vertical engagement groove 11. The depth is the same as the depth of the first vertical engagement groove 11. The height is shorter than the height of the first vertical frame 3a or the trim material 6 by the height of the first horizontal engagement groove 11 and the second horizontal engagement groove 11. After the frame fixing plate 4 is fixed to the first vertical frame 3a, the frame 3 is assembled and the frame 3 is attached to the sash frame 9a of the sash 9. Even if the first vertical frame 3a has the first vertical engagement groove 11, by providing the frame fixing plate 4, it is not necessary to prepare a new vertical frame dedicated to the recessed corner portion where the engagement groove 11 is not provided, and it is possible to attach it to the second inner wall 5 perpendicular to the first inner wall 7 with a normal vertical frame provided with the engagement groove 11 as in the general portion. Therefore, the frame 3 can be used for the opening 2 in a location other than the vicinity of the recessed corner 1, which can reduce costs and improve workability.

[0042] In this embodiment, the frame fixing plate 4 and the trim material 6 are separate structures, but as shown in Fig. 4(b), a frame trim structure 200 may be used in which the frame fixing plate 4 and the trim material 6 are integrally molded into a frame fixing trim member 17. By using the frame fixing trim member 17, it is no longer necessary to adjust the frame fixing plate 4 and the trim material 6 to be flush with the second inner wall 5 at the construction site, etc., and work efficiency can be improved.

[0043] (About the construction method) A method for constructing the picture frame edge structure 100 will be described. First, a framework A such as a C-shaped steel is constructed as the framework of the building, and then the heat insulating material B and sashes 9 are installed. After that, a first interior base material C1 and a second interior base material C2, which are the bases for the second interior wall 5, are constructed, and the second interior wall 5 is attached to the second interior base material C2. The method of attachment may be by fixing members such as screws, bolts, nails, or screws, or by gluing, and the fixing method is not limited.

[0044] 6(a), the frame fixing plate 4 is fixed to the first vertical engagement groove 11 on the second inner wall side surface 12a of the first vertical frame by finish nail fixing using a stable or the like so as to have a constant pitch, or by finish nail fixing and adhesive 8 or the like in addition to the finish nail fixing. Similarly to the frame fixing plate 4, the parting material 6 is also fixed to the second inner wall side surface 12a of the first vertical frame adjacent to the frame fixing plate 4 by finish nail fixing using a stable or the like so as to have a constant pitch, or by finish nail fixing and adhesive 8 or the like in addition to the finish nail fixing. After that, the sealing member 6f is attached to the small end surface 6e of the upper and lower ends of the parting material 6.

[0045] By fixing the trim 6 and the frame fixing plate 4 to the first vertical frame 3a before attaching the frame 3, the trim 6 and the frame fixing plate 4 are not fixed by driving nails from the frame 3 side, so the nail heads do not appear on the indoor side of the frame 3. In addition, the adhesive 8 for fixing to the second inner wall 5 does not protrude to the indoor side, so the design can be improved. In addition, by fixing the trim 6 and the frame fixing plate 4 to the first vertical frame 3a first, if the trim 6 and the frame fixing plate 4 are fitted into the gap formed between the second inner wall 5 and the first vertical frame 3a later, there is a possibility that the trim 6 and the frame fixing plate 4 will not fit into the gap, and in that case, the trim 6 and the frame fixing plate 4 will need to be shaved down to the millimeter on site to correct the problem, which is cumbersome, so this can be avoided.

[0046] After that, the frame 3 is framed. The first horizontal frame 3c and the second horizontal frame 3d located at the top and bottom, and the first vertical frame 3a and the second vertical frame 3b located at the left and right are joined to frame the frame. At this time, auxiliary members for joining, such as pilot holes for fasteners such as screws or dowels, may be used to frame the frame. The upper and lower first horizontal frames 3c and the second horizontal frames 3d and the left and right first vertical frames 3a and the second vertical frames 3b may be joined using fixing members such as screws in addition to auxiliary members such as dowels, or instead of this, or in addition to the fixing members, they may be joined using adhesive 8 or the like, and the fixing method is not limited. In addition, the frame 3 may not be framed after the trim material 6 and the frame fixing plate 4 are fixed to the first vertical frame 3a, and the trim material 6 and the frame fixing plate 4 may be fixed to the first vertical frame 3a after framing the frame 3.

[0047] After assembling the frame 3, an airtight material 14 is attached to the first vertical frame 3a. By attaching the airtight material 14, it is possible to increase the airtightness of the gap between the first vertical frame 3a and the sash 9. After that, the frame 3 is fitted from the indoor side so that the trim material 6 and the frame fixing plate 4 are aligned with the second inner wall 5, and both the left and right sides of the frame 3 are attached to the sash frame 9a from the indoor side using fixing members 13 such as screws. Since the adhesive 8 has been applied to the second inner wall 5 in advance, the first vertical frame 3a can be adhesively fixed to the second inner wall 5 at the same time as fitting the frame 3.

[0048] Thereafter, the second inner wall 5 is cross-processed. The cross-processing is performed up to the edge of the trim material 6 of the second inner wall 5. Then, after the second inner wall 5 is cross-processed, a sealing process is performed between the cross-processing and the trim material 6, and the first inner wall 7 is attached to an interior base material (not shown) to complete the construction.

[0049] <First feature> a frame trim structure at an inside corner on the indoor side, the inside corner being formed from a first inner wall having an opening and positioned on the indoor side, and a second inner wall perpendicular to the first inner wall and positioned on the indoor side, the opening being provided at the side end on the front corner side of the first inner wall, the second inner wall, and a first vertical frame extending vertically on the inside corner side of the frames positioned around the periphery of the opening, a first vertical engagement groove being provided in the longitudinal direction on the surface of the first vertical frame on the second inner wall side, a frame fixing plate that is fitted into and fixed to the first vertical engagement groove, and a trim material that is fixed to the first vertical frame adjacent to the indoor side of the frame fixing plate, the frame fixing plate and the trim material being fixed to the first vertical frame so as to be flush with each other, and the flush surfaces of the frame fixing plate and the trim material are fixed to the second inner wall,

[0050] This feature allows the second inner wall and the frame to be dry-cut, and furthermore, by fitting and fixing a frame fixing plate into the first vertical engagement groove provided in the longitudinal direction on the surface of the first vertical frame facing the inside corner, even a frame used in general areas can be used in the inside corner area.

[0051] <Second feature> This is a frame trim structure described in the first feature, characterized in that a step is provided between the indoor side surface of the trim material and the indoor side surface of the first vertical frame.

[0052] Due to this feature, a step is provided between the trim material and the first vertical frame, which has the effect of making the gap between the trim material and the first vertical frame not look like a crack.

[0053] <Third feature> This is a frame edge structure described in the first or second feature, characterized in that the center of the surface of the trim material on the second inner wall side has a lead groove in the longitudinal direction.

[0054] Due to this feature, the center of the surface that contacts the second inner wall of the trim has a lead groove in the longitudinal direction, and nails can be driven into the first vertical frame along the lead groove, so that nails can be driven into the first vertical frame from the center line of the trim, and the groove shape has the effect of making the nail less likely to slip when driven.

[0055] <Fourth feature> This is a construction method for a frame trim structure as described in the first to third features, characterized in that the construction method for a frame trim structure includes, in order, a step of constructing the second inner wall, a step of fixing the trim material and the frame fixing plate to the first vertical frame, and a step of installing and constructing the frame so that the trim material and the frame fixing plate fixed to the first vertical frame are adhesively fixed to the second inner wall.

[0056] Due to this feature, rather than installing the trim last, the trim is fixed to the first vertical frame first, which has the effect of eliminating the risk of the trim not being able to fit into the gap formed by the second inner wall, the frame fixing plate, and the first vertical frame.
