As shown in FIGS. 1, 2 and 11, the screw bracket 12 has a fixed frame 12b projecting inward along the outer peripheral surface 11a of the new frame member 11 through the engaging portion 12d. It is attached to the new frame member 11 by engaging with the finding surface of the member 11 and screwing the mounting screw 13 to the new frame member 11 via the substrate portion 12a.

  Hereinafter, a procedure for replacing the existing fixture 100 attached to the frame B with the new fixture 1 will be described. In this replacement method, first, the existing shoji 120 is removed from the existing opening frame 110 of the existing fitting 100 to obtain the state shown in FIG. Next, as shown in FIG. 6, a cutting tool such as a cutter is applied from the outdoor side to remove the existing sealing material 7 provided between the existing opening frame 110 and the outer wall member 6. In the state where the existing sealing material 7 is removed, a gap is formed between the outer wall member 6 and the existing opening frame 110 as shown in FIG. 7, and the existing installation fixed to the outer surface of the housing B through this gap. The attachment piece 112 of the frame member 111 can be visually recognized from the outdoor side.

  Next, a cutting tool such as a cutter is inserted through the gap from which the existing sealing material 7 is removed, and the attachment pieces 112 are sequentially cut along the longitudinal direction of the existing frame member 111 as indicated by the cutting line in the figure. When the mounting piece 112 is cut over the entire circumference, the portion of the mounting piece 112 where the screw member 114 is screwed remains on the outer surface of the housing B, but the existing opening frame 110 and the housing B The fixed state is released. Moreover, the existing opening frame 110 in which the attachment piece 112 is cut from the outdoor side through the opening of the outer wall member 6 has a smaller outer dimension than the opening of the outer wall member 6. Accordingly, by removing the existing frame member 140 to expose the screw member 114 screwed to the auxiliary mounting piece 113, and loosening and removing the screw member 114 using a tool, the outer wall member 6 is removed as shown in FIG. The existing opening frame 110 can be removed from the outdoor side through the opening of the outer wall member 6 without being demolished.

  Here, in the case B after the existing opening frame 110 is removed as described above, the existing waterproof sheet 130 and the adhesive tape 131 arranged so as to be continuous from the outer surface to the outer surface of the mounting piece 112. Is also cut together with the attachment piece 112, so that the existing fixture 100 is attached such that there is a risk that water such as rainwater may enter the gap between the outer surface of the case B and the attachment piece 112 remaining on the case B. The waterproofness is impaired as compared with the state where it is damaged.

  Therefore, in this replacement method, as shown in FIG. 9 and FIG. 10, it is newly installed at a portion over the inner peripheral surface of the frame opening 2 in a state continuous with the existing waterproof sheet 130 remaining on the outer surface of the housing B. A waterproof sheet (waterproof member) 30 is provided. That is, for the lintel 4 positioned on the upper side of the frame opening 2 and the pillars 3 positioned on the left and right sides, as shown in FIG. The newly installed waterproof sheet 30 is disposed so as to overlap the outer surface of the waterproof sheet 130. The new waterproof sheet 30 and the inner peripheral surface of the frame opening 2 and the outer surface of the existing waterproof sheet 130 are attached with an adhesive tape or an adhesive to ensure water tightness. For the window base 5 located at the lower side of the frame opening 2, as shown in FIG. 10, the part extending from the outer surface of the window base 5 to the existing waterproof sheet 130 so as to cover the cut surface of the mounting piece 112. An inner waterproof sheet (waterproof member) 31 is disposed on the inner waterproof sheet 31, and a new waterproof sheet 30 is disposed so as to overlap the inner waterproof sheet 31 from the inner peripheral surface of the frame opening 2. A space between the inner waterproof sheet 31 and the outer surface of the window sill 5 and the existing waterproof sheet 130 is attached with an adhesive tape or an adhesive to ensure water tightness. Also between the newly installed waterproof sheet 30 and the inner peripheral surface of the frame opening 2 and the inner waterproof sheet 31, it is attached with an adhesive tape or an adhesive to ensure water tightness. Further, as shown in FIG. 11, the new waterproof sheet 30 is disposed at the corner of the frame opening 2 so as to cover the end of the new waterproof sheet 30, and an adhesive tape or adhesive is provided between the two. Paste with an agent.

  The new opening frame 10 is arranged from the outdoor side with respect to the frame opening 2 in which the new waterproof sheet 30 is arranged as described above. At this time, it is preferable that the packing material 40 is attached to the outer peripheral surface 11a of the new opening frame 10 in a compressed state in a flat plate shape so as to be continuous over the entire circumference. The position where the packing material 40 is attached is a portion facing the outdoor side on the outer peripheral surface of the new frame member 11 and facing the new waterproof sheet 30 when the new opening frame 10 is arranged in the frame opening 2. As the packing material 40, a material having airtightness and watertightness is suitable, and for example, a material made of foaming polyurethane can be applied. The reason why the packing material 40 is attached to the outer peripheral surface 11a of the new opening frame 10 in a compressed state is to make the outer dimension of the new opening frame 10 including the packing material 40 smaller than the inner dimension of the frame opening 2. The new opening frame 10 can be arranged in the frame opening 2 without causing the packing material 40 to peel off or be damaged. The compressed packing material 40 expands with time after being placed in the frame opening 2 and is filled in a gap between the new opening frame 10 and the inner peripheral surface of the frame opening 2. Desired airtightness and watertightness are ensured between the frame opening 2. The packing material 40 described above may be provided between the new opening frame 10 and the inner peripheral surface of the frame opening 2 after the new opening frame 10 is arranged in the frame opening 2.

  After the new opening frame 10 is arranged in the frame opening 2, as shown in FIG. 12, the portion of the new frame member 11 that is located on the inner side of the packing material 40 and the fixing portion 12b of the screw bracket 12 are provided for the frame. A spacer member 50 is disposed between the inner peripheral surface of the opening 2 and the gap is filled. The spacer member 50 has a plate thickness that defines a gap between the outer peripheral surface 11 a of the newly provided opening frame 10 and the inner peripheral surface of the frame opening 2, and has sufficient rigidity compared to the packing material 40. It is shape | molded by the member which has.

  After the spacer member 50 is disposed, the screw member 14 is screwed into the housing B from the prospective surface of each new frame member 11 so as to penetrate the packing material 40, and the spacer member 50 is fixed from the fixing portion 12 b of the screw bracket 12. If the screw member 14 is screwed into the housing B so as to penetrate, the new opening frame 10 is fixed to the housing B in a stable state, and further, a new frame member 60 is provided, and the new opening frame 10 and the outer wall member are provided. After the new sealing material 8 is filled between the new opening frame 10 and the new shoji 20 as shown in FIGS. 1 and 2, the new fitting 1 is completed.

  In the new fixture 1 attached as described above, since the fixing state between the frame B and the existing opening frame 110 is released by cutting the attachment piece 112, the existing opening frame 110 is not broken without breaking the outer wall member 6. Can be removed. Moreover, since the external dimension of the new opening frame 10 is smaller than the internal dimension of the frame opening 2 as the new fixture 1, the frame opening 2 is opened from the outdoor side through the opening of the outer wall member 6. The outer wall member 6 does not need to be demolished. Therefore, not only the replacement from the existing fixture 100 to the new fixture 1 can be performed in a short construction period, but also the existing outer wall member 6 can be used as it is, so that the construction cost associated with the replacement work can be suppressed. .

  In addition, each of the new frame members 11 is fixed from the surface to be found by the screw members 14. For this reason, even if the material of the existing opening frame 110 is a metal such as aluminum or a synthetic resin material, the existing frame member 111 is distorted or bent, or the cutting width of the mounting piece 112 is not uniform. Even so, there is no possibility of affecting the mounting strength of the new opening frame 10 to the housing B.

  Further, before the new opening frame 10 is arranged in the frame opening 2 of the housing B, the housing B is waterproofed by the new waterproof sheet 30 or the inner waterproof sheet 31, and the waterproof housing B and the new opening are provided. Since the packing material 40 is provided between the inner peripheral surface of the frame opening 2 and the outer peripheral surface 11a of the newly provided opening frame 10 between the frame 10 and the frame 10, the new fixture 1 can be secured with sufficient waterproofness. It can be attached.

  In the above-described embodiment, the method of exchanging the vertical window that is the existing fixture 100 with the vertical extension window that is the new fixture 1 is illustrated, but the existing fixture 100 and the new fixture 1 are not necessarily in the vertical direction. It is not necessary to be a glazed window, and need not be of the same type, and other types of joinery can be exchanged for other types of joinery.

  In the embodiment described above, the spacer member 50 is provided between the outer peripheral surface 11 a of the new opening frame 10 and the inner peripheral surface of the frame opening 2 after the new opening frame 10 is arranged in the frame opening 2. However, the spacer member 50 may be attached in advance to the outer peripheral surface 11 a of the new opening frame 10 so as to be adjacent to the packing material 40. When the spacer member 50 is attached in advance so as to be adjacent to the packing material 40, the spacer member 50 having a large protruding height is preceded when the new opening frame 10 is disposed in the frame opening 2. It becomes possible to prevent peeling and damage of the packing material 40 more reliably.

  Furthermore, the spacer member 50 is not necessarily limited to that of the embodiment. For example, as in the first modification shown in FIGS. 13A and 13B, a spacer bracket 150 that functions as a spacer member and a screw bracket is applied, and the newly opened opening frame 10 is adjacent to the packing material 40 in advance. It may be attached to the newly installed frame member 11. Further, as in the second modified example shown in FIGS. 14A and 14B, each of the new frame members 11 constituting the new opening frame 10 functions as a support protrusion 250 functioning as a spacer member and a screw bracket. The support fixing fin portion (fixed portion) 251 may be integrally formed. As shown in FIGS. 13A and 14A, the spacer bracket 150 of the first modification and the support protrusion 250 of the second modification are both on the outer peripheral side than the packing material 40 attached in a compressed state. Is provided so as to protrude.

  More specifically, the spacer bracket 150 of the first modified example includes a substrate portion (a fixed portion of the spacer member) 150a attached along the outer peripheral surface 11a of the new frame member 11, and an indoor end of the substrate portion 150a. And a pair of support projections 150b projecting from the outer and outer ends to the outer peripheral side, and an engaging part 150c projecting from the substantially central portion of the substrate part 150a toward the inner peripheral side. The new frame member 11 is attached to the new frame member 11 by engaging with the finding surface of the new frame member 11 via the engaging portion 150c and screwing the mounting screw 151 to the new frame member 11 via the substrate portion 150a.

  The support protrusions 250 of the second modified example protrude from the part positioned on the indoor side and the part adjacent to the packing material toward the outer peripheral side on the outer peripheral surface of the new frame member 11. The support fixing fin portion 251 protrudes from the finding surface of the support protrusion 250 protruding from the indoor side along the inner peripheral surface of the frame opening 2 toward the indoor side, and then toward the inner peripheral surface of the frame opening 2. And bent.

  Also in these 1st modification and 2nd modification, as shown to FIGS. 13-1 and 14-1, support protrusion part 150b with large protrusion height and support protrusion part 250 in the position adjacent to the packing material 40 are shown. Therefore, when the new opening frame 10 is disposed in the frame opening 2, it is possible to more reliably prevent the packing material 40 from being peeled off or damaged.

  In addition, after the new opening frame 10 is arranged in the frame opening 2, if the screw member 14 is screwed into the housing B via the substrate part 150a and the support fixing fin part 251 of the spacer bracket 150, respectively, The opening frame 10 is fixed to the frame opening 2 in a stable state.
