Description

Technical Field

[0001] The present invention relates to a frame modification structure in which a new frame member of a new installation frame for modification is connected to an existing frame member of an existing frame.

Background Art

[0002] When modifying a door which is a fitting, a new installation frame for modification is installed while leaving the existing frame of the existing door. At that time, a new frame member of the new installation frame is connected to the existing frame member of the existing frame, and the new frame member is held by the existing frame member. Further, regarding such a frame modification structure, conventionally, there is known a reforming method of a metal door frame in which a base member is used to connect a new door frame divided into two parts to an old door frame (see Patent Document 1).

[0003] In the conventional reforming method of the metal door frame described in Patent Document 1, the base member is pre-resistance welded to the old door frame, the external new door frame is screwed to the base member, and then the internal new door frame is screwed to the base member. Subsequently, the external new door frame and the internal new door frame of the new door frame are welded along the dividing position to be integrated. The old door frame is disposed inside the new door frame and surrounded by the new door frame.

[0004] On the other hand, conventionally, a frame has been attached to a new frame member, and the existing frame member has been surrounded by the frame and the new frame member. However, since the existing frame member is installed in buildings with various wall surfaces, the positional relationship between the frame and the wall surface of the building also varies variously. Therefore, in the frame modification structure provided with a frame, in order for the frame not to hit the wall surface of the building, processing of the frame may be required at the construction site, and ease of processing of the frame is required from the viewpoint of workability. In addition, in the frame modification structure, it is also required to ensure fire prevention performance in order to cope with a fire.

Furthermore, the frame modification structure 9 for the upper frame members (existing upper frame member 3, new upper frame member 6) and the frame modification structure 9 for the pair of vertical frame members (existing vertical frame member 5, new vertical frame member 8) are configured similarly. The frame modification structure 9 for the upper frame members and vertical frame members will be described below.

[0021] Figure 4 is a vertical cross-sectional view showing the frame modification structure 9 in the upper frame member of this embodiment, and is an enlarged view of the upper part of Figure 2. Figure 5 is a horizontal cross-sectional view showing the frame modification structure 9 in the vertical frame member of this embodiment, and is an enlarged view of one side of Figure 3 in the left-right direction S. As shown in the figure, the frame renovation structure 9 comprises existing frame members 3 and 5 of the existing frame 2 (existing upper frame member 3, existing vertical frame member 5), new frame members 6 and 8 of the new frame 1A (new upper frame member 6, new vertical frame member 8), base material 20, frame 30 and 40, closing material 50, and covering material 60. The new frame members 6 and 8, base material 20, frame 30 and 40, closing material 50, and covering material 60 extend in the longitudinal direction of the existing frame members 3 and 5 and are provided over the entire longitudinal direction of the existing frame members 3 and 5.

[0022] The newly installed frame members 6 and 8 cover and shield at least a portion of the existing frame members 3 and 5. Here, the newly installed frame members 6 and 8 are positioned from the existing frame opening 2A side of the existing frame members 3 and 5 to the outdoor side of the existing frame members 3 and 5, covering the existing frame members 3 and 5 on both the existing frame opening 2A side and the outdoor side. Furthermore, the newly installed frame members 6 and 8 are not positioned on the indoor side of the existing frame members 3 and 5, and do not cover the existing frame members 3 and 5 on the indoor side.

[0023] The existing frame members 3 and 5 each have an outdoor facing portion 3A and 5A, an indoor facing portion 3B and 5B, and a recessed portion 3C and 5C, respectively. The outdoor facing portions 3A and 5A are the outdoor surfaces located on the outdoor side of the existing frame members 3 and 5, and are positioned facing outwards. The indoor facing portions 3B and 5B are the indoor surfaces located on the indoor side of the existing frame members 3 and 5, and are positioned facing inwards. The outdoor facing portions 3A and 5A and the indoor facing portions 3B and 5B are arranged along the facing direction of the existing frame members 3 and 5.

[0024] The visible portions 3C and 5C of the existing frame members 3 and 5 are the inner circumferential surfaces located on the side of the existing frame opening 2A (the inner circumference side of the existing frame 2) of the existing frame members 3 and 5, and are located between the exterior visible portions 3A and 5A and the interior visible portions 3B and 5B. Furthermore, the visible portions 3C and 5C have stepped portions 3D and 5D located in the middle of the existing frame members 3 and 5 in the depth direction, and are formed in a bent shape that bends at the stepped portions 3D and 5D. The visible portions 3C and 5C extend in the depth direction of the existing frame members 3 and 5 while bending.

[0025] The base material 20 is positioned on the existing frame opening 2A side of the existing frame materials 3 and 5 and is arranged along the existing frame materials 3 and 5. The base material 20 also has a stepped portion 21 located in the middle of the indoor-outdoor direction T and a protruding portion 22 that extends to a position further outward than the existing frame materials 3 and 5, and is formed in a bent shape that bends at the stepped portion 21. The base material 20 extends in the indoor-outdoor direction T while bending. The base material 20 is arranged along the visible portions 3C and 5C of the existing frame materials 3 and 5, with the stepped portion 21 overlapping the stepped portions 3D and 5D of the visible portions 3C and 5C of the existing frame materials 3 and 5. In this state, the protruding portion 22 of the base material 20 protrudes outward relative to the outdoor visible portions 3A and 5A of the existing frame materials 3 and 5.

[0026] The base material 20 is a plate-shaped connecting material that connects the newly installed frame materials 6 and 8 to the existing frame materials 3 and 5. It is positioned between the existing frame materials 3 and 5 and the newly installed frame materials 6 and 8, and is attached to the existing frame materials 3 and 5 (here, the projection sections 3C and 5C) by screws 70 and 71 spaced apart in the indoor-outdoor direction T. Spacers 23 and 24 are sandwiched between the base material 20 and the projection sections 3C and 5C of the existing frame materials 3 and 5 at the outdoor and indoor sides of the stepped sections 3D and 5D of the projection sections 3C and 5C of the existing frame materials 3 and 5, respectively. The screws 70 and 71 are inserted through the insertion holes in the base material 20 and the insertion holes in the spacers 23 and 24, and screwed into the screw holes in the projection sections 3C and 5C of the existing frame materials 3 and 5. As a result, screws 70 and 71 are fixed to the protruding parts 3C and 5C of the existing frame materials 3 and 5, and the base material 20 is attached to the protruding parts 3C and 5C of the existing frame materials 3 and 5 by screws 70 and 71.

[0027] The newly installed frame members 6 and 8 each have a projection portion 6A and 8A, and an outdoor portion 6B and 8B. The projection portions 6A and 8A are the inner circumferential surfaces located on the new frame opening 1C side (the inner circumference side of the new frame 1A) of the newly installed frame members 6 and 8, and are positioned on the existing frame opening 2A side of the existing frame members 3 and 5. The outdoor portions 6B and 8B are the outdoor portions of the newly installed frame members 6 and 8, and are positioned on the outdoor side of the existing frame members 3 and 5, forming a gap 6C and 8C between them and the existing frame members 3 and 5. The newly installed frame members 6 and 8 cover the existing frame members 3 and 5 on the existing frame opening 2A side with the projection portions 6A and 8A, and cover the existing frame members 3 and 5 on the outdoor side with the outdoor portions 6B and 8B.

[0028] The projection portions 6A and 8A of the newly installed frame members 6 and 8 have groove-shaped retaining portions 6D and 8D for holding the tight material 80. The tight material 80 is attached to the retaining portions 6D and 8D of the projection portions 6A and 8A, protruding outward from the retaining portions 6D and 8D and contacting the door body 1B in the closed position. The retaining portions 6D and 8D are stepped portions formed in the projection portions 6A and 8A, and are located in the middle of the projection direction of the newly installed frame members 6 and 8 in the projection portions 6A and 8A. The projection portions 6A and 8A are formed in a bent shape that bends at the retaining portions 6D and 8D, and extend in the projection direction of the newly installed frame members 6 and 8 while bending.

[0029] The newly installed frame members 6 and 8 are attached to the base material 20 by screws 72 and 73 spaced apart in the indoor-outdoor direction T, and are connected to the existing frame members 3 and 5 via the screws 72 and 73 and the base material 20. Therefore, the screws 72 and 73 are connecting screws (connecting screws) for the newly installed frame members 6 and 8, and the newly installed frame members 6 and 8 are connected to the existing frame members 3 and 5 using the screws 72 and 73 (connecting screws).

[0030] The protruding portions 6A and 8A of the newly installed frame members 6 and 8 are placed on top of the base material 20, which includes the protruding portion 22, and the outdoor-facing portions 6B and 8B of the newly installed frame members 6 and 8 are placed on the outdoor side of the base material 20. At the outdoor and indoor sides of the holding portions 6D and 8D and the stepped portion 21 of the base material 20, screws 72 and 73 are inserted through the insertion holes of the protruding portions 6A and 8A of the newly installed frame members 6 and 8 and screwed into the screw holes of the base material 20. In this way, the screws 72 and 73 are fixed to the base material 20, and the protruding portions 6A and 8A of the newly installed frame members 6 and 8 are attached to the base material 20 by the screws 72 and 73. The protruding portions 6A and 8A of the newly installed frame members 6 and 8 are connected to the protruding portions 3C and 5C of the existing frame members 3 and 5 via the base material 20.

[0031] The outdoor-facing portions 6B and 8B of the newly installed frame members 6 and 8 have outdoor-facing visible portions 6E and 8E and mounting portions 6F and 8F. The outdoor-facing visible portions 6E and 8E are the outdoor-facing surfaces located on the outdoor side of the newly installed frame members 6 and 8, and are arranged facing outwards, continuous with the outdoor-facing ends of the visible portions 6A and 8A. The outdoor-facing visible portions 6E and 8E are arranged along the visible direction of the newly installed frame members 6 and 8, and the mounting portions 6F and 8F protrude inwards from the outdoor-facing visible portions 6E and 8E. In addition, the mounting portions 6F and 8F protrude toward the existing indoor-facing frame members 3 and 5 (in this case, the outdoor-facing visible portions 3A and 5A), and face the existing frame members 3 and 5 in the indoor-outdoor direction T.

[0032] The outdoor portions 6B and 8B of the newly installed frame members 6 and 8 are positioned further outdoors than the existing frame members 3 and 5, with a distance set back from the existing frame members 3 and 5. On the outdoor side of the existing frame members 3 and 5, the outdoor portions 6B and 8B form gaps 6C and 8C between them. The gaps 6C and 8C are formed between the mounting portions 6F and 8F of the outdoor portions 6B and 8B and the outdoor facing portions 3A and 5A of the existing frame members 3 and 5, and are located on the indoor side of the mounting portions 6F and 8F of the outdoor portions 6B and 8B, and on the outdoor side of the outdoor facing portions 3A and 5A of the existing frame members 3 and 5. The gaps 6C and 8C are open in both directions in the facing direction of the newly installed frame members 6 and 8.

[0033] The sealing material 50 is a plate-shaped steel material and is positioned from the outdoor-facing portions 6B and 8B of the new frame members 6 and 8 to the existing frame members 3 and 5, sealing the gaps 6C and 8C between the outdoor-facing portions 6B and 8B and the existing frame members 3 and 5. The sealing material 50 also protrudes inward from the outdoor-facing portions 6B and 8B toward the existing frame members 3 and 5, and contacts the outdoor-facing portions 6B and 8B with the existing frame members 3 and 5. The sealing material 50 is positioned along the gaps 6C and 8C along the entire longitudinal direction of the new frame members 6 and 8 and the existing frame members 3 and 5, sealing the gaps 6C and 8C completely. The gaps 6C and 8C are covered and closed by the sealing material 50.

[0034] The sealing material 50 is attached to the outdoor-facing portions 6B and 8B (in this case, mounting portions 6F and 8F) of the newly installed frame materials 6 and 8, and protrudes from the outdoor-facing portions 6B and 8B toward the existing frame materials 3 and 5. In addition, the sealing material 50 protrudes along the gap 6C and 8C from the mounting portions 6F and 8F of the outdoor-facing portions 6B and 8B toward the outdoor-facing visible portions 3A and 5A of the existing frame materials 3 and 5, and abuts against the outdoor-facing visible portions 3A and 5A of the existing frame materials 3 and 5.

[0035] The sealing material 50 has an elongated hole 51 extending in the indoor-outdoor direction T. The elongated hole 51 of the sealing material 50 is an elongated insertion hole through which a screw 74 is inserted, and the sealing material 50 is positioned by passing through the visible direction of the new frame materials 6 and 8 and overlapping the outdoor side portions 6B and 8B (in this case, the mounting portions 6F and 8F) of the new frame materials 6 and 8. The longitudinal direction of the elongated hole 51 is the indoor-outdoor direction T, which is the direction in which the elongated hole 51 extends (length direction), and the short direction of the elongated hole 51 is the longitudinal direction of the new frame materials 6 and 8, which is the width direction of the elongated hole 51. The longitudinal and short directions of the elongated hole 51 are perpendicular to each other. The screw 74 is inserted through the elongated hole 51 and screwed into the screw hole of the outdoor side portion 6B and 8B, and is fixed to the outdoor side portion 6B and 8B. The sealing material 50 is attached to the outdoor side parts 6B and 8B by screws 74.

[0036] The screw 74 can be positioned at any position within the elongated hole 51 of the sealing material 50 in the longitudinal direction (indoor-outdoor direction T) of the elongated hole 51. Therefore, when the sealing material 50 is moved in the indoor-outdoor direction T with the screw 74 loosened, the position of the screw 74 within the elongated hole 51 changes in the longitudinal direction of the elongated hole 51. This adjusts the position of the sealing material 50 in the indoor-outdoor direction T. By moving the sealing material 50 in the indoor-outdoor direction T, the position of the sealing material 50 in the indoor-outdoor direction T is adjusted to a position where the sealing material 50 abuts against the existing frame materials 3 and 5, and where the gaps 6C and 8C are sealed by the sealing material 50. In this state, the screw 74 is tightened to attach the sealing material 50 to the outdoor side parts 6B and 8B.

[0037] The existing frame members 3 and 5 are the existing upper frame member 3 and a pair of existing vertical frame members 5. The new frame members 6 and 8 are the new upper frame member 6 connected to the existing upper frame member 3 and a pair of new vertical frame members 8 connected to the pair of existing vertical frame members 5. The sealing members 50 are the sealing member 50 for the upper frame member and the sealing member 50 for the pair of vertical frame members. The sealing member 50 for the upper frame member is placed from the outdoor side 6B of the new upper frame member 6 to the existing upper frame member 3, sealing the gap 6C between the outdoor side 6B of the new upper frame member 6 and the existing upper frame member 3. The sealing members 50 for the pair of vertical frame members are placed from the outdoor side 8B of the pair of new vertical frame members 8 to the pair of existing vertical frame members 5, sealing the gap 8C between the outdoor side 8B of the pair of new vertical frame members 8 and the pair of existing vertical frame members 5.

[0038] The frames 30 and 40 are attached to at least one (either one or both) of the exterior portions 6B and 8B and the interior portions 6G and 8G of the newly installed frame materials 6 and 8. The interior portions 6G and 8G of the newly installed frame materials 6 and 8 are the parts located on the interior side of the newly installed frame materials 6 and 8. Here, the interior portions 6G and 8G are the parts located on the interior side of the projection portions 6A and 8A, and include the projection portions 6A and 8A and the interior end portions 6H and 8H of the newly installed frame materials 6 and 8. In addition, the frames 30 and 40 are attached to both the exterior portions 6B and 8B and the interior portions 6G and 8G of the newly installed frame materials 6 and 8. One of the two frames 30 and 40 is an outer frame 30 attached to the exterior parts 6B and 8B of the newly installed frame materials 6 and 8, and the other of the two frames 30 and 40 is an inner frame 40 attached to the interior parts 6G and 8G of the newly installed frame materials 6 and 8.

[0039] The outer frame 30 is attached to the exterior sides of the new frame members 6 and 8 (in this case, the exterior visible parts 6E and 8E) by screws 75, on the exterior side of the exterior parts 6B and 8B (in this case, the exterior visible parts 6E and 8E), and is located on the exterior side of the existing frame members 3 and 5, shielding the sealing material 50 and the existing frame members 3 and 5. The outer frame 30 is also positioned from the exterior sides of the new frame members 6 and 8 (6B and 8B) toward the wall surface 12 of the building 10, and faces the wall surface 12 of the building 10. The wall surface 12 of the building 10 is the exterior wall surface of the building 10 located on the outer perimeter side of the existing frame 2, and is provided facing outwards. The outer frame 30 covers and shields at least a portion of the exterior parts 6B and 8B of the newly installed frame members 6 and 8, the sealing material 50, and the parts of the existing frame members 3 and 5 that are exposed to the exterior (parts not shielded by the newly installed frame members 6 and 8 and the sealing material 50).

[0040] The outer frame 30 has a base 31 attached to the outdoor side portions 6B and 8B of the newly installed frame materials 6 and 8, a visible wall 32 continuous with the base 31, and a projection wall 33 continuous with the visible wall 33. The base 31 has a groove 34 attached to the outdoor side portions 6B and 8B by screws 75, a cap 35 fitted in the groove 34, and an overhanging wall 36 that extends outward from the groove 34. The groove 34 is open towards the outside and accommodates the heads of the screws 75. The cap 35 is fitted inside the groove 34 and covers and shields the inside of the groove 34 and the heads of the screws 75 on the outdoor side.

[0041] The visible wall 32 of the outer frame 30 protrudes from the overhanging wall 36 of the base 31 toward the opposite side of the new frame opening 1C and is positioned along the visible direction of the new frame members 6 and 8. The interior wall 33 protrudes from the visible wall 32 toward the interior side and is positioned along the interior direction of the new frame members 6 and 8. The interior wall 33 also protrudes from the visible wall 32 toward the wall surface 12 of the building 10 and faces the wall surface 12 of the building 10.

[0042] The outer frame 30 (in this case, the interior end of the visible wall 33) is positioned away from the exterior wall surface 12 of the building 10. As a result, a gap 81 is created between the outer frame 30 and the wall surface 12 of the building 10. At the location of the gap 81, a sealant 82 is applied in close contact with both the outer frame 30 and the wall surface 12 of the building 10, thereby sealing the gap 81.

[0043] The inner frame 40 is attached by screws 76 to the interior side portions 6G and 8G of the new frame materials 6 and 8 (in this case, the portions near the ends 6H and 8H of the projection portions 6A and 8A) on the new frame opening 1C side, and is located on the interior side of the existing frame materials 3 and 5. The inner frame 40 is also positioned from the interior side portions 6G and 8G of the new frame materials 6 and 8 toward the wall surface 13 of the building 10, and faces the wall surface 13 of the building 10. The wall surface 13 of the building 10 is the surface of the wooden frame 14 of the building 10, and is provided along the interior-exterior direction T. The wooden frame 14 is located on the interior side of the existing frame materials 3 and 5. The inner frame 40 covers and shields at least a portion of the interior side portions 6G and 8G, and the portions of the existing frame materials 3 and 5 that are exposed on the interior side (interior side facing portions 3B and 5B).

[0044] The inner frame 40 has a projection wall 41 attached to the indoor side portions 6G and 8G of the newly installed frame materials 6 and 8, a visible wall 42 continuous with the projection wall 41, and a positioning portion 43 and a shielding portion 44 provided on the projection wall 41. The positioning portion 43 is a projection (positioning piece) that protrudes from the projection wall 41 and abuts against the newly installed frame materials 6 and 8 to position the inner frame 40. The positioning portion 43 also abuts against the ends 6H and 8H of the indoor side portions 6G and 8G of the newly installed frame materials 6 and 8 from the indoor side to position the inner frame 40 in the indoor-outdoor direction T. The inner frame 40 is positioned relative to the newly installed frame materials 6 and 8 by the positioning portion 43 and is placed at the mounting position on the newly installed frame materials 6 and 8.

[0045] The inner frame 40's visible wall 41 is attached to the indoor side portions 6G and 8G of the new frame materials 6 and 8 by screws 76. In this state, the visible wall 41 is positioned along the indoor side portions 6G and 8G of the new frame materials 6 and 8, and protrudes inward from the indoor side portions 6G and 8G. The shielding portion 44 is the outdoor side portion of the visible wall 41 and covers and shields the screws 73. Screw 73 is one of the screws 72 and 73 (connecting screws) used to connect the new frame materials 6 and 8 to the existing frame materials 3 and 5, and is located on the indoor side. The indoor side portions 6G and 8G of the new frame materials 6 and 8 are attached to the base material 20 by screws 73 and connected to the existing frame materials 3 and 5.

[0046] The visible wall 42 of the inner frame 40 protrudes from the depth wall 41 toward the opposite side of the new frame opening 1C and is positioned along the visible direction of the new frame materials 6 and 8. The visible wall 42 also protrudes from the depth wall 41 toward the wall surface 13 of the building 10 and faces the wall surface 13 of the building 10. The inner frame 40 (in this case, the tip of the visible wall 42 on the wall surface 13 side) is positioned at a distance from the wall surface 13 of the building 10. As a result, a gap 83 is created between the inner frame 40 and the wall surface 13 of the building 10.

[0047] The covering material 60 is located on the interior side of the inner frame 40 and is attached to the wall surface 13 of the building 10 by screws 77. The covering material 60 also protrudes from the wall surface 13 of the building 10 and is positioned from the wall surface 13 of the building 10 to the visible wall 42 of the inner frame 40. The covering material 60 is positioned on the interior side of the gap 83 that occurs between the inner frame 40 and the wall surface 13 of the building 10, and covers and shields the gap 83 on the interior side.

[0048] The frames 30 and 40 are attached to the new frame materials 6 and 8 at the construction site of the new joinery 1. However, before attaching them to the new frame materials 6 and 8, the frames 30 and 40 are processed so that they do not come into contact with the walls 12 and 13 of the building 10. When processing the frames 30 and 40, processing tools are used to shape them so that they are separated from the walls 12 and 13 of the building 10. For example, the processing tool is a cutter, which is a cutting tool. The frames 30 and 40 are cut along their longitudinal direction using the cutter. In this way, the frames 30 and 40 are processed to remove unnecessary parts and adjust their dimensions.

[0049] Figures 6 to 8 show cross-sectional views illustrating examples of dimensional adjustments to the frames 30 and 40 in this embodiment. In Figures 6 to 8, the portions removed by processing the frames 30 and 40 are indicated by dashed lines. As shown in the diagram, the frames 30 and 40 are fabricated at the construction site and then attached to the new frame materials 6 and 8. In the inner frame 40, the visible wall 42 is fabricated, the unnecessary portion of the visible wall 42 is removed, and the dimensions of the visible wall 42 are adjusted. The dimensions of the visible wall 42 are the dimensions in the visible direction of the new frame materials 6 and 8, and are adjusted so that the visible wall 42 does not come into contact with the wall surface 13 of the building 10.

[0050] In the outer frame 30, the inner wall 33 is processed so that unnecessary parts of the inner wall 33 are removed and the dimensions of the inner wall 33 are adjusted. Alternatively, the outer wall 32 is processed so that unnecessary parts of the outer wall 32 are removed along with the inner wall 33 and the dimensions of the outer wall 32 are adjusted. The dimensions of the outer wall 32 are the dimensions of the new frame members 6 and 8 in the outer direction, and the dimensions of the inner wall 33 are the dimensions of the new frame members 6 and 8 in the inner direction.

[0051] In the exterior frame 30 shown in Figure 6, the dimensions of the projection wall 33 are adjusted so that the projection wall 33 does not come into contact with the wall surface 12 of the building 10. In the exterior frame 30 shown in Figure 7, the dimensions of the projection wall 33 are adjusted so that the projection wall 33 does not come into contact with the wall surface 15 of the building 10. The wall surface 15 of the building 10 is the exterior surface of the baseboard 16 of the exterior wall of the building 10, and is provided facing outwards. In the exterior frame 30 shown in Figure 8, the dimensions of the visible wall 32 are adjusted so that the visible wall 32 does not come into contact with the wall surface 17 of the building 10. The wall surface 17 of the building 10 is the exterior wall surface of the building 10 located on the exterior side of the existing frame materials 3 and 5, and is provided along the interior-exterior direction T.

[0052] In the frame renovation structure 9 described above, the existing frame materials 3 and 5 and the new frame materials 6 and 8 are made of steel, and are more heat-resistant and can withstand the heat of flames compared to, for example, frame materials made of aluminum alloy. In contrast, the frame frames 30 and 40 are made of aluminum alloy and can be processed relatively easily to correspond to the position or shape of the wall surfaces 12, 13, 15, and 17 of the building 10. Therefore, the frame renovation structure 9 makes it possible to ensure the fire resistance of the frame renovation structure 9 while enabling easy processing of the frame frames 30 and 40 at the construction site.

[0053] The positioning portion 43 of the inner frame 40 allows the inner frame 40 to be accurately positioned on the newly installed frame materials 6 and 8. The shielding portion 44 of the inner frame 40 hides the connecting screws 73 (connecting screws) of the newly installed frame materials 6 and 8, thereby enhancing the aesthetic appearance of the frame renovation structure 9. Even if a gap 83 occurs between the inner frame 40 and the wall surface 13 of the building 10, the covering material 60 can hide the gap 83, preventing it from being visible.

[0054] The new frame members 6 and 8 are connected to the existing frame members 3 and 5 with gaps 6C and 8C formed between the outdoor-facing parts 6B and 8B of the new frame members 6 and 8 and the existing frame members 3 and 5. Therefore, the new frame members 6 and 8 can be positioned at connection points to existing frame members 3 and 5 of various shapes without the outdoor-facing parts 6B and 8B of the new frame members 6 and 8 coming into contact with the existing frame members 3 and 5. Even if the gaps 6C and 8C formed between the outdoor-facing parts 6B and 8B of the new frame members 6 and 8 and the existing frame members 3 and 5 change due to differences in the shape of the existing frame members 3 and 5, the gaps 6C and 8C can be sealed with the sealing material 50. In the event of a fire, the sealing material 50 can block flames heading towards the gaps 6C and 8C, preventing flames from passing through the gaps 6C and 8C.

[0055] Therefore, the frame renovation structure 9 makes it possible to connect the new frame members 6 and 8 of the new frame 1A, which are common to the existing frame members 3 and 5 of the existing frame 2, which have different shapes, while ensuring the fire resistance performance of the frame renovation structure 9. In addition, the new frame members 6 and 8 can be easily connected to the existing frame members 3 and 5 of various shapes via the base material 20. Even if deformation such as twisting occurs in the existing frame members 3 and 5, the new frame members 6 and 8 can be connected to the existing frame members 3 and 5 via the base material 20.

[0056] The outer frame 30 prevents the exposure of the sealing material 50 and the existing frame members 3 and 5, thereby improving the aesthetic appearance of the frame renovation structure 9. Furthermore, by attaching the sealing material 50 to the exterior side portions 6B and 8B of the new frame members 6 and 8, the sealing material 50 can be easily held in a position to seal the gaps 6C and 8C, regardless of the shape of the existing frame members 3 and 5. By inserting the mounting screws 74 (mounting screws) for the sealing material 50 into the elongated holes 51 of the sealing material 50, the position of the sealing material 50 in the interior-exterior direction T can be adjusted, ensuring that the sealing material 50 reliably seals the gaps 6C and 8C even if the gaps 6C and 8C change. The sealing material 50 for the upper frame member and the pair of sealing materials 50 for the vertical frame members ensure the fire resistance performance of the frame renovation structure 9 in the upper frame member and the pair of vertical frame members.

[0057] In addition, depending on the dimensions of the exterior facing portions 3A and 5A of the existing frame members 3 and 5 in the facing direction, or the positions of the exterior facing portions 6B and 8B of the new frame members 6 and 8 in the facing direction of the existing frame members 3 and 5, the mounting portions 6F and 8F of the exterior facing portions 6B and 8B of the new frame members 6 and 8 and the sealing material 50 may be misaligned in the facing direction of the existing frame members 3 and 5 relative to the exterior facing portions 3A and 5A of the existing frame members 3 and 5. In this case, the sealing material 50 is brought into contact with a member of the building 10 (for example, a wall surface or structural frame), and the sealing material 50 closes the gaps 6C and 8C between the exterior facing portions 6B and 8B and the existing frame members 3 and 5 at the location on the building 10 member side. In this way, the sealing material 50 may be used to seal the gaps 6C and 8C between the exterior parts 6B and 8B and the existing frame materials 3 and 5 at locations other than the existing frame materials 3 and 5.

[0058] Positioning and shielding parts corresponding to the positioning part 43 and shielding part 44 of the inner frame 40 may be provided on the outer frame 30, and the gap 81 that occurs between the outer frame 30 and the wall surfaces 12, 15, 17 of the building 10 may be covered with a covering material 60. The wall surfaces of the building 10 are not limited to the above example and may be other wall surfaces (for example, the interior wall surfaces of the building 10). Only one of the two frames 30, 40 may be provided on the frame renovation structure 9. The sealing material 50 may be attached to the existing frame materials 3, 5 and the gaps 6C, 8C may be sealed with the sealing material 50.

[0059] Various aluminum alloys can be used for the frame materials 30 and 40, and various types of steel can be used for the existing frame materials 3 to 5, new frame materials 6 to 8, base material 20, and closing material 50. Examples of steel include carbon steel, special steel, and stainless steel.

[0060] The frame modification structure 9 may be installed at the locations of the existing lower frame member 4 and the new lower frame member 7, and implemented as a frame modification structure 9 for the lower frame members (existing lower frame member 4, new lower frame member 7). Furthermore, the frame modification structure 9 can be installed at at least one of the upper frame member, one vertical frame member, the other vertical frame member, and the lower frame member, and may be installed at any one, any multiple, or all of the upper frame member, one vertical frame member, the other vertical frame member, and the lower frame member. The joinery may be joinery other than doors (for example, windows).
