Here, the existing vertical frames 24d, 25c and the existing upper frames 24a, 25a are members that have been installed in the existing fittings before the remodeling of the remodeled fittings 10, and the vertical and horizontal facing surfaces are arranged substantially flush. There is.

For this reason, the renovated fittings 10 includes a water stop material 52 between the new vertical member 37 and the existing vertical frame 24d, and a water stop material 48 between the new upper frame 26a (cover material 28) and the existing upper frame 24a. are continuous, forming vertical and horizontal water stop lines. Furthermore, the renovated fittings 10 includes a water stop material 78 between the new vertical member 37 and the existing vertical frame 25c, and a water stop material 75 between the new upper frame 27a (cover material 56) and the existing upper frame 25a. are continuous, forming vertical and horizontal water stop lines. As a result, in the renovated fittings 10, the water-stopping performance of the existing mullion 22 and its surrounding area on the outdoor side is further improved.

Furthermore, the renovated fittings 10 employs a configuration in which the water stop materials 52, 78 are held with respect to the existing vertical frames 24d, 25c via the cover materials 36, 64. For this reason, the renovated fittings 10 allows the relative connection position between the newly installed vertical frames 24d, 25c and the cover materials 36, 64 in the prospective direction to be easily adjusted during construction; 78 can ensure a water-stop structure. That is, since the newly installed vertical frames 24d and 25c serve as supports for the newly installed shoji 18 to 20, high accuracy is required in the mounting position in the projected direction, but this makes it easy to adjust the position. On the other hand, since the cover materials 36 and 64 do not require position adjustment with respect to the existing vertical frames 24d and 25c, the water stop materials 52 and 78 can be installed reliably. The renovated fittings 10 has a structure in which the water stop materials 52, 78 are held directly between the newly installed vertical frames 24d, 25c and the existing vertical frames 24d, 25c without using the cover materials 36, 64 (attachment materials 63). You can also use it as

Next, a more specific configuration and operation and effect of the existing mullion 22 and the indoor side portion of the surrounding area will be explained.

As shown in FIG. 4, the renovated fittings 10 includes frames 84 and 85 that cover the existing mullion 22, the existing vertical frames 24d and 25c, and the cover materials 36 and 48 from the indoor side. The picture frames 84 and 85 are extruded resin members each having a substantially L-shaped cross section, and are made of polyvinyl chloride (PVC), for example.

The frame 84 includes a mounting portion 84a extending in the Z direction and a protruding piece 84b projecting toward the existing mullion 22 in the X direction from the indoor end of the mounting portion 84a. The attachment portion 84a is attached using screws 86 to the resin angle 44 attached to the indoor end of the vertical frame 26d. The protruding piece 84b is arranged closer to the indoor side than the indoor side finding surface 22d of the existing mullion 22 in the Y direction, and protrudes to a position where it overlaps with the existing mullion 22 in the X direction. The tip of the protruding piece 84b is fixed to the base material 88 using a screw 87.

In the configuration example shown in FIG. 4, on the indoor side of the existing mullion 22, there are mullion bases 90a and 90b that have a substantially U-shaped cross section and are arranged approximately symmetrically to each other, and mullion bases 90a and 90b installed on the indoor side mullion base 90b A mullion cover 91 is provided. The mullion bases 90a, 90b and the mullion cover 91 are, for example, extruded aluminum alloy members. The mullion cover 91 is also fixed with screws 92 to the angle portions 24d2, 25c3 that protrude from the indoor facing surfaces of the existing vertical frames 24d, 25c. The base material 88 is made of wood, for example, and is fixed to the mullion cover 91 using screws 93, thereby being supported by the existing mullion 22.

The frame 85 may have a laterally symmetrical structure with the frame 84 described above. That is, the picture frame 85 has a mounting portion 85a that is attached to the resin angle 72 of the vertical frame 27c with screws 86, and a protruding piece 85b that protrudes toward the indoor side of the existing mullion 22 and is fixed to the base material 88 with screws 87. .

As shown in FIG. 4, the protruding pieces 84b and 85b of the left and right picture frames 84 and 85 protrude from the indoor side finding surface 22d of the existing mullion 22 so as to face each other on the indoor side. At this time, the protruding pieces 84b and 85b have a plurality of break-off grooves 84c and 85c arranged in the protruding direction on their respective back surfaces (outdoor side finding surfaces), so that the protruding length can be easily adjusted. This allows the tips of the protruding pieces 84b and 85b to be brought as close as possible to each other.

As a result, in the renovated fittings 10, the existing metal mullion 22, existing vertical frames 24d, 25c, cover materials 36, 48, etc. are covered from the indoor side by the resin frames 84, 85, and the exterior quality is high. Provides insulation. Furthermore, by providing the frame frames 84 and 85 with break-off grooves 84c and 85c, the gap G between them can be easily controlled regardless of the dimension (X-direction dimension) of the existing mullion 22.

However, although the tips of the protruding pieces 84b and 85b can be brought close to each other, it is difficult to completely eliminate the gap G. Therefore, the renovated fittings 10 of this embodiment may further include a batten 94 as a gap hiding member that hides the gap G from the indoor side. The batten 94 is, for example, a thin resin plate, made of the same material and color as the frames 84 and 85, and extends in the height direction (Y direction) of the frames 84 and 85. The battens 94 are fixed to the indoor surfaces of the protruding pieces 84b, 85b with double-sided tape, adhesive, or the like while straddling the gap G. By providing the battens 94, the renovated fittings 10 can hide the gap G between the protruding pieces 84b and 85b of the left and right picture frames 84 and 85, further improving the appearance quality.

As a gap hiding member for hiding the gap G, a sheet-like member 96 shown in FIG. 5 may be provided instead of the batten 94. The sheet-like member 96 is, for example, a thin resin laminate sheet, and can be prepared in many colors and materials. The sheet-like member 96 can straddle the gap G and cover substantially the entire indoor surface from the attachment parts 84a, 85a to the protruding pieces 84b, 85b. The sheet-like member 96 may cover only the indoor surfaces of the protruding pieces 84b and 85b. Since the sheet-like member 96 does not have a step like the batten 94, the appearance quality of the renovated fittings 10 can be further improved. However, it takes time and effort to attach the sheet-like member 96 over a large area while preventing wrinkles and lifting. In this respect, the batten 94 does not cause wrinkles or lifting unlike the sheet-like member 96, so it has the advantage of high construction efficiency.

As the gap hiding member for hiding the gap G, a parting member 98 shown in FIG. 6 may be provided instead of the battens 94 or the sheet-like member 96. The parting material 98 is, for example, a block-shaped decorative material made of wood or resin. In the configuration example shown in FIG. 6, the gap G between the left and right protruding pieces 84b and 85b is set larger than in the configuration example shown in FIGS. 4 and 5. The parting member 98 is interposed in this large gap G and separates the protruding pieces 84b and 85b. The parting member 98 is fixed to the mullion cover 91 using, for example, a screw similar to the screw 93 in FIG. 4, double-sided tape, adhesive, or the like. The parting member 98 is sealed with a sealing material 100a between the tip of the protruding piece 84b and one prospective surface, and by sealing with the sealing material 100b between the tip of the protruding piece 85b and the other prospective surface. Gap G can be completely closed.

As a gap concealing member that hides the gap G, a configuration may be provided in which a parting member 102 shown in FIG. 7 is provided instead of the parting member 98. The parting member 102 is, for example, an extruded resin member. The parting member 102 is interposed in a large gap G between the protruding pieces 84b and 85b, and separates the protruding pieces 84b and 85b. The parting member 102 is formed of, for example, a rectangular tubular member having a pair of hollow portions, and has plate pieces 102a and 102b protruding toward the outdoor side from the left and right ends of the outdoor side facing surface. The parting material 102 is used in place of the mullion cover 91 shown in FIG. 4, and the plate pieces 102a and 102b are fixed to the existing vertical frames 24d and 25c and the mullion base 90b with screws 92. In the parting material 102, like the parting material 98, the spaces between the tips of the protruding pieces 84b, 85b and each prospective surface are sealed with sealing materials 100a, 100b.

Similar to the battens 94, the parting members 98 and 102 do not wrinkle or lift like the sheet-like member 96, so they have the advantage of high construction efficiency. In addition, the parting members 98 and 102 are formed of wood, resin, or the like, so that high appearance quality and heat insulation properties can be obtained.

Next, one procedure of the construction method for the renovated fittings 10 will be explained with reference to the flowchart shown in FIG.

First, in step S1 in FIG. 8, among the existing fittings attached to the frame 12, the existing mullion 22 and the existing frames 24 and 25 are left, and the existing shoji is removed.

In step S2, the cover materials 28, 36, 56, 64 and the attachment materials 26b1, 27b1, 63 are connected to the remaining existing frames 24, 25. Here, the cover materials 28, 36, 56, 64 and the attachment materials 26b1, 27b1, 63 are not frame-shaped members. Therefore, each of these materials can be easily connected to the existing frames 24 and 25 individually from the indoor side at the construction site, resulting in high construction efficiency (see FIGS. 2 to 4). At this time, water is appropriately cut off between the cover materials 28, 36, 56, 64 and the existing upper frames 24a, 25a and the existing vertical frames 24c, 24d, 25c, 25d with water stop materials 48, 52, 75, 78. Ru.

In step S3, the newly installed frames 26, 27 that constitute the newly installed window frame 16 are connected to the cover materials 28, 36, 56, 64 and the attachment materials 26b1, 27b1, 63. As shown in FIGS. 2 to 4, the cover materials 28, 36, 56, and 64 all have indoor side finding surfaces 28b1, 36d, 56b1, and 64d, new upper frames 26a, 27a, and vertical frames 26c, 26d, and 27c. , 27d, and the water stop materials 49, 53, 76, 79 are appropriately held here. Therefore, the new frames 26, 27, which have been framed in advance at a factory or the like, can be easily attached to the existing frames 24, 25 from the indoor side, further improving construction efficiency. In addition, the newly installed lower frames 26b, 27b can be installed by first inserting them into the inside of the frame of the attachment materials 26b1, 27b1 with a Kendon when attaching the new frames 26, 27 to the existing frames 24, 25 from the indoor side, for example. It can be easily constructed including tight materials 50 and 77.

Finally, in step S4, the left and right picture frames 84, 85 are attached to the vertical frames 26d, 27c while appropriately adjusting the lengths of the protruding pieces 84b, 85b using the break-off grooves 84c, 85c. Then, the gap G is hidden by a gap hiding member such as the batten 94, the sheet-like member 96, or the parting materials 98 and 102. As a result, the indoor facing surface 22d of the existing mullion 22 is hidden by the frames 84, 85, etc., and the construction of the renovated fitting 10 having high appearance quality and heat insulation is completed.

Although the existing mullion 22 has the outdoor finding surface 22c exposed to the outdoor side, the outdoor side has less influence on the appearance and heat insulation than the indoor side. Therefore, the renovated fittings 10 is configured so that the cover materials 36, 64 are pressed against the existing vertical frames 24d, 25c via the waterproof materials 52, 78, without daring to hide the outdoor facing surface 22c of the existing mullion 22. There is. As a result, the renovated fittings 10 can easily ensure water-stopping performance on the outdoor sides of the vertical frames 26d and 27d, regardless of the dimensions of the existing mullions 22.

Next, a refurbished fitting 10A according to a second embodiment will be described.

As shown in FIG. 9, the renovated fittings 10A according to the present embodiment have an existing mullion 22, existing vertical frames 24d and 25c, new vertical members 37, The connection structure with 65 is different. Therefore, regarding the renovated fittings 10A, the connection structure between the existing mullion 22 and the existing vertical frames 24d, 25c and the newly installed vertical members 37, 65 will be mainly described below. In addition, in the renovated fittings 10A according to the second embodiment, elements having the same or similar functions and effects as the renovated fittings 10 according to the first embodiment are given the same reference numerals, and detailed explanations will be omitted. Omitted.

First, the configuration and effects of the existing mullion 22 and its surrounding outdoor side portion in the refurbished fittings 10A will be explained.

As shown in FIG. 9, in the refurbished fittings 10A, the vertical frame 26d is connected to the existing vertical frame 24d of the first existing frame 24 via the attachment material 104, and is thereby supported by the existing mullion 22. In other words, the newly installed vertical member 37 of the renovated fitting 10A is composed of the vertical frame 26d and the attachment member 104.

In addition, the renovated fittings 10A of this embodiment is configured by a sliding window in which the first newly installed frame 26 supports the newly installed shoji 19 and 20 in a slidable manner, and the second newly installed frame 27 is a FIX window that supports the newly installed shoji 18. configured. For this reason, in the renovated fittings 10A, a fin 106 that is swallowed by the stile 20b of the newly installed shoji 20 on the indoor side is provided on the inner side of the vertical frame 26d. In addition, on the inner side of the vertical frame 27c, protruding pieces 108a and 108b, which serve as vertical frames for holding the face material 18a of the newly installed shoji 18, are provided side by side in the perspective direction. A resin attachment 43b1 is attached to the protruding piece 108b on the indoor side.

The attachment member 104 is, for example, an extruded aluminum alloy member, and has a substantially crank-shaped cross section. The attachment member 104 includes a facing plate portion 104a extending in the Z direction, and an attachment piece 104b that is formed by bending the outdoor side end of the facing plate portion 104a toward the outside of the frame, and further bending toward the outdoor side. In the attachment member 104, a mounting piece 104b is connected to the existing vertical frame 24d using screws 110. The vertical frame 26d of the refurbished fittings 10A is connected to the outer side of the frame of the prospective board portion 104a using screws 112.

In the renovated fittings 10A, the vertical frame 27c is connected to the existing vertical frame 25c of the second existing frame 25 via the attachment material 114, and is thereby supported by the existing mullion 22. In other words, the newly installed vertical member 65 of the renovated fitting 10A is composed of the vertical frame 27c and the attachment member 114.

The attachment member 114 is, for example, an extruded aluminum alloy member, and has a substantially crank-shaped cross section. The attachment member 114 includes a facing plate portion 114a extending in the Z direction, and an attachment piece 114b that bends the outdoor side end of the facing plate portion 114a toward the outside of the frame, and further bends toward the outdoor side. In the attachment member 114, a mounting piece 114b is connected to the existing vertical frame 25c using a screw 116. The vertical frame 27c of the refurbished fittings 10A is fixed to the outer side of the frame of the facing board portion 114a using screws 117.

In the renovated fittings 10A, water is cut off between the vertical frames 26d and 27c and the existing vertical frames 24d and 25c with water cutoff materials 118 and 119. The water stop material 118 is a tight material that is attached to a pocket portion 26d3 formed at a position closer to the outdoor side of the frame outer facing surface 26d2 of the vertical frame 26d. The water stop material 118 stops water between the outdoor facing surface 24d1 of the existing vertical frame 24d and the frame outside facing surface 26d2 of the vertical frame 26d. The water stop material 119 is a tight material that is attached to a pocket portion 27c3 formed at a position closer to the outdoor side of the frame outer facing surface 27c2 of the vertical frame 27c. The water stop material 119 stops water between the outdoor facing surface 25c2 of the existing vertical frame 25c and the frame outside facing surface 27c2 of the vertical frame 27c. The water-stopping materials 118 and 119 may be provided to stop water between the outdoor side finding surfaces 24d1 and 25c2 and the outdoor side or indoor side finding surfaces of the vertical frames 26d and 27c.

In the renovated fittings 10A, the connection structure and water-stopping structure between the upper frames 26a, 27a and the existing upper frames 24a, 25a are not particularly limited, but for example, the connection structure between the vertical frames 26d, 27c and the existing vertical frames 24d, 25c shown in FIG. It may be similar to the connection structure or water stop structure. In addition, in the renovated fittings 10A, the connection structure and water-stopping structure between the lower frames 26b and 27b and the existing lower frames 24b and 25b are not particularly limited, but for example, the lower frames 26b and 27b shown in FIGS. The connection structure with the lower frames 24b and 25b and the water stop structure may be the same.

In this way, the renovated fittings 10A has a high watertight performance, with water being cut off between the first new frame 26 and the first existing frame 24.

Next, the configuration and effects of the existing mullion 22 and its surrounding indoor side portion in the refurbished fittings 10A will be described.

As shown in FIG. 9, the renovated fittings 10A of this embodiment includes frames 120, 121 that cover the existing mullion 22, existing vertical frames 24d, 25c, attachment materials 104, 114, etc. from the indoor side. The picture frames 120 and 121 are extruded resin members each having a substantially L-shaped cross section, and are made of polyvinyl chloride (PVC), for example.

The frame 120 includes a mounting portion 120a extending in the Z direction, and a protruding piece 120b projecting toward the existing mullion 22 in the X direction from the indoor end of the mounting portion 120a. The attachment portion 120a is attached to the vertical frame 26d and the resin angle 44. The protruding piece 120b has a hollow portion and protrudes toward the existing mullion 22 in the X direction. The frame 121 may have a laterally symmetrical structure with the frame 120 described above. That is, the picture frame 121 has an attachment part 121a that is attached to the vertical frame 27c, and a protrusion piece 121b that protrudes toward the existing mullion 22 side.

The projecting pieces 120b, 121b of the picture frames 120, 121 have pocket portions 120c, 121c at their tips, respectively. Tight materials 122 and 123 are attached to the pocket portions 120c and 121c, respectively.

The protruding pieces 120b, 121b of the picture frames 120, 121 have a gap G between them that is larger than that in the configuration example shown in FIGS. 4 and 5, similarly to the configuration example shown in FIGS. 6 and 7. A parting member 124 is arranged in this gap G as a gap hiding member. The parting member 124 is, for example, an extruded resin member. The parting material 124 may have substantially the same structure as the parting material 102 shown in FIG. 7, except that the expected dimensions and the opening dimensions are different. Fins 124a and 124b of the parting member 124 projecting toward the outdoor side from the left and right ends of the outdoor facing surface are fixed to the mullion base 90b using screws 92. Here, since the existing vertical frames 24c and 25c of the renovated fittings 10A do not have the angle portions 24d2 and 25c3 on the interior facing surfaces, the fins 124a and 124b are directly fixed to the mullion base 90b.

The parting material 124 is sealed with a tight material 122 between the tip of the protruding piece 120b and one prospective surface, and sealed with a tight material 123 between the tip of the protruding piece 121b and the other prospective surface. Gap G can be completely closed. In the renovated fittings 10A, instead of the parting material 124, a parting material 98 serving as a decorative material shown in FIG. 6 may be used.

In this way, in the refurbished fittings 10A of this embodiment as well, the water-stopping materials 118, 119 are used to connect the facing surfaces 24d1, 25c2 of the existing vertical frames 24d, 25c where the water-stopping state for the existing mullion 22 is maintained. New vertical members 37 and 65 are being installed. As a result, even in the renovated fittings 10A, even if the dimensions of the existing mullions 22 differ depending on the construction site, water can be reliably cut off between the new vertical members 37, 65 and the existing vertical frames 24d, 25c. As a result, the renovated fittings 10A can ensure water-stopping performance in the outdoor side portion of the existing mullion 22 and its surrounding area. Also, in the renovated fittings 10A, the water-stopping materials 118 and 119 are configured to abut against the facing surfaces 24d1 and 25c2 of the existing vertical frames 24d and 25c, so that there is a gap between the existing upper frames 24a and 25a and the upper frames 26a and 27a. Vertical and horizontal water stop lines can be easily formed.

Furthermore, the refurbished fittings 10A of this embodiment is also configured to hold water stop materials 118, 119 to the existing vertical frames 24d, 25c via attachment materials 104, 114. Therefore, the connection positions of the vertical frames 24d and 25c of the refurbished fittings 10A in the prospective direction with respect to the attachment materials 104 and 114 can be easily adjusted during construction, and construction efficiency is improved.

As a gap concealing member for hiding the gap G of the renovated fittings 10A, instead of the parting member 124, a parting member 126 shown in FIG. 10 may be provided. The parting material 126 has the same or similar material and shape as the parting material 124, but has a different connection structure to the existing window frame 14. That is, in the existing window frame 14 of the configuration example shown in FIG. It has a configuration in which it is connected with a screw 23. The parting material 126 is fixed to the mullion base 90b with screws 92. Note that in FIG. 10, illustration of the existing mullion 22 is omitted, and the same applies to FIGS. 11 and 12.

As a gap concealing member for hiding the gap G of the refurbished fittings 10A, instead of the parting member 124, a parting member 128 shown in FIG. 11 may be provided. The material of the parting material 128 is the same as or similar to that of the parting material 124, but the facing dimension is larger than that of the parting material 124. That is, in the existing window frame 14 shown in FIG. 9, the dimension of the mullion base 90b is 40 mm, whereas in the existing window frame 14 shown in FIG. 11, it is 70 mm. Therefore, the parting material 128 has a larger dimension than the parting material 124.

As a gap concealing member for hiding the gap G of the renovated fittings 10A, instead of the parting material 124, a parting material 130 shown in FIG. 12 may be provided. The parting material 130 is the same or similar to the parting material 124 in material and shape, but differs in connection structure to the existing window frame 14. That is, the existing window frame 14 of the configuration example shown in FIG. 12 has angle portions 24d2, 25c3 similar to the configuration example shown in FIG. 4 on the indoor side of the existing vertical frames 24d, 25c. The parting member 130 is directly fixed to these angle portions 24d2 and 25c3 with screws 92.

As described above, the estimated dimensions and estimated dimensions of the existing mullion 22 usually differ depending on the construction site. FIG. 9 illustrates a configuration in which the expected dimension of the existing mullion 22 is 70 mm and the projected dimension of the existing mullion 22, and the projected dimension of the mullion base 90b is 40 m in FIG. FIG. 10 illustrates a configuration in which the estimated size of the existing mullion 22 is 60 mm and the estimated size of the existing mullion 22 is 40 mm. FIG. 11 illustrates a configuration in which the expected dimension of the existing mullion 22 is 60 mm and the estimated dimension of the existing mullion 22 is 70 mm. FIG. 12 illustrates a configuration in which the expected dimension of the existing mullion 22 is 70 mm, and the distance between the angle portions 24d2 and 25c3 in FIG. 12 is 50 mm. On the other hand, in FIGS. 4 to 7, the configuration in which the expected size of the existing mullion 22 is 70 mm and the expected size of the existing mullion 22 is 40 mm is illustrated, but the renovated fittings 10 according to the first embodiment described above also have the following configurations: Needless to say, it is possible to flexibly accommodate existing mullions 22 of various sizes like the renovated fittings 10A according to the second embodiment.

Next, one procedure of the method for constructing the renovated fittings 10A will be described with reference to the flowchart shown in FIG. 13.

Here, the installation procedure of the vertical frames 26d and 27c to the existing mullion 22 and the existing vertical frames 24d and 25c shown in FIGS. 9 to 12 will be explained, and A description of the frames 26c and 27d will be omitted.

Since step S11 in FIG. 13 is the same or similar step to step S1 in FIG. 8, detailed explanation will be omitted. In step S12, the attachment members 104 and 114 are connected to the existing frames 24 and 25 that constitute the existing window frame 14. Similar to step S2 in FIG. 8, since the attachment materials 104 and 114 are not frame-shaped members in this step, they can be easily connected to the existing frames 24 and 25 from the indoor side individually at the construction site, thereby improving construction efficiency. is high (see Figure 9). In addition, in step S12 of this construction method, a step of connecting any one of the parting members 124, 126, and 128 to the existing mullion 22 is also executed.

In step S13, the newly installed frames 26 and 27 that constitute the newly installed window frame 16 are connected to the attachment members 104 and 114. At this time, as shown in FIG. 9, the vertical frames 26d, 27d have water stop materials 118, 119 attached to the frame outside facing surfaces 26d2, 27d2 on the outdoor facing surfaces 24d1, 25c2 of the attachment members 104, 114. come into contact with Thereby, water is cut off between the vertical frames 26d and 27d and the existing vertical frames 24d and 25c.

Finally, in step S14, the left and right picture frames 120, 121 are attached to the vertical frames 26d, 27c. At this time, the gap G is hidden by one of the gap hiding members 124, 126, and 128.
