Description

  When renovating a window device provided in an opening of a building such as a general house or an apartment house to a new structure, the present invention is newly installed inside an existing window frame fixed to the inner periphery of the opening. It is related with improvement of the sash window frame apparatus for repair which assembles the window frame. Specifically, it is possible to realize a sash window frame device for repair that can shorten the construction time and can sufficiently maintain the airtightness and watertightness between the existing window frame and the new window frame. It is.

  2. Description of the Related Art Conventionally, window devices made by combining aluminum alloy extruded mold members have been widely used. FIG. 22 shows an example of such a window device. In the case of the illustrated structure, a pair of glass shojis 2a and 2b are built in a sliding manner inside the window frame 1. Of these, the window frame 1 is formed in a rectangular shape by an upper frame 3 constituting an upper side, a lower frame 4 constituting a lower side, and vertical frames 5 and 5 constituting left and right vertical sides. Each of the frames 3, 4, and 5 is made of an extruded material of an aluminum alloy. In addition, both the glass shojis 2a and 2b are engaged with the lower guide rails provided on the upper surface of the lower frame 4 and the guide blocks provided on the upper ends and the upper doors. By engaging with an upper guide rail provided on the frame 3, it is built inside the window frame 1 so as to be horizontally movable.

  For example, when the window device as described above becomes old, or when it is replaced with a new window device due to a problem in soundproof performance or airtightness, for the purpose of shortening the construction period, reducing the construction cost, etc. Many structures for assembling a new window frame using the old (existing) window frame 1 have been proposed. For example, Patent Documents 1 to 3 describe a structure in which each frame constituting a new window frame is individually fixed inside an existing window frame. 23 to 25 show an example of a conventional structure described in Patent Document 1 among them.

  In the case of the illustrated example, the existing window frame 6 is formed by combining the existing upper frame 7, the existing lower frame 8, and the left and right existing vertical frames 9, 9 into a rectangular frame shape on the inner periphery of the opening of the building. It is fixed in advance (at the time of building construction). On the other hand, the new window frame 10 includes a new upper frame 11, a new lower frame 12, and left and right new vertical frames 13, 13. These frames 11 to 13 are not connected to each other (in advance, rectangular frame shapes). Are not fixed to each other) and are individually fixed inside the existing window frame 6.

  Specifically, the new upper frame 11 is placed on the lower surface of the existing upper frame 7, the new lower frame 12 is placed on the upper surface of the existing lower frame 8, and the new vertical frames 13 and 13 are placed on the existing vertical frames. The inner surfaces of the frames 9 and 9 are coupled and fixed by a plurality of tapping screws. In particular, in the case of the conventional structure, each frame 11 to 13 constituting the new window frame 10 is replaced with each frame 7 constituting the existing window frame 6 in order to ensure a large opening area of the new window frame 10. Prior to fixing with respect to -9, the upper guide rail, the lower guide rail, and the like are cut and removed from the frames 7-9 at the construction site.

  In the case of the conventional structure, after assembling the new window frame 10 inside the existing window frame 6, both the lengthwise ends of the new upper frame 11 and the new vertical frames 13, 13 A wet sealing material (sealing material, caulking material) is provided at the abutting portion with the upper end portion, and the abutting portion between the lengthwise both ends of the new lower frame 12 and the lower end portions of the new vertical frames 13 and 13, respectively. ). This prevents moisture such as outside air and rainwater from entering between the existing window frame 6 and the new window frame 10 through the abutting portions, and the existing window frame 6 and the new window frame 10 Maintains airtightness and watertightness between.

  By the way, as a sealing means for maintaining the airtightness and watertightness between the existing window frame and the new window frame, each frame 11 to 13 constituting the new window frame 10 as in the case of the conventional structure described above. In addition to a structure in which a wet sealant is filled in the abutting portion between each other, a structure in which a wet sealant is filled between an existing window frame and a new window frame has been conventionally considered. However, in order to maintain the airtightness and watertightness between these existing window frames and new window frames, when using a wet sealant, the construction time is long, such as a long drying time is required. It is unavoidable. Furthermore, since a sealing work using a wet sealant requires skill, depending on the skill level of the operator, there is a possibility that the construction time becomes remarkably long or the airtightness and watertightness cannot be sufficiently maintained.

  On the other hand, in recent years, there has been an increasing demand for shortening the construction time for reasons such as reducing the time burden on the residents of the building to be repaired. For this reason, realization of the sash window frame apparatus for a repair which can be constructed in a short time and can fully maintain the airtightness and watertightness between the existing window frame and the new window frame is desired.

Japanese Patent Laid-Open No. 10-30377 JP 2001-193359 A JP 2008-308957 A

  In view of the circumstances as described above, the present invention can reduce the construction time, and can sufficiently maintain the airtightness and watertightness between the existing window frame and the new window frame. Invented to realize the above.

The repair sash window device of the present invention includes an existing window frame, a new window frame, and a sealing means, like the repair sash window frame device having the conventional structure described above.
Among these, the existing window frame is fixed to the inner periphery of the opening of the building, and includes an existing upper frame, an existing lower frame, and left and right existing vertical frames.
The new window frame is assembled inside the existing window frame, and includes a new upper frame, a new lower frame, and left and right new vertical frames.
Further, the sealing means maintains airtightness and watertightness between the new window frame and the existing window frame.

In particular, in the sash window frame device for refurbishment according to the present invention, the new window frame, the new upper frame, the new lower frame, and the new vertical frames constitute the existing window frame. The existing upper frame, the existing lower frame, and the existing vertical frames are individually fixed.
Further, the sealing means may be formed by applying one or more dry seal materials having elasticity over the entire circumference in a rectangular annular space formed between the existing window frame and the new window frame. It is configured by arranging them continuously. Furthermore, the sealing material is compressed between each of the frames at the same time as each frame constituting the new window frame is fixed to each frame constituting the existing window frame. It is supposed to exert the function of closing the gap between the two.

  When implementing the sash window frame device for repair of the present invention as described above, for example, as in the invention described in claim 2, the sealing material includes a sponge-like elastic body such as CR sponge, an elastomer, and the like. Or a seal lip made of an elastic material (including a case where it is partially used separately).

  When the present invention is carried out, for example, as described in claim 3, the lengthwise ends of the new upper frame, the upper ends of the left and right new vertical frames, and the length of the new lower frame A gap is provided between the respective end portions without causing both end portions in the vertical direction and the lower end portions of these new vertical frames to abut each other.

  Furthermore, when carrying out the present invention, for example, as described in claim 4, the width dimension (expected dimension) between the outer side surfaces (surfaces opposite to each other) of the outdoor side wall and the indoor side wall constituting the new upper frame. ), The width dimension (inside dimension) between the inner side surfaces (surfaces facing each other) of the outdoor side wall and the indoor side wall constituting the existing upper frame, and the outdoor side wall and the indoor side wall constituting each of the existing vertical frames And slightly smaller than the width dimension (inside dimension) between the inner side surfaces. Then, both end portions in the length direction of the new upper frame are respectively inserted inside the existing vertical frames.

According to the present invention configured as described above, there is provided a sash window frame device for repair, which can shorten the construction time and can sufficiently maintain the airtightness and watertightness between the existing window frame and the new window frame. realizable.
First, in the case of the present invention, as a sealing means for maintaining airtightness and watertightness between the existing window frame and the new window frame, a wet type sealing material is not used but a dry type sealing material is used. Because it is used, the drying time of the seal is unnecessary, and the construction time can be shortened.
Moreover, in the case of this invention, the operation | work which fixes each frame which comprises the said new window frame with respect to each frame which comprises the said existing window frame, and the operation | work which closes between each of these frames can be performed simultaneously. For this reason, compared with the case where the wet sealing material which needs to perform sealing work after the said new window frame is assembled | attached, construction time can be reduced significantly.
In the case of the present invention, the dry-type sealing material is compressed and sandwiched between each frame constituting the existing window frame and each frame constituting the new window frame. It is necessary to fix each frame constituting the frame to each frame constituting the existing window frame. However, even if such work considers sticking the said dry-type sealing material beforehand with respect to each frame which comprises the said existing window frame, for example using adhesive means, such as a double-sided tape. Compared to sealing work using a wet sealant, it can be performed in a sufficiently short time.

  Furthermore, in the case of the present invention, since a dry sealing material is used, skill is not required for work as in the case where a wet sealing material is used. In particular, in the case of the present invention, as described above, the dry sealing material is compressed and sandwiched between each frame constituting the existing window frame and each frame constituting the new window frame. However, it is necessary to fix each frame constituting the new window frame to each frame constituting the existing window frame. For such work, an adhesive means such as double-sided tape as described above is used. Therefore, it can be easily performed regardless of the skill level of the operator. Therefore, in the case of the present invention, the airtightness and watertightness between the existing window frame and the new window frame can be sufficiently maintained regardless of the skill level of the operator.

Furthermore, in the case of the invention described in claim 3, the workability of the assembling work of the new window frame can be improved. That is, when adopting a configuration in which the end portions of each frame constituting the new window frame are abutted with each other, when the existing window frame is deformed such as distortion, each of the new window frame is configured It becomes difficult to incorporate the frame and workability is reduced. On the other hand, in the case of the invention described in claim 3, such inconvenience can be solved. Therefore, according to the invention described in claim 3, the workability of the assembling work of the new window frame can be improved, and the construction time can be further shortened. In addition, moisture such as rain water can be guided to the upper surface of the existing lower frame through a gap provided between the both ends in the length direction of the new lower frame and the lower ends of the left and right new vertical frames. The drainage structure provided in the existing lower frame can be used as it is.
Furthermore, in the case of the invention described in claim 4, it is possible to prevent a conspicuous gap from being formed between the longitudinal ends of the new upper frame and the existing left and right vertical frames. For this reason, the designability of the sash window frame device for repair can be improved.

[Example of Embodiment]
1 to 18 show an example of an embodiment of the present invention. The feature of the repair sash window frame device of this example is that a rectangular annular space formed between the existing window frame 6a indicated by a chain line in each drawing and the new window frame 10a indicated by a solid line in each drawing. The dry seal line 32 is substantially continuously formed in the entire circumference 31 (to the extent that blowing of outside air or rain water is suppressed to a level that is practically acceptable). The basic structure, operation, and effects of the other parts are almost the same as those of the conventional structure shown in FIGS. For this reason, the overlapping description is simplified or omitted. Hereinafter, the configuration of the existing window frame 6a and the new window frame 10a constituting the repair sash window frame device of the present example, centering on the portions that have not been described previously and the portions that are different from the conventional structure. 4-8, after describing each, the characteristic part of this example is demonstrated with reference to the remaining drawings.

  The sash window frame device for repair of this example is constructed by assembling the new window frame 10a inside the existing window frame 6a. Among these, the existing window frame 6a is made of an extruded material of aluminum alloy, and the existing upper frame 7a, the existing lower frame 8a, and the left and right existing vertical frames 9a and 9a are connected by a known tapping screw. Depending on the structure, it is combined in a rectangular frame shape. Such an existing window frame 6a is fixed in advance (at the time of construction of the building) to the inner peripheral edge of the opening of the building. In the case of this example, the existing guide frame 6a is cut without removing the upper guide rails (existing upper guide rails 42a, 42b), the lower guide rails (existing lower guide rails 19a, 19b), etc. The window frame 6a is used as it is.

  The new window frame 10a includes a new upper frame 11a, a new lower frame 12a, and left and right new vertical frames 13a and 13a, each of which is made of an extruded material of an aluminum alloy. Such a new window frame 10a includes the new upper frame 11a on the lower surface of the existing upper frame 7a, the new lower frame 12a on the upper surface of the existing lower frame 8a, and the new vertical frames 13a and 13a on the upper surface of the existing lower frame 8a. Each of the existing vertical frames 9a, 9a is assembled and fixed inside the existing window frame 6a by being individually coupled and fixed to the inner side surface.

  Specifically, a plurality of upper tapping screws 15 in a state where a pair of upper abutting protrusions 14, 14 provided on the upper surface of the new upper frame 11a are abutted against the lower surface of the existing upper frame 7a, respectively. 15, the new upper frame 11 a is directly coupled and fixed to the existing upper frame 7 a. Similarly, a pair of side abutment ridges 16, 16 provided on the outer surface of each of the new vertical frames 13 a, 13 a are abutted against the inner surfaces of the existing vertical frames 9 a, 9 a, respectively. In this state, the new vertical frames 13a and 13a are directly coupled and fixed to the existing vertical frames 9a and 9a by using a plurality of side tapping screws 17 and 17, respectively.

  On the other hand, the new lower frame 12a is coupled and fixed to the existing lower frame 8a via a lower attachment 18 having a substantially U-shaped cross section. For this purpose, the lower attachment 18 is attached to the existing lower guide rail 19b on the indoor side of the pair of existing lower guide rails 19a and 19b provided on the upper surface of the existing lower frame 8a. 20 is used for fixing. Then, with the new lower frame 12a placed on the upper surface of the lower attachment 18 and the existing lower guide rail 19a on the outdoor side, the lower attachment is used by using the second and third lower tapping screws 20a and 20b. 18 and the existing lower guide rail 19a on the outdoor side.

  In the case of this example, when the lower attachment 18 is fixed to the indoor existing lower guide rail 19b, the presence of the outdoor existing lower guide rail 19a causes a decrease in workability. . Therefore, a plurality of through-holes (not shown) penetrating indoors and outdoors can be inserted into the existing lower guide rail 19a on the outdoor side so that a tool for fastening the first lower tapping screw 20 can be inserted. Is forming. In the case of this example, the new lower frame 12a and the lower guide rail 21 for the screen door are separated from each other, and the lower guide rail 21 for the screen door is compared with the existing lower guide rail 19a on the outdoor side. The second lower tapping screw 20b is used for fixing. On the other hand, the screen door upper guide rail 22 is provided integrally with the new upper frame 11a.

  In the case of this example, in the state where the new window frame 10a is assembled inside the existing window frame 6a, both ends of the new upper frame 11a in the length direction and the new frame frames 13a, 13a The upper gaps 23 are respectively provided between the both ends without abutting the upper ends with each other. Similarly, with respect to both the lengthwise ends of the new lower frame 12a and the lower ends of the new vertical frames 13a and 13a, the lower gap 24, 24 is provided. By providing such gaps 23 and 24, in the case of this example, the workability of the work of assembling the new window frame 10a (the work of fixing the frames 11a to 13a) is improved. For example, as in the case of the conventional structure shown in FIGS. 23 to 25, when the end portions of the frames 11 to 13 constituting the new window frame 10 are brought into contact with each other, distortion deformation or the like has occurred in the existing window frame 6. In such a case, it becomes difficult to incorporate these frames 11 to 13 and workability is reduced. On the other hand, in the case of this example, since such an inconvenience can be eliminated, the workability of the assembly work of the new window frame 10a can be improved, and the construction time can be shortened. Furthermore, since moisture such as rain water can be guided to the upper surface of the existing lower frame 8a through the lower gaps 24, 24, the drainage structure provided on the existing lower frame 8a can be used as it is.

Further, in the case of this example, as shown in FIG. 7, the width dimension (expected dimension) H _11a between the outer side surfaces of the outdoor side wall 25 and the indoor side wall 26 constituting the new upper frame 11a is set to the existing upper side. The width dimension (inside dimension) h _7a between the inner side surfaces of the outdoor side wall 27 and the indoor side wall 28 constituting the frame 7a, and the inner side surfaces of the outdoor side wall 29 and the indoor side wall 30 constituting the respective existing vertical frames 9a The mutual width dimension (inside dimension) is slightly smaller than h _9a (H _11a <h _7a , h _9a ). Then, the length (L _11a ) of the new upper frame 11a is made slightly larger than the inner opening width (W _6a ) of the existing window frame 6a (L _11a > W _6a ), and the new upper frame _11a Both end portions in the length direction of 11a are respectively inserted into the existing vertical frames 9a. With such a configuration, it is possible to prevent the formation of a conspicuous gap between the both ends in the length direction of the new upper frame 11a and the respective existing vertical frames 9a so as to deteriorate the appearance. The design of the sash window frame device is improved.

For example, as shown in a comparative example in FIG. 8, the prospective dimension H _11a ′ of the new upper frame 11a is larger than the inner dimensions h _7a ′ and h _9a ′ of the existing upper frame 7a and the existing vertical frames 9a. If the same (in the illustrated example, the prospective dimension H _11a ′ of the new upper frame 11a is the same as the prospective dimensions H _7a and H _{9a of} the existing upper frame 7a and each existing vertical frame 9a), the new upper frame 11a Is fixed to the existing upper frame 7a so that it can be seen from the indoor and outdoor directions between both longitudinal edges of the new upper frame 11a and the inner edges of the existing vertical frames 9a. It is necessary to provide a conspicuous gap. If such a gap is left, the design of the repair sash window frame device may be deteriorated. In addition, it is necessary to close the gap for airtight and watertight maintenance, and after fixing the new upper frame 11a to the existing upper frame 7a, it is necessary to close the gap with a sealing material, etc. become. On the other hand, in this example, it is possible to prevent such inconvenience from occurring.

  Particularly in the case of this example, in order to maintain airtightness and watertightness between the existing window frame 6a and the new window frame 10a having the above-described configuration, A dry seal line 32 is formed in a rectangular annular space 31 formed therebetween in a state of being substantially continuous over the entire circumference. In the case of this example, such a seal line 32 is formed in a portion between a pair of sliding door shojis 33a and 33b built inside the new window frame 10a in the indoor and outdoor directions.

  The seal line 32 includes a pair of longitudinal belt-like airtight pieces 34, 34, a lateral belt-like airtight piece 35, and a pair of upper corner angles, each of which corresponds to a dry-type sealing material described in the claims. The airtight piece 36, the pair of upper airtight pieces 37 (the outdoor side upper airtight piece 45 and the indoor side upper airtight piece 46), the pair of lower corner airtight pieces 38 and 38, and the lateral seal lip 39 Become. Of these, each of the airtight pieces 34 to 38 is a closed cell such as CR sponge, and the lateral seal lip 39 is made of an elastic material such as an elastomer. It should be noted that the seal lip made of elastic material and the sponge-like airtight piece can be properly used depending on the portion of use. Each figure shows the shape of each of the airtight pieces 34 to 38 in a free state. Of these, the upper airtight piece 37 is shown at the right end of FIG. 2, and the upper corner is also shown at the left end. The corner airtight pieces 36 are not shown.

  Each of the vertical belt-like airtight pieces 34, 34 is in a belt-like shape, and a side flat surface portion 40, 40 provided in an intermediate portion in the indoor / outdoor direction on the inner side surface of each of the existing vertical frames 9 a, 9 a Each is adhered by an adhesive means. Each of the longitudinal belt-like airtight pieces 34, 34 as described above fixes the new vertical frames 13a, 13a to the existing vertical frames 9a, 9a, and at the same time, the side flat surface portions 40, 40, Each of the new vertical frames 13a, 13a is compressed and sandwiched between the end edges of the side ridges 41, 41 provided in the intermediate portion in the indoor / outdoor direction on the outer side surface. Thereby, the space of the part between the inner side surface of each said existing vertical frame 9a, 9a and the outer side surface of each said new vertical frame 13a, 13a is block | closed by the indoor / outdoor direction intermediate part.

  The lateral belt-like airtight piece 35 has a belt-like shape, and both longitudinal end portions thereof are substantially continuous with the upper end portions of the vertical belt-like airtight pieces 34 and 34 (adjacently opposed or abutted). In the state, it is adhered to the lower surface of the existing upper frame 7a by an adhesive means such as a double-sided tape. More specifically, the horizontal band-shaped airtight piece 35 is formed between a pair of existing upper guide rails 42a and 42b provided in a state of being separated in the indoor / outdoor direction, among the lower surfaces of the existing upper frame 7a. It is affixed to the upper flat surface part 43 which exists in a part. The horizontal strip-like airtight piece 35 is fixed to the existing upper frame 7a at the same time as the new upper frame 11a, and at the same time indoors and outdoors in the upper flat surface 43 and the upper surface of the new upper frame 11a. Compressed and clamped between the upper edge of the upper ridge 44. As a result, the space between the lower surface of the existing upper frame 7a and the upper surface of the new upper frame 11a is blocked by the intermediate portion in the indoor / outdoor direction. For this purpose, the amount of protrusion of the upper protrusion 44 from the upper surface of the new upper frame 11a is made larger than the amount of protrusion of the upper abutting protrusions 14 and 14 provided on both sides of the upper protrusion 44. It is made slightly smaller (by an amount smaller than the thickness dimension in the free state of the transverse strip-like airtight piece 35).

  Each upper corner portion airtight piece 36 has a rectangular parallelepiped shape in a free state, and the longitudinal end portions of the longitudinal beltlike airtight pieces 34, 34 and the longitudinal end portions of the lateral beltlike airtight pieces 35. Are provided at the upper corners of the existing window frame 6a (inside the connecting portion between the existing upper frame 7a and the existing vertical frames 9a, 9a) in a state of covering the respective parts. In the case of this example, each said upper corner part airtight piece 36 is each affixed on the inner surface of the upper end part of each said existing vertical frame 9a, 9a by adhesion | attachment means, such as a double-sided tape. Each of the upper corner portion airtight pieces 36 as described above fixes the new upper frame 11a to the existing upper frame 7a, and at the same time, the inner surfaces of the upper ends of the existing vertical frames 9a and 9a and the new upper frame 11a. Compressed and sandwiched between both longitudinal end edges. As a result, the space between the upper corner of the existing window frame 6a and both ends in the length direction of the new upper frame 11a is closed by the indoor / outdoor intermediate portion. In the case of this example, the vertical belt-like airtight pieces 34, 34 and the horizontal belt-like airtight piece 35 are covered by the upper corner airtight pieces 36. The airtight pieces 34, 34 may be substantially continuous with an upper airtight piece 37, which will be described later, and the lateral band-like airtight piece 35 may be substantially continuous with each upper corner portion airtight piece 36.

Each of the upper airtight pieces 37 includes an outdoor-side upper airtight piece 45 and an indoor-side upper airtight piece 46 that are paired with each other. These outdoor side and indoor side upper airtight pieces 45, 46 cover the portions near the upper end of each of the longitudinal belt-like airtight pieces 34, 34, and each upper end surface is the lower end surface of each upper corner airtight piece 36. Are attached to the inner side surfaces of the portions of the existing vertical frames 9a, 9a near the upper ends thereof by an adhesive means such as a double-sided tape. . In addition, the outdoor side and indoor side upper airtight pieces 45, 46 are attached in this manner, and a new upper guide rail 47 provided at the center of the lower side of the new upper frame 11a in the indoor / outdoor direction is provided. It is sandwiched from both sides. Such outdoor side and indoor side upper airtight pieces 45, 46 fix the new vertical frames 13a, 13a to the existing vertical frames 9a, 9a, and at the same time, the existing vertical frames 9a, 9a, It is compressed and clamped between the inner side surface of the portion near the upper end of 9a and the outer side surface of the upper end portion of each of the new vertical frames 13a, 13a. As a result, the indoor and outdoor intermediate portions of the upper gaps 23 formed between the upper ends of the new vertical frames 13a and 13a and the longitudinal ends of the new upper frame 11a are blocked. Yes.
Each of the upper corner airtight pieces 36 and 36 and the upper airtight piece 37 may be integrated with each other with an interval for sandwiching the new upper guide rail 47 therebetween.

In the state (closely opposed or abutted), they are provided at the lower corners of the existing window frame 6a (inside the connecting portion between the existing lower frame 8a and the existing vertical frames 9a and 9a). In the case of this example, each of the lower corner portion airtight pieces 38, 38 is a double-sided tape or the like at a portion between the existing lower guide rails 19a, 19b on the upper surface of both ends in the length direction of the existing lower frame 8a. Are attached by the bonding means. Each of the lower corner portion airtight pieces 38, 38 fixes the new lower frame 12a to the existing lower frame 8a, and at the same time the upper surface of the existing lower frame 8a near the end in the length direction and the new lower frame. While being compressed and sandwiched between the bottom surface of the longitudinal end portion of the frame 12a, the longitudinal end portion of the hanging wall portion 48 formed on the bottom surface of the new lower frame 12a and each of the existing vertical frames 9a, It is compressed and sandwiched between the inner surface of the lower end of 9a. Further, each of the lower corner portion airtight pieces 38, 38 fixes each of the new vertical frames 13a, 13a to each of the existing vertical frames 9a, 9a, and at the same time, the upper surface of the end of the existing lower frame 8a in the longitudinal direction. And the new vertical frames 13a, 13a are compressed and sandwiched between the lower end surfaces (the portions including the lower end surfaces of the side protrusions 41). As a result, the space between the lower corner of the existing window frame 6a and the lower end of each of the new vertical frames 13a, 13a is closed by the intermediate portion in the indoor / outdoor direction, and the length of the new lower frame 12a. The intermediate portions in the indoor / outdoor direction of the lower gaps 24 and 24 formed between the both ends in the direction and the lower end portions of the new vertical frames 13a are closed.

  Further, the lateral seal lip 39 is provided on the lower surface of the new lower frame 12a over the entire length of the new lower frame 12a. Specifically, the base end portion is supported on the outdoor side surface of the hanging wall portion 48 provided on the lower surface of the new lower frame 12a. Such a lateral seal lip 39 is compressed simultaneously with fixing the new lower frame 12a to the existing lower frame 8a, and its tip edge is elastically contacted with the upper surface of the intermediate portion in the longitudinal direction of the existing lower frame 8a. In this state, it is disposed between the upper surface of the existing lower frame 8a and the lower surface of the new lower frame 12a. Further, both end portions in the length direction of the lateral seal lip 39 are substantially continuous (adjacently opposed or abutted) with the side surfaces of the lower corner portion airtight pieces 38, 38, respectively. As a result, the space between the upper surface of the existing lower frame 8a and the lower surface of the new lower frame 12a is blocked by the intermediate portion in the indoor / outdoor direction.

  In the case of this example, the distal end portion of the lateral seal lip 39 is inclined toward the outdoor side toward the distal end side. With such a configuration, drainage is improved. In other words, the horizontal seal lip 39 is prevented from drowning indoors by the wind blown from the outdoor side toward the indoor side, and the drainage that flows from the indoor side toward the outdoor side on the upper surface of the existing lower frame 8a. Is prevented from being blocked by the lateral seal lip 39.

With the above-described configuration, in the case of this example, the airtight pieces 34 to 38 and the lateral portions are placed in a rectangular annular space 31 formed between the existing window frame 6a and the new window frame 10a. A dry seal line 32 composed of a directional seal lip 39 is formed over the entire circumference without any gaps. Therefore, in the case of this example, such a seal line 32 maintains the airtightness and watertightness between the existing window frame 6a and the new window frame 10a.
Hereinafter, the assembly procedure of the sash window frame device for repair of the present example having the above-described configuration will be described in order with reference mainly to FIGS.

  First, as a preparation process, a pair of existing sliding door shoils (not shown) are removed from the inside of the existing window frame 6a. Next, the lower surface of the existing upper frame 7a, the upper surface of the existing lower frame 8a, and the inner side surfaces of the left and right existing vertical frames 9a and 9a constituting the existing window frame 6a are respectively degreased and cleaned. After completing such a preparation step, first, as shown in FIG. 9, a pair of longitudinal belt-like airtight pieces 34 are formed on the side flat surface portion 40 of the inner side surface of each of the existing vertical frames 9a. On the other hand, it sticks by adhesion means, such as a double-sided tape, respectively.

Particularly in the case of this example, the expected size (H _11a ) of the new upper frame 11a is made smaller than the inner size (h _9a ) of each of the existing vertical frames 9a. The fixing work can be performed as follows. First, in a state where the new upper frame 11a is inclined in the vertical direction, the new upper frame 11a is brought close to the existing upper frame 7a from below, and one end in the longitudinal direction located at the upper side is compared with the inside of one existing vertical frame 9a. Make a large entry. Then, one side surface in the length direction of the new upper frame 11a is pressed against the side surface of one upper corner portion airtight piece 36, and this one upper corner portion airtight piece 36 is greatly elastically deformed. Thereafter, the other end portion in the length direction is lifted upward until the new upper frame 11a becomes horizontal, and the side surface of the other end portion in the length direction is made to face the side surface of the other upper corner portion airtight piece 36. Next, the new upper frame 11a is moved (repeatedly) to the other upper corner corner airtight piece 36 side, and the other upper corner corner airtight piece 36 is elastically deformed. Then, after making the elastic deformation amount (crushing amount) of the one and the other upper corner portion airtight piece 36 substantially the same, the upper upper tapping screws 15, 15 are used to attach the new upper frame 11 a to the existing upper portion. It fixes with respect to the frame 7a.

  After the new upper frame 11a is fixed to the existing upper frame 7a as described above, as shown in FIGS. 13 and 14, the outdoor-side upper airtight piece 45 and the house constituting the pair of upper airtight pieces 37 are provided. The inner upper airtight piece 46 covers a portion near the upper end of each of the longitudinal belt-like airtight pieces 34 and the upper end surface of each inner upper airtight piece 46 is substantially continuous with the lower end surface of each upper corner airtight piece 36 (proximity facing). In the state of being abutted), each of the existing vertical frames 9a is adhered to the inner surface of the portion near the upper end by an adhesive means such as a double-sided tape. Next, as shown in FIGS. 15 and 16, a pair of lower corner airtight pieces 38 are made to have their respective side surfaces substantially continuous with the lower end side surfaces of the longitudinal belt-like airtight pieces 34 (adjacently facing or protruding). Applied) to the upper surfaces of both ends in the length direction of the existing lower frame 8a by adhesive means such as double-sided tape.

  Then, as shown in FIG. 17, each said new vertical frame 13a is fixed to the inner surface of each said existing vertical frame 9a using the some side part tapping screws 17 and 17. FIG. Thereby, between the side part flat surface part 40 provided in the inner surface of each said existing vertical frame 9a, and the front-end edge of the side part protrusion 41 provided in the outer surface of each said new vertical frame 13a. The vertical strip-like airtight piece 34 is compressed and sandwiched, and the inner side surface of the upper end portion of each of the existing vertical frames 9a and the outer surface of the upper end portion of each of the new vertical frames 13a, The upper airtight piece 37 (the outdoor side upper airtight piece 45 and the indoor side upper airtight piece 46) is compressed and sandwiched. Further, as shown in FIG. 18, the lower corner airtight pieces 38 are compressed and sandwiched between the upper surfaces of both ends in the length direction of the existing lower frame 8a and the lower end surfaces of the new vertical frames 13a. . This closes the indoor / outdoor intermediate portion of the space between the inner side surface of each existing vertical frame 9a and the outer side surface of each new vertical frame 13a, and the upper end of each new vertical frame 13a. And the indoor and outdoor intermediate portions of the upper gaps 23, 23 formed at a portion between both ends of the new upper frame 11 a in the length direction. Further, the space between the lower corner portion of the existing window frame 6a and the lower end portion of each new vertical frame 13a is closed. In other words, both vertical sides of the rectangular annular space 31 formed between the existing window frame 6a and the new window frame 10a are closed.

Finally, as shown in FIG. 18, the new lower frame 12a is fixed to the upper surface of the existing lower frame 8a using a plurality of lower tapping screws 20, 20a, 20b. Of course, the base end portion of the lateral seal lip 39 is supported on the hanging wall portion 48 formed on the lower surface of the new lower frame 12a before such an operation is performed. By fixing the new lower frame 12a to the existing lower frame 8a in this way, the lateral seal lip 39 is compressed, and at the same time, the tip edge thereof is brought into elastic contact with the upper surface of the existing lower frame 8a. In the state, it is disposed between the upper surface of the existing lower frame 8a and the lower surface of the new lower frame 12a. Further, both end portions in the lengthwise direction of the lateral seal lip 39 are substantially continued to the side surfaces of the respective lower corner portion airtight pieces 38 (adjacently opposed or abutted). The lower corner airtight pieces 38 are compressed and sandwiched between the upper surface of the portion of the existing lower frame 8a near both ends in the length direction and the lower surface of both ends of the new lower frame 12a in the length direction. As a result, the intermediate portion in the indoor / outdoor direction of the space between the upper surface of the existing lower frame 8a and the lower surface of the new lower frame 12a is blocked, and both end portions in the length direction of the new lower frame 12a and each of the new frames Then, the indoor and outdoor intermediate portions of the lower gaps 24, 24 formed between the lower ends of the frame 13a are closed. In other words, the lower side of the rectangular annular space 31 formed between the existing window frame 6a and the new window frame 10a is closed.
The construction of the repair sash window frame device of the present example is completed by the above-described process, and then new sliding door screens 33a and 33b are respectively built inside the new window frame 10a. In addition, in each figure, the glass panel which comprises each of these sliding door shojis 33a and 33b is abbreviate | omitted and shown.

In the case of the sash window frame device for repair of this example, which has the above-described configuration and is assembled through the above-described steps, the construction time can be shortened and the existing window frame 6a and the new window frame device can be reduced. Airtightness and watertightness between the window frame 10a can be sufficiently maintained.
First, in the case of this example, as a sealing means for maintaining airtightness and watertightness between the existing window frame 6a and the new window frame 10a, a wet seal as in the case of the above-described conventional structure is used. No material is used, and each of the airtight pieces 34 to 38 and the lateral seal lip 39, each of which is a dry seal material, are used. For this reason, the drying time of the seal becomes unnecessary, and the construction time can be shortened.

  In the case of this example, the work of fixing the frames 11a to 13a constituting the new window frame 10a to the frames 7a to 9a constituting the existing window frame 6a, and the respective frames 7a to 7a. The work of closing the space between the portions 9a and 11a to 13a can be performed simultaneously. For this reason, compared with the case where the wet sealing material which needs to perform sealing work after the said new window frame 10a is assembled | attached, construction time can be shortened significantly. In this example, the airtight pieces 34 to 38 are adhered to the frames 7a to 9a constituting the existing window frame 6a by an adhesive means such as a double-sided tape. The sticking operation can be performed in a sufficiently short time compared to the sealing operation using a wet sealant.

  Further, in the case of this example, since each of the airtight pieces 34 to 38 and the lateral seal lip 39, each of which is a dry seal material, is used, as in the case of using a wet seal material, Does not require skill. That is, in the case of this example, each of the airtight pieces 34 to 38 and the lateral seal lip 39 are made of each of the frames 7a to 9a constituting the existing window frame 6a and each of the new window frame 10a. It is necessary to fix each frame 11a-13a which comprises these new window frames 10a with respect to each frame 7a-9a which comprises the said existing window frame 6a in the state compressed and clamped between the frames 11a-13a. However, in the case of this example, since it is performed using an adhesive means such as a double-sided tape, this operation can be easily performed regardless of the skill level of the operator. Therefore, in the case of this example, the airtightness and watertightness between the existing window frame 6a and the new window frame 10a can be sufficiently maintained regardless of the skill level of the operator.

  In the case of this example, the existing upper guide rails 42a and 42b and the existing lower guide rails 19a and 19b are not cut away from the existing window frame 6a as in the case of the conventional structure described above. The window frame 6a is used as it is. For this reason, the work time for cutting and removing can be omitted, and the construction time can be shortened also from this aspect.

  In the example of the embodiment described above, the new upper frame 11a has a linear structure at both ends in the length direction. However, for example, as shown in FIG. It is also possible to use one in which only the middle part in the indoor / outdoor direction at both ends in the vertical direction protrudes toward the upper corner part airtight piece 36 rather than the other part.

  In the example of the embodiment described above, a structure in which the upper door guide rail 22 for the screen door is integrally provided as a new upper frame 11a near the lower end of the outdoor side wall 25 is shown. As shown in A), the upper guide rail 22 for the screen door may be omitted. Also, the number of new upper guide rails 47 provided on the lower surface of the new upper frame 11a is not limited. For example, as shown in FIG. The upper guide rails 47a and 47b may be provided. Further, as shown in FIG. 6C, the structures shown in FIGS.

  Furthermore, in the example of the embodiment, the structure in which a pair of existing upper guide rails 42a and 42b is provided on the lower surface of the existing upper frame 7a is shown. For example, as shown in FIG. A structure in which one existing lower guide rail 42c is provided in the present invention is also an object of the present invention. When using such an existing upper frame 7a having one existing lower guide rail 42c, the existing upper frame 7a is provided between the two upper abutting protrusions 14a and 14b provided on the upper surface of the new upper frame 11a. The upper guide rail 42c is positioned. Further, the seal line 32 (lateral belt-like airtight piece 35) may be compressed and sandwiched between the leading edge of the existing lower guide rail 42c and the upper surface of the new upper frame 11a as shown by the chain line. Then, the upper flat surface portion 43a formed between the existing lower guide rail 42c and the indoor side wall 28 is compressed and sandwiched between the indoor upper-side abutting protrusion 14b of the new upper frame 11a.
