JP 2007-23565 A

The above-mentioned conventional refurbished sash is fixed by screwing a mounting screw into a plate-like portion of the existing upper frame and the existing vertical frame with the upper frame base material and the vertical frame base material. The mounting strength of the base material for the upper frame and the base material for the vertical frame is ensured by the pull-out strength of the threaded portion.
However, the thickness of the plate-shaped part described above varies depending on the manufacturer for old existing frames, and if the thickness is thin, sufficient installation strength may not be obtained. As a result, the plate-like portion may be deteriorated and sufficient attachment strength may not be obtained.
As described above, the thickness of the plate-like portion to which the base material is attached in the existing upper frame and the existing vertical frame is not stable, and there is concern about the mounting strength of the base material.
As described above, when the attachment strength of the base material is not sufficient, the attachment of the new frame may become unstable.

  In addition, since the base material is directly screw-fixed to the plate-like portions of the existing upper frame and the existing vertical frame, rainwater or the like may enter the building frame from the screwed portion.

  The object of the present invention is to ensure that the mounting strength of the base material for the upper frame and the base material for the vertical frame is always sufficient regardless of the state of the existing upper frame and the existing vertical frame, The new frame can be mounted firmly and stably without being affected by the state of the existing frame, and there is a risk that rainwater may enter the building frame from the upper frame base material and vertical frame base material mounting parts. There is no remodeling sash.

The present invention is a refurbished sash in which a new frame is attached using a base material for an upper frame and a base material for a vertical frame, and a shoji is attached to the new frame in the existing frame remaining in the opening of the building frame,

A new upper frame of the new frame is fixed and fixed to the frame mounting portion of the base material for the upper frame with screws,
The refurbished sash is characterized in that a new vertical frame of the new frame is fixed by screws to a frame mounting portion of the base material for the vertical frame.

In the present invention, the base material for the vertical frame has two finding direction support portions spaced in the indoor outside direction,
Each of the finding direction support portions can be brought into contact with the existing vertical frame to restrict the movement in the finding direction.
In this way, since the base material for the vertical frame does not move in the direction in which the existing vertical frame is found, when the shoji collides with the new vertical frame, the new vertical frame can move in the direction in which it is found or deform. Absent.

In the present invention, any one of the two finding direction support portions can be adjusted in the finding direction.
In this way, by changing the support position of one find direction support portion, the attachment orientation in the find direction of the base material for the vertical frame can be changed, so that the frame can be attached even if the angle in the find direction of the existing vertical frame is different. The newly installed vertical frame can be mounted in the correct mounting posture with the angle in the direction of finding the part as the set angle.

In the present invention, the supporting screw can be screwed into the vertical frame base material in the direction of finding, and the supporting screw can be used as a finding direction supporting part that can adjust the supporting position in the direction of finding.
If it does in this way, the attachment attitude | position of the finding direction of the base material for vertical frames can be changed by tightening and loosening a support screw, and the operation is easy.

In the present invention, the fixing screw of the base material for the vertical frame is screwed in the direction of finding the supporting screw, and the supporting screw is used as the finding direction supporting portion that can adjust the supporting position in the finding direction. it can.
If it does in this way, the attachment attitude | position of the base material for vertical frames can be changed by simple operation.

According to the present invention, the upper frame base material, the vertical frame base material existing upper frame, the existing vertical frame by inserting the insertion portion into the base material mounting hole of the existing upper frame, the intermediate inward plate of the existing vertical frame The movement in the longitudinal direction is restricted, and the intermediate inward plate is sandwiched between the support portion and the fixed part, thereby allowing the upper frame base material, the existing upper frame of the vertical frame base material, and the existing vertical frame to the indoor outside direction. Since the upper frame base material and vertical frame base material are attached to the existing upper frame and existing vertical frame by restricting the movement, the mounting strength of the upper frame base material and vertical frame base material can be adjusted to It can always be sufficient regardless of the state of the vertical frame.
Therefore, the new frame is securely and always attached in a stable manner without being affected by the state of the existing frame.

  Further, since screws are not used for mounting the upper frame base material and the vertical frame base material, there is no possibility that rainwater or the like may enter the building frame from each mounting portion.

As shown in FIGS. 1 and 2, the existing frame 3 of the existing sash remains in the opening 2 of the building housing 1.

A vertical closing member 52 is attached across the indoor side portion of the existing vertical frame 6 and the indoor side portion of the new vertical frame 43 to close the gaps between the indoor side portions.

The attachment of the base material 30 for the vertical frame will be described.
As shown in FIGS. 3 and 4, the existing vertical frame 6 includes a board 6 a that faces in the indoor exterior direction, and an indoor inward plate that faces in the direction (left-right direction) perpendicular to the indoor exterior direction provided on the board 6 a. 6b and the outdoor inward plate 6c have an inward recess 6d, and the substrate 6a has an intermediate inward plate 6e. The intermediate inward plate 6e is located in the inward recess 6d. In the above description, the inward plate is a plate facing the existing vertical frame 6 on the opposite side.
A base material attaching hole 6f is formed in the intermediate inward plate 6e.
The base material attachment holes 6f are long in the longitudinal direction of the existing vertical frame 6, short in the lateral direction, substantially slit-shaped, and a plurality of holes are formed at intervals in the longitudinal direction of the intermediate inward plate 6e.
That is, the base material 30 for the vertical frame is short and is attached to a plurality of positions in the longitudinal direction of the existing vertical frame 6, and accordingly, a plurality of the base material attachment holes 6f described above are formed accordingly.

  As shown in FIGS. 3 and 4, the vertical frame base material 30 includes an insertion portion 30a through which the base material attachment hole 6f is inserted, and the other side surface (outdoor side surface) in the indoor / outdoor direction of the intermediate inward plate 6e. A recessed portion forming portion 30c for forming a fixing recessed portion 31 with a support portion 30b in contact with the intermediate inward plate 6e and a side surface (inner side surface) of the intermediate inward plate 6e in the indoor / outdoor direction, and a frame mounting portion 30d for mounting the newly installed vertical frame 43 Have.

  The insertion portion 30a is inserted into the base material attachment hole 6f of the intermediate inward plate 6e, and the vertical frame base material 30 is provided in the inward recess 6d of the existing vertical frame 6, and the fixing component 31 is fixed to the fixing recess 31. 32, the fixing member 32 is pressed against one side surface of the intermediate inward plate 6e, and the support portion 30b is pressed against the other side surface of the intermediate inward plate 6e, thereby fixing the intermediate inward plate 6e to the fixed component 32. The vertical frame base material 30 is attached to the existing vertical frame 6.

  As a result, the vertical frame base material 30 is restricted from moving in the longitudinal direction of the existing vertical frame 6 by the insertion portion 30a, and the movement in the indoor outside direction is restricted by the support portion 30b and the fixed part 32. The attachment strength of the frame base material 30 is sufficient.

Further, even if the thickness of the intermediate inward plate 6e of the existing vertical frame 6 is thin, even if the intermediate inward plate 6e is deteriorated due to secular change, the attachment strength of the base material 30 for the vertical frame does not decrease. The mounting strength of the base material 30 for the vertical frame can always be sufficient without being influenced by the state of the existing vertical frame 6.
In addition, since no screws are used to attach the vertical frame base material 30, there is no risk that rainwater or the like will enter the building frame from the attachment portion.

An example of the specific shape of the base material 30 for vertical frames will be described with reference to FIGS.
The base material 30 for the vertical frame is a plate having a width slightly smaller than the length of the base material attachment hole 6f, and a one-side outward piece 33 that faces in a direction perpendicular to the indoor outside direction, and the one-side outward direction One side horizontal piece 34 heading to the other side (outside of the room) in the indoor outside direction continuous with the inner end portion of the piece 33 in the direction of finding, and the other side (outside of the room) end of the one side horizontal piece 34 in the room outside direction An intermediate outward piece 35 continuously extending toward the finding direction, an other lateral piece 36 continuing to the outer end portion in the finding direction of the intermediate outward piece 35 and directed toward the other side (outside of the room) in the indoor outside direction, It has the other side inward piece 37 which continues to the other side (outside side) end of the piece 36 in the indoor outside direction and faces the direction of finding.
The intermediate outward piece 35, the other lateral piece 36, and the other lateral piece 37 form a recessed portion 38 that opens inward in the direction of finding.

  The fixing component 32 is a plate having the same width as the width of the fixing recess 31 in the indoor / outdoor direction, and has hook pieces 32b continuous with both longitudinal ends of the intermediate piece 32a. It is a letter shape.

Then, as shown in FIG. 6A, the other inwardly facing piece 37 of the base material 30 for the vertical frame is inserted into the base material mounting hole 6f of the intermediate inward plate 6e of the existing vertical frame 6 and rotated in the direction of arrow a. While moving, as shown in FIG. 6B, the other side horizontal piece 36 is inserted into the base material mounting hole 6f, and the one side outward piece 33 and the other side horizontal piece 36 are in contact with the substrate 6a of the existing vertical frame 6. .
In this state, the intermediate piece 32a of the fixed component 32 is attached so as to be fitted into the fixing recess 31 as shown in FIG. 6C, thereby making strong contact with one side surface of the intermediate inward plate 6e and the intermediate outward piece 35. Then, the base material 30 for the vertical frame is attached to the existing vertical frame 6 by bringing the flange 32b into contact with the substrate 6a of the existing vertical frame 6.

  As a result, the vertical frame base material 30 is restricted in movement in the longitudinal direction of the existing vertical frame 6 by the other side horizontal piece 36, the other side inward piece 37 contacts the other side surface of the intermediate inward plate 6 e, and the fixed component 32. Is in contact with one side surface of the intermediate inward plate 6e, and the intermediate inward plate 6e is sandwiched between the two, thereby restricting the movement of the existing vertical frame 6 toward the indoor side.

  Thus, the other inwardly facing piece 37 of the vertical frame base material 30 is the aforementioned support part 30b, the other lateral piece 36 is the aforementioned insertion part 30a, and the other lateral piece 36 and the intermediate outwardly facing piece 35 are In the above-described recess forming portion 30c, the one side piece 34 is the above-described frame attachment portion 30d.

Further, as shown in FIG. 3, the other side horizontal piece 36 and the one side outwardly facing piece 33 are in contact with the substrate 6a of the existing vertical frame 6, so that the movement of the vertical frame base material 30 in the direction of finding is restricted.
This prevents the new frame 40 from moving in the finding direction (left-right direction), so that the new frame does not move in the finding direction (left-right direction) when the shoji 47 collides with the new vertical frame 43 and the like. No deformation.

  Since it is like this, the other side horizontal piece 36 (insertion part 30a) and the one side outward piece 33 of the said base material 30 for vertical frames are two finding direction support parts spaced apart in the indoor outer side direction.

  When there is a possibility that the fixing part 32 may fall off, the fixing part 32 is fixed to the existing vertical frame 6 using an adhesive tape, for example, a structural tape.

Then, the screw 46 is screwed onto the one side horizontal piece 34 from the new vertical frame 43 and the new vertical frame 43 is fixedly attached to the vertical frame base material 30.
In FIG. 2, a spacer 7 is interposed between the one side horizontal piece 34 and the new vertical frame 43.

Next, attachment of the upper frame base material 10 will be described with reference to FIGS.
The mounting of the upper frame base material 10 is the same as the mounting of the vertical frame base material 30 described above.
As shown in FIG. 7 and FIG. 8, the existing upper frame 4 includes a substrate 4a facing in the indoor exterior direction, an indoor inward plate 4b facing in the direction of finding (vertical direction) provided on the substrate 4a, and an outdoor inward plate. 4c has an inward recess 4d, and the substrate 4a has an intermediate inward plate 4e. The intermediate inward plate 4e is located in the inward recess 4d.
A base material attachment hole 4f is formed in the intermediate inward plate 4e.
The base material mounting holes 4f are long in the longitudinal direction of the existing upper frame 4, short in the lateral direction, substantially slit-shaped, and a plurality of holes are formed at intervals in the longitudinal direction of the intermediate inward plate 4e.
That is, the base material 10 for the upper frame is short and is attached to a plurality of positions in the longitudinal direction of the existing upper frame 4, and a plurality of the above-mentioned base material attachment holes 4f are formed accordingly.

Similar to the vertical frame base material 30 described above, the upper frame base material 10 has an insertion portion 10a, a support portion 10b, a recess formation portion 10c, and a frame attachment portion 10d, and the insertion portion 10a is an intermediate inward plate. The fixing recess 11 is formed in the same manner as described above by being inserted temporarily through the base material mounting hole 4f of 4e.
By attaching the fixing component 12 to the fixing recess 11 so as to be fitted, the intermediate inward plate 4 e is held between the support portion 10 b and the fixing component 12, and the upper frame base material 10 is attached to the existing upper frame 4.
Then, as shown in FIG. 1, the new upper frame 41 is fixedly attached to the upper frame base material 10 by screwing the screws 44 from the new upper frame 41 into the frame mounting portion 10 d of the upper frame base material 10.

Thus, the attachment strength of the upper frame base material 10 can be always sufficient without being influenced by the state of the existing upper frame 4.
Therefore, the new frame 40 can be securely and constantly attached without being influenced by the state of the existing frame 3.
In addition, since no screws are used to attach the upper frame base material 10, there is no possibility that rainwater will enter the building housing 1 from the attachment portion.

An example of the specific shape of the upper frame base material 10 will be described. Like the vertical frame base material 30, the upper frame base material 10 has a width slightly smaller than the length of the base material mounting hole 4f. The other-side outward piece 13 that is plate-shaped and that faces the finding direction, and the other-side lateral piece 14 that continues to the inner end of the finding direction of the other-side outward piece 13 and goes to one side (inner side) in the indoor direction, An intermediate outward piece 15 that is continuous with one side (indoor side) end of the other lateral piece 14 in the direction of the outside of the room and that faces in the direction of finding, and an outer end portion of the intermediate outward piece 15 that is in the direction of finding of the room. One side horizontal piece 16 directed to one side, and one side inward piece 17 continuous with one end (indoor side) end of the one side horizontal piece 16 in the indoor outside direction and directed in the direction of finding are provided.
The intermediate outward piece 15, the one side horizontal piece 16, and the one side inward piece 17 form a recessed portion 18 that opens inward in the inner and outer directions.

  And the one side inward piece 17 is the support part 10b, the one side horizontal piece 16 is the insertion part 10a, the one side horizontal piece 16 and the intermediate outward piece 15 are the recess forming part 10c, and the other side horizontal piece 14 is the frame attachment. Part 10d.

  Similarly to the fixing part 32 of the above-mentioned base material 30 for the vertical frame, the fixing part 12 has a substantially U shape having an intermediate piece 12a and a pair of fishing pieces 12b.

Next, a second embodiment of the vertical frame base material 30 will be described.
As shown in FIGS. 9 and 10, the base material 30 for the vertical frame is the same as that of the first embodiment described above, and the fixing component 32 is different.
The fixing part 32 has a hook shape with a holding piece 32c facing in the direction of finding and a mounting piece 32d facing in the interior and exterior direction, and a vertical groove 32e is formed in the middle of the interior and exterior direction of the attachment piece 32d with an opening at the lower end surface. It is.

Then, as shown in FIG. 10 (a), the base material for the vertical frame is inserted by inserting the insertion portion 30a of the base material 30 for the vertical frame into the hole 6f for base material attachment formed in the intermediate inward plate 6e of the existing vertical frame 6. The material 30 is provided in the inward recess 6d of the existing vertical frame 6.
In this state, the fixed component 32 is moved in the longitudinal direction of the existing vertical frame 6, the vertical groove 32e is fitted to the intermediate outward piece 35 of the vertical frame base material 30, and the presser piece 32c is fitted to the intermediate inward plate 6e. As shown in FIG. 10 (b), the fixing part 32 is attached so as to be fitted into the fixing recess 31 by contacting the side surface, and the holding piece 32 c of the fixing part 32 and the inward side of the vertical frame base material 30 are provided. The intermediate frame 6e of the existing vertical frame 6 is sandwiched between the piece 37 (support portion 30b) and the base material 30 for the vertical frame is attached to the existing vertical frame 6.
Then, the attachment piece 32d of the fixed component 32 and the frame attachment portion 30d (one side horizontal piece 34) of the base material 30 for the vertical frame are fixed with screws 32f.

Next, a third embodiment of the vertical frame base material 30 will be described.
The frame attachment portion 30d of the base material 30 for the vertical frame needs to be parallel to the correct attachment posture of the newly installed vertical frame 43. However, as shown in FIG. 3, the insertion portion 30a and the one-side outward piece 33 are provided. In the base material 30 for the vertical frame that is in contact with the substrate 6a of the existing vertical frame 6, if the angle θ in the direction in which the substrate 6a of the existing vertical frame 6 is found is different, the frame mounting portion 30d has the correct mounting posture of the new vertical frame 43. Since they are not parallel, the newly installed vertical frame 43 cannot be mounted in the correct mounting posture, and the mounting posture is inclined in the direction of finding.

That is, if the supporting positions of the two finding direction support portions are always constant, it is impossible to deal with the existing vertical frame 6 having different angles in the finding direction of the substrate 6a as described above.
Therefore, in this embodiment, the support position of one of the two find direction support portions can be adjusted, and the support position is changed according to the angle of the find direction of the substrate 6a, so that The frame 43 can be mounted in the correct mounting posture.

  As shown in FIG. 11, the supporting screw 60 is screwed to the vertical frame base material 30 in the direction of finding, and the supporting screw 60 is brought into contact with the existing vertical frame 6, and the supporting screw 60 and the insertion portion are inserted. 30a regulates the movement of the base material 30 for the vertical frame in the direction of finding.

Further, when the supporting position is changed by tightening and loosening the supporting screw 60 and moving in the direction of finding, the base material 30 for the vertical frame tilts in the direction of finding using the insertion portion 30a as a fulcrum, and the base for the vertical frame The mounting posture (mounting angle) in the direction of finding the material 30 can be adjusted.
Therefore, even if the angle θ in the direction of finding the substrate 6a of the existing vertical frame 6 is different, the angle in the direction of finding the frame attaching part 30d of the base material 30 for the vertical frame can be set to a set angle. The newly installed vertical frame 43 can be mounted with a correct mounting posture.
Moreover, the operation is simple.
For example, by setting the frame attachment portion 30d of the base material 30 for the vertical frame at a right angle to the finding direction, the new vertical frame 43 can be attached to the frame attaching portion 30d with a correct attachment posture perpendicular to the finding direction.

In FIG. 11, the other side portion of the one side horizontal piece 34 of the base material 30 for the vertical frame is bent into a fishing shape to form a recess 34 a, and a support screw 60 is screwed to the bottom of the recess 34 a. In addition, the head 60a of the supporting screw 60 is configured not to protrude inward in the direction of finding from the one side portion (frame mounting portion 30d) of the one side lateral piece 34 in the indoor / outside direction.
As a result, the support screw 60 does not interfere with the installation of the newly installed vertical frame 43.

Next, a fourth embodiment of the vertical frame base material 30 will be described.
This embodiment is the same as the second embodiment described above in that the support position of one of the two find direction support portions can be adjusted, but the find direction support that allows the support position to be adjusted. The shape of the part is different.

As shown in FIGS. 12 and 13, the one-side outward piece 33 of the base material 30 for the vertical frame is brought into contact with the substrate 6 a of the existing vertical frame 6 to form a finding direction support portion.
The insertion portion 30a (the other side horizontal piece 36) of the base material 30 for the vertical frame is separated from the substrate 6a.
A support screw 60 is screwed onto the fixed component 32, and the support screw 60 is brought into contact with the substrate 6a through a hole of the insertion portion 30a to form a finding direction support portion.

In this way, by tightening and loosening the support screw 60, the protruding length of the support screw 60 from the insertion portion 30a is changed by changing the degree of screwing, and the support position changes. The base material 30 tilts in the finding direction with the contact portion of the substrate 6a of the one side outward piece 33 as a fulcrum, and the mounting posture of the vertical frame base material 30 in the finding direction can be adjusted.
Moreover, the operation is easy.

As shown in FIGS. 12 and 13, the base material 30 for the vertical frame has two support portions 30 b separated in the longitudinal direction, and the two support portions 30 b are formed on the intermediate inward plate 6 e of the existing vertical frame 6. The two fixing recesses 31 are formed through the two base material attachment holes 6f and in contact with the other side surfaces of the intermediate inward plate 6e.
The fixed part 32 has a short box shape with an opening on one side, a screw hole 32h is formed in the bottom 32g, and a support screw 60 is screwed.
Then, the fixing parts 32 are attached so as to be fitted in the two fixing recesses 31, respectively, and the supporting screws 60 are brought into contact with the substrate 6 a of the existing vertical frame 6.
