  Hereinafter, a method for refurbishing the existing sash frame 20 according to the present embodiment and a renovated sash frame used for this will be described with reference to the drawings.

  FIG. 1 is a horizontal sectional view of a vertical frame portion existing in the left-right direction in the sash frame according to the present embodiment. In particular, reference numerals (A) to (D) in the drawing are replaced in this order. It shows that the process is carried out (the same applies to the following drawings).

  In particular, the embodiment shown in FIG. 1 shows an example in which an existing sash frame 20 exists inside the housing 10. That is, in the embodiment shown in FIG. 1, an example in which the vertical frame portion of the sash frame 20 is installed on the surface (that is, the inner surface) existing on the side where the sash 30 is fitted in the sash frame 20. Show. The procedure of the refurbishing method of the existing sash frame 20 in this embodiment will be described along the flow of FIGS.

  First, when the remodeling method of the existing sash frame 20 according to the present embodiment is performed, it is necessary to remove the existing sash frame 20 already installed in the building. Therefore, in the present embodiment, as shown in FIG. 1A, the fin portion 22 that attaches the existing sash frame 20 to the housing 10 is cut along the length direction. At this time, the cut portion (arrow P in the drawing) of the fin portion 22 is on the inner side (that is, the side where the sash 30 is present) than the fixing portion such as the screw or the nail 12 that attaches the fin portion 22 to the housing 10. It should be adjusted so that In particular, in consideration of many existing sash frames 20 that have been installed in the past, the cutting point P may cut a portion that is 5 to 10 mm away from the outside (tip side) of the fin portion 22. desirable. If the existing sash frame 20 (vertical frame) is attached to the housing 10 with screws or nails 12 or the like from the rail side (that is, the side where the sash 30 is present), the screws or nails 12 are removed. . Thereby, the coupling | bonding of the existing sash frame 20 and the housing 10 will be released.

  Next, as shown in FIG. 1B, the existing sash frame 20 is removed from the cut fin portion 22 together with the outer wall 40. At this time, the tip end side 22a of the cut fin portion 22 remains between the housing 10 and the outer wall 40. Even if the portion 22a remains, the sash frame 50 according to the present embodiment. This will not cause any trouble in the installation of the building, nor will it adversely affect the building such as leakage of rainwater. Rather, if the tip 22a of the fin portion 22 is to be removed, the outer wall 40 of the portion 22a must also be removed. As a result, after the new sash frame 50 is installed, If repair is necessary or the same outer wall material does not exist, the appearance of the building will be adversely affected. Therefore, as in the present embodiment, it is desirable that the distal end side 22a of the cut fin portion 22 remains as it is.

  FIG. 1C shows a state in which a new sash frame 50 is installed at a location where the existing sash frame 20 is removed. The new sash frame 50 installed in the present embodiment is formed such that the fin portion 51 that is in contact with the side surface of the housing 10 is shortened in the developing direction of the outer wall. This is to avoid interference with the fin portion 22a of the existing sash frame remaining in the housing 10. On the other hand, in the present embodiment, the fin portion 51 includes a first portion 52 that comes into contact with the side surface of the housing 10, a second portion 54 that is bent so as to rise from the side surface of the housing 10, and a tip side of the second portion. Is formed with a third portion 56 (that is, a shield portion) bent in a direction along the side surface of the housing 10, particularly in a direction toward the outside of the housing 10.

  Next, a state where a new sash frame 50 according to the present embodiment configured as described above is installed will be described with reference to FIG. In the new sash frame 50 according to the present embodiment, the fin portion 51 is bent in the same direction as the first portion 52, the second portion 54 bent outward from the first portion, and the second portion from the first portion. A third portion 56 is provided. Since the first portion 52 in contact with the side surface of the housing 10 is formed to have a length that does not interfere with the separated fin portion 22 a of the existing sash frame 20 remaining in the housing 10, the new sash frame 50. When installing, a certain gap is generated between the existing sash frame 20 and the separated fin portion 22a. Therefore, as shown in FIG. 1D, the gap is filled with a sealing material 42 or the like to prevent rainwater from entering from the gap. Further, in the sash frame 50 according to this embodiment, the second portion 54 in the fin portion 51 can be opposed to the outer wall 40 present on the side surface of the housing 10, and the sealing material 42 Since the space that appears due to the opposing arrangement is sufficiently filled, rainwater intrusion due to the installation of the new sash frame 50 can be reliably prevented. Furthermore, since the third portion 56 is formed in the fin portion 51 of the sash frame 50 according to this embodiment, the filled sealing material 42 can be covered by the third portion 56, Therefore, the sealing portion 42 can be made inconspicuous.

  The newly installed sash frame 50 can be fixed by driving screws or nails 12 into the housing 10 from the rail side, and can also be fixed by the sealing material 42. Therefore, it is desirable that the sealing material 42 used is a silicon-based or acrylic sealing material 42.

  According to the remodeling method of the existing sash frame 20 as described above, the removal area of the outer wall 40 existing around the existing sash frame 20 can be reduced, and thus the repair work can be easily performed. Furthermore, even if the same outer wall material does not exist, there is no problem because the sealing material 42 is used, and the presence of the second portion 54 increases the adhesion with the sealing material 42, thereby suppressing rainwater intrusion. it can. Further, since the sealing material 42 is covered with the third portion 56 so as not to stand out, the appearance is not impaired.

  Next, referring to FIG. 2, when the existing sash frame 20 exists on the side surface of the housing 10, that is, when the vertical frame portion is installed so that the sash frame 20 protrudes from the side surface of the housing 10. The procedure of the renovation method is explained.

  The existing sash frame 20 in this embodiment has a vertical frame attached to the side surface of the housing 10 at the fin portion 22. Therefore, as shown in FIG. 2 (A), the outer wall 40 on the inner side (that is, the side where the sash 30 is present) than the fixed portion where the fin portion 22 is attached to the housing 10 is placed together with the fin portion 22 and a disk grinder or the like. Cut with a tool. Thereby, like the above-mentioned embodiment, the existing sash frame 20 can be removed in the state which left the front end side 22a of the fin part 22 (FIG. 2 (B)).

  And the new sash frame 50 is installed in the part which removed the existing sash frame 20 (FIG.2 (C)). The new sash frame 50 installed here has a length that does not interfere with the separated fin portion 22a in the existing sash frame 20 remaining in the housing 10 even if the fin portion does not exist or exists temporarily. Is done. When the new sash frame 50 formed in this way is installed, a gap is generated between the end surface of the outer wall 40 generated by removing the existing sash frame 20. Therefore, the gap 42 is filled with a sealing material 42 to prevent rainwater from penetrating through the gap.

  On the other hand, the fin part is not provided in the sash frame newly installed in this Embodiment. Therefore, in order to attach the sash frame 50 to the housing 10, the side surface of the sash frame 50 is formed with a hole 53 for passing a screw, a nail 12 or the like through the inside of the side surface (FIG. 2C). .

  When the sash frame is actually attached to the housing 10, it can be held to some extent by the sealing material 42. Then, the sash frame 50 can be securely fixed to the housing 10 by a nail, a screw 12 or the like inserted into the side surface (FIG. 2D). The hole 53 formed in the side surface is preferably closed with a lid 55 or the like in order to prevent rainwater or the like from entering from the hole.

  Next, a method for refurbishing the existing sash frame 20 in the upper frame of the sash frame will be described with reference to FIG. When the existing sash frame 20 is removed, the fin portion 22 attached to the housing 10 is also cut along the length direction with respect to the upper frame (FIG. 3A). Similar to the vertical frame, the cut portion is below the portion where the existing sash frame 20 is attached with screws or nails 12. Then, as shown in FIG. 3B, the existing sash frame 20 is removed together with the outer wall 40. As a result, the cut fin portion 22a remains in the housing 10, but there is no problem because no particular demerit occurs as described above. And the new sash frame 50 is installed in the part which removed the existing sash frame 20. The sash frame 50 to be installed includes a portion that does not interfere with (i.e., does not overlap) the remaining fin portion 22a and is in contact with the housing 10 and is formed in a groove shape. Then, as shown in FIG. 3B, a screw, a nail 12 or the like is driven into the housing 10 from the groove 53, and the upper frame of the sash frame is fixed to the housing 10. The groove portion 53 can be appropriately sealed to ensure hermeticity and prevent rainwater from entering. Further, by removing the outer wall 40, the gap formed between the existing outer wall 40 is filled with a sealing material 42 to prevent rainwater from entering, and the new sash frame 50 is held (FIG. 3 (C)).

  In FIG. 3, the sash frame 50 to be newly installed is formed on the outside with a groove portion 53, but as shown in FIG. The portion 53a may be formed. Due to the presence of the flange portion 53a, when the sealing material 42 is filled with the existing outer wall 40, the adhesion between the sealing material 42 and the newly installed sash frame 50 is improved, and the sash frame 50 is fixed. While ensuring, it can prevent rainwater from entering.

  Next, a method for refurbishing the existing sash frame 20 in the lower frame of the sash frame will be described with reference to FIG. Even in this lower frame, the existing sash frame 20 is cut along the length direction together with the fin portions 22 (FIG. 5A) and removed together with the cut outer wall 40 (FIG. 5B). Then, a new sash frame 50 is installed at the removed place, but it is desirable that the newly installed sash frame is configured as a drainer 57 (that is, a shield portion) provided integrally or separately (see FIG. 5 (C)). In other words, by installing a new sash frame 50, it is configured to cover most of the removed outer wall portion with this drainer 57. Thereby, the part which cut off the outer wall 40 will be covered with the roughly draining 57, and an external appearance will not be impaired. Furthermore, the sealing material 42 is filled between the lower surface of the drainer 57 and the remaining end surface of the outer wall 40, thereby preventing rainwater from entering the outer wall 40 from this portion.

  Therefore, according to the remodeling method of the existing sash frame 20 according to the present embodiment, it is not necessary to largely tear the outer wall 40 when removing the existing sash frame 20, and even if it is greatly broken, it is newly installed. Since it can be covered with the sash frame 50 to be performed, labor and cost for repairing the outer wall 40 can be greatly reduced.

  The present invention can be used in the field of renovating existing sash frames, for example, in the construction industry. Moreover, the sash frame used for the remodeling method of this existing sash frame can be implemented in the manufacturing field of the sash frame.
