Description

  The present invention relates to a refurbished sash, and more particularly to a refurbished sash by a cover method and a sash refurbishing method thereof.

  Several decades have passed since the aluminum sash was used instead of the steel sash, and the sash refurbishment of the aluminum sash has been carried out by, for example, a cover method. In this case, the upper frame and the left and right side frames are generally Since it is constructed in a relatively simple shape compared to the lower frame, the new upper frame and the left and right new side frames in the new sash frame are used as the reference frame for the existing upper frame and the left and right existing side frames in the existing sash frame. However, it can be installed relatively easily by directly attaching and fixing inside the opening surface without installing an intervening metal fitting that narrows the opening between them. Since the lower frame board that descends to the outside of the room is configured with a relatively complex shape with upward guide rails and standing uprights on the indoor side, the new lower frame in the new sash frame is installed under the existing sash frame. Based on the frame It is common to use a fitting that can support the load of the newly installed lower frame as the frame. However, if this fitting is used, the newly installed lower frame will rise significantly from the position of the existing lower frame, resulting in an increase in the narrowing of the opening. There is a drawback of doing.

  For this reason, for example, as one form of the cover construction method, the guide rails, particularly the guide rails on the indoor side remain, while the guide rails on the outdoor side remain cut and removed from the lower frame substrate, and the remaining part is opened. A hanging piece of the L-shaped channel material is fixed to the side surface of the guide rail on the indoor side, and the widthwise indoor side portion of the newly installed lower frame configured in a step shape is placed and fixed on the horizontal piece of the L-shaped channel material. In addition, a storage structure has been proposed in which the lower end of the outdoor side of the newly installed lower frame is fixed to the existing lower frame, and in this case, the guide rail on the outside of the room is cut and removed to open the portion. As a result, the outdoor guide rail is prevented from coming into contact with the lower frame substrate of the newly installed lower frame. As a result, the newly installed lower frame is stepped outward from the upper position of the L-shaped channel material fixed to the guide rail on the outdoor side. Installed to descend to At this time, by omitting the standing erection on the indoor side of the newly installed lower frame, it is possible to prevent as much as possible the narrowing of the opening caused by the newly installed lower frame protruding greatly upward from the window frame installed on the existing lower frame. .

A new upper frame 21 and a new vertical frame 22 are installed, and an aluminum frame 61 is disposed between the new upper frame 21 and the new vertical frame 22 and the existing frame 15 to cover them.

At this time, the newly installed lower frame 31 in the newly installed sash frame is formed as a two-component structure in which the lower frame main body 32 and the bracket 40 are integrated, and the lower frame main body 32 is placed on the lower frame substrate 33 with a sliding shoddle. These guide rails are used for a sliding sash having a pair of inner and outer guide rails 34 for opening / closing guidance, and two standing ridges 35 for installing a sealant 52 on the indoor side between the guide rails 34 and on the indoor side. 34 and the upright ridge 35 are configured to have the same height, and the bracket 40 is configured to include an indoor upper window stand mounting strip 41 and an outdoor lower support strip 43. The strip 41 is mounted or fixed on the window base 16 directly or via the existing window base mounting strip of the existing lower frame, while the lower frame main body 32 is positioned on the inner side in the width direction on the support strip 43 on the lower outdoor side of the bracket 40. Part By Taise' fixed to existing sill 13 or precursor to a mounting fixed and outdoor side lower end portion of the new lower frame 32, the height of the guide rails 34 and the upright strip 35 of the lower frame body 32 It is assumed that the new lower frame 31 is installed so as to cover the existing lower frame 13 as a storage that is the same as or substantially the same as the above-mentioned window base mounting strip 41.

  The lower frame main body 32 of the new lower frame 31 of the present example is provided with a lower frame substrate 33 and a guide rail 34 for opening and closing the sliding shoji 71. In this example, the lower frame main body 32 is provided. This means that the lower frame substrate 33, a pair of inner and outer guide rails 34 that open and close the sliding frame that stands up on the lower frame substrate 33, and the guide rail 34 between the guide rail 34 and the indoor side, respectively, The guide rail 34 and the upright strip 35 have the same height, and the bracket 40 of the present example has the same height. In addition to the above-mentioned window base mounting strip 41 and support strip 43, a side stand ridge 45 is provided along the outside side surface of the window base 16, and the side stand ridge 45 is superposed on the indoor side standing strip of the existing lower frame 13 to form a window. Attached to the outside side of the room 16 or Constant, in the present embodiment is as having been additionally provided.

  That is, in this example, the lower frame main body 32 and the bracket 40 are both made of an aluminum extruded material, a tapping hole is installed in the lower frame main body 32, and a tapping screw is screwed into the newly installed vertical frame 22. While the frame is formed as a new sash frame, the bracket 40 is made of an independent member in the same manner as the U-shaped channel member 23 used to install the new upper frame 21 and the new vertical frame 22 outside the frame as the new sash frame. It is as an eggplant.

  The lower frame main body 32 of this example includes a lower frame substrate 33, a pair of inner and outer guide rails 34 standing on the lower frame substrate 33 and having the same height. The two standing ridges 35 that open the airtight material receiver at the upper end for installing the airtight material 52 in contact with the shoji 71 toward the outdoor side and have the same height as the pair of inner and outer guide rails 34; A pair of inner and outer mounting leg portions 36 projecting downward in the same length so as to be positioned below the indoor side guide rail 34 and the standing ridge 35 on the indoor side, and an intermediate portion of the lower frame substrate 33 Projecting downward so as to cover the outdoor side of the existing lower frame 13, and a downward projecting piece 37 provided with a contact fixing portion 38 at the lower end thereof.

  The new lower frame 31 comprising the lower frame body 32 and the bracket 40 formed in this way is installed by placing the bracket 40 in advance on the window base 16 and supporting the lower frame body 32 by the bracket 40. In other words, when the window base mounting strip 41 of the bracket 40 is directly on the window base 16 and the existing window base mounting strip of the existing lower frame 13 is already present on the window base 16, it is indirectly connected to the window base 16 through this. In this example, side erection ridges 45 are attached to the outdoor side surface of the window base 16, project from the window base 16 of the bracket 40 to the outdoor side, and the indoor side of the existing lower frame 13. On the support strip 43 arranged so as to be positioned on the guide rail, the widthwise indoor side portion of the lower frame body 32, in this example, the pair of indoor and outdoor mounting legs 36 is mounted and fixed. And the lower outside end of the lower frame body 32 , I.e. the abutment fixing portion 38, the outdoor-side end portion of the existing sill 32, in the present embodiment are made the installation by Taise' fixed screen door rail 14 of the existing sill 13. At this time, the mounting and fixing of the window base mounting strip 41 to the window base 16 is performed by screwing screws 51 at predetermined intervals in the longitudinal direction from the upper surface of the window base mounting strip 41 to the window base 16. At the same time, by fixing the screw 51, the side standing ridge 45 is superposed on the existing indoor side standing ridge, and the attachment is performed. The lower frame main body 32 is placed on the support strip 43 by placing the lower frame main body 32 on the support strip 43 so that the holding ribs 44 of the support strip 43 hook the mounting legs 36 on the indoor side. In addition, the protruding ridges 42 projecting outward from the window table mounting ridge 41 hook the upright ridges 35 on the indoor side so that the indoor ends of the lower frame main body 32 are vertically clamped by the clamping ribs 44 and the protruding ridges 42. Thus, the fixed position can be placed. Accordingly, the lower frame main body 32 is fixedly mounted on the support strip 43 from the upper surface of the lower frame substrate 33, in this example, the upper surface of the indoor-side substrate portion in the fixed position. This may be done by screwing screws 51 at a predetermined interval in the longitudinal direction. Also, the fixing of the lower end of the outdoor side of the lower frame body 32 to the existing lower frame 13 is performed by the contact fixing portion 38. This can be done by screwing screws 51 at predetermined intervals in the longitudinal direction from the outdoor side to the screen door rail 14 of the existing lower frame 13. At this time, the lower frame main body 32 and the bracket 40 in this example have the guide rail 34 and the standing ridge 35 which are the same height as the lower frame main body 32, and the height of the lower frame main body 32 and the bracket 40 is the same as or substantially the same as that of the window base mounting ridge 41. In this example, the height of the guide rail 34 and the upright strip 35 on the indoor side of the lower frame body 32 is set so that the protrusions 42 on the outdoor side of the support strips 43 of the bracket 40 and the window mounting strips 41 are provided. The lower frame main body 32 and the bracket 40 are formed so as to coincide with the height of the guide rail 34 and the end of the upright ridge 35 on the extension line of the window base mounting ridge 41. As a result, the appearance from the indoor side is preferable.

The renovation of the newly installed lower frame 31 in the refurbished sash A of this example is such that the window base mounting strip 41 on the indoor side of the bracket 40 is directly or directly installed on the existing lower frame mounting strip of the bracket 40. And is fixed to the window base 16 through the support frame 43 , and the widthwise indoor side portion of the lower frame main body 32 is placed and fixed on the support strip 43 on the lower outdoor side of the bracket 40, and the outdoor side of the newly installed lower frame 31 is fixed. By fixing the lower end portion to the existing lower frame 13 by cutting and removing the guide rails of the existing lower frame 13, the existing lower frame 13 is covered and the new lower frame 31 is installed in the new sash frame. If the remodeling method of the remodeling sash A is described, a fixing member for fixing the new upper frame 21 and the left and right new vertical frames 22, that is, in this example, the channel member 23 and the connecting member. 24 and the new lower frame 31 After fixing the racket 40 to the existing upper frame 11, the left and right existing vertical frames 12 and the window base 16, the framed new sash frame is fitted into the opening of the existing sash frame, and the new upper frame 21 and the left and right new vertical frames 22 are respectively fitted. This is performed by fixing to the existing upper frame 11 and the left and right existing vertical frames 12 through fixing members and fixing the lower frame body 32 of the new lower frame 31 to the support strip 43 of the bracket 40.

  That is, in this example, the U-shaped channel member 23 and the connecting bracket 24 are fixed to the existing upper frame 11 and the left and right existing vertical frames 12 of the existing sash frame, and the bracket 40 is fixed to the window base 16 of the existing lower frame 13. After that, the newly installed sash frame preliminarily framed is fitted into the existing sash frame, and the lower frame body 32 is placed on the support strip 43 of the bracket 40, and the existing upper sash frame 11, The connecting bracket 24, the new upper frame 21, and the left and right new vertical frames 22 fixed to the left and right existing vertical frames 12 are pulled and fixed by screws 51, and the lower frame body 32 is fixed to the support strip 43 of the bracket 40 and the existing lower frame. 13, screws 51 are fixed, and an aluminum frame 61 is arranged between the new upper frame 21 and the new vertical frame 22 and the existing frame 15. As a result, the new upper frame 21 and the left and right new vertical frames 22 are brought into contact with the existing upper frame 11 and the left and right existing vertical frames 12 through the airtight material 52 by pulling and fixing the screws 51, and the space between them is As a result of being sealed by crimping of the airtight material 52 and between the bracket 40 and the lower frame main body 32 being sealed with the airtight material 52, it is possible to obtain a space with a high degree of airtightness and to arrange the frame 61. The finished appearance can be satisfactorily ensured without exposing the connection fitting 24, the screw 51 and the like to the indoor side.

  3 and 4 show an example of a modified sash in which the expected width of the existing sash frame is about 1 cm larger than the above example, and the existing lower frame 11 of the existing sash frame has an inclined substrate inclined outward. In this example, the new upper frame 21 of the new sash frame, the left and right new vertical frames 22 and the lower frame body 32 of the new lower frame 31 are used in common with those of the above example, and therefore the shoji 71 is also used in common. Similarly, the existing sash frame is covered and a new sash frame is installed and refurbished.

In this example, the newly installed upper frame 21 and the left and right newly installed vertical frames 22 are installed by using the channel material 23 having an intermediate recess in which the middle in the width direction is recessed. Screws 51 are fixed to the existing upper frame 11 and the left and right existing vertical frames 12 from the bottom walls that are respectively fitted and recessed into the openings of the frame 12, while the channel member 23 is placed on the indoor and outdoor flat surfaces, for example, indoors and outdoors. has a length to cover the existing upper frame 11 and the existing vertical frame 12 in the direction a predetermined interval connecting fitting 24 provided with the protruding protrusion protruding toward the opening side in the L-shaped section which is approximately several cm width To the projecting protrusions of the connecting bracket 24, the indoor-side fixing fins of the new upper frame 21 and the left and right new vertical frames 22 are brought into contact with each other, and the screws 51 are respectively attached from the projecting protrusions. Screwed in and the new upper frame 21 and the new The frame 22 was pulled in to the indoor side, and the airtight material 52 installed on the pressure fins at the front end of the outdoor side was pressure-bonded to the outdoor side fins of the existing upper frame 11 and the existing vertical frame 12 in the same manner as described above. As a thing.

  Further, in this example, the bracket 40 of the newly installed lower frame 31 is formed so as to have a step difference from the horizontal window base mounting strip 41 on the indoor side and the window base mounting strip 41 on the outdoor side. It is assumed that the horizontal support strip 43 located on the lower side and the side upright strip 45 are provided, but the window base mounting strip 41 is widened so as to increase the projecting width of the support strip 43 to the outdoor side. The supporting strip 43 is arranged so as to intersect with the connecting portion from the front end side through the connecting portion, and the vertical standing side surface extending downward to the indoor side end portion of the supporting strip 43 extending to the indoor side by the crossing. 45. In the present example, the window base mounting strip 41 has a small rib disposed on the lower surface thereof, and the height of the protrusion from the window base 16 is minimized. The mounting and fixing to the table 16 is performed.

  The bracket 40 of the present example is configured such that the window base mounting strip 41 is mounted and fixed to the window base 16 in the same manner as described above, and the side stand-up strip 45 is attached to the outdoor side surface of the window base 16. The position of the lower frame body 32 can be accommodated to the expected width of the existing sash frame by taking it about 1 cm outside of the above example. By mounting and fixing to the support strip 43, the lower end portion of the outdoor side is fixed to the downward fin or the casing not shown of the existing lower frame 13, so that the expected width of the lower frame main body 32 can be used while being commonly used. It is assumed that changes have been absorbed.

  At this time, the guide rail 34 and the upright ridge 35 having the same height of the lower frame main body 32 in the modified sash A of this example are accommodated so that the height is the same as or substantially the same as the flat upper surface of the window base 16. That is, the guide rail 34 and the upright ridge 35 are set in a position in which about half of the height of the guide rail 34 and the upright ridge 35 is arranged higher than the above-mentioned window pedestal mounting ridge 41. Although protruding from the table 41, the same height as the flat upper surface of the window base 16 is used to ensure a good appearance from the indoor side as described above.

  The remaining structure, the fixed relationship, and the procedure of the refurbishment method are the same as in the above example, so duplicate explanations are omitted.

Each of the above-described refurbished sashes A configured as described above covers the existing lower frame and removes the new lower frame in the new sash frame by cutting and removing the guide rails of the existing lower frame by a simple operation on the indoor side. The sash can be refurbished by the cover method to be installed, and the height of the guide rail and the upright of the lower frame main body is set to be the same as or substantially the same as the above-mentioned window base mounting article, and the flat upper surface of the window base A preferable housing structure capable of preventing the narrowing of the opening as much as possible by preventing the newly installed lower frame 31 of the modified sash A from projecting above the window base 16 so as to prevent the narrowing of the opening as much as possible. As a result, the bracket 40 is provided with the side erection ridge 45 that is fixed to the outer side surface of the window base 16, so that the structural strength and stability of the bracket 40 for mounting the lower frame body 32 on the support ridge 43 are stabilized. The lower frame main body 32 is used for a sliding sash having two standing ridges 35 for airtight material installation to ensure airtightness between the pair of inner and outer guide rails 34 and the lower frame main body 32. By making the heights of the guide rail 34 and the upright ridge 35 the same height, the inner frame 76 is opened and closed and guided by the guide rail 34 so that the lower frame body 32 does not stand up different length. It is possible to mount and remove from the inside and to improve the appearance from the indoor side. In particular, the support strip 43 for mounting and fixing the lower frame body 32 of the newly installed lower frame 31 is positioned on at least the indoor guide rail of the existing lower frame 13, so that the newly installed lower frame 31, particularly the lower frame body thereof, is arranged. Thus, it is possible to refurbish the whole of the existing lower frame 13 by 32, and it is not necessary to cut and remove the guide rail on the outdoor side of the existing lower frame 13, and in a relatively short time by a simple operation on the indoor side. Sash renovation can be completed.

  In addition, if the side stand-up ridge 45 is attached so as to be pulled toward the indoor side when the window base mounting strip 41 is mounted and fixed on the window base 16, the support strip 43 can be stably prevented. However, it is preferable to provide this for the convenience of work, but this can be fixed to the window base 16 as necessary. What is necessary is just to insert a screw and to fix the screw.
