Description

  The present invention relates to a renovation sash for refurbishing existing windows provided in a building.

  Conventionally, a cover method has been adopted as a method of refurbishing existing windows. In the refurbished sash refurbished by this cover method, a new frame is attached to the existing frame attached to the opening of the building so as to cover the inner peripheral side (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2006-94771

  Some refurbished sashes are provided with a base material that forms a mounting surface for mounting a new frame on the inner peripheral side of an existing frame. The base material is attached to each of the existing upper frame, the existing lower frame, and the existing vertical frame. When the base material is attached to the existing upper frame and the existing lower frame, the base material is fixed using standing wall portions such as guide rails originally provided on the existing upper frame and the existing lower frame.

  When fixing the base material to the standing wall portion of the existing upper frame using an attachment screw from the indoor side, as shown in FIG. 10, the mounting member 602 provided on the back surface of the base material 600 is attached to the standing wall portion 111a, The mounting screws 601a and 601b need to be screwed obliquely from the indoor side so that the mounting screws 601a and 601b pass through the mounting member 602 and the standing wall portions 111a and 111b. At this time, when the fixed part is in a position close to the indoor side, the mounting screw 601b on the indoor side particularly interferes with the frame member 500 or the like disposed on the indoor side of the existing upper frame 110, and the mounting is difficult. There was a problem.

  Such a problem is particularly noticeable when the existing frame is an external type attached to the outdoor side of the opening of the building. This is because, in the external type, the protruding height of the standing wall portion of the existing upper frame for attaching the base material is lower than the frame member or the like disposed on the indoor side from the standing wall portion. Even in the case of not being an external type, when the standing wall portion of the existing upper frame is cut short when attaching the new frame, the same problem as described above may occur.

  Accordingly, an object of the present invention is to provide a modified sash that can easily attach a base material for attaching a new upper frame to an existing upper frame from the indoor side with respect to the existing upper frame.

  (1) The refurbished sash according to the present invention is a base material attached to the inner peripheral side of an existing upper frame (for example, an existing upper frame 110 to be described later) attached to an opening (for example, an opening 2 to be described later) of a building.

(E.g., a remodeled sash 1 described later), and the existing upper frame has a standing wall portion (e.g., guide rails 111a, 111b described later) standing downward, and the base material is There is an attachment member (for example, an attachment member 132 described later) attached to the standing wall portion, and the attachment member is an indoor side holding piece (for example, described later) disposed so as to sandwich the standing wall portion from the indoor side and the outdoor side. Indoor side clamping piece 32f) and an outdoor-side clamping piece (for example, an outdoor-side clamping piece 132g described later), and between the standing wall portion and the indoor-side clamping piece or the outdoor-side clamping piece, along the standing direction of the standing wall portion The vertical wall portion is clamped between the inserted mounting screw (for example, a mounting screw 133a described later) and the outdoor-side clamping piece or the indoor-side clamping piece, thereby being attached to the vertical wall portion. .

  (2) In the modified sash described in (1), it is preferable that the standing wall portion is a guide rail for an existing shoji (for example, guide rails 111a and 111b described later).

  The present invention can provide a modified sash that can easily attach a base material for attaching a new upper frame to an existing upper frame from the indoor side with respect to the existing upper frame.

A plurality of the vertical frame base members 330 and 430 are attached to the inner peripheral side of the existing vertical frames 310 and 410 at intervals in the length direction of the existing vertical frames 310 and 410. Thus, the vertical frame base members 330 and 430 form a substantially flat mounting surface for the new vertical frames 320 and 420 on the inner peripheral side of the existing vertical frames 310 and 410. The new vertical frames 320 and 420 are attached to the surfaces of the vertical frame base members 330 and 430.

The attachment structure of the vertical frame base members 330 and 430 will be further described.
First, the outdoor side of the vertical frame base members 330 and 430 is attached to the existing vertical frames 310 and 410 using the most outdoor fins 311a and 411a provided on the existing vertical frames 310 and 410. That is, on the back surface of the vertical frame base members 330 and 430 on the outdoor side, there are a pair of attachment pieces 331 and 431 that are erected in parallel so as to sandwich the fins 311a and 411a.

  Between the mounting pieces 331 and 431, the fins 311 a and 411 a are sandwiched from the surface side of the vertical frame base members 330 and 430 along the direction in which the fins 311 a and 411 a and the mounting pieces 331 and 431 are erected. Screws 332 and 432 are screwed in. Accordingly, the fins 311a and 411a are sandwiched between the attachment pieces 331 and 431 (in this embodiment, the inner surface of the attachment piece on the outdoor side of the attachment pieces 331 and 431) and the attachment screws 332 and 432, and the vertical frame base material 330 The outdoor side of 430 is fixed to the existing vertical frames 310 and 410.

  On the other hand, the indoor sides of the vertical frame base members 330 and 430 are fixed to the inner peripheral surfaces of the existing vertical frames 310 and 410 by brackets 333 and 433.

  The window frame 10 having the above configuration is framed into a rectangle by the upper frame 100, the lower frame 200, and the left and right vertical frames 300 and 400. As a result, the new frame (new upper frame 120, new lower frame 220, and new vertical frames 320, 420) of the refurbished sash 1 passes through the base members 130, 230, 330, 430, and the existing frame (the existing upper frame 110). The existing lower frame 210 and the existing vertical frames 310 and 410) are attached so as to cover the inner peripheral side.

  In the window frame 10 shown in the present embodiment, the new upper frame 120, the new lower frame 220, and the new vertical frames 320, 420 are made of a metal material such as aluminum. These new upper frame 120, the new lower frame 220, and the new vertical frame Resin angle members 150, 250, 350, and 450 are provided on the indoor side of the frames 320 and 420, respectively. Thereby, the window frame 10 has heat insulation.

  The resin angle members 150, 250, 350, and 450 are disposed with a space between each of the resin angle members 150, 250, 350, and 450, and angle covers 151, 251, 351, and 451 are attached thereto, respectively. Further, the boundaries between the angle covers 151, 251, 351, 451 and the inner peripheral surface 500 a of the frame member 500 are shielded by L-shaped parting materials 152, 252, 352, 452 fixed to the frame member 500.

  Next, a specific structure for attaching the upper frame base member 130 to the existing upper frame 110 will be described with reference to FIGS. 4, 8, and 9. FIG. 8 is a bottom view showing a state in which the upper frame base member 130 is looked up from below, and FIG. 9 is a sectional view showing the upper frame base member 130 in an exploded manner along the line AA in FIG. . As shown in FIG. 4, the upper frame base material 130 includes a base material main body 131 that covers the inner peripheral side of the existing upper frame 110 in the indoor and outdoor directions, and a back surface of the base material main body 131 (a surface on the existing upper frame 110 side). ) And a mounting member 132 provided separately from the base material main body 131.

  As shown in FIG. 9, the base material main body 131 integrally includes a rising piece 131 a that rises from the outdoor end of the base material main body 131 toward the existing upper frame 110. The upper end of the rising piece 131a is integrally provided with an attachment piece 131b that extends substantially parallel to the base material body 131 toward the indoor side and to which the attachment member 132 is attached. Further, the base material main body 131 has a pair of long holes 131f that are long in the indoor and outdoor directions for screwing the attachment member 132.

  The width (length in the indoor / outdoor direction) of the mounting piece 131b is formed smaller than the width between the guide rails 111a and 111b of the existing upper frame 110. The attachment piece 131b has a long hole 131c that is long in the indoor and outdoor directions.

  In the middle of the rising piece 131a, there is a groove 131d projecting in an L shape toward the outdoor side. The groove 131d has a shape that opens upward (to the existing upper frame 110 side), and is formed so as to accommodate the lower end portion of the guide rail 111a on the outdoor side of the existing upper frame 110, as shown in FIG. Has been.

  A connecting portion between the attachment piece 131b and the groove 131d is inclined obliquely toward the indoor side from the groove 131d to the attachment piece 131b. A screw hole 131e for screwing the base material main body 131 to the guide rail 111a on the outdoor side of the existing upper frame 110 from the indoor side toward obliquely upward is formed in this connection portion.

  As shown in FIG. 8, in the base material main body 131, the portion above the groove 131d is formed longer than the length of the base material main body 131 (the vertical length in FIG. 8). The base material body 131 protrudes from both ends in the length direction. The long hole 131c and the screw hole 131e are respectively arranged at portions protruding from both ends of the base material body 131.

  The attachment member 132 is disposed on the indoor side of the rising piece 131a of the base material body 131. A leg portion 132a attached to the back surface of the base material main body 131 and an attachment plate portion 132b extending substantially parallel to the attachment piece 131b of the base material main body 131 from the upper end portion of the leg portion 132a toward the outdoor side.

  The lower end portion of the leg portion 132a extends toward the indoor side, and integrally includes a contact portion 132c that contacts the back surface of the base material body 131. Screw holes 132d are formed in the contact portions 132c at positions corresponding to the respective long holes 131f formed in the base material body 131.

  The width (length in the indoor / outdoor direction) of the mounting plate portion 132b is formed to be smaller than the width between the guide rails 111a and 111b of the existing upper frame 110. A screw hole 132e is formed in the attachment plate portion 132b so as to correspond to the elongated hole 131c of the attachment piece 131b of the base material body 131.

  The attachment member 132 has an indoor side holding piece 132f and an outdoor side holding piece 132g arranged so as to hold the indoor side guide rail 111b of the existing upper frame 110 from the indoor side and the outdoor side.

  The indoor side sandwiching piece 132f is arranged so as to project in an L shape from the middle of the leg portion 132a to the indoor side, and upward (in the existing upper frame 110 side) along the standing direction of the guide rail 111b of the existing upper frame 110. It extends toward. Thus, a groove having a shape opening upward is formed on the indoor side of the leg portion 132a. A screw hole 132i is formed in the groove bottom portion 132h that connects the lower end portion of the indoor side clamping piece 132f and the leg portion 132a.

  The outdoor side sandwiching piece 132g extends upward (to the existing upper frame 110 side) along the standing direction of the guide rail 111b of the existing upper frame 110 from the indoor side end of the mounting plate portion 132b. In this embodiment, the connecting portion between the leg portion 132a and the mounting plate portion 132b of the mounting member 132 is inclined obliquely toward the outdoor side from the leg portion 132a to the mounting plate portion 132b, but the outdoor side holding piece 132g. The indoor side surface is the same surface as the indoor side surface of the leg portion 132a. Therefore, the outdoor side clamping piece 132g may be formed so as to extend integrally and continuously from the leg portion 132a. When the outdoor side clamping piece 132g is formed so as to extend integrally and continuously from the leg portion 132a, it does not necessarily have to protrude upward from the mounting plate portion 132b.

  As shown in FIG. 8, in the attachment member 132, the portion above the indoor side holding piece 132f is formed to be longer than the length of the base material body 131 (the vertical length in FIG. 8). The base material body 131 protrudes from both ends in the length direction. The screw holes 132e and 132i are respectively arranged at portions protruding from both ends of the base material main body 131.

  When attaching the upper frame base member 130 having such a configuration to the existing upper frame 110, first, the attachment member 132 is attached to the existing upper frame 110. Specifically, the mounting plate portion 132b of the mounting member 132 is inserted between the guide rails 111a and 111b of the existing upper frame 110, and is installed between the indoor side holding piece 132f and the outdoor side holding piece 132g. The frame 110 is accommodated so that the lower end portion of the guide rail 111b on the indoor side is sandwiched. At this time, the guide rail 111b is arrange | positioned so that the outdoor side clamping piece 132g may be contact | connected. In this state, as shown in FIG. 4, the mounting screw 133a is screwed into the screw hole 132i of the groove bottom portion 132h from the lower side in the substantially vertical direction.

  Here, the interval between the indoor side holding piece 132f and the outdoor side holding piece 132g is set to be slightly narrower than the dimension obtained by adding the thickness of the guide rail 111b and the outer diameter of the thread portion of the mounting screw 133a. Therefore, when the mounting screw 133a is screwed between the guide rail 111b and the indoor side clamping piece 132f, the guide rail 111b is clamped between the outdoor side clamping piece 132g and the mounting screw 133a. At this time, the thread of the mounting screw 133a bites into the guide rail 111b and the indoor side holding piece 132f, so that the mounting screw 133a does not fall out and the mounting member 132 can be firmly fixed to the guide rail 111b.

  In addition, since the mounting screw 133a can be screwed into the screw hole 132i in a substantially vertical upward direction from below along the standing direction of the guide rail 111b, the frame member 500 or the like has a hindrance to mounting as in the past. The attachment member 132 can be easily attached from the indoor side.

  After the attachment member 132 is attached to the existing upper frame 110 in this way, the base material main body 131 is attached to the guide rail 111a on the outdoor side of the existing upper frame 110. Specifically, the attachment piece 131 b of the base material body 131 is inserted between the guide rails 111 a and 111 b of the existing upper frame 110. The attachment piece 131 b is overlapped with the attachment plate portion 132 b of the attachment member 132, and the base material main body 131 is in contact with the contact portion 132 c of the leg portion 132 a of the attachment member 132. At this time, the lower end portion of the guide rail 111a on the outdoor side of the existing upper frame 110 is accommodated in the groove portion 131d.

  In this state, the mounting screw 133b is inserted into the screw hole 131e of the base material main body 131 obliquely upward from the indoor side. The attachment screw 133b is screwed into the guide rail 111b accommodated in the groove 131d. Thereby, the outdoor side of the base material main body 131 is fixed to the guide rail 111b.
