  As can be seen from the above-mentioned patent documents, it is easier to process the window frame, the crosspiece and the like with an aluminum sash, and the cost does not increase.

  However, in the days when aluminum sashes were not used, most of the windows in large buildings used steel sashes. Furthermore, the size of the glass was limited and the workability of the steel sashes Because of the goodness, windows with elaborate designs using a lot of small bars were used.

  In recent years, large buildings such as those described above have become a problem of aging and need to be repaired. In addition, many of these buildings have high cultural value, and it is desirable to replace them with window frames with the same structure as before. However, it is expensive to manufacture the window frames themselves, and technology such as glass putty is used. In some cases, it has been abolished, and there are many cases where it is replaced with an aluminum sash.

  However, when a sash or crosspiece having the same structure as that of steel is formed of an aluminum material, there is a problem in terms of strength.

  Accordingly, the present invention is to provide a glass window structure that can form the same appearance as the assignment of a steel sash, has a predetermined strength, and can improve the workability of the mounting operation.

  Therefore, the present invention provides a frame body made of aluminum material, which is composed of upper, lower, left and right frames, a piece of glass fitted in the frame body, a plurality of vertical bars and both ends supported by the upper and lower frames of the frame body. Is formed by crossing a plurality of horizontal rails supported by the left and right frames of the frame body with a predetermined width, and is constituted by a pair of fixed rails that sandwich and fix the glass from both sides. The frame body and the fixed frame preferably have the appearance of a steel sash, so-called color and design.

  As a result, one glass is attached to one window frame, and the glass is sandwiched and fixed by a fixing bar formed by crossing a plurality of vertical bars and a plurality of horizontal bars. It is only necessary to attach one piece of large glass without the work of attaching each piece of glass to the window frame of each other, and the strength of the fixed beam formed by the vertical beam and the horizontal beam is reinforced by the glass. Therefore, the design can be the same as that of the steel sash.

  Further, it is desirable that an elastic member is interposed between the fixed residue and the glass. With this elastic member, it is possible to form an appearance that is putty-stopped and to absorb vibrations on the glass or glass.

  Further, the vertical beam and the horizontal beam are constituted by a glass fixing block having a hollow inside and a ridge standing along the fixing block, and at the intersection of the vertical beam and the horizontal beam, the vertical beam and One glass fixing block of the horizontal beam is formed with a block-side notch portion having a length corresponding to the width of the glass fixing block at a portion meshing with the other glass fixing block, and the vertical beam and the horizontal beam. Preferably, the other ridge is formed with a ridge-side notch that meshes with one of the ridges of the vertical beam and the horizontal beam that bridge the block-side notch.

  According to the present invention, since the glass is sandwiched and fixed by the fixed beam formed by mounting a single glass and crossing the plurality of vertical beams and the plurality of horizontal beams, it is aged at low cost. The steel sash can be exchanged, and the appearance is not impaired. Further, since the single glass is mounted and is fixed by being clamped by the fixing bar, the mounting operation is easy and the replacement cost can be reduced.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, for example, an old cultural property building glass window structure 1 includes a frame 3 fitted into an opening 2 of a building, and a plurality of horizontal rails to which both ends of the frame 3 are fixed. 4 and a vertical beam 5, and a glass portion 7 that closes a plurality of spaces 6 defined by the horizontal beam 4 and the vertical beam 5.

  In the conventional glass window structure 1, the frame 3 and the fixed beam 10 including the plurality of horizontal beams 4 and the vertical beam 5 are formed of steel, and each glass portion 7 that closes the space 6 defined by them is provided on each glass portion 7. The glass corresponding to the opening area was fitted with putty.

  On the other hand, as shown in FIG. 2, the glass window structure 1 according to the embodiment of the present invention has a frame body 3 fitted and fixed in the opening 2, and both ends are fixed to the frame body 3. The pair of fixed bars 10 and the glass 8 sandwiched and fixed by the pair of fixed bars 10 are configured.

  As shown in FIGS. 2 and 3, the frame 3 includes a pair of horizontal frame portions 3 </ b> A and a pair of vertical frame portions 3 </ b> B. The horizontal frame portions 3 </ b> A and the vertical frame portions 3 </ b> B each have the opening portion. 2 has an outer fixing portion 34 fixed to the peripheral edge of the outer peripheral portion 2, an inner fixing portion 32 formed in a substantially U-shape, and a peripheral wall portion 31 with which the ends of ridges 12A and 12B described below of the fixing bar 10 abut. . The inner fixing portion 32 has an inner groove portion 33 to which the glass 8 is fixed via an elastic buffer fixing member 30, and both ends of the inner groove portion 33 are in contact with the end portions of the fixing bar 10. Touch.

  As shown in FIGS. 2 to 4, the fixed beam 10 is formed by combining a horizontal beam 4 and a vertical beam 5, and each of the horizontal beam 4 and the vertical beam 5 has an internal hollow cross-sectional rectangular shape. The elongated glass fixing blocks 11A and 11B and ridges 12A and 12B integrally formed so as to stand up from substantially the center along the longitudinal direction of the glass fixing blocks 11A and 11B. In this embodiment, the glass fixing block 11B constituting the vertical beam 5 is formed with a notch 13 for fitting the glass fixing block 11A constituting the horizontal beam 4 and a ridge on the notch 13 is formed. 12B is left as the bridge portion 15. On the other hand, the ridge 12A constituting the horizontal beam 4 is formed with a notch portion 14 that meshes with the bridge portion 15 of the vertical beam 5, so that the vertical beam 5 can be fitted into the horizontal beam 4. It can be done. In this embodiment, the notch 13 is formed in the glass fixing block 11B, and the notch 14 is formed in the ridge 12A. However, the reverse configuration may be used.

  In addition, an elastic buffer member 50 is provided between the fixing bar 10 and the glass 8 in order to effectively fix and hold the glass 8. The elastic buffer member 50 is an elastic member such as synthetic resin or synthetic rubber. In this case, the glass 8 is sandwiched and fixed by being attached to the inside of the fixing bar 10. As the elastic buffer member 50, there is a method in which a liquid resin such as a photo-curable resin or a solvent-curable resin is injected between the glass 8 and the fixed bar 10 and then cured.

  As a result, the plurality of horizontal bars 4 and the plurality of vertical bars 5 are fitted in a cross shape to form a fixed bar 10, and the frame body 3 is sandwiched and fixed via the elastic buffer member 50. Fixed to. As a result, the glass fixing blocks 11A and 11B of the horizontal beam 4 and the vertical beam 5 are flush with the side surface of the inner fixing portion 33 of the frame 3, and the ridges 12A and 12B are flush with the peripheral wall portion 31. Is.

  Further, the elastic buffer member 50 can suppress vibration of the glass 8 itself and prevent transmission of vibration from the fixed rail 10 to the glass 8 and can have an appearance similar to that of a conventional putty stopper. In spite of the sheet of glass 8, the appearance of a conventional small window in which a plurality of glasses are fixed to a crosspiece can be maintained.

  Moreover, since the problem of the strength of the fixed beam 10 itself caused by forming the fixed beam 10 with aluminum can be reinforced by the glass 8, problems caused by forming with the aluminum can be solved.

  Furthermore, since the glass 8 is attached to the frame 3 and is fixed by the fixing bars 10 from both sides, the replacement work to a new sash can be performed easily and efficiently, and the replacement cost can be reduced. Is something that can be done.
