BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window used in a middle-to-high-rise apartment house.

[0002]

2. Description of the Related Art A sash for a window of a building is, for example, a window plate, for example, a glass plate, which is fitted and held in a frame member fixed to concrete, in an upper frame, a lower frame and left and right vertical frames. It consists of a set of shoji, and the frame is intended to ensure the performance of watertightness, airtightness, sound insulation, etc. when the shoji is closed, and to support the wind pressure applied to the glass plate. Japanese Patent No. 4665 discloses a frame in which an outer flange and an inner flange are connected by a web to form a swallowing groove for a glass plate or a panel.

[0003]

[Problems to be Solved by the Invention] The frame described in Japanese Utility Model Publication No. 53-4665 supports a panel such as a glass plate or a window plate and maintains watertightness and airtightness. The cross-sectional structure of the members is large in order to maintain the wind pressure resistance, and the joint frames where the inner and outer sashes overlap have swelling, especially the frame of the window frame members used for middle and high-rise apartment buildings. In view of the wind pressure, it becomes excessively large, the material is increased, the cross-sectional shape becomes complicated, the processing time is increased, and the living space is narrowed due to the bulging of the frame.

[0004]

[Means for Solving the Problems] The present invention has been made in view of such problems, and the inventors of the present invention have paid attention to the fact that the Young's modulus of glass and frame, that is, aluminum, is very similar, In order to maintain the conventional performance with a simple structure close to the sashless that does not expose the frame from the viewpoint or the conventional structure and maintain the conventional performance, a set of shoji that fastens the glass plate to the upper and lower frame and the left and right vertical frame , Upper and lower frames, left and right vertical frames, in a sliding window movably fitted into an opening of a wall surface, a cross section of a support surface of the frame supporting the glass plate.
And L-shaped bent shape to the indoor side, the a supporting end face of the glass plate surface and windows brought joining the entire circumference of the edge in the structural sealant, the inner surface of the callings mating side vertical glass plate outer shoji At each of the edge and the vertical edge of the outer surface of the glass plate of the inner sash, a molded member of an elastic body that protrudes and engages in the in-plane direction of the sash when the inner and the outer sash is sealed is protruded. Provide windows.

[0005] The structural sealing material used here is also called a structural sealing material, which is a paste or putty before curing, and a rubber exhibiting rubber elasticity after curing. Tensile stress (50%
Modulus) is ² kgf / cm ² or more. Materials include silicone, polysulfide, polyurethane, and polyester. One-pack and two-pack
There is a liquid type, medium modulus (50%
Modulus is 2-4Kgf / cm ² ), high modulus type (5
A 0% modulus is ² to 8 kgf / cm ² ) and an ultra-high modulus type (50% modulus is 8 kgf / cm ² or more), and a silicone-based structural sealing material is preferably used.

[0006] The molded member may be formed of the above-mentioned structural sealing material, or a molded elastic body, for example, rubber may be adhered to a glass plate. It is desirable to have an appropriate thickness in order to secure wind resistance.

[0007]

[Function] By using the support surface of the frame that joins and supports the periphery of the glass plate with a structural sealing material, the glass plate can be taken out of the room in a sashless manner that does not expose the vertical frame or the combination frame when viewed from outside. The design is enhanced, and the simple frame shape eliminates the swelling of the combination, making it possible to effectively use the indoor and outdoor spaces, and in addition to reducing the use of materials.

Less than. The edge allowable bending stress of 180.0 kg /
Although it was larger than cm ² , it was only necessary to use a glass plate one rank thicker to make it within the allowable value, and it was confirmed that the wind resistance could be directly applied to the glass plates 12 and 12.

[0013] The watertight performance is a pressure of 7 to 23 kg / m.
^{At 2} (average pressure 15 kg / m ² ), a slight leak was observed from the joint, but the lower frame was made of a commonly used shoji water pool structure and retested to confirm that there was no abnormality. Then, the pressure was increased to 25 to 75 kg / m ² (average pressure: 50 kg / m ² ), but no water leakage was observed.

It has been confirmed that, among the three-sided supports, the bending of the mating portion and its stress are cleared in the outer sashes 4 and 5, so that the upper frame into which the guide projection 20 of the upper frame 3 is inserted.
Except for the cross-sectional shape of the lower frame 11 to which the door wheels 6 'and 7' are mounted, the vertical frames 8 and 8 'and the combined frames 9 and 9' can have a simple cross-sectional shape. Expected rigidity is glass plate
12 and 12, and the role of the combination frames 9, 9 '
Only the mechanism for maintaining the watertightness of the outer sashes 4 and 5 can be provided.

[0015] Therefore, since the rigidity of the glass plate 12 is used instead of maintaining the wind resistance strength of the conventional mating frames 9 and 9 ', the mating frame supports and protects only the inner and outer glass plates 12 and 12. Only by adding the properties, the cross-sectional shapes of the combination frames 9, 9 'can be made extremely small, and the structure of the glass surface of the appearance can be made a neat design without being obstructed by the frames.

[0016]

According to the present invention, the cross-sectional shape of the frame is reduced to an L-shape by bonding the glass plate of the shoji to the frame with a structural sealing material and applying the wind-resistant strength acting on the shoji to the glass plate. The effect is remarkable, for example, it is possible to easily attach accessories such as curtains by improving the design without exposing it to the outdoor side, reducing the amount of frame material, and reducing the swelling of the combined frame. It is.
