Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to windows used in medium-to-high-rise housing complexes, etc.

0002

[Conventional technology]

For example, sashes for windows in buildings have upper and lower frames inside a frame member that is fixed to concrete. From a pair of window panels, such as a pair of glass panels, that are fitted and held within the stile of the left and right stiles. The stile must ensure watertightness, airtightness, sound insulation, etc. when the shoji is closed. The purpose of this is to support the wind pressure applied to the glass plate. Publication No. 53-4665 discloses that the outer flange and inner flange are connected by a web. A stile with glass panes or panels swallowing grooves is disclosed.

0003

[Problem that the invention attempts to solve]

The frame described in Utility Model Publication No. 53-4665 is made of panels such as glass plates or window plates. Support, maintain watertightness and airtightness, and maintain wind pressure strength against the wind pressure that the panel receives. Therefore, the cross-sectional structure of the members is large, and the joining frames where the inner and outer shoji overlap are bulged. In particular, frames for window frame members used in medium- and high-rise apartment buildings should be designed with wind pressure in mind. In addition to increasing the amount of material required, the cross-sectional shape also becomes more complex, which increases processing time. Another drawback was that the living space was narrowed due to the swell of the stile.

[Means to solve the problem]

This invention was devised in view of these problems, and the inventors and others used glass and frames. Focusing on the fact that the Young's modulus of aluminum is extremely similar, A sashless structure that does not expose the frame, or a simple structure similar to that, and In order to maintain the original performance, glass plates were fixed to the upper and lower frames and the left and right frames. A set of shoji is movably fitted into an opening in a wall consisting of upper and lower frames and left and right vertical frames. In the window, the supporting surface of the stile that supports the glass plate is bent in an L shape toward the indoor side. and a window in which the edge of the glass plate is bonded to the support surface with a structural sealant; The matching side vertical edge of the inner surface of the outer shoji and the matching side vertical edge of the outer surface of the inner shoji A molded part of an elastic body that engages in the in-plane direction of the shoji and comes into close contact with the shoji when the inner and outer shoji are sealed. To provide a window with protruding timber.

[0005] The structural sealing material used here is also called a structural sealing material, and is a paste-like or putty-like material before hardening, and after hardening, it becomes rubber elastic. The tensile stress (50% modulus) at that time is 2Kgf/cm ² or more. There are silicone-based, polysulfide-based, polyurethane-based, and polyester-based materials, and there are 1-component and 2-component packaging types, and medium modulus (50% modulus is 2 to 4 Kgf/cm). ² ) It is classified into high modulus type (50% modulus is 2 to 8 Kgf/cm ² ) and ultra-high modulus type (50% modulus is 8 Kgf/cm ² or more), and preferably a silicone-based structural sealant is used.

[0006] The molded member may be formed of the structural sealant described above, or may be molded with An elastic body, such as rubber, may be attached to the glass plate, and the It is desirable that the thickness be appropriate in order to ensure wind pressure resistance.

[0007]

[Effect]

The support surface of the stile, which supports the periphery of the glass plate by bonding it with a structural sealant, makes it possible to A glass plate is installed in the sashless structure, which does not expose the vertical stiles or stiles when viewed from the side. It is a type that can be carried outside the room, which enhances the design, and the simple shape of the stile makes it easy to match. There is no bulge, making effective use of indoor and outdoor space, and also leads to a reduction in materials.

These include rails 6 and 7 arranged on the upper surface of the lower frame 2, and a guide protrusion 20 hanging down from the upper frame 3. The door wheels 6', 7' and upper frames 10, 10' are fitted to the rails, and the shoji 4, 5 are fitted along the rails. move in the in-plane direction.

0010 The constituent members of the inner shoji 4 and the outer shoji 5 are a vertical stile 8 and an inner stile 9 as the inner shoji. , upper stile 10 and lower stile 11, vertical stile 8' and outer stile 9' as outer shoji 5, upper stile 10' and and the lower stile 11', and the glass plates 12, 12 are fixed within the framework of the stile. Each frame 8, 9, 10, 11 and 8', 9', 10', 11' that fixes and holds the board 12 is An L-shaped support surface 13 is provided on the cross section of the fastening part that rises toward the indoor side, and this support surface has a durable , for example, silicone-based structural sealants 14 with weather resistance and high adhesive performance. However, the inner frame 9 has a concave or convex engaging portion 15 on the outdoor side. Engagement in which the exterior matching stile 9' is engaged with the engagement portion 15 in a convex or concave shape toward the indoor side. The engaging portions 15 and 16 are arranged so as to fit together when the inner and outer shoji 4 and 5 are sealed. Watertight, airtight, Attach an airtight member 17 for use.

[0011] Next, on the side of the stile 9 and 9' where the stile is connected to the inside and outside, a A molded member 18 that protrudes to the outside of the room at the shoji 5, and a molded member that projects to the inside of the room on the indoor surface of the outer shoji 5. 19 is installed, and its cross-sectional shape is rectangular, trapezoidal, triangular, and circular with an adhesive surface. The molded members 18 and 19 may be either hollow or circular when the shoji 4 and 5 are closed. protrude from the glass plates 12, 12 so that they touch each other on the sides of the glass plates 12 and 12, and when they come into contact, they come into close contact. In order to , 12, or the same material as the structural sealant 14 used on the glass plate surface. It may be molded from quality material.

[0012]Hereinafter, confirmation of the wind pressure strength of the present invention and its operation will be explained. A specimen similar to three-sided sliding sliding shoji 4 and 5 was attached to a wind pressure tester, and the stress of glass plates 12 and 12 and the watertightness of molded members 18 and 19 were confirmed. 1. Shoji glass Dimensions: (W) 900 x (H) 1,800 x (t) 10 mm Sealing material: SE797 (manufactured by Toray Dow Corning Silicone Co., Ltd., 2-component type silicone sealing material, 50% modulus: 4.6 Kgf /cm ² ) 2. Molded part Material: Glued chloroprene Shape: Trapezoidal cross section 3. Installation state of shoji A molded member is provided at the position of the joining frame, and the three sides excluding the molded member side are hermetically fixed with a steel sash and a structural sealant, and the joined part is sealed with the molded member. 3. Wind pressure performance Positive pressure: 240kg/m ² Negative pressure: -240kg/m ² 4. Watertight performance Pressure: 7 to 23 kg/m ² , 25 to 75 kg/m ² 5 test results (positive pressure) (negative pressure) Deflection of joint part Outdoor side, 20.5 -20.4mm Indoor side 20.9 -20 .0mm Stress generated at the joining part 241.5 228.8Kg/cm ² The deflection of the glass plate is larger than the calculated value for a flat plate supported on four sides (±14.5 mm), but the calculated value for a simple three-sided support (±14.5 mm) 25.9 mm), no difference was observed between indoor and outdoor, and the maximum generated stress was also larger than the calculated value (±205.0 Kg/cm ² ) for a flat plate supported on all four sides, which is a simple This is smaller than the calculated value for three-sided support (±268.0 Kg/cm ² ). Although it is higher than the allowable edge bending stress of 180.0 Kg/cm ² , in order to make it within the allowable value, it is sufficient to use a glass plate that is one rank thicker, and the wind pressure resistance strength can be directly borne by the glass plates 12, 12. It was confirmed that this is also possible.

Regarding the watertight performance, at pressures of 7 to 23 kg/m ² (average pressure 15 kg/m ² ), a small amount of water leaked from the joint part, but the lower frame was of a water-retention structure of a shoji that is normally used. A retest was conducted, and after confirming that there were no abnormalities, the pressure was increased to 25 to 75 kg/m ² (average pressure 50 kg/m ² ), but no water leakage was observed.

[0014] Inner and outer shoji 4 and 5 of the three-side support, the deflection and stress of the joint parts are suppressed. Since it has been confirmed that the upper stile 10 is inserted into the guide protrusion 20 of the upper stile 3, , except for the cross-sectional shape of the lower stile 11 to which the door wheels 6' and 7' are attached, the vertical stile 8 and 8' and the combined stile 9 and 9' can be made into a simple cross-sectional shape, and the expected rigidity of the frame is that of a glass plate. 12 and 12, and the role of the matching frames 9 and 9' is to keep the inner and outer shoji 4 and 5 watertight. This mechanism can only be used.

[0015] Therefore, instead of maintaining the wind pressure strength of the conventional joint frames 9 and 9', Since the rigidity of the glass plate 12 is used, the combined frame is made of only the inner and outer glass plates 12, 12. The cross-sectional shape of the connecting frames 9 and 9' is made extremely small to provide only support and confidentiality. The structure of the exterior glass surface is not obstructed by the stile, making it neat and tidy. It can have a different design.

[0016]

[Effect of the idea]

This invention connects the glass plate of the shoji to the frame using a structural sealant, and The cross-sectional shape of the stile is L-shaped by having the glass plate bear the wind pressure strength. By making it smaller and improving the design without exposing it to the outside, reducing the amount of frame material and making it easier to By reducing the swell of the stile, accessories such as curtains can be attached easily. The effects are remarkable, such as the ability to
