Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a dead-end or sliding window used in a middle-high-rise apartment house or the like, or a framed glass used for an outer wall.

(Prior Art) Conventionally, when a window glass is attached to a concrete structure, first, a metal sash is fixed to the opening and the face material fitting groove of the sash is used to fit the sash. In JP-A-62-32186, a hard elastic member, which is a backup material formed of a hard elastic material, is loaded into the joint between the glass and the window frame at the joint between the window glass and the window frame that supports the window glass. , A sealing structure in a window frame or the like of a glass window in which a non-adhesive layer is formed in a gap between at least the caulking material filled in the joint outer portion of the hard elastic member and the hard elastic member is disclosed. The panel used for the above has a mounting edge frame for mounting the glass plate on a glass support frame on the inner surface of the four peripheral edges of the rectangular glass plate, and is attached to a frame body 6 as shown in FIG. It is known that the gap between the sealing members 12 is filled with the structural sealing material 8 and hard-bonded thereto. Further, for example, in Japanese Utility Model Laid-Open No. 62-49546, there is a strip-shaped strip on the back surface of glass, panel or the like. A molding elastic body in which a molding elastic body is adhered, and a frame member mounted on a pillar of a building is engaged with a mounting groove formed on a non-adhesive surface of the elastic body, and glass, a panel, or the like is supported as a wall surface. A surface-adhesive support structure for glass, panels, etc. by the body is disclosed.

(Problems to be solved by the invention) In the mounting structure of the window glass, Japanese Utility Model Laid-Open No. Sho 62-32186 discloses a window frame sash having a fitting groove, and a sealing material or the like is filled between the groove and the glass plate. Since the sash cross section is significantly larger than the thickness of the glass plate and the processing cost is added in addition to the material, the outer wall panel of Japanese Utility Model Publication No. 62-49546 is not available. Since the adhesive is applied to the inner surface of the four edges of the glass plate and is bonded to the mounting frame directly or through the molded elastic body, the cured adhesive is unsightly when viewed from the outside of the glass plate, and Since the glass plate joined to the outdoor side is exposed, there is a defect that the edge portion is cut off due to accidental collision.

(Means for Solving Problems) The present invention aims to solve the above-mentioned problems of the prior art, and a glass plate surface and at least one surface of a frame body provided on the outer periphery of the glass plate. Are arranged so that
Provided is a glass with a frame, which is joined only by a gap between the peripheral end face of the glass plate and the inner peripheral end face of the frame with an injecting structural sealing material, preferably the end face of the glass plate, or the frame body. Provided is a glass with a frame, in which a chamfering process is performed on a butting surface with and a groove portion having a V-shaped or X-shaped butted cross-sectional shape is provided.

The structural sealing material used here is also called a structural sealing material.It is a paste or putty-like sealing material before curing and shows rubber elasticity after curing. Stress (50% modulus)
Is ² Kgf / cm ² or more. Materials include silicone type, polysulfide type, polyurethane type, polyether type, etc. There are 1-pack type and 2-pack type in packaging form, and the modulus is medium modulus (50% modulus is 2 to 4 Kgf / cm ² ), high modulus type (50% modulus is 2-8 Kgf / cm ² ), excess high modulus lie (8 Kgf / cm ²
Above, the silicone-based structural sealing material is preferably used.

The thickness of the glass plate used here is preferably 8 mm or more in order to secure an adhesive area.

FIG. 3 is a cross-sectional view showing a main part of the joining example of FIG. 3 applied to an exterior panel of another embodiment, and FIG. 3 is a cross-sectional view of the main part showing a conventional joining example.

An upper frame 2 provided with a rail groove 1 made of aluminum material, a vertical frame 3,
4, a lower frame 5 having a groove for fitting a roller (not shown)
The glass plate 7 is inserted into the frame body 6 assembled in a square shape, and the gap between the inner peripheral surface of the frame body and the end face of the glass plate 7 has durability, weather resistance, and adhesiveness with glass or metal of the frame material. A framed glass 9 into which a particularly excellent structural sealing material 8 is injected and filled, and the glass plate 7 and the frame body 6 are bonded and integrated by curing adhesion of the structural sealing material is used as a sliding door of a window glass. Become.

In the case of a thick plate that can secure a sufficient bonding area on the end surface of the glass plate 7, the inner peripheral surface of the frame body 6 and the end surface of the glass plate 7 may simply be butted, but the end surface of the glass plate 7 and the frame body A groove portion having a V-shaped or X-shaped butted cross-sectional shape by chamfering either or both of a part of the inner peripheral surface of 6
10 may be provided, and the groove may be filled with the structural sealing material 8 so as to have a joint structure as shown in FIG.
The V-shaped butt cross-sectional shape referred to here is the glass plate 7
Either one of the cross-sectional shape of the end surface when the end portion of the blade is cut and the cross-sectional shape when the end portion of the inner peripheral surface of the frame body 6 is cut is substantially V-shaped. , X-shaped butted cross-sectional shape is that the cross-sectional shape of both the end of the glass plate 7 and the end of the inner peripheral surface of the frame body 6 are substantially V-shaped, and the cross-sectional shape in the butted state is substantially X-shaped. It has shown that it has become.

Further, as shown in FIG. 2B, a fitting plate 11 that widens the cross-sectional shape of the frame body 6 and projects to the outer peripheral portion thereof is provided, and a part of the peripheral end face in the frame and the end face of the glass plate 7 are provided. If joined by the structural sealing material 8 and provided with fasteners (not shown) on the inner side surfaces of the vertical frames 3 and 4, they serve as an example of an exterior panel, both of which effectively bear a load such as wind pressure.

A wind pressure test was performed on the glass 9 with a frame under the following conditions to obtain a glass plate 7
The stress and the bonding state of the structural sealing material 8 were confirmed.

Glass plate ・ ・ 8mm 1500 × 1500mm square Frame cross section ・ ・ 50 × 50mm square pipe Joint width of sealing material 8 ・ ・ 6mm No groove structure sealing material 8 ・ ・ Toray Dow Corning Silicone Co., Ltd. SE 797 sealant (50% modulus: 4.6Kgf / cm ² ) which is a two-liquid type silicone sealing material manufactured by K.K. ・ Wind pressure load ・ ・ Maximum ± 280Kg / m ² Test result In-plane stress (center of glass plate) 195〜201Kg / cm ² (Allowable value 250Kg / cm ² ) Edge stress (edge) 4 to 13Kg / cm ² (Allowable value 180Kg / cm ² ) Deflection (glass center) 12.5 to 12.8mm (glass edge) 4.0 to 4.3mm Glass plate 7 Is slightly larger than that in the conventional mounting state as shown in FIG. 3, but is within the allowable value, and there is no problem. The deformation amount of the structural sealing material 8 is large in the center but withstands use. No cracks were found, and both honey and airtightness tests passed.

Considering that there is no problem in butt-joining, the glass plate 7 and the aluminum frame body 6 have an integral structure, and since the Young's moduli of glass and aluminum are almost the same, in addition to the frame body 6, the glass plate If the rigidity of the glass plate 7 is also taken into consideration, the cross-sectional shape of the frame body 6 can be made small by taking into account the bending rigidity of the glass plate 7, and the joining of the glass plates 7 shown in FIG. Whereas the wind pressure load of tension / compression acts on the material 8, in the case of butting, the shearing action acts on the structural sealing material 8, and the shear deformation rate is large at the center of the edge span and small at the end. Therefore, a device to reduce the deflection of the glass plate, that is, to use a glass plate 7 that is one rank thicker, or to form a groove 10 at the end of the glass plate 7 and inject and fill the structural sealing material 8 If chemical bonding is performed, the load applied to the structural sealing material 8 on the inclined bonding surface will change from shear to tension or compression, and the amount of deformation will be reduced, or it will become safe by changing to proven tension / compression support, which will result in a false pull. In a window glass such as a door, since it is not necessary to insert the glass plate 7 into the conventional concave cross-section frame body, the assembling portion can be made thin, and the rail groove 1 can be directly formed in the upper frame 2. It is also possible to attach the accessory to the frame body 6 and pull down the window without processing the glass plate 7 itself,
Rotating windows can be easily manufactured.

Even when the framed glass 9 is attached for transportation, the frame 6 is joined to the edge of the glass plate 7 by the structural sealing material 8 so that the edge of the glass 9 is not chipped due to an accident due to collision.

(Effect of the Invention) The glass with a frame according to the present invention has a simple and narrow cross-sectional structure of the frame, reduces the material of the frame, is easy to assemble, and protects the glass edge during transportation and mounting. The effect is remarkable.
