Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for manufacturing a framed glass window, and more particularly, to a sash made of a synthetic resin around a single plate or a double-glazed glass,
The present invention relates to a method for manufacturing a glass window with a frame, wherein a frame such as a gasket, a frame, a frame, a molding, or the like is integrally formed.

[Prior art] Conventionally, single-pane glass, especially net-plated glass or glass having an interlayer film, has excellent fire-resistance, impact-resistance, and shatter-prevention performance, so that a hollow layer can be formed from a plurality of glass plates. The double glazing, which is provided with spacers around the periphery and seals the hollow layer by forming a sealant layer around the periphery, has excellent heat insulation performance, soundproofing performance, and dew condensation prevention performance. It is widely used as glass for windows for vehicles, various devices, showcases and the like, or glass for doors. Such glass is used for windows or doors by attaching several parts for forming a frame such as a sash, gasket, frame, etc. around the glass to complete the frame, and is used for windows or doors. There is a danger that it takes time to mount and assemble, and that water penetrates through the clearance of the mounting portion of the frame, and that the water invades the peripheral portion of the glass, thereby deteriorating the performance of the glass.

Also, frame parts such as sashes, gaskets, frames, etc., for example, parts of each part made of aluminum, plastic, rubber, etc., must be formed in a predetermined shape in advance, and it takes time and effort to manufacture each part. Takes
When the structure of the components of the frame becomes complicated and heavy, the manufacturing cost is further increased, and the cost is further increased.

On the other hand, in a method of integrally molding a synthetic resin frame around the glass, a mold having a predetermined shape is formed around the glass, and a solidified resin or a raw material thereof is injected into the injection space, and the synthetic resin is injected. A method for removing the glass from the mold after solidification is known, but there are great restrictions on the cost of the mold, the production process, the size that can be produced, and the like.

[Problems to be Solved by the Invention] Since the conventional single-paned glass or double-glazed glass has the above-described configuration, it takes time to cure at the time of assembly. Also, at the time of construction, it takes time to push the bead for waterproofing, or even if the method of filling the caulking material on site requires working time and curing time, and it is not perfect in terms of waterproofing, so veneer In particular, the edge of the netted glass sheet is damaged by immersion and rust, and in the case of laminated glass having an interlayer film,
It causes deterioration of the interlayer surface. Further, in the case of a double glazing, when the edge portion is in a high humidity state, the durability of the sealing material and, consequently, the heat insulation of the double glazing are reduced, and the present invention is intended to solve such a drawback. It is assumed that.

[Means for Solving the Problems] The present invention has been made to solve the above-mentioned problems. The gist is to prepare a single-pane glass or a multi-layer glass in which a hollow layer is formed between glass plates by disposing a spacer at the periphery between the glass plates and spaced at predetermined intervals. The extruded synthetic resin frame is heated and softened, and the glass is run toward the synthetic resin frame so that the synthetic resin frame is attached to the peripheral portion of the glass with an adhesive or the like. A method for manufacturing a glass window with a frame, characterized by integrating a frame.

Hereinafter, description will be made in accordance with embodiments of the present invention. Figures 1 and 2
It is a drawing showing a process of assembling a double-glazed glass. First, a spacer 3 is arranged between the peripheral portions of the glass plates 1 and 2 so that the glass plates 1 and 2 are opposed to each other at a predetermined interval substantially in parallel. The multi-layer glass 4 is assembled. In this double-glazed glass, a bonding layer 5 made of an adhesive, an adhesive tape, a sealant, or the like is interposed at least between the inner surfaces of the peripheral portions of the glass plates 1 and 2 and the side surfaces of the spacers 3. Glass plates 1 and 2 and spacer 3
Are not integrated and temporarily fixed. The integration of the crow plates 1 and 2 and the spacer 3 or the temporary fixing by the bonding layer 5 may be omitted in some cases. The example shown in FIG. 1 is an example in which a bead-like sealant 6 is sandwiched between the peripheral portions of the glass plates 1 and 2 and the spacer 3 and pressed to provide a bonding layer 5.

The double-glazed glass assembled in this way is arranged on a predetermined work bench in order to integrate a frame made of synthetic resin around the periphery. The same applies to single-pane glass.

FIG. 3 is a view showing a manufacturing process for integrating a frame of synthetic resin with a peripheral portion of the veneer 1 or the plurality of glasses 4. The primer dropped from the primer reservoir 7 is applied to the glass surface with a roller 8 such as a felt, and dried by a blower 9. In the case of a two-liquid primer, the primer reservoir 10, the roller 11, and the blower After being applied and dried by 12, a synthetic resin frame 13 previously formed by extrusion or the like is softened by a heating blower 14, and is adhered and integrated with a glass peripheral portion by a pressure roller 15. Thereafter, the synthetic resin frame is solidified by the cooling blower 16.

As described above, the frame can be formed around the entire periphery of the glass, and can change the type of glass, whether it is a single plate or a multi-layer glass, or a glass having irregularities on the surface, and a thickness and the like. It is possible to cope with it. On the other hand, it is possible to cope with shapes such as bent glass having a certain degree or more and cubic curved vehicle glass, without being limited by the dimensions such as the width and height of the glass.

As a manufacturing facility, the configuration shown in FIG. 3 is divided into one or a plurality of units to be automated, and a sensor or the like for judging the thickness or the like of an object to which the peripheral frame is mounted is added, and the glass is rotated by a turntable or the like. It is also possible to use a robot, such as molding while performing.

[Function] In the present invention, a frame made of synthetic resin integrated around a single plate or a double-glazed glass is one that has been increased in adhesive strength by primer treatment, softened and pressed by heat treatment, and then cooled and cured. In addition, since the predetermined strength is obtained in a short time, the curing time after casting the structural seal as in the conventional method is not required, and the working time in the assembly process is reduced.

Further, since the edge portion is protected by a frame made of an integrated synthetic resin when transporting the glass, even if the edge portion comes into contact with another member or the like, the edge portion is unlikely to cause damage after a lapse of time due to damage or flooding.

Further, in the case of assembling into a window frame or the like, since a frame made of a synthetic resin also serves as an assembling bead, it is possible to save labor for attaching a bead to the window frame and for pushing down the bead later. In addition, in the case of fixing by caulking or the like at the site, the curing time after filling the caulking material is not required, so that the construction period at the site can be shortened.

Even after assembling into the window frame, even if there is water leakage from the gap of the bead, or the gap of the sash, the glass edge portion is protected by the frame made of the synthetic resin according to the present invention, so it comes into direct contact with water As a result, the durability is improved.

[Example] FIG. 5 is a cross-sectional view when the single-pane glass according to the present invention is incorporated and fixed in a window frame, and FIG. 6 is a cross-sectional view when the double-glazed glass is incorporated and fixed in a window frame. Reference numeral 18 denotes a framed glass according to the present invention, and 20 denotes a window frame. Since the shape of the frame made of the synthetic resin 13 can be made almost freely, the shape of the cross section can be changed by, for example, partially providing a concave portion or a convex portion, and the shape can be adjusted to the window frame.

As the window frame, metals such as aluminum and iron, resins such as PVC, wood, concrete, and ceramic materials are used.

In FIG. 6, the conventional window frame is used as it is, and is fixed by inserting and fitting the framed glass according to the present invention. FIG. 7 shows an example in which the fitting portion is positioned outside the glass. By doing so, the cross section of the window frame can be made smaller, the depth dimension can be reduced, and the multi-layer glass can be stored in the single-pane window frame. Becomes possible. FIG. 8 shows an example in which a plurality of rows of band-shaped portions formed on a frame made of a synthetic resin come into contact with the inside of a window frame portion, whereby airtightness is fixed well.

Further, FIG. 4 shows an example in which a frame is formed around a cubic curved glass, which is seen in glass for vehicles, and is an example in which a free shape can be followed.

[Effect of the Invention] As described above, the present invention can shorten the working time in the assembling process of a single plate or a double glazing, and thus greatly contributes to cost reduction. In addition, since the work can be simplified even in the installation of window frames, etc., the work time at the site can be shortened, and the construction period can be shortened. However, construction can be carried out, and site costs can be reduced. In addition, safety is high because of the framed glass.

In particular, unlike the case where the peripheral frame is integrally molded using a mold, the present invention can cope with any size and shape, and the edge which is a weak point of a single plate or a double glazing having a conventional function. By protecting the part, the effect of reducing loss due to breakage is also recognized.
