Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a double-glazed glass shoji that can improve an existing single-paned glass shoji, in which a single sheet of glass is already fitted into a window frame of aluminum fittings, into a three-layer or two-layer shoji by a simple method. Regarding shoji.

Double-glazed shoji has much better heat insulation and sound insulation effects than ordinary single-pane glass shoji. Therefore, if it is used in openings in buildings, it will not only prevent condensation in cold regions during the winter by improving the insulation effect, but it will also significantly reduce heating and cooling costs, contributing to the energy conservation that is currently being talked about. obtain. In addition, the improved sound insulation effect can create a comfortable indoor environment by insulating noise from inside and outside the room.

However, when this is used by being fitted inside an aluminum sash window frame, the cross-sectional area of the frame member and packing material becomes large. Therefore, the expected size of the aluminum sash window sill that houses this becomes large, and the sash price becomes extremely high. Furthermore, in general wooden houses, factories, offices, etc., the expected dimensions and fit of frame members and shoji screens are limited by the thickness of the walls, etc., and there is a problem that they cannot be easily installed.

The present invention has been made in view of the above points, and it is possible to easily improve the existing single-pane glass shoji into a double-glazed structure, and also to create an airtight space between the auxiliary glass and the existing plate glass. The first purpose is to provide a double-glazed shoji with a structure that has excellent heat insulation and sound insulation properties, and uses fasteners to hold the auxiliary glass from the gap between the auxiliary glass and the existing plate glass. The second purpose is to provide a double-layer glass shoji that can form a vacuum layer by removing air, and the second purpose is to provide a double-layer glass shoji that can seal dry air, inert gas, etc. into the vacuum gap. The fourth object is to provide a double-glazed shoji that can keep the gap between the existing plate glass and the auxiliary glass airtight by using a spacer to maintain a constant distance between the existing plate glass and the auxiliary glass, The fifth purpose is to provide a double-glazed shoji that can maintain even better airtightness in the gap by using a sealing material. A sixth object of the present invention is to provide a double-glazed shoji that can protect materials such as UV rays from ultraviolet rays.

Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings. Figure 1 shows a perspective view of a double-layer glass assembly with a two-layer structure assembled using existing plate glass 2 fitted into a window frame 1 of aluminum fittings, and Figure 5 shows a double-layer glass with a three-layer structure. A perspective view of the glass assembly is shown.

Apply strong adhesive (epoxy) to the bottom of the large-diameter side of one or more fasteners 5 on the upper side of the existing plate glass 2 fitted into the window frame 1 at a position determined by a jig. system) 12 to completely attach it and fix the fastening tool 5. Of course, before performing these operations, the surface of the existing plate glass 2 is washed and dried.

As shown in Fig. 3, the fastening tool 5 has a substantially cylindrical shape, and the base has a large diameter and also serves as a spacer, and the center pipe 14 at the tip has a small diameter and has a thread machined on the outer peripheral surface. The opening of the center pipe 14 communicates with an air vent hole 19 on the circumferential surface of the base, and a stopper 8 made of a soft material such as soft rubber is fitted into the tip of the center pipe 14.

The same number of fastening tools 5 as the fastening tools 5 are placed on the upper side of the auxiliary glass 3, which has been cut to be one size smaller than the existing glass sheet 2, at positions that match the positions of the fastening tools 5 fixed to the existing glass sheet 2 using a jig. A through hole 6 is made larger than the tip on the small diameter side. A spacer 9 made of metal or synthetic resin, coated with adhesive butyl rubber 13 on both sides, and having a desiccant 16 inside is adhered to the inner peripheral edge of the auxiliary glass 3 on one side in a contour shape,
To make handling easier, a release paper is pasted on the opposite side of the adhesive. Furthermore, in order to improve the aesthetic sense when the auxiliary glass 3 is attached to the existing plate glass 2 and to protect the sealant 10, an adhesive is applied to the inner surface of the decorative picture frame 11, which is made of metal and has an approximately L-shaped cross section. Adhesive fixation is performed on the outer periphery of the outer surface of the glass 3 in the shape of a frame. By the above procedure, the through hole 6 of the prepared auxiliary glass 3 is suspended from both sides of the center pipe 14 at the tip of the fixing device 5 fixed to the existing plate glass 2 via the gaskets 15, so that the auxiliary glass 3 is held by the fixing tool 5, the release paper pasted on the butyl rubber 13 surface of the spacer 9 is removed, and pressure bonding is performed so that the auxiliary glass 3 is evenly adhered to the two existing glass plate surfaces. A gap 4 created between the auxiliary glass 3 and the window frame 1, and further between the auxiliary glass 3 and the existing plate glass 2, is sealed, filled, and filled with a highly elastic sealing material 10 as an adhesive. Sealing material 1
During the curing progress time of 0, the fixing tool 5 fixed to the existing plate glass 2 holds the auxiliary glass 3 fixed through the through hole 6 of the auxiliary glass 3, so that the auxiliary glass does not shift its position during the bonding time. Moreover, since the attachment to the glass plate is performed using an adhesive and a fastening tool, the attachment strength of the auxiliary glass is also improved. Furthermore, since the fastening tool has a large diameter portion formed at the base to be bonded to the glass plate, when the auxiliary glass is bonded, the large diameter base is interposed between the auxiliary glass and the plate glass. Therefore, a certain gap is created between the existing plate glass and the auxiliary glass at the same time as the installation, creating a sealed space. Sealing material 10
As the curing time progresses, the sealing adhesive strength increases. After the sealing material 10 has hardened for a certain period of time, an airtightness check is performed, and an industrial injection needle (large diameter) is inserted into the soft material stopper 8 filled in the center pipe 14 of the fastener 5, and the injection needle and vacuum pump are inserted. Connected to the conduit, the air present in the sealed gap 4 between the existing glass sheet 2 and the auxiliary glass 3 is discharged through the syringe needle to the vacuum pump. Since the gap 4 between the plate glass 2 and the auxiliary glass 3 can be evacuated via the fixing device 5 in this way, the work to evacuate the gap from the surface side of the auxiliary glass can be performed. Even after the double-glazed shoji is fitted into the window frame, work can be easily performed from the front side of the auxiliary glass. The evacuated gap 4 has better heat insulation and sound insulation effects than conventional double glazing. If further heat insulation and sound insulation effects are required, as shown in Fig. 5, auxiliary glass 3 is further attached to both sides of the glass plate 2 in the manner described above, centering on the existing glass plate 2, thereby forming three glass layers. This can be solved by doing this. After the air in the gap 4 has been expelled, when the injection needle is removed from the stopper 8, the contraction force of the stopper 8 seals the needle hole of the injection needle. To further improve the sealing condition, apply adhesive to the needle hole to achieve a more complete seal. By tightening the cap nut 7 to the tip of the fixing tool 5 after ejection in a cap-like manner via a metal washer, the auxiliary glass 3 is more strongly held against the existing plate glass 2 with a fixed space sealed in between. be done. As a final finish, corner decorations 18 are pasted with adhesive as protective covering materials at the four corners of a metal decorative frame 11 adhesively fixed to the outer periphery of the outer surface of the auxiliary glass 3 in the shape of a frame.

If there is a handle 20, the decorative frame 11 is bent along the handle 20 as shown in FIG.

Moreover, after the gap 4 between the auxiliary glass 3 and the existing plate glass 2 is made into a vacuum state as described above,
An inert gas such as neon gas or argon gas, dry air, or the like may be filled into the gap 4 using a syringe needle.

To check the airtightness, it is best to apply soapy water to the gap and use a syringe needle to blow air into the gap 4 from the fastener 5. If air is leaking, bubbles will appear, so you can check this.

What is shown in FIGS. 6 and 7 is still another example of the present invention, in which an auxiliary glass 3 is attached to an existing glass plate 2 fitted in a window frame 1 using a spacer 9 made of metal or synthetic resin. It is something that

As described above, the present invention creates a double-glazed structure by attaching auxiliary glass in parallel to one or both sides of an existing plate glass fitted into a window frame, and makes the gap between the existing plate glass and the auxiliary glass airtight. Because of this, existing single-pane glass shoji can be easily upgraded to double-pane glass shoji, and since the gap between the auxiliary glass and the existing glass is airtight, it has excellent heat and sound insulation properties. Of course, it is excellent for attaching the large diameter side base of the fastening tool to the surface of the existing plate glass, and inserting the small diameter side tip of the fastening tool into the through hole drilled in the auxiliary glass. The auxiliary glass is held by screwing a cap nut onto the tip of the fastener from the outside, so when bonding the existing plate glass and the auxiliary glass with an adhesive such as a sealant, the adhesive During the curing process, the fixing tool fixed to the existing plate glass holds the auxiliary glass fixed through the through hole of the auxiliary glass, which prevents the auxiliary glass from shifting its position during the bonding time. It is possible to
Since attachment to the glass plate is performed using an adhesive and fasteners, the attachment strength of the auxiliary glass is also improved. Furthermore, since the fastening tool has a large diameter portion formed at the base to be bonded to the glass plate, when the auxiliary glass is bonded, the large diameter base is interposed between the auxiliary glass and the plate glass. Therefore, a certain gap must be provided between the existing plate glass and the auxiliary glass at the same time as they are installed. Furthermore, the fastening tool is formed hollow and communicates the inner and outer surfaces of the auxiliary glass with the fastening tool, and a soft plug is inserted into the fastening tool, so that the hardening of the sealing material is constant. After an hour, check the airtightness, insert an industrial syringe needle into the soft stopper fitted into the hollow fastener, connect the syringe needle and vacuum pump conduit, and connect the existing plate glass and auxiliary glass. The gap between the plate glass and the auxiliary glass can be evacuated by discharging the air existing in the sealed gap through the syringe needle and into the vacuum pump, and the gap is evacuated from the surface side of the auxiliary glass. Even after the double-glazed shoji is fitted into the window frame, the work can be done more easily from the front side of the auxiliary glass.
