Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for manufacturing double glazing, and more specifically, a method for manufacturing double glazing, and more specifically, a method for producing double glazed glass, and more specifically, a method for producing double glazed glass, and more specifically, a method for producing double glazed glass, in which a pair of glass plates facing each other are arranged with a spacer interposed therebetween so that the two glass plates are separated from each other. The present invention relates to a method for producing double-glazed glass.

Generally, with this type of double glazing, it is difficult to remove the fog from the glass panes if moisture gets inside the glass panes, so make sure to keep the space between the two glass panes airtight to prevent moisture from getting inside. are connected to each other. Conventionally, in order to maintain this airtightness, a sealing material 4' made of butyl rubber has been filled between the spacer 3 and the glass plates 1a and 1b, as shown in FIG. However, in order to obtain sufficient airtightness with this type of sealing material 4', it is necessary to apply the sealing material 4' many times, which is a time-consuming process.

The present invention has been made to eliminate the above-mentioned conventional drawbacks, and its main purpose is to provide a method for manufacturing double-glazed glass that is easy to manufacture and provides sufficient airtightness. It's about doing.

Embodiments of the present invention will be described below based on the drawings. In the method for manufacturing double-glazed glass according to the present invention, grooves 2 extending over the entire length in the longitudinal direction are formed between a pair of glass plates 1a and 1b that are arranged opposite to each other on the surface facing the glass plates 1a and 1b. It is a tube with a spacer 3 interposed therebetween and a sealing material 4 made of butyl rubber filled inside.
A sealing tube 6 having a plurality of through holes 5 through which water can flow out is fitted over the entire longitudinal length of the groove 2, and then the glass plates 1a and 1b are pressed against the spacer 3, and the sealing material 4 is poured from inside the sealing tube 6.
Spacer 3 and glass plate 1
a and 1b are hermetically coupled. As shown in FIGS. 2 and 3, the spacer 3 is a hollow body with a rectangular cross section made of aluminum or the like, and grooves 2 extending over the entire length in the longitudinal direction are formed on both upper and lower surfaces of the spacer 3, respectively. This groove 2
A sealing tube 6 is fitted into the groove 2 over the entire length thereof in the longitudinal direction. The sealing tube 6 is made of a material that can be easily deformed, and is filled with a fluid sealing material 4 made of butyl rubber. A through hole 5 is formed. Although the through holes 5 are shown arranged in one row in the figure, it goes without saying that they may be provided in multiple rows. The through hole 5 communicates with the inside and outside of the sealing tube 6, and when the sealing tube 6 is deformed, the sealing material 4 inside seeps out through the through hole 5.
The outer diameter of this sealing tube 6 is the spacer 3
The depth of the sealing tube 6 is larger than the depth of the groove 2, and a portion of the sealing tube 6 protrudes from the groove 2 when the sealing tube 6 is fitted into the groove 2. In this state, when the peripheral edges of the glass plates 1a and 1b are pressed against the spacer 3 while pressing down on the sealing tube 6, the sealing tube 6 deforms and the sealing material 4 seeps out from inside through the through hole 5. A sealing material 4 is interposed between the glass plates 1a, 1b and the spacer 3. As a result, the glass plates 1a, 1b and the spacer 3 are hermetically coupled, and the positional relationship between the glass plates 1a, 1b is fixed. Here, the sealing tube 6 is connected to the concave groove 2.
By being housed in the glass plate 1a,
There is only a distance corresponding to the sealing material 4 between 1b and the spacer 3, and the use of the sealing tube 6 does not make the product thicker than before. To further improve airtightness,
A sealing material 8 such as thiocol may be interposed between the glass plates 1a and 1b on the outer peripheral side of the spacer 3.
Further, a desiccant may be placed inside the spacer 3.

As described above, the present invention includes a spacer interposed between a pair of glass plates, each having a concave groove on the surface facing the glass plate, and a through-hole that is filled with a sealant and allows the sealant to seep out. The sealing tube formed with this is fitted over the entire length in the longitudinal direction of the concave groove, and then the glass plate is pressed into contact with the spacer to form a sealing tube and allow the sealing material to seep out, making the spacer and glass plate airtight. Since the sealing material is directly connected between the spacer and the glass plate, there is no need to apply the sealing material between the spacer and the glass plate, and it is sufficient to simply fit the sealing tube into the concave groove. As a result, there is an advantage that manufacturing work is simplified. Furthermore, by fitting the sealing tube into the groove, the sealing tube can be positioned, and the sealing material can be filled in a fixed position, thereby stabilizing the quality of the product.
