Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing double glazing.

Conventionally, various methods for manufacturing this type of double-glazed glass have been proposed.

For example, spacers are connected in a rectangular shape via a corner block, a desiccant is placed inside each spacer, a pair of glass is adhesively fixed to both end surfaces of the spacer, and then the area between the pair of glasses is sealed. A manufacturing method is known in which the material is filled with an agent.

However, in this manufacturing method, the desiccant material is inserted in the longitudinal direction, which makes the operation very troublesome.

Moreover, if there is a dimensional error or a connection error in each spacer, the pair of glasses cannot be connected in parallel, resulting in distortion.

The present invention was made in view of the above-mentioned circumstances, and its purpose is to provide a method for manufacturing double-glazed glass in which a desiccant can be easily added.

Embodiments of the present invention will be described below with reference to the drawings.

First, as shown in Fig. 1, a bottom wall 1, both side walls 2,
Notches 4 ₁ , 4 ₂ , 4 ₃ are formed at predetermined intervals in the longitudinal direction on both side walls 2 , 2 of the elongated material 3 having a U-shaped cross section.

Then, the elongated material 3 is bent from each notch 4 to form a rectangular spacer frame 5 as shown in FIG.

A plurality of small holes 6 serving as ventilation holes are formed in the bottom wall 1 at intervals in the longitudinal direction.

Then, as shown in FIG. 3, a pair of glasses 6 ₁ and 6 2 are adhesively fixed to both side walls 2 and ₂ of the spacer frame 5 using an adhesive 7. At this time a pair of glasses 6
The ends of ₁ and 6 ₂ extend outward from the ends of both side walls 2 and 2.

After this, as shown in FIG. 4, a breathable cylindrical pouch 9 filled with a desiccant 10 is inserted into a concave portion 8 opened outward by the bottom wall 1 and both side walls 2, 2. do.

At the same time, resilient shielding plates 11 made of synthetic resin or the like are sequentially fitted into the recessed portion 8 to shield the opening 8a, and the pouch 9 is attached to the bottom wall 1 and both side walls 2, 2. to force.

That is, as shown in FIG. 5, the shielding plate 11 is bent into a substantially doglegged shape and pushed into the recessed part 8 through the opening 8a, and the elastic force of the shielding plate 11 restores it to the straight state. , 2 are fitted into each concave portion 8.

Thereafter, covers 12 as shown in FIG. 6 are provided between the end faces of the adjacent side walls 2, 2, respectively.

In other words, the cover 12 has a shape in which a pair of side walls 13, 13 forming a right triangle are connected by a connecting wall 14, and as shown in FIG. wall 2,
2 and covers the pouch 9 exposed at the corner portion.

Then, as shown in FIG. 8, a pair of glasses 6
Apply sealant 1 over the entire area between the peripheral edges of ₁ , 6 _{and 2.}
Fill 5.

At this time, the sealant 1 is removed by the shielding plate 11.
5 and the pouch 9 are prevented from coming into contact with each other, and the desiccant 10 is prevented from being affected by the sealant 15.

As described above, since the desiccant 10 is placed in the concave portion 8 having the opening 8a on the outside of the spacer frame 5, the desiccant 10 can be placed easily.

Further, since the desiccant 10 is pressed into the recessed portion 8 by the shielding plate 11, the desiccant 10 can be reliably held within the spacer frame 5.

Further, the desiccant 10 is placed in the pouch 9, and the shielding plates 11 can be sequentially fitted at the same time as the pouch 9 is placed in the recess 8. Therefore, the desiccant 10 can be smoothly and continuously attached to the spacer frame 5 without scattering. In addition to being able to put it inside, the work is extremely easy.

Further, the desiccant 10 can be replaced by removing the sealing agent 15, removing the shielding plate 11, and leaving the glass plates 6 ₁ and 6 ₂ and the spacer frame 5 still joined.

Incidentally, the shielding plate 11 may be fitted into the concave portion 8 in a substantially doglegged shape as shown in FIG.

In addition, as shown in FIG. 10, the tips 2', 2' of both side walls 2, 2 are made longer than necessary and thinner to make them easier to bend, and the tips 2', 2' are bent and overlapped. The opening 8a may be closed. Note that notches may be formed to make it easier to bend the tip portions 2', 2'.

In other words, the tip portions 2', 2' serve as the shielding plates 11.

Further, as shown in FIG. 11, a desiccant 10 is filled in a metal or resin holder 20, and the tip 20a of this holder 20 is fitted into the recess 8 through the opening 8a and fixed. Also good.

Alternatively, the desiccant 10 may be placed directly into the recess 8 and the opening 8a may be closed with the shielding plate 11.

Since the method for producing double-glazed glass according to the present invention is as described above, the desiccant 10 can be easily added, and since the desiccant 10 and the sealant 15 do not come into contact with each other, the desiccant 10 is the same as the sealant 15. unaffected.
