JPH0752934Y2 - Double glazing unit - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a double glazing unit in which an adapter is attached to the periphery of double glazing.

[Conventional technology]

As shown in Japanese Utility Model Application Laid-Open No. 60-143876, the peripheral edge of the double-layer glass is fitted into the concave portion of the adapter through a beet, and a vent hole is formed between the beet and the glass surface. There is known a double-glazing unit in which a water drainage hole is formed in the glass so that rainwater mixed between the glass surface and the beet can be drained through the water drainage hole.

[Problems to be solved by the device]

With such a double glazing unit, rainwater that has infiltrated between the glass surface and the beet can be drained, but the beet needs to have a special shape having a recess, resulting in high cost and the bottom wall of the recess of the adapter. Since the end face of the double glazing is abutted via the beet, the gap between the bottom wall of the recess and the end face of the double glazing is narrow, and the beet is in contact with the end face of one glass plate of the double glazing, so that the glass surface The rainwater that has infiltrated into the concave portion between the beet and the beet may infiltrate into the pair of glass plates by a capillary phenomenon from the bonding portion between the sealing material that presses the glass plates together and the back surface of the glass.

Therefore, an object of the present invention is to provide a double glazing unit capable of solving the above-mentioned problems.

[Means and Actions for Solving the Problems]

A ridge is provided on the inner surface of the recess of the adapter, and the end face of the glass plate is pressure-bonded to the upper surface of this ridge by caulking material to fit the double-layer glass into the recess of the adapter, and a drain hole is formed in the horizontal plate of the adapter. It is formed so that rainwater that has entered between the glass plate and the inner surface of the recess can be drained from the drain hole.

〔Example〕

The outer peripheral back surfaces of the pair of glass plates 1 and 1 are adhered to each other with a sealing material 2 to form a double glazing 4 having a hollow portion 3, and an adapter 5 is attached to the rim of the double glazing 4 to form a double glazing unit. .

The adapter 5 has a shape in which one side plate 6 and the other side plate 7 are integrally connected by a connecting plate 8 and has a recess 9 and a leg portion 10. The one side plate 6 and the other side plate 7 are bent in a crank shape to form the recess 9 Has legs
The bent pieces 6a and 7a are wider than 10, and the bent pieces 6a and 7a are closer to the recess 9 than the connecting plate 8, and the protrusions 11 are opposed to each other on the inner surfaces of the one side plate 6 and the outside plate 7 forming the recess 9 in the longitudinal direction. The protrusions 11 are shorter than the thickness of the glass plate 1, and the notches 12 are formed at a plurality of positions in the longitudinal direction of the protrusions 11. A drainage port 13 is formed.

A caulking material 14 having a sealing property and an adhesive property is provided on the upper surface of the ridge 11 of the adapter 5 in the longitudinal direction, and the double-glazing unit 4 is fitted in the recess 9 of the adapter 5 to form a pair of glass plates 1. , 1 end surface is crimped onto the ridge 11 via the caulking material 14 to connect the multilayer glass 4 and the adapter 5, whereby the bottom of the recess 9 of the adapter 5, that is, the bent pieces 6a, 7a. A large drainage space A is formed between the end face of the double-glazed glass 4.

A seal material 15 is attached to the leg portion 10 of the adapter 5, and the seal material 15 is fitted into the recess 17 of the frame 16 so that the leg portion 10 is attached to the frame 16.
The frame 16 is attached to the periphery of the double glazing by being supported by
A drain hole 18 is formed in the sealing material 15.

[Effect of device]

Rainwater that has entered between the glass plate 1 and the adapter 5 is drained from the drain port 13, and since the protrusions 11 are shorter than the thickness of the glass plate 1, the protrusions reach the bonding surface between the glass plate 1 and the sealing material 2. 11 does not project, rainwater does not flow to the adhesive surface by striking the ridges 11, and rainwater does not enter the inside of the double-glazed glass 4 by a capillary phenomenon.

Further, since the double glazing 4 is directly fitted into the concave portion 9 of the adapter 5, the beat is not necessary and the cost can be reduced accordingly.
