Description

Technical Field

[0001] The utility model relates to the technical field of glass curtain walls, in particular to a double-insulated glass hidden-frame glass curtain wall structure. Background Art

[0002] Most of the insulating glass commonly used in glass curtain walls is double-layer glass with a single air cavity between them. In the case of double-insulated glass, there are two air cavities between three layers of glass, which has better energy-saving and sound-insulating effects, but it is also heavier.

[0003] When connecting the insulating glass to the curtain wall keel in a hidden-frame glass curtain wall, the traditional method is to set an aluminum alloy glass sub-frame between the insulating glass and the curtain wall keel. The aluminum alloy glass sub-frame is fixed to the curtain wall keel by screws, and the insulating glass is fixed to the aluminum alloy glass sub-frame by structural adhesive. When the insulating glass uses heavier double-insulated glass, there may be problems with unreasonable structural stress, or the double-insulated glass panel may fall off due to the failure of the structural adhesive, resulting in unreliable connection. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a double-insulated glass hidden-frame glass curtain wall structure, which can solve the problem that it is not suitable to use an aluminum alloy glass sub-frame connection when the hidden-frame glass curtain wall uses double-insulated glass.

[0005] To this end, the utility model adopts the following technical solutions:

[0006] A double-insulated glass hidden-frame glass curtain wall structure includes a pressing block fixedly connected to the curtain wall keel by screws at one end, and also includes double-insulated glass. A connecting plate is provided at one end of the pressing block for connecting the insulating glass. A groove for inserting the connecting plate is provided on the side of the double-insulated glass. A concave connecting piece is provided in the groove. There are three layers of glass in the thickness direction of the double-insulated glass. The three layers of glass are the first glass, the second glass, and the third glass in sequence from the outdoor side to the indoor side. The groove coincides with the position of the second glass in the thickness direction of the double-insulated glass. The size of the second glass is smaller than that of the first glass and the third glass.

[0007] On the basis of adopting the above technical solutions, the utility model can also adopt the following further technical solutions, or use a combination of these further technical solutions:

[0008] An air cavity is provided between the first glass and the second glass, and between the second glass and the third glass respectively. The periphery of the air cavity is filled with a first sealant. The first sealant is distributed between the first glass and the third glass and covers the side surface of the second glass.

[0009] The connecting member is fixed within the first sealant.

[0010] The groove is located between the first glass and the second glass and is closer to the first glass.

[0011] A foam strip and a second sealant are filled between two adjacent double insulating glasses. The second sealant is located between two first glasses, and the foam strip is fixed to the indoor side of the second sealant.

[0012] The connecting member is made of stainless steel or aluminum alloy.

[0013] The connecting member is arranged longitudinally or in sections along the side length direction of the double insulating glass.

[0014] The groove is arranged longitudinally along the side length direction of the double insulating glass.

[0015] Compared with the prior art, the present utility model has the following advantages and beneficial effects: removing the aluminum alloy glass sub-frame saves costs; among the three glasses of the double insulating glass, the size of the second glass in the middle position is reduced for arranging the groove and installing the connecting member. The double insulating glass is hung on the connecting plate of the pressing block fixed to the keel through this connecting member, and the structure is more reasonably stressed, avoiding the glass panel falling off due to the failure of the structural adhesive; the first sealant filled around the middle air cavity is distributed between the first glass and the third glass and simultaneously covers the side surface of the second glass, with better airtightness and basically avoiding the risk of air leakage in the middle air cavity.

A groove 3 for inserting the connecting plate 11 is provided on the side surface of the double-insulated glass 2. A concave connecting member 5 is provided in the groove 3. Three layers of glass are provided in the thickness direction of the double-insulated glass 2. The three layers of glass are, in the direction from the outside to the inside of the room, a first glass 21, a second glass 22, and a third glass 23 in sequence. The groove 3 coincides with the position of the second glass 22 in the thickness direction of the double-insulated glass 2. The size of the second glass 22 is smaller than that of the first glass 21 and the third glass 23.

[0021] An air cavity 8 is respectively provided between the first glass 21 and the second glass 22, and between the second glass 22 and the third glass 23. The periphery of the air cavity 8 is filled with a first sealant 4. The first sealant 4 is distributed between the first glass 21 and the third glass 23 and covers the side surface of the second glass 22, so that the airtightness of the air cavity 8 is better, and the risk of air leakage in the air cavity is basically avoided.

[0022] The connecting member 5 is fixed in the first sealant 4.

[0023] The groove 3 is located between the first glass 21 and the second glass 22 and is closer to the first glass 21, so that the thickness of the part of the first sealant 4 between the groove 3 and the third glass 23 is thicker, while the thickness of the part of the first sealant 4 between the groove 3 and the first glass 21 is thinner and can meet the design calculation and specification requirements during actual construction, and the structure is more reasonably stressed.

[0024] A foam strip 6 and a second sealant 7 are filled between adjacent two double-insulated glasses 3. The second sealant 7 is located between two first glasses 21. The foam strip 6 is fixed on the indoor side of the second sealant 7. This practice is a common practice when connecting curtain wall glasses and will not be elaborated here.

[0025] In this embodiment, the connecting member 5 is made of stainless steel or aluminum alloy.
