Description

Technical Field

[0001] The utility model relates to the technical field of thermally-insulated aluminum doors and windows, and in particular to a heat-insulating strip and an integrated window structure. Background Art

[0002] Thermal break aluminum doors and windows use thermal break aluminum profiles and hollow glass, which have the functions of energy saving, sound insulation, noise prevention, dust prevention, waterproofing, etc. There are two main ways to produce thermal break profiles. One is to use thermal break strip materials and aluminum profiles to form a "thermal break bridge" through mechanical toothing, strip insertion, rolling and other processes, which is called thermal break profile "strip insertion type"; the other is to pour the thermal break material into the thermal break cavity of the aluminum alloy profile, and after curing, remove the thermal break metal and other processes to form a "thermal break bridge", which is called "casting type" thermal break profile.

[0003] Usually, strip-type insulation profiles are more commonly used, among which the insulation strips between the profiles on both sides determine the thermal insulation performance of the window. Generally, the thicker the insulation strips, the more cavities there are, and the better the thermal insulation performance. However, in order to control the overall thickness of the window, the size ratio of the insulation strips of the triple-glazed window and the aluminum profiles on the left and right sides is usually a:1:1, where a<1. For some double-glazed integrated windows, the width ratio of the insulation strips is even lower. Therefore, it is difficult to ensure good thermal insulation effects. Summary of the invention

[0014] Preferably, reinforcing ribs are provided in the third heat-insulating cavity, and the reinforcing ribs are arranged obliquely, and the inclination directions of the reinforcing ribs in the third heat-insulating cavities adjacent to each other are different.

[0028] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0029]

Integrated form structure

[0030] Combination Figure 1-2As shown, the utility model proposes an integrated window structure, including a first profile 10, a second profile 20, and a heat insulation structure connected between the first profile 10 and the second profile 20. Among them, the first profile 10 and the second profile 20 are aluminum profiles, and the heat insulation structure is mainly made of nylon material with poor thermal conductivity. It can be understood that when the gap between the first profile 10 and the second profile 20 is smaller, the heat is easily transferred from the first profile 10 or the second profile 20 to the other side, and when the gap between the first profile 10 and the second profile 20 is larger, it is not easy to achieve heat conduction between the first profile 10 and the second profile 20.

[0031] Therefore, in order to increase the thermal insulation of the window structure, the present application aims to increase the width of the thermal insulation structure, the first profile 10 includes a first supporting portion 11 and a first connecting portion 12, and the second profile 20 includes a second supporting portion 21 and a second connecting portion 22. By adding the connecting portion, the width of the supporting portion is reduced to increase the accommodation space of the thermal insulation structure.

[0032] In an optional embodiment, the first connecting portion 12 is constructed into a C shape, including an upper connecting arm 121 and a lower connecting arm 123, and a first space 124 for accommodating a heat insulation structure is formed between the upper connecting arm 121 and the lower connecting arm 123, and the width of the first space 124 is more than one half of the width of the first profile 10, and the second connecting portion 22 is constructed to be axially symmetrical with the first connecting portion 12.

[0033] The second connection part 22 is constructed in the same structure as the first connection part and is arranged symmetrically with a heat insulation structure.

[0034] In this way, by constructing a C-shaped connection structure, a first space 124 is added to the first profile or the second profile, so that the width of the thermal insulation structure is more than doubled, which can effectively improve the thermal insulation performance of the window structure.

[0035] Combination Figure 1As shown, a first extended support structure 14 is provided above the first support portion 11, a first bearing area 13 is provided above the first connecting portion 12, a second extended support structure 24 is provided above the second support portion 21, and a second bearing area 23 is provided above the second connecting portion 22. The first connecting portion 12 of the first profile 10 and the second connecting portion 22 of the second profile 20 face the direction of the heat insulation structure, and a cushion body of multi-layer glass 70 is provided between the first bearing area 13 and the second bearing area 23, wherein the cushion body includes a rubber pad 50 and a sealant layer 60 wrapped around the bottom of the glass, and the multi-layer glass 70 is arranged in a sealing structure connection between the first extended support structure 14 and the second extended support structure 24, the first extended support structure 14 can be sealed and connected to one side of the multi-layer glass 70 through the sealing structure, and the first connecting portion 12 can be sealed and connected to the other side of the multi-layer glass 70 through the sealing structure.

[0036] Optionally, the multi-layer glass 70 is double-layer glass, especially a double-layer glass integrated window structure. The distance between the first profile 10 and the second profile 20 used in the double-layer glass is small, which is not conducive to heat preservation. The present application increases the heat preservation by increasing the width of the insulation structure.

[0037] Combination Figure 2 As shown, at the B height layer, the heat conduction path is the multi-layer glass 70, and the multi-layer glass 70 can adopt a hollow or laminated glass structure. At the A height layer, the heat conduction path is the second profile 20-insulating structure-first profile 10. Since the first profile 10 and the second profile 20 are aluminum profiles with good heat conduction capabilities, the second profile 20 and the first profile 10 are effectively isolated to reduce the transfer of heat at the A height layer.

[0038]

Thermal insulation strip

[0039] Optionally, the thermal insulation structure includes a thermal insulation profile 30 and a supporting profile 40 , the thermal insulation profile 30 includes a third connecting portion 31 and an extending portion 32 , the third connecting portion 31 is connected to the upper connecting arm 121 and the lower connecting arm 123 , and the extending portion 32 fills the first space 124 .

[0040] Combination Figure 2 As shown, the third connecting portion 31 of the thermal insulation profile 30 is located at the gap between the first profile 10 and the second profile 20, and the extending portion 32 of the thermal insulation profile 30 extends to the first profile 10 and the first space 124 on one side of the second profile 20. It is easy to understand that the heat conduction from the first profile 10 to the second profile 20 is divided into three areas, the first is the upper connecting arm 121 area, the second is the area between the upper connecting arm 121 and the lower connecting arm 123, and the third is the lower connecting arm 123 area.

[0041] Optionally, the heat insulating profile 30 is made of nylon.

[0042] For the first area, the thermal insulation profile 30 must complete the connection and also have good thermal insulation properties, which is achieved by constructing a cavity in the thermal insulation profile 30. For the second area, it is necessary to ensure good thermal insulation and reliable support capabilities, which is achieved by constructing multiple cavities in the thermal insulation profile 30 and filling them with supporting structures. For the third area, it is the same as the first area, and is achieved by constructing a cavity in the thermal insulation profile 30.

[0043] In a specific embodiment, in combination Figure 2 and Figure 4 As shown, the third connecting portion 31 is configured as a strip structure, and the upper and lower portions of the third connecting portion 31 are respectively provided with snap-fit ​​structures 311 corresponding to the upper connecting arm 121 and the lower connecting arm 123 .

[0044] The ends of the upper connecting arm 121 and the lower connecting arm 123 are provided with narrowed grooves, such as dovetail grooves or arc grooves, and the clamping structure 311 can be clamped into the grooves at the ends of the upper connecting arm 121 and the lower connecting arm 123 .

[0045] Preferably, a second heat insulating cavity 312 is provided between the two clamping structures 311 at the upper and lower parts of the third connecting part 31. The design of the second heat insulating cavity 312 can reduce the heat transfer area along the cross-sectional direction of the third connecting part 31 and increase the heat transfer path.

[0046] Furthermore, a second space 313 is provided inside the third connecting portion 31 , and the supporting profile 40 is filled in the second space 313 , so that the strength of the thermal insulation profile 30 is enhanced by the supporting profile 40 , especially the compression and torsion resistance.

[0047] Optionally, the width of the second space 313 is the same as the width of the shorter distance between the two upper connecting arms 121 or the two lower connecting arms 123 , and the height of the second space 313 is the same as the height difference between the upper connecting arm 121 and the lower connecting arm 123 .

[0048] In this way, by filling the large-sized supporting profile 40, the thermal insulation profile 30 as a whole is not easy to deform and has a strong supporting capacity.

[0049] Preferably, Figure 2 As shown, the support profile 40 is configured as a strip structure, the cross-sectional shape of the support profile 40 is rectangular, and a reinforcing plate 42 is provided inside the support profile 40 and cross-distributed along the diagonal line, and a first heat-insulating cavity 43 is formed inside the support profile 40. Optionally, the support profile 40 is made of plastic steel. The support profile 40 of such a shape can achieve good compressive resistance, and at the same time, the heat transfer capacity along the radial direction of the profile is low, so as to ensure the overall heat insulation performance of the heat-insulating profile 30.

[0050] Combination Figure 4 As shown, the extension part 32 of the heat insulating profile 30 is provided with a third heat insulating cavity 321, and along the cross-sectional direction of the heat insulating profile 30, the third heat insulating cavity 321 occupies more than 70% of the cross-sectional area of ​​the extension part 32. By constructing a large-area third heat insulating cavity 321 on the extension part 32, multiple independent air cavities exist in the heat transfer path, so that the heat is absorbed by the multiple air cavities, delaying the heat transfer, and achieving the purpose of heat preservation and heat insulation.

[0051] Further, combined with Figure 3 As shown, the first support part 11 and the second support part 21 are both constructed to include an inner support wall 111 and an outer support wall 112 . The inner wall of the inner support wall 111 is provided with a support plate 122 extending toward the first space 124 , and the extension part 32 is provided with a groove 323 corresponding to the support plate 122 .

[0052] In this way, the thermal insulation profile 30 is easily assembled between the first profile 10 and the second profile 20, and the support plate 122 supports and positions the thermal insulation profile 30. The thermal insulation profile 30 is not easily displaced, thereby ensuring the sealing between the first profile 10 and the second profile 20 and avoiding the formation of a direct airflow channel between the first profile 10 and the second profile 20.

[0053] Preferably, the support plate 122 is disposed between two third heat insulation cavities 321 .

[0054] Furthermore, in order to increase the compressive strength of the heat insulating profile 30 , a reinforcing rib 322 is provided in the third heat insulating cavity 321 , and the reinforcing rib 322 is arranged obliquely.

[0055] like Figure 4 As shown, preferably, along the cross-sectional direction of the thermal insulation profile 30 , the reinforcing ribs 322 are distributed in a zigzag shape, and the first end of the reinforcing rib 322 is close to the upper connecting arm 121 , and the second end is close to the lower connecting arm 123 .

[0056] Taking the extension part 32 on the left side of the third connecting part 31 as an example, in the top third insulating cavity 321, the reinforcing rib 322 is inclined from near the end of the upper connecting arm 121 toward the first support plate 122, in the middle third insulating cavity 321, the reinforcing rib 322 is inclined from the first support plate 122 to the direction away from the second support plate 122, and in the bottom third insulating cavity 321, the reinforcing rib 322 is inclined from the direction away from the second support plate 122 to the end of the lower connecting arm 123. The three reinforcing ribs 322 form a zigzag shape, which on the one hand increases the structural strength of the extension part 32, and on the other hand makes the cavities of the extension part 32 become more and more independent, so that the heat transfer path is more dispersed and the heat storage area is more, thereby achieving the purpose of enhancing thermal insulation.

[0057] In combination with the above embodiments, the thermal insulation strip provided in the present application includes a connecting part and an extending part, and has a part extending to the first profile and the second profile area. When the spacing between the first profile and the second profile remains unchanged, the thickness of the thermal insulation structure is increased. The thermal insulation structure adopts a composite method of thermal insulation profiles and supporting profiles. The thermal insulation effect is improved by constructing a wide-spacing, multi-cavity thermal insulation structure. At the same time, the strength of the thermal insulation structure is made higher by utilizing the strength of the reinforcing ribs and the supporting profiles, especially when the total width of the first profile and the second profile is small, a better thermal insulation effect can be achieved.

[0058] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
