Description

Technical Field

[0001] This invention relates to the field of passive window and door technology, specifically to a composite passive window and its installation method. Background Technology

[0002] The existing green building and passive building market is developing well. Passive windows will be widely used in such buildings. Thermally broken aluminum alloy windows have the characteristics of material stability, durability and good thermal insulation performance, and occupy an important market share in this market. The commonly used thermally broken aluminum alloy windows on the market need to use the method of widening the spacer and adding thermal insulation filling to improve the thermal insulation performance to meet the requirements of passive windows. However, widening the spacer will increase the stress on the thermal insulation strip, reducing the service life and stability of the entire window. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a composite passive window and its installation method, so as to resolve the contradiction between improved thermal insulation performance and reduced durability and stability of passive thermally broken aluminum alloy windows and doors.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A composite passive window includes a first frame and a third frame, which are connected by a clamping second spacer and a third spacer, with a second thermal insulation filling material between the second and third spacers. A second frame is positioned above the first frame, and a fourth frame is positioned above the third frame, connected by a clamping first spacer and a fourth spacer, with a first thermal insulation filling material between the first and fourth spacers. A first sealing element is provided between the upper outer wall of the first frame and the lower inner wall of the second frame, and a second sealing element is provided between the second and first spacers. A fifth frame is positioned above the fourth frame on the side away from the second frame, forming a glass inlay groove between the fifth frame and the second frame, and inlaying glass therein. An outer frame assembly is also provided on the outer sides of the third, fourth, and fifth frames, with thermal insulation filling material between the outer frame assemblies. The outer frame assembly is connected to the third frame by a fixing component and a limiting component, and is sealed to the fifth frame and the glass by a third sealing element.

[0006] This composite passive window has excellent thermal insulation performance, while ensuring the durability and stability of the door and window, meeting the requirements of passive doors and windows. Moreover, the overall structure is simple and easy to assemble and use.

[0007] This composite passive window blocks the transfer of heat between the interior and exterior by filling the outer frame assembly with thermal insulation material, and forms two thermal insulation lines in the cross-section by keeping the fifth frame non-exposed. This achieves the goal of improving the thermal insulation performance of the aluminum alloy window without changing the width of the spacer strip in the thermally broken aluminum alloy profile, and ensures the durability and stability of the entire window under the new structural system.

[0008] The second and third spacers connect the first and third frames and also form a space to accommodate the second thermal insulation filler. They also serve as the mounting and fixing position for the second seal, forming a sealed and insulating structure with the first spacer. Similarly, the first and fourth spacers connect the second and fourth frames and also form a space to accommodate the first thermal insulation filler. The first thermal insulation filler, the second seal, and the second thermal insulation filler together form a central thermal insulation structure. The flat structure above the fourth spacer can also be used to install and support the glass.

[0009] Furthermore, the outer frame assembly includes a sixth frame and a seventh frame that are fastened together, and the space enclosed by the sixth frame and the seventh frame is filled with the heat insulation filler; the third sealing member is provided at the upper fastening point of the sixth frame and the seventh frame, the fixing component is provided on the side of the seventh frame facing the third frame and connected to the third frame, and the limiting component is provided above the third frame and between the seventh frame and the seventh frame.

[0010] The sixth frame and the seventh frame are connected by snap-fit ​​and filled with heat insulation material in the middle, which can effectively reduce the heat transferred between the indoor and outdoor areas through the frame. The fixing component is used to fix the frame to the third frame, so that the two frames are connected in a linear connection. The limiting component is used to further connect the seventh frame and the third frame, so that the two are connected by a combination of point connection and linear connection, forming a more stable structure.

[0011] Furthermore, the third seal includes an inner snap-fit ​​portion, a hollow elastic sealing portion located on one side of the snap-fit ​​portion, and a free elastic arm on the other side. The snap-fit ​​portion snaps onto a K-shaped snap-fit ​​wall above the fifth frame, the hollow elastic sealing portion abuts against the outer side of the glass, and the free elastic arm is located between the fifth frame and the outer frame assembly.

[0012] The third seal, with this structure, can connect to the fifth frame, form a seal at the connection between the sixth and seventh frames, and also form a seal with the glass, while concealing the entire fifth frame internally. The K-shaped snap-fit ​​wall above the fifth frame effectively secures the third seal, ensuring a stable and reliable connection to the snap-fit ​​portion.

[0013] Furthermore, the fixing component includes an I-shaped connector and a self-tapping screw. The connector engages with a reserved T-shaped groove on the side wall of the seventh frame and its other end abuts against the outer wall of the third frame. The self-tapping screw connects the connector and the third frame. An L-shaped reserved protrusion is also provided above the reserved T-shaped groove, and a fifth sealing element is engaged with the reserved protrusion and the outer wall of the third frame.

[0014] The connector is designed to easily connect with the pre-reserved T-slot and is fixed to the third frame using self-tapping screws. The heads of the self-tapping screws are located inside the connector and are not exposed, thus not affecting the tight connection of adjacent frames. The pre-reserved protrusion allows for easy placement of the fifth sealing element at the connection gap, forming a sealing structure at the joint.

[0015] Furthermore, the limiting component includes an inclined limiting card, one end of which is provided with a folded edge structure, which is connected to the limiting groove of the seventh frame, and the other end of which is provided with a snap-fit ​​structure, which is snapped and fixed in the snap-fit ​​groove above the third frame.

[0016] The limiting card, when inserted into the limiting slots of the third and seventh frames, increases the number of connection points between the third and seventh frames, making the overall structure more stable and ensuring the durability and stability of the entire window. Multiple such limiting cards can be set sequentially at intervals along the length direction, making connection and installation simple and convenient.

[0017] Furthermore, an extension arm is provided below the second frame, and a lateral reserved groove is provided on the inner side of the extension arm. The first sealing member is embedded in the reserved groove, and the free end of the first sealing member abuts against the first frame.

[0018] Furthermore, the second spacer and the third spacer are arranged in parallel, and the inner sides of the second spacer and the third spacer are provided with corresponding baffle structures, and the area between the baffle structures is filled with the second heat insulation filling cotton; the first spacer and the fourth spacer are arranged in parallel, the first spacer is arranged relative to the second spacer, and the first spacer is also provided with a baffle structure above it and the space between it and the fourth spacer is filled with the first heat insulation filling cotton.

[0019] The baffle structure can form a groove between the upper and lower spacers to accommodate the heat insulation filling cotton, ensuring that the heat insulation filling cotton is in the predetermined position for heat insulation and will not loosen or move.

[0020] Furthermore, multiple C-shaped grooves are arranged side by side above the second spacer strip. The C-shaped grooves are used to engage and connect the second seal. The second seal covers the seams on both sides of the second spacer strip that connect to the first frame and the third frame. The top of the second seal abuts against the first spacer strip.

[0021] The second sealing element can be stably connected by multiple C-shaped grooves, forming a long sealing structure that can seal the joints on both sides of the spacer strip and form a spatial sealing structure with the first spacer strip above.

[0022] Furthermore, a glass pad is provided above the fourth spacer, the cross-sectional size of the glass pad is larger than the cross-sectional size of the fourth spacer, and the two sides of the glass pad press against the edges of the second frame and the fifth frame respectively; the glass is provided above the glass pad, the glass is multi-layer hollow tempered glass, a warm edge spacer is provided between the glass, and a fourth sealing element is also snapped between the glass and the second frame.

[0023] Furthermore, a method for installing a composite passive window includes the following steps:

[0024] The first step is to insert the second heat insulation filling cotton into the baffle structure of the second spacer and the third spacer, and then fasten the first frame and the third frame to the second spacer and the third spacer to establish a stable profile structure.

[0025] The second step is to connect the sixth frame and the seventh frame with snap fasteners to form an outer frame assembly with a cavity structure, and fill the sixth frame and the seventh frame with heat insulation filler. After filling, the seventh frame is connected to the third frame with connectors and self-tapping screws to form a double-layer heat insulation frame.

[0026] The third step is to insert several limiting cards between the third frame and the seventh frame and engage them to increase the number of connection points between the third frame and the seventh frame.

[0027] The fourth step is to insert the first heat-insulating filling cotton into the baffle structure of the first spacer strip, and then fasten and connect the second frame and the fourth frame to the first spacer strip and the fourth spacer strip.

[0028] Fifth, install the fourth seal in the gap between the glass and the second frame;

[0029] The sixth step is to fasten the fifth frame to the fourth frame, forming a glass inlay groove between the fifth frame and the second frame and the fourth spacer. A glass pad is placed in the glass inlay groove before the glass is inlaid. Then, the third sealing member is installed in the gap between the glass and the fifth frame.

[0030] Step 7: A second sealing element is embedded above the second spacer strip, and a first sealing element is embedded below the second frame. The outer frame assembly, the third frame, and the first frame are connected to the fifth frame and the second frame to form a double-cavity sealing structure, which can effectively block the exchange of internal and external heat flow and achieve a passive heat insulation effect.

The third and seventh frames are fixed using connectors and self-tapping screws, allowing the two... The frame connection is a linear connection. By inserting the limiting card into the limiting grooves of the third and seventh frames, the number of connection points between the two frames can be increased, making the two a combination of point connection and linear connection, forming a more stable structure and ensuring the durability and stability of the entire window; 4. On the outside of the glass, the first insulation line is composed of the third sealing element, the fifth frame, the seventh frame, and the thermal insulation filler.

[0039] like Figures 1-4As shown, a composite passive window includes a first frame 1 and a third frame 3. The first frame 1 and the third frame 3 are fastened together by clamping a second spacer 14 and a third spacer 15. A second thermal insulation filling cotton 18 is provided between the second spacer 14 and the third spacer 15. A second frame 2 is provided above the first frame 1, and a fourth frame 4 is provided above the third frame 3. The second frame 2 and the fourth frame 4 are fastened together by clamping a first spacer 13 and a fourth spacer 16. A first thermal insulation filling cotton 17 is provided between the first spacer 13 and the fourth spacer 16. The upper outer wall of the first frame 1 is connected to the lower part of the second frame 2. A first sealing element 8 is provided between the inner walls of the square, and a second sealing element 9 is provided between the second spacer 14 and the first spacer 13; a fifth frame 5 is provided above the side of the fourth frame 4 away from the second frame 2, and a glass inlay groove is formed between the fifth frame 5 and the second frame 2 and a glass 23 is inlaid therein; an outer frame assembly is also provided on the outside of the third frame 3, the fourth frame 4 and the fifth frame 5, and a heat insulation filler 19 is provided between the outer frame assemblies. The outer frame assembly is connected to the third frame 3 by a fixing component and a limiting component. The outer frame assembly is sealed and connected to the fifth frame 5 and the glass 23 by a third sealing element 10.

[0040] This composite passive window boasts excellent thermal insulation performance while ensuring the durability and stability of the window, meeting the requirements of passive windows. Furthermore, its simple overall structure makes it easy to assemble and use. This composite passive window achieves this by filling the outer frame assembly with thermal insulation material 19 to block heat transfer between the interior and exterior. The fifth frame 5, without being exposed, forms two insulation lines in the cross-section, thus improving the thermal insulation performance of the aluminum alloy window without altering the width of the spacer strip in the thermally broken aluminum alloy profile. This ensures the overall durability and stability of the window under the new structural system.

[0041] The second spacer 14 and the third spacer 15 can connect the first frame 1 and the third frame 3, and also form a space to accommodate the second thermal insulation filling cotton 18. Simultaneously, they serve as the mounting and fixing position for the second sealing element 9, forming a sealed and insulating structure with the first spacer 13. Similarly, the first spacer 13 and the fourth spacer 16, while connecting the second frame 2 and the fourth frame 4, can also form a space to accommodate the first thermal insulation filling cotton 17. The first thermal insulation filling cotton 17, the second sealing element 9, and the second thermal insulation filling cotton 18 can form a central thermal insulation structure. The flat structure above the fourth spacer 16 can also be used to install and support the glass 23.

[0042] Furthermore, the outer frame assembly includes a sixth frame 6 and a seventh frame 7 that are fastened together, and the space enclosed by the sixth frame 6 and the seventh frame 7 is filled with the heat insulation filler 19; the third sealing member 10 is provided at the upper fastening point of the sixth frame 6 and the seventh frame 7; the fixing component is provided on the side of the seventh frame 7 facing the third frame 3 and connected to the third frame; and the limiting component is provided above the third frame 3 and between the seventh frame 7.

[0043] The sixth frame 6 and the seventh frame 7 are connected by snap-fit ​​and filled with heat insulation material in the middle, which can effectively reduce the heat transferred between the indoor and outdoor areas through the frame. The fixing component is used to fix it to the third frame 3, so that the two frames are connected in a linear connection. The limiting component is used to further connect the seventh frame 7 and the third frame 3, so that the two are connected by a combination of point connection and linear connection, forming a more stable structure.

[0044] Furthermore, the third sealing member 10 includes an inner snap-fit ​​portion 1001, a hollow elastic sealing portion 1002 located on one side of the snap-fit ​​portion 1001, and a free elastic arm 1003 on the other side. The snap-fit ​​portion 1001 snaps onto the K-shaped snap-fit ​​wall 501 above the fifth frame 5, the hollow elastic sealing portion 1002 abuts against the outer side of the glass 23, and the free elastic arm 1003 forms a sealing structure between the fifth frame 5 and the outer frame assembly.

[0045] The third sealing element 10, with this structure, can connect the fifth frame 5, form a sealing structure at the connection between the sixth frame 6 and the seventh frame 7, and also form a sealing structure with the glass, while concealing the entire fifth frame 5 internally. The K-shaped snap-fit ​​wall 501 above the fifth frame 5 can effectively fix the third sealing element, providing a stable and reliable connection to the snap-fit ​​portion. The third sealing element 10 is a sealing strip structure.

[0046] Furthermore, the fixing component includes an I-shaped connector 21 and a self-tapping screw 22. The connector 21 is engaged in a reserved T-shaped groove on the side wall of the seventh frame 7 and its other end abuts against the outer wall of the third frame 3. The self-tapping screw 22 connects the connector 21 and the third frame 3. An L-shaped reserved protrusion 27 is also provided above the reserved T-shaped groove. A fifth sealing member 12 is also engaged between the reserved protrusion 27 and the outer wall of the third frame 3.

[0047] The connector 21 is designed to easily connect with the pre-reserved T-slot and is connected to the third frame 3 using the self-tapping screw 22 to form a fixed structure. The head of the self-tapping screw 22 is located inside the connector and is not exposed, so it does not affect the tight connection of adjacent frames. By setting the pre-reserved protrusion 27, the fifth sealing element 12 can be easily set at this connection gap to form a sealing structure at the joint.

[0048] Furthermore, the limiting component includes an inclined limiting card 20, one end of which is provided with a folded edge structure, which is connected to the limiting groove of the seventh frame 7, and the other end of which is provided with a snap-fit ​​structure, which is snapped and fixed in the snap-fit ​​groove above the third frame 3.

[0049] The limiting card 20, when inserted into the limiting grooves of the third frame 3 and the seventh frame 7, can increase the number of connection points between the third frame 3 and the seventh frame 7, making the overall structure more stable and ensuring the durability and stability of the entire window; multiple such limiting cards 20 can be set sequentially at intervals along the length direction, making connection and installation simple and convenient.

[0050] Furthermore, an extension arm is provided below the second frame 2, and a lateral reserved groove 26 is provided on the inner side of the extension arm. The first sealing member 8 is embedded in the reserved groove 26, and the free end of the first sealing member 8 abuts against the first frame 1.

[0051] Furthermore, the second spacer 14 and the third spacer 15 are arranged in parallel, and the inner sides of the second spacer 14 and the third spacer 15 are provided with corresponding baffle structures. The area between the baffle structures is filled with the second heat insulation filling cotton 18. The first spacer 13 and the fourth spacer 16 are arranged in parallel, and the first spacer 13 is arranged relative to the second spacer 14. The first spacer 13 is also provided with a baffle structure above it, and the space between it and the fourth spacer 16 is filled with the first heat insulation filling cotton 17.

[0052] The baffle structure can form a groove between the upper and lower spacers to accommodate the heat insulation filling cotton, ensuring that the heat insulation filling cotton is in the predetermined position for heat insulation and will not loosen or move.

[0053] Furthermore, multiple C-shaped grooves 25 are arranged side-by-side above the second spacer 14. These C-shaped grooves 25 are used to engage and connect the second seal 9. The second seal 9 covers the entire second spacer 14 and the seams on both sides connecting it to the first frame 1 and the third frame 3. The top of the second seal 9 abuts against the first spacer 13. The interior of the second seal 9 also has multiple cavities, and a unidirectional limiting structure can be formed at the connection between the second seal 9 and the first spacer 13.

[0054] The second sealing element 9 can be stably connected by multiple C-shaped grooves 25, forming a long sealing structure that can seal the joints on both sides of the spacer strip and form a spatial sealing structure with the first spacer strip above.

[0055] Furthermore, a glass pad is provided above the fourth spacer 16. The cross-sectional dimension of the glass pad is larger than that of the fourth spacer 16. The two sides of the glass pad press against the edges of the second frame 2 and the fifth frame 5, respectively, which can limit the fifth frame 5 and close the gap between the fourth frame 4, the second frame 2 and the fourth spacer 16. The glass 23 is provided above the glass pad. The glass 23 is multi-layer hollow tempered glass. Warm edge spacers 24 are provided between the glass 23. A fourth sealing member 11 is also snapped between the side wall of the glass 23 and the second frame 2.

[0056] Furthermore, a method for installing a composite passive window includes the following steps:

[0057] First, insert the second heat insulation filling cotton 18 into the baffle structure of the second spacer 14 and the third spacer 15, and then fasten the first frame 1 and the third frame 3 to the second spacer 14 and the third spacer 15 to establish a stable profile structure.

[0058] The second step is to connect the sixth frame 6 and the seventh frame 7 with snap fasteners to form an outer frame assembly with a cavity structure, and fill the sixth frame 6 and the seventh frame 7 with heat insulation filler 19. After filling, the seventh frame 7 is connected to the third frame 3 with connector 21 and self-tapping screw 22 to form a double-layer heat insulation frame.

[0059] The third step is to insert several limiting clips 20 between the third frame 3 and the seventh frame 7 and engage them to increase the number of connection points between the third frame 3 and the seventh frame 7, making the overall structure more stable and ensuring the durability and stability of the entire window.

[0060] Fourth step, insert the first heat insulation filling cotton 17 into the baffle structure of the first spacer 13, and then fasten the second frame 2 and the fourth frame 4 to the first spacer 13 and the fourth spacer 16.

[0062] The sixth step is to fasten the fifth frame 5 onto the fourth frame 4, and form a glass inlay groove between the fifth frame 5 and the second frame 2 and the fourth spacer 16. A glass pad is placed in the glass inlay groove and then the glass 23 is inlaid. The third sealing member 10 is then installed in the gap between the glass 23 and the fifth frame 5.

[0063] The seventh step involves embedding a second sealing element 9 above the second spacer 14 and embedding a first sealing element 8 below the second frame 2. The seventh frame 7, the third frame 3, and the first frame 1 are then connected to the fifth frame 5 and the second frame 2 to form a double-cavity sealing structure, which can effectively block the exchange of internal and external heat flow and achieve a passive heat insulation effect.

[0064] This installation method is simple to operate and requires few tools. The components are basically connected and fixed by snap-fit ​​and fastening. On the outside of the glass 23, the first insulation line is composed of the third sealing element 10, the fifth frame 5, the seventh frame 7, and the thermal insulation filler 19. In the middle of the cross-section, the second insulation line is composed of the warm edge spacer 24, the first spacer 13, the fourth spacer 16, the first thermal insulation filler 17, the second sealing element 9, the second spacer 14, the third spacer 15, and the second thermal insulation filler 18.
