Description

Technical Field

[0001] This invention generally relates to the field of building construction, and more specifically to a passive house employing a sealed window frame. Background Technology

[0002] Passive houses refer to buildings that employ a series of measures, such as ultra-thick thermal insulation materials, efficient door and window systems, good airtight design, and thermal bridge-free design, so that the building can maintain a comfortable indoor temperature and humidity environment by relying solely on the heat gained by the building itself (such as solar radiation, human body heat dissipation, equipment heat dissipation, etc.) without the need for active heating and cooling equipment.

[0003] During window installation, the installation gap between the window frame and the inner wall needs to be considered to accommodate thermal expansion and contraction and adjustments to tolerances. Common installation methods involve filling this gap with expanding foam to achieve a seal. However, simply filling with foam can lead to gaps between the foam layers due to frame displacement under external forces, thus affecting the room's insulation performance.

[0004] Therefore, the inventor believes that the common fixed structure between window frames and walls cannot effectively fill the gaps, thus affecting the indoor insulation effect. Summary of the Invention

[0005] In view of the problems existing in the prior art described above, the present invention provides a passive house employing a sealed window frame, comprising:

[0006] The frame is composed of multiple borders connected end to end;

[0007] A frame, having a supporting and sealing structure on the side facing the wall, wherein a groove is formed along the length of the frame on the side facing the wall; the supporting and sealing structure includes:

[0008] Two supporting sealing strips are provided and located on both sides of the groove, arranged along the length of the groove, with part of their structure embedded inside the frame.

[0009] The main airbag is fixed to the bottom wall of the groove and is arranged along the length of the groove;

[0010] A one-way valve is fixed to one side of the frame and is in communication with the main airbag.

[0011] With the aforementioned technical features, the supporting sealing strip plays an auxiliary supporting role for the frame. In the initial stage of frame fixing, it avoids wear between the inner wall of the wall and the main airbag. After the frame position is determined, gas can be filled into the main airbag through the one-way valve, and the main airbag expands into the gap between the frame and the inner wall of the wall. Moreover, the structure of the main airbag itself can compensate for the rough surface of the wall and will not create new gaps. Even after the frame and the wall are rigidly connected, the main airbag can deform to compensate for the gaps caused by external forces, ensuring the sealing effect between the frame and the wall.

[0012] In some embodiments, the supporting sealing strip is slidably connected to the frame in the direction of the fixed wall.

[0013] A bottom membrane is disposed between the two supporting sealing strips, and the two side edges of the bottom membrane are fixed to the ends of the supporting sealing strips. Thus, during the inflation of the main airbag, it abuts against the bottom membrane and causes the bottom membrane to shift towards the wall. The limited length of the bottom membrane also causes the supporting sealing strips to shift towards the wall. Furthermore, the bottom membrane prevents direct contact between the main airbag and the inner wall, thus protecting the main airbag. In some embodiments, as the main airbag is filled with gas, it expands to both sides and presses against the side walls of the supporting sealing strips, increasing the friction between the supporting sealing strips and the frame. This fixes the supporting sealing strips in their extended, sliding position, protecting both sides of the main airbag.

[0014] In some embodiments, it also includes:

[0015] The auxiliary support strip is fixed to the side of the bottom membrane opposite to the main airbag and extends along the length of the main airbag. Thus, the auxiliary support strip replaces the direct contact between the main airbag and the inner wall of the wall. When the auxiliary support strip abuts against the inner wall, the limited length of the bottom membrane causes the ends of the support sealing strips on both sides to elastically bend towards the auxiliary support strip. As the main airbag is filled with gas, the support sealing strips on both sides provide a tighter enclosure of the main airbag, not only filling the gap between the frame and the inner wall of the wall but also greatly improving the protection of the main airbag and reducing the risk of damage.

[0016] In some embodiments, the bottom wall of the groove is provided with a channel communicating with the root of the supporting sealing strip.

[0017] An auxiliary airbag, interconnected with the main airbag, is installed within the channel. The auxiliary airbag is located at the root of the supporting sealing strip, with sufficient filling allowance. Thus, while the main airbag is inflated, some gas also fills the auxiliary airbag, expanding the area at the root of the supporting sealing strip and applying force to it, causing the supporting sealing strip to shift towards the wall, thereby improving its sealing efficiency.

[0018] In some embodiments, the main airbag includes a rigid airbag wall that fits against the side walls of the groove. Thus, during the gas filling process, the rigid airbag wall restricts the gas expansion in both directions and causes the main airbag to preferentially displace towards the wall. Furthermore, the rigid airbag wall also restricts the compression of the main airbag against the side walls of the supporting sealing strip, ensuring the stability of the supporting sealing strip's displacement.

[0019] In some embodiments, the main airbag further includes:

[0020] A flexible, thick capsule wall connecting the two rigid capsule walls on the side facing the wall.

[0021] And a flexible airbag wall connected to the rigid airbag wall facing the bottom of the groove. Thus, the flexible thick airbag wall restricts its own expansion on the one hand, and is not easily damaged after contact with the rough surface, thereby improving the overall service life of the main airbag; while the flexible airbag wall at the root deforms preferentially as the gas is filled, accelerating the displacement and filling efficiency of the main airbag.

[0022] In some embodiments, the frame is provided with fixing bolts on the side of the supporting sealing strip opposite to the airbag, which are fixed to the wall. Thus, by positioning and sealing the main airbag, and then fixing it with the fixing bolts, the mutual fixation between the frame and the inner wall of the wall is first achieved, ensuring the stability of the frame fixation.

[0023] In some embodiments, at least two supporting sealing structures are provided along the length of the groove. Therefore, during the initial fixing of the frame, workers can fine-tune the overall angle of the frame by adjusting the air pressure of different main airbags, thus reducing the need for redundant supporting structures and greatly improving the efficiency of alignment adjustments.

[0024] In some embodiments, at least two channels are spaced apart along the length of the groove, and each channel contains an auxiliary airbag. This ensures the stability of the force on each area of ​​the sealing support strip and guarantees the displacement efficiency of the sealing support strip.

[0025] It should be understood that the description in the Summary of the Invention is not intended to limit the key or essential features of the embodiments of this disclosure, nor is it intended to restrict the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

Detailed Implementation

[0033] The preferred embodiments (or implementation methods) of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] The following is for reference. Figures 1-5 This invention describes a passive house employing a sealed window frame.

[0035] Figure 1 A schematic diagram of the overall structure of a passive house employing a sealed window frame, according to an embodiment of the present invention, is shown. (Reference) Figure 1 As shown, the window frame structure for a passive house provided in this embodiment includes a roof 9 and a frame 1 installed in the lighting area of ​​the roof 9. A window 3 is slidably connected inside the frame 1. At least two windows 3 are provided to meet the shading requirements of the space in the frame 1. The frame 1 is a rectangular structure composed of multiple side frames 2 connected end to end.

[0036] Figure 2 A partial schematic diagram of the frame 2 in a passive house employing a sealed window frame, according to an embodiment of the present invention, is shown. (See reference) Figure 2 As shown, a groove 21 is provided on the side of the frame 2 facing the inner wall of the wall. The groove 21 is strip-shaped and is set along the length of the frame 2, penetrating both ends of the frame 2. A sliding groove 22 is also provided on the bottom wall of the frame 2 with the groove 21. There are two sliding grooves 22 located on both sides of the groove 21 and arranged along the length of the groove 21.

[0037] Figure 3A cross-sectional view of the internal structure of the frame 2 in a passive house employing a sealed window frame, according to an embodiment of the present invention, is shown. (See reference) Figure 3 As shown, a support and sealing structure is provided between the frame 2 and the inner wall of the wall. This support and sealing structure includes a support sealing strip 4, which is disposed along the length of each groove 22 inside the groove 22. The support sealing strip 4 can be a strip-shaped structure made of rubber, located within the groove 22 and slidingly connected to the inner wall of the groove 22 towards the wall. In the initial state, the support sealing strip 4 protrudes from the top of the groove 22 and is located at the bottom of the frame 2. The support sealing strip 4 preferentially contacts the inner wall of the wall and supports the frame 1.

[0038] Since the supporting sealing strip 4 is made of flexible material, in order to improve the sliding efficiency of the supporting sealing strip 4 in the groove 22, a limiting support plate 41 is attached to each of its opposite sides, thereby increasing the overall supporting strength of the supporting sealing strip 4, and also increasing the smoothness of both sides of the supporting sealing strip 4, thus improving the sliding efficiency of the supporting sealing strip 4.

[0039] Figure 4 This diagram illustrates a structural schematic of a support sealing strip 4 in a passive house employing a sealed window frame, according to an embodiment of the present invention. (Refer to...) Figure 4 As shown, in some embodiments, the limiting support plate 41 is provided with a plurality of limiting slide strips 42 on the side opposite to the supporting sealing strip 4, and the inner wall of the slide groove 22 is provided with a limiting slide groove 23 that cooperates with the limiting slide strip 42 in the area opposite to the position of the limiting slide strip 42, thereby restricting the supporting sealing strip 4 from sliding back and forth against the inner wall of the slide groove 22.

[0040] Looking back Figure 3 As shown, a main airbag 5 is arranged along the length of the groove 21 and is fixed to the bottom wall of the groove 21. During the inflation process, the main airbag 5 abuts against the opposite inner walls of the groove 21 on both sides, forming an inflated air chamber. Structurally, it includes a rigid airbag wall 51 that abuts against the inner wall of the groove 21, a flexible thick airbag wall 52 that connects the two rigid airbag walls 51 to the wall side, and a flexible airbag wall 53 that connects the two rigid airbag walls 51 towards the bottom wall of the groove 21.

[0041] The rigid airbag wall 51, the flexible rigid airbag wall 51, and the flexible airbag wall 53 are all made of rubber. However, the rigid airbag wall 51 has a fixed metal mesh structure inside, which limits its deformation after inflation. The flexible thick airbag wall 52 is located in the area that is in contact with the wall. Its own material thickness is conducive to long-term wear and tear with the wall and is not likely to cause leakage damage to the main airbag 5. The flexible airbag is located inside the groove 21 and is the main deformation area of ​​the main airbag 5. Therefore, when the main airbag 5 is inflated, the gas will preferentially expand through the flexible airbag, causing the rigid airbag wall 51 and the flexible thick airbag wall 52 to move towards the wall. This allows the flexible thick airbag wall 52 to abut against the inner wall of the wall, thus filling the gap.

[0042] In some embodiments, a bottom membrane 61 is also provided between the two supporting sealing strips 4. The bottom membrane 61 is strip-shaped and arranged along the length direction of the groove 21. The two side edges of the bottom membrane 61 are fixed to the protruding surfaces of the supporting sealing strips 4, so that when the frame 2 is placed inside the wall window, the bottom membrane 61, under the spread of the supporting sealing strips 4, preferentially contacts the inner wall of the wall. The bottom membrane 61 can be a polyurethane membrane, which has high strength and elasticity and excellent wear resistance; the bottom membrane 61 can also be a nylon membrane, which has high strength and toughness and good wear resistance. As the main airbag 5 is inflated, the flexible rigid airbag wall 51 first contacts the bottom membrane 61 and drives the bottom membrane 61 to move towards the inner wall of the wall. Since the bottom membrane 61 is fixed to the supporting sealing strips 4 on both sides, it drives the supporting sealing strips 4 to slide against the inner wall of the groove 22 and move with the expansion of the main airbag 5. The displaced supporting sealing strips 4 are located on both sides of the main airbag 5, which plays a protective role for the main airbag 5.

[0043] In some embodiments, an auxiliary support strip 62 is provided on the side of the bottom membrane 61 opposite to the main airbag 5. The auxiliary support strip 62 is fixed to the surface of the bottom membrane 61 along the length direction of the groove 21. The auxiliary support strip 62 and the support sealing strip 4 are made of the same material, namely rubber strips. Figure 5 A sectional view of a passive house in a fixed state using a sealed window frame, according to an embodiment of the present invention, is shown. (Refer to...) Figure 5 As shown, as the main airbag 5 is filled with gas, the auxiliary support strip 62 first comes into contact with the inner wall of the wall. As the gas is continuously supplied, the bottom membrane 61 covers both sides of the auxiliary support strip 62 and pulls on the ends of the support sealing strip 4 on both sides, increasing the force of the ends of the support sealing strip 4 on the inner wall of the wall, and further achieving the sealing effect between the support sealing strip 4 and the inner wall of the wall.

[0044] like Figure 3 and Figure 5As shown, a channel 24 is opened at the bottom of the groove 21, which communicates with the bottom walls of the two side slides 22. An auxiliary airbag 7 is installed in the channel 24. One end of the auxiliary airbag 7 is connected to the inside of the main airbag 5, and the other end extends to the root of the slide 22. As gas is supplied to the main airbag 5, some gas will enter the auxiliary airbag 7. The end of the auxiliary airbag 7 has a filling margin, which allows the auxiliary airbag 7 to squeeze the root of the supporting sealing strip 4 and drive the supporting sealing strip 4 to slide towards the wall. This greatly improves the sliding efficiency of the supporting sealing strip 4 and the inner wall of the slide 22, and also increases the squeezing force of the end of the supporting sealing strip 4 on the inner wall of the wall, ensuring the sealing of the gap between the inner wall of the wall and the side of the frame 2.

[0045] In some embodiments, at least two channels 24 are provided along the length of the groove 21, and a gap is left between adjacent grooves 21. Multiple auxiliary airbags 7 are provided and located in each channel 24. On the one hand, the addition of multiple auxiliary airbags 7 improves the support area of ​​the supporting sealing strip 4, ensuring the stability of the supporting sealing strip 4 under force. Furthermore, it also ensures the stable sliding of the supporting sealing strip 4 against the inner wall of the groove 22.

[0046] In some embodiments, at least two support sealing structures are provided on the frame 2 along the length of the groove 21, and adjacent support sealing structures abut against each other, so that after the frame 1 is placed in the installation area, the frame 1 can be finely adjusted to be fixedly horizontal by adjusting the air pressure of different main airbags 5. (See previous text) Figure 1 Each frame 2 has at least one inflation port on one side, and each inflation port contains a one-way valve 8 that communicates with the main airbag 5. During inflation, no auxiliary support structure is needed; the frame 1 is initially secured solely by the friction between the main airbag 5 and the inner wall of the wall. Finally, multiple fixing bolts can be spaced at intervals on the side of the frame 2 opposite to the airbag, which is supported by the sealing strip 4. By fixing the frame 1 to the wall with these bolts, a rigid connection between the frame 1 and the wall is achieved, improving the support strength of the frame 1 and the wall. Moreover, even if a slight displacement occurs between the frame and the wall due to an external impact, the main airbag 5 can fill the gap between the wall and the frame 1 through a flexible connection with the wall, thus ensuring the airtightness between the frame 1 and the wall.

[0047] Furthermore, conventional methods can be used to fill the gap between the frame 1 and the wall with expanding foam and apply sealant to the sides, which further improves the sealing performance between the frame 1 and the wall.
