Description

Technical Field

[0001] The present invention generally relates to the field of building structures, and particularly to a passive house with a sealed window frame. Background Art

[0002] A passive house refers to a building that uses a series of measures such as ultra-thick thermal insulation materials, an efficient door and window system, good airtightness design, and a thermally broken design. Without the need for active heating and cooling equipment, the building can maintain a comfortable indoor temperature and humidity environment only relying on its own heat gain (such as solar radiation, human body heat dissipation, equipment heat dissipation, etc.).

[0003] During the installation process of the window and the wall, it is necessary to consider the installation gap between the window frame and the inner wall of the wall to accommodate thermal expansion and contraction and tolerance adjustment. In the common installation process, it is necessary to fill the installation gap between the window frame and the wall with foaming materials to fill the installation gap between the window frame and the inner wall of the wall, so as to achieve a sealing effect. However, only by filling with foaming materials, under the action of external forces, the displacement of the window frame will cause gaps between the foaming materials, thus affecting the indoor thermal insulation effect.

[0004] Therefore, the inventor believes that the common fixed structure between the window frame and the wall cannot effectively fill the voids, thus affecting the indoor thermal insulation effect. Summary of the Invention

[0005] In view of the problems existing in the above-mentioned prior art, the present invention provides a passive house with a sealed window frame, including: A frame body, which is formed by connecting a plurality of side frames end to end; A side frame, on the side facing the wall, a support sealing structure is provided, and on the side facing the wall of the edge, a groove is opened along the length direction of the side frame; the support sealing structure includes: Support sealing strips, there are two of them, located on both sides of the groove, arranged along the length direction of the groove, and part of the structure is embedded inside the frame body; A main airbag, which is fixed to the bottom wall of the groove and arranged along the length direction of the groove; A one-way valve, fixed to one side of the side frame and communicating with the main airbag.

[0006] By having the above-mentioned technical features, the supporting sealing strip plays an auxiliary supporting role for the frame, and in the initial stage of fixing the frame, the wear between the inner wall of the wall and the main airbag is avoided. After the position of the frame is determined, the main airbag in the one-way valve can be filled with gas to expand the main airbag into the gap between the frame and the inner wall of the wall. Moreover, the structure of the main airbag itself can make up for the rough surface of the wall and will not cause new gaps. Even after the frame and the wall are rigidly connected, the vibration caused by external force can cause the main airbag to deform and make up for the gap, thereby ensuring the sealing effect between the frame and the wall.

[0007] In some embodiments, the supporting sealing strip is slidably connected to the frame toward the fixed wall. A bottom film is arranged between the two supporting sealing strips, and the edges on both sides of the bottom film are fixed to the ends of the supporting sealing strips. Therefore, during the inflation of the main airbag, it will abut against the bottom film and drive the bottom film to move toward the wall. The length of the bottom film is limited, which will also drive the supporting sealing strip to move toward the wall. Moreover, the bottom film avoids direct contact between the main airbag and the inner wall of the wall, so that the supporting sealing strip plays a protective role for the main airbag. Moreover, in some embodiments, as the gas inside the main airbag is filled, it expands to both sides and squeezes the side walls of the supporting sealing strips on both sides, thereby increasing the friction between the supporting sealing strip and the frame, so that the supporting sealing strip is fixed at the sliding extended position and protects both sides of the main airbag.

[0008] In some embodiments, it also includes: The auxiliary support strip is fixed to the side of the bottom film away from the main airbag and extends along the length direction of the main airbag. Therefore, 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 of the wall, the length of the bottom film is limited, which will drive the ends of the support sealing strips on both sides to bend elastically toward the auxiliary support strip. As the main airbag is filled with gas, the support sealing strips on both sides cover the main airbag more tightly, which not only fills the gap between the frame and the inner wall of the wall, but also greatly improves the protection of the main airbag, and is not easy to cause damage to the main airbag.

[0009] In some embodiments, a channel is provided on the bottom wall of the groove and is interconnected with the root of the supporting sealing strip. The passage is provided with an auxiliary airbag interconnected with the main airbag, and the auxiliary airbag is located in the root area of ​​the supporting sealing strip with a filling margin. Therefore, when the main airbag is inflated, part of the gas also fills the auxiliary airbag, thereby expanding in the root area of ​​the supporting sealing strip and applying force to the root of the supporting sealing strip, driving the supporting sealing strip to move toward the wall, thereby improving the sealing efficiency of the supporting sealing strip.

[0010] In some embodiments, the main airbag includes a rigid airbag wall that fits against the two side walls of the groove. Thus, when the main airbag is being filled with gas, the rigid airbag wall restricts the expansion of the gas in both lateral directions and drives the main airbag to displace preferentially towards the wall. Moreover, the rigid airbag wall also restricts the extrusion of the main airbag against the side wall of the support sealing strip, ensuring the stability of the displacement of the support sealing strip.

[0011] In some embodiments, the main airbag further includes: a flexible thick airbag wall connected to the side of the two rigid airbag walls facing the wall, and a flexible airbag wall connected to the rigid airbag wall facing the bottom of the groove. Thus, on the one hand, the flexible thick airbag wall restricts its own expansion, and on the other hand, it is not easily damaged after contact with the rough surface, improving the overall service life of the main airbag; while the flexible airbag wall at the root deforms preferentially with the filling of gas, accelerating the displacement and filling efficiency of the main airbag.

[0012] In some embodiments, the frame is provided with fixing bolts for fixing to the wall on the side of the support sealing strip facing away from the airbag. Thus, under the positioning and sealing limit of the main airbag, and then through the fixing of the fixing bolts, the mutual fixing between the frame and the inner wall of the wall is achieved first, ensuring the stability of the fixing of the frame.

[0013] In some embodiments, at least two support sealing structures are provided along the length direction of the groove. Thus, at the initial stage of fixing the frame, the staff can adjust the overall angle of the frame by adjusting the air pressure of different main airbags, and moreover, the stacking of redundant support structures is reduced, greatly improving the efficiency of alignment and fine adjustment.

[0014] In some embodiments, at least two channels are provided at intervals along the length direction of the groove, and auxiliary airbags are provided in each channel. Thus, the stability of the force on each area of the sealing support strip is ensured, and the displacement efficiency of the sealing support strip is ensured.

[0018] Next, the preferred embodiments (or implementation manners) of the present invention will be described in detail with reference to the accompanying drawings.

[0019] Next, refer to Figures 1-5 to describe a passive house with a sealed window frame of the present invention.

[0020] Figure 1 Shows a schematic diagram of the overall structure of a passive house with a sealed window frame according to an embodiment of the present invention. Refer to Figure 1 As shown, a window frame structure for a passive house provided in this embodiment includes a house body 9 and a frame body 1 installed in the lighting area of the house body 9. A window body 3 is slidably connected in the frame body 1. At least two window bodies 3 are provided to satisfy the occlusion of the space of the frame body 1. Among them, the frame body 1 is composed of a plurality of frames 2 connected end to end to form a rectangular structure.

[0021] Figure 2 Shows a partial view of the frame 2 in a passive house with a sealed window frame according to an embodiment of the present invention. Refer to 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 arranged along the length direction of the frame 2, and penetrates through both ends of the frame 2; a slide groove 22 is further provided on the bottom wall of the frame 2 where the groove 21 is opened. Two slide grooves 22 are provided and located on both sides of the groove 21, and are arranged along the length direction of the groove 21.

[0022] Figure 3 Shows a cross-sectional view of the internal structure of the frame 2 in a passive house with a sealed window frame according to an embodiment of the present invention. Refer to Figure 3As shown in the figure, a support and sealing structure is provided between the frame 2 and the inner wall of the wall. The support and sealing structure includes a support sealing strip 4 disposed inside each chute 22 along the length of the chute 22. The support sealing strip 4 can be a strip structure made of rubber material, located inside the chute 22 and slidably connected to the inner wall of the chute 22 in the direction towards the wall. In the initial state, a part of the support sealing strip 4 protrudes from the top of the chute 22. For the frame 2 at the bottom, its support sealing strip 4 will first come into contact with the inner wall of the wall and support the frame 1.

[0023] Since the support sealing strip 4 is made of a flexible material, in order to improve the sliding efficiency of the support sealing strip 4 inside the chute 22, a limiting support plate 41 is attached to each of the opposite sides of the support sealing strip 4, thereby increasing the overall support strength of the support sealing strip 4 and also increasing the smoothness on both sides of the support sealing strip 4, improving the sliding efficiency of the support sealing strip 4.

[0024] Figure 4 The figure shows a schematic structural view of the support sealing strip 4 in a passive house with a sealed window frame according to an embodiment of the present invention. Refer to Figure 4 As shown in the figure, in some embodiments, a plurality of limiting sliding strips 42 protrude from the side of the limiting support plate 41 facing away from the support sealing strip 4. A limiting chute 23 that cooperates with the limiting sliding strips 42 is also provided in the area of the inner wall of the chute 22 opposite to the position of the limiting sliding strips 42, thereby restricting the reciprocating sliding of the support sealing strip 4 along the direction towards the inner wall of the wall with the inner wall of the chute 22.

[0025] Looking back Figure 3 As shown in the figure, a main airbag 5 is disposed along the length direction inside the groove 21. The main airbag 5 is fixed to the bottom wall of the groove 21. During the inflation process of the main airbag 5, its two sides abut against the opposite inner walls of the groove 21, forming an inflated air chamber. Structurally, it includes a rigid bladder wall 51 that abuts against the inner wall of the groove 21, a flexible thick bladder wall 52 that is connected between the two rigid bladder walls 51 on the side facing the wall, and a flexible bladder wall 53 that is connected to the two rigid bladder walls 51 in the direction towards the bottom wall of the groove 21.

[0026] The rigid bladder wall 51, the flexible rigid bladder wall 51, and the flexible bladder wall 53 are all made of rubber material. However, a metal mesh structure is fixed inside the rigid bladder wall 51, making its deformation amount limited after inflation; while the flexible thick bladder wall 52 is located in the area in contact with the wall. Due to the thickness of its own material, it is beneficial for long-term wear with the wall and is not easily damaged by air leakage of the main airbag 5; and the flexible airbag is located inside the groove 21 and is the main deformation area of the main airbag 5. Therefore, when inflating the main airbag 5, the gas will first expand through the flexible airbag to drive the rigid bladder wall 51 and the flexible thick bladder wall 52 to displace towards the wall, so that the flexible thick bladder wall 52 abuts against the inner wall of the wall, realizing the filling of the gap.

[0027] In some embodiments, a bottom film 61 is further disposed between the two support sealing strips 4. The bottom film 61 is strip-shaped and arranged along the length direction of the groove 21, and the two side edges of the bottom film 61 are fixed to the protruding surfaces of the support sealing strips 4. When the frame 2 is placed in the wall window, the bottom film 61 first contacts the inner wall of the wall under the spreading of the support sealing strips 4. The bottom film 61 can be a polyurethane film, which has high strength and elasticity and excellent wear resistance; the bottom film 61 can also be a nylon film, which has high strength and toughness and good wear resistance. As the main airbag 5 is inflated, the flexible rigid bladder wall 51 first contacts the bottom film 61 and drives the bottom film 61 to displace towards the inner wall of the wall. Since the bottom film 61 is fixed to the support sealing strips 4 on both sides, the support sealing strips 4 are driven to slide along the inner wall of the chute 22 and displace as the main airbag 5 expands. The displaced support sealing strips 4 are located on both sides of the main airbag 5 and play a protective role for the main airbag 5.

[0028] In some embodiments, on the side of the bottom film 61 facing away from the main airbag 5, an auxiliary support strip 62 is provided. The auxiliary support strip 62 is fixed on the surface of the bottom film 61 along the length direction of the groove 21. The auxiliary support strip 62 is made of the same material as the support sealing strip 4, which is a strip plate made of rubber material. Figure 5 The cross-sectional view in the fixed state of a passive house using a sealed window frame according to an embodiment of the present invention is shown. Refer to Figure 5 As shown, with the filling of the gas inside the main airbag 5, the auxiliary support strip 62 is driven to first abut against the inner wall of the wall. As the gas continues to be supplied, the bottom film 61 covers both sides of the auxiliary support strip 62 and plays a pulling role on the ends of the support sealing strips 4 on both sides, improving the acting force of the ends of the support sealing strips 4 on the inner wall of the wall and further achieving a sealing effect between the inner wall of the wall and the side of the frame 2.

[0029] As Figure 3 and Figure 5 As shown, a channel 24 communicating with the bottom walls of the two side chutes 22 is opened at the bottom of the groove 21. An auxiliary airbag 7 is arranged in the channel 24. One end of the auxiliary airbag 7 is communicated with the inside of the main airbag 5, and the other end extends to the root of the chute 22. As the gas is supplied into the main airbag 5, part of the gas will enter the auxiliary airbag 7. There is a filling margin at the end of the auxiliary airbag 7, so that the auxiliary airbag 7 squeezes the root of the support sealing strip 4 and drives the support sealing strip 4 to slide towards the wall, thus greatly improving the sliding efficiency of the support sealing strip 4 along the inner wall of the chute 22 and also improving the squeezing acting force of the end of the support 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.

[0030] In some embodiments, at least two channels 24 are provided along the length direction of the groove 21, and a spacing is left between adjacent grooves 21, and the auxiliary airbags 7 are provided in plurality and are located in each channel 24. On the one hand, the addition of a plurality of auxiliary airbags 7 increases the support area with the support sealing strip 4, ensures the stability of the force of the support sealing strip 4, and further ensures the stable sliding of the support sealing strip 4 and the inner wall of the slide groove 22.

[0031] In some embodiments, at least two supporting sealing structures are provided on the frame 2 along the length direction of the groove 21, and adjacent supporting sealing structures abut against each other, so that after the frame 1 is placed in the installation area, the fixed level of the frame 1 can be fine-tuned by regulating the air pressure of different main airbags 5. Figure 1 At least one inflation port is provided on one side of each frame 2, and a one-way valve 8 interconnected with the main airbag 5 is provided in each inflation port. During the inflation process, no auxiliary support structure is required, and the initial fixation of the frame 1 is achieved only by the friction between the main airbag 5 and the inner wall of the wall. Finally, a plurality of fixing bolts can be provided at intervals on the side of the frame 2 that supports the sealing strip 4 away from the airbag. The fixing bolts and the wall are mutually fixed to achieve a rigid connection between the frame 1 and the wall, thereby 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 the impact of external force, the main airbag 5 can be connected to the wall flexibly to fill the gap between the wall and the frame 1, thereby ensuring the sealing between the frame 1 and the wall.

[0032] Furthermore, the gap between the frame 1 and the wall can be filled with foam glue in a conventional manner, and the sealing glue on the side can be applied to further improve the sealing between the frame 1 and the wall.
