Description

Technical Field

[0001] This invention relates to a method for installing doors and windows, and more particularly to a method for installing passive windows in zero-carbon buildings that are stable, easy to replace. Background Technology

[0002] The present invention patent, document number CN110965897B, entitled "Stable and Easily Replaceable Passive Window Installation Method for Zero-Carbon Buildings," describes a method where a concrete wall 2 with an external insulation layer 1 has a window (or doorway). During installation, the external insulation layer 1 extends towards the wall's doorway / window, forming an opening smaller than the opening. A high-density graphite polystyrene board frame 3 is bonded to the middle and outer sides of the wall's doorway / window end face, while a low-density graphite polystyrene board frame 31 with a thickness greater than the high-density graphite polystyrene board frame 3 is bonded to the inner side of the wall's doorway / window end face. A waterproof and breathable membrane 10 is first installed on the opening end face and the exterior facade of the high-density graphite polystyrene board frame, and then expansion bolts are installed on the inner side of its opening end face and tightened through the facade. The door and window mounting base frame 4 is fixed to the wall and the door and window frame 5. A waterproof and vapor barrier membrane 30 is set between the outdoor side facade of the low-density graphite polystyrene board frame 31 and the high-density graphite polystyrene board frame 3 and the door and window mounting base frame 4. The door and window mounting base frame 4 and the door and window frame 5 are embedded with a door and window mounting wood cap frame 40. The outdoor side facade of the door and window mounting base frame 4 is fixed with a high-density graphite polystyrene support frame 6. The door and window outer protective frame 50 is fastened to the door and window frame 5 and the high-density graphite polystyrene support frame 6, and the door and window mounting base frame 4 and the door and window mounting wood cap frame 40 are fixed to the outdoor side facade. The door and window connecting strip 7 is fixed to the outer facade of the wall and the door and window frame 50. It extends along the outer insulation layer 1 and is fixed to the top and both sides of the door and window outer protective frame 50. The surface of the low-density graphite polystyrene board frame 31 is first coated with a layer of crack-resistant mortar, then alkali-resistant fiber mesh is pressed into the crack-resistant mortar layer, and then covered with another layer of crack-resistant mortar, smoothed and polished.

[0003] However, the latest developments in zero-carbon building walls utilize a fully insulated wall structure, replacing concrete walls with graphite polystyrene insulation boards. When passive windows are added, the problem becomes apparent: the windows are not easily stabilized, and even after reinforcement, they are difficult to replace. Therefore, balancing window stability with ease of replacement is a common and often unattainable dilemma. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned deficiencies of the prior art and provide a stable and easily replaceable passive window installation method for zero-carbon buildings. In other words, passive windows installed according to the method of this invention are not only stable and easy to replace, but also remain stable after replacement.

[0005] To achieve the above objectives, the present invention provides a stable and easily replaceable passive window installation method for zero-carbon buildings. The method involves installing a window in the core of a graphite polystyrene insulation board wall. The window end face of the graphite polystyrene insulation board is adhered to the outer periphery of a convex-shaped high-density graphite polystyrene insulation board extending into the wall core, forming a centrally convex annular window within the wall core. Perlite insulation boards are installed on the inner and outer surfaces of the wall core using a steel wire mesh and V-shaped oblique metal wires. The window end faces of the high-density graphite polystyrene insulation boards on both sides of the centrally convex ring are first reinforced with inserted and connected U-shaped steel bars. Then, a cement mortar leveling layer is added to the inner and outer surfaces of the wall core, forming a window with… The wall features a centrally convex ring-shaped window with inner and outer recesses. The high-density graphite polystyrene insulation board window ends on the upper and lower concave sides, and the high-density graphite polystyrene insulation board window ends on the left and right concave sides, are first connected to the inner and outer connecting parts extending towards the window using expansion bolts. Cement mortar leveling areas are then provided on both sides of the centrally convex ring to stabilize the exposed parts of the expansion bolts and the bases of the connecting parts. The resulting passive window mounting base is fitted into the central ring between the inner and outer connecting parts via a base nail frame and inner and outer protective frames and sealing strips. The arms of the inner and outer connecting parts are respectively fixed to the inner and outer protective frames. This installation method results in a highly stable wall and passive window mounting base. The passive window installation base is fitted into the window frame via a base nail frame and inner and outer protective frames and sealing strips nailed thereto. The inner and outer connecting arms are then fixed to the inner and outer protective frames respectively. This not only ensures the stability of the passive window installation, but also allows for easy removal by simply disconnecting the protective frame and connecting arms on the inner or outer side and removing that side's protective frame and sealing strip. When replacing with a new passive window, it is also easy to simply press the new passive window in, reinstall the sealing strip and protective frame on that side, and fix the connecting arms. The replacement window remains stable. Therefore, passive windows offer the advantages of stable installation, easy replacement, and continued stability after replacement.

[0006] Preferred method: After reinforcing the inner and outer facades of the wall core with perlite insulation boards and U-shaped steel bars using wire mesh and V-shaped diagonally inserted metal wires, a water glass slurry layer is first applied to the surface of the perlite insulation board, followed by a cement mortar leveling layer. The water glass slurry layer is a sparse, sprayed layer. Ideally, after spraying the water glass slurry, the surface of the perlite insulation board should form an intermittently distributed layer of water glass slurry droplets. This promotes rapid and stable bonding between the perlite insulation board surface and the cement mortar leveling layer. The cement mortar leveling layer not only stabilizes quickly and does not affect its performance, but is also more stable and durable.

[0007] As an optimization, the connectors are angle steel connectors, which are easy to connect and have good stability; the fixing is either adhesive or screw-on, with adhesive being easier to install than screw-on and screw-on being easier to replace than adhesive; the base nail frame is a PU base nail frame, which is more conducive to heat insulation. The addition involves reinforcing with a steel wire mesh cover and V-shaped oblique metal wires, as well as adhesiveting adjacent perlite insulation boards and adhesiveting between perlite insulation boards and graphite polystyrene insulation boards. The fixing is preferably a combination of adhesive and screw-on.

[0008] As an optimization, an inner waterproof and vapor barrier membrane is provided on the outer periphery of the inner connector arm and the adjacent inner cement mortar leveling area window end face and the adjacent part of the inner protective frame. An outer waterproof and vapor-permeable membrane is provided between the inner section of the outer cement mortar leveling area opposite to the inner cement mortar leveling area, the outer side of the central convex ring, the adjacent high-density graphite polystyrene insulation board window end face, the base nail frame, and the adjacent part of the outer protective frame.

[0009] An external waterproof and breathable membrane is installed around the outer perimeter of the outer connector arm, the window end face of the adjacent outer cement mortar leveling area, and the adjacent part of the outer protective frame. Corner strips covering the external waterproof and breathable membrane and the adjacent part of the outer cement mortar leveling area are installed at the corners of the outer cement mortar leveling area. An internal waterproof and vapor-proof membrane is installed between the inner section of the inner cement mortar leveling area opposite to the outer cement mortar leveling area, the inner side of the central convex ring, the adjacent high-density graphite polystyrene insulation board window end face, and the adjacent parts of the base nail frame and inner protective frame. This arrangement of the internal and external waterproof and breathable membranes and corner strips ensures the window's internal waterproof and vapor-proof performance, external waterproof and breathable performance, and corner protection without affecting the stability and ease of replacement of the passive window.

[0010] As an optimization, the passive window installation base is further configured as follows: A corner guard is first installed at the corner of the outer cement mortar leveling area along the upper edge of the base. Then, as needed, an extended outer frame is installed to cover the exposed part of the outer cement mortar leveling area and its adjacent outdoor cement mortar leveling layer as a drip edge. The addition of drip edges is optional, depending on the different microclimates of low and high rainfall regions. Installing the corner guard first, followed by the drip edge, not only enhances the durability of the corner but also allows for easy replacement of the drip edge should the corner guard fail in the future.

[0011] As an optimization, the passive window installation base is also designed as follows: the outer end face of the cement mortar leveling area at the lower edge of the base is sloped from the bottom of the outer frame to the outside, which is very conducive to the rapid drainage of rainwater on the windowsill and effectively prevents rainwater from eroding the passive window; the sloped outer end face is fitted with an expansion sealing strip to set a metal windowsill plate extending out of the wall, which further prevents rainwater from penetrating and eroding the passive window and the exterior wall; the base of the metal windowsill plate is pressed under the outer frame, which significantly improves the pressure bearing and impact resistance of the metal windowsill plate.

[0012] As an optimization, the passive window frame is embedded in the base frame and the inner and outer protective frames and sealing strips connected to it. The inner and outer base plates of the PU rectangular base frame are respectively screwed to the inner and outer protective frames. The PU rectangular base frame is beneficial for heat insulation. By screwing the inner and outer protective frames to the inner and outer base plates respectively, the weakness of the PU rectangular base frame in terms of sturdiness can be overcome. The window end face of the rectangular base frame and the inner side of the window section of the inner and outer protective frames are respectively embedded in the end face sealing strips and the inner and outer side sealing strips to the outer peripheral end face and inner and outer side of the passive window frame. The sealing strips embedded in the passive window frame can achieve sealing through separate stress, resulting in good deformation resistance, sealing and durability.

[0013] As an optimization, the inner and outer substrates of the U-shaped cross section respectively wrap around the inner and outer ends of the rectangular base nail frame, resulting in high overall strength and greater stability; the outer peripheral end face of the passive window frame is interlocked with the PU material rectangular base nail frame and the substrate on either side of it to form a sealing tooth, providing good stable support performance.

[0014] As an optimization, the window ends of the inner and outer protective frames are respectively secured to the passive window frame by inner and outer sealing strips, and the window ends of the inner and outer protective frames are secured to the inner and outer sealing strips by grooves; the window ends of the inner and outer protective frames are secured to the inner and outer sealing strips by grooves and then the window frame is secured, which results in better sealing, pressure resistance, and stronger stability.

[0015] Alternatively, the window ends of the inner and outer protective frames can be reinforced with inner and outer sealing strips to secure the passive window frame. The window ends of the inner and outer protective frames are reinforced with inner and outer sealing strips through grooves. The thickness of the window ends of the inner and outer protective frames on the inner and outer connecting parts side is less than the thickness of the window ends of the corresponding inner and outer protective frames. This can significantly increase the support strength of the inner and outer protective frames on the inner and outer connecting parts side to the passive window frame, and significantly improve stability. Since the inner and outer protective frames on the opposite sides of the inner and outer connecting parts side are laterally inserted to compress the passive window frame, it is also beneficial to improve the stability strength of the passive window on the opposite side.

[0016] As an optimization, after the passive window frame is installed, the outer peripheral end face of the rectangular base nail frame is pressed and bonded to the inner peripheral end face of the convex ring and the adjacent window end faces of the inner and outer cement mortar leveling areas on both sides. This ensures both stability and thermal insulation performance. The pressing and bonding process involves simultaneously pressing and bonding the surfaces with an adhesive.

[0017] As an optimization, the steps for installing the passive window frame are as follows: 1) Screw the protective frame on either the indoor or outdoor side to the base nail frame, and install it into the mounting base, fixing the protective frame to the connector on that side; 2) Set end face sealing strips and side sealing strips on the window end face of the base nail frame 7 and the window end of the protective frame on that side, respectively, and then press them into the passive window frame; 3) Screw the protective frame on the opposite side with the opposite side sealing strip to the base nail frame, laterally embed and press the passive window frame, and fix the protective frame on that side to the connector. Removal is also straightforward; simply disassemble in reverse order. This not only ensures the stability and durability after installation but also makes disassembly and assembly very convenient. It can be easily installed and removed both indoors and outdoors, making it more suitable for indoor installation and replacement in high-rise buildings. Furthermore, due to the direct connection and limiting effect of the inner and outer connectors on the passive window, it will not fall in the event of a fire, and there is no thermal bridge after installation.

[0018] High-density graphite polystyrene insulation board has a density of 80 kg / m³. 3 High-density graphite polystyrene board with a thermal conductivity of 0.032 W / (mK) and a compressive strength of 650 kPa. Graphite polystyrene insulation board has a density of 18 kg / m³. 3 Low-density graphite polystyrene board with a thermal conductivity of 0.032 W / (mk).

[0019] After adopting the above technical solution, the present invention provides a stable and easily replaceable zero-carbon building passive window installation method with the advantages of stable and easy-to-replace passive windows, and the windows remain stable after replacement, will not fall in case of fire, and have no thermal bridges after installation.

Figure 2 and 3 They are Figure 1 A magnified view of the upper and lower parts of the window.

Figure 5 and 6 They are Figure 1 A magnified view of the middle left and right windows. Detailed Implementation

[0021] As shown in the figure, the installation method of the stable and easily replaceable zero-carbon building passive window of the present invention involves setting a window in the core of a graphite polystyrene insulation board 1. The window end face of the graphite polystyrene insulation board 1 is attached to the inner core of the wall by a convex high-density graphite polystyrene insulation board 2, forming a central convex ring-shaped window in the wall core. The inner and outer facades of the wall core are covered with perlite insulation board 4 by a steel wire mesh 3 and V-shaped oblique metal wires 31. The window end face of the high-density graphite polystyrene insulation board 2 on both sides of the central convex ring is first reinforced with U-shaped steel bars 23 inserted and connected. Then, a cement mortar leveling layer 5 is added to the inner and outer facades of the wall core to form a recessed platform. The window is a centrally convex ring-shaped wall. The high-density graphite polystyrene insulation board 2 window end face and the high-density graphite polystyrene insulation board 2 window end face of the left and right sides are first connected to the inner and outer connecting parts 52 extending towards the window by expansion bolts 51. Cement mortar leveling areas 6 are set on the inner and outer sides of the exposed part of the expansion bolts 51 and the base of the connecting parts 52 on both sides of the centrally convex ring. The passive window installation base is formed in the central ring between the above-mentioned inner and outer connecting parts 52. The passive window frame 9 is embedded in the base nail frame 7 and the inner and outer protective frames 8 and sealing strips that are screwed to it. The arms of the inner and outer connecting parts 52 are respectively fixed to the inner and outer protective frames 8. The passive window installation base is fitted into the window frame via a base nail frame and inner and outer protective frames and sealing strips nailed thereto. The inner and outer connecting arms are then fixed to the inner and outer protective frames respectively. This not only ensures the stability of the passive window installation, but also allows for easy removal by simply disconnecting the protective frame and connecting arms on the inner or outer side and removing that side's protective frame and sealing strip. When replacing with a new passive window, it is also easy to simply press the new passive window in, reinstall the sealing strip and protective frame on that side, and fix the connecting arms. The replacement window remains stable. Therefore, passive windows offer the advantages of stable installation, easy replacement, and continued stability after replacement.

[0022] Specifically, the connector 52 is an angle steel connector, and the fixing is either adhesive or screwed. The base nail frame 7 is a PU base nail frame. The installation involves reinforcing with a surface steel wire mesh and V-shaped oblique metal wires, while also bonding adjacent perlite insulation boards and bonding perlite insulation boards to graphite polystyrene insulation boards. The fixing is more preferably achieved through a combination of adhesive and screwing. Preferably, after reinforcing the inner and outer facades of the wall core with perlite insulation boards and U-shaped steel bars using a surface steel wire mesh and V-shaped oblique metal wires, a water glass slurry drip layer is first applied to the surface of the perlite insulation board, followed by a cement mortar leveling layer. The water glass slurry drip layer is a sprayed, sparse water glass slurry drip layer. After spraying the water glass slurry, the surface of the perlite insulation board is formed with a layer of water glass slurry droplets that are spaced apart. This promotes the rapid and stable bonding between the surface of the perlite insulation board and the cement mortar leveling layer. The cement mortar leveling layer is not only fast and stable and does not affect the normal performance of the cement mortar leveling layer, but is also more stable and durable.

[0023] Specifically, an inner waterproof and vapor barrier membrane 61 is provided on the outer periphery of the inner connector 52 arm and the adjacent inner cement mortar leveling area 6 window end face and the adjacent part of the inner protective frame 8. An outer waterproof and vapor-permeable membrane 62 is provided between the inner section of the outer cement mortar leveling area 6 opposite to the inner cement mortar leveling area 6, the outer side of the central convex ring, the adjacent high-density graphite polystyrene insulation board 2 window end face, the base nail frame 7 and the adjacent part of the outer protective frame 8.

[0024] An external waterproof and breathable membrane 62 is provided on the outer periphery of the arm of the outer connector 52 and the adjacent window end face and the adjacent part of the outer cement mortar leveling area 6 and the outer protective frame 8. A corner strip 71 covering the outer waterproof and breathable membrane 62 and the adjacent part of the outer cement mortar leveling area 6 is provided at the corner area of ​​the outer cement mortar leveling area 6. An internal waterproof and breathable membrane 61 is provided between the inner section of the inner cement mortar leveling area 6 opposite to the outer cement mortar leveling area 6, the inner side of the central convex ring, the adjacent window end face of the high-density graphite polystyrene insulation board 2, the base nail frame 7 and the adjacent part of the inner protective frame 8.

[0025] Specifically, the passive window installation base is further configured as follows: A corner guard 71 is first installed at the corner of the outer cement mortar leveling area 6 along the upper edge of the base, and then, as needed, an extended outer frame 8 is installed to cover the exposed part of the outer cement mortar leveling area 6 and its adjacent outdoor cement mortar leveling layer 5, forming a drip line 72. The outer end face of the outer cement mortar leveling area 6 along the lower edge of the base, extending outward from below the outer frame 8, is sloped with a higher inner slope and a lower outer slope. An expansion sealing strip 73 is used to install an upward-extending metal window sill 74 extending outside the wall, with the base of the metal window sill 74 pressed against the outer frame 8.

[0026] Specifically: the passive window frame 9 is embedded in the base frame 7 and the inner and outer protective frames 8 connected to it, as well as the sealing strips. The inner and outer substrates 70 of the PU rectangular base frame 7 are screwed onto the inner and outer protective frames 8 respectively. The window end face of the rectangular base frame 7 and the inner side of the window segment of the inner and outer protective frames 8 are embedded into the outer peripheral end face and inner and outer sides of the passive window frame 9 respectively by end face sealing strips 81 and inner and outer sealing strips 82. The inner and outer substrates 70 of the U-shaped cross section respectively wrap around the inner and outer ends of the rectangular base frame 7. The end face sealing strip is squeezed between the outer peripheral end face of the passive window frame 9 and the PU rectangular base frame 7 and any one of its substrates 70.

[0027] Specifically: the window ends of the inner and outer protective frames 8 are respectively secured to the passive window frame 9 by inner and outer sealing strips 82, and the window ends of the inner and outer protective frames 8 are secured to the inner and outer sealing strips 82 by grooves. More specifically: the window ends of the inner and outer protective frames 8 are respectively secured to the passive window frame 9 by inner and outer sealing strips 82, and the window ends of the inner and outer protective frames 8 are secured to the inner and outer sealing strips 82 by grooves. The thickness of the window ends of the inner and outer protective frames 8 on the side of the inner and outer connecting piece 52 is less than the thickness of the window ends of the corresponding inner and outer protective frames 8.

[0028] Specifically, after the passive window frame 9 is installed, the outer peripheral end face of the rectangular base nail frame 7 is pressed and bonded to the inner peripheral end face of the central convex ring and the adjacent window end faces of the inner and outer cement mortar leveling areas 6 on both sides.

[0029] Specifically, the steps for installing the passive window frame are as follows: 1) Screw the protective frame 8 on either the indoor or outdoor side to the base nail frame 7, and install it on the mounting base, and fix the protective frame 8 to the connecting piece 52 on that side; 2) Set the end face sealing strip 81 and the side sealing strip 82 on the window end face of the base nail frame 7 and the window end of the protective frame 8 on that side, respectively, and then press them into the passive window frame 9; 3) Screw the protective frame 8 on the opposite side with the opposite side sealing strip 82 to the base nail frame 7, laterally embed and press the passive window frame, and fix the side protective frame 8 to the connecting piece 52.

[0030] In summary, the present invention provides a stable and easily replaceable passive window installation method for zero-carbon buildings. The passive window is stable and easy to replace, and it remains stable after replacement. It will not fall in the event of a fire, and there is no thermal bridge after installation.
