Description

Technical Field

[0001] This application relates to the field of window frame construction, and more particularly to a window frame construction process in passive buildings. Background Technology

[0002] Passive buildings, also known as passive houses, are energy-efficient buildings constructed based on passive design principles. Passive houses can regulate the indoor temperature to a comfortable level with very little energy consumption, making them very environmentally friendly.

[0003] Passive houses typically use insulated wall panels for their exterior walls, and window frames are usually installed externally on these panels. During installation, window frames are mostly connected to the insulated wall panels via steel angle brackets. Heat from the insulated exterior wall is conducted through these brackets, resulting in heat loss and requiring improvement. Summary of the Invention

[0004] To reduce heat loss from insulated exterior walls, this application provides a window frame construction process for passive buildings.

[0005] The technical solution provided in this application for a window frame construction process in passive buildings is as follows: A window frame construction process for passive buildings, used to install window frames onto insulated walls, includes the following steps: opening door / window openings in the insulated wall; marking vertical and horizontal lines on the insulated wall around the perimeter of the door / window openings using a chalk line; installing connectors with insulating pads onto the insulated wall at intervals along the vertical markings, with the side of the connector with the insulating pad facing the insulated wall; supporting the window frame and connecting the window frame to each connector in sequence; and sealing the gap between the window frame and the insulated wall with a waterproof membrane.

[0006] By adopting the above technical solution, during the installation of the connectors onto the insulated wall, the connectors and the insulated wall are isolated by an insulation pad, making it difficult for heat from the insulated wall to transfer to the connectors, thus reducing heat loss from the insulated wall. The insulated wall reduces indoor-outdoor heat exchange, which improves the cooling efficiency of air conditioning, reduces energy consumption, and saves a significant amount of wall material, thus embodying the concept of energy conservation and environmental protection.

[0007] Preferably, before installation, the dimensions of the door / window and window frame are measured, with the door / window size being larger than the window frame size, and the dimensional difference between the door / window and window frame being ≤5mm.

[0008] By adopting the above technical solution, the size of the door and window is set to be larger than the size of the window frame. After the window frame connector is installed on the heat insulation wall, the window frame and the heat insulation wall are spaced apart, reducing the structure between the window frame and the heat insulation wall. This makes it difficult for heat from the heat insulation wall to be transferred to the window frame, which helps to reduce heat loss from the heat insulation wall.

[0009] Preferably, the connectors are distributed on the heat-insulating wall along the hammer marks by the positioning element. The positioning element is provided with a guide ruler parallel to the vertical mark. Several guide blocks are slidably connected to the guide ruler. The guide blocks press against the connectors, so that the connectors slide against the window frame in a direction parallel to the horizontal mark and are connected to the window frame.

[0010] By adopting the above technical solution, in the actual installation process, the positioning component is sequentially fitted with a guide ruler, a connector, and a heat insulation pad. The guide block is moved so that it abuts against the side of two adjacent connectors that are close to each other. Then, the window frame is supported between several connectors. The connector is moved closer to the window frame, and the guide block abuts against the connector, so that the connector remains flush with the horizontal mark line during the movement until the connector abuts against the window frame, thus fixing the window frame and the connector. This helps to ensure the verticality of the window frame after the window frame and the connector are fixed.

[0011] Preferably, the drive block is inserted onto the guide ruler, and the drive block moves and engages between two adjacent guide blocks, so that the two adjacent guide blocks move against each other and press against the connecting piece.

[0012] By adopting the above technical solution, during the actual installation process, the drive block is inserted between two adjacent guide blocks, so that the two guide blocks move towards the connector and press against the connector, making it convenient to position the guide block.

[0013] Preferably, after the window frame is connected to the connector, the guide ruler is moved close to the window frame to fill the gap between the window frame and the insulated wall.

[0014] By adopting the above technical solution, after fixing the window frame and connectors, the guide ruler is moved close to the window frame so that it enters the gap between the window frame and the thermal insulation wall, which helps to improve the stability of the window frame installation.

[0015] Preferably, the load-bearing blocks are installed on the insulated wall along the direction of the horizontal marking line, and the window frame is supported by the load-bearing blocks.

[0016] By adopting the above technical solution, the load-bearing block is installed on the heat-insulating wall along the horizontal marking line, and then the window frame is supported on the load-bearing block, which helps to maintain the horizontality of the window frame.

[0017] Preferably, the windowsill is installed between the load-bearing block and the window frame.

[0018] By adopting the above technical solution, the window frame is installed on the heat-insulating wall, and the window sill is installed between the load-bearing block and the window frame, which reduces the erosion of the load-bearing block and the waterproof membrane below the window frame by rainwater flowing from the window frame.

[0019] Preferably, the insulated walls and window frames are cleaned of dust before the waterproof membrane is installed.

[0020] By adopting the above technical solution, cleaning the insulated walls and window frames before installing the waterproof membrane helps the waterproof membrane adhere tightly to the insulated walls and window frames.

[0021] Preferably, the waterproof membrane on the inside of the window frame is pre-applied to the window frame before installation, and the waterproof membrane protruding from the frame is fixed with tape.

[0022] By adopting the above technical solution, after the window frame and connectors are installed, the inner side of the window frame is close to the inner wall of the door and window, making it inconvenient to apply a membrane to the inner side of the window frame. By pre-applying the waterproof membrane to the inner side of the window frame, it is convenient to install the waterproof membrane on the inner side of the window frame.

[0023] Preferably, the waterproof membrane is smoothed using a scraper.

[0024] By adopting the above technical solution, after the gap between the window frame and the heat insulation wall is covered with a waterproof membrane, the pasted waterproof membrane is smoothed with a screed, so that the waterproof membrane can better adhere to the heat insulation wall and the window frame.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. During the installation of the connectors into the insulation wall, the connectors and the insulation wall are isolated by the insulation pad, making it difficult for heat from the insulation wall to be transferred to the connectors, which helps to reduce heat loss from the insulation wall. 2. Set the size of the door and window to be larger than the size of the window frame, so that after the window frame connector is installed on the thermal insulation wall, there is a gap between the window frame and the thermal insulation wall. This reduces the structure between the window frame and the thermal insulation wall and helps to reduce heat loss from the thermal insulation wall. 3. After fixing the window frame and connectors, move the guide ruler close to the window frame so that it enters the gap between the window frame and the insulated wall. This helps to improve the stability of the window frame installation. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a window frame construction process in passive buildings. (Refer to...) Figure 1 A window frame installation process in passive buildings, used to install window frame 2 onto insulated wall 1, includes the following steps: A rectangular door / window 11 is opened on the insulated wall 1. The horizontal and vertical dimensions of the door / window 11 are measured with a tape measure and compared with the horizontal and vertical dimensions of the window frame 2. The size of the door / window 11 should be larger than the size of the window frame 2. The difference between the size of the door / window 11 and the size of the window frame 2 should be ≤5mm. In this embodiment, the size of the door / window 11 is 4mm larger than the size of the window frame 2.

[0031] Fix the string line vertically to the insulation wall, and use a level to check the verticality of the string line. After confirming that the verticality is correct, use the string line to leave vertical marking lines on both sides of the door and window 11. Fix the string line horizontally to the insulation wall, and use a level detector to check the horizontality of the string line. After confirming that the horizontality is correct, use the string line to leave horizontal marking lines below the door and window 11.

[0032] Prepare several connectors 3 for fixing the window frame 2. Each connector 3 includes a mounting part 31 and a connecting part 32. The mounting part 31 is used to fix the window frame 2 to the heat insulation wall 1, and the connecting part 32 is used to fix the window frame 2 to the wall 2. The connecting part 32 is located at one end of the mounting part 31 and is integrally formed with the mounting part 31. The connecting part 32 and the mounting part 31 are assembled into an "L" shape. In this embodiment, the connector 3 is an angle bracket steel.

[0033] The mounting part 31 has a first positioning opening 311 and several second positioning openings 312. The first positioning opening 311 is elongated, and the second positioning openings 312 are located on the side of the first positioning opening 311 away from the connecting part 32. The length direction of the first positioning opening 311 is parallel to the horizontal marking line, and the distribution direction of the first positioning opening 311 and the second positioning openings 312 is also parallel to the horizontal marking line. Several positioning components 4 are prepared for positioning the mounting part 31. The number of positioning components 4 corresponds one-to-one with the number of connecting parts 3. The positioning components 4 are used to pass through the corresponding positioning openings 311 and are fixed to the heat insulation wall 1. The positioning components 4 are initially positioned against the side of the mounting part 31 away from the heat insulation wall 1, and the positioning components 4 can move along the length direction of the positioning opening 311. In this embodiment, the positioning component 4 is an expansion screw.

[0034] Reference Figure 2 Prepare several heat insulation pads 33. The shape of the heat insulation pads 33 is consistent with the shape of the mounting part 31. The position and number of the heat insulation pads 33 correspond one-to-one with the position and number of the connectors 3.

[0035] Prepare several guide rulers 5. The guide rulers 5 are used to abut against the side of the installation part 31 away from the heat insulation wall 1. The end of the guide ruler 5 near the window frame 2 is used to abut against the window frame 2. The length direction of the guide ruler 5 is parallel to the vertical mark line. The guide ruler 5 has a long strip opening 51 and several guide openings 52. The guide openings 52 and the long strip openings 51 are spaced apart. The number of guide openings 52 is the same as the number of positioning openings 311 located on the same side of the door and window 11. The guide openings 52 are for corresponding positioning parts 4 to pass through. The positioning parts 4 slide and connect with the guide ruler 5 along the length direction of the guide openings 52. When several positioning parts 4 abut against the inner wall of the guide openings 52 near the window frame 2, the positioning parts 4 and the long strip openings 51 are both located on the vertical mark line.

[0036] The guide ruler 5 has several elongated openings 53, the length of which is parallel to the length of the first opening 51. Several guide blocks 54 are slidably connected to the guide ruler 5. The guide blocks 54 protrude from the guide ruler 5 towards the insulation wall 1, positioning the connector 3 on the moving path of the guide blocks 54. The end face of the guide blocks 54 near the connector 3 is parallel to the horizontal marking line. Drive blocks 55 are inserted into the elongated openings 53, positioned between adjacent connectors 3. Guide blocks 54 are located on opposite sides of the drive blocks 55, distributed vertically. Guide surfaces 551 are machined on the opposite ends of the drive blocks 55, inclined towards each other towards the insulation wall 1. The guide surfaces 551 abut against the guide blocks 54, causing the guide blocks 54 to move and press against the side of the connector 3 closest to the guide blocks 54. The guide ruler 5 is spaced apart from the insulation wall 1.

[0037] Place the heat insulation pad 33 on the side of the corresponding mounting part 31 closest to the heat insulation wall 1. Place the guide ruler 5 on the side of the mounting part 31 away from the heat insulation pad 33. The positioning element 4 is inserted through the guide ruler 5, the mounting part 31, and the heat insulation pad 33 in sequence to initially position the connector 3. The connector 3 after initial positioning is evenly distributed on the opposite sides of the door and window 11. The connector 3 on the same side of the door and window 11 are evenly distributed along the vertical marking line. Several positioning elements 4 are all located on the vertical marking line. When the positioning element 4 abuts against the inner wall of the guide opening 52 on the side away from the window frame 2, the elongated opening 51 is also located on the vertical marking line. Insert the driving block 55 into the elongated opening 53 in the direction closer to the heat insulation wall 1 so that the guide block 54 fits against the corresponding mounting part 31. Adjust the mounting part 31 to be horizontal.

[0038] Prepare several load-bearing blocks 6 and fix them to the heat insulation wall 1 with expansion screws. The load-bearing blocks 6 are used to support the window panel. The lower end of the load-bearing blocks 6 is parallel to the horizontal mark line so that the upper end of the load-bearing blocks 6 after installation is kept horizontal, which helps to ensure the horizontality of the window frame 2 when it is supported on the load-bearing blocks 6.

[0039] After installing the load-bearing block 6, use a blower to clean the surface of the window frame 2 and the inner wall of the mounting bed. Pre-apply the prepared waterproof membrane to the flat areas of the window frame 2, ensuring the membrane surrounds the outer circumference. After rounding the corners at bends, use a scraper to smooth the membrane, ensuring a secure connection. Then, secure the membrane at the rounded corners with tape. Place the window frame 2 with the pre-applied waterproof membrane onto the load-bearing block 6, positioning it between the two connecting parts 32. Move the mounting part 31 closer to the window frame 2, ensuring the connecting part 32 fits against the window frame 2. Guide the mounting part 31 using the guide block 54, moving it parallel to the horizontal marking line. Keep the side of the connecting part 32 closest to the window frame 2 vertical. Ensure the verticality of the window frame 2 by ensuring the two connecting parts 32 fit and press firmly against it. This helps guarantee the horizontal and vertical alignment of the window frame 2, eliminating the need for additional testing. In this embodiment, the window frame 2 and the connecting part 32 are fixed with expansion bolts.

[0040] After fixing the window frame 2 to the connecting part 32, expansion bolts are inserted through several positioning holes 312 to fix the thermal insulation wall 1 and the mounting part 31, thereby fixing the window frame 2. After fixing, the driving block 55 is removed, and the guide ruler 5 is moved towards the window frame 2 to fill the gap between the window frame 2 and the thermal insulation wall 1, thereby increasing the positioning stability of the window frame 2.

[0041] Unfold the waterproof membrane pre-installed on the window frame 2 and stick it to the inner wall of the door and window 11. Use a screed to smooth the waterproof membrane and make it stick firmly.

[0042] The insulation wall 1 surrounding the door and window 11 is cleaned using a blower. After cleaning, the gap between the window frame 2 and the insulation wall 1 is sealed using a prepared waterproof membrane. The bottom of the window frame 2 is sealed first, then the sides of the window frame 2 are sealed, and finally the top is sealed. During the sealing process, the waterproof membrane covers the load-bearing block 6, connector 3, and guide ruler 5 to protect them and prevent rainwater from corroding them. In this embodiment, the waterproof membrane pre-adhered to the window frame 2 is a waterproof and airtight membrane, while the waterproof membrane adhered outdoors to seal the gap between the window frame 2 and the insulation wall 1 is a waterproof and breathable membrane.

[0043] The prepared window sill is fixed to the window frame 2 with expansion bolts, so that the window sill is located between the window frame 2 and the load-bearing block 6.

[0044] The implementation principle of the window frame construction process in a passive building according to the embodiments of this application is as follows: when the window frame 2 is installed on the thermal insulation wall 1, the connector 3 and the thermal insulation wall 1 are separated by the thermal insulation wall 1, and the thermal insulation wall 1 and the installed window frame 2 are spaced apart to reduce thermal bridges on the thermal insulation wall 1 and reduce heat loss on the thermal insulation wall 1.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
