Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a unit-type ultra-narrow concealed inward-opening door and window structure. Background Technology

[0002] In my country, the construction industry accounts for approximately half of the total energy consumption during construction and use. With the growing awareness of sustainable development, people are increasingly emphasizing the aesthetics and energy efficiency of buildings. The aim is to increase the thermal resistance of indoor and outdoor energy exchange while ensuring indoor thermal environment quality, thereby reducing the massive energy consumption of heating and air conditioning systems and achieving rational resource utilization and sustainable development. Aesthetically pleasing and energy-efficient doors and windows are crucial for building energy conservation. They are sensitive areas for energy gain and loss and are closely related to lighting, ventilation, sound insulation, and facade design. This places higher demands on improving the aesthetics and energy efficiency of doors and windows. The structural treatment around door and window frames mainly focuses on improving the thermal insulation performance of materials and enhancing the water tightness, air tightness, and wind pressure resistance of the doors and windows—important overall performance aspects of the building's exterior walls. Improving building performance through energy-efficient and safe doors and windows, thereby establishing a sound green, low-carbon, and circular economic system, and ensuring sustainable development towards carbon peaking and carbon neutrality goals, is the current trend in building energy conservation.

[0003] Due to increasingly stringent energy-saving requirements, modern door and window structures demand ever-wider cross-sectional widths, while the visible width of doors and windows is shrinking. This contradictory structural relationship places higher demands on the design and installation of doors and windows. Ultra-narrow door and window sashes are very stable because they are connected by glass structures on all four sides. However, the outer frames of ultra-narrow doors and windows are connected using traditional door and window subframe techniques. Because of the small visible surface, the total thickness of the materials is also small, which makes it impossible to achieve the structural strength of doors and windows as well as the high-precision sealing connection between the door and window sash and the frame.

[0071] The concealed drainage system for doors and windows in this embodiment, hereinafter referred to as ultra-narrow concealed drainage, is a current trend in door and window design. In addition to meeting various energy-saving and safety indicators, it is increasingly developing towards the aesthetics and simplification of doors and windows. This is because the ultra-narrow design concept is based on the visual effect of people inside and outside the room. Ultra-narrow means that the materials must be thin or small, but this violates the fatal design method of door and window structural safety. The system structure of this embodiment effectively solves the aforementioned problems.

[0072] This embodiment utilizes a unique side drainage structure design with concealed drainage channels. In extreme weather conditions, the side drainage structure's drainage function and effect are more than five times that of front drainage. Therefore, this structure plays a significant role in the drainage function of doors and windows, especially during extreme weather. Compared to the ultra-narrow concealed drainage structure design, existing doors and windows require multiple windproof and rainproof covers at the lower sill on the exterior side, typically made of plastic. This is especially true for dry-type door and window systems, where each section requires a windproof and rainproof cover. This structural method not only hinders the critical drainage function of doors and windows but also wastes labor and results in an unsightly appearance.

[0073] Example 2

[0074] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.

[0075] The ultra-narrow door and window system in this embodiment solves the critical structural problem of unstable and unreliable installation strength and precision of the ultra-narrow door and window frame and the ultra-narrow subframe system by using a special connection between the profile outer frame and the ultra-narrow subframe system pre-embedded in the building.

[0076] (1) Taking the unit-type ultra-narrow concealed door and window frame 1 as an example, hereinafter referred to as the ultra-narrow door and window frame.

[0077] Specifically, the width of the visible surface 10 on the inner side of the door and window frame is less than 10 mm, the width of the visible surface 12 on the outer side of the unit-type ultra-narrow concealed door and window frame is less than 43 mm; the width of the visible surface 11 on the inner side of the door and window sash is less than 52 mm, the width of the visible surface 13 on the outer side of the door and window sash is less than 24 mm; and the concealed groove 14 with the unit-type ultra-narrow concealed door and window frame.

[0078] This embodiment is based on its outermost groove and extends the design towards the wall connection direction. By making special settings for the installation requirements of the door and window outer frame in the door and window installation specifications and the installation system attached to the wall layer by layer, and guiding the associated construction procedures, it can completely solve various structural problems in the connection between the extremely narrow door and window outer frame and the wall.

[0079] (2) Extremely narrow door and window system

[0080] This embodiment provides a new setting and installation method for the matching of the groove of the outer frame profile of ultra-narrow doors and windows, the groove-entry sub-frame profile (hereinafter referred to as groove-entry sub-frame 3), and the hook sub-frame profile (hereinafter referred to as hook sub-frame 5). Furthermore, the groove-entry sub-frame 3 and the hook sub-frame 5 are fixed in the building construction wall 9 according to the building construction requirements before the doors and windows are installed. The hook sub-frame 5 of the ultra-narrow door and window system has a design and construction principle that is basically the same as the outer frame 1 of the ultra-narrow doors and windows and one side of the adjacent two side frames. The groove-entry sub-frame 3 at the bottom of the ultra-narrow door and window system has a design and construction principle that is basically the same as one side of the adjacent two side frames. The upper, lower, left, and right sides of the outer frame 1 of the ultra-narrow door and window system are designed with the contact installation parts of the hook sub-frame 5, groove-entry sub-frame 3, and outer frame profile to give it the function of a multi-functional integrated ultra-narrow door and window system.

[0081] The upper hook subframe 5 and the side groove subframe 3 of the ultra-narrow door and window system are structurally constructed as an L-shaped group on both sides; the lower groove subframe 3 and the hook subframe 5 on the other side are structurally constructed as another L-shaped group. The two L-shaped combinations form the rectangle of the door and window outer frame. In actual operation, the structural positions of the left and right hook subframes 5 and the groove subframe 3 of the door and window outer frame 1 can be interchanged, as long as the design is compatible. The design positioning of the upper hook subframe 5 and the lower groove subframe 3 cannot be changed.

[0082] The upper hook subframe 5 of the ultra-narrow door and window system and the side groove subframe 3 are an L-shaped set on both sides; the lower groove subframe 3 and the other side hook subframe 5 are another L-shaped set. The two L-shaped combinations form the rectangle of the outer frame of the door and window.

[0083] (3) The design and working principle relationship between the upper, lower, left, and right sides of the ultra-narrow door and window system and its connection with the splicing pipe:

[0084] a. Upper part of the ultra-narrow door and window system: The outermost groove of the outer frame of the door and window frame 1 is used to install an outer groove of the outer frame 1, an upper door and window frame, and a subframe connector 6 connecting the inner and outer structures of the subframe; a door and window frame 1 and a subframe adapter 7; the door and window frame 1, the subframe connector 6 connecting the inner and outer structures of the subframe, the second subframe adapter 7 connecting the door and window frame and the subframe structure, and the subframe connector 8 are connected by connecting bolts 8 to lock the relationship between the various components into a unified whole structure. Because the hook subframe 5 has already been fixed in the wall 9 of the building construction according to the basic requirements of building construction before the door and window installation, the subsequent process does not require layout and positioning. Therefore, only foaming agent gap filling and sealant treatment are needed to complete the upper door and window installation.

[0085] b. Lower part of the ultra-narrow door and window system:

[0086] The first subframe adapter 4 is inserted into the groove of the lower door / window outer frame 1; the groove of the first subframe adapter 4 is then inserted into the groove of the grooved subframe 3, connecting the door / window outer frame 1, the first subframe adapter 4, and the grooved subframe 3 into a unified whole structure. Because the grooved subframe 3 profile was already fixed in the wall 9 of the building construction according to the basic requirements of building construction before the door / window installation, the subsequent process does not require layout and positioning. Therefore, only sealing with caulking is needed to complete the installation of the lower door / window.

[0087] c. Left and right sides of the ultra-narrow door and window system:

[0088] The left and right sides of the ultra-narrow window and door system can use the installation structure set at the bottom of the ultra-narrow window and door system on one side or the installation structure set at the top of the ultra-narrow window and door system on the other side. Each side of the ultra-narrow window and door system has one set of L-shaped structures, and the two L-shaped structures are combined to form the outer frame of the window and door.

[0089] With the implementation of the concept of sustainable development and the rapid development of my country's construction industry, the living standards of the Chinese people and the increasing standards for building energy conservation and safety are rising. To improve construction quality, the overall quality of exterior doors and windows, especially the installation process, is becoming increasingly important. Traditional door and window installation methods urgently need to be changed. The doors and windows in this embodiment achieve innovative installation technology, which significantly improves the construction quality of the door and window industry and has a very important impact on the aesthetics, safety, performance, energy conservation, environmental protection, and maintenance of the overall building.

[0090] Technical problems with existing door and window installation methods in traditional buildings:

[0091] a. Disadvantages of using waterproof mortar as a filler for the gaps between the exterior wall and the aluminum door and window frames: Waterproof mortar, being a non-elastic structure, makes direct hard contact with the door and window frames, causing cracks in the gaps after filling. Even when sealant is used, the gaps are prone to deformation and cracking due to the incompatibility between the sealant and the waterproof mortar, resulting in water seepage.

[0092] b. Disadvantages of using waterproof cloth as a filler for the gaps between the exterior wall and the aluminum door and window frames: complicated operation, high cost, uneconomical, and poor waterproof effect;

[0093] c. Advantages and disadvantages of steel subframes: They provide a painting benchmark and reduce the overlap time between the main frame and other trades; they are a post-installation method for doors and windows, which is beneficial for the protection of finished doors and windows. However, the construction method of steel subframes is prone to displacement due to the gap between the steel frame and the outer frame of the door and window, which is filled with foaming agent and sand. This can cause water seepage in the subframe, peeling and rusting of the galvanized layer of the steel frame, which in turn can cause cracking of the sealant between the subframe and the window frame, resulting in water seepage around the window frame and tilting of the window frame, leading to a series of safety problems for the window. The use of screws for fixing also damages the integrity of the outer frame cavity of the door and window.

[0094] d. Advantages and disadvantages of wood-plastic energy-saving ultra-narrow door and window system: Compared with steel ultra-narrow door and window system, it does not rust or corrode, but it is not economical and is not waterproof;

[0095] e. Advantages and disadvantages of post-installed male and female clip iron plate installation: This method of post-installation of doors and windows is beneficial for the protection of finished doors and windows. However, it requires high precision in the plastering of exterior wall door and window openings, the installation strength may not meet standards, and it is not waterproof.

[0096] f. Due to the large scale of the construction industry in recent years, the state has mandated the increase of prefabricated buildings (hereinafter referred to as PC) to improve energy conservation. However, the installation of doors and windows in PC designs is still based on traditional methods due to the high level of specialization, which violates the original design intention of PC buildings. The design scheme of this system effectively solves this problem.

[0097] g. With the continuous improvement of national technical and performance requirements for doors and windows, and the actual demand of the general public for secondary renovation of houses, replacing doors and windows is a difficult problem, especially for high-rise buildings with poor construction quality and long history. If the construction is not properly controlled during the secondary demolition and reconstruction of doors and windows, the original cement materials of the building walls may fall from the height, which will bring serious economic, social and even life safety problems to the general public and residents themselves.

[0098] Because the hook frame 5 and slotted frame 3 in this embodiment are fixed in the wall 9 of the building construction according to the basic requirements of building construction before the installation of doors and windows, they have become an integral part of the building structure. Furthermore, the hook frame 5 and slotted frame 3 in this embodiment adhere to the universality and standardization of the slot design for the outer frame of existing and future building doors and windows. Therefore, repairing or replacing doors and windows is a subsequent process and does not require wall demolition or layout positioning. Using the ultra-narrow door and window system installation method can completely solve the problem of secondary door and window repair and replacement for home renovations and the general public.

[0099] This embodiment provides a unitized, ultra-narrow, concealed, inward-opening door and window structure:

[0100] The doors and windows used in this embodiment are mainly characterized by the high-precision structural connection between the door and window subframes embedded in the wall and the outer frame of the ultra-narrow door and window system. Specifically, due to increasingly higher energy-saving requirements, modern door and window structures require increasingly larger cross-sectional widths, but the width of the visible surface of the doors and windows is becoming increasingly smaller. This contradictory structural relationship places higher demands on the design and installation of doors and windows. Ultra-narrow door and window sashes are very stable because of the glass structure on all four sides. However, if the outer frame of the ultra-narrow door and window is connected using the traditional door and window subframe process, the total thickness of the material is also small due to the small visible surface, which cannot achieve the structural strength of the door and window and the high-precision sealing connection between the door and window sash and frame.

[0101] The doors and windows used in this embodiment completely solve the problems of waterproofing between the door and window frames and the wall, inaccurate installation and positioning measurements, finished product protection in buildings with pre-installation construction methods, unreliable installation connection strength between the door and window frames and the wall, and the large amount of waste of labor, sealant, foaming agent, screws, and other materials between the door and window frames and the wall.

[0102] In this embodiment, the quality of the installation and connection points around the doors and windows directly affects the overall installation quality, and these areas are also the most prone to leakage. The ultra-narrow door and window system effectively solves this problem. Its unique structure ensures a clear interface between the door and window contractor and the civil engineering contractor, and clearly identifies the locations of the civil engineering leveling points.

[0103] This embodiment utilizes the method of directly applying sealant (sealing adhesive on both sides of the inner and outer walls of the doors and windows) to the aluminum alloy profiles on the outer side of the door and window frames and the aluminum wall surface of the subframe. This solves the unscientific and difficult-to-solve construction problems caused by the incompatibility of materials due to the direct connection between the sealant and the exterior wall mortar in the original traditional construction method, such as cracking, curling, and water seepage.

[0104] The seamless design of the ultra-narrow window and door system profiles extends the original sealed cavity of the window and door frame into the wall, creating another sealed cavity. This effectively adds a sealed cavity between the window and door frame and the wall, increasing the thickness of the original frame material and merging two previously separate components into a unified height. The advantages of designing an ultra-narrow window and door system based on this principle are mainly reflected in:

[0105] 1) The connection between the outer frame of the doors and windows and the wall of the ultra-narrow door and window system increases the thickness of the material and forms an integral part of the building, making the raw materials stronger and achieving a more beautiful appearance.

[0106] 2) The extension design of the waterproof positioning bars on both sides of the subframe and the waterproof reinforcing bars in the middle subframe is led to the building wall through the two long sides of the insert-type ultra-narrow door and window system, so that the two originally independent and separate individual building heights of the door and window frame and the wall are integrated into one, forming a sealed building component that integrates heat preservation, heat insulation, waterproofing, positioning and connection.

[0107] 3) Through the design of the profile cross-section channels and various surfaces, the project allows for both pre-installation (a professional term referring to the method of installing the door and window frame before the building construction and wall painting) and post-installation (a professional term referring to the method of installing the door and window frame after the building construction and wall painting) during construction. This plays a positive role in protecting the finished door and window products, solves a series of problems such as dirt and mess after on-site installation of door and window frames, as well as serious material deformation and paint peeling, and saves a lot of packaging materials.

[0108] 4) The multi-clamp connection installation method of the ultra-narrow door and window system embedded in the building wall greatly enhances the strength of the ultra-narrow door and window system.

[0109] 5) The surface design of the ultra-narrow door and window system solves the contact difficulties between the door and window frame and the building surface in traditional construction. This is because the ultra-narrow door and window system uses materials that are compatible with the door and window frame profiles, resulting in a high degree of integration between the frame material and the building structure. This plays a crucial role in the connection strength, insulation, and sealing performance between the two.

[0110] 6) The ultra-narrow door and window system utilizes the straight contact surface and 90-degree angle principle of the outer frame profile and the sub-frame profile to completely solve the industry problem of uneven, non-straight, and unsightly surface of the sealant between the original exterior wall doors and windows, thus improving the construction effect of the exterior wall doors and windows.

[0111] 7) The ultra-narrow door and window system has a significant height difference at the top, bottom, left and right sides because the design itself is higher than the finished surface of the exterior wall structure. Therefore, even if the original product delaminates, this structure will still have excellent waterproof performance by utilizing the height difference.

[0112] 8) The slot design of the ultra-narrow door and window system subframe allows for quick and efficient automatic positioning, fixing, and connection during installation.

[0113] 9) The four corner joints of the subframe of the ultra-narrow door and window system are all tightly sealed, which improves the overall airtightness of the ultra-narrow door and window system.

[0114] 10) The ultra-narrow window and door system can meet the design and construction process requirements of various exterior and interior walls.

[0115] 11) The ultra-narrow door and window system is very economical and environmentally friendly because of its compact structure and simple installation, which can save a lot of labor and materials.

[0116] 12) For ultra-narrow door and window systems, the installation of the entire frame door and window, except for the connection of the four corner connectors of the subframe and the connection of the subframe iron feet to the civil wall, does not require any screws to be used for fastening anywhere else.

[0117] 13) The ultra-narrow door and window system completely disconnects the connection between the door and window and the subframe with heat insulation material, blocking heat exchange and meeting energy-saving design requirements.

[0118] 14) When using the ultra-narrow window and door system, the installation of the window and door frame does not require the completion of the civil engineering work, such as laying out, positioning, and measuring. This is because the subframe has already been positioned and installed according to the building construction requirements in the previous process. The subsequent process can simply be the slotting and fastening. Compared with the traditional installation method, this saves a lot of workers' installation time.

[0119] 15) The subframe channel is made of the same aluminum material as the doors and windows. The overall design has advantages that cannot be replaced by other traditional subframes.

[0120] 16) The aluminum material rib buckle design and the rib height difference design of the ultra-narrow door and window system passage not only increase the strength of the frame, but also strengthen the integrity with the civil engineering wall, making the frame more solid and stable.

[0121] Except for the four corner connectors of the subframe, the iron feet of the subframe, and the connection with the civil engineering wall, all materials used in the ultra-narrow door and window system do not require drilling in any other installation parts, which strictly ensures the overall design performance requirements of the door and window.

[0122] This embodiment discloses a unit-type ultra-narrow concealed inward-opening door and window structure and an installation connection structure design and installation method between the door / window wall and the structure.

[0123] This mainly includes: the design and installation method of the connection structure between the existing unitized door and window subframe structure and the surrounding wall, and the installation connection structure between the door and window outer frame and the door and window subframe of the unitized ultra-narrow concealed inward opening door and window structure, hereinafter collectively referred to as the ultra-narrow door and window system.

[0124] This embodiment can solve the long-standing industry problems of unclear work boundaries, unclear work responsibilities, and unclear economic responsibilities between construction companies and door and window installation companies.

[0125] The ultra-narrow door and window system in this embodiment satisfies the versatility of both pre-installation and post-installation construction methods for doors and windows in engineering, greatly improves the quality of building door and window products, effectively realizes the integrated structural design of existing door and window outer frame cavities and cavity materials pre-installed in building walls, and this system maintains the versatility of the original building doors and windows.

[0126] Compared to traditional installation methods, the ultra-narrow door and window system in this embodiment is mainly characterized by the high-precision structural connection between the door and window subframes embedded in the wall and the outer frame of the ultra-narrow door and window system. Specifically, due to increasingly higher energy-saving requirements, modern door and window structures require larger cross-sectional widths, but the visible width of the doors and windows is becoming smaller. This contradictory structural relationship places higher demands on the design and installation of doors and windows. The ultra-narrow door and window sashes are very stable because of the glass structure on all four sides. However, the ultra-narrow door and window outer frame is connected using the traditional door and window subframe process. Because the visible surface is small, the total material thickness is also small, which cannot achieve the structural strength of the door and window and the high-precision sealing connection between the door and window sash and frame. Therefore, the ultra-narrow door and window system in this embodiment not only solves this problem, but also saves a lot of materials and labor, and achieves a high-strength connection between the ultra-narrow door and window structure and the surrounding wall. It is absolutely waterproof, firmly installed, and easy to operate.

[0127] The doors and windows in this embodiment combine aesthetics, safety, waterproofing, heat insulation, energy saving, environmental protection, and high efficiency, overturning the traditional door and window installation methods of the past few years. This will promote the personalized development of the door and window industry and have positive social and economic benefits.

[0128] This invention solves the critical structural problem of unstable and unreliable installation strength and precision of ultra-narrow door and window frames and ultra-narrow subframe systems.
