Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular discloses a door and window structure for buildings. Background Technology

[0002] In the field of building doors and windows, traditional structures often face the problem of balancing load-bearing capacity and energy-saving performance. A single material must simultaneously meet the functions of load-bearing and thermal insulation, which leads to limited material selection, increased costs, and difficulty in achieving balanced performance. For example, heavy concrete, while ensuring strength, is insufficient in thermal insulation and requires an additional insulation layer, while lightweight materials have limited load-bearing capacity and cannot meet the needs of high-rise buildings. Traditional connection methods (bolted connections, on-site casting) have defects such as low construction efficiency and poor reliability. Bolts are prone to loosening and displacement, and on-site casting requires wet work, has a long cycle, and is difficult to control precision. In large-scale construction, the degree of standardization is prominent. Traditional window designs mostly use single-leaf operable windows or fixed windows, which separate ventilation and lighting functions. Users have difficulty adjusting them flexibly and cleaning and maintenance are inconvenient. The sealing performance is affected by frequent opening and closing, which can easily lead to increased energy consumption and noise intrusion. Existing technologies urgently need a building door and window structure that can separate load-bearing capacity and energy saving, has a stable and efficient connection, and is flexible and practical in function to improve overall performance and reduce costs.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figures 1 to 4 As shown, this utility model discloses a building door and window structure, including a door and window frame 1 and a wall structure. The door and window frame 1 is installed on the wall structure. The wall structure includes a first concrete layer 2 connected to the door and window frame 1 and a second concrete layer 3 disposed at the upper and lower ends of the first concrete layer 2 in the vertical direction. The first concrete layer 2 is a vertical load-bearing structure on both sides of the door and window, and the vertical load-bearing structure is a steel skeleton structure. The second concrete layer 3 is made of lightweight porous non-load-bearing material.

[0026] The steel reinforcement skeleton structure improves the shear and bending resistance of the wall through the coordinated work of the steel reinforcement skeleton (longitudinal reinforcement + stirrups) and concrete, providing load-bearing and deformation-resistant support for the door and window frame 1; the second concrete layer 3 utilizes internal pores to achieve thermal insulation and sound insulation, and the two together constitute a load-bearing-energy-saving dual-effect composite structure.

[0027] In practical use, firstly, the first concrete layer 2 serves as the vertical load-bearing structure on both sides of the doors and windows. It adopts a steel skeleton structure, in which the steel skeleton composed of longitudinal bars and stirrups works in conjunction with the concrete. The longitudinal bars can effectively bear the tensile force, while the stirrups restrain the deformation of the concrete, which greatly improves the shear and bending resistance of the wall. It provides a stable load-bearing and deformation-resistant support for the door and window frame 1, enhances the structural rigidity at the door and window openings, and can effectively resist external forces such as wind loads and seismic forces. It is especially suitable for high-rise buildings, buildings with high wind pressure, or buildings in seismic fortification areas, reducing the risk of cracking and deformation of the walls around the doors and windows, and ensuring the safety and stability of the doors and windows for long-term use.

[0028] Secondly, the second concrete layer 3 is made of lightweight, porous, non-load-bearing material. Its internal pores form an air insulation layer, effectively blocking heat transfer and achieving high-efficiency thermal insulation, thus reducing building energy consumption. Simultaneously, the porous structure absorbs and reflects sound waves, significantly improving sound insulation and creating a quiet and comfortable indoor environment. Furthermore, the lightweight material reduces the overall weight of the wall, lowering the load requirements on the foundation, saving on foundation construction costs, and facilitating construction through prefabrication or rapid casting, improving construction efficiency. The combined load-bearing and energy-saving design avoids the complex procedures of adding additional insulation and soundproofing layers required in traditional structures, reducing material and labor costs. This achieves an integrated and efficient design that combines structural load-bearing capacity with building energy conservation, combining technological advancement with economic rationality.

[0029] Specifically, the first concrete layer 2 is provided with a window sill capping embedded part 11 and a window side frame embedded part 12. The window sill capping embedded part 11 is connected to the window side frame embedded part 12, and the window sill capping embedded part 11 is set close to the second concrete layer 3. The window sill capping embedded part 11 and the window side frame embedded part 12 are connected by welding, and the weld height is 6mm.

[0030] In practical use, welding, as a rigid connection method, enhances structural strength by enabling the embedded parts 11 of the window sill cap and 12 of the window side frame to form a solid whole, eliminating gaps between the connecting parts and ensuring the continuity and efficiency of load transfer. The 6mm weld height is scientifically designed to ensure the strength of the welded area while avoiding material waste and stress concentration due to excessive weld height. Through welding, the wind load and self-weight borne by the door and window frame 1 can be quickly and stably transferred through the embedded parts to the steel reinforcement and concrete of the first concrete layer 2, significantly enhancing the structural integrity and deformation resistance of the door and window installation area, ensuring the safety of the building in complex environments and under long-term use. From the perspective of construction quality and reliability, the welding connection process is mature and controllable. The clearly defined 6mm weld height provides a precise standard for construction, facilitating standardized operation and quality inspection by construction personnel.

[0031] Compared to other connection methods, welding effectively reduces errors and uncertainties during construction, lowers the risk of quality problems caused by weak connections, ensures that every embedded part of the door and window meets design requirements, and improves the overall construction quality. Furthermore, welded embedded parts have good durability and are not easily loosened by environmental factors, reducing maintenance and replacement costs due to connection failures later. In terms of sealing and functionality, robust welded connections effectively prevent gaps at the embedded parts joints. Combined with other design elements of the door and window structure, this further enhances the sealing of the door and window area, reduces heat loss and noise penetration, and improves the building's thermal insulation and soundproofing performance, creating a more comfortable and energy-efficient indoor environment for users. This fully demonstrates the important role of architectural detail design in achieving functionality and ensuring quality.

[0032] Specifically, the wall structure is provided with an inner wall frame 4 that is installed in conjunction with the door and window frame 1. The inner wall frame 4 is provided with a first installation component 5 connected to the wall structure and a second installation component 6 connected to the door and window frame 1. The first installation component 5 is provided with a first locking part 51, and the second installation component 6 is provided with a second locking part 61 that cooperates with the first locking part 51. The first installation component 5 and the second installation component 6 are engaged by the first locking part 51 and the second locking part 61.

[0033] In practical use, considering ease of installation, the snap-fit ​​design of the first snap-fit ​​part 51 and the second snap-fit ​​part 61 allows for the assembly of the first installation component 5 and the second installation component 6 without complex tools or cumbersome operations. Construction workers can quickly complete the initial positioning and connection of the inner wall frame 4 and the door and window frame 1, significantly shortening construction time and improving installation efficiency, which is especially suitable for large-scale building construction scenarios. In terms of structural stability, the interlocking relationship formed by the snap-fit ​​structure ensures a tight connection between the inner wall frame 4, the wall structure, and the door and window frame 1, effectively dispersing the external forces on the doors and windows and preventing displacement or shaking of the door and window frame 1 during use. At the same time, this connection method also enhances the overall cooperative stress-bearing capacity of the doors and windows and the wall, improving the seismic performance and the ability to resist external loads of the building structure.

[0034] In terms of flexibility and adaptability, the snap-fit ​​structure is easy to adjust and disassemble. When repairs or replacements of doors and windows are needed, or when the position of doors and windows needs to be adjusted due to changes in building function, the first installation component 5 and the second installation component 6 can be easily separated without damaging the wall structure, reducing maintenance costs and construction difficulty. Furthermore, by adjusting the size and shape of the snap-fit ​​structure, it can adapt to different specifications of door and window frames 1 and wall structures, improving the versatility and practicality of the design. In addition, the snap-fit ​​structure can reduce gaps caused by loose connectors, enhance the sealing of door and window areas, further improve the building's thermal insulation and sound insulation effects, and achieve a unity of functionality and practicality.

[0035] Specifically, the locking part is a protrusion, a recess or a combination thereof that is fixedly connected to the door and window frame 1 or the inner frame 4 of the wall; the first locking part 51 is arranged in the vertical direction of the door and window frame 1, and the protrusion and the recess cooperate with each other to form a locking node to limit the relative displacement between the door and window frame 1 and the wall structure.

[0036] In practical use, from a mechanical performance optimization perspective, the vertically arranged protruding and recessed interlocking nodes provide strong vertical restraint, effectively preventing vertical displacement of the door and window frame 1 due to gravity, wind loads, etc. The horizontal combination structure also restricts lateral swaying, forming a multi-dimensional constraint system. This greatly enhances the connection strength and stability between the door / window and the wall structure, ensuring the building maintains structural integrity under complex external forces. Regarding installation accuracy and reliability, the precise fit of the protrusions and recesses provides a clear positioning reference for the installation of the door and window frame 1. Construction workers can quickly and accurately align the installation based on the protrusion-recessed structure, reducing installation errors and improving assembly accuracy. Simultaneously, this structure forms a tight interlock after installation, avoiding loose connections due to installation deviations, reducing potential quality issues, ensuring one-time door and window installation, and improving overall construction quality.

[0037] From a durability perspective, the tight fit of the snap-fit ​​joints reduces the erosion of the connection points by external environmental factors, effectively preventing rainwater, moisture, dust, and other pollutants from entering the gaps. This prevents material aging and corrosion at the connection between the door / window frame and the wall structure due to long-term erosion, extending the service life of the doors / windows and the wall structure, reducing maintenance and replacement frequency, and saving on later operating costs. Furthermore, the seamless connection formed by this structure further enhances the sealing performance of the door / window area, resulting in superior performance in thermal insulation, sound insulation, and noise reduction. It continuously provides users with a comfortable and energy-efficient indoor environment, highlighting the exceptional value of innovative details in the design of building door / window structures.

[0038] Specifically, the second mounting component 6 is mounted on the door and window frame 1. The second mounting component 6 has a first mounting member 62, a second mounting member 63, and a third mounting member 64. The first mounting member 62 and the third mounting member 64 are fixed by the second mounting member 63. The first mounting member 62 and the second mounting member 63 are both connected to the door and window frame 1 in the horizontal direction. The second locking part 61 is disposed on the third mounting member 64, and the third mounting member 64 is engaged with the first mounting component 5.

[0039] In practical use, regarding structural stability, the first mounting component 62 and the second mounting component 63 are connected to the door and window frame 1 in the horizontal direction, forming a stable horizontal support system. This effectively disperses external forces such as wind loads and impact forces on the door and window in the horizontal direction, preventing lateral deformation of the door and window frame 1. The third mounting component 64 is engaged with the first mounting component 5 through the second locking part 61, providing reliable constraint in the vertical direction and preventing vertical displacement of the door and window frame 1. The synergistic effect in the horizontal and vertical directions makes the connection between the door / window and the wall structure more robust, significantly improving the overall structure's wind and earthquake resistance and ensuring building safety. In terms of installation convenience and flexibility, the combination of the three mounting components allows the second mounting component 6 to be disassembled and installed modularly. Construction personnel can flexibly adjust the installation sequence and method according to the size of the door and window frame 1 and the characteristics of the wall structure, reducing installation difficulty. Furthermore, if a mounting component is damaged, it is easy to replace or repair it without disassembling the entire component, reducing maintenance and time costs.

[0040] In terms of adaptability, this structural design is compatible with different types of door and window frames 1 and wall structures. By adjusting the size, shape, and connection method of the mounting components, it can meet diverse architectural design needs, enabling efficient and precise installation in both large commercial and residential buildings. Furthermore, the rational layout and tight connection of the second mounting component 6 reduces gaps between doors / windows and walls, enhances the sealing of the door / window area, and further improves the building's thermal insulation, sound insulation, and noise reduction effects, creating a more comfortable and energy-efficient indoor environment for users. This fully demonstrates the innovative breakthrough of this door and window structure in terms of functionality and practicality.

[0041] Specifically, the door and window frame 1 is provided with a support plate 13, the end of which is connected to the first mounting member 62 and the second mounting member 63; the first mounting member 62 and the second mounting member 63 are both provided with a fixing part 65, the two fixing parts 65 form a groove structure for inserting the support plate 13, and a sealing adhesive layer 66 is provided between the support plate 13 and the groove structure.

[0042] In practical use, at the structural reinforcement level, the addition of the supporting horizontal plate 13 provides additional lateral support for the door and window frame 1, forming a stable triangular force-bearing system with the first mounting component 62 and the second mounting component 63. This effectively disperses the load borne by the door and window, enhances the deformation resistance of the door and window frame 1, and prevents the frame from twisting or deforming due to external forces. Especially when dealing with extreme environments such as strong winds and earthquakes, it can significantly improve the stability and safety of the door and window structure. At the same time, the groove structure formed by the fixed connection part 65 fits tightly with the supporting horizontal plate 13, restricting the displacement of the supporting horizontal plate 13 and further enhancing the overall connection strength, making the connection between the door and window frame 1 and the second mounting component 6 more reliable.

[0043] From a sealing and energy-saving perspective, the sealant layer 66 fills the tiny gaps between the supporting horizontal plate 13 and the groove structure, effectively preventing the infiltration of rainwater, moisture, and dust. This avoids problems such as rust and rot caused by moisture affecting the door and window frame 1, extending the service life of the doors and windows. Furthermore, the sealant layer 66 significantly improves the airtightness of the door and window area, reduces indoor and outdoor air convection, lowers heat loss, enhances the building's thermal insulation performance, helps achieve building energy-saving goals, and reduces users' energy consumption costs. In terms of construction and maintenance, the groove structure provides precise positioning for the installation of the supporting horizontal plate 13, allowing construction personnel to complete the installation work quickly and accurately, improving construction efficiency. When doors and windows malfunction and require repair, the modular connection between the supporting horizontal plate 13 and the second installation component 6 facilitates disassembly and replacement, reducing maintenance difficulty. Moreover, the use of the sealant layer 66 does not hinder subsequent maintenance work; on the contrary, it allows for resealing after repairs, ensuring that the performance of the doors and windows remains unaffected. Overall, this design optimizes the door and window structure from multiple dimensions, including structure, sealing, and construction, improving building quality and user experience.

[0044] Specifically, the first mounting member 62 is provided with a third locking part 621, and the second mounting member 63 is provided with a fourth locking part 631 that engages with the third locking part 621; a rectangular structure is formed between the second mounting member 63 and the third mounting member 64, and an abutment structure 67 for abutting the two is provided at the corner of the rectangular structure.

[0045] In practical use, the engagement of the third locking part 621 and the fourth locking part 631 enhances the structural strength, allowing the first mounting part 62 and the second mounting part 63 to mesh tightly, effectively preventing relative displacement between them in the horizontal direction and enhancing the overall rigidity of the second mounting assembly 6. The rectangular structure formed by the second mounting part 63 and the third mounting part 64, together with the abutment structure 67 at the corner, connects the three into a stable mechanical system, like a reinforced frame. This system can better disperse and transmit the external forces on the doors and windows. Whether it is vertical load or lateral wind load, it can be evenly transmitted to the wall through this structure, reducing local stress concentration, significantly improving the load-bearing capacity and deformation resistance of the door and window structure, and ensuring the safety of the building for long-term use.

[0046] From the perspective of installation accuracy and convenience, the snap-fit ​​structure provides a clear installation reference, allowing construction personnel to quickly and accurately align and assemble the first mounting component 62 and the second mounting component 63, reducing installation errors. The design of the rectangular structure and the abutment structure 67 makes the installation of the second mounting component 63 and the third mounting component 64 more efficient, eliminating the need for complex positioning and adjustments, improving construction efficiency and reducing labor costs. Regarding structural stability and durability, the support at the rectangular corners of the abutment structure 67 further enhances the stability of the second mounting component 6, preventing loosening and deformation due to external forces. Simultaneously, the tight snap-fit ​​and abutment fit reduces the erosion of the connection points by external environmental factors, preventing rainwater and moisture from entering the connection gaps, preventing metal parts from rusting, extending the service life of the door and window structure, and reducing later maintenance costs. Furthermore, this structural design can improve the sealing of the door and window area by reducing gaps, enhancing the building's thermal insulation and sound insulation effects, creating a more comfortable and energy-efficient living and working environment for users, fully demonstrating the innovative and practical value of this door and window structure in its detailed design.

[0047] Specifically, the abutting structure 67 has a planar support portion 671 provided on the second mounting member 63 and / or the third mounting member 64, a T-shaped groove portion 672 provided on the third mounting member 64 and / or the second mounting member 63, and an abutting member 673 for abutting the two. The abutting member 673 has a planar elastic portion 674 that abuts against the planar support portion 671 and a T-shaped protrusion portion 675 that abuts against the T-shaped groove portion 672.

[0048] In practical use, to enhance structural stability, the planar elastic part 674 and the planar support part 671 are tightly abutted, and the T-shaped protrusion and the T-shaped groove are precisely fitted together, forming a multi-directional, multi-layered constraint system. When the doors and windows are subjected to external forces, this structure can effectively distribute the load, limit the relative displacement between the second mounting part 63 and the third mounting part 64, prevent deformation of the rectangular structure, and make the connection between the door and window frame 1 and the wall structure more stable. Whether dealing with the lateral thrust caused by strong winds or the impact of collisions in daily use, the abutment structure 67 can absorb and buffer external forces through a combination of elasticity and rigidity, improving the overall deformation resistance and load-bearing capacity of the doors and windows, and ensuring building safety.

[0049] From the perspective of ease of installation and flexibility, this modular abutment structure 67 facilitates rapid assembly by construction personnel. The flat support part 671 and the T-shaped groove part provide a clear positioning benchmark for the installation of the abutment part 673, allowing installation to be completed without complicated tools, effectively improving construction efficiency. Furthermore, the elasticity of the abutment part 673 allows it to adapt to a certain range of dimensional errors, reducing the stringent requirements for installation accuracy. It can achieve good fit in door and window frames 1 and wall structures of different specifications, enhancing the versatility of the design. In terms of durability and sealing, the elastic design of the abutment part 673 ensures that it maintains a tight abutment state during long-term use, preventing loosening due to factors such as vibration and temperature changes. It effectively prevents external rainwater, moisture, and dust from seeping in through the connection points, reducing the risk of corrosion to the door and window frames 1 and installation components, and extending service life. At the same time, the tight abutment significantly improves the sealing of the door and window area, further enhancing the building's thermal insulation and sound insulation effects, reducing energy consumption, and creating a more comfortable and quiet indoor environment for users. Furthermore, the abutment structure 67 facilitates the disassembly and replacement of the abutment part 673 during later maintenance, resulting in low maintenance costs and fully demonstrating the balance and innovation of the design in terms of functionality, practicality, and economy.

[0050] Specifically, the fixing part 65 is provided with a plurality of linearly arranged inverted teeth 651, and the sealing adhesive layer 66 is fixed to the plurality of inverted teeth 651.

[0051] In practical use, the presence of the inverted teeth 651 significantly increases the contact area between the fixed part 65 and the sealant layer 66, creating an effect similar to "mortise and tenon joint." When the supporting horizontal plate 13 is subjected to external force, the inverted teeth 651 effectively prevent relative sliding between the sealant layer 66 and the fixed part 65, firmly fixing the sealant layer 66 to the fixed part 65, thereby enhancing the connection strength between the supporting horizontal plate 13 and the first and second mounting parts 63. This structure can better distribute and transfer the load borne by the doors and windows. Whether it is vertical gravity or lateral wind load, it can be stably transmitted to the door and window frame 1 and the wall structure through the synergistic effect of the inverted teeth 651 and the sealant layer 66, reducing local stress concentration, improving the overall stability and safety of the door and window structure, and effectively resisting the impact of the external environment on the doors and windows.

[0052] In terms of sealing performance optimization, the tight bond between the inverted teeth 651 and the sealant layer 66 further fills the tiny gaps between the supporting cross plate 13 and the fixed joint 65. The linearly arranged inverted teeth 651 act as multiple lines of defense, preventing rainwater, moisture, dust, and other external substances from seeping into the doors and windows, preventing the door and window frames 1 from rusting and rotting due to moisture, and extending the service life of the doors and windows. Simultaneously, this sealing structure effectively reduces indoor and outdoor air convection, reduces heat transfer, significantly enhances the building's thermal insulation performance, reduces energy consumption of air conditioning, heating, and other equipment, and achieves building energy conservation goals. From a construction and maintenance perspective, the design of the inverted teeth 651 provides clear adhesion points for the application and fixation of the sealant layer 66, allowing construction personnel to more easily apply the sealant layer 66 and improve construction efficiency. During later maintenance, if the sealant layer 66 ages or becomes damaged, the presence of the inverted teeth 651 facilitates precise location of the damaged area and allows for replacement without extensive disassembly, reducing maintenance difficulty and cost. In addition, the inverted tooth 651 structure is highly versatile and can be adapted to different types of sealant materials and window and door frames of specification 1. It can play a good role in a variety of building scenarios, fully demonstrating the comprehensive consideration of function, quality and cost in the details of the design.

[0053] Specifically, the door and window frame 1 is provided with a fixed window 14 at the top and two movable windows 15 symmetrically arranged at the bottom, and the movable windows 15 are hinged to the door and window frame 1.

[0054] In practical use, regarding flexibility, the two symmetrically arranged movable windows 15 at the bottom can be opened or closed independently, allowing users to freely adjust the ventilation area according to their actual needs. Compared to a single movable window, this provides more precise ventilation control. The fixed window 14 at the top provides stable lighting and structural support. The combination of the two functions balances ventilation and lighting, meeting diverse usage scenarios. In terms of structural stability, the fixed window 14 is located at the top of the door and window frame 1, reducing wear and tear on the upper structure caused by frequent opening and closing, and helping to maintain the overall stability of the door and window frame. The movable windows 15 at the bottom are connected by hinges, which distributes the force evenly and effectively disperses the force generated when the window is opened and closed to the door and window frame 1, reducing the risk of frame deformation due to stress concentration and ensuring the long-term reliability of the door and window.

[0055] In terms of safety and sealing, the hinged structure allows the movable window 15 to fit tightly against the window frame 1 when closed. Combined with sealing strips and other sealing designs, it effectively prevents wind, rain, and dust from entering the room. The fixed window 14, which does not require frequent opening and closing, is easier to ensure sealing. Together, they improve the airtightness and watertightness of the doors and windows. In addition, this design is also quite advantageous in terms of cleaning and maintenance. The movable window 15 can open inward or outward, making it easy for users to clean the inner and outer glass surfaces. The fixed window 14 has a larger area, reducing the gaps between the window sashes, making it easy to wipe and reducing the difficulty of cleaning and maintenance costs. The overall design takes into account functionality, safety, and practicality.
