Description
Technical Field
[0001] This utility model relates to the field of door and window technology, specifically to a door and window subframe structure and a door and window, and more particularly to an energy-saving door and window subframe structure. Background Technology
[0002] A window / door subframe is an auxiliary frame structure installed between the window / door opening and the main window / door frame. It is typically made of metal (such as steel or aluminum alloy), wood, or plastic and is pre-installed in the window / door opening. It provides a reference and facilitates the subsequent installation of the main window / door frame, serving functions such as sizing and positioning, protecting the window / door, facilitating installation, and enhancing window / door performance. It effectively improves the accuracy and quality of window / door installation, enhances the overall usability and durability of the windows / doors, and allows for better integration between the windows / doors and the building walls, enabling them to fulfill their intended functions.
[0003] Existing subframe structures typically consist of an outer subframe and an inner subframe. In use, these subframes are directly embedded in the wall and connected directly through the wall, creating a direct thermal bridge between them. In winter, when outdoor temperatures are low, heat is rapidly conducted through the outer subframe to the inner subframe, resulting in significant heat loss from the interior and increased heating energy consumption. In summer, outdoor heat easily enters the interior, increasing the cooling load and reducing the energy efficiency of the air conditioning system, which is detrimental to building energy conservation.

[0038] Compared with the prior art, the present invention has the following beneficial effects:
[0039] 1. This utility model adds a heat insulation strip between the outer and inner subframe structures of the door and window to block the heat conduction path between the outer and inner subframe structures, avoids the formation of a direct thermal bridge between the outer and inner subframe structures, reduces heat exchange between the interior and exterior, and thus ensures the comprehensive performance of ultra-low energy consumption doors and windows.

The multi-cavity thermal insulation strip has multiple independent cavities inside, which can effectively prevent heat from being conducted through the subframe. Air is difficult to form convection in these cavities. Heat transfer mainly takes place through the thermal conduction of air molecules. Since air has a low thermal conductivity, the efficiency of heat transfer is greatly reduced, achieving effective thermal insulation between indoors and outdoors, maintaining a relatively stable indoor temperature, and reducing energy consumption.
[0041] 3. The hook on the thermal insulation strip of this utility model is embedded in the wall, which is equivalent to adding an extra anchor point between the subframe and the wall. This anchoring effect can effectively prevent the subframe from loosening or shifting during long-term use, making the connection between the subframe and the wall more solid and enhancing the stability of the entire building structure.

[0077] This embodiment also provides a door and window, including the aforementioned door and window subframe structure.
[0078] Example 2:
[0079] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.
[0080] like Figures 1 to 6As shown, this embodiment provides a door and window enhanced energy-saving subframe structure. Its structural design features include modular installation of doors and windows. The installation of doors and windows is usually divided into two main parts: the enhanced energy-saving subframe and the whole window unit.
[0081] The enhanced energy-saving subframe for doors and windows, serving as the base for connecting doors and windows to the wall, must not only meet the load-bearing and displacement requirements of standardized safety structures for building doors and windows, but also meet the energy-saving requirements of doors and windows, especially for ultra-low energy consumption buildings. Since the doors and windows are pre-assembled in the factory with glass, hardware, and other components, they can be quickly installed on-site via a plug-in method, reducing on-site procedures and construction errors. The installation interface design uses a matching plug-in connection, and the movable design can absorb deformation between the enhanced energy-saving subframe and the outer frame of the door and window, enhancing overall stability. Adjustments to the sliding and adapter components accommodate opening size errors during installation, filling gaps to reduce air infiltration and heat loss, and ensuring the overall energy-saving performance of the enhanced energy-saving subframe, the outer frame of the door and window, and the wall.
[0082] In this embodiment, the corner reinforcement and sealing enhancement of the energy-saving subframe's corners utilizes reinforced profiles and screw connections to ensure a robust and reliable structure while preventing water leakage. The reinforced energy-saving subframe structure design incorporates a multi-cavity thermal insulation strip between the inner and outer sides of the subframe, blocking heat conduction paths, reducing the risk of cold bridging, and ensuring the comprehensive performance of ultra-low energy consumption windows and doors, including energy efficiency and safety.
[0083] The connection between the enhanced energy-saving subframes for doors and windows and the civil engineering wall structure is divided into two types: pre-installed PC structure and post-installed non-PC structure. In the pre-installed PC structure method, concrete aggregate is poured during wall construction, firmly fixing the enhanced energy-saving subframes to the PC wall structure 13. In the post-installed non-PC method, concrete mortar or high-pressure injection of anti-leakage mortar is poured during wall construction, firmly fixing the enhanced energy-saving subframes to the civil engineering wall structure 7. This provides a structural and technical foundation for meeting various high-performance requirements for near-zero energy building door and window installations, including structural safety, modular assembly, leak-proof performance, thermal insulation, fire resistance, energy efficiency, aesthetics, and secondary replacement. This process empowers the improvement of ultra-low energy building door and window technology. The exterior of the wall is equipped with a building insulation and waterproof layer 8, a building decorative surface 9, and an interior plaster layer 10.
[0084] like Figure 3 and Figure 4 As shown, considering the enhanced energy-saving subframes for doors and windows and the characteristics of door and window installation and design, the working principle of its connection structure is as follows:
[0085] This embodiment provides a reinforced energy-saving subframe structure for doors and windows, relating to an installation structure for such reinforced energy-saving subframes for doors and windows, such as... Figure 4As shown, considering energy-saving requirements and the characteristics of rapid installation, high energy efficiency, and robust structure of doors and windows, the working principle of its connection structure with the wall is as follows:
[0086] The unitized energy-saving doors and windows have an enhanced energy-saving subframe installed on one side of the lower sill or the left and right sides. The inner and outer cavities are connected by an enhanced energy-saving subframe thermal insulation strip (i.e., a thermal insulation strip 5 is installed between the outer subframe 4 and the inner subframe 6). The enhanced energy-saving thermal insulation strip has a multi-cavity structure with high thermal insulation and conductivity (i.e., the thermal insulation cavity 502 of the subframe) to effectively block the heat conduction path, reduce the risk of cold bridge, and ensure its high energy efficiency. It also features an enhanced energy-saving thermal insulation strip hook (i.e., the inlet frame thermal insulation strip hook 501). This hook, located at the contact point between the enhanced energy-saving subframe and the wall, effectively transfers the force from the outer frame of the door / window to the enhanced energy-saving subframe, and then from the subframe to the wall, creating a seamless integration between the door / window and the wall. This unique high-rigidity connection structure for enhanced energy-saving subframes ensures the safety performance of ultra-low energy consumption doors and windows. The materials used must meet the energy-saving and structural safety requirements of ultra-low energy consumption buildings. The main materials of the enhanced energy-saving subframe thermal insulation strip are primarily polyamide 66, rigid polyurethane foam, and graphite polystyrene, which have low thermal conductivity, significantly reducing thermal bridging effects and providing high structural strength and insulation properties. Figure 4 In the middle section, a high-precision mechanical connection is required between the inner and outer cavities of the reinforced energy-saving subframe. Suitable for pre-embedded installation, such as... Figure 4 As shown, high-strength metal materials and durable, energy-saving subframe material polyamide 66 are used, which have high compressive strength and nail-holding power to support the heavy doors and windows and ensure the comprehensive performance requirements of ultra-low energy consumption doors and windows.
[0087] The unitized energy-saving door and window reinforced energy-saving subframe is provided on one side of the upper part or left and right sides. The reinforced energy-saving subframe thermal insulation strip is provided between the inner and outer cavities and the inner and outer sides of the reinforced energy-saving subframe (i.e., the hook subframe thermal insulation strip 2 is provided between the outer hook subframe 1 and the inner hook subframe 3). The reinforced energy-saving thermal insulation strip is provided with a multi-cavity structure with high thermal insulation and conductivity (i.e., hook subframe thermal insulation cavity 202) to effectively block the heat conduction path, reduce the risk of cold bridge, and ensure its high energy efficiency. It also features an enhanced energy-saving thermal insulation strip hook (i.e., hook-and-frame thermal insulation strip hook 201). This hook, located at the contact point between the enhanced energy-saving subframe and the wall, effectively transfers the force from the outer frame of the door / window to the enhanced energy-saving subframe, and then from the subframe to the wall, creating a seamless integration between the door / window and the wall. This unique high-rigidity connection structure for enhanced energy-saving subframes ensures the safety performance of ultra-low energy consumption doors and windows. The materials used must meet the energy-saving and structural safety requirements of ultra-low energy consumption buildings. The main materials of the enhanced energy-saving subframe thermal insulation strip are primarily polyamide 66, rigid polyurethane foam, and graphite polystyrene, which have low thermal conductivity, significantly reducing thermal bridging effects and providing high structural strength and insulation properties. Figure 3 In this design, a high-precision mechanical connection is required between the inner and outer cavities of the reinforced energy-saving subframe and the main body of the reinforced energy-saving subframe thermal insulation strip. Suitable for pre-embedded installation, such as... Figure 3 As shown, high-strength metal materials and durable, energy-saving subframe material polyamide 66 are used, which have high compressive strength and nail-holding power to ensure the comprehensive performance requirements of ultra-low energy consumption doors and windows.
[0088] The principle of connection of enhanced energy-saving subframes for doors and windows:
[0089] like Figure 3 As shown, considering the characteristics of reinforced energy-saving subframes for doors and windows and their installation and design, the working principle of the reinforced energy-saving subframe connection structure is as follows: a slotted reinforced energy-saving subframe is installed on the upper part or one side of the left and right sides of the unitized energy-saving door and window reinforced energy-saving subframe. Figure 3 In the middle, the inner and outer cavities of the enhanced energy-saving subframe are provided with unit-type hooks and enhanced energy-saving subframe assembly screw holes (i.e., the first outer assembly hole 103 and the first inner assembly hole 303), two such as Figure 3 The enhanced energy-saving subframe structure of the doors and windows is combined into an L-shaped enhanced energy-saving subframe structure on the top or one of the left and right sides.
[0090] like Figure 4 As shown, combining the characteristics of reinforced energy-saving subframes for doors and windows and their installation and design, the working principle of the reinforced energy-saving subframes and the connection structure between doors / windows and walls is as follows: A grooved reinforced energy-saving subframe is installed at the bottom or on one of the left or right sides of the unitized energy-saving door / window reinforced energy-saving subframe. Figure 4In the middle, the inner and outer cavities of the enhanced energy-saving subframe are equipped with unit-type hooks and enhanced energy-saving subframe assembly screw holes (i.e., the second outer assembly hole 403 and the second inner assembly hole 603), two such as Figure 4 The door and window reinforced energy-saving subframes are combined to form an L-shaped reinforced energy-saving subframe structure on the lower part or the left and right sides, with one side being an L-shaped reinforced energy-saving subframe structure.
[0091] Figure 3 The L-shaped reinforced energy-saving subframe structure in the slot and another L-shaped reinforced energy-saving subframe structure in the slot are assembled with screws in the unit hook reinforced energy-saving subframe assembly screw hole positions in the inner and outer cavity parts, thereby forming a complete rectangular door and window reinforced energy-saving subframe product.
[0092] 7. Connection principle between the enhanced energy-saving subframe of doors and windows and the civil engineering wall structure:
[0093] The connection between the enhanced energy-saving subframes for doors and windows and the civil engineering wall structure is divided into two types: front-mounted enhanced energy-saving subframes (dry and wet construction methods) and rear-mounted enhanced energy-saving subframes (dry and wet construction methods). Figure 3 , Figure 4 , Figure 5 , Figure 6 .
[0094] In dry construction, pressure strips and subframe moldings are used to connect the subframe structure and the outer frame of doors and windows. In wet construction, sealant is used to connect the subframe structure and the outer frame of doors and windows.
[0095] The pre-installation method is a PC structure. The reinforced energy-saving subframe is installed in the groove of the door and window sill or one of the left and right sides, with inner and outer pressure line cavities (i.e., the second outer cavity 402 and the second inner cavity 602) and subframe pressure strip 11. It is a combination structure of the inner and outer sides of the adapter for matching unitized door and window frames (this is the dry construction method of reinforced energy-saving subframe); the reinforced energy-saving subframe is installed in the groove of the door and window sill or one of the left and right sides, with sealant 13. It is a combination structure of the inner and outer sides of the adapter for matching unitized door and window frames (this is the wet construction method of reinforced energy-saving subframe).
[0096] The unit-type hook-reinforced energy-saving subframe with open cavity hooks (i.e., the first outer hook 104 and the first inner hook 304) on both sides is designed for a high-strength structural connection between the hook-reinforced energy-saving subframe and the civil engineering wall structure. Figure 3The material of the C-shaped cavity in contact with the cement must be compatible with the cement material. The upper part or one of the left and right sides of the door / window has a unitized slotted reinforced energy-saving subframe with inner and outer cavities (i.e., the first outer open cavity 101 and the first inner open cavity 301), which is a combination structure of the inner and outer sides of the adapter for matching the unitized door / window frame.
[0097] The unit-type inlet-groove reinforced energy-saving subframe with open cavity hooks (i.e., the second outer hook 404 and the second inner hook 604) are provided on both sides for high-strength structural connection between the inlet-groove reinforced energy-saving subframe and the civil engineering wall structure 7. Figure 4 The enhanced energy-saving subframe in the design requires that the material of the C-shaped cavity in contact with the cement be in sync with the cement material. Using a pre-installed PC structure, the enhanced energy-saving subframe for doors and windows is fixed in the concrete wall mold cast in the PC structure factory according to the building design and construction requirements after leaving the door and window factory. Because the outer cavities of the enhanced energy-saving subframe are open-type C-shaped structures, when the concrete aggregate is poured into the PC structure wall mold, it simultaneously fills and compacts the C-shaped grooves in the outer cavities of the enhanced energy-saving subframe.
[0098] The post-installation method is a non-PC structure. After leaving the window and door factory, the enhanced energy-saving subframe is fixed in the non-PC structure wall according to the traditional installation method based on building design and construction requirements. The enhanced energy-saving subframe is inserted into the groove on one of the two sides of the window or door sill. The inner and outer sides of the unitized window and door frame are sealed with sealant 13 (this is the wet construction method for the enhanced energy-saving subframe). Because the outer cavities of the enhanced energy-saving subframe are open C-shaped structures, when the non-PC structure wall is constructed, the C-shaped grooves in the outer cavities of the enhanced energy-saving subframe will be filled and compacted when concrete mortar or high-pressure anti-seepage mortar is poured in the cavity. This firmly fixes the enhanced energy-saving subframe in the civil wall, providing structural requirements for meeting various performance requirements such as structural safety, unitized modularity, anti-seepage, thermal insulation, fire resistance, energy saving, aesthetics, and secondary replacement for ultra-low energy consumption building window and door installation.
[0099] The principle of connecting the enhanced energy-saving subframe of doors and windows with the door and window assembly:
[0100] Figure 5 The L-shaped enhanced energy-saving subframe structure in the groove and another Figure 4 A rectangular door / window reinforced energy-saving subframe is formed by combining an L-shaped reinforced energy-saving subframe structure with a slotted frame. This subframe is positioned either in front of or behind the opening in the building wall. When connecting the finished door / window to the reinforced energy-saving subframe, a specially designed structural adapter is used around the perimeter of the door / window frame.
