Description

Technical Field

[0001] This utility model relates to the technical field of building component installation structures, and more specifically, to a window frame installation component. Background Technology

[0002] In the field of building construction, doors and windows are key components that interact between the building structure and the external environment. Their installation quality directly affects the building's sealing, stability, and overall performance. The installation structure design of the window frame is one of the core factors that determines the installation quality of doors and windows. Currently, the mainstream installation method for building window frames is to directly fit the main frame into the pre-designed window opening in the main structure (such as a wall). Specifically, during construction, the window opening size must first be measured on-site, and then the main frame is cut and adjusted according to the measurement results to ensure the fit between the main frame and the window opening. Subsequently, the main frame is fixed in the window opening by drilling holes in the inner wall of the window opening in the main structure and inserting fasteners (such as expansion bolts). Finally, the gap between the main frame and the window opening is filled and sealed. However, the aforementioned traditional installation methods have significant drawbacks: Firstly, assembly efficiency is low. Since the main frame needs to be cut and adjusted on-site according to the window opening dimensions, it requires high precision from construction workers, and the adjustment process is time-consuming. Simultaneously, fixing the main frame to the main structure requires drilling and installing fasteners point by point, a cumbersome process. Especially in large-area building window and door installation scenarios, this can easily lead to extended construction periods, making it difficult to meet the demands of efficient construction. Secondly, the risk of water seepage due to structural damage is high. Drilling numerous holes in the inner wall of the window opening in the main structure to fix the main frame will damage the integrity of the main structure, resulting in impaired waterproofing performance at the window opening. Furthermore, the sealing effect of the gaps between the main frame and the window opening is easily affected by the construction process. If the seal is incomplete, rainwater can easily seep into the building through the drilled gaps or cracks, potentially causing mold growth and structural corrosion after long-term use, severely impacting the building's durability and living comfort. With the construction industry's increasing demands for construction efficiency, building quality, and durability, traditional window frame installation methods are no longer sufficient to meet actual needs. There is an urgent need for a window frame installation structure solution that can improve assembly efficiency and reduce structural damage and water seepage risks. Utility Model Content

[0003] The purpose of this utility model is to provide a window frame installation component to solve the technical problems of low efficiency in installing window frames, high damage to the main structure, and high risk of water seepage in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: Firstly, a window frame mounting assembly is provided, comprising: A sub-frame, a main frame mounted on the sub-frame, and a connector connecting the sub-frame and the main frame; The sub-frame is used for installation in the window opening of the main structure. The sub-frame includes a sub-frame frame and a plurality of connecting structures arranged sequentially along the circumference of the sub-frame frame.

[0008] In one embodiment, the length directions of the first connecting hole, the second connecting hole, and the length direction of the connector are perpendicular to each other, so that the connector connecting the main frame and the sub-frame can move along the length directions of the first connecting hole and the second connecting hole.

Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating relative importance or the number of technical features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. The specific implementation of this utility model is described in more detail below with reference to specific embodiments: like Figures 1 to 3 As shown, an embodiment of this utility model provides a window frame mounting assembly 100, comprising: Sub-frame 1, main frame 2 installed in sub-frame 1, and connector 3 connecting sub-frame 1 and main frame 2; The sub-frame 1 is used to install in the window opening of the main structure. The sub-frame 1 includes a sub-frame 11 and a plurality of connecting structures 12 arranged sequentially along the circumference of the sub-frame 11. The interior of the sub-frame 11 forms a main frame installation space 10 for installing the main frame 2. The connecting structures 12 are located on the outer peripheral wall of the sub-frame 11 and are used to connect with the main structure.

[0025] The window frame mounting assembly 100 consists of a sub-frame 1, a main frame 2, and a connector 3. The sub-frame 1 is composed of a sub-frame 11 and a plurality of connecting structures 12 arranged sequentially along the circumference of the sub-frame 11. The sub-frame 11 forms a main frame mounting space 10 for mounting the main frame 2. The connecting structures 12 are arranged on the outer peripheral wall of the sub-frame 11. The connector 3 is used to connect the sub-frame 1 and the main frame 2. The main frame 2 is installed in the main frame mounting space 10 of the sub-frame 1, and the sub-frame 1 is used to be installed in the window opening of the main structure.

[0026] Its working principle is to first connect and fix the sub-frame 1 to the window opening of the main structure through the connecting structure 12 on the outer peripheral wall, so that the sub-frame 1 is stably assembled in the window opening. Then, the main frame 2 is placed in the main frame installation space 10 inside the sub-frame 11. Then, the sub-frame 1 and the main frame 2 are connected and fastened through the connector 3, thereby completing the assembly of the entire window frame installation assembly 100 in the window opening of the main structure.

[0027] The technical advantages of this solution are that the sub-frame 1 can be pre-processed according to the standardized dimensions of the window openings in the main structure, eliminating the need for repeated cutting and adjustment of the main frame 2 on-site. Simultaneously, the sub-frame 1 is connected to the main structure via the connecting structure 12 on its outer perimeter wall, eliminating the need for extensive drilling into the inner walls of the window openings in the main structure. The connection between the sub-frame 1 and the main frame 2, facilitated by the connector 3, simplifies the installation process, reduces the precision requirements for construction workers, significantly improves the efficiency of window frame assembly, and shortens the construction cycle, making it particularly suitable for large-area building door and window installation scenarios. Furthermore, it reduces damage to the integrity of the main structure, lowering the risk of water seepage due to structural damage. The main frame 2 and sub-frame 1 are also fitted together via the pre-set main frame installation space 10 and the connector 3, reducing the problem of unstable installation gaps and further improving the sealing performance of the doors and windows after installation. This prevents problems such as wall mold and structural corrosion caused by rainwater seepage, ensuring the durability of the building and the comfort of living.

[0028] Please refer to the following: Figure 4 In one embodiment, the subframe 11 is provided with a plurality of first connecting holes 111 along its circumference. The first connecting holes 111 are elongated holes, and the connector 3 is detachably connected to the first connecting holes 111.

[0029] In terms of the structural composition of the window frame mounting assembly 100, the sub-frame 11 has multiple first connecting holes 111 arranged around its circumference, and the first connecting holes 111 are elongated holes. At the same time, the connector 3 forms a detachable connection with the first connecting holes 111. This structural design, together with the original connecting structure 12 in the sub-frame 1, the main frame 2 and the connector 3, constitutes a complete window frame mounting assembly 100 system.

[0030] Its working principle is that after the sub-frame 1 is fixed to the window opening of the main structure through the outer peripheral wall connection structure 12 and the main frame 2 is placed into the main frame installation space 10 of the sub-frame 11, the connector 3 is correspondingly connected to the elongated first connection hole 111 in the circumferential direction of the sub-frame 11. Through the structural characteristics of the elongated hole, the installation position of the connector 3 can be finely adjusted to ensure that the connector 3 can be accurately connected and fixed with the main frame 2, so as to achieve stable assembly of the sub-frame 1 and the main frame 2. Since the connector 3 and the first connection hole 111 are detachable, if the main frame 2 or the sub-frame 1 needs to be maintained or replaced in the future, the connector 3 can be easily disassembled to separate the sub-frame 1 and the main frame 2.

[0031] The technical effect lies in the fact that multiple elongated first connecting holes 111 are arranged circumferentially along the sub-frame 11. On the one hand, it can adapt to the installation requirements of main frames 2 of different sizes. By fine-tuning the position of the elongated holes, it avoids connection difficulties caused by slight deviations in the size of the main frame 2 or installation misalignment errors, improving installation adaptability and ease of operation, and further shortening the installation time. Combined with the pre-standardized processing of the sub-frame 1 in the previous scheme, it can significantly improve the efficiency of window frame assembly. On the other hand, the detachable connection design facilitates the maintenance, repair or replacement of window frame components in the later stage without damaging the sub-frame 1 or the main structure, reducing secondary damage to the building structure during maintenance. At the same time, the elongated hole structure can provide a certain displacement buffer space for the connector 3 when the window frame components are slightly deformed due to environmental factors such as temperature changes, reducing the impact of component deformation on connection stability, indirectly reducing the risk of water seepage due to loose connections, ensuring the sealing and stability of the window frame for long-term use, and forming a synergistic effect with the goal of reducing structural damage and improving efficiency in the overall window frame installation component 100 scheme.

[0032] Please refer to the following: Figure 5 In one embodiment, the main frame 2 is provided with a second connecting hole 201 corresponding to the first connecting hole 111. The second connecting hole 201 is an elongated hole. The connector 3 is sequentially inserted into the first connecting hole 111 and the second connecting hole 201. The two ends of the connector 3 are used to lock the sub-frame 11 and the main frame 2, respectively.

[0033] In terms of the structural composition of the window frame mounting assembly 100, the main frame 2 has a second connecting hole 201 corresponding to the first connecting hole 111 of the sub-frame 11, and the second connecting hole 201 is an elongated hole. The connector 3 can be sequentially inserted into the first connecting hole 111 and the second connecting hole 201. At the same time, the two ends of the connector 3 are used to lock the sub-frame 11 and the main frame 2 respectively. This structure, together with the first connecting hole 111 of the sub-frame 11, the overall structure of the sub-frame 1, and the main frame 2, constitutes a more complete window frame mounting connection system.

[0034] Its working principle is that after the sub-frame 1 is fixed to the window opening of the main structure through the outer peripheral wall connection structure 12 and the main frame 2 is placed in the main frame installation space 10 inside the sub-frame 11, the second connection hole 201 of the main frame 2 is aligned with the first connection hole 111 of the sub-frame 11. Then, the connector 3 is passed through the aligned first connection hole 111 and second connection hole 201 in sequence. Finally, the sub-frame 11 and the main frame 2 are locked by operating the two ends of the connector 3 respectively, so that the sub-frame 1 and the main frame 2 form a stable connection and the assembly of the window frame assembly is completed.

[0035] Its technical advantage lies in the fact that both the second connecting hole 201 of the main frame 2 and the first connecting hole 111 of the sub-frame 11 are elongated holes. Their cooperation allows for bidirectional fine-tuning of the installation position of the connector 3, effectively addressing minor dimensional deviations during the processing of the main frame 2 or the installation of the sub-frame 1, as well as errors in the alignment of the main frame 2 and the sub-frame 1. This avoids installation difficulties caused by misaligned holes, significantly improving installation adaptability and ease of operation, further shortening installation time. Combined with the pre-standardized processing of the sub-frame 1, it can more efficiently meet the installation needs of large-area building doors and windows. Furthermore, the design of locking the sub-frame 11 and the main frame 2 at both ends of the connector 3 can increase... The connection between the sub-frame 1 and the main frame 2 is strengthened to improve stability and reduce gaps caused by loose connections. This reduces the risk of rainwater seeping in through these gaps. Furthermore, the elongated hole structure provides a certain displacement buffer space for the connector 3 when the window frame components are slightly deformed due to environmental factors such as temperature changes. This prevents damage to the connection structure 12 caused by component deformation and ensures the long-term sealing and structural stability of the window frame. In addition, this connection method retains the detachable feature. When maintaining or replacing the main frame 2 or the sub-frame 1, it is only necessary to loosen both ends of the connector 3 to separate the two without damaging the main structure or window frame components, thus reducing maintenance costs and secondary impacts on the building.

[0036] In one embodiment, the length direction X of the first connecting hole 111, the length direction Y of the second connecting hole 201, and the length direction of the connector 3 are perpendicular to each other, so that the connector 3 connecting the main frame 2 and the sub-frame 11 can move along the length direction X of the first connecting hole 111 and the length direction Y of the second connecting hole 201.

[0037] In terms of the structural composition of the window frame mounting assembly 100, the X-direction of the hole length of the first connecting hole 111 on the sub-frame 11, the Y-direction of the hole length of the second connecting hole 201 on the main frame 2, and the length direction of the connector 3 are all perpendicular to each other. The first connecting hole 111 is arranged around the sub-frame 11, and the second connecting hole 201 is arranged on the main frame 2 corresponding to the first connecting hole 111. The connector 3 can be sequentially inserted through the first connecting hole 111 and the second connecting hole 201 and locked between the sub-frame 11 and the main frame 2 at both ends. This structure further improves the connection system between the sub-frame 1 and the main frame 2.

[0038] Its working principle is as follows: after the sub-frame 1 is fixed to the window opening of the main structure and the main frame 2 is placed into the main frame installation space 10 of the sub-frame 11, the second connecting hole 201 of the main frame 2 is aligned with the first connecting hole 111 of the sub-frame 11. Then, the connector 3 is inserted into the two holes. Since the three are perpendicular to each other, the connector 3 can move freely along the length direction X of the first connecting hole 111 and the length direction Y of the second connecting hole 201. By adjusting the position of the connector 3 in the two holes through this bidirectional movement, until a suitable locking position is found, the two ends of the connector 3 are locked to the sub-frame 11 and the main frame 2 respectively, so as to achieve a stable connection between the two.

[0039] Its technical advantage lies in the fact that the bidirectional perpendicular design gives the connector 3 bidirectional movement and adjustment capability. On the one hand, it can better accommodate the processing errors of the main frame 2, the installation deviation of the sub-frame 1, and the alignment deviation between the main frame 2 and the sub-frame 1. Even with multi-directional dimensional deviations, the connector 3 can quickly find a suitable connection position, avoiding installation jams caused by insufficient hole precision. This significantly improves the convenience and adaptability of the installation operation, further shortening the installation time. Combined with the standardized processing characteristics of the sub-frame 1, the efficiency improvement is even more significant in large-area door and window installation scenarios. On the other hand, the bidirectional movement space can adjust the temperature... When changes, building settlement, and other factors cause slight deformation of window frame components in multiple directions, the connector 3 provides sufficient displacement buffer to avoid stress concentration that could damage the connection structure 12, ensuring connection stability. At the same time, it reduces gaps caused by component deformation, lowering the risk of rainwater infiltration. Furthermore, the detachable nature of the connector 3 is retained, allowing for adjustment or disassembly simply by loosening both ends during later maintenance or replacement, without damaging the window frame components or the main structure. This reduces maintenance costs and secondary damage, perfectly aligning with the design goals of the overall window frame installation assembly 100: improving assembly efficiency and reducing structural damage and water seepage risks.

[0040] In one embodiment, the length direction X of the first connecting hole 111 is perpendicular to the circumferential direction of the sub-frame 11, and the length direction Y of the second connecting hole 201 is parallel to the circumferential direction of the sub-frame 11.

[0041] In terms of the structural composition of the window frame mounting component 100, the sub-frame 11 has multiple first connecting holes 111 arranged circumferentially with their length direction perpendicular to the circumferential direction of the sub-frame 11. The main frame 2 has second connecting holes 201 arranged corresponding to the first connecting holes 111 with their length direction parallel to the circumferential direction of the sub-frame 11. Both the first connecting holes 111 and the second connecting holes 201 are elongated holes. The connector 3 can be sequentially inserted into the first connecting holes 111 and the second connecting holes 201 and locked at both ends to the sub-frame 11 and the main frame 2 respectively. This structure, together with the overall frame of the sub-frame 1 and the main frame 2, constitutes a precisely fitted connection system.

[0042] Its working principle is that after the sub-frame 1 is fixed to the window opening of the main structure through the outer peripheral wall connection structure 12 and the main frame 2 is placed in the main frame installation space 10 inside the sub-frame 11, the second connecting hole 201 of the main frame 2 is aligned with the first connecting hole 111 of the sub-frame 11. At this time, since the length direction of the first connecting hole 111 is perpendicular to the circumference of the sub-frame 11 and the length direction of the second connecting hole 201 is parallel to the circumference of the sub-frame 11, the connector 3 inserted into the two holes can be adjusted in both directions along the direction perpendicular to the circumference of the sub-frame 11 (based on the first connecting hole 111) and the direction parallel to the circumference of the sub-frame 11 (based on the second connecting hole 201). After adjusting to the appropriate locking position, the two ends of the connector 3 are locked to the sub-frame 11 and the main frame 2 respectively to achieve a stable connection between the two.

[0043] The technical advantage lies in the fact that the hole lengths of the first connecting hole 111 and the second connecting hole 201 in different directions (parallel and perpendicular to the circumference of the sub-frame 11) can be specifically adapted to errors in different dimensions during the assembly of the main frame 2 and the sub-frame 1. The adjustment of the first connecting hole 111 perpendicular to the circumference can compensate for the dimensional deviation of the main frame 2 along the circumference of the sub-frame 11, and the adjustment of the second connecting hole 201 parallel to the circumference can correct the radial alignment deviation between the main frame 2 and the sub-frame 11. This significantly improves the flexibility of installation and adaptation, avoids installation difficulties caused by insufficient adjustment in a single direction, and further shortens the installation operation time. This is further enhanced by the pre-standardized processing characteristics of the sub-frame 1. In large-scale building window and door installation scenarios, it can improve assembly efficiency. At the same time, the elongated hole structure in different directions can provide displacement buffer space for the connector 3 when the window frame components deform in the circumferential or radial direction due to factors such as temperature changes and slight building settlement. This avoids deformation stress from damaging the connection structure 12, ensures connection stability, reduces gaps caused by component deformation, and reduces the risk of rainwater infiltration. In addition, the connection structure 12 retains the detachable characteristics of the connector 3. When maintaining and replacing the main frame 2 or the sub-frame 1 in the future, it is only necessary to loosen the connector 3 for adjustment or disassembly without damaging the main structure or window frame components, thus reducing maintenance costs and secondary damage.

[0044] In one embodiment, each first connecting hole 111 has a connecting structure 12 on both sides of the sub-frame 11 in the circumferential direction.

[0045] In terms of the structural composition of the window frame mounting assembly 100, the sub-frame 11 has connecting structures 12 on both sides of each first connecting hole 111 in the circumferential direction. These connecting structures 12 are integrally or fixedly connected to the sub-frame 11 and are used to connect to the main structure. At the same time, the sub-frame 11 has multiple first connecting holes 111 in the circumferential direction, and the first connecting holes 111 are elongated holes. The main frame 2 has second connecting holes 201 corresponding to the first connecting holes 111. The connector 3 can pass through the first connecting holes 111 and the second connecting holes 201 in sequence and lock the sub-frame 11 and the main frame 2, together forming a complete window frame installation connection and fixing system.

[0046] Its working principle is as follows: during the window frame installation process, the sub-frame 1 is first placed inside the window opening of the main structure. The sub-frame 11 is then connected and fixed to the main structure through the connecting structures 12 on both sides of each first connecting hole 111 around the circumference, so that the sub-frame 1 is stably assembled in the window opening and each first connecting hole 111 is supported by the connecting structures 12 on both sides. Then, the main frame 2 is placed into the main frame installation space 10 of the sub-frame 11, so that the second connecting hole 201 of the main frame 2 is aligned with the first connecting hole 111 of the sub-frame 11. Then, the connector 3 is inserted into the two holes and the sub-frame 11 and the main frame 2 are locked together to complete the overall assembly.

[0047] The technical effect is that each first connecting hole 111 is provided with a connecting structure 12 on both sides. On the one hand, it can form symmetrical support for the sub-frame 11 area around the first connecting hole 111, avoiding deformation of the sub-frame 11 due to local stress concentration when the connector 3 is locked, ensuring the alignment accuracy of the first connecting hole 111 and the second connecting hole 201, thereby ensuring the stability of the connection of the connector 3, reducing the connection gap caused by the deformation of the sub-frame 11, and reducing the risk of water leakage. On the other hand, the connecting structures 12 on both sides can evenly distribute the connection points of the sub-frame 1 and the main structure around each first connecting hole 111, making the overall stress of the sub-frame 1 more balanced, enhancing the stability of the connection between the sub-frame 1 and the main structure, while dispersing the stress on the main structure, avoiding excessive stress on a single connection point and damaging the main structure, further reducing the risk of structural damage. In addition, the symmetrically distributed connecting structures 12 can also improve the positioning accuracy of the sub-frame 1 during installation, making it easier to quickly adjust the sub-frame 1 to the preset position. Combined with the elongated hole fine adjustment function of the first connecting hole 111 and the second connecting hole 201, the installation and adjustment time is shortened.

[0048] In one embodiment, the length direction of the connecting structure 12 is parallel to the length direction of the connector 3 body.

[0049] In terms of the structural composition of the window frame mounting assembly 100, the length direction of the connecting structure 12 located on the outer periphery of the sub-frame 11 and used for connection with the main structure is parallel to the length direction of the connecting piece 3 body used for passing through the first connecting hole 111 of the sub-frame 11 and the second connecting hole 201 of the main frame 2 to lock the sub-frame 11 and the main frame 2. At the same time, the connecting structure 12 is distributed along the circumference of the sub-frame 11, and each first connecting hole 111 is provided on both sides of the circumference of the sub-frame 11. The first connecting hole 111 is an elongated hole with its length direction parallel to the circumference of the sub-frame 11, and the second connecting hole 201 is an elongated hole with its length direction perpendicular to the circumference of the sub-frame 11. Together, they form a cooperative connection system between the sub-frame 1 and the main structure, and between the sub-frame 1 and the main frame 2.

[0050] Its working principle is as follows: when installing the window frame, the sub-frame 1 is first placed in the window opening of the main structure. A fixed connection is established with the main structure through the connecting structure 12, which is parallel to the length direction of the connector 3, so that the sub-frame 1 forms a stable support in the window opening. Since the connecting structure 12 and the connector 3 are parallel in length direction, they work together in the direction of force to avoid the sub-frame 1 from tilting due to misalignment of the direction of force. Then, the main frame 2 is placed into the main frame installation space 10 of the sub-frame 11, so that the second connecting hole 201 of the main frame 2 is aligned with the first connecting hole 111 of the sub-frame 11. Then, the connector 3 is inserted into the two holes and locked to the sub-frame 11 and the main frame 2 to complete the overall assembly.

[0051] The technical advantage lies in the fact that the design of the connecting structure 12 and the connector 3 being parallel in length direction ensures that the fixing force of the connecting structure 12 on the sub-frame 1 and the locking force of the connector 3 on the sub-frame 1 are transmitted in the same direction. This avoids local twisting or deformation of the sub-frame 1 due to inconsistent force directions, ensuring the alignment accuracy of the first connecting hole 111 and the second connecting hole 201, reducing installation difficulties caused by hole misalignment, and improving assembly efficiency. At the same time, the stable force state reduces the gap between the sub-frame 1 and the main frame 2 caused by deformation, reducing the risk of rainwater infiltration. On the other hand, the connecting structures 12, which are distributed circumferentially along the sub-frame 11 and located on both sides of the first connecting hole 111, combined with the length direction parallel to the connector 3, can make the sub-frame 1 more evenly stressed, disperse the force borne by the main structure, avoid excessive force on a single connection point and damage to the main structure, and further reduce the risk of structural damage. In addition, this design can also improve the ease of positioning the sub-frame 1 during installation. With the bidirectional fine-tuning function of the first connecting hole 111 and the second connecting hole 201, the sub-frame 1 can be quickly fixed and connected to the main and sub-frames 1, shortening the construction time.

[0052] In one embodiment, the sub-frame 11 is a steel plate structure with a thickness of 5mm-8mm.

[0053] In terms of the structural composition of the window frame mounting assembly 100, the sub-frame 11 adopts a steel plate structure with a thickness of 5mm-8mm. The sub-frame 11 is the core load-bearing component of the sub-frame 1. The sub-frame 1 also includes multiple connecting structures 12 and multiple first connecting holes 111 arranged sequentially along the circumference of the sub-frame 11. The connecting structures 12 are located on the outer peripheral wall of the sub-frame 11 for connecting with the main structure. The first connecting holes 111 allow the connectors 3 to pass through to connect with the main frame 2. The interior of the sub-frame 11 forms a main frame mounting space 10 for installing the main frame 2. Together with the main frame 2 and the connectors 3, it constitutes a complete window frame mounting assembly 100.

[0054] Its working principle is as follows: during the window frame installation process, the sub-frame 11, which is made of steel plate and has a thickness of 5mm-8mm, is first connected and fixed to the window opening of the main structure through the connecting structure 12 on the outer peripheral wall. The strength of the steel plate and the thickness of 5mm-8mm enable the sub-frame 11 to stably withstand the fastening force of the connecting structure 12 without deformation during the fixing process. After the sub-frame 11 is fixed, the main frame 2 is placed into the main frame installation space 10 inside it. Then, the connector 3 is sequentially passed through the first connecting hole 111 of the sub-frame 11 and the second connecting hole 201 of the main frame 2 and locked. The steel plate structure and specific thickness of the sub-frame 11 ensure that the alignment accuracy of the first connecting hole 111 and the second connecting hole 201 is maintained when the connector 3 is locked, so as to avoid the hole displacement caused by the deformation of the sub-frame 11, which affects the connection stability.

[0055] The technical advantages are that the steel plate structure has high strength, deformation resistance, and corrosion resistance. The thickness of 5mm-8mm can provide sufficient structural support for the sub-frame 11, preventing the sub-frame 11 from bending or deforming during the installation and fixing stage due to the tightness of the connecting structure 12 or due to temperature changes and external impacts during long-term use. It can also avoid the overall weight of the sub-frame 1 exceeding the standard due to excessive thickness, which would increase the difficulty of construction and handling and the installation burden. At the same time, the structural stability of the steel plate ensures the positional accuracy of the first connecting hole 111 on the sub-frame 11, reducing the adjustment process when aligning the main frame 2 and the sub-frame 1. Combined with the fine-tuning function of the elongated hole in the previous solution, it further improves the assembly efficiency of the window frame. Moreover, the deformation resistance of the steel plate can effectively prevent gaps between the main frame 2 and the sub-frame 1 due to the deformation of the sub-frame 11. Combined with the sealing assistance of the connecting structure 12, it significantly reduces the risk of rainwater infiltration. In addition, the durability of the steel plate material can extend the overall service life of the window frame installation component 100 and reduce the maintenance and replacement costs caused by damage to the sub-frame 11 in the later stage.

[0056] In one embodiment, the connecting structure 12 is fixedly connected to the sub-frame 11 or detachably connected.

[0057] Specifically, in the window frame installation structure, the sub-frame 11, as a prefabricated core component adapted to the window opening of the main structure, relies on the connecting structure 12 for its connection with the main frame 2. The connecting structure 12 and the sub-frame 11 can be either fixedly connected or detachably connected. In the fixed connection form, the connecting structure 12 can be rigidly integrated with the sub-frame 11 using metal welding, integrated die casting, or high-strength non-detachable bolts. The mating end of the connecting structure 12 on the main frame 2 has pre-set slots, bolt holes, or sealant grooves that match the contour of the main frame 2 to ensure... The positional accuracy and sealing foundation of the main frame 2 during docking; in the detachable connection form, the connection structure 12 is divided into a pre-installed section and a docking section. The pre-installed section forms a detachable preliminary positioning with the sub-frame 11 through methods such as threaded pre-embedding, elastic buckle pre-installation, or tenon and mortise base fixing. The docking section is fixed to the main frame 2 through methods such as screws and adhesives. During on-site construction, the docking section and the pre-installed section only need to be connected by buckle engagement, tightening of detachable bolts, or tenon and mortise insertion. During later maintenance, the main frame 2 and the sub-frame 11 can be separated by removing bolts and separating buckles.

[0058] In one embodiment, the connecting structure 12 is welded to the sub-frame 11; or, the connecting structure 12 is threadedly connected to the frame.

[0059] Specifically, in the window frame installation structure, the sub-frame 11, as a prefabricated window opening adapter component, is connected to the main frame 2 of the door and window through two types of connection structures 12. The first is a welded connection, in which the connection structure 12 uses a metal connector 3 of the same material as the sub-frame 11 (such as aluminum alloy or steel). During the factory prefabrication stage, the connector 3 is fixed to the pre-set welding point on the inner side of the sub-frame 11 by full welding or spot welding. The end of the connector 3 is pre-set with a slot or bolt hole that matches the main frame 2, ensuring that the connection structure 12 and the sub-frame 11 form a rigid integrated structure. The second is a threaded connection, in which the connection structure 12 is divided into a pre-installed section and a butt section. The pre-installed section has external threads machined on the outside, and the sub-frame 11 has pre-set mounting holes with internal threads at the corresponding positions. The pre-installed section of the connection structure 12 is fixed to the sub-frame 11 by thread engagement. The butt section has pre-reserved screw holes or buckle structures for connection with the main frame 2, and the thread fit accuracy meets the requirements for anti-loosening (such as using fine threads or adding anti-loosening washers).

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
