Description

Technical Field

[0001] This utility model belongs to the field of wooden window frame connection technology, specifically relating to a corner connection structure for a wooden window frame. Background Technology

[0002] The main raw material for wooden window frames is wood, with cedar wood being widely used due to its unique advantages. Cedar wood is lightweight, strong, and resilient, effectively withstanding external forces to ensure the stability and safety of the window. Furthermore, cedar wood has excellent resistance to decay and insects, resisting the erosion of decay fungi and the attack of pests, extending the lifespan of the window frame. At the same time, the color and texture of cedar wood also make it an aesthetically pleasing window frame material, adding a natural touch and charm to the window.

[0003] Traditional wooden window frames present numerous inconveniences during transportation and installation, such as high transportation costs, complex installation processes, and long installation cycles. Furthermore, traditional connection methods often have limited load-bearing capacity, and the aesthetics and structural stability at corners need improvement. Utility Model Content

[0004] The purpose of this invention is to provide a corner connection structure for wooden window frames to solve the connection methods and installation problems of wooden window frames in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A corner connection structure for a wooden window frame includes two splicing pieces and a corner bracket, which are spliced ​​together. The splicing pieces include an outer panel, a web and a web block are installed below the outer panel, and an inner panel is installed below the web and web block. A filling groove is formed between the outer panel, the inner panel, the web, and the web block, and a corner bracket is installed inside the filling groove.

[0007] Furthermore, the corners between the corner brackets 15 are 90°. One side of each of the two splicing pieces has a 45° cut. When the two splicing pieces are completely wrapped around both ends of the corner bracket through the filling groove, the included angle between the two splicing pieces is 90°, thereby enhancing the tightness of the splice and the stability of the structure. This splicing design simplifies the installation process and improves installation efficiency. As a connector, the standardized size and shape of the corner bracket makes the splicing process more convenient, reduces potential errors and complexity during installation, enhances the load-bearing capacity of the connection, and ensures the stability of the structure.

[0008] Furthermore, the corner bracket has threaded holes on both sides, and the outer side of the belly block has countersunk holes. After the cut surfaces of the two splicing pieces coincide, the threaded holes on both sides of the corner bracket will be concentric with the countersunk holes at both ends of the belly block. With the threaded holes on both sides of the corner bracket concentric with the countersunk holes at both ends of the belly block, the connecting bolts are tightened into the threaded holes inside the countersunk holes, avoiding stress concentration caused by misalignment, resisting external loads and deformation, and improving the overall structural durability and connection strength.

[0009] The technical solution of this utility model has the following beneficial effects:

[0010] 1. The two splicing pieces are completely wrapped around both ends of the corner bracket through the filling groove, with the included angle between the two splicing pieces being 90°, thereby enhancing the tightness of the splice and the stability of the structure. This splicing design simplifies the installation process and improves installation efficiency. As a connector, the standardized size and shape of the corner bracket makes the splicing process more convenient, reduces possible errors and complexities during installation, enhances the load-bearing capacity of the connection, and ensures the stability of the structure.

[0011] 2. The design of the cross-section and the reasonable structural layout of this splicing scheme improve the utilization rate of materials and ensure that sufficient strength is provided while minimizing material waste. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0017] Example 1:

[0018] refer to Figure 1A corner connection structure for a wooden window frame includes two splicing pieces and a corner bracket 15. The two splicing pieces are spliced ​​with the corner bracket 15. The splicing pieces include an outer panel 10. A web plate 12 and a web block 13 are installed below the outer panel 10. An inner panel 11 is installed below the web plate 12 and the web block 13. A filling groove 17 is formed between the outer panel 10, the inner panel 11, the web plate 12, and the web block 13. The corner bracket 15 is installed inside the filling groove 17.

[0019] In the above scheme, the corner brackets 15 form a 90° angle. Two splicing pieces are inserted into the two ends of the corner brackets 15, that is, the corner brackets 15 are inserted into the filling groove 17 formed between the outer panel 10, inner panel 11, web 12, and web block 13. One side of the splicing pieces has a 45° cut. When the two splicing pieces are completely wrapped around the two ends of the corner brackets 15 through the filling groove 17, that is, the included angle between the two splicing pieces is 90°, thereby enhancing the tightness of the splice and the stability of the structure. This splicing design simplifies the installation steps and improves installation efficiency. As a connector, the standardized size and shape of the corner brackets 15 make the splicing process more convenient, reduce possible errors and complexities during installation, enhance the load-bearing capacity of the connection, and ensure the stability of the structure. With the design of the cut surfaces and the reasonable structural layout, this splicing scheme improves the utilization rate of materials, ensuring that sufficient strength is provided while minimizing material waste.

[0020] refer to Figure 2 After the cut surfaces of the two splicing pieces overlap, the corner bracket 15 is hidden within the filling groove 17 and is not visible. The corner bracket 15 is cleverly concealed within the filling groove 17, avoiding exposed metal parts or connectors at the splicing point, making the overall structure look cleaner and smoother, and enhancing the product's aesthetics and visual appeal. As a connector, the corner bracket 15, while concealed, still plays its role in fixing and supporting, ensuring a tight connection and stability between the splicing pieces, resulting in a robust structure that is not easily deformed. This design maintains the structural strength while avoiding the risk of collision or damage that could occur due to exposed corner bracket 15, thus improving the overall lifespan of the product structure.

[0021] Further reference Figure 1 The corner bracket 15 has threaded holes 16 on both sides, and the outer side of the belly block 13 has countersunk holes 14.

[0022] After the cut surfaces of the two splicing parts overlap, the threaded holes 16 on both sides of the corner bracket 15 will be concentric with the countersunk holes 14 at both ends of the web block 13. The connecting bolts are tightened into the threaded holes 16 inside the countersunk holes 14, which avoids stress concentration caused by misalignment, resists external loads and deformation, and improves the durability and connection strength of the overall structure.

[0023] The specific implementation process of this utility model is as follows:

[0024] The corner bracket 15 is inserted into the filling groove 17 formed between the outer panel 10, inner panel 11, web 12, and web block 13. The two splicing pieces are completely wrapped around the two ends of the corner bracket 15 through the filling groove 17, that is, the included angle between the two splicing pieces is 90°. The threaded holes 16 on both sides of the corner bracket 15 will be concentric with the countersunk holes 14 at the two ends of the web block 13. The connecting bolts are tightened into the threaded holes 16 inside the countersunk holes 14.
