Description

Technical Field

[0001] This utility model belongs to the technical field of window sash connecting corner brackets, specifically relating to a connecting corner bracket for window sash profiles. Background Technology

[0002] In traditional wooden window sash connections, the load-bearing capacity of corner brackets is often limited by the grain direction of the material. Bamboo, as a high-quality composite bamboo structural material, exhibits a significant impact on structural strength due to its grain direction. A grain direction alone limits load-bearing capacity, which is particularly evident in the design of window sash corner brackets. Utility Model Content

[0003] The purpose of this invention is to provide a connecting corner bracket for window sash profiles to solve the problems of unidirectional texture and load-bearing capacity in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A connecting corner bracket for a window sash profile includes a mounting plate and a corner block. The corner block is composed of a first corner plate, a second corner plate, and a third corner plate. The first, second, and third corner plates have the same structure. The mounting plate has an internal mounting groove, and any end of the corner block is inserted into the mounting groove. The second and third corner plates are respectively attached to the upper and lower surfaces of the first corner plate. The mounting plate has a countersunk hole on its side, and the first corner plate has a threaded hole on its side.

[0006] Furthermore, the corner block is a right-angled corner. Because the corner block is a right-angled corner, mounting plates can be inserted into both ends to change the mounting angle.

[0007] Furthermore, the first, second, and third corner plates are connected using a specialized structural adhesive. This specialized structural adhesive possesses excellent mechanical properties, enabling it to withstand significant loads and ensuring the strength of the connection points. It also distributes stress evenly, preventing deformation caused by excessive stress at a single point.

[0008] Furthermore, the outer wall of the first corner plate has horizontal bamboo fiber patterns, while the outer walls of the second and third corner plates have vertical bamboo fiber patterns. When the first, second, and third corner plates are assembled, the horizontal bamboo fiber patterns on the first corner plate utilize their high strength in the horizontal direction; simultaneously, the second and third corner plates above and below the first corner plate, under the action of the vertical bamboo fiber patterns, can provide additional support in the vertical direction, thus optimizing the load-bearing distribution of the corner blocks.

[0009] Furthermore, the first corner plate has a first corner groove on both sides, and a connecting block is installed in the first corner groove. The second corner plate and the third corner plate each have a second corner groove on one side for cooperating with the connecting block.

[0010] Furthermore, the depth of the first and second corner slots is half the thickness of the connecting block. This design ensures that the connecting block can be firmly embedded in the two corner slots, thereby improving the splicing accuracy between the corner plates.

[0011] Furthermore, the connecting block and the corner groove are arranged at right angles. This right-angle arrangement ensures accurate connection angles between the corner plates, and the right-angle connection more effectively disperses and resists external forces, thereby improving the overall structural stability. When subjected to vertical and horizontal loads, the right-angle connection better distributes the force to each corner plate, reducing the risk of structural deformation and damage.

[0012] The technical solution of this utility model has the following beneficial effects:

[0013] 1. The horizontal bamboo fiber texture utilizes its high strength in the horizontal direction; simultaneously, the second and third corner plates above and below the first corner plate, under the influence of the vertical bamboo fiber texture, provide additional support in the vertical direction, optimizing the load-bearing distribution of the corner blocks. The combination of these three elements forms a composite structure, giving the corner blocks excellent load-bearing capacity in multiple directions.

[0014] 2. When splicing the first, second, and third corner plates, the right-angled connecting blocks and corner grooves can not only provide positioning but also initially stabilize the installation of the corner plates, making it less likely to cause misalignment or displacement of the installation position.

[0020] 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.

[0021] Example 1:

[0022] refer to Figure 1 and Figure 2 A connecting corner bracket for a window sash profile includes a mounting plate 20 and a corner block. The corner block is composed of a first corner plate 10, a second corner plate 11, and a third corner plate 12 spliced ​​together. The first corner plate 10, the second corner plate 11, and the third corner plate 12 have the same structure. The corner block is a right-angle corner. The mounting plate 20 has a mounting groove 21 inside, wherein any end of the corner block is inserted into the mounting groove 21. The second corner plate 11 and the third corner plate 12 are respectively attached to the upper and lower surfaces of the first corner plate 10.

[0023] In the above scheme, the corner block is composed of a first corner plate 10, a second corner plate 11, and a third corner plate 12 spliced ​​together. This splicing effectively disperses pressure and prevents structural damage caused by excessive stress at a single point. The splicing method allows for adjustment of the plate thickness to suit different application scenarios. The first corner plate 10, second corner plate 11, and third corner plate 12 are connected using a special structural adhesive. This adhesive possesses excellent mechanical properties, can withstand large loads, and ensures the strength of the connection points. It also evenly distributes stress, preventing deformation caused by excessive stress at a single point. The corner block has right-angle corners, allowing mounting plates 20 to be inserted at both ends to change the installation angle. The two ends of the corner block interlock with the mounting grooves 21.

[0024] The angle between the corner pieces can be set between 0° and 180°, depending on the specific needs of use.

[0025] Further reference Figure 2The outer wall of the first corner plate 10 has horizontal bamboo fiber patterns, while the outer walls of the second corner plate 11 and the third corner plate 12 have vertical bamboo fiber patterns. When the first corner plate 10, the second corner plate 11, and the third corner plate 12 are assembled, the horizontal bamboo fiber patterns on the first corner plate 10 utilize their high strength in the horizontal direction; simultaneously, the second corner plate 11 and the third corner plate 12, located above and below the first corner plate 10, provide additional support in the vertical direction under the influence of the vertical bamboo fiber patterns, thus optimizing the load-bearing distribution of the corner piece. The combination of the three forms a composite structure, giving the corner piece excellent load-bearing capacity in multiple directions; compared to a single-direction texture, the interlaced composite texture structure optimizes the load-bearing distribution of the corner piece, thereby increasing its load-bearing performance.

[0026] Further reference Figure 1 The mounting plate 20 has a countersunk hole 22 on its side, and the first corner plate 10 has a threaded hole 16 on its side. The two ends of the corner block are inserted into the mounting groove 21, that is, the countersunk hole 22 and the threaded hole 16 are concentrically fitted. A bolt is installed inside the countersunk hole 22 and enters the threaded hole 16 to complete the connection between the corner block and the mounting plate 20.

[0027] Example 2:

[0028] refer to Figure 3 The first corner plate 10 has a first corner groove 13 on both sides, and a connecting block 14 is installed in the first corner groove 13. The second corner plate 11 and the third corner plate 12 each have a second corner groove 15 on one side for cooperating with the connecting block 14. The depth of the first corner groove 13 and the second corner groove 15 is half the thickness of the connecting block 14.

[0029] In the above scheme, the splicing of the first corner plate 10, the second corner plate 11, and the third corner plate 12 is achieved by first installing a connecting block 14 on each side of the first corner plate 10. The connecting blocks 14 are also connected using a special structural adhesive. The depth of the first corner groove 13 and the second corner groove 15 is half the thickness of the connecting block 14. This design ensures that the connecting block 14 can be firmly embedded in the two corner grooves, thereby improving the splicing accuracy between the corner plates. When installing the second corner plate 11 and the third corner plate 12, they can be directly inserted into the connecting block 14 through the second corner groove 15. The connection between them can withstand greater external forces and pressures, improving the overall structural load-bearing capacity and service life. The cooperation of the connecting block 14, the first corner groove 13, and the second corner groove 15 facilitates the splicing of the first corner plate 10, the second corner plate 11, and the third corner plate 12 by workers, achieving rapid positioning.

[0030] Further reference Figure 3The connecting block 14 and the corner groove are set at right angles. This right-angle setting ensures accurate connection angles between the corner plates, and the right-angle connection more effectively disperses and resists external forces, thereby improving the overall structural stability. When subjected to vertical and horizontal loads, the right-angle connection better distributes the force to each corner plate, reducing the risk of structural deformation and damage. Furthermore, when splicing the first corner plate 10, the second corner plate 11, and the third corner plate 12, the right-angled connecting block 14 and the corner groove not only provide positioning but also help to initially stabilize the installation of the corner plates, reducing the likelihood of misalignment or displacement.

[0031] The specific implementation process of this utility model is as follows:

[0032] A connecting block 14 is installed on each of the two sides of the first corner plate 10. The second corner plate 11 and the third corner plate 12 are installed by directly inserting the second corner groove 15 into the connecting block 14 to complete the assembly of the first corner plate 10, the second corner plate 11 and the third corner plate 12. They are connected by special structural adhesive. The corner block is a right-angle corner that can be inserted into the mounting plate 20 at both ends to change the installation angle. The two ends of the corner block are inserted into the mounting groove 21. The countersunk hole 22 and the threaded hole 16 are concentrically fitted. A bolt is installed in the countersunk hole 22 and enters the threaded hole 16 to complete the connection between the corner block and the mounting plate 20.

The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions can be made to this utility model within its substance and scope of protection.
