Description
Technical Field
[0001] This invention belongs to the field of building technology, specifically, it relates to the construction of corner splicing nodes for large-size non-uniform thickness glazed curtain walls. Background Technology
[0002] Driven by the demand for the integration of decoration and function in modern architecture, large-format non-uniform thickness glazed tile curtain walls have gained widespread application due to their unique advantages. These curtain walls not only possess the decorative and cultural attributes of glazed tile, providing rich visual layers to building facades, but their large-format design also reduces the number of seams, enhancing overall aesthetics and sealing. Furthermore, the non-uniform thickness structure allows for flexible adjustment of thickness according to the stress requirements and thermal insulation needs of different parts of the building, adapting to the performance requirements of irregularly shaped building facades or specific functional areas. This makes them an important choice for optimizing the appearance and improving the overall performance of high-rise and landmark buildings.
[0003] However, current corner splicing of large-size, non-uniform thickness glazed curtain walls typically relies on a combination of adhesive and bolts. This method provides fixation at a single location, and over long-term use, temperature changes cause thermal expansion and contraction between the glazed curtain wall and connecting components, leading to gaps between the bolts and mounting holes. Repeated wind loads exert continuous lateral impact on the corner joints, exacerbating bolt loosening. Furthermore, the structural weight of the large curtain wall acts on a single fixation point for extended periods, concentrating stress on the bolts. These combined factors ultimately result in loosening of the corner splicing joints, and in severe cases, even detachment, posing a significant threat to building safety and the curtain wall's lifespan.

[0010] In a preferred embodiment of the present invention, limit seats are installed at both ends of the limit block, and a pair of fixed seats are installed at the center of the limit block. A lead screw shaft is installed through the fixed seat and the limit seat. The lead screw shaft is slidably connected to the slide.

[0012] In a preferred embodiment of the present invention, a timing frame is installed on the top of the slide block, and push rods are installed at both ends of the timing frame.

Furthermore, the lifting groove and lifting slope drive the top block to apply continuous pressure to the inner wall of the locking groove, significantly enhancing the tightness of the connection and making the fit between components more secure, reducing the possibility of loosening. The pressing groove creates a tight compression between the top block and the locking block, fundamentally limiting the tendency of the top block to detach through their interaction, avoiding the risk of separation due to external forces. These three functions work together synergistically, not only achieving stable positioning between the connecting frame, limiting blocks, and outer casing, but also improving the overall structural reliability from multiple dimensions. It also enhances the deformation resistance at the corners of the curtain wall, ensuring stable bearing of various loads during long-term use and providing a solid guarantee for the safe operation of large-size, non-uniform thickness glazed curtain walls.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.
[0021] like Figures 1 to 9 As shown, the corner splicing node structure of the large-size non-uniform thickness glazed curtain wall includes the non-uniform thickness glazed curtain wall 2 and the outer cover 1 wrapped around the outer wall.
[0022] A connecting frame 3 is installed on the side wall of the outer cover 1. A snap-fit groove 5 is provided on the connecting frame 3. A snap-fit block 6 is installed at the inlet of the snap-fit groove 5. The connecting frame 3 is provided with a limit block 9, a pair of slide blocks 13 are slidably arranged on the limit block 9, a pair of top plates 17 are provided on the limit block 9, and a top block 18 is installed on the top plate 17. The slide blocks 13 are used to drive the limit block 9 to have a horizontal sliding driving force, and the bottom of the top plate 17 is slidably connected to the combination groove opened on the limit block 9. The combined groove is composed of a feed groove 31, a lifting groove 32, and a pressing groove 33 connected end to end. The feed groove 31 and the pressing groove 33 are inclined at opposite angles. The feed groove 31 is used to guide the top block 18 to move into the locking groove 5. A lifting slope 30 is installed on the limiting block 9, and the lifting groove 32 is located on the lifting slope 30, while the pressing groove 33 is located on the top of the lifting slope 30. The lifting groove 32 is horizontal and is used to lift the top block 18 and press it against the inner side wall of the locking groove 5. The pressing groove 33 is used to guide the side wall of the top block 18 to press against the side wall of the locking block 6.
[0023] like Figures 1 to 9 As shown in the specific embodiment, several pairs of reinforcing plates 4 are installed on the side wall of the connecting frame 3. These pairs of reinforcing plates 4 are interconnected with the side wall of the outer cover 1, and all pairs of reinforcing plates 4 are triangular. By setting triangular reinforcing plates 4 between the connecting frame 3 and the outer cover 1, the inherent stability of the triangular structure is utilized to significantly enhance the connection strength between the connecting frame 3 and the outer cover 1. This effectively disperses the force at the connection between the outer cover 1 and the connecting frame 3, preventing local structural deformation or cracking caused by external forces such as the curtain wall's own weight and wind pressure. At the same time, it extends the service life of the connection parts and ensures the long-term stable protective effect of the outer cover 1 on the non-uniform thickness glazed curtain wall 2.
[0024] like Figures 1 to 9 As shown, furthermore, a limiting plate 7 is installed on the inner wall of the connecting frame 3. A limiting groove 8 is formed on the limiting plate 7. The limiting groove 8 and the limiting groove 8 of the adjacent limiting plate 7 cooperate to form a complete groove. A limiting block 9 is inserted into the groove to limit the relative sliding of the two outer covers 1. By forming a complete groove through the cooperation of the limiting groove 8 on the limiting plate 7 and inserting the limiting block 9, the relative sliding of the two outer covers 1 during the splicing process can be precisely limited. This effectively avoids misalignment of the curtain wall corner splicing caused by the displacement of the outer covers 1, ensures the initial positioning accuracy of the outer covers 1 at the corner, provides a positional reference for the subsequent precise assembly of various components, reduces splicing errors, and improves the overall assembly efficiency.
[0025] like Figures 1 to 9As shown, furthermore, a pair of connecting plates 10 are installed on the limiting block 9, and a base plate 11 is installed at the end of the pair of connecting plates 10. A pair of mounting holes 12 are installed on the base plate 11, which facilitates interconnection with other structures. The cross-sectional area at the connection between the connecting plate 10 and the base plate 11 is larger than the cross-sectional area at other locations. The above structure not only expands the compatibility of the corner splicing node with other building structures, enabling the node to flexibly connect with different auxiliary support structures, but also enhances the load-bearing capacity of the connection part by increasing the cross-sectional area at the connection between the connecting plate 10 and the base plate 11. It can effectively withstand the external force transmitted when the base plate 11 is connected to the external structure, avoid the breakage at the connection between the connecting plate 10 and the base plate 11 due to excessive local stress, and ensure the load-bearing stability of the overall structure.
[0026] Example 2: The difference between the above embodiments and this embodiment is that: Figures 1 to 9 As shown, limit seats 15 are installed at both ends of the limit block 9, and a pair of fixed seats 36 are installed at the center of the limit block 9. A lead screw shaft 14 is installed through the fixed seat 36 and the limit seat 15. The lead screw shaft 14 is slidably connected to the slide 13. A hexagonal block 35 is welded to the outer wall of the lead screw shaft 14 located on the side wall of the fixed seat 36 to facilitate the rotation of the lead screw shaft 14. A limit rod 16 is installed on the side wall of the limit seat 15, and the limit rod 16 is movable through the slide 13. The hexagonal block 35 provides a convenient operating part for the rotation of the lead screw shaft 14, which can be easily driven without the need for complicated tools, thus improving the assembly convenience. At the same time, the movable through-fitting of the limit rod 16 and the slide 13 can accurately limit the movement trajectory of the slide 13, ensuring that the slide 13 slides horizontally along the axial direction of the lead screw shaft 14, avoiding the slide 13 from deviating or jamming during movement, and providing a reliable guarantee for the stable driving of the subsequent top plate 17.
[0027] like Figures 1 to 9 As shown in the specific embodiment, a positioning rod 22 is vertically inserted into the bottom of the slide block 13. A synchronization plate 21 is installed at the bottom of the positioning rod 22, and an insertion rod 20 is installed on the side wall of the synchronization plate 21. A pair of positioning blocks 19 are movably inserted through the insertion rod 20 and installed on the side wall of the top plate 17. Through the cooperation of the positioning rod 22, the synchronization plate 21, the insertion rod 20 and the positioning blocks 19, the movement of the slide block 13 is synchronously transmitted to the two top plates 17, which can effectively ensure the synchronicity of the two top plates 17 during the movement process, avoid splicing deviation caused by the excessive speed or offset of one side of the top plate 17, ensure the consistency of the position when the top block 18 is subsequently connected to the snap-fit groove 5, and further improve the accuracy and stability of the corner splicing.
[0028] like Figures 1 to 9As shown, a timing frame 23 is further installed on the top of the slide block 13, and push rods 24 are installed at both ends of the timing frame 23. The push rods 24 are in a vertical state, and a sleeve 25 is movably inserted through the bottom of the push rod 24. The sleeve 25 slides against the side wall of the top plate 17. The push rod 24 is used to drive the slide block 13 to slide horizontally. There is a pair of sliding grooves 27 on the top plate 17. The pair of sliding grooves 27 are on the same straight line. A slider 26 is slidably installed on the sliding groove 27. The bottom of the slider 26 is connected to the bottom of the sleeve 25. The bottom of the push rod 24 is movably inserted through the slider 26. The coordination between the synchronous frame 23 and the push rod 24 further enhances the driving stability of the slide block 13 on the top plate 17. The vertically arranged push rod 24 ensures the accurate direction of the driving force and avoids the dispersion of force. The sliding cooperation between the sleeve 25, the slider 26 and the slide groove 27 not only realizes the flexible connection between the push rod 24 and the top plate 17, but also restricts the movement direction of the top plate 17 through the guiding effect of the slide groove 27 on the slider 26, ensuring that the top plate 17 always slides along the preset trajectory, effectively preventing the top plate 17 from tilting or misaligning during the movement, and improving the reliability of the driving structure.
[0029] like Figures 1 to 9 As shown, a baffle 28 is installed on the push rod 24 located on the outer wall of the insert 25. The baffle 28 is in the shape of a boss. A compression spring 29 is also sleeved on the push rod 24 located on the outer wall of the insert 25. One end of the compression spring 29 is engaged with the side wall of the baffle 28, and the other end of the compression spring 29 is engaged with the end face of the insert 25. The compression spring 29 is used to drive the top plate 17 to slide and connect with the feed groove 31. The design of the baffle 28 and the compression spring 29 can provide a continuous and stable preload for the top plate 17, so that the bottom of the top plate 17 is always tightly attached to the feed groove 31 on the limiting block 9, avoiding gaps between the top plate 17 and the feed groove 31 due to vibration, external impact, etc., thereby preventing the top plate 17 from deviating from its movement trajectory or getting stuck.
[0030] like Figures 1 to 9 As shown, a protrusion 34 is further installed at the bottom of the top plate 17. The protrusion 34 is slidably connected to the feed groove 31, and the diameter of the protrusion 34 is adapted to the width of the feed groove 31. By setting the diameter of the protrusion 34 and the width of the feed groove 31 to be adapted sizes, it can be ensured that there is no obvious gap when the protrusion 34 slides in the feed groove 31, effectively avoiding the left and right deviation or jamming of the protrusion 34 during the sliding process, ensuring the accuracy of the movement trajectory of the top plate 17, and thus enabling the top block 18 on the top plate 17 to accurately extend into the snap-fit groove 5 of the connecting frame 3, improving the docking accuracy of the top block 18 and the snap-fit groove 5, reducing splicing errors, and ensuring the subsequent extrusion and fixing effect.
[0031] The implementation principle of the corner splicing node structure for large-size non-uniform thickness glazed curtain walls of the present invention is as follows: When constructing the corner splicing node of a large-size non-uniform thickness glazed curtain wall, the basic structure must first be assembled. The outer cover 1 is wrapped around the outer wall of the non-uniform thickness glazed curtain wall 2. At the same time, a connecting frame 3 is installed on the side wall of the outer cover 1, and a stable connection between the connecting frame 3 and the outer cover 1 is achieved through several pairs of triangular reinforcing plates 4. The triangular structure effectively improves the deformation resistance of the connection part, laying a stable structural foundation for subsequent splicing. Subsequently, using the limiting groove 8 on the limiting plate 7 on the inner side wall of the connecting frame 3, the limiting block 9 is inserted into the complete groove formed by the cooperation of adjacent limiting plates 7. The limiting block 9 restricts the relative sliding between the two outer covers 1, ensuring the initial positioning of the outer cover 1 at the corner. The connecting plate 10 and the base plate 11 on the limiting block 9 can be connected to other related structures through the mounting holes 12 on the base plate 11, further expanding the connection adaptability of the overall structure. Moreover, the larger cross-sectional area at the connection between the connecting plate 10 and the base plate 11 can enhance the load-bearing capacity of this part and avoid damage caused by excessive local stress.
[0032] Based on the above basic assembly, by rotating the hexagonal block 35 on the side wall of the lead screw shaft 14 of the fixed seat 36 at the center position of the limiting block 9, the lead screw shaft 14 is driven to rotate. Since the lead screw shaft 14 is slidably connected to the slide 13, and the limiting rod 16 on the limiting seat 15 plays a guiding and limiting role on the slide 13, the slide 13 slides horizontally along the axial direction of the lead screw shaft 14. During the sliding process of the slide 13, the synchronous frame 23 at its top will drive the push rods 24 at both ends to move synchronously. The push rod 24 forms a sliding fit with the slide groove 27 on the top plate 17 through the bottom movable insert 25 and the slider 26 connected to the bottom of the insert 25, thereby pushing the top plate 17 to move accordingly. At the same time, the positioning rod 22 at the bottom of the slide 13 is connected to the insert rod 20 through the synchronous plate 21. The positioning block 19 that moves through the insert rod 20 is installed on the side wall of the top plate 17. This structure can ensure the synchronicity of the movement of the top plates 17 on both sides and avoid splicing deviation due to inconsistent movement on one side. In addition, the compression spring 29 located on the push rod 24 on the outer side wall of the sleeve 25 is engaged at one end with the side wall of the baffle 28 and at the other end with the end face of the sleeve 25. Under the elastic force of the compression spring 29, it can always provide the top plate 17 with a pre-tightening force toward the limiting block 9, ensuring that the protrusion 34 at the bottom of the top plate 17 and the combined groove (composed of the feed groove 31, the lifting groove 32 and the pressing groove 33) on the limiting block 9 maintain a stable sliding connection. Moreover, the diameter of the protrusion 34 is adapted to the width of the feed groove 31, which can effectively prevent jamming or displacement during the sliding process.
[0033] As the slide block 13 continues to drive the top plate 17 to move, the protrusion 34 at the bottom of the top plate 17 first slides along the feed groove 31 in the combination groove. The inclined structure of the feed groove 31 guides the top block 18 on the top plate 17 to gradually extend into the snap-fit groove 5 of the connecting frame 3, realizing the initial docking of the top block 18 with the snap-fit groove 5. When the protrusion 34 slides to the lifting groove 32, since the lifting groove 32 is located on the lifting slope 30 and is in a horizontal state, it will drive the top plate 17 and the top block 18 to be lifted upward, so that the top block 18 is tightly pressed against the inner wall of the snap-fit groove 5. The pressing force between the top block 18 and the inner wall of the snap-fit groove 5 further strengthens the connecting frame 3. The tightness of the connection between the top block 18 and the limiting block 9; when the protrusion 34 continues to slide to the pressing groove 33, the opposite tilt angle of the pressing groove 33 and the feeding groove 31 will guide the side wall of the top block 18 to be pressed towards the locking block 6 at the inlet of the locking groove 5. The pressing force between the top block 18 and the locking block 6 is used to restrict the top block 18 from coming out of the locking groove 5, and finally realize the multiple stable limiting between the connecting frame 3, the limiting block 9 and the outer cover 1, so as to ensure the overall structural stability of the corner splicing node of the large-size non-uniform thickness glazed curtain wall 2, meet the load-bearing and sealing requirements of the corner of the curtain wall, and adapt to the structural characteristics of the non-uniform thickness curtain wall to achieve reliable splicing.
