Description

Technical Field

[0001] This utility model relates to the field of ceiling structure technology, and in particular to a three-dimensional ceiling structure for architectural decoration. Background Technology

[0002] In the field of architectural decoration, the application of three-dimensional suspended ceiling structures is becoming increasingly widespread. They can create layered or zoned visual effects in commercial and residential spaces, effectively concealing structural elements and piping, and enhancing the aesthetics and utilization of the space. As people's demands for architectural decoration continue to rise, higher requirements are being placed on the performance and applicability of three-dimensional suspended ceiling structures, indicating a very broad market prospect.

[0003] Patent document CN222909192U discloses a three-dimensional suspended ceiling structure for architectural decoration. This design utilizes a pair of fixed rods with grooves on their side walls for securing a stop bar. A sliding frame engages with the frame, which contains multiple sliding plates with fixing components. This allows for adjustable lengths of the frame and sliding plates, adapting to different ceiling sizes, reducing the cumbersome cutting of fasteners, and improving the applicability of the ceiling structure. However, this design still has significant drawbacks. Both the frame and sliding plates are plate-like structures, which are prone to elastic deformation under load when used for extended periods. This not only affects the flatness of the ceiling, reducing its decorative effect, but may also cause structural stability issues, posing safety hazards and significantly compromising the aesthetics and practicality of the ceiling, thus limiting its application in high-quality architectural decoration projects.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Reference Figure 1-2 This utility model provides a three-dimensional ceiling structure for architectural decoration, specifically including two fixed frames 1, two telescopic plates 2, one diagonal support 3, and multiple tie rod assemblies 4.

[0045] The system comprises two fixed frames 1, one connected to the wall and the other to the roof. During use, the connection positions of the two fixed frames 1 to the wall and the roof are determined. Corresponding mounting holes are marked on the wall and roof. Expansion bolts 9 and other fasteners are used to securely install the fixed frames 1 to the wall and roof, ensuring stability and providing a solid foundation for the entire ceiling structure. Specifically, expansion bolts 9 are installed at both ends of the fixed frames 1 to firmly fix them to the wall and roof. When installing the expansion bolts 9, holes are first drilled in the wall and roof. Then, the expansion tube of the expansion bolt 9 is inserted into the hole, and the bolt is rotated with a screwdriver or wrench to expand the expansion portion and tightly fit it against the hole wall, thus achieving a stable installation of the fixed frames 1.

[0046] A horizontal telescopic plate 2 is fixedly connected to a fixed frame 1 connected to the wall, while a vertical telescopic plate 2 is fixedly connected to a fixed frame 1 connected to the roof. The fixing between the fixed frame 1 and the telescopic plate 2 can be achieved through welding, bolting, or other methods to ensure the connection strength between the telescopic plate 2 and the fixed frame 1. The ends of the two telescopic plates 2 furthest from the fixed frame 1 are connected to each other. The telescopic plate 2 is used to accommodate ceiling sizes with different height or length requirements, improving its applicability during use. Panels (not shown in the figure) or decorative panels (not shown in the figure) are fixed to the side walls of the telescopic plate 2, further forming a three-dimensional ceiling structure.

[0047] Diagonal supports 3 are fixedly connected between the two fixed frames 1. The diagonal supports 3 are usually made of steel with certain strength and rigidity, such as steel pipes or angle steel. One end of the diagonal support is connected to the fixed frame 1 on the wall side, and the other end is connected to the fixed frame 1 on the roof side. During installation, it should be ensured that the connection between the diagonal support 3 and the fixed frame 1 is firm and reliable. It can be fixed by welding or bolting to enhance the stability and deformation resistance of the entire ceiling structure.

[0048] The upper end of the tie rod assembly 4 is fixedly connected to the inclined support 3, and the lower end of the tie rod assembly 4 is fixedly connected to the telescopic plate 2 arranged in the horizontal direction. The tie rod assemblies 4 are arranged at intervals along the length of the inclined support 3, preferably at equal intervals.

[0049] By setting up the tie rod assembly 4, the telescopic plate 2, which is set in the horizontal direction, is pulled upward to reduce elastic deformation caused by gravity and load. This improves the flatness of the ceiling, thereby enhancing its aesthetics and practicality.

[0050] Specifically, refer to Figure 3-4 The tie rod assembly 4 includes a tie rod 41, a first connecting block 42, and a second connecting block 44. The tie rod 41 is vertically oriented, with first external threads at both its upper and lower ends. The upper end of the tie rod 41 passes through the first connecting block 42, and two first nuts 43 are threadedly connected to the upper end of the tie rod 41, located at the upper and lower ends of the first connecting block 42 respectively, thus fixing the upper end of the tie rod 41 to the first connecting block 42 of the inclined support 3. Similarly, the lower end of the tie rod 41 passes through the second connecting block 44 and is threadedly connected to two first nuts 43, located at the upper and lower ends of the second connecting block 44 respectively, achieving a fixed connection between the lower end of the tie rod 41 and the telescopic plate 2. The number and spacing of the tie rod assemblies 4 are generally determined based on the actual dimensions of the ceiling and the load-bearing requirements, typically with a spacing of approximately 30 to 50 centimeters to ensure that the ceiling structure can evenly distribute the load when under stress, improving overall stability and safety.

[0051] The tie rod 41 is made of high-strength steel, with first external threads at both ends for connection to the first connecting block 42 and the second connecting block 44. Both the first connecting block 42 and the second connecting block 44 are made of angle steel. One side of the first connecting block 42 is fixedly connected to the diagonal support 3 via a fastener 45, which can be a bolt and nut structure. After determining the position of the tie rod 41, holes are drilled in the diagonal support 3, and bolts are passed through the first connecting block 42 and the diagonal support 3, then threaded with nuts to complete the installation of the first connecting block 42. One side of the second connecting block 44 is fixedly connected to the screw 46, while the other side movably passes through the lower end of the tie rod 41. The screw 46 is fixed to one side of the second connecting block 44 and is detachably threaded to the threaded hole 5 on the horizontally oriented telescopic plate 2. This threaded connection facilitates the installation, disassembly, and adjustment of the tie rod assembly 4, allowing for flexible adjustment of the position and angle of the tie rod 41 according to different ceiling design requirements.

[0052] It should be noted that the length of the pull rod 41 varies at different locations, and different lengths of pull rod 41 should be selected according to different usage locations. When it is necessary to fine-tune the length of the pull rod assembly 4, the first nuts 43 at both ends of the pull rod 41 can be loosened first, and then the length of the pull rod 41 extending or retracting from the first connecting block 42 and the second connecting block 44 can be changed by adjusting the pull rod 41. After adjusting to the appropriate position, the first nuts 43 can be tightened to ensure that the pull rod assembly 4 is firmly connected to the inclined support 3 and the telescopic plate 2.

[0053] Reference Figure 2 and Figure 4 The middle part of the fixed frame 1 is recessed towards the telescopic plate 2 to form a connecting cylinder. The telescopic plate 2 is provided with a connecting frame at one end near the fixed frame 1. The connecting frame is a rectangular structure. The connecting cylinder and the connecting frame are connected by multiple connecting components 6.

[0054] The connecting assembly 6 includes a connecting rod 61, a movable ring 63, a flipping rod 64, a reset member, and a retaining ring 65. One end of the connecting rod 61 passes through the connecting cylinder and the connecting frame and is fixedly connected to a baffle 62. The other end is provided with a second external thread, on which a second nut 66 is threaded. The movable ring 63 is slidably connected to the connecting rod 61, and one end of a plurality of flipping rods 64 is hinged to it. The flipping rods 64 are located on the periphery of the connecting rod 61 and are movable between a first position and a second position. In the first position, the flipping rods 64 are parallel to the connecting rod 61 and fit against the periphery of the connecting rod 61. In the second position, the flipping rods 64 are perpendicular to the connecting rod 61 and selectively engage between the connecting cylinder and the baffle 62. The reset member (not shown in the drawings) is located at the hinge axis of the movable ring 63 and is used to drive the flipping rods 64 to move from the first position to the second position. The retaining ring 65 is slidably connected to the connecting rod 61, located between the baffle 62 and the movable ring 63, and selectively abuts against the connecting frame. Optionally, the reset element is a torsion spring located at the hinge axis of the movable ring 63, and the torsion spring is used to drive the flipping rod 64 to move from the first position to the second position.

[0055] When installing the telescopic plate 2, first pass one end of the connecting rod 61 through the connecting cylinder and the connecting frame, and ensure that the baffle 62 is tightly against the wall or roof. Then, under external force, position the tilting rod 64 in the first position. Subsequently, thread the movable ring 63 onto the connecting rod 61, passing it through both the connecting cylinder and the connecting frame. After removing the external force, the tilting rod 64 moves to the second position under the drive of the reset component, engaging between the connecting cylinder and the baffle 62. Next, install the retaining ring on the connecting rod 61 and adjust the position of the retaining ring 65 so that it abuts against the connecting frame. Finally, tighten the second nut 66 at the other end of the connecting rod 61 to ensure that the entire connecting assembly 6 is secure and reliable.

[0056] The telescopic plate 2 includes a fixed plate 21 fixedly connected to the connecting frame and a movable plate 22 fixedly and slidably connected to the slide rails. The fixed plate 21 has slide rails on both sides along its width direction, and the movable plate 22 is slidably connected to the fixed plate 21 via the slide rails. This structure allows the movable plate 22 to slide along the fixed plate 21 in a certain direction, realizing the telescopic function of the telescopic plate 2. Both the movable plate 22 and the fixed plate 21 have threaded holes 5 on their upper surfaces for connecting to the screws 46 on the second connecting block 44, thus achieving a fixed connection between the pull rod assembly 4 and the telescopic plate 2.

[0057] Reference Figure 2 and Figure 6The slide rail has multiple strip holes 23 along its length, and the movable plate 22 has two retaining edges on both sides along its width. These retaining edges are slidably connected to the two slide rails, and each retaining edge has multiple second connecting holes 24. The second connecting holes 24 are connected to the strip holes 23 by fasteners 45. When installing the movable plate 22, the retaining edges of the movable plate 22 are placed into the slide rail, and the position of the movable plate 22 on the fixed plate 21 is adjusted so that the second connecting holes 24 align with the strip holes 23. Then, the movable plate 22 is fixed to the slide rail using the fasteners 45. When the position of the movable plate 22 needs to be adjusted, the fasteners 45 are loosened, the movable plate 22 is slid to the appropriate position, and then the fasteners 45 are tightened again. This allows for flexible adjustment and fixation of the movable plate 22, thus meeting different ceiling sizes and design requirements.

[0058] Reference Figure 2 and Figure 7 This utility model also includes a connecting plate 8, which has two third connecting holes. These third connecting holes are connected to the second connecting holes 24 at the ends of the two movable plates 22 furthest from the connecting frame, respectively, using fasteners 45. The connecting plate 8 is mainly used to enhance the connection strength and stability between the two movable plates 22, preventing excessive deformation or displacement of the movable plates 22 during extension and retraction, and ensuring the integrity and service life of the telescopic plate 2. During installation, the third connecting holes of the connecting plate 8 are aligned with the second connecting holes 24 of the two movable plates 22, and then fastened and fixed using the fasteners 45. The operation is simple and convenient, allowing for quick assembly of all components of the telescopic plate 2.
