Description

Technical Field

[0001] This invention relates to the field of prefabricated building technology, and in particular to an adaptively adjustable arc-shaped metal sheet ceiling design structure. Background Technology

[0002] A suspended ceiling refers to a type of decorative finish on the top of a building's ceiling. Suspended ceilings provide insulation, heat insulation, and sound insulation, and also serve as a concealed layer for electrical, ventilation, air conditioning, communication, fire protection, and alarm wiring and equipment. Existing indoor suspended ceilings typically employ prefabricated structures based on light steel keel. For example, Chinese Patent 202110934770.3 discloses a construction method for a large-span curved suspended ceiling, specifically including the following steps: Step S1: Scanning the interior to create a 3D model; Step S2: Dividing the interior into multiple suspended ceiling keel units based on the 3D model and actual interior conditions; Step S3: Erecting scaffolding on the construction site and laying out the ceiling construction lines; installing the support frame and then the suspended ceiling keel units in sequence; Step S4: Installing silicon ceramic composite panels; Step S5: Applying putty; Step S6: Applying decorative bamboo veneer to complete the construction.

[0003] The current process for making a curved ceiling involves first creating a model of the curved ceiling based on measured room data, then dividing the curved ceiling into several ceiling units, prefabricating curved panels, and finally hanging and splicing the curved panels on-site to form the ceiling surface.

[0004] However, such curved ceilings require high precision in measurement data. If problems arise during the actual installation process, such as changes in the span of the curved ceiling due to inaccurate pre-measured data or additional decorative items added to the building's top, it is difficult to adapt and modify the ceiling design accordingly. Furthermore, effective control of the joints between the curved panels is required during the surface hanging process, making the construction demanding and challenging. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptively adjustable curved metal sheet ceiling design structure, which solves the problems of difficulty in adjusting the ceiling shape and high construction requirements and difficulties in existing curved ceilings.

[0038] Please see Figure 1-6 This invention provides a technical solution: an adaptively adjustable arc-shaped thin metal plate ceiling design structure, comprising:

[0039] Steel frame transfer layer 1;

[0040] The ceiling frame layer includes a main keel 2, a central hanging rod 3, a linkage hanging rod 4, and an edge hanging rod 5. Several main keels 2 are arranged in parallel. The main keels 2 are suspended on the steel frame transition layer 1 by a first hanging rod 21. The top of the central hanging rod 3 is provided with a first threaded rod 31. The first threaded rod 31 passes through the steel frame transition layer 1 and is fixed by a nut. The linkage hanging rods 4 are symmetrically arranged on both sides of the central hanging rod 3. The linkage hanging rods 4 are slidably connected to the main keel 2. A connecting rod 41 is provided between the central hanging rod 3 and the linkage hanging rod 4. One end of the connecting rod 41 is rotatably installed on the central hanging rod 3, and the other end is rotatably installed on the linkage hanging rod 4. The edge hanging rods 5 are symmetrically arranged on both sides of the central hanging rod 3. The edge hanging rods 5 are slidably connected to the main keel 2.

[0041] The ceiling surface layer comprises several ceiling panel units 6. Each ceiling panel unit 6 includes a central thin plate 61 and edge thin plates 62 symmetrically arranged on both sides of the central thin plate 61. The central thin plate 61 has an "n"-shaped structure with a central protrusion, while the edge thin plates 62 have a "U"-shaped structure with a central depression. The central thin plate 61 is fixedly installed at the bottom of the central suspension rod 3. A connecting seat 42 is provided at the bottom of the linkage suspension rod 4, and the connecting seat 42 is rotatably installed at the bottom of the linkage suspension rod 4. A first connecting base plate 421 is provided at the bottom of the connecting seat 42. The end of the central thin plate 61 is fixedly installed on the first connecting base plate 421. One end of the edge thin plate 62 contacts the end of the central thin plate 61, and one end of the edge thin plate 62 is fixedly installed on the first connecting base plate 421. One end of the edge thin plate 62 is provided with a bent edge 621, which is fixedly installed at the bottom of the edge suspension rod 5. Both the central thin plate 61 and the edge thin plate 62 are thin metal plates that can deform.

[0042] At least one first hook block 22 is provided on the main keel 2. A first sliding groove 32 corresponding to the first hook block 22 is provided on the back of the central hanging rod 3. The first sliding groove 32 is arranged along the length direction of the central hanging rod 3, and the first hook block 22 is slidably connected in the first sliding groove 32. The first sliding groove 32 extends inward from the lower end of the central hanging rod 3. When installing the central hanging rod 3, the central hanging rod 3 is first slidably connected to the first hook block 22 on the main keel 2, and then the central hanging rod 3 is fixed to the steel frame transition layer 1 through the first threaded rod 31 at the top of the central hanging rod 3. When installing the ceiling surface layer, the bottom of the central hanging rod 3 is welded and fixed to the back of the central thin plate 61. The first hook block 22 can effectively prevent the central hanging rod 3 from swinging laterally, improve the smoothness of the vertical movement of the central hanging rod 3, and the overall stability of the ceiling frame layer.

[0043] Two parallel first hook blocks 22 are installed on the main keel 2 to further enhance the overall stability of the ceiling frame layer.

[0044] A second hook block 43 is provided on the back of the linkage hanging rod 4, and a second sliding groove 23 with a matching shape is provided on the main keel 2. The second hook block 43 is slidably connected in the second sliding groove 23. This allows the linkage hanging rod 4 to slide smoothly along the main keel 2, effectively controlling the smooth deformation of the ceiling surface.

[0045] Angle bracket 44 is provided on the back of the linkage suspension rod 4. The angle bracket 44 includes a baffle 441, which contacts the upper surface of the main keel 2. The angle bracket 44, through the contact of the baffle 441 with the upper surface of the main keel 2, allows the linkage suspension rod 4 to slide smoothly along the main keel 2 and prevents the linkage suspension rod 4 from detaching from the main keel 2. The angle bracket 44 is fixed to the linkage suspension rod 4 by means of screw connection, bonding, or welding.

[0046] The baffle 441 is fixedly installed on the main keel 2 with screws, effectively locking the relative position of the linkage hanging rod 4 and the main keel 2, and ensuring the stability of the ceiling surface shape.

[0047] A third sliding groove 24 is provided below the main keel 2. The top of the edge hanging rod 5 is slidably connected within the third sliding groove 24. A support plate 51 is also provided on the top of the edge hanging rod 5. The support plate 51 contacts the lower surface of the main keel 2 and is fixedly installed on the main keel 2 with screws. The sliding of the edge hanging rod 5 along the main keel 2 can flexibly adjust the position of the end of the edge thin plate 62 and the overall width of the ceiling panel unit 6. After the edge hanging rod 5 moves to the desired position, the support plate 51 is fixed to the main keel 2 with screws to lock the position of the edge hanging rod 5.

[0048] The bottom of the edge hanging rod 5 is provided with a second connecting base plate 52, and the second connecting base plate 52 is provided with a fourth sliding groove. The bent edge 621 is provided with a third hook 622 corresponding to the fourth sliding groove. The third hook 622 is slidably connected in the fourth sliding groove. The second connecting base plate 52 is fixedly installed on the bent edge 621 with screws. When the edge thin plate 62 is adjusted in shape, it can be achieved by sliding the third hook 622 in the fourth sliding groove. After it is moved into place, the second connecting base plate 52 is fixedly installed on the bent edge 621 with screws. The edge thin plates 62 of two adjacent ceiling panel units 6 share one edge hanging rod 5, and the bent edges 621 of the edge thin plates 62 of two adjacent ceiling panel units 6 are connected to the same second connecting base plate 52, which improves the shapeability of the ceiling surface.

[0049] Working principle: A steel frame transition layer 1 is set at the top of the building, and the ceiling surface layer is suspended on the steel frame transition layer 1 through the ceiling frame layer. The shape of the ceiling surface layer is not fixed, and the span can be flexibly adjusted according to the actual installation situation on site. Moreover, the shape of the ceiling surface layer can be flexibly adjusted, resulting in good decorative effect and low construction requirements and difficulty, effectively improving construction efficiency.

[0050] During on-site installation of the ceiling surface layer, several ceiling panel units 6 are set along the length of the main keel 2. The width and shape of the ceiling panel units 6 can be flexibly adjusted to adjust the span of the ceiling surface layer to adapt to the site conditions. When adjusting a single ceiling panel unit 6, the installation height of the central hanging rod 3 is adjusted, causing the central hanging rod 3 to synchronously drive the two side linkage hanging rods 4 to slide horizontally via the connecting rod 41. When the central hanging rod 3 moves upward, the two linkage hanging rods 4 move towards each other, controlling the degree of convexity in the center of the central thin plate 61 and the degree of concavity in the center of the edge thin plate 62. This allows for quick adjustment of the shape of the ceiling panel unit 6.

[0051] Furthermore, the width of the ceiling panel unit 6 can be adjusted by moving and adjusting the edge hanging rod 5. The sliding and pressing adjustment of the width of the ceiling panel unit 6 allows for flexible adjustment of the overall span of the ceiling surface layer, compensating for previous measurement errors and reducing installation difficulty.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
