[0031] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] Reference Figures 1 to 9 As shown, the present invention provides an ultra-large special-shaped curved ceiling structure, comprising: a conversion layer 1, a laminated ceiling board 2, and a large light box 3.

[0034] The conversion layer 1 is installed on the ceiling of the building structure. The bottom of the outer edge of the conversion layer 1 is formed with multi-layered modeling steps 11. The multi-layered modeling steps 11 are inclined downward toward the outer side of the conversion layer 1.

[0035] The laminated ceiling panel 2 comprises a plurality of layers of special-shaped panels 21 and a caulking circular tube 22 .

[0036] Specifically, a layer of special-shaped plate 21 is installed at the bottom of the multi-layered shaping step 11 and the bottom of the conversion layer 1. The special-shaped plate 21 is arranged at an angle. A closing seam is formed between the upper part of the special-shaped plate 21 of the first layer and the lower part of the special-shaped plate 21 of the last layer. The caulking round tube 22 is embedded in the closing seam. Both ends of the caulking round tube 22 are rotatably installed on the shaping step 11 through the hinged arm 23. The shaping step 11 is installed with a locking member 24 for locking the hinged arm 23.

[0037] A large light box 3, a wheel disc 31 is connected to the bottom of the conversion layer 1. The outer edge of the wheel disc 31 is provided with a plurality of through holes. A suspension rod 32 is installed in the through holes. Two clamping ring plates 33 are respectively attached to the inner and outer sides of the top box plate of the large light box 3. A tie rod 34 is connected between the two clamping ring plates 33. The lower end of the suspension rod 32 is connected to the clamping ring plate 33 outside the large light box 3. The top special-shaped plate 21 is arranged in a circle along the circumferential direction of the large light box 3. A through hole connected to the inner ring holes of the two clamping ring plates 33 is opened in the top box plate. Lamps are installed in the through hole and the inner ring hole in a liftable manner.

[0038] One end of the articulated arm 23 is hinged to the molding step 11. The other end of the articulated arm 23 is connected to an inner lining plate 25. The inner lining plate 25 is arc-shaped and its curvature is adapted to the curvature of the tube wall of the caulking circular tube 22. The inner lining plate 25 extends into the port of the caulking circular tube 22 and presses against the inner wall of the caulking circular tube 22. The other end of the articulated arm 23 is connected to a fastening plate 26. The fastening plate 26 presses against the outer wall of the caulking circular tube 22. The position of the fastening plate 26 corresponds to the position of the inner lining plate 25.

[0039] The fastening plate 26 is provided with a plurality of threaded holes arranged along the circumferential direction of the caulking circular tube 22. A support column is screwed into the threaded hole. One end of the support column is pressed against the outer wall of the caulking circular tube 22.

[0040] A plurality of locking holes are formed at the other end of the hinged arm 23. The plurality of locking holes are arranged at intervals along the circumferential direction of the hinged arm 23. The locking member 24 is detachably mounted on the molding step 11 and inserted into a locking hole.

[0041] The axis of the wheel disc 31 is connected to the conversion layer 1 through a connecting piece.

[0042] The suspension rod 32 is formed with an external thread. Two first screwing members are screwed on the upper end of the suspension rod 32. The two first screwing members are clamped on the wheel disc 31. Two second screwing members are screwed on the lower end of the suspension rod 32. The two second screwing members are clamped on the clamping ring plate 33 outside the large light box 3.

[0043] The tie rod 34 is formed with an external thread. Two third screwing members are screwed on two ends of the tie rod 34 respectively. The two third screwing members on two ends of the tie rod 34 are clamped on two clamping ring plates 33 respectively.

[0044] The present invention provides a construction method of an ultra-large special-shaped curved ceiling structure, comprising the following steps:

[0045] S1. Install a transfer layer 1 on the ceiling of the building structure.

[0046] S2, hoisting the large light box 3, and connecting the wheel 31 on the large light box 3 to the bottom of the conversion layer 1.

[0047] S3. A layer of special-shaped plate 21 is respectively installed at the bottom of the multi-layered shaping step 11 and the bottom of the conversion layer 1, so that a closing seam is formed between the upper part of one special-shaped plate 21 and the lower part of the upper special-shaped plate 21.

[0048] S4, rotating the hinged arm 23 to embed the caulking circular tube 22 in the closing seam.

[0049] S5. Install the locking member 24 on the molding step 11 , and the locking member 24 locks the hinged arm 23 to form the laminated ceiling panel 2 .

[0050] The laminated ceiling panels of the super-large special-shaped curved ceiling structure of the present invention have different degrees of retraction structure, which produces a certain step-down effect. Each step-down uses a caulking round tube as an interface shape. The caulking round tube is relatively long, about 13m, with a diameter of 20cm, and is heavy. The use of an external clamp affects the overall appearance and cannot meet the design requirements. If an ordinary hanger is used for installation, it is necessary to install holes with a certain spacing, which damages the caulking round tube. In addition, the hanger conflicts with the metal surface layer, and the position of the hanger needs to be constantly changed, which makes it difficult to ensure the angle of the caulking round tube and inconvenient to adjust.

[0051] The caulking round tube is rotatably installed on the modeling step of the transfer layer by means of an articulated arm. An inner lining plate is installed on the articulated arm, and the curvature is the same as that of the caulking round tube. The two ends of the caulking round tube are overlapped on the inner lining plate. The inner lining plate can be directly welded and fixed, or it can be made adjustable according to the installation requirements.

[0052] There are two lifting holes on the inner lining plate for temporary installation and removal of caulking circular pipes. After the later positioning is determined, there is no need to disassemble them as a reinforcement measure.

[0053] The articulated arm is installed on the steel structure transfer layer frame through the articulated axis. The number of locking parts can be increased or decreased according to the needs of the project. At the same time, whether to use the reinforcing belt and at what angle to use it can also be determined according to the project.

[0054] On the same side of the inner lining plate of the articulated arm, behind the inner lining plate, a fastening plate is installed, and a hole is opened in the fastening plate for tightening the support column to support the caulking round tube to ensure that the caulking round tube does not slide and at the same time support the roundness of the caulking round tube.

[0055] After installation is complete, the articulated arms at both ends of the caulking circular tube can be adjusted simultaneously or independently to achieve the ultimate installation effect.

[0056] Large light boxes are heavy. Whether it is the holes in the concrete floor for post-anchor bolts or the steel beams for the steel structure as the hanging parts, a large number of holes or welding connection points seriously affect the structural safety. At the same time, once the large light box is installed, it is extremely difficult to adjust the lighting, replace the lamps, and maintain it.

[0057] Large light boxes use C-shaped hangers, and welded cylindrical vertical components to form connectors connected to the bottom of the transfer layer, reducing the number of openings, hanging a wheel, and openings on the wheel, which can hang multiple hangers, increasing the safety of the light box base connection. Multiple openings can be easily adjusted in size, with a larger tolerance for deviations, making construction more convenient.

[0058] Two pendants are set on the wheel, which can be used as temporary fixing measures to temporarily hang the entire light box on the base structure for easy installation and adjustment.

[0059] The top box plate of the large light box is connected between the clamping ring plates. In this embodiment, the top box plate of the large light box is a double-layer structure, and the two holding ring plates of the second layer clamp the second top box plate of the large light box. The double-layer top box plate not only increases the structural safety of the large light box, but also increases the maintenance cavity, which is convenient for later maintenance, lamp replacement, and shadowless adjustment.

[0060] The multi-layer clamping ring plate effectively ensures the safety and stability of the large light box. The number of clamping ring plates can be increased or decreased according to the working conditions. The clamping ring plates are connected by adjustable suspension rods, and there are nuts on the upper and lower parts of the suspension rods as adjustment and locking structures.

[0061] The inner ring hole position of the clamping ring plate of the top box board of large and small light boxes is used to install downlights or other lamps to supplement the brightness of the light box and achieve a shadowless effect. Downlights can be directly moved up and down on the multi-layer clamping ring plate, which is convenient for lamp replacement and height adjustment. Using Kirchhoff's integral theorem and light intensity theory, combined with field tests, the optimal vertical distance between the light source arrangement and the ceiling can be obtained to avoid the phenomenon of uneven light intensity caused by the light source being too far or too close, and achieve a shadowless light box effect.

[0062] A light trough is arranged on the second-layer top box board of the large light box. The light trough is a soft structure, and the LED light strip passes through the light trough to facilitate the later replacement of the light strip.

[0063] A slide rail is set on the top box board of the second layer, and a small lightweight flat plate can pass on the slide rail, which is convenient for later maintenance personnel to enter and move in the light box, thereby improving maintenance efficiency.

[0064] The transfer layer is a steel structure. A special C-shaped hanger is hung on the lower flange of the I-beam beam of the transfer layer to avoid stress changes caused by direct welding on the main structure. The C-shaped hanger is used to install the steel structure transfer layer. An adjustable hanger is installed under the transfer layer. The adjustable hanger fixes the surface material and the base structure of the light box to complete the installation of the entire ceiling and light box.

[0065] The super-large special-shaped curved ceiling structure of the present invention forms a step-down effect through multiple layers of special-shaped panels, and uses caulking round tubes to close the ends of two adjacent layers of special-shaped panels. The caulking round tubes can be rotatably adjusted to make the deformation at the closing easy to adjust. A circle is set along the outer edge of the special-shaped panel to form a pool top, and the pool top is used to install a large light box. The large light box is installed using a wheel and a clamping ring plate, which is convenient for installation and disassembly on the one hand, and convenient for later maintenance on the other hand.

[0066] It provides a new way of thinking for the optimisation items encountered in the design and construction of extra-large special-shaped ceilings and light boxes, and opens up new directions for the development of new technology applications.

[0067] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
