[0031] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. 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 panel 2, and a large light box 3.

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

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

[0036] Specifically, a layer of profiled panels 21 is installed at the bottom of the multi-layered styling steps 11 and the bottom of the transition level 1. The profiled panels 21 are arranged at an angle. A closing seam is formed between the upper portion of one profiled panel 21 and the lower portion of the upper profiled panel 21. A caulking tube 22 is embedded in the closing seam. Both ends of the caulking tube 22 are rotatably mounted to the styling steps 11 via hinged arms 23. The styling steps 11 are equipped with locking members 24 for locking the hinged arms 23.

[0037] The large light box 3 and the bottom of the conversion layer 1 are connected with a wheel disc 31. 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 on the outside of 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. The top box plate is provided with a through hole connected to the inner ring holes of the two clamping ring plates 33. 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 shaped step 11. The other end of the articulated arm 23 is connected to an inner lining plate 25. This inner lining plate 25 is curved, its curvature matching the curvature of the wall of the caulking tube 22. The inner lining plate 25 extends into the end of the caulking tube 22 and presses against the inner wall of the caulking tube 22. The other end of the articulated arm 23 is connected to a fastening plate 26. This fastening plate 26 presses against the outer wall of the caulking tube 22. The position of the fastening plate 26 corresponds to that 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 holes. One end of the support column is pressed against the outer wall of the caulking circular tube 22.

[0040] The other end of the hinge arm 23 is provided with a plurality of lock holes, which are spaced apart along the circumferential direction of the hinge arm 23. The locking member 24 is detachably mounted on the molding step 11 and inserted into a lock 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 external threads. Two first screw members are screwed onto the upper end of the suspension rod 32. The two first screw members are clamped to the wheel disc 31. Two second screw members are screwed onto the lower end of the suspension rod 32. The two second screw members are clamped to the clamping ring plate 33 outside the large light box 3.

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

[0044] The present invention provides a construction method for 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 installed at the bottom of the multi-layer shaping step 11 and the bottom of the conversion layer 1, respectively, 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. Rotate the hinged arm 23 to embed the caulking tube 22 in the closing seam.

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

[0050] The laminated ceiling panels of the ultra-large, special-shaped curved ceiling structure of this invention have varying degrees of retraction, creating a stepped effect. Each step is formed using caulking tubes as the interface. The caulking tubes are long, approximately 13 meters long and 20 cm in diameter, making them heavy. Using external clamps would affect the overall appearance and fail to meet design requirements. Using conventional hangers for installation would require holes installed at regular intervals, damaging the caulking tubes. Furthermore, the hangers would clash with the metal surface, requiring constant adjustment of the hanger position. This makes it difficult to maintain the caulking tube angle and inconvenient to adjust.

[0051] The caulking tube is pivotally mounted on the styling steps of the transfer level using an articulated arm. An inner lining plate with the same curvature as the caulking tube is mounted on the articulated arm. Both ends of the caulking tube are overlapped on the inner lining plate. The inner lining plate can be directly welded in place or made adjustable, depending on the installation requirements.

[0052] There are two lifting holes on the inner lining plate for temporary installation and removal of caulking round pipes. After the positioning is determined in the later stage, there is no need to dismantle 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 reinforcement 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. The fastening plate has a hole 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 supports the roundness of the caulking round tube.

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

[0056] Large light boxes are heavy. Whether drilling holes in the concrete floor for post-installed anchor bolts or attaching components to steel beams, the numerous holes and welded connections seriously compromise structural safety. Furthermore, once a large light box is installed, subsequent lighting adjustments, fixture replacements, and maintenance are extremely difficult.

[0057] Large light boxes utilize C-shaped hangers, welded cylindrical vertical members to form connectors connected to the base of the transfer layer, reducing the number of openings. A rotary disc with holes allows for multiple hangers to be attached, increasing the security of the light box's base connection. Multiple openings allow for easy size adjustment, greater tolerance for deviation, and more convenient construction.

[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 panel of the large light box is connected between the clamping ring plates. In this embodiment, the top panel of the large light box has a double-layer structure, with two retaining ring plates on the second layer clamping the second top panel of the large light box. This double-layer top panel not only increases the structural safety of the large light box, but also provides an additional inspection cavity, facilitating 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 hangers, and there are nuts on the upper and lower parts of the hangers as adjustment and locking structures.

[0061] The inner ring holes of the clamping rings on the top panels of both large and small light boxes are used to install downlights or other lighting fixtures, supplementing the light box's brightness and achieving a shadowless effect. Downlights can be moved directly up and down within the multi-layer clamping rings, facilitating fixture replacement and height adjustment. Using Kirchhoff's integral theorem and light intensity theory, combined with field testing, the optimal vertical distance between the light source and the ceiling is determined to avoid uneven light intensity caused by light sources that are too far or too close, achieving a shadowless 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 installed on the top box board of the second layer, and a small lightweight flat panel can pass on the slide rail, which makes it 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. Special C-shaped hangers are suspended from the lower flanges of the I-beams to prevent stress changes caused by direct welding on the main structure. The C-shaped hangers are installed in the steel transfer layer. Adjustable hangers are installed below the transfer layer to secure the surface material and the light box base structure, completing the entire ceiling and light box installation.

[0065] The ultra-large, irregularly shaped curved ceiling structure of this invention uses multiple layers of irregularly shaped panels to create a stepped effect. Caulking tubes are used to close the gaps between adjacent layers of irregularly shaped panels. The caulking tubes can be rotated and adjusted, making deformation at the gaps easily adjustable. A ring of irregularly shaped panels is provided along the outer edge of the transition layer to form the pool roof, which is used to mount a large light box. The light box is mounted using a wheel and clamping ring, facilitating installation and removal, as well as subsequent maintenance.

[0066] It provides a new approach to the optimization issues encountered in the design and construction of oversized special-shaped ceilings and light boxes, and opens up new directions for the development of new technology applications.

[0067] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features having similar functions disclosed in this application.
