[0016] A construction method for a modularly assembled artistic ceiling system comprises the following steps: S1, install the required number of hangers on the wall structure according to the total weight of the entire ceiling system; S2, assembling the required number of transfer layer units, hoisting each transfer layer unit into the air one by one and connecting it to the hanger at its installation location to assemble it into a suspended ceiling transfer layer; S3, assembling multiple skeleton base molds, assembling the multiple skeleton base molds together; S4, installing a skeleton stem frame on each skeleton base mold; S5, covering the outer sides of all the skeleton bottom molds with a thin plate to wrap all the skeleton bottom molds and the connection seams between the skeleton bottom molds and the skeleton stem frame from all sides, thereby forming a skeleton outer frame outside the skeleton bottom molds and the skeleton stem frame; S6, installing a leveling frame on each skeleton stem frame, and installing an LED driver on the leveling frame to form a unitized decorative tire mold; S7, hoisting the unitized decorative tire mold until its leveling frame contacts one of the conversion layer units, and fixing the two with fasteners; S8, repeating steps S3-S7, fixing a unitized decorative tire mold at the bottom of each conversion layer unit; S9, installing a plurality of artistic light films on the bottom surface of each skeleton bottom mold of each unitized decorative tire mold, radiating from the center to the periphery, so that the bottom surface of the unitized decorative tire mold forms an entire inclined curved light film with the center concave upward and the periphery expanding outward; S10, embedding a teardrop-shaped molding frame in the gap between two adjacent unitized decorative tire molds; S11, uniformly installing light strips in the light troughs of all the skeleton stem frames, and electrically connecting each light strip to its corresponding LED driver.

[0017] Preferably, in step S1, the specific steps of installing the required number of hangers on the wall structure are: First, perform a stress analysis based on the total weight of the ceiling system to determine the number and location of hanging points; Then, the entire ceiling conversion layer is modularly divided into a plurality of conversion layer units according to the area of ​​the ceiling decoration layer, and the installation position of each conversion layer unit is determined; Then, according to the determined hanging point positions, reinforced purlins are added at the locations where hangers are required but there are no structural purlins; Finally, a hanger is fixed at each hanging point using a connecting angle code, with one part of the hanger fixed to the structural purlin and the other part fixed to the reinforced purlin.

[0018] Preferably, in step S2, when installing each conversion layer unit, each time a conversion layer unit is installed, a second connecting rod is installed on the vacant installation positions of all the disk nodes located on the four sides of the conversion layer unit. The second connecting rod is used to connect the currently installed conversion layer unit with the next conversion layer unit.

[0019] Preferably, in step S3, the specific steps of assembling a single skeleton base mold are: First, the bottom mold frame is CNC-machined based on the BIM model of the unitized decorative surface layer; Then, use square steel to build an internal bottom mold frame that matches the shape and size of the bottom mold frame. The internal bottom mold frame is formed with multiple vertical frame surfaces. The internal bottom mold frame is placed in the bottom mold frame and fixed to the bottom mold frame with fasteners. Then, a frame support plate that matches the frame shape and size at its position is fixed on each vertical frame surface of the bottom mold internal frame. When all the frame support plates are installed, the bottom and top surfaces formed by the bottom mold internal frame and multiple frame support plates are both expanded inclined curved surfaces.

[0020] Preferably, in step S4, the specific steps of installing the skeleton stem frame on the single skeleton base mold are: First, install the inner and outer panels vertically on the inner and outer sides of the skeleton bottom formwork respectively; Then, fix the connecting side panels to the left and right sides of the skeleton bottom mold, and connect the two ends of the connecting side panels to the inner and outer side panels; Then, a plurality of radially distributed arc-shaped stems are connected between the inner side panel and the outer side panel, and arc-shaped support plates are respectively fixed on the inner walls of the left and right connecting side panels.

[0021] Preferably, in step S9, the specific steps of installing a plurality of artistic light films radiating from the center to the periphery on the bottom surface of a single skeleton bottom mold are: First, prepare two fireproof and light-transmitting films. According to the design layout of the ice crackle pattern, engrave the same pattern of grouting grooves on one of the fireproof and light-transmitting films, and engrave the same pattern of texture protrusions on the other fireproof and light-transmitting films. Then, a UV printer is used to print ice crackle silk patterns on the grouting groove and the texture protrusions respectively using UV paint, and the UV light source is fully irradiated to fully cure the UV paint between the two layers of fireproof and light-transmitting films. The two pieces of fireproof and light-transmitting films are then glued together so that the texture protrusions are embedded in the grouting groove to obtain an artistic light film. Then, follow the above steps to make the various artistic light films required for the bottom surface of the skeleton bottom mold; Then, the art lamp film is brought into contact with the bottom edge of the frame support plate at its installation position, and the art lamp film is fixed to the internal frame of the bottom mold or the internal frame of the bottom mold and the outer frame of the bottom mold using metal connectors.

[0022] The beneficial effects of the present invention are: The present invention divides the entire ceiling conversion layer into multiple conversion layer units according to the size of the area, and performs independent production, assembly, hoisting and installation, and also divides the decorative surface layer into the same number of unitized decorative surface layers for independent production, assembly, hoisting and installation. Through modular construction and hoisting, an effective combination of prefabricated construction and personalized ceiling requirements is achieved, which not only reduces the construction difficulty and construction risk of the entire ceiling system, but also increases construction efficiency and construction quality. At the same time, the single unitized decorative surface layer of the present application is in the shape of a lotus, which is beautiful and unique in shape, breaking through the single shape limitation of traditional ceilings, greatly enhancing the artistic sense and visual effect of the interior space, achieving a unique design effect, and meeting personalized decoration needs. At the same time, it can also cover up the shortcomings of the building structure, improve the space proportion, make the space more harmonious and unified, and add a sense of hierarchy to the interior space, making the entire space richer and more three-dimensional.

[0023] Each unitized decorative surface layer of the present invention is composed of multiple skeleton bottom molds, skeleton stem frames, and leveling frames. The skeleton bottom molds can not only support and fix the skeleton stem frames, but also can be used to lay and fix artistic light films to form a lotus-shaped light film shape on its lower surface with the center upwardly concave and the surrounding areas expanding outward. The light strips can be hidden and installed on the skeleton stem frames to avoid leakage of the light strips and affecting the appearance. The leveling frame on the skeleton stem frame is used to achieve a stable connection between the entire unitized decorative surface layer and the ceiling conversion layer, thereby ensuring the stability of the connection of the unitized decorative surface layer.

[0024] The bottom of each unitized decorative surface layer of the present invention forms a lotus-shaped lamp film shape with a central upward depression and outward expansion on all sides, and the hole in the middle depression reveals a convex eaves fixed on the upper edge of the skeleton stem frame. The convex eaves can not only cover the main roof wall structure exposed in the middle depression, but also add a sense of layering to the interior space, making the entire space richer and more three-dimensional.

[0025] The present invention installs a teardrop-shaped modeling frame in the gap between two adjacent unitized decorative surface layers, which can connect the unitized decorative surface layers into one, improve the integrity and deformation resistance of the components of the entire decorative surface layer, improve the structural stability of the entire decorative surface layer, and also increase the artistic sense of the entire ceiling.

[0026] The skeleton base mold of the present invention is vertically provided with a plurality of skeleton support plates, which can not only effectively support the stems in the skeleton stem frame to prevent the stems from deformation, but also provide multi-point linear contact support for each piece of art light film, so as to avoid problems such as installation wrinkles and black spots on the art light film, which affect the appearance.

[0027] The internal ice crackle filament pattern of the artistic lamp film of the present invention gradually becomes lighter from the inside to the outside, and the texture density of the ice crackle filament pattern gradually decreases from the inside to the outside, which can greatly increase the artistic beauty of the entire decorative layer while meeting the lighting needs.

[0028] The present invention divides the ceiling conversion layer into multiple conversion layer units, and sequentially hangs and fixes the conversion layer units assembled on the ground on the roof steel structure through hangers to assemble a whole ceiling conversion layer. This not only does not affect the stress of the roof steel structure, but also reduces the difficulty of installing and constructing the ceiling conversion layer, avoids high-altitude welding operations, and the entire operation process only requires assembly. At the same time, the installation error can be adjusted in real time through its disc node during the installation process, effectively improving the installation accuracy of the ceiling conversion layer.

[0029] The conversion layer unit of the present invention uses a disk node to connect the connecting rods (first connecting rod and second connecting rod) of the conversion layer. The disk node can not only fine-tune the size and positioning position of a single conversion layer unit, but also fine-tune the spacing between connected conversion layer units. At the same time, the disk node can also fine-tune the plane angle of the conversion layer unit to ensure its installation accuracy.

[0030] This application increases the structural strength of the roof steel structure and enhances its load-bearing capacity by adding reinforced purlins between the structural purlins of the roof steel structure on the basis of meeting the arrangement of the hanging points, thereby ensuring the stability of the installation of the suspended top layer.

[0056] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0057] The present invention provides a modularly assembled artistic ceiling system, including a ceiling conversion layer and a decorative surface layer. The ceiling conversion layer is composed of a plurality of conversion layer units 8, each of which is fixed to the main wall structure through a plurality of hangers. The decorative surface layer is composed of a plurality of unitized decorative surface layers, and a corresponding unitized decorative surface layer is fixed to the bottom of each conversion layer unit 8 through fasteners.

[0058] Specifically, if Figure 15 、 18 As shown, the plurality of conversion layer units of the suspended ceiling conversion layer are arranged in a matrix, and two adjacent conversion layer units 8 are connected via a second connecting rod 85 .

[0059] like Figure 16 As shown, each conversion layer unit 8 includes a plurality of disk nodes 9 distributed in a matrix, and a plurality of first connecting rods 81 connected between two adjacent disk nodes 9 .

[0060] like Figure 17As shown, each disc node 9 includes two upper and lower adjustable discs 91, and a first hanger fixing hole 92 for connecting the hanger on the reinforcing purlin 82 is provided in the center of the adjustable disc 91. Four waist-shaped connecting rod fixing holes 93 uniformly distributed in the circumferential direction are provided on the adjustable disc 91 along its radial direction, and a group of decorative layer fixing holes 94 for directly fixing the leveling frame 3 to the bottom of the conversion layer unit is provided between two adjacent connecting rod fixing holes 93. The four connecting rod fixing holes of the upper and lower adjustable discs 91 are aligned up and down to form four installation positions for fixing the first connecting rod 81.

[0061] Second hanger fixing holes 84 for connecting to the hangers on the structural purlins 83 are formed on some of the first connecting rods of the conversion layer unit 8 .

[0062] In this embodiment, each conversion layer unit includes 9 disk nodes, which are distributed in a matrix. A first connecting rod 81 is connected between two adjacent disk nodes 9, thereby forming a square conversion layer unit. The hanging points of the square conversion layer unit are set on the disk nodes at its four corners and a part of the first connecting rod.

[0063] In this embodiment, the reinforcing purlins are located directly above the four corners of the conversion layer unit.

[0064] A unitized decorative surface layer is correspondingly fixed to the bottom of each conversion layer unit 8 .

[0065] like Figure 1-4 As shown, each unitized decorative surface layer includes a skeleton base mold 1, a skeleton stem frame 2, a leveling frame 3, a skeleton outer frame 4, a teardrop-shaped molding frame 6 and an artistic light film 5. There are multiple skeleton base molds 1, and the multiple skeleton base molds 1 are symmetrically spliced. Multiple artistic light films 5 are fixed on the bottom surface of each skeleton base mold 1. The multiple artistic light films 5 on each skeleton base mold 1 are radiated from the inside to the surrounding areas (the "inside" refers to the side close to the center of the unitized decorative surface layer). A skeleton stem frame 2 is stacked and fixed on the top of each skeleton base mold 1, and a leveling frame 3 is fixed on each skeleton stem frame 2. The leveling frame 3 is fixed to the decorative layer fixing hole 94 at the corresponding position on the corresponding conversion layer unit through fasteners such as bolts.

[0066] The skeleton outer frame 4 wraps all the skeleton bottom molds 1 and the skeleton stem frame 2 from all sides, and the teardrop-shaped modeling frame 6 is embedded in the gap between two adjacent unitized decorative surface layers and is fixed to the skeleton outer frames 4 of the unitized decorative surface layers on both sides thereof through fasteners.

[0067] Specifically, each skeleton base mold 1 includes a base mold outer frame 11, a base mold internal skeleton 12 and a skeleton support plate 13. The base mold internal skeleton 12 is arranged in the base mold outer frame 11. The outer contour of the base mold internal skeleton 12 is the same as the contour of the base mold outer frame 11. A plurality of vertical skeleton surfaces are formed on the base mold internal skeleton 12. A skeleton support plate 13 that matches the skeleton shape and size at its position is fixed on each vertical skeleton surface. The bottom surface and top surface formed by the skeleton of the base mold internal skeleton 12 and the plurality of skeleton support plates 13 are both expanded inclined curved surfaces.

[0068] In this embodiment, the curvature of the bottom surface formed by the bottom mold internal frame 12 and the plurality of frame support plates 13 is smaller than the curvature of the top surface formed by the bottom mold internal frame 12 and the plurality of frame support plates 13 .

[0069] like Figure 6 、 7 As shown, the bottom mold outer frame 11 is an irregular aluminum film frame, and all the bottom and top frames of the frame are curved fan-shaped. The outer frame shape and size of the bottom mold internal skeleton 12 are the same as the shape and size of the bottom mold outer frame 11, but the outer frame of the bottom mold internal skeleton 12 is also connected to a plurality of connecting skeletons. The upper and lower corresponding connecting skeletons at the same position constitute a vertical skeleton surface, and a skeleton support plate 13 is fixed on each vertical skeleton surface. The top support surface formed by all the skeleton support plates 13 (that is, the top surface formed by the skeleton of the bottom mold internal skeleton 12 and the plurality of skeleton support plates 13) can effectively support the various stems 24 of the skeleton stem frame 2, and the bottom support surface (that is, the bottom surface formed by the skeleton of the bottom mold internal skeleton 12 and the plurality of skeleton support plates 13) can effectively support the artistic lamp film 5 to avoid problems such as installation wrinkles of the lamp film.

[0070] The artistic light film 5 is fixed to the bottom mold internal frame 12 or the bottom mold internal frame 12 and the bottom mold outer frame 11 through a metal connector (such as an L-shaped metal connector).

[0071] in, Figure 6 The structure of the bottom mold internal skeleton 12 in the skeleton bottom mold 1 is similar to Figure 7 The structure of the bottom mold internal skeleton 12 is slightly different. Figure 6 The bottom mold internal frame 12 only includes longitudinal vertical frame surfaces and the vertical frame surfaces are arranged parallel to each other; Figure 7 The bottom mold internal frame 12 includes not only longitudinal vertical frame surfaces, but also transverse vertical frame surfaces, and the vertical frame surfaces are distributed radially.

[0072] Each art film 5 installed on the bottom of the skeleton base mold 1 has a different shape, but all have four edges: an inner edge, an outer edge, a left edge, and a right edge. The inner and outer edges of each art film are curved, while the left and right edges are straight. The left and right edges are not parallel, forming a certain angle between them. In other words, the width of each art film gradually increases along its length, and its inner and outer edges are curved.

[0073] like Figure 12 As shown, each artistic light film 5 has an ice crackle pattern formed inside. In this embodiment, the ice crackle pattern of the artistic light film 5 gradually becomes shallower from the inside out, and the texture density of the ice crackle pattern gradually decreases from the inside out. In this embodiment, the film of the artistic light film 5 is made of acrylic.

[0074] The skeleton stem frame 2 is stacked and fixed on the skeleton bottom mold 1, as shown in FIG. Figure 8 、 9 As shown, the skeleton stem frame 2 includes an inner panel 21, an outer panel 22 located obliquely below the inner panel 21, and a connecting side panel 23 connecting the two ends of the inner panel 21 and the outer panel 22 respectively.

[0075] The inner panel 21 and the outer panel 22 are both irregular curved panels placed vertically, and the connecting side panel 23 is an arc panel that is tilted downward to connect the inner panel 21 and the outer panel 22. The inner panel 21, the outer panel 22 and the left and right connecting side panels 23 form a curved fan-shaped frame.

[0076] Support plates 25 for supporting the leveling frame 3 are fixed on the inner walls of the left and right connecting side plates 23. When installing the leveling frame 3, the leveling frame is placed on the left and right support plates 25 to fix the leveling frame 3 and the skeleton stem frame 2 as a whole.

[0077] A plurality of radially distributed stems 24 are connected between the inner side panel 21 and the outer side panel 22. The two support plates 25 and the plurality of stems 24 form an expanding inclined surface. Figure 10 As shown, the stem 24 has a first light trough 26 formed along its length for accommodating a light strip. Second light troughs 27 are also formed on the outer side of the outer panel 22 and the outer side of the connecting side panel 23 for accommodating the light strip. The light strips in the first and second light troughs 26 and 27 are both controlled by an LED driver mounted on the leveling frame 3. In this embodiment, the light strips in the light troughs can be configured as upward-facing lights.

[0078] In this embodiment, each stem 24 is composed of two symmetrical L-shaped curved plates, and a curved first lamp trough 26 is formed between the two L-shaped curved plates; the support plate 25 is also an L-shaped curved plate, and its horizontal plate surface is vertically fixed to the connecting side plate 23, and its vertical plate surface is parallel to the plate surface of the connecting side plate 23. A groove for accommodating the leveling pillar 32 of the leveling frame 3 can be formed between the vertical plate surface of the support plate 25 and the plate surface of the connecting side plate 23, and the leveling pillar 32 can be vertically supported and fixed on the horizontal plate surface of the support plate 25.

[0079] In a preferred embodiment, a convex eave 7 extends horizontally inward on the side surface of the inner side panel 21 facing the central symmetrical point, and a light-transmitting plate 71 is embedded on the lower surface of the convex eave 7.

[0080] like Figure 11 As shown, the leveling frame 3 includes a horizontal steel frame 31 that matches the outer contour of the skeleton stem frame 2, and multiple leveling struts 32 fixed to both sides of the bottom of the horizontal steel frame 31. The lengths of the multiple leveling struts on the same side gradually increase from the inside to the outside. An LED driver for controlling the light strip is provided above the horizontal steel frame 31. The horizontal steel frame 31 is provided with multiple bolt holes for fixing the transition layer unit. During installation, the bolt holes on the horizontal steel frame 31 should be aligned with the decorative layer fixing holes 94 on the disk nodes of the corresponding transition layer unit 8, and the upper surface of the horizontal steel frame 31 should be in contact with the lower surface of the transition layer unit 8. Bolts should then be inserted through the decorative layer fixing holes 94 and the bolt holes on the horizontal steel frame 31 at the same time. The nuts should then be tightened on the bolts to secure the leveling frame 3 to the transition layer unit 8, thereby fixing the unitized decorative surface layer to the bottom of the transition layer unit 8.

[0081] The teardrop-shaped frame 6 is embedded in the gap between two adjacent unitized decorative surface layers and fixed to the skeleton outer frames 4 of the unitized decorative surface layers on both sides thereof by fasteners. In this embodiment, the teardrop-shaped frame 6 is integrally injection-molded by a hot pressing process.

[0082] like Figure 3As shown, in this embodiment, the unitized decorative surface layer is composed of four skeleton base molds 1, each of which is stacked and fixed with a skeleton stem frame 2, and each skeleton stem frame 2 is fixed with a leveling frame 3. After the four skeleton base molds 1 are symmetrically spliced ​​and the skeleton stem frames 2 and leveling frames 3 are installed on them, the entire bottom surface of the unitized decorative surface layer is an inclined curved surface with a center that is upwardly concave and the periphery that expands outward, similar to the shape of a lotus or a shallow bowl. A plurality of artistic light films are fixed to this ground surface, radiating from the center of the bottom surface to the periphery. If the entire unitized decorative surface layer is viewed from the bottom up, the center of its entire bottom surface forms a regular polygonal hole, each side of which is an arc. Since each skeleton stem frame 2 has a convex eave 7 extending inward from the upper edge, when viewing the entire unitized decorative surface layer from the bottom up, the convex eave 7 located within the regular polygonal hole can be seen. The edges of the four convex eaves 7 also form a quadrilateral hole, each side of which is also an arc.

[0083] In this embodiment, one unitized decorative surface layer is equipped with one LED driver. For a single unitized decorative surface layer, the LED driver thereon can be installed on the top of any leveling frame 3 thereon; the light strips on each unitized decorative surface layer can be independently controlled by their respective equipped LED drivers.

[0084] The present invention also provides a construction method of a modularly assembled artistic ceiling system, which specifically includes the following steps: S1, install the required number of hangers on the wall structure according to the total weight of the entire ceiling system.

[0085] Specifically, first, a force analysis is performed based on the total weight of the ceiling system to determine the number and location of the hanging points. The hanging points of the entire ceiling system are distributed in a matrix, and a hanging rod is required at each hanging point. Then, the entire ceiling conversion layer is modularly divided into a plurality of conversion layer units according to the size of the ceiling conversion layer, and the installation position of each conversion layer unit is determined. In this embodiment, the structure of each conversion layer unit 8 is as described above; Then, according to the determined hanging point positions, reinforced purlins are added at the locations where hangers are required but there are no structural purlins; Finally, according to the determined hanging point position, a connecting angle code 95 is fixed on the structural purlin 83 and the reinforcing purlin 82 at the corresponding position. The connecting angle code 95 is a galvanized angle code with a fixing circular hole. Then, a hanger rod 10 is threadedly fixed on each connecting angle code 95. The hanger rod 10 is used to fix the transition layer unit.

[0086] S2, assembling the required number of conversion layer units 8, hoisting each conversion layer unit into the air one by one and connecting them to the suspension rods at their installation positions, and assembling them into a suspended ceiling conversion layer.

[0087] When installing the conversion layer unit 8, the conversion layer unit 8 is lifted up to its installation position, and the first hanger fixing holes 92 of the disc nodes on the four corners are aligned with the hangers on the reinforcing purlin 82 at their positions, and the second hanger fixing holes 84 on the first connecting rod 81 are aligned with the hangers on the structural purlin 83. Then, the conversion layer unit is continued to be moved upward, so that the hangers on the reinforcing purlin 82 pass through the first hanger fixing holes 92, and the hangers on the structural purlin 83 pass through the second hanger fixing holes 84, and then the nuts are tightened on each hanger 10 to lock and fix them.

[0088] When installing the conversion layer unit 8, if a local installation error occurs, the installation deviation can be corrected by adjusting the fastening position of the fasteners on the connecting rod fixing holes 93 of the disk nodes near the error location or adjusting the angle between the first connecting rods on the disk nodes. For example, if the centers of the disk nodes at the two left corners of the conversion layer unit cannot be aligned with the suspension rods at that location, the fastening positions of the fasteners used to fasten the transverse first connecting rods on the three disk nodes on the left side can be moved, that is, the installation alignment deviation can be adjusted by increasing or adjusting the width of the two squares on the left column of the conversion layer unit. At the same time, if only the center of the disk node at the upper left corner of the conversion layer unit cannot be aligned with the suspension rod at that location, the installation deviation can be corrected by adjusting the angle between the two first connecting rods connected to the disk node, that is, adjusting the square at the upper left corner of the conversion layer unit to an irregular quadrilateral to adjust the installation alignment deviation.

[0089] Preferably, each time a conversion layer unit 8 is installed, a second connecting rod 85 is installed on the vacant installation positions of all the disk nodes on the four sides of the conversion layer unit 8. The second connecting rod 85 is used to connect the currently installed conversion layer unit with the next conversion layer unit.

[0090] In this embodiment, the reinforcing purlins are located directly above the four corners of the conversion layer unit.

[0091] S3, assembling multiple skeleton bottom molds 1, and assembling multiple skeleton bottom molds 1 together.

[0092] Specifically, first, a bottom mold frame 11 is numerically processed according to the BIM model of the unitized decorative surface layer; Then, a bottom mold internal frame 12 is constructed using square steel to match the shape and size of the bottom mold frame 11. The bottom mold internal frame 12 is formed with multiple vertical frame surfaces. The bottom mold internal frame 12 is placed inside the bottom mold frame 11 and fixed to the bottom mold frame 11 using fasteners. Then, bolts are used to fix a frame support plate 13 that matches the frame shape and size at its position on each vertical frame surface of the bottom mold internal frame 12. When all the frame support plates 13 are installed, the bottom and top surfaces formed by the bottom mold internal frame 12 and multiple frame support plates 13 are both expanded inclined curved surfaces, where the curvature of the bottom surface is smaller than the curvature of the top surface.

[0093] S4, a skeleton stem frame 2 is installed on each skeleton base mold 1.

[0094] Specifically, first, the inner panel 21 and the outer panel 22 are vertically installed on the inner and outer sides of the skeleton bottom mold 1 respectively; Then, fix the connecting side panels 23 to the left and right sides of the skeleton bottom mold 1, and connect the two ends of the connecting side panels 23 to the inner side panels 21 and the outer side panels 22; Then, a plurality of radially distributed arc-shaped stems 24 are connected between the inner side panel 21 and the outer side panel 22 , and arc-shaped support plates 25 are fixed on the inner walls of the left and right connecting side panels 23 , respectively.

[0095] S5, a thin plate is coated on the outside of all the skeleton bottom molds 1 to wrap all the skeleton bottom molds 1 and the connection seams between the skeleton bottom molds 1 and the skeleton stem frame 2 from all sides, thereby forming a skeleton outer frame 4 on the outside of the skeleton bottom molds 1 and the skeleton stem frame 2.

[0096] S6, a leveling frame 3 is installed on each skeleton stem frame 2, and an LED driver is installed on the leveling frame 3 to form a unitized decorative tire mold.

[0097] In this embodiment, one LED driver is correspondingly installed on one unitized decorative tire mold, and the LED driver can be optionally installed on the top of one of the leveling frames 3 of the unitized decorative tire mold.

[0098] S7, the unitized decorative tire mold is hoisted until its leveling frame 3 contacts one of the conversion layer units, and the two are fixed by fasteners.

[0099] S8, repeating steps S3-S7, and fixing a unitized decorative tire mold at the bottom of each conversion layer unit.

[0100] S9, a plurality of artistic light films 5 radiating from the center to the surrounding are installed on the bottom surface of each skeleton bottom mold 1 of each unitized decorative mold, so that the bottom surface of the unitized decorative mold forms an entire inclined curved light film with the center concave upward and the surroundings expanding outward.

[0101] Specifically, first, prepare two fireproof and light-transmitting films, and engrave the same pattern of ice crackle silk pattern on one of the fireproof and light-transmitting films, and engrave the same pattern of texture protrusions on the other fireproof and light-transmitting films; Then, a UV printer is used to print ice crackle silk patterns on the grouting groove and the texture protrusions respectively using UV paint, and a UV light source is used to fully irradiate the UV paint between the two layers of fireproof and light-transmitting films to completely cure them. The two layers of fireproof and light-transmitting films are then glued together so that the texture protrusions are embedded in the grouting grooves to obtain an artistic light film 5. Then, all the artistic light films 5 required for the bottom surface of each skeleton bottom mold 1 are produced in sequence according to the above steps; Then, the art lamp film 5 is brought into contact with the bottom edge of the frame support plate 13 at its installation position, and the art lamp film 5 is fixed to the bottom mold internal frame 12 or the bottom mold internal frame 12 and the bottom mold outer frame 11 using metal connectors.
