[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] like Figures 1 to 13As shown, this application provides an outdoor-suitable prefabricated grid ceiling system for outdoor decoration. The outdoor-suitable prefabricated grid ceiling system includes a grid structure 10, a beam structure 20, a hanger structure 30, a bracing structure 40, a first adapter 50, a second adapter 60, and a third adapter 70. One end of the hanger structure 30 is fixedly connected to the roof 100 via the first adapter 50, and one end of the bracing structure 40 is fixedly connected to the roof 100 via the second adapter 60. The first adapter 50 and the second adapter 60 are spaced apart. The other end of the bracing structure 40 is connected to the end of the hanger structure 30 away from the first adapter 50. The other end of the hanger structure 30 is connected to the beam structure 20 via the third adapter 70. The grid structure 10 is connected to the beam structure 20 or the third adapter 70 away from the hanger structure 30. At one end, the modular structure allows for detachable connection of the grid structure 10, beam structure 20, hanger structure 30, diagonal brace structure 40, first adapter 50, second adapter 60, and third adapter 70, enabling rapid assembly and disassembly of the grid ceiling system and reducing construction difficulty. Furthermore, the grid structure 10, beam structure 20, hanger structure 30, diagonal brace structure 40, first adapter 50, second adapter 60, and third adapter 70 are all independent prefabricated components, allowing for partial replacement when damaged and reuse in other projects after disassembly, aligning with green construction principles. Additionally, this application facilitates the installation of outdoor grid ceiling systems and enhances their wind pressure resistance, meeting the wind pressure requirements for outdoor grid ceiling systems.

[0042] In one optional embodiment, the beam structure 20 has beam openings 21 spaced apart along its length, the hanger structure 30 has hanger openings 31 along its length, and the brace structure 40 has brace openings 41 along its length. The first adapter 50 and the second adapter 60 are fixedly connected to the roof 100 by mechanical anchors. One end of the hanger structure 30 is detachably connected to the first adapter 50 through the hanger opening 31. The brace structure 40 is detachably connected to the second adapter 60 through the brace opening 41, and the other end of the brace structure 40 is detachably connected to the hanger opening 31 through the brace opening 41. The hanger opening 31 is connected to the first adapter 50 through the second adapter 60. The three adapters 70 are detachably connected, the beam structure 20 is detachably connected to the third adapter 70, and the grid structure 10 is detachably connected to the beam opening 21. No welding is required. The original grid ceiling system with welded connection is replaced with a prefabricated grid ceiling system, which not only improves construction efficiency, simplifies the structure, and makes it easy to process and produce, but also saves construction costs. The grid structure 10, beam structure 20, hanger structure 30, diagonal brace structure 40, first adapter 50, second adapter 60 and third adapter 70 can all be reused, which solves the pain points of traditional grid ceiling systems such as low construction efficiency, poor wind resistance and non-recyclability.

[0043] In an optional embodiment, the first adapter 50 includes a first adapter body 51 and a first anchor bolt 52, and the second adapter 60 includes a second adapter body 61 and a second anchor bolt 62, so as to distribute the load through dual paths and avoid single-point stress concentration. The mechanical anchor bolts include a first anchor bolt 52 and a second anchor bolt 62. The first adapter body 51 is fixed to the roof 100 by the first anchor bolt 52, and the second adapter body 61 is fixed to the roof 100 by the second anchor bolt 62, ensuring that the load on the first adapter body 51 and the second adapter body 61 can be effectively transferred to the building structure.

[0044] In one optional embodiment, the spacing between two adjacent first adapters 50 is no greater than 1200mm, and the second adapter 60 is disposed between two adjacent first adapters 50, so that a high-density triangular grid can be formed between the diagonal bracing structure 40 and the suspension rod structure 30, ensuring that the wind pressure resistance of the outdoor prefabricated grid ceiling system can be effectively improved. That is, this application achieves precise control of structural performance while ensuring ease of assembly through the strict arrangement rules of the first adapters 50 and the second adapter 60.

[0045] In an optional implementation, the beam openings 21 on the beam structure 20, the hanger openings 31 on the hanger structure 30, and the brace openings 41 on the brace structure 40 are designed at equal intervals to allow the beam structure 20, hanger structure 30, and brace structure 40 to flexibly adjust their installation positions according to the installation scenario, thereby adapting to different spatial requirements. The beam openings 21, hanger openings 31, and brace openings 41 are bolted to the first adapter 50, the second adapter 60, and the third adapter 70, thereby enabling rapid assembly and disassembly of the outdoor-use prefabricated grid ceiling system and reducing its construction difficulty.

[0046] In an optional embodiment, the two ends of the bracing structure 40 are respectively connected to the second adapter 60 and the hanger structure 30 to form a rigid triangular support, so as to improve the overall resistance to lateral wind loads of the outdoor-applicable prefabricated grid ceiling system.

[0047] In one alternative implementation, the beam structure 20, the hanger structure 30, and the diagonal brace structure 40 are all made of light steel keel. Compared with wooden keel, light steel keel does not deform and is more low-carbon and environmentally friendly, which can reduce fire hazards both during construction and after delivery.

[0048] In an optional embodiment, the boom structure 30 includes a boom base plate 30a and a boom surround plate 30b formed by rolling or welding sheet metal. The boom surround plate 30b and the boom base plate 30a are formed on the periphery of the boom base plate 30a, and the boom opening 31 is formed at least on the boom base plate 30a and the boom surround plate 30b. The boom surround plate 30b extends vertically upward from the boom base plate 30a to form a sidewall, and together with the boom base plate 30a, forms a semi-enclosed structure, which can increase its moment of inertia by two to three times, thereby resisting lateral swaying caused by wind vibration.

[0049] Specifically, the suspension rod structure 30 can be made by cutting sheet metal and then bending it. Its production efficiency is extremely high and the cost is correspondingly low. Therefore, the production efficiency of the entire outdoor prefabricated grid ceiling system is greatly improved and the production cost is reduced at the same time. This allows the suspension rod structure 30 to achieve lightweight, high strength and rapid assembly through the combination of sheet metal forming and intelligent opening.

[0050] In one optional embodiment, the boom enclosure 30b includes a first boom enclosure 30b and a second boom enclosure 30b. The first boom enclosure 30b extends along the length of the boom base plate 30a and is disposed on both sides of the boom base plate 30a. The second boom enclosure 30b is connected to the two first boom enclosures 30b and is located at the end of the boom base plate 30a. The boom opening 31 includes a first boom opening 311, a second boom opening 312, and a third boom opening 313. The first boom opening 311 is formed on the boom base plate 30a, the second boom opening 312 is formed on the first boom enclosure plate 30b, and the third boom opening 313 is formed on the second boom enclosure plate 30b. The first mounting hole 513 on the first adapter 50 is detachably connected to the first boom opening 311 and the second boom opening 312 via adjusting bolts 80. The diagonal brace opening 41 is detachably connected to the first boom opening 311 via adjusting bolts 80, and the third adapter 70 is detachably connected to the third boom opening 313 via adjusting bolts 80.

[0051] In one alternative embodiment, the cross-section of the boom structure 30 is C-shaped, and the first adapter 50 is nested in the C-shaped opening of the boom structure 30, thereby achieving a combination of efficient force transmission and rapid assembly between the boom structure 30 and the first adapter 50.

[0052] In an optional embodiment, the hanger panel 30b includes at least a first side plate and a second side plate. The first side plate is arranged along the length direction of the hanger base plate 30a, and the second side plate is arranged along the length direction of the hanger base plate 30a. Through the coordinated force-bearing of the first side plate and the second side plate, the multi-directional load transfer of the hanger structure 30 is realized. Combined with the nested first adapter 50, the outdoor-applicable prefabricated grid ceiling system can have the characteristics of high strength, high precision and quick installation.

[0053] In one optional implementation, the structure of the beam structure 20 and the diagonal brace structure 40 may be the same as or different from the structure of the hanger structure 30. This maintains the uniformity between the beam structure 20, the diagonal brace structure 40 and the hanger structure 30 to ensure assembly coordination, while also allowing for differentiated design based on their respective stress characteristics to flexibly adapt to various installation scenarios.

[0054] In an optional embodiment, the bracing structure 40 includes a bracing base plate 40a and a bracing perimeter plate 40b formed by rolling or welding sheet metal. The bracing perimeter plate 40b extends along the length of the bracing base plate 40a and is disposed on one side of the bracing base plate 40a to enhance the bending stiffness of the bracing structure 40 and prevent buckling.

[0055] In an optional embodiment, the diagonal brace opening 41 includes a first diagonal brace opening 411 and a second diagonal brace opening 412. The first diagonal brace opening 411 is disposed on the diagonal brace base plate 40a, and the second diagonal brace opening 412 is disposed on the diagonal brace enclosure plate 40b.

[0056] In an optional embodiment, the first adapter 50 includes a first fixing plate 511 and a C-shaped first connecting section 512. The first connecting section 512 has a first mounting hole 513 located in the middle of the first fixing plate 511. The position of the first mounting hole 513 corresponds to the position of the hanger opening 31. The first fixing plate 511 is fixedly connected to the roof 100 by mechanical anchors, realizing an efficient connection between the hanger structure 30 and the roof 100. The first fixing plate 511 is used to withstand vertical tensile force and horizontal shear force, and the first connecting section 512 forms an anti-slip node to transfer loads.

[0057] In an optional embodiment, the second adapter 60 includes a second fixing plate 611 and a straight second connecting section 612. The second connecting section 612 has a second mounting hole 613 located in the middle of the second fixing plate 611. The position of the first mounting hole 513 corresponds to the position of the hanger opening 31 and the diagonal brace opening 41. The second fixing plate 611 is fixedly connected to the roof 100 by mechanical anchors, which optimizes the connection between the diagonal brace structure 40 and the roof 100 and achieves efficient lateral force transmission. The second fixing plate 611 is used to bear the horizontal component force transmitted from the diagonal brace, and the second connecting section 612 is used to transmit axial pressure.

[0058] In an optional embodiment, the third adapter 70 includes a mounting cavity with a first opening 71, the width of which is adapted to the width of the beam structure 20, so that the beam structure 20 can be inserted into the mounting cavity from the first opening 71 and fixed in the mounting cavity, thereby realizing the rapid nesting and fixing of the beam structure 20, and enabling the mounting cavity to wrap the beam structure 20, thereby increasing its node stiffness to two to three times that of traditional corner bracket connections.

[0059] In an optional embodiment, a second mounting hole 613 is provided on the upper end face of the mounting cavity, and a third mounting hole is provided on the lower end face of the mounting cavity. The position of the second mounting hole 613 corresponds to the position of the rod opening 31, and the position of the third mounting hole corresponds to the position of the beam opening 21, so as to realize the quick alignment and connection between the rod structure 30 and the third adapter 70, and the quick alignment and connection between the grid structure 10, the third adapter 70, and the beam structure 20, thereby forming an efficient force flow transmission path.

[0060] In an alternative embodiment, the beam structure 20 is fixed in the mounting cavity by adjusting bolts 80.

[0061] In an optional embodiment, the first adapter 50, the second adapter 60, and the third adapter 70 are provided with adjusting bolts 80. The adjusting bolts 80 pass through the beam opening 21, the hanger opening 31, and / or the brace opening 41 to realize the detachable connection between the first adapter 50, the second adapter 60, and the third adapter 70 and the beam structure 20, the hanger structure 30, and the brace structure 40.
