Description

Technical Field

[0001] This invention relates to the field of building curtain walls, and in particular to an adjustable ultra-wide seamless ceiling system. Background Technology

[0002] Ceiling systems, as an important component of building curtain walls, are widely used in practical applications, with variations in their location and dimensions across different buildings. In recent years, with increasing building heights, ceiling systems have also been applied to sky bridges connecting two buildings, and the panel sizes are becoming increasingly larger. Since standard metal panels with folded edges generally do not exceed 1.5 meters on any single side, they cannot be excessively wide in both directions. If the building design requires excessively wide and large metal panels on both sides, custom orders must be placed with the manufacturer in advance, significantly increasing costs, compromising material delivery time, and potentially affecting project progress. In practice, oversized panels often exhibit significant deformation or even collapse, resulting in poor flatness after installation. Traditionally, ceiling systems are installed using scaffolding or suspended platforms. After positioning the panels, they are sequentially nailed to the metal frame at the bottom. Using traditional methods, on-site installation requires consideration of safety during high-altitude work on the suspended platform, bottom hoisting, and securing, which is clearly unsuitable for high-rise and super high-rise buildings. This increases construction costs and complexity. Summary of the Invention

[0003] The technical problem this invention aims to solve is to replace the traditional method of directly nailing panels and joists to the bottom of a building ceiling system with a combined ceiling system consisting of metal connectors, hanging metal sub-frames, assembled metal sub-frames, through bolts, connecting bolts, metal panels, limiting clips, and splicing bolts. Large-size metal panels can be divided into multiple smaller-size panels available in the market, based on factors such as transportation conditions, construction conditions, and stress. These smaller panels are then combined using silicone structural adhesive, assembled metal sub-frames, splicing bolts, and isolation gaskets. This allows the ceiling system to assemble two or more smaller panels into a complete two-way ultra-wide metal ceiling unit panel, achieving a seamless ultra-wide architectural appearance. The unit panel composed of hanging and assembled metal sub-frames ensures that the ultra-wide metal panels do not deform or sag. Because the hanging metal sub-frame and metal connectors are laterally fixed with a serrated interlocking mechanism, construction workers can adjust the elevation by positioning the serrated interlocking points. This operation can be performed from above the main structure, simplifying the installation process and eliminating the need for additional construction scaffolds or operating platforms. It ensures the installation speed, precision, and aesthetics of the ceiling system, reduces material and construction costs, and has significant social practical value.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] [An Adjustable Ultra-Wide Seamless Ceiling System] is a ceiling system composed of metal connectors, a hanging metal sub-frame, an assembly metal sub-frame, through bolts, EPDM adhesive strips, silicone structural adhesive, connecting bolts, metal panels, limit clips, splicing bolts, and isolation gaskets. This system can assemble multiple small-sized metal panels into a bi-directional ultra-wide panel as required by the design, without affecting the appearance and possessing strong resistance to deformation. The metal connectors and hanging metal sub-frames of the ceiling system can be adjusted vertically, solving the problem of unevenness in the main structure, unifying the height of the metal connectors, and allowing lateral installation and fixing to be completed above the main structure. The limit clips of the ceiling system serve to limit and prevent detachment, increasing the structural safety of the ceiling and achieving a seamless, aesthetically pleasing appearance.

[0006] 1. The materials used for the metal connectors, hanging metal sub-frames, assembly metal sub-frames, and limiting buckles of the ceiling system are: aluminum alloy, stainless steel, and carbon steel; the materials used for the metal panels are: aluminum single-layer panels, honeycomb core aluminum panels, and honeycomb stainless steel panels.

[0007] 2. The metal panel of the ceiling system is composed of two or more small-sized metal panels with isolation gaskets at the joint position, inserted into the assembly metal sub-frame according to the panel division position, and connected and fastened by splicing bolts to assemble a complete and seamless ultra-wide metal panel; 3. The assembly metal sub-frame and hanging metal sub-frame of the ceiling system are bonded to the metal panel with silicone structural adhesive and act as reinforcing ribs to form a frame unit panel, which can achieve no deformation of the ceiling system;

[0008] 4. The metal connectors and the hanging metal sub-frame of the ceiling system are designed with serrated textures. By positioning the serrated interlocking position of the two components, the ceiling system can be adjusted up and down during installation.

[0009] 5. The metal sub-frame and metal connector of the ceiling system are pre-drilled and then engaged for positioning. They are then connected and fixed from the side by through bolts, so that the ceiling system can be installed from above.

[0010] 6. The limiting buckle is embedded in the installed metal plate to prevent the metal plate and connecting bolts from falling off laterally and to achieve a tight and seamless splicing effect;

[0011] The beneficial effects of this utility model are as follows: This ceiling system can be pre-assembled into a complete two-way ultra-wide metal panel through metal connectors, hanging metal sub-frames, assembling metal sub-frames, through bolts, EPDM adhesive strips, silicone structural adhesive, connecting bolts, metal panels, limit buckles, splicing bolts, and isolation gaskets. It has high strength and rigidity, and strong resistance to deformation. It also has an adjustable installation direction, providing great flexibility. The assembled ceiling metal panel has an appearance identical to the customized ultra-wide metal panel, without changing the original design requirements. The connection method also ensures the installation quality, speed, cost, and construction safety requirements of the ceiling system, making it suitable for industrialized and large-scale production, and possessing significant social practical value.

[0016] The present invention will be further described below with reference to specific embodiments. These embodiments are only used to further illustrate the present invention and do not limit the scope of protection of the present invention:

[0017] Based on calculations, the segment lengths and spacing of metal connector 1 were determined. Vertical elongated holes were pre-machined on the connecting side of metal connector 1 before installation onto the main structure. The required size of the extra-wide metal panel 8 on both sides was determined to be divided into several smaller metal panels 8. Adjacent smaller metal panels 8 were then inserted into the assembly metal sub-frame 3 after being padded with isolation pads 11 on the outer side of the same side. After positioning and leveling, they were fixed with splicing bolts 10 at the calculated spacing. The outer ring of the spliced ​​metal panel 8 was then fixed to the hanging metal sub-frame 2, which had EPDM adhesive strips 5 inserted, using connecting bolts 7. Subsequently, the gaps between the assembly metal sub-frame 3, the hanging metal sub-frame 2, and the metal panel 8 were bonded with silicone structural adhesive 6. After static curing, the splicing positions of the metal panel 8 were welded, ground, and sprayed. At this point, the extra-wide metal panel on both sides required by the project design was assembled ahead of schedule. After surveying and setting out, the ceiling panels are placed on the working surface. The metal sub-frames 2 on the assembled metal panels 8 engage with the pre-installed metal connectors 1. After adjusting the height to ensure accuracy, the through bolts 4 are inserted into the pre-drilled holes on the components and tightened. After all ceiling system components are connected, the limiting clips 9 are inserted. After the above procedures are completed, the outer side of the ceiling system metal panels 8 has a seamless, tightly joined structure, while the inner side is assembled as a single unit. This ensures the safety and aesthetics of the ceiling system.
