Technical Field
[0001] This utility model relates to an outdoor curtain wall ceiling system, and in particular to a metal ceiling panel system with small gaps that is easy to disassemble. Background Technology
[0002] In recent years, with the development of the construction industry, metal panels have been widely used in exterior ceiling applications due to their aesthetic appeal, durability, and lightweight properties. For example:
[0003] Chinese utility model patent CN202320375937.1 discloses an indoor openable ceiling installation structure, including several square tubes. Several first fixing frames are installed on each square tube at equal intervals. An adjusting bolt and a limiting member are provided within each first fixing frame. The limiting member is sleeved on the adjusting bolt. The first fixing frame has slots for the tail end of the adjusting bolt and both ends of the limiting member to extend outwards. A pressure plate is sleeved on the adjusting bolt, located outside the first fixing frame. A rotating nut is installed at the tail end of the adjusting bolt. A compression spring is sleeved on the adjusting bolt between the rotating nut and the pressure plate. A cover plate fixing structure is formed between the first fixing frame and the pressure plate for quick installation and removal of a cover plate. No additional tools are required during installation, making it convenient and quick. Furthermore, the cover plate can be quickly removed and replaced if the rotating nut rusts. The ceiling can form an overall indoor ceiling with different undulating shapes to meet the requirements of different interior structures and is more aesthetically pleasing.
[0004] Chinese utility model patent CN202120706903.7 relates to a ceiling installation structure, including a keel, a suspension member connecting the top wall and the keel, and a ceiling panel installed below the keel. It also includes a connector. The upper end of the connector has a slot for engaging with the keel, and the slot has a clamping structure for horizontally holding the keel. The opening of the slot has a limiting structure for restricting the vertical movement of the connector. The ceiling panel has a retaining strip, and the lower end of the connector has a groove for engaging the retaining strip. Using a connector to connect the ceiling panel and the keel is simple, easy and quick to install and disassemble, and convenient for future maintenance and replacement.
[0005] As people's aesthetic standards improve, the requirements for installation gaps in metal panel ceilings are getting smaller and smaller. Currently, most companies in the industry use plug-in or hanging systems to deal with these small gap ceilings; however, these systems have a fatal flaw: they are difficult to disassemble.
[0006] Inside the ceiling, there are a large number of pipes and electromechanical equipment. When these devices need to be repaired, the ceiling panels need to be removed. In the past, projects used separate access panels to solve the repair problem, but this method has a significant impact on the facade effect. Therefore, the market demand for a metal panel ceiling system with small gaps and easy removal is becoming increasingly urgent.
[0007] Conventional small-gap metal panel ceiling systems mostly use hanging and plug-in methods. Since the safe overlap of hanging and plug-in is at least 10mm, it is impossible to remove individual aluminum panels when facing metal panels with gaps less than 10mm. You can only remove them from the edge to the required position, which involves a large amount of removal and is easy to damage the metal panel. Summary of the Invention
[0008] The technical problem this invention aims to solve is to provide a small-gap, easily removable metal panel ceiling system that meets the requirements of removability and restoration of individual aluminum panels with small gaps. It can achieve individual disassembly of metal panel ceiling systems with gaps of 6-10mm.
[0009] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a small-gap, easily removable metal ceiling panel system for outdoor curtain wall ceiling systems, including a main keel, a secondary keel, and metal panels. The metal panels are fixed to the keel by aluminum alloy subframes and metal reinforcing ribs. There are small gaps of no more than 10mm between the metal panels. Screw holes are provided at the groove below the main keel. The metal reinforcing ribs are first integrated with the aluminum alloy subframes, and then integrated with the metal panels. During installation, limit screws are tightened. After the metal panel is inserted into the groove of the main keel, the limit screws are unscrewed. During disassembly, a screwdriver is used to screw the limit screws into the gap between the metal panels to remove the limiting force, and the metal panel can be pulled out from the gap. This improves the surface flatness and wind load resistance of the metal panels.
[0010] Furthermore, the keel includes aluminum alloy keel A and aluminum alloy keel B. The aluminum alloy keel A is connected to the metal plate through symmetrically arranged metal reinforcing ribs at its lower part. The metal plate is fastened to the metal reinforcing ribs, forming a small gap for the horizontal connection of the metal plate. The aluminum alloy keel B is connected to the metal plate through an aluminum alloy subframe. The metal plate is inserted into the opening of the aluminum alloy subframe. The opening of the aluminum alloy subframe corresponds to the slot position of the aluminum alloy keel B, forming a small gap for the vertical connection of the metal plate.
[0011] Preferably, the small gap is 6-10mm.
[0012] Preferably, a groove is provided below the aluminum alloy keel B, and a limiting screw is fixed in the groove. The limiting screw is screwed into the groove, and after the metal plate is inserted into the opening of the aluminum alloy subframe, the limiting screw is unscrewed to complete the installation.
[0013] This invention effectively solves the problem of inconvenient disassembly of small-gap aluminum panel ceilings, achieving the ability to disassemble or replace individual ceiling panels without altering the building's appearance. Furthermore, it eliminates the need for separate access panels when inspecting internal pipework, ensuring the ceiling's integrity. This greatly satisfies the requirements for the disassembly and restoration of individual panels with small gaps. Simultaneously, the strength of the metal panels is enhanced, providing wind pressure resistance. Attached Figure Description

[0024] A small-gap, easily removable metal ceiling panel system for use in exterior curtain wall ceiling systems, such as... Figures 1 to 5 As shown, it includes a main keel, a secondary keel, and metal plates. The metal plates 01 are fixed to the keel by aluminum alloy subframes 07 and metal reinforcing ribs 04. There are small gaps of 6 to 10 mm between the metal plates 01. They are fixed on both sides, that is, the aluminum alloy subframes 07 are fixed to the keel on the long side, and the metal reinforcing ribs 04 are fixed to the keel on the short side to improve the flatness of the metal plates 01. There are screw holes in the groove below the main keel, and the limiting screws 08 are fixed to the main keel.
[0025] like Figure 3 and 4 As shown, the metal reinforcing rib 04 first forms an integral part with the aluminum alloy subframe 07, and then forms an integral part with the metal plate 01, thereby improving the surface flatness of the metal plate 01.
[0026] During installation, tighten the limit screw 08. After the metal plate 01 is inserted into the main keel groove, tighten the limit screw 08. During disassembly, use a screwdriver to tighten the limit screw 08 through the gap of the metal plate 01 to remove the limiting function. The metal plate 01 can then be pulled out of the gap. This improves the surface flatness and wind load resistance of the metal plate 01.
[0027] In this embodiment, the keel includes a secondary keel aluminum alloy keel A06 and a main keel aluminum alloy keel B09.
[0028] like Figure 1 As shown, the aluminum alloy keel A06 is connected to the metal plate 01 via symmetrically arranged metal reinforcing ribs 04 at its lower part. The metal plate 01 is fastened onto the metal reinforcing ribs 04, forming a small gap for the horizontal connection of the metal plate 01. EPDM rubber strips are used at the connection points between the symmetrically arranged metal reinforcing ribs 04 and the aluminum alloy keel A06, while structural adhesive is used at the connection points between the metal reinforcing ribs 04 and the metal plate 01. Furthermore, the metal reinforcing ribs 04 and the metal plate 01 are fixed together with nails.
[0029] like Figure 2 As shown, the aluminum alloy keel B09 is connected to the metal plate 01 through the aluminum alloy subframe 07. The metal plate 01 is inserted into the opening of the aluminum alloy subframe 07. The opening of the aluminum alloy subframe 07 corresponds to the slot of the aluminum alloy keel B09, forming a small gap between the vertical connections of the metal plate 01.
[0030] A slot 091 is provided below the aluminum alloy keel B09. A limiting screw 08 is fixed in the slot. The limiting screw 08 is screwed into the slot. After the metal plate 01 is inserted into the opening of the aluminum alloy sub-frame 07, the limiting screw 08 is unscrewed, completing the installation. Figure 5 As shown.
[0031] During on-site installation, the metal reinforcing rib 04 and the aluminum alloy subframe 07 are first assembled into a whole, and then assembled into a whole with the metal plate 01. After the aluminum alloy keel A06 and aluminum alloy keel B09 are installed on-site, screw holes are first drilled in the groove of the aluminum alloy keel B09, and the limit screw 08 is screwed in. After the metal plate 01 is inserted into the groove of the aluminum alloy keel B09, the limit screw 08 is unscrewed, and the installation is completed. During disassembly, a screwdriver is used to screw the limit screw 08 in through the gap to remove the limiting function, and the metal plate 01 can be pulled out of the gap. Disassembly is simple and convenient.
[0032] The features of this utility model are as follows:
[0033] 1. In terms of metal plate structure design: by increasing the reinforcing ribs, the flatness of the metal plate surface is improved. The plate is fixed on both sides, that is, the long side is fixed to the keel through an aluminum alloy subframe, and the short side is fixed to the keel through reinforcing ribs, which improves the flatness of the aluminum plate and its resistance to wind loads. The fixing method in the long side adopts a plug-in design.
[0034] 2. Metal plate disassembly structure design: The main keel is designed with grooves. First, screw in the screws. After the metal plate is installed and fixed in the groove, screw out a section of the screw to hold the aluminum plate in place and prevent the metal plate from coming out of the groove. Disassembly is done by using a small diameter screwdriver. Screw the screws in through the gap to release the metal plate limit and remove the aluminum plate.
[0035] The above description of the present invention is for illustrative purposes only and is not intended to limit the technical solutions described in the inventive examples. Various components in the present invention can be modified or equivalently replaced to achieve the same technological effect; as long as the usage requirements are met, they are all within the protection scope of the present invention.
