Description

Technical Field

[0001] This invention relates to the field of building engineering, and more particularly to a robust steel structure ceiling. Background Technology

[0002] A suspended ceiling refers to a type of decoration applied to the top of a room. Simply put, it refers to the decoration of the ceiling and is an important part of interior decoration.

[0003] Suspended ceilings serve to insulate, heat-insulate, sound-insulate, and absorb sound. They also act as a concealed layer for electrical, ventilation, air conditioning, communication, fire protection, and alarm piping and equipment.

[0004] Ceiling installation is a common part of home decoration. Ceilings are classified differently depending on the material of the decorative panels. The main basis for distinguishing ceiling types is the ceiling material itself, which includes: light steel keel gypsum board ceilings, gypsum board ceilings, mineral wool board ceilings, plywood ceilings, irregularly shaped long strip aluminum composite panel ceilings, square painted aluminum composite panel ceilings, stained glass ceilings, aluminum honeycomb perforated sound-absorbing panel ceilings, and whole-house duplex ceilings, etc. Ceilings play a significant role in the overall interior decoration; appropriate decoration of the ceiling not only beautifies the interior environment but also creates a rich and varied artistic image for the interior space. When choosing ceiling decoration materials and design schemes, the principles of being economical, sturdy, safe, aesthetically pleasing, and practical should be followed.

[0005] Based on the above understanding, the research and development direction in the ceiling field is also focused on lightweighting and robustness, with the two combined to ensure the safety of the ceiling during use.

[0006] Chinese patent application number 201711013117.3 discloses an integrated ceiling system, including a base, a mounting cover, an LED lighting unit, a ventilation unit, a baffle drive mechanism, and a wind deflector unit. The mounting cover is located above the base, and the base contains a first mounting cavity and a second mounting cavity. The first mounting cavity houses the LED lighting unit, and a lampshade assembly is located above the LED lighting unit. The mounting cover has a third mounting cavity and a fourth mounting cavity. The lampshade assembly is installed in the third mounting cavity, and locking components are located at both ends of the lampshade assembly. The second mounting... The cavity is equipped with an exhaust ventilation unit, one end of which is equipped with a baffle drive mechanism. The baffle unit can close the air outlet to avoid wasting resources when starting the heating equipment. Two sets of sealing rings are set on the lampshade assembly to prevent moisture from entering the lampshade. The automatic locking component facilitates the disassembly and internal maintenance of the lampshade. The technical solution proposed by the above invention improves the ceiling structure to make it easier to disassemble and maintain. However, it does not improve its own strength. During use, it is prone to deformation and collapse due to insufficient strength, and its service life is also limited. Summary of the Invention

[0007] Therefore, in response to the above problems, this invention proposes a robust steel structure ceiling, which solves the technical problem that the existing ceiling support structure is insufficient, making it prone to collapse and deformation during use, thus resulting in a short service life.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a robust steel structure ceiling, comprising a suspension rod assembly, a keel assembly, and a panel, wherein the suspension rod assembly is fixedly connected to the upper wall surface, and the keel assembly connects the suspension rod assembly and the panel;

[0009] The suspension rod assembly includes a first fixed end, a second fixed end, and a connecting rod. The first fixed end and the second fixed end are connected by the connecting rod. The first fixed end is fixedly connected to the upper wall surface, and the second fixed end is connected to the keel assembly. The connecting rod is an inner and outer tube sleeve structure, which can extend and retract along its own axis to adjust the height.

[0010] The keel assembly includes a main keel and a secondary keel. The main keel is connected to the second fixed end. The main keel is provided with a first connecting part. The secondary keel is detachably connected to the main keel through the first connecting part. The secondary keel is provided with a first mounting groove.

[0011] The panel is provided with a locking part, and the connection between the panel and the keel assembly is completed by locking the locking part into the first mounting groove.

[0012] Furthermore, a fixing hole is provided on the second fixing end. The fixing hole is a semi-enclosed structure. A fixing groove is provided on the fixing hole. The fixing groove extends into the fixing hole. The projection of the fixing hole on the vertical plane is an inverted triangle. The vertical cross-section of the main keel is an inverted triangle, which corresponds to the fixing hole. The first connecting part extends away from the fixing hole through the fixing groove.

[0013] Furthermore, the first connecting part includes an integrally formed first support plate, a second support plate, a third support plate, and a fourth support plate. The second support plate is parallel to the horizontal plane. There are two first support plates, which are symmetrically arranged at both ends of the top surface of the second support plate. The first support plate and the second support plate are perpendicular to each other. Support protrusions are provided on the opposite surfaces of the two first support plates. There are two third support plates, which are symmetrically arranged at both ends of the bottom surface of the second support plate and extend in the opposite direction to the height direction of the first support plate. The vertical cross-section of the third support plate is L-shaped. The third support plate is provided with a locking protrusion. The bottom surfaces of the third support plate and the second support plate together form a locking groove that cooperates with the secondary keel.

[0014] Furthermore, the secondary keel has a vertical cross-section with a horizontal elliptical structure. The secondary keel is defined to include an upper arc-shaped surface and a lower arc-shaped surface that are symmetrical to each other. The first mounting groove is disposed on the secondary keel at the position of the lower arc-shaped surface. A locking crossbar is disposed on the upper arc-shaped surface of the secondary keel. The locking crossbar and the locking groove are engaged with each other.

[0015] Furthermore, the fourth support plate is located at the center of the upper top surface of the second support plate, the bottom of the fourth support plate is perpendicular to the upper top surface of the second support plate, and the free end of the fourth support plate is folded in either direction of the two first support plates to form a semi-enclosed structure.

[0016] Furthermore, the fourth support plate is covered with an anti-slip rubber layer.

[0017] Furthermore, the vertical cross-section of the first mounting groove is an inverted V-shape. The first mounting groove includes an inlet and two mutually symmetrical locking channels that communicate with the inlet. The end of each locking channel is provided with a magnetic nut. The structure of the locking part corresponds to that of the first mounting groove. The locking part includes two mutually symmetrical locking extension plates. The locking extension plates are made of elastic metal material that deforms under force. The free end of each locking extension plate is provided with a magnetic ferrule. The magnetic ferrule and the magnetic nut magnetically engage with each other.

[0018] Furthermore, the opening angle of the locking extension plate on the vertical surface is smaller than the opening angle of the locking channel. When the panel and the secondary keel are engaged, the locking extension plate enters the locking channel through the inlet and moves to the end of the locking channel under the guidance of the locking channel, so that the magnetic suction part and the magnetic suction mother part magnetically engage with each other.

[0019] Furthermore, both the suspension rod assembly and the keel assembly are made of aluminum profiles.

[0020] Furthermore, the height of the connecting rod is adjustable from 15cm to 30cm.

[0021] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:

[0022] 1. Compared to existing suspended ceilings used in the construction industry, this invention achieves better support performance and a more robust effect through the cooperation of the suspension rod assembly, keel assembly, and panel, thereby extending its service life. Specifically, the improvement lies in the following: the suspension rod assembly includes a first fixed end, a second fixed end, and a connecting rod, wherein the connecting rod connects the first and second fixed ends, and the first fixed end is fixedly connected to the upper wall of the building. This ensures that the suspension rod assembly can be stably fixed to the upper wall of the building. The connecting rod is designed with an inner and outer tube interlocking structure, allowing it to extend and retract along the growth axis, i.e., it can extend and retract vertically to modify the ceiling structure. By changing its own height, the overall suspended height of the ceiling can be adjusted by changing its own length. The main keel serves as the main supporting structure of the ceiling. In this invention, the second fixed end of the main keel and the suspension rod assembly are connected to ensure the overall stability of the main keel frame. Then, the secondary keel is connected through the first connecting part set on the main keel. The main keel and the secondary keel are arranged in a mutually perpendicular structure, thus forming several square areas on the horizontal plane. The panel is movably installed with the secondary keel through the first mounting groove set on the secondary keel. Thus, all components are movably set, making installation and disassembly flexible and convenient, while also providing excellent sturdiness, suitable for long-term use, and with a long service life.

[0023] 2. A fixing hole is provided on the second fixing end, which is used to pass through the main keel. The fixing hole adopts a semi-enclosed structure and has a fixing groove that passes through the fixing hole. The fixing groove is to allow the first connecting part on the main keel to extend outward. The projection of the fixing hole on the vertical plane is an inverted triangle structure. This structural design ensures the stability of the main keel and the suspension rod assembly in the vertical direction and is not prone to deformation due to weight issues. At the same time, the main keel also adopts a hollow structure design, which further simplifies material costs and its own weight. And because it adopts the same triangular structure as the fixing hole, there is no problem of insufficient vertical support.

[0024] 3. The first connecting part on the main keel in this invention includes an integrally formed first support plate, second support plate, third support plate, and fourth support plate. The second support plate serves as a connecting element, with the first support plate positioned above it and connecting to the main keel. There are two first support plates, providing connections to the second support plate from both the left and right ends. The first and second support plates are perpendicular to each other, ensuring vertical support performance. The third support plate is located on the bottom surface of the second support plate and has a similar structure to the first support plate. Its free end is bent towards the center, forming an L-shaped vertical cross-section. Together with the bottom surface of the second support plate, it forms a locking groove that cooperates with the secondary keel. The main keel has multiple hollow structures, which simplifies the material and reduces weight. The structural layout ensures that it does not affect the support performance.

[0025] 4. In this invention, a fourth support plate is provided at the center of the top surface of the second support plate. The fourth support plate is bent to form a semi-enclosed structure. Its function is to store the wires of electrical appliances installed on the ceiling. The fourth support plate is covered with an anti-slip rubber layer, which can increase the friction with the wires, prevent them from falling off, and provide protection for the wires.

[0026] 5. In this invention, a first mounting groove is provided on the secondary keel. The first mounting groove is used to connect with the panel. The first mounting groove is set as a vertical cross-section with a herringbone structure. The first mounting groove includes an inlet and a locking channel symmetrical to the inlet. The inlet is to facilitate the entry of the locking part on the panel. As is well known, traditional ceiling panels are disassembled and installed piece by piece using horizontal sliding rails. Disassembly is very troublesome. It is necessary to remove one piece first, and then disassemble from the removal opening outwards. This is very tedious and time-consuming. Moreover, the disassembly process often causes deformation of the edges of the panel. This is because the first panel often needs to be pried open with tools when disassembling. If the edges of the panel are deformed, it will affect the overall aesthetics when reinstalling. In addition, gaps are created between the deformed panel and the surrounding panels, making it unstable. If the panel is unstable, it will cause the ambient airflow to cause it to shake, resulting in noise. The panel in this invention is provided with a locking part, which includes two mutually symmetrical locking extension plates. The locking extension plates are made of elastic metal material that can deform under external force. They can be made of aluminum alloy or stainless steel. The deformation can be caused by the material itself or by its thin structure. When the panel is installed with the keel assembly, the locking extension plate enters through the inlet on the first installation slide and moves along the locking channel until the free end of the locking extension plate abuts against the end of the locking channel. The difference between this installation method and the traditional installation mode is that each panel is installed in a straight up and down mode during the installation process. Any panel in any area of ​​the ceiling can be disassembled and installed. At the same time, the panel can be removed by suction cups during the disassembly and assembly process, and the edges of the panel will not be deformed.

[0027] 6. In this invention, a magnetic chuck is provided at the free end of the locking extension plate, and a magnetic chuck is provided at the end of the locking channel. When the panel is connected to the secondary keel, the magnetic chuck and the magnetic chuck magnetically engage with each other, preventing the panel from loosening or even falling off. The reason for setting the opening angle of the locking extension plate to be smaller than that of the locking channel is that when the panel is connected to the secondary keel, the locking extension plate will undergo elastic deformation as it moves along the locking channel. During the elastic deformation, an elastic force is generated. This elastic force is mainly for the later removal of the panel. The elastic force drives the locking extension plate to change to its initial state. That is, during installation, the panel will have an outward spring-back force due to the elastic force of the locking extension plate. However, when the locking extension plate is fully engaged with the locking channel, that is, when the magnetic clasp and the magnetic nut are magnetically engaged, the magnetic force is greater than the elastic force, and the panel can be firmly installed on the secondary keel. During disassembly, only the suction cup needs to exert a downward force on the panel. As long as the magnetic clasp and the magnetic nut separate, the panel will quickly spring back outward under the action of the elastic force of the locking extension plate itself, making the disassembly process very convenient.
