TECHNICAL FIELD
[0001] The utility model relates to the field of aluminum alloy polyurethane ceiling board, especially to an aluminum alloy polyurethane ceiling board with reinforcing ribs. BACKGROUND
[0002] Aluminum alloy polyurethane ceiling board is an innovative building material, which is composed of two layers of aluminum alloy plates and a polyurethane sandwich layer in between. This ceiling board combines the lightweight, strong, corrosion-resistant, and high plasticity of aluminum alloy, as well as the excellent thermal insulation, sound insulation, and waterproof properties of polyurethane. The aluminum alloy provides a stable foundation structure for the board, while the polyurethane sandwich layer effectively improves the thermal insulation effect of the ceiling, reducing energy transfer and helping to reduce building energy consumption. At the same time, the aluminum alloy polyurethane ceiling board also has the advantages of fire safety, environmental protection and energy saving, and strong durability, which can meet the all-round demand of modern buildings for functionality, aesthetics, and sustainability. In addition, its surface can be diversified to achieve personalized design, suitable for various decoration styles and scenes.
[0003] In the prior art, although the aluminum alloy polyurethane ceiling board has high strength and corrosion resistance, when used in large span or large area, its own strength is not enough to support its own weight and external pressure, which is easy to cause deformation or damage, and is more prone to deformation under stress. During long-term use, this deformation may gradually intensify, leading to loose or falling of the ceiling board, thereby not only reducing the load capacity and stability of the aluminum alloy polyurethane ceiling board in actual use, but also reducing the safety during use. SUMMARY
[0004] The main purpose of the utility model is to provide an aluminum alloy polyurethane ceiling board with reinforcing ribs, which can effectively solve the problems in the background art.
[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:
[0006] An aluminum alloy polyurethane ceiling board with reinforcing ribs, comprising a polyurethane sandwich panel and an aluminum alloy base plate, the top surface and bottom surface of the polyurethane sandwich panel are respectively fixedly connected with the aluminum alloy base plate through a connecting mechanism, and the connecting mechanism comprises a reinforcing rib plate, a bidirectional adjusting threaded rod, a movable plate, and a clamping block, the top surface and bottom surface of the polyurethane sandwich panel are respectively embedded with the reinforcing rib plate formed by interlacing a plurality of horizontal ribs and vertical ribs, the bidirectional adjusting threaded rod is movably connected in the four corner end parts of the top surface of the polyurethane sandwich panel through the rotating rods at both ends, and the two movable plates are movably connected with the bidirectional adjusting threaded rod through the threaded holes on the side walls, and the outer side walls of the movable plates are respectively fixedly connected with symmetrical clamping blocks and fixedly connected with the aluminum alloy base plate through the clamping blocks.
[0007] Preferably, a plurality of the transverse and longitudinal stiffeners are connected in an interlaced manner to form a grid-shaped reinforcing rib plate.
[0008] Preferably, the top and bottom surfaces of the polyurethane sandwich panel are respectively provided with rib grooves, and the reinforcing ribs are embedded in the grooves.
[0009] Preferably, the four corners of the inner surface of the aluminum alloy substrate are provided with movable grooves, and the front and rear end walls of the movable grooves are provided with slots.
[0010] Preferably, the polyurethane sandwich panel has limit grooves at the four corners of its top surface, and the front and rear end walls of the limit grooves are provided with rotating holes. The front and rear end walls of the polyurethane sandwich panel are also provided with adjustment holes that communicate with the front rotating holes.
[0011] Preferably, rotating rods are fixedly installed at both ends of the bidirectional adjusting threaded rod, and the rotating rods are movably installed in the rotating holes. A concave hexagonal head is also fixedly installed on the outer end wall of the front rotating rod, and the concave hexagonal head is movably installed in the adjusting hole. A symmetrical set of movable plates is provided, and the movable plates are movably installed in the limiting through grooves. Threaded holes are opened on the side walls of the movable plates and are threadedly connected to the bidirectional adjusting threaded rod through the threaded holes. A symmetrical set of locking blocks is fixedly installed on the opposite side walls of the symmetrical movable plates and inserted into the locking slots.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In this invention, the connecting mechanism, in conjunction with the use of aluminum alloy polyurethane ceiling panels, embeds the reinforcing ribs into the grooves opened in the polyurethane sandwich panel, and then installs the aluminum alloy substrate onto the surface of the polyurethane sandwich panel. The movable plates protruding from the four corners of the top and bottom surfaces of the polyurethane sandwich panel are placed in the movable grooves opened in the aluminum alloy substrate. An auxiliary tool rotates the concave hexagonal head located in the adjustment hole, causing the concave hexagonal head to drive the bidirectional adjusting threaded rod to rotate via a rotating rod. This allows the symmetrical movable plates to move in opposite directions through the threaded holes on the side walls along the bidirectional adjusting threaded rod in the limiting grooves until the locking blocks installed on the outer side walls of the movable plates are inserted into the locking slots on the end walls of the movable grooves opened on the opposite sides of the upper and lower aluminum alloy substrates. This allows the polyurethane sandwich panel, aluminum alloy substrate, and reinforcing ribs to be quickly connected and fixed together. The assembly operation is simple and quick, and ensures that the polyurethane sandwich panel, aluminum alloy substrate, and reinforcing ribs will not separate due to external factors.
[0014] Meanwhile, a cross-bracing grid-shaped reinforcing rib plate, composed of several intersecting horizontal and vertical ribs, is arranged between the polyurethane sandwich panel and the aluminum alloy substrate and embedded inside the polyurethane sandwich panel. This built-in reinforcing rib plate structure increases the overall strength and rigidity of the aluminum alloy polyurethane ceiling panel during use. This allows the panel to better resist deformation under external forces, maintaining structural integrity and stability. Furthermore, the horizontal and vertical ribs effectively disperse stress, preventing damage, loosening, or detachment due to excessive stress. Therefore, this not only improves the load-bearing capacity and stability of the aluminum alloy polyurethane ceiling panel during actual use but also enhances its safety. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] like Figure 1 - Figure 4As shown, a polyurethane ceiling panel with reinforcing ribs includes a polyurethane sandwich panel 1 and an aluminum alloy substrate 2. The top and bottom surfaces of the polyurethane sandwich panel 1 are fixedly connected to the aluminum alloy substrate 2 via a connecting mechanism 3. The connecting mechanism 3 includes a reinforcing rib plate 6, a bidirectional adjusting threaded rod 13, a movable plate 16, and a locking block 18. The top and bottom surfaces of the polyurethane sandwich panel 1 are respectively embedded with a reinforcing rib plate 6 formed by several horizontal ribs 4 and vertical ribs 5. The bidirectional adjusting threaded rod 13 is movably connected to the four corners of the top surface of the polyurethane sandwich panel 1 via rotating rods 14 at both ends. The two movable plates 16 are movably connected to the bidirectional adjusting threaded rod 13 via threaded holes 17 on the side walls. Symmetrical locking blocks 18 are also fixedly connected to the outer side walls of the movable plates 16 and are fixedly connected to the aluminum alloy substrate 2 via the locking blocks 18.
[0022] like Figure 2 As shown, several horizontal stiffeners 4 and vertical stiffeners 5 are connected in an interlaced manner to form a grid-shaped reinforcing rib plate 6. The reinforcing rib plate 6 can disperse the pressure borne by the aluminum alloy polyurethane ceiling panel through the horizontal stiffeners 4 and vertical stiffeners 5, thereby improving the load-bearing capacity and stability of the aluminum alloy polyurethane ceiling panel in actual use.
[0023] like Figure 2 As shown, the top and bottom surfaces of the polyurethane sandwich panel 1 are respectively provided with rib grooves 7, and the reinforcing rib 6 is embedded in the grooves of the rib grooves 7. The embedded design can prevent the reinforcing rib 6 from shifting or separating between the polyurethane sandwich panel 1 and the aluminum alloy substrate 2.
[0024] like Figure 2 and Figure 3 As shown, movable grooves 8 are respectively provided at the four corners of the inner surface of the aluminum alloy substrate 2. The movable grooves 8 can ensure that the movable plate 16 can move within them. The front and rear end walls of the movable grooves 8 are respectively provided with slots 9, which are used to connect and fix the aluminum alloy substrate 2 with the slot block 18.
[0025] like Figure 2 and Figure 4 As shown, the polyurethane sandwich panel 1 has four corner openings on its top surface. The limiting slots 10 are used to cooperate with the movable plate 16 to achieve limiting movement. The limiting slots 10 also have rotating holes 11 on the front and rear end walls. The rotating holes 11 are used to cooperate with the rotating rod 14 to achieve rotation. The front and rear walls of the polyurethane sandwich panel 1 also have adjustment holes 12 that communicate with the front rotating hole 11. The adjustment holes 12 are used to cooperate with the movable rotation of the concave hexagonal head 15.
[0026] like Figure 4As shown, rotating rods 14 are fixedly installed at both ends of the bidirectional adjusting threaded rod 13, and the rotating rods 14 are movably installed in the rotating hole 11. A concave hexagonal head 15 is also fixedly installed on the outer end wall of the front rotating rod 14, and the concave hexagonal head 15 is movably installed in the adjusting hole 12. A symmetrical set of movable plates 16 is provided, and the movable plates 16 are movably installed in the limiting through groove 10. A threaded hole 17 is opened on the side wall of the movable plate 16, and the movable plate 16 is threadedly connected to the bidirectional adjusting threaded rod 13 through the threaded hole 17. A set of symmetrical locking blocks 18 are fixedly installed on the opposite side of the symmetrical movable plate 16 and inserted into the locking slot 9. By rotating the concave hexagonal head 15 with an auxiliary tool, the concave hexagonal head 15 drives the bidirectional adjusting threaded rod 13 to rotate through the rotating rod 14. This allows the symmetrical movable plate 16 to move in opposite directions through the threaded hole 17 along the bidirectional adjusting threaded rod 13 until the locking blocks 18 enter the locking slot 9, thus connecting and fixing the polyurethane sandwich panel 1, aluminum alloy substrate 2 and reinforcing rib plate 6 together.
[0027] The specific operating principle of the connecting mechanism 3 in conjunction with the aluminum alloy polyurethane ceiling panel is as follows:
[0028] When connecting and fixing the polyurethane sandwich panel 1 and the aluminum alloy substrate 2, reinforcing ribs 6, which are formed by several interlaced transverse ribs 4 and longitudinal ribs 5, are respectively embedded into the corresponding rib grooves 7 opened on the top and bottom surfaces of the polyurethane sandwich panel 1. Then, the aluminum alloy substrate 2 is installed on the top and bottom surfaces of the polyurethane sandwich panel 1, and the movable plates 16 protruding from the four corners of the top and bottom surfaces of the polyurethane sandwich panel 1 are respectively placed in the movable grooves 8 opened at the four corners of the opposite sides of the aluminum alloy substrate 2. By rotating the concave hexagonal head 15 in the adjustment hole 12 opened on the front and back of the polyurethane sandwich panel 1 with an auxiliary tool, the concave hexagonal head 15 will drive the rotating rods 14 at both ends of the bidirectional adjusting threaded rod 13 to limit the through groove. Rotating within the rotating holes 11 on both end walls of the inner 10, the rotating rod 14 drives the bidirectional adjusting threaded rod 13 to rotate within the limiting through groove 10. This causes the symmetrical movable plates 16 to move in opposite directions within the limiting through groove 10 via the threaded holes 17 on their side walls, following the bidirectional adjusting threaded rod 13, until the symmetrical locking blocks 18 installed on the outer side walls of the movable plates 16 are inserted into the locking slots 9 on both end walls of the movable groove 8, preventing the concave hexagonal head 15 from rotating further. This fixes the aluminum alloy substrate 2 onto the outer surface of the polyurethane sandwich panel 1 and restricts the reinforcing rib 6 within the rib groove 7 on the polyurethane sandwich panel 1. Thus, during actual use of the aluminum alloy polyurethane ceiling panel, the reinforcing rib 6... The reinforcing rib 6 is embedded within the polyurethane sandwich panel 1 and positioned between the polyurethane sandwich panel 1 and the aluminum alloy substrate 2. The reinforcing rib 6 is a grid formed by several interlaced transverse ribs 4 and longitudinal ribs 5, acting as a reinforcing network within the aluminum alloy polyurethane ceiling panel. This network, composed of interlaced transverse and longitudinal ribs, provides additional support and stability to the aluminum alloy polyurethane ceiling panel, increasing its overall strength and rigidity. When subjected to external forces, it better resists deformation, maintaining structural integrity and stability. It effectively disperses stress, preventing deformation or damage caused by excessive stress at a single point. The reinforcing rib 6 further strengthens the aluminum alloy... When subjected to external forces, the aluminum alloy polyurethane ceiling panel can better maintain its shape and size stability, making it less prone to deformation or sagging during long-term use, thus extending its service life. At the same time, due to the enhanced internal structural support, the aluminum alloy polyurethane ceiling panel can withstand greater loads without damage, ensuring the safety and stability of the aluminum alloy polyurethane ceiling panel during use. Finally, through the combined connection of polyurethane sandwich panel (1), aluminum alloy base plate (2) and reinforcing rib plate (6), if a part is damaged, it can be disassembled and replaced in time without replacing the entire aluminum alloy polyurethane ceiling panel, reducing the cost of using the aluminum alloy polyurethane ceiling panel.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
