Description

Technical Field

[0001] This invention belongs to the field of marine interior decoration technology, specifically a detachable curved ceiling connection node. Background Technology

[0002] In the confined spaces of ships, and in the public areas of high-end vessels such as passenger roll-on / roll-off ships and cruise ships, there is a need for design features on the ceiling of the cabins. At the same time, it is also necessary to meet the needs of subsequent maintenance of valves and insulation in the hidden areas behind the ceiling. Therefore, the ceiling of the cabin usually needs to be removable.

[0003] The prior art document with publication number CN110273502B discloses a ceiling installation structure belonging to the technical field of interior decoration. It includes a hanger, a main keel, and secondary keels. The ceiling comprises multiple top panels, which are positioned between the secondary keels. Two elastic hanging plates are fixedly connected to one side of each top panel. The hanging plates are perpendicular to the top panel, with their top ends bent horizontally and then vertically downwards. The two hanging plates are parallel to each other and close to opposite ends of the top panels. The secondary keel includes a fixed plate, a support plate, and a connecting plate. The fixed plate is parallel to the connecting plate, and the support plate is perpendicular to the fixed plate. The support plate is fixedly connected to the fixed plate and the connecting plate. The fixed plate abuts against the bottom of the main keel. The connecting plate has vertical folded edges fixedly connected to its two ends on both sides of the support plate, with the top ends of the folded edges extending beyond the top of the connecting plate. An arc-shaped guide plate is fixedly connected between the fixed plate and the support plate. This invention provides a more stable ceiling fixation. Although the aforementioned devices facilitate the installation and removal of individual ceiling panels and ensure a more stable ceiling by using secondary keels and hanging plates, the limited space in ship cabins presents challenges. While curved ceilings can enhance functionality and aesthetics, traditional ceiling repairs require removing the entire ceiling and placing it in the cabin. However, the confined space of a ship often sees frequent foot traffic, which can easily deform the removed curved ceiling, hindering its reinstallation after repairs and causing unnecessary losses. Summary of the Invention

[0004] The purpose of this invention is to provide a detachable curved ceiling connection node that can be inspected without dismantling and is easy to dismantle and reposition, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a detachable curved ceiling connection node, comprising a suspension rod assembly and a steel plate, wherein multiple sets of suspension rod assemblies are provided, the top of each suspension rod assembly is fixedly connected to the steel plate, and multiple joists are fixedly connected to the bottom of each suspension rod assembly, the edges of which abut against multiple curved ceiling bodies, and further comprising: A detachable mechanism is connected to the curved ceiling body; A maintenance placement mechanism, which is connected to the keel; The detachable mechanism includes clamping plates fixed to both sides of the bottom of the keel. Each clamping plate has an outer wall abutting against a spring-loaded steel plate, and each spring-loaded steel plate has an inner side fixed with an elastic pad. The spring-loaded steel plate is in a teardrop-shaped, inclined, and bent state. Because the spring-loaded steel plate exhibits a teardrop-shaped bending state during installation, its bending angle is small. Therefore, even if the cabin is subjected to vibration, the spring-loaded steel plate will not fall off. Instead, through its elastic design combined with the support of the internal elastic pad, it effectively resists vibration and external forces, enhancing the stability and seismic resistance of the overall ceiling system. The detachable mechanism allows for convenient installation and removal of the ceiling. The teardrop-shaped design of the spring-loaded steel plate generates effective support during ceiling installation, ensuring the ceiling is firmly fixed. The maintenance placement mechanism is connected to the keel, providing convenience for subsequent maintenance.

[0006] Preferably, a pair of Z-shaped plates are fixedly connected to both sides of the top of the curved ceiling body, and the upper end of the elastic steel plate is fixedly inserted through the upper end of the Z-shaped plate.

[0007] Preferably, the Z-shaped plate has a groove in the middle, and the lower end of the elastic steel plate moves through the groove.

[0008] Preferably, a pair of arc plates are slidably connected between the pair of holes and the arc-shaped ceiling body, one end of the arc plate is elastically connected to the Z-shaped plate, and the other end of the arc plate is fixedly connected with a circular arc protrusion.

[0009] Preferably, a vertical plate is fixedly connected to the middle of the curved ceiling body, and a pair of L-shaped plates are fixedly connected to both sides of the vertical plate. The curved ceiling body can be easily restored to its original position. During the reset process, simply pull the ceiling body back to its original position and then continue to push it to the upward position until a "click" is heard. This means that the arc-shaped protrusion has reached the top of the second inclined slider. At this time, the overall weight of the ceiling body will cause it to move downward automatically, driving the first and second inclined sliders to slide down to the bottom of their respective grooves. During this process, the arc-shaped protrusion passes through the sliders in sequence and is finally restored to its original position by the squeezing action of the clamping plate, thus completing the reset of the ceiling.

[0010] Preferably, each of the elastic steel plates has a bent hook plate fixedly connected to its lower end. Multiple guide rods are fixedly connected to the inner wall of the hook of each bent hook plate. These guide rods slide through the side wall of the L-shaped plate, and the bent hook plate and the L-shaped plate are elastically connected to each other. During maintenance, the maintenance personnel push the ceiling body upwards. At this time, the second inclined slider compresses the elastic steel plate, causing it to contract towards the Z-shaped plate, thus not hindering the overall movement of the curved ceiling body. Through this structure, maintenance personnel can easily move the ceiling body upwards until the arc-shaped protrusion reaches the position of the locking plate. The arc-shaped protrusion will further push the curved plate towards the bottom of the Z-shaped plate, thus smoothly completing the disassembly or movement of the ceiling body. In this way, the ceiling body can be moved directly into the interior space of the suspended ceiling without disassembly, ensuring that the curved ceiling body can be accurately positioned and overlapped with adjacent ceiling bodies, thereby avoiding the loss or damage of the ceiling and preventing the impact on the ceiling caused by personnel movement within the cabin.

[0011] Preferably, the maintenance placement mechanism includes a pair of fixing plates fixed to the top of the keel, each fixing plate having a first sliding groove on its outer side, and the keel having a plurality of second sliding grooves symmetrically formed on both sides.

[0012] Preferably, each of the fixing plates is slidably connected to a first inclined slider via a first sliding groove, and the end of the vertical plate abuts against the arc plate and the arc protrusion. If the arc ceiling body needs to be disassembled for replacement, by pinching the bent hook plates on both sides and guided by the guide rod, the bent hook plates will push the lower end of the elastic steel plate towards the arc plate, making the elastic steel plate thinner and smoothly detach from the clamping plate. In this way, maintenance personnel can easily remove the arc ceiling body for replacement or repair. This disassembly process is very simple, which not only avoids occupying cabin space, but also effectively avoids equipment damage caused by improper operation during the disassembly process.

[0013] Preferably, the keel is slidably connected to a second inclined slider via a second sliding groove, and the second inclined slider abuts against the elastic steel plate; during reset, the first and second inclined sliders automatically slide down to the bottom of the first and second sliding grooves, so that the arc protrusion can automatically slide down along the slope of the two under the action of gravity.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the combination of a flexible steel plate, an elastic pad, and a circular arc protrusion, facilitates the direct movement of the curved ceiling body into the interior space of the suspended ceiling without disassembly. Depending on the application scenario, the ceilings of confined cabins are frequently disassembled. Maintenance personnel push the curved ceiling body upwards, and the second inclined slider compresses the flexible steel plate, causing it to retract towards the Z-shaped plate until a "click" is heard. After passing the second inclined slider, the circular arc protrusion and the curved plate reach the top of the keel for support, pushing the curved ceiling body into the interior space of the suspended ceiling. Under the limiting and guiding action of the fixed plate, the moving curved ceiling body overlaps with the top of adjacent curved ceiling bodies, eliminating the need for disassembly, not obstructing maintenance, effectively reducing space occupation, and not affecting the normal movement of personnel in the cabin. This prevents the disassembled ceiling from being accidentally stepped on and deformed, affecting secondary installation.

[0015] This invention facilitates the disassembly and repositioning of the curved ceiling body by using a combination of structures such as a bent hook plate, a first inclined slider, and a second inclined slider. If the curved plate needs to be disassembled for replacement, a plate must first be pushed upwards to expose the top of the adjacent curved ceiling body. The maintenance personnel can then directly reach out and pinch the bent hook plates on both sides to squeeze inwards, thinning the elastic steel plate until it can be easily removed from the clamping plate. This allows for complete removal of the curved ceiling body, facilitating replacement or repair. If repositioning is required, the overlapping curved ceiling bodies must be pulled back to their original positions. Then, the curved ceiling body is pushed again to continue moving upwards until the arc-shaped protrusion moves to the top of the second inclined slider. Immediately release the slider, and the curved ceiling body will automatically move downwards under its own weight, quickly resetting. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 10 As shown, the present invention provides a detachable curved ceiling connection node, including a hanger assembly 100 and a steel plate 300. Several sets of hanger assemblies 100 are provided, with the top of each hanger assembly 100 fixed to the steel plate 300. Multiple joists 200 are fixed to the bottom of each hanger assembly 100, and the edges of each joist 200 abut against several curved ceiling bodies 400. The invention also includes: The easy-to-disassemble mechanism 500 is connected to the curved ceiling body 400; Maintenance placement mechanism 600, which is connected to keel 200; The detachable mechanism 500 includes a clamping plate 590 fixed to both sides of the bottom of the keel 200. The outer wall of the clamping plate 590 is abutted against a spring steel plate 580. The inner side of the spring steel plate 580 is fixed with an elastic pad 560. The spring steel plate 580 is in a teardrop-shaped inclined bending state.

[0020] The above-mentioned scheme employs a suspension rod assembly 100, primarily composed of bolts, reinforcing bars, and connecting sleeves, used to connect the keel 200 and the steel plate 300, suspending the curved ceiling body 400. The suspension rod assembly 100 is fixed to the steel plate 300 at the top, ensuring the basic stability of the ceiling system, while its bottom connects to multiple keels 200, providing support for the curved ceiling body 400. The edges of the curved ceiling body 400 are connected to the clamping plate 590 via the keel 200. The outer wall of the clamping plate 590 is in close contact with the elastic steel plate 580, while the elastic pad 560 on the inner side of the elastic steel plate 580 increases seismic resistance and stability. The easy-to-remove mechanism 500 allows for convenient installation and removal of the ceiling. The teardrop-shaped design of the elastic steel plate 580 generates effective support during ceiling installation, ensuring the ceiling's secure fixation. The maintenance placement mechanism 600 connects to the keel 200, facilitating subsequent maintenance, making the entire structure not only stable during installation but also highly maintainable.

[0021] like Figures 2 to 10 As shown, a pair of Z-shaped plates 5100 are fixedly connected to both sides of the top of the curved ceiling body 400. The upper end of the elastic steel plate 580 is fixedly inserted through the upper end of the Z-shaped plate 5100. A slot 5110 is opened in the middle of the Z-shaped plate 5100, and the lower end of the elastic steel plate 580 is movably inserted through the slot 5110. A pair of curved plates 510 are slidably connected between the pair of slots 5110 and the curved ceiling body 400, and one end of the curved plate 510 is elastically connected to the Z-shaped plate 5100. Each of the arc plates 510 has a circular arc protrusion 570 fixedly connected to the other end; each of the arc ceiling body 400 has a vertical plate 520 fixedly connected to the middle, and each of the vertical plates 520 has a pair of L-shaped plates 540 fixedly connected to both sides; each of the elastic steel plates 580 has a bent hook plate 530 fixedly connected to the lower end, and each of the bent hook plates 530 has multiple guide rods 550 fixedly connected to the inner wall of the hook, and each of the guide rods 550 slides through the side wall of the L-shaped plate 540, and the bent hook plate 530 and the L-shaped plate 540 are elastically connected to each other.

[0022] Using the above scheme: During installation, when the lower end of the curved ceiling body 400 contacts a pair of elastic steel plates 580, the supporting force of the clamping plate 590 and the compression of the elastic steel plates 580 allow the elastic steel plates 580 to pass smoothly through the clamping plate 590. Upon resetting, the elastic steel plates 580 spring back outwards and abut against the surface of the keel 200. In this way, the curved ceiling body 400 can be firmly fixed to the ceiling system. Because the elastic steel plates 580 exhibit a teardrop-shaped bend during installation with a small bending angle, even if the cabin is subjected to vibration, the elastic steel plates 580 will not fall off. Instead, through their elastic design combined with the support of the internal elastic pads 560, they effectively resist vibration and external forces, enhancing the stability and seismic resistance of the overall ceiling system. During maintenance, repair personnel can select the curved ceiling body 400 below valves, insulation layers, and other devices, and push it upwards. During this process, the second inclined slider 630 compresses the elastic steel plate 580, causing it to retract towards the Z-shaped plate 5100, thus not hindering the overall movement of the curved ceiling body 400. This structure allows maintenance personnel to easily move the curved ceiling body 400 upwards until the arc-shaped protrusion 570 reaches the position of the locking plate 590. At this point, the arc-shaped protrusion 570 further pushes the curved plate 510 towards the bottom of the Z-shaped plate 5100, thus smoothly completing the disassembly or movement of the curved ceiling body 400. The process is smooth and efficient, ensuring unimpeded maintenance of equipment within the cabin. To avoid unnecessary space occupation or damage during ceiling disassembly, the curved ceiling body 400 can be moved directly into the interior space of the suspended ceiling without disassembly, guided by a guide mechanism. During this process, the limiting and guiding function of the fixing plate 610 ensures that the curved ceiling body 400 can be accurately positioned and overlapped with the adjacent curved ceiling body 400, thereby avoiding the loss or damage of the ceiling and also avoiding the impact on the ceiling caused by the movement of people in the cabin.

[0023] like Figure 4 , Figure 5 , Figure 7 and Figure 10 As shown, the maintenance placement mechanism 600 includes a pair of fixing plates 610 fixed to the top of the keel 200. The outer side of each fixing plate 610 is provided with a first sliding groove 650, and multiple second sliding grooves 640 are symmetrically provided on both sides of the keel 200. Each fixing plate 610 is slidably connected to a first inclined slider 620 through the first sliding groove 650. The end of the vertical plate 520 abuts against the arc plate 510 and the arc protrusion 570. The keel 200 is slidably connected to a second inclined slider 630 through the second sliding groove 640. The second inclined slider 630 abuts against the elastic steel plate 580.

[0024] Using the above solution: When disassembling the curved ceiling body 400, it must first be adjusted to a snap-fit ​​position, ensuring that the top of the adjacent curved ceiling body 400 is exposed, allowing maintenance personnel to operate easily. By pinching the elbow hook plates 530 on both sides, and guided by the guide rod 550, the elbow hook plates 530 will push the lower end of the elastic steel plate 580 towards the curved plate 510, causing the elastic steel plate 580 to thin and smoothly detach from the clamping plate 590. In this way, maintenance personnel can easily remove the curved ceiling body 400 for replacement or repair. This disassembly process is very simple, not only avoiding the occupation of cabin space, but also effectively preventing equipment damage caused by improper operation during disassembly. Through the synergistic effect of various mechanical structures such as the elastic steel plate 580, the curved plate 510, and the slider system, the entire system not only performs excellently in terms of stability and shock resistance, but also provides significant advantages in terms of space utilization, ease of maintenance, and operational safety. In addition, the design of the disassembly, installation and repositioning process of the curved ceiling body 400 reduces the difficulty of operation, improves maintenance efficiency, further enhances the comfort and safety of the working environment inside the cabin, meets the needs of the special environment inside the cabin, and ensures the efficient and stable operation of the ship during use.

[0025] Working principle and usage process of this invention: First, when installing the curved ceiling body 400, the upper and lower ends of the suspension rod assembly 100 are fixed to the steel deck 300 and the keel 200 respectively using bolts to form a suspended ceiling space. Then, the curved ceiling body 400 is moved from bottom to top, so that the surfaces of a pair of elastic steel plates 580 abut against the lower end of the clamping plate 590. Then, it is pressed upwards, compressing the elastic steel plates 580 and the internal elastic pad 560, allowing the elastic steel plates 580 to pass smoothly through the clamping plate 590. Under the return of elasticity, the pair of elastic steel plates 580 abut against the surface of the keel 200 outwards, completing the clamping installation of the curved ceiling body 400. In this way, the entire top of the cabin can be installed with curved ceiling bodies 400, and adjacent curved ceiling bodies 400 abut against each other through the curved plates 510 extending from both sides. The curved plates 510 extend the curvature of the curved ceiling body 400 while covering the gaps of the keel 200, forming a visually integrated suspended ceiling. Meanwhile, when the ship is rocking and vibrating, because the elastic steel plate 580 is in a teardrop-shaped inclined bending state with a small bending angle, the elastic steel plate 580 will only be compressed up and down when vibrating, and will not fall off on its own. Combined with the elastic support of the internal elastic pad 560, the vibration resistance of the curved ceiling body 400 is enhanced, and the stability of the installation of the curved ceiling body 400 is effectively improved. Secondly, when it is necessary to inspect the valves and insulation in the hidden area on the back of the curved ceiling body 400, the maintenance personnel need to select the appropriate curved ceiling body 400, then push the curved ceiling body 400 upwards. The second inclined slider 630 compresses the elastic steel plate 580 and retracts towards the Z-shaped plate 5100, without hindering the overall movement of the curved ceiling body 400, until the arc-shaped protrusion 570 reaches the position of the clamping plate 590. Continue pushing upwards until a "click" is heard. Under the pressure of the clamping plate 590, the arc-shaped protrusion 570 can push the curved plate 510 to retract towards the bottom of the Z-shaped plate 5100, so that... Figure 10 As shown. At this time, the two sides of the curved ceiling body 400 are mainly supported on the top of the keel 200 by the curved plates 510. Next, the curved ceiling body 400 is pushed towards the interior space of the ceiling. Under the limiting and guiding action of the fixing plate 610, the moving curved ceiling body 400 reaches the top of the adjacent curved ceiling body 400 and is placed overlapping, without needing to be removed. This does not hinder maintenance and avoids the situation of taking it out and placing it in the cabin. The cabin space is small, and if people walk back and forth, they may accidentally step on the curved ceiling body 400, causing it to deform. During reset, simply pull the curved ceiling body 400 back to its original position, then push the curved ceiling body 400 again to make it continue to move upward until you hear a "click" sound, indicating that the arc-shaped protrusion 570 has moved to the top of the second inclined slider 630. Then immediately release it, and the curved ceiling body 400 will automatically move downward under its own weight. At this time, the first inclined slider 620 and the second inclined slider 630 will automatically slide down to the bottom of the first slide groove 650 and the second slide groove 640. The arc-shaped protrusion 570 will pass through the first inclined slider 620 and the second inclined slider 630 in sequence. Finally, under the pressure of the inclined slope of the second inclined slider 630, the arc-shaped protrusion 570 will automatically pass through the clamping plate 590 and reach the bottom of the keel 200. It will automatically extend under the elastic force. At this time, the elastic steel plate 580 may slide down the slope. You need to push the curved ceiling body 400 up again to ensure that the clamping is secure. Secondly, when it is necessary to completely remove the curved ceiling body 400, the curved ceiling body 400 must be preserved first, such as... Figure 10 In this state, the keel 200 is engaged above it, at which point the top of the adjacent curved ceiling body 400 is exposed. Maintenance personnel can directly reach out and pinch the elbow hook plates 530 on both sides and squeeze them inward. Under the guidance of the guide rod 550, the elbow hook plates 530 drive the lower end of the elastic steel plate 580 to squeeze towards the curved plate 510, making the elastic steel plate 580 thinner until it can be easily removed from the clamping plate 590. In this way, the curved ceiling body 400 can be completely removed for replacement.
