Description

Technical Field

[0001] This invention relates to the field of modular ceiling technology, and in particular to an assembled modular ceiling structure. Background Technology

[0002] The industrialization of construction is a development trend in the construction industry. Prefabricated decoration technology has significant application value and broad application prospects for improving the quality of construction projects and promoting the upgrading and modernization of the construction industry. Integrated ceilings are currently widely used in kitchens, bathrooms, commercial offices, public buildings, and other occasions, and are a very popular decorative ceiling method. Prefabricated modular ceilings (referred to as modular prefabricated ceilings) are the core components of the ceiling of prefabricated interior decoration systems: the ceiling is divided into several standard unit modules of uniform size that can be independently disassembled and assembled according to standardized modules. All components are prefabricated in the factory, and the entire construction site adopts dry and wet-free splicing and assembly. The ceiling system is assembled by means of hangers, light steel keel, and special buckle / mortise and tenon connectors.

[0003] However, existing technologies still have the following problems: Currently, modular ceiling panels and keel frames generally use a back-mounted snap-fit ​​rod connection structure. During installation, construction workers need to continuously lift the ceiling panels for high-altitude alignment, and then rely on external force to pound the panels to force the snap-fit ​​rods into the keel grooves. This method is not only labor-intensive but also carries high risks due to high-altitude operations. Furthermore, impact assembly can easily cause deformation and damage to the ceiling panel surface, and vibration can easily cause misalignment of adjacent ceiling panels, thus having certain limitations. Therefore, we propose a prefabricated modular assembly ceiling structure. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a new technical solution for prefabricated modular assembly ceiling structures.

[0005] The objective of this invention is achieved as follows: a prefabricated modular ceiling structure includes a ceiling panel and a frame, wherein a back panel is provided on the upper surface of the ceiling panel, and a keel groove is provided at the bottom of the keel frame, and further includes:

[0006] The pre-installation mechanism includes multiple sets. The back plate is detachably connected to the keel frame via the pre-installation mechanism. The pre-installation mechanism includes a fitting component, a fastening component, an adjusting component, and a fixing component. The fitting component is fitted to the inner wall of the keel groove on both sides by the fastening component. The fitting component is moved away from the inner wall of the keel groove by the adjusting component. The fitting component is fixedly connected to the back plate by the fixing component. A fixing head is provided on the outer side of the fitting component. The fixing head is detachably connected to the keel frame.

[0007] Optionally, the fitting component includes a mounting shell and two sets of irregularly shaped plates. The irregularly shaped plates are elastically rotatably mounted on the bottom of the mounting shell, and the two sets of irregularly shaped plates are symmetrically arranged. A rotating groove is provided on the side of the two sets of irregularly shaped plates that are far apart from each other. Multiple sets of friction wheels are rotatably installed inside the rotating groove. A stabilizing rod is fixedly installed at the center of the bottom of the mounting shell, and the bottom of the stabilizing rod is fixedly connected to the back plate through a fixing component.

[0008] Optionally, torsion springs are provided between the two ends of the irregular plate and the bottom of the mounting shell, so that the two sets of irregular plates are set apart from each other by the torsion springs. The fixing head is provided at one end of the mounting shell, and the irregular plate is connected to the fastening component in a transmission manner.

[0009] Optionally, the fastening component includes two sets of first toothed plates, and side plates are fixedly installed at both ends of the mounting shell. A transmission groove is opened on one side of the side plate. The first toothed plate is slidably installed inside the transmission groove. First gears are rotatably installed at both ends of one side of the transmission groove. Both sets of first gears are meshed with the first toothed plates. A rotating rod is fixedly installed in the middle of one side of the first gear. The rotating rod passes through one end of the mounting shell and is fixedly connected to the irregular plate.

[0010] Optionally, a hidden groove is provided at the bottom of the stabilizer bar, and a linkage rod is slidably installed inside the hidden groove. A first pull rope is fixedly installed at the bottom of both sets of first tooth plates. The first pull rope passes through the outside of the stabilizer bar to the inside of the hidden groove, and one end of the first pull rope is fixedly connected to the upper end of the linkage rod. The lower end of the linkage rod is fixedly connected to the back plate.

[0011] Optionally, the adjusting component includes two sets of second pull ropes, the upper ends of which are fixedly connected to the outer sides of two sets of irregular plates, and a collar is fixedly installed at the same end of each set of second pull ropes. The collar is slidably sleeved on the outer side of the stabilizing rod, and a guide sleeve is fixedly installed at the bottom of the collar. A second toothed plate is fixedly installed on the outer side of the guide sleeve. A second gear is meshed with one side of the second toothed plate. The second gear is rotatably connected to the outer side of the stabilizing rod. Another set of second toothed plates is meshed with one side of the second gear. The second toothed plate is lifted and lowered connected to the back plate.

[0012] Optionally, the fixing component includes multiple sets of connecting rods, all of which are rotatably connected to the outside of the stabilizing rod, and the lower ends of the multiple sets of connecting rods are rotatably connected to sliding seats. Multiple sets of guide rods are fixedly installed at the four corners of the upper surface of the back plate. The sliding seats are slidably sleeved on the outside of the guide rods. Side mounting plates are fixedly installed at both ends of the guide rods, and the guide rods are fixedly connected to the back plate through the side mounting plates.

[0013] Optionally, a return spring is sleeved on the outer side of the guide rod, and one end of the return spring is fixedly connected to one of the side mounting plates, while the other end of the return spring is fixedly connected to the sliding seat.

[0014] Optionally, lifting slots are provided at the four corners of the upper surface of the back plate. A hollow threaded shell is rotatably installed inside the lifting slot. A fixed top plate is threadedly connected to the outside of the hollow threaded shell. The fixed top plate is perpendicularly corresponding to the sliding seat. A hollow knob is fixedly installed at the upper end of the hollow threaded shell. The lower end of the linkage rod passes through the hollow knob and the hollow threaded shell in sequence and is fixedly connected to the lower end of the lifting slot.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention, through the pre-installation mechanism, allows workers to simply lift the ceiling panel and place the fitting component inside the keel groove. The ceiling panel can then fall downwards under its own weight. The two sets of irregularly shaped panels rotate away from each other due to the force of the ceiling panel falling downwards and the fastening component. As a result, the two sets of irregularly shaped panels will precisely fit against the inner wall of the keel groove with the weight of the falling ceiling panel. This allows the ceiling panel to form a pre-support by its own weight as soon as it is placed in the keel groove and released. Workers do not need to continuously support it, and it supports single-person assembly. Thus, without damaging the keel frame, it can effectively improve the installation efficiency of the ceiling panel and reduce the danger of working at height.

[0016] Secondly, the friction wheel design utilizes the high friction coefficient of rubber to effectively ensure the stability of the pre-installation of the ceiling panels. At the same time, in the pre-locking state, the friction wheel can slide laterally along the keel to conveniently adjust the alignment accuracy of the gaps between adjacent ceiling panels.

[0017] Furthermore, by adjusting the design of the components, the spacing between the two sets of irregularly shaped plates before they enter the keel groove can be adjusted, allowing the irregularly shaped plates to be stably fitted into keel grooves of different widths, thereby effectively improving the applicability and convenience of the pre-installation mechanism.

[0018] Through the design of the fastening components, when the two sets of irregularly shaped plates enter and adhere to the inner wall of the keel groove, when the workers release the ceiling panels they are supporting, the ceiling panels fall due to their own weight, which drives the first pull rope. The first pull rope can then control the first toothed plate to achieve relative rotation of the two sets of first gears. In turn, the first gears can control the relative rotation of the two sets of irregularly shaped plates, and the ends of the two sets of irregularly shaped plates that are far apart from each other can then be tightly adhered to the inner wall of the keel groove, thus achieving the effect of the ceiling panels forming pre-support by their own weight.

[0019] Through the design of the fixing components, the fixing components can use the extrusion method to transform the sliding connection between the linkage rod and the ceiling panel during pre-installation into a rigid fixed connection, thereby facilitating the stable connection and installation of the ceiling panel and the keel frame.

[0031] 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.

[0032] like Figures 1 to 9 As shown, a prefabricated modular ceiling structure includes a ceiling panel 3 and a frame 2. The ceiling panel 3 has a back panel 4 on its upper surface, and the frame 2 has a keel groove at its bottom. It also includes:

[0033] The pre-installation mechanism 1 is provided in multiple sets. The back plate 4 is detachably connected to the keel frame 2 through the pre-installation mechanism 1. The pre-installation mechanism 1 includes a fitting component 101, a fastening component 102, an adjusting component 104, and a fixing component 105. The fitting component 101 is fitted to the inner wall of the keel groove on both sides through the fastening component 102. The fitting component 101 is moved away from the inner wall of the keel groove through the adjusting component 104. The fitting component 101 is fixedly connected to the back plate 4 through the fixing component 105. A fixing head 103 is provided on the outer side of the fitting component 101. The fixing head 103 is detachably connected to the keel frame 2.

[0034] like Figures 1 to 9As shown, through the cooperation of the fitting component 101, fastening component 102, adjusting component 104 and fixing component 105, the ceiling panel 3 can form a pre-support by its own weight, so that the staff does not need to continuously lift the ceiling panel 3 for installation with the keel frame 2. At the same time, it can avoid damage to the keel frame caused by interference structure installation, further improving the practicality, installation convenience and safety of modular ceiling.

[0035] Furthermore, the bonding component 101 includes a mounting shell 1013 and two sets of irregular plates 1016. The irregular plates 1016 are elastically rotatably mounted on the bottom of the mounting shell 1013, and the two sets of irregular plates 1016 are symmetrically arranged. Rotation grooves are provided on the side of the two sets of irregular plates 1016 that are far apart from each other. Multiple sets of friction wheels 1012 are rotatably mounted inside the rotation grooves. A stabilizing rod 1014 is fixedly mounted at the bottom center of the mounting shell 1013. The bottom of the stabilizing rod 1014 is fixedly connected to the back plate 4 through a fixing component 105.

[0036] Specifically, such as Figures 1 to 9 As shown, the friction wheel 1012 described above has multiple sets of wave grooves 6 on its outer side, and the wave grooves 6 are formed laterally, which can effectively improve the friction coefficient of the friction wheel 1012 in contact with the inner wall of the keel groove, and further improve the stability of the ceiling panel 3 in forming a pre-support using its own weight.

[0037] Specifically, such as Figures 1 to 9 As shown, the two sets of irregular plates 1016 have clearance grooves in the middle of opposite sides, and the stabilizing rod 1014 is located between the two clearance grooves. Therefore, it can prevent the two sets of irregular plates 1016 from touching the stabilizing rod 1014 when they rotate relative to each other.

[0038] Furthermore, a torsion spring 1015 is provided between the two ends of the irregular plate 1016 and the bottom of the mounting shell 1013, so that the two sets of irregular plates 1016 are set away from each other through the torsion spring 1015, the fixing head 103 is provided at one end of the mounting shell 1013, and the irregular plate 1016 is connected to the fastening component 102 in a transmission connection.

[0039] like Figures 1 to 9 As shown, through the design of the torsion spring 1015, the two sets of irregular plates 1016 can be flipped relative to each other under the action of the torsion spring 1015 at both ends, so that the irregular plates 1016 can drive multiple sets of friction wheels 1012 to fit tightly against the inner wall of the keel groove, so that the ceiling panel 3 can be stably pre-installed using its own weight.

[0040] Secondly, the mounting shell 1013 can also slide laterally inside the keel groove through the design of the friction wheel 1012, so that the position between the ceiling panel 3 and the adjacent ceiling panel 3 can be finely adjusted after the pre-installation, thus avoiding gaps.

[0041] Furthermore, the fastening component 102 includes two sets of first toothed plates 1023. Side plates 1011 are fixedly installed at both ends of the mounting shell 1013. A transmission groove is opened on one side of the side plate 1011. The first toothed plates 1023 are slidably installed inside the transmission groove. First gears 1022 are rotatably installed at both ends of one side of the transmission groove. Both sets of first gears 1022 are meshed with the first toothed plates 1023. A rotating rod 8 is fixedly installed in the middle of one side of the first gear 1022. The rotating rod 8 passes through one end of the mounting shell 1013 and is fixedly connected to the irregular plate 1016. A hidden groove is opened at the bottom of the stabilizing rod 1014. A linkage rod 1024 is slidably installed inside the hidden groove. A first pull rope 1021 is fixedly installed at the bottom of both sets of first toothed plates 1023. The first pull rope 1021 passes through the outside of the stabilizing rod 1014 to the inside of the hidden groove. One end of the first pull rope 1021 is fixedly connected to the upper end of the linkage rod 1024. The lower end of the linkage rod 1024 is fixedly connected to the back plate 4.

[0042] like Figures 1 to 9 As shown, through the design of the fastening component 102, when the ceiling panel 3 falls due to its own weight, it causes the back panel 4 to fall. The back panel 4 is connected by the pre-linkage rod 1024. Pulling the first pull rope 1021 will pull the first toothed plate 1023, causing the first toothed plate 1023 to slide downward. Then, the first toothed plate 1023 can drive the two sets of meshing first gears 1022 on both sides to rotate. When the two sets of first gears 1022 rotate, they can drive the two sets of irregular plates 1016 to rotate relative to each other through the rotating rod 8, so that the friction wheel 1012 gradually squeezes the inner wall of the keel groove, achieving the function of the ceiling panel 3 forming a pre-support by its own weight.

[0043] Specifically, such as Figures 1 to 9 As shown, an arc-shaped plate 7 is fixedly installed at the bottom of the side plate 1011. The first pull rope 1021 is attached to the outside of the first pull rope 1021, which can prevent the first pull rope 1021 from rubbing against the edge of the side plate 1011, thus avoiding the first pull rope 1021 from being damaged due to friction stress concentration.

[0044] Secondly, such as Figure 5 The first pull rope 1021 also uses an arc shape where it passes through the outside of the stabilizer bar 1014. This avoids excessive stress concentration friction between the first pull rope 1021 and the stabilizer bar 1014 when the first pull rope 1021 enters the hidden groove, thus further preventing damage to the first pull rope 1021.

[0045] Furthermore, the adjusting component 104 includes two sets of second pull ropes 1041. The upper ends of the two sets of second pull ropes 1041 are fixedly connected to the outer sides of the two sets of irregular plates 1016, and a collar 1042 is fixedly installed at the same end of the two sets of second pull ropes 1041. The collar 1042 is slidably sleeved on the outer side of the stabilizer 1014. A guide sleeve 1043 is fixedly installed at the bottom of the collar 1042. A second toothed plate 1044 is fixedly installed on the outer side of the guide sleeve 1043. A second gear 1045 is meshed with one side of the second toothed plate 1044. The second gear 1045 is rotatably connected to the outer side of the stabilizer 1014. Another set of second toothed plates 1044 is meshed with one side of the second gear 1045. The second toothed plate 1044 is lifted and lowered connected to the back plate 4.

[0046] Specifically, such as Figures 1 to 9 As shown, each of the four corners of the upper surface of the back plate 4 is rotatably mounted with an adjusting threaded shell 1047, which is hollow and has threads on its inner wall. A lifting column 1046 is threadedly connected inside the adjusting threaded shell 1047, and the lifting column 1046 is slidably mounted to the upper surface of the back plate 4. A groove is provided at the upper end of the lifting column 1046. A sliding block 13 is fixedly mounted at the bottom of another set of second toothed plates 1044, and the sliding block 13 is slidably mounted inside the groove. A fastening spring 14 is fixedly mounted on one side of the sliding block 13, and one end of the fastening spring 14 is fixedly connected to one end inside the groove.

[0047] like Figures 1 to 9 As shown, through the cooperation of the lifting column 1046 and the adjusting threaded housing 1047, the height position of the other set of second toothed plates 1044 can be controlled. Therefore, the engagement timing between the other set of second toothed plates 1044 and the second gear 1045 can be adjusted according to the different width specifications of the keel groove. When installing with a wider keel groove, first move the other set of second toothed plates 1044 away from the second gear 1045, then rotate the adjusting threaded housing 1047 to control the lifting column 1046 to drive the other set of second toothed plates 1044 down, and then the fastening spring 14 controls the descent. Another set of second toothed plates 1044 are reset. When the irregular plate 1016 approaches the ceiling plate 3 by its own weight through the connecting and cooperating mounting shell 1013 and stabilizing rod 1014, the other set of second toothed plates 1044 will have a large window period to mesh with the second gear 1045 to control the second toothed plate 1044 connected to the guide sleeve 1043. For narrower keel grooves, the opposite operation can be performed. Therefore, the pre-installation mechanism 1 of the present invention can also be used according to keel grooves of different widths, thereby effectively improving the applicability of prefabricated modular ceilings.

[0048] Secondly, such as Figures 1 to 9As shown, firstly, through the design of the second pull rope 1041, the two sets of second toothed plates 1044 can move away from each other or move closer to each other through the second gear 1045. When the irregular plate 1016 above the ceiling plate 3 has not entered the keel groove, the irregular plate 1016 moves closer to the ceiling plate 3 by its own weight through the connecting and cooperating mounting shell 1013 and the stabilizing rod 1014 and other structures. At this time, the two sets of second toothed plates 1044 are in a state of moving closer to each other. When the second toothed plate 1044 connected to the guide sleeve 1043 moves downward, the guide sleeve 1043 can pull the irregular plate 1016 downward through the collar 1042, so that the two sets of irregular plates 1016 rotate closer to each other, so that it is convenient for the staff to put the fitting part 101 into the keel groove, and avoid the gap between the two sets of irregular plates 1016 being too large and difficult to put into the keel groove.

[0049] Furthermore, the fixing component 105 includes multiple sets of connecting rods 1051, all of which are rotatably connected to the outside of the stabilizing rod 1014, and each set of connecting rods 1051 is rotatably connected to a sliding seat 1059 at its lower end. Multiple sets of guide rods 1058 are fixedly installed at the four corners of the upper surface of the back plate 4. The sliding seat 1059 is slidably sleeved on the outside of the guide rod 1058. Side plates 1053 are fixedly installed at both ends of the guide rod 1058, and the guide rod 1058 is fixedly connected to the back plate 4 through the side plates 1053.

[0050] like Figures 1 to 9 As shown, the design of the guide rod 1058 and the sliding seat 1059 allows the stabilizer 1014 to be slidably connected to the back plate 4, while preventing the mounting shell 1013 from tilting and causing the irregular plate 1016 to unstablely drive the friction wheel 1012 into the keel groove.

[0051] Furthermore, a return spring 1052 is sleeved on the outer side of the guide rod 1058, and one end of the return spring 1052 is fixedly connected to one of the side mounting plates 1053, and the other end of the return spring 1052 is fixedly connected to the sliding seat 1059.

[0052] like Figures 1 to 9 As shown, through the design of the return spring 1052, the return spring 1052 can pull the sliding seat 1059 to slide outside the guide rod 1058, so that multiple sets of sliding seats 1059 can move closer to each other. Thus, when the ceiling panel 3 falls due to its own weight, the return spring 1052 can further increase the force of the ceiling panel 3 pulling the first pull rope 1021, thereby further improving the adhesion between the friction wheel 1012 and the inner wall of the keel groove.

[0053] Furthermore, lifting grooves are provided at the four corners of the upper surface of the back plate 4. A hollow threaded shell 10 is rotatably installed inside the lifting groove. A fixed top plate 9 is connected to the outside of the hollow threaded shell 10 by threads. The fixed top plate 9 is vertically corresponding to the sliding seat 1059. A hollow knob 11 is fixedly installed at the upper end of the hollow threaded shell 10. The lower end of the linkage rod 1024 passes through the hollow knob 11 and the hollow threaded shell 10 in sequence and is fixedly connected to the lower end of the lifting groove.

[0054] like Figures 1 to 9 As shown, through the cooperation of the hollow threaded shell 10 and the fixed top plate 9, after the position of the ceiling plate 3 is adjusted, the workers can control the hollow threaded shell 10 to rotate through the hollow knob 11 after installing all the necessary bolts, so that the fixed top plate 9 moves upward and at the same time presses and fixes multiple sliding seats 1059, thereby fixing the position of the irregular plate 1016.

[0055] Secondly, the fixed head 103 can be bolted to the keel frame 2 to further improve the stability of the connection between the irregular plate 1016 and the keel frame 2.

[0056] It should be noted that the sliding seat 1059 and the fixed top plate 9 mentioned above are made of high-strength cast polyurethane material on opposite sides. The sliding seat 1059 and the fixed top plate 9 supported by high-strength cast polyurethane material have a certain rigidity and high friction. When the fixed top plate 9 moves upward and presses against multiple sliding seats 1059, the sliding seats 1059 can be effectively fixed, thereby completing the fixed connection between the stabilizer 1014 and the back plate 4. The use of high-strength cast polyurethane material for parts is already a mature existing technology. Those skilled in the art should know how to install and use the sliding seat 1059 and the fixed top plate 9. Therefore, this invention will not be described in detail here.

[0057] Specifically, such as Figures 1 to 9 As shown, a sliding base 1054 is fixedly installed on one side of the sliding seat 1059, and the sliding base 1054 is slidably sleeved on the outside of the guide rod 1058. Two sets of connecting sleeves 1055 are slidably installed on the upper surface of the sliding base 1054, and the connecting sleeves 1055 are rotatably connected to one end of the connecting rod 1051. Both ends of one side of the sliding seat 1059 are slidably installed with pressing plates 1056, and the two sets of pressing plates 1056 are inclined on opposite sides. The pressing plates 1056 are located on the connecting sleeves 1058. At the bottom of 055, a sliding rod 1057 is fixedly installed on the upper surface of the sliding seat 1059, and the lower ends of the two sets of connecting rods 1051 are slidably sleeved on the outside of the sliding rod 1057. The upper ends of the two sets of connecting rods 1051 are movably connected to the outside of the stabilizing rod 1014. Multiple sets of fixing plates 12 are fixedly installed on the outside of the linkage rod 1024, and the fixing plates 12 are located between the two sets of connecting rods 1051. Extrusion grooves are opened on both sides of the upper surface of the fixed top plate 9, and the lower end of the extrusion plate 1056 is located inside the extrusion groove.

[0058] It should be noted that the upper ends of the two sets of connecting rods 1051 mentioned above are connected to the stabilizing rod 1014 with the same structure as the sliding rod 1057, so that the two sets of connecting rods 1051 can slide and clamp the fixing plate 12.

[0059] Through the design of the above-mentioned two sets of connecting rods 1051, extrusion plate 1056 and connecting sleeve 1055, when the fixed top plate 9 moves upward to extrude the sliding seat 1059, the extrusion plate 1056 inside the extrusion groove can be extruded first, so that the extrusion plate 1056 extrudes the connecting sleeve 1055. The two sets of connecting sleeves 1055 can move closer to each other through the extrusion of the extrusion plate 1056, and drive the connecting rod 1051 to extrude the fixed plate 12, so that the linkage rod 1024 and the stabilizing rod 1014 are fixed to each other. Therefore, the double fixation of the ceiling plate 3 and the irregular plate 1016 is achieved, thereby effectively improving the stability of the ceiling plate 3 during pre-support installation.

[0060] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
