Description

Technical Field

[0001] This utility model relates to the field of ceiling construction technology, and more specifically, to an adjustable cable-mounted installation structure suitable for large ceilings. Background Technology

[0002] To achieve the desired acoustic or visual effects in interior spaces, many large buildings often employ unique, large-scale irregularly shaped ceiling structures.

[0003] The common method for installing and fixing suspended ceilings is to directly connect the ceiling to the upper building structure using vertical hangers. For large suspended ceiling structures, a large number of hanging points are required to ensure sufficient lifting force. However, the irregular shape of the ceiling means that the length of the hangers at different hanging points will vary, and it is difficult to determine accurately through calculation. This undoubtedly brings great difficulty to the construction. Moreover, after the ceiling is installed and fixed using these hangers, it is difficult to further check and adjust the height or angle of the ceiling to meet the design requirements. Therefore, the installation of such large, irregular suspended ceiling structures has become one of the key and difficult points in the construction process.

[0004] In addition, the ceiling installation structure formed by multiple hangers is a highly statically indeterminate structure. Errors in the processing and installation of the hanger lengths will cause the internal forces of each hanger to deviate significantly from the design values ​​and be unevenly distributed. As a result, local stress concentrations may occur on the ceiling, which may further lead to deformation, arching or cracking of the ceiling itself, affecting the overall decorative effect and even safety.

[0006] The solution adopted by this utility model to solve the technical problem is:

[0007] An adjustable cable-mounted installation structure suitable for large suspended ceilings includes adjustable hangers for connecting the suspended ceiling and structural panels, and multiple sets of suspension cable structures for connecting the suspended ceiling and structural panels and located between the suspended ceiling and structural panels.

[0008] In some possible implementations, the adjustable suspension rod includes an adjusting rod and a threaded rod that is screwed to the adjusting rod and moves axially along the adjusting rod; one end of one set of the threaded rods away from the adjusting rod is connected to the structural plate, and the other end of the threaded rods away from the adjusting rod is connected to the ceiling.

[0009] In some possible implementations, the suspension structure includes multiple sets of fixed pulley assemblies respectively installed on the structural slab and the ceiling on opposite sides; a rope with one end connected to the structural slab and the other end passing through the multiple sets of fixed pulley assemblies and connected to the structural slab in sequence; and a drum assembly with one end of the rope connected to the structural slab and used for winding and unwinding the rope; the fixed pulley assemblies are rotatably connected to the structural slab and the ceiling.

[0010] In some possible implementations, the drum assembly includes a drum support rotatably connected to a structural plate, a drum rotatably mounted on the drum support and connected to one end of a rope, and a ratchet mechanism mounted on the drum support and used in conjunction with the drum.

[0011] In some possible implementations, a guide wheel is provided on the drum support, which rotates in conjunction with the drum support, and the axis of the guide wheel is parallel to the axis of the drum; the guide wheel is located below the drum; one end of the rope passes through the guide wheel and is connected to the drum.

[0012] In some possible implementations, both the fixed pulley assembly and the guide wheel are V-shaped pulleys.

[0013] In some possible implementations, the ratchet mechanism includes a ratchet coaxially connected to the drum and a pawl rotatably mounted on a support and engaged with the ratchet.

[0014] In some possible implementations, multiple sets of lifting rings connected to the roller assembly and adjustable hanger rods are provided on the side of the structural plate and the ceiling that are close to each other.

[0016] In some possible implementations, the rod body includes at least two sets of connecting rods of equal length and arranged in parallel, and a fastener for fixing the two sets of connecting rods.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model connects the structural plate to the ceiling by setting a suspension structure, which avoids the problems of calculating and processing the length of the suspension rods during the ceiling installation process. At the same time, it also ensures that the hoisting force at each connection point on the ceiling is relatively uniform, reduces stress concentration inside the ceiling, prevents the ceiling from cracking and deforming, and improves the quality and safety of ceiling installation.

[0028] The present invention will now be described in detail.

[0029] like Figures 1-6 As shown:

[0030] An adjustable cable-mounted structure suitable for large suspended ceilings 6 includes an adjustable hanger 5 for connecting the suspended ceiling 6 and a structural panel, multiple sets of suspension cable structures for connecting the suspended ceiling 6 and the structural panel and located between the suspended ceiling 6 and the structural panel, and multiple sets of lifting rings 1 installed on the side of the structural panel and the suspended ceiling 6 close to each other and connected to the roller assembly 4 and the adjustable hanger 5.

[0031] The lifting ring 1 can be made of 10mm diameter round steel bent into shape; the length of the straight section of the lifting ring 1 can be determined according to the stress conditions to ensure sufficient anchorage length. It is fixed to the structural plate or ceiling 6, providing connection points for the drum assembly 4 and the adjustable suspension rod 5, and directly bearing the load of the ceiling 6 being lifted; through the setting of the suspension structure, multi-directional connection is supported, without requiring the lifting points on the structural plate and the ceiling 6 to be vertically aligned, reducing the difficulty of the lifting point layout; especially in the case where the upper part is a steel structure, some locations cannot be set with lifting points due to structural conditions, and lifting points can be set directly at the side to provide lifting force for the ceiling 6 in that part, increasing the flexibility of the installation operation.

[0032] In some possible implementations, the adjustable rod 5 includes an adjusting rod and a threaded rod 51 that is screwed to the adjusting rod and moves axially along the adjusting rod; one end of one set of the threaded rods 51 away from the adjusting rod is connected to the structural plate, and the other end of the threaded rod 51 away from the adjusting rod is connected to the ceiling 6; the adjusting rod includes a rod body 52 and nuts 53 disposed at both ends of the rod body 52 and corresponding to the two sets of threaded rods; the axis of the rod body 52 and the axis of the nuts 53 are parallel to each other; the thread directions of the two sets of threaded rods are opposite; the rod body 52 includes at least two sets of connecting rods 521 of equal length and arranged in parallel, and fasteners 522 for fixing the two sets of connecting rods 521.

[0033] The threaded rod 51 is made of round steel with a diameter of 10mm. One end is bent into a hook to hook onto the lifting ring 1, and it is connected to the nut 53 on the adjusting rod through its threads. The rod body 52 is composed of at least two round steel rods with a diameter of 10mm arranged in parallel as connecting rods 521. Nuts 53 for connecting the threaded rods 51 are provided at both ends of the rod body 52. ​​The threads of the two sets of threaded rods 51 are in opposite directions. Therefore, by simply rotating the rod body 52, both sets of threaded rods 51 can be screwed in or out simultaneously, thereby adjusting the distance between the two sets of threaded rods 51 and thus the overall length of the adjustable lifting rod 5.

[0034] In actual use, since the rod body 52 is relatively long and the length of the adjustable rod 5 needs to be adjusted by applying torque to it, three round steel bars are reinforced by fasteners 522 every 200mm along the length to ensure its overall rigidity. Specifically, the fasteners 522 are ring-shaped and are connected to all the connecting rods 521 to form a whole.

[0035] The adjustable hanger 5 is generally located on the side near the drum assembly 4. When the extension length is determined, the length of the adjustable hanger 5 can be adjusted to further adjust the installation angle of the ceiling 6.

[0036] In some possible implementations, the suspension structure includes multiple sets of fixed pulley assemblies 2 respectively installed on the structural plate and the ceiling 6 close to each other, a rope 3 with one end connected to the structural plate and the other end passing through the multiple sets of fixed pulley assemblies 2 and connected to the structural plate, and a drum assembly 4 connected to the structural plate with one end of the rope 3 and used for winding and unwinding the rope 3.

[0037] Furthermore, the fixed pulley assembly 2 includes a wheel 21, axle 22, pulley bracket 23, and pulley hook 24; the wheel 21 is mounted on the axle 22, the pulley bracket 23 has a U-shaped structure, and the axle 22 is rotatably mounted inside the U-shaped structure; the pulley hook 24 is mounted on the top surface of the U-shaped structure and is rotatably engaged; the rotation axis of the pulley hook 24 is perpendicular to the axis of the axle 22.

[0038] The axle 22 connects the wheel 21 to the pulley bracket 23, enabling the wheel 21 to rotate with the pulley bracket 23. The pulley bracket 23 is made of steel plate cut and bent to form a U-shaped structure, with openings on both sides to connect to the axle 22. The axle 22 is located inside the U-shaped structure, and the opening at the top of the U-shaped structure is used to connect to the pulley hook 24. The pulley hook 24 is made of 10mm diameter round steel bent into a straight section and a hook-shaped section. One end of the straight section is rotatably connected to the top of the U-shaped structure, thereby enabling the fixed pulley assembly 2 to rotate with the structural plate and the ceiling 6. The other end of the straight section is connected to the hook-shaped section, which is then hooked to the lifting ring.

[0039] The fixed pulley assembly 2 is attached to the lifting ring 1 via the pulley hook 24. The rotational cooperation between the pulley bracket 23 and the pulley hook 24 allows the pulley and the lifting ring 1 to smoothly transmit force in different directions.

[0040] The fixed pulley assembly 2 on the ceiling 6 and the fixed pulley assembly 2 on the structural plate are staggered and located on the same vertical plane;

[0041] The rope 3 has a diameter of 10mm and passes sequentially through the fixed pulley assembly 2 on the structural plate and the ceiling 6, connecting all the connection points together, thereby pulling the ceiling 6 onto the structural plate. One end of the rope 3 is fixed to a corresponding set of lifting rings 1 by rope clips 31, and the other end is hooked to the corresponding lifting ring 1 by the drum assembly 4.

[0042] In some possible implementations, the drum assembly 4 includes a drum support 45 rotatably connected to the structural plate, a drum 41 rotatably mounted on the drum support 45 and connected to one end of the rope 3, and a ratchet mechanism mounted on the drum support 45 and used in conjunction with the drum 41.

[0043] In some possible implementations, a guide wheel 42 is provided on the drum support 45 and rotates with the drum support 45. The axis of the guide wheel 42 is parallel to the axis of the drum 41. The guide wheel 42 is located below the drum 41. One end of the rope 3 passes through the guide wheel 42 and is connected to the drum 41.

[0044] The drum assembly 4 comprises a drum 41, a guide wheel 42, a rotating shaft 43, a ratchet mechanism, a drum bracket 45, and a drum hook 46. The drum 41 is used to wind up and unwind the rope 3. The guide wheel 42 guides the rope 3 to prevent the drum assembly 4 from tilting and being damaged under uneven tension, ensuring the stability of the entire device. The rotating shaft 43 mounts the drum 41 and the guide wheel 42 on the drum bracket 45, enabling rotational engagement between the guide wheel 42 and the drum 41. The ratchet 44 is coaxially connected to the drum 41, and can brake the drum 41 to control the total length of the rope 3 in the ceiling 6 hoisting structure. The drum hook 46 is rotatably connected to the drum bracket 45, and the drum hook 46 forms a rotatable connection with the lifting ring 1 to achieve rotational connection with the structural plate. The structure of the drum hook 46 is the same as that of the pulley hook 24, and the drum bracket 45 also has a U-shaped structure.

[0045] The pulley hook 24 and pulley bracket 23, and the drum hook 46 and drum bracket 45 are all rotatably connected, which ensures the directness of force transmission even when the installation direction of the lifting ring 1 is deviated, and prevents torsional force from being generated on the pulley bracket 23 and the drum bracket 45, thus making the installation of the lifting ring 1 more tolerant.

[0046] In some possible implementations, both the fixed pulley assembly 2 and the guide wheel 42 are V-shaped pulleys, thereby guiding the rope 3 and preventing it from detaching from the fixed pulley assembly 2 or the guide wheel 42.

[0047] In some possible implementations, the ratchet mechanism includes a ratchet 44 coaxially connected to the drum 41 and a pawl 47 rotatably mounted on a bracket and engaged with the ratchet 44.

[0048] Ratchet 44 is mounted on shaft 43 and located outside drum support 45, and pawl 47 is located on the same side of ratchet 44. When drum 41 rotates to screw rope 3 in or out, ratchet 44 follows. When the specified length of rope 3 is reached, drum 41 stops rotating. At this time, the rotation of drum 41 is limited by the cooperation of pawl 47 and ratchet 44. A support rod is provided on the outside of drum support 45. The axis of the support rod is parallel to the axis of drum 41. Pawl 47 is fitted on the outside of the support rod and rotates with the support rod.

[0049] This utility model, through the cooperation of rope 3 and fixed pulley assembly, allows the hanging points of the structural plate and ceiling 6 to be flexibly arranged without being restricted by special structural conditions. At the same time, the length of rope 3 between each point is automatically balanced by the structural system based on the characteristic that the tension on both sides of the pulley is equal, avoiding the problem of calculating and processing the length of the hanging rod, and greatly reducing the installation difficulty of the ceiling 6.

[0050] In addition, based on the principle that the internal tension of the rope 3 connected to the pulley 2 is the same, the force at each connection point of the ceiling 6 can be relatively uniform, reducing internal stress concentration, preventing cracking and deformation, and ensuring installation quality and safety of use.

[0051] By rotating the drum 41 and adjusting the length of the adjustable rod 5, the height and angle of the ceiling 6 can be adjusted, improving the convenience of ceiling 6 installation and positioning and its maintainability; finally, it can be fixed to the structural plate by fixing the truss.

[0052] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
