DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The following provides a foldable ceiling structure, which can be installed by transporting existing ceiling panels in a folded form and then unfolding them after transportation to the site, thereby reducing the installation steps and shortening the construction period.

[0030] Please refer to Figure 1 、 5 、6.

[0031] The ceiling structure includes: a hanger 1, a first ceiling panel 2, a second ceiling panel 3 and a hinge 4;

[0032] Two sides of the first ceiling panel 2 are connected to two second ceiling panels 3 via two hinges 4, so that the second ceiling panels 3 can be folded or unfolded relative to the first ceiling panel 2;

[0033] The sling 1 is fixedly connected to the upper floor slab, and the first ceiling panel 2 is suspended directly below the sling 1 . The distance between the first ceiling panel 2 and the upper floor slab is sufficient for the second ceiling panel 3 to be folded or unfolded.

[0034] After the construction workers use the hoist 1 to hang the first ceiling panel 2 at the construction site, they can unfold the second ceiling panel 3 to obtain a larger and complete ceiling structure without the need to separately connect the upper floor slab and the second ceiling panel 3, thereby reducing the assembly process and shortening the construction period of the ceiling.

[0035] The sling 1 can be an existing sling, for example, a combination of a screw rod, a keel and a hanging clamp.

[0036] Its connection structure (not shown in the figure) is: the screw rod is fixedly connected to the upper floor and hangs vertically, the keel is fixedly connected to the bottom end of the screw rod, the hanging clamp is fixedly connected to the first ceiling plate 2, and the hanging clamp is clamped to the keel.

[0037] The construction steps are: the hanging clip is pre-fixed and connected to the first ceiling panel 2, the second ceiling panel 3 is transported in a folded state, the screw rod is fixedly installed on the upper floor slab at the construction site, the keel is suspended using the screw rod, and then the second ceiling panel 3 is unfolded, and then the first ceiling panel 2 is mounted under the keel through the hanging clip.

[0038] For further information, please refer to Figure 1 .

[0039] Since the second ceiling panels 3 are rotatable, when the building vibrates, the second ceiling panels 3 rotate through the hinges 4, which may cause a gap between the two second ceiling panels 3 and cracks in the paint on the bottom surfaces of the second ceiling panels 3.

[0040] In order to solve this technical problem, it is necessary to prevent the second ceiling panel 3 from rotating.

[0041] Please refer to Figure 1In the enlarged view of the local structure, a strip connecting member 5 is installed between two adjacent first ceiling panels 2 and two adjacent second ceiling panels 3, and the strip connecting member 5 is snap-connected with the first ceiling panel 2 and the second ceiling panel 3.

[0042] After the second ceiling panels 3 are unfolded, there is no gap between the first ceiling panels 2 and the second ceiling panels 3 , and the gap between two adjacent first ceiling panels 2 and the gap between two adjacent second ceiling panels 3 are filled by the strip-shaped connecting pieces 5 .

[0043] The strip-shaped connecting piece 5 clamps two adjacent first ceiling panels 2 and two adjacent second ceiling panels 3, on the one hand filling the gap between the two adjacent first ceiling panels 2 and the second ceiling panels 3, on the other hand preventing the second ceiling panels 3 from rotating.

[0044] On the other hand, the strip-shaped connecting member 5 can adopt two different structures.

[0045] Structure 1: The strip-shaped connecting member 5 adopts a decorative strip. When the decorative strip connects two adjacent ceiling panels, the decorative strip and the ceiling panels are hung or clamped, and the decorative strip has no connection with the upper floor slab.

[0046] Structure 2: The strip connecting member 5 adopts a keel. When the keel connects two adjacent ceiling panels, the keel and the ceiling panels are hung or clamped, and the keel is fixed to the bottom of the upper floor panel through a screw rod. The keel not only fills the gap between the two adjacent upper floor panels, but also stabilizes the first ceiling panel and the second ceiling panel, making it difficult for the two to shake.

[0047] Preferably, the keel is fixedly connected to the upper floor slab via a hanger.

[0048] Since the first and second ceiling panels 2 and 3 are difficult to connect to the keel after the keel is fixed to the upper floor, it is also possible to consider using the keel and decorative strips alternately in the ceiling structure, that is, one side of the first ceiling panel 2 is connected to the keel, and the other side of the first ceiling panel 2 is connected to the decorative strip. This installation method is not only convenient for installation, but also can stabilize the first and second ceiling panels.

[0049] on the other hand:

[0050] The strip connecting member 5 can be a strip member with an I-shaped or π-shaped cross section, or other shapes that can be clamped and hung between the two first ceiling panels 2 or the two second ceiling panels 3 .

[0051] Preferably, a slot 31 is provided on a side of the second ceiling panel 3 away from the first ceiling panel 2 , and inserting strips 51 are provided on both sides of the strip-shaped connector 5 , and the inserting strips 51 are snap-connected or frictionally connected to the slot 31 .

[0052] In the accompanying drawings, anti-slip grooves 52 are formed on the upper and lower surfaces of the insertion strip 51. The anti-slip grooves 52 are used to increase the friction between the insertion strip 51 and the slot 31, so that the two are frictionally connected; the upper and lower surfaces of the insertion strip 51 can also be installed with outwardly protruding springs, and at the same time, inwardly recessed slots are formed inside the slot 31 to allow the two to be snapped together.

[0053] If the first ceiling panel 2 is installed on the upper floor slab via keels and buckles, the first ceiling panel 2 cannot be moved after installation, which makes it difficult for the strip connector 5 with the inserting strip 51 to be inserted between two adjacent second ceiling panels 3 .

[0054] In order to solve the above technical problems, it is necessary to improve the mobility of the first ceiling panel 2 so that it can move a certain distance in the horizontal direction.

[0055] Please refer to Figure 1 、 Figure 3 .

[0056] The sling 1 comprises a sling rod 11, a rigging fixture 12 and a cable 13;

[0057] The hanger 11 is fixedly connected to the upper floor slab, the rigging fixture 12 is connected to the bottom end of the hanger 11 , and the first ceiling panel 2 is connected to the rigging fixture 12 via a cable 13 . A plurality of cables 13 are evenly distributed around the axis of the hanger 11 .

[0058] The rigging fixture 12 and the boom 11 can be connected by threading, clamping or hanging.

[0059] Sometimes, the upper floor is blocked by the pipe and the hanger 11 cannot be directly fixed under the upper floor. At this time, a steel structure that bypasses the pipe can be installed between the upper floor and the hanger 11, and then the hanger 11 is connected to the steel structure.

[0060] One boom 11 and one rigging fixture 12 may be connected to one cable 13 or multiple cables 13 .

[0061] The rigging fixture 12 and the cable 13 constitute a flexible structure connecting the hanger 11 and the first ceiling panel 2, so that the first ceiling panel 2 can still move laterally and longitudinally after being hung on the upper floor, so that the two adjacent first ceiling panels 2 and the two adjacent second ceiling panels 3 can move away from each other in the horizontal direction, thereby providing a gap for the strip connector 5 to be inserted between the two.

[0062] Optionally, in order to make the height of the first ceiling panel 2 adjustable so that adjacent first ceiling panels 2 are at the same height, please refer to Figure 3 .

[0063] A second nut 14 is installed at the bottom end of the boom 11 , and the rigging fixture 12 is sleeved on the boom 11 . The rigging fixture 12 can slide vertically along the boom 11 and overlap the second nut 14 .

[0064] The height of the rigging fixture 12 can be adjusted by adjusting the height of the second nut 14 , thereby adjusting the height of the first ceiling panel 2 .

[0065] Alternatively, see Figure 4 .

[0066] The rigging fixture 12 includes: a threaded barrel 121 and a first nut 122;

[0067] The threaded barrel 121 is sleeved on the outside of the boom 11, and the outer circumferential surface of the threaded barrel 121 is provided with a thread. The first nut 122 and the threaded barrel 121 are spirally connected. The outer circumferential surface of the threaded barrel 121 is provided with multiple inwardly recessed openings 123, and each opening 123 is used to embed a cable 13. The top end of the cable 13 is connected to an anti-slip component 131, and the anti-slip component 131 abuts against the top wall of the threaded barrel 121.

[0068] Furthermore, connecting multiple cables 13 with a hanger 11 and a rigging fixture 12 can save costs, but the length of each cable 13 is difficult to produce and assemble to the same size, resulting in the first ceiling panel 2 being difficult to maintain a horizontal posture when connected to a hanger 11 through multiple cables 13, thereby causing angle and height errors between adjacent second ceiling panels 3.

[0069] In order to solve the above technical problems, after the first ceiling panel 2 is installed on the suspension rod 11 through the cable 13, the length of the cable 13 can still be adjusted, so as to level the first ceiling panel 2.

[0070] Please refer to Figure 2 、 3 .

[0071] The hinge 4 includes a first rotating portion 41, a second rotating portion 42 and a rotating shaft 43;

[0072] The first rotating part 41 is fixedly connected to the first ceiling panel 2, the second rotating part 42 is fixedly connected to the second ceiling panel 3, the rotating shaft 43 and the first rotating part 41 are connected by a threaded pair, the rotating shaft 43 and the second rotating part 42 are connected by a rotating pair, the bottom end of the cable 13 is fixedly connected to the rotating shaft 43 and is wound around the rotating shaft 43, and when the rotating shaft 43 rotates, the cable 13 is wound or unwound.

[0073] The rotating shaft 43 and the first rotating part 41 are connected by a threaded pair, so that the rotation of the rotating shaft 43 itself is restricted. When the second ceiling panel 3 rotates, the second ceiling panel 3 and the rotating shaft 43 slip, and the rotating shaft 43 does not rotate.

[0074] Please refer to Figure 6 When the first ceiling panel 2 is not leveled, the construction worker pushes the second ceiling panel 3 to flip it upward, thereby exposing the rotating shaft 43 between the first ceiling panel 2 and the second ceiling panel 3, and exposing an operating space for inserting a wrench to rotate the rotating shaft 43. When the construction worker uses the wrench to drive the rotating shaft 43 to rotate, the rotating shaft 43 is equivalent to a winch, and the rotation of the rotating shaft 43 is used to retract and extend the cable 13, thereby changing the length of the cable 13, and then leveling the first ceiling panel 2.

[0075] Optionally, a through hole 431 is provided on the rotating shaft 43 and passes through it radially. The bottom end of the cable 13 passes through the through hole 431 and is engaged with the rotating shaft 43. The other end of the cable 13 is wrapped around the rotating shaft 43 for several turns and then connected to the rigging fixture 12.

[0076] The bottom end of the cable 13 is tied to itself after passing through the through hole 431 , thereby preventing the cable 13 from being separated from the rotating shaft 43 .

[0077] Alternatively, the bottom end of the cable 13 is also connected to an anti-slip component, which is not shown in the figure. The size of the anti-slip component is larger than the aperture of the through hole 431, thereby preventing the cable 13 from separating from the rotating shaft 43.

[0078] Optionally, a polygonal column 432 is provided at one end of the rotating shaft 43. The construction worker rotates the polygonal column 432 with a wrench to drive the rotating shaft 43 to rotate.

[0079] Optionally, the other end of the rotating shaft 43 is threaded and mounted with a third nut 44. When the third nut 44 is tightened, it abuts against the first rotating portion 41. The third nut 44 is used for frictional connection with the first rotating portion 41. Before the third nut 44 is loosened, the third nut 44 is used to prevent the rotating shaft 43 from rotating in the absence of external force.

[0080] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the embodiments of the present invention.
