[0003] In the prior art, the common internal structure of suspended ceilings is becoming more and more complicated, and the height of suspended ceilings is becoming lower and lower, which makes the length of the hanger exceed 1.5m; since the length of the hanger is too long, it is very easy to shake during the construction of the suspended ceiling, and therefore it is necessary to set an anti-support structure inside the suspended ceiling, so that the anti-support structure is connected to the hanger, so as to enhance the structural strength of the hanger relative to the floor slab and the hanger relative to the suspended ceiling, and finally achieve the technical purpose of stabilizing the suspended ceiling structure.

[0004] The inventors discovered that the length of the hanger in the prior art is not adjustable, and the hanger needs to be cut when constructing suspended ceilings of different heights; however, after cutting the hanger, the connection between the counter-support structure and the hanger cannot be guaranteed, and it is even easy for the counter-support structure to fail to be loaded, resulting in technical defects such as reduced efficiency of suspended ceiling construction and reduced stability of the suspended ceiling structure.

[0044] Please also read Figures 1 to 8 The suspended ceiling counter-support structure provided by the present application is now described. The suspended ceiling counter-support structure provided by the present application comprises a fixing member 1, two supporting arms 2, two sets of locking structures 3 and an adjusting component 4.

[0045] The fixing member 1 is used to be arranged between the floor and the ceiling, and its axial direction is parallel to the up-down direction.

[0046] The two support arms 2 are arranged side by side on the fixing member 1 along the up-down direction, and their axial directions are parallel to the up-down direction, and they are both slidably connected with the fixing member 1 along the up-down direction.

[0047] The two sets of locking structures 3 correspond to the two support arms 2 one by one; wherein each set of locking structures 3 is used to connect the corresponding support arm 2 and the fixing member 1 to limit the movement of the support arm 2 relative to the fixing member 1.

[0048] The adjustment component 4 is disposed on the fixing member 1 and is connected to the two support arms 2 to drive the two support arms 2 to move relative to the fixing member 1 .

[0049] In actual use, the upper end of the support arm 2 on the upper side is used to connect with the floor slab, and the lower end of the support arm 2 on the lower side is used to connect with the ceiling.

[0050] In the embodiment of the present application, the two support arms 2 can be driven by the adjustment component 4 to move simultaneously relative to the fixing member 1, so that the two support arms 2 can respectively abut against the floor and the ceiling; on this basis, the positions of the two support arms 2 are respectively limited by two sets of locking structures 3, so as to lock the combined length of the support arms 2 and the fixing member 1.

[0051] Compared with the prior art, the suspended ceiling counter-support structure provided in this embodiment can be adapted to suspended ceilings of different heights, and can effectively improve the structural stability of the suspended ceiling, while ensuring the stability of the suspended ceiling construction efficiency.

[0052] In some embodiments, Figure 3 and Figure 7 As shown, guide grooves 11 are provided at both upper and lower ends of the fixing member 1 , and the two support arms 2 are slidably inserted into the two guide grooves 11 respectively to achieve a sliding connection relationship between the fixing member 1 and the support arms 2 .

[0053] In some embodiments, Figure 1 and Figure 7 As shown, each guide groove 11 has a strip hole 12 on its inner wall, and each strip hole 12 passes through to the outer side surface of the fixing member 1 along the horizontal direction.

[0054] On this basis, each support arm 2 has a slider 21 suitable for slidingly engaging in the corresponding strip hole 12; since the strip hole 12 extends in the up and down directions, the combination of the slider 21 and the strip hole 12 can effectively limit the sliding direction of the support arm 2 relative to the fixing member 1.

[0055] In some embodiments, Figure 7 As shown, the locking structure 3 includes a positioning hole 31 , a plurality of alignment holes 32 and a stop rod 33 .

[0056] The positioning hole 31 passes through the fixing member 1 in the horizontal direction and is communicated with the guide groove 11 .

[0057] A plurality of alignment holes 32 are arranged at intervals along the up-down direction on the corresponding support arm 2 , and each alignment hole 32 is suitable for being coaxially connected to the positioning hole 31 .

[0058] The stop rod 33 is adapted to be inserted into the mutually communicating alignment hole 32 and positioning hole 31 to limit the movement of the support arm 2 relative to the fixing member 1 .

[0059] By adopting the above technical solution, when the alignment hole 32 and the positioning hole 31 are connected to each other, the stop rod 33 is in a horizontal state, so it will not fall off the positioning hole 31, thereby improving the connection structure strength between the fixing member 1 and the support arm 2.

[0060] In some embodiments, Figure 7 As shown, both ends of the stop rod 33 have elastic plugs 331 .

[0061] When the stop rod 33 needs to be inserted into the interconnected alignment hole 32 and positioning hole 31, one of the elastic plugs 331 will undergo elastic deformation to be inserted into the alignment hole 32; finally, both elastic plugs 331 abut against the outer side surface of the fixing member 1 to limit the relative movement between the fixing member 1 and the support arm 2.

[0062] In some embodiments, Figure 1 and Figure 3 As shown, the adjustment assembly 4 includes a double-start screw 41 and two translation members 42 .

[0063] The double-headed screw 41 is arranged on the fixing member 1, its axial direction is parallel to the left-right direction, and it is located between the two support arms 2; in the present embodiment, the double-headed screw 41 is connected to the fixing member 1 for rotation along the left-right direction, and it has two threaded portions which are respectively located on both sides of the fixing member 1 and have opposite thread directions.

[0064] The two translation members 42 are respectively arranged at the two ends of the double-headed screw rod 41, and are fixedly connected with a transmission nut 421 suitable for being threadedly connected with the threaded portion.

[0065] In this embodiment, the upper and lower ends of each translation member 42 are hinged with connecting rods 5 , and the swing ends of the two connecting rods 5 are hinged to the two support arms 2 respectively.

[0066] In some embodiments, Figure 3 and Figure 8 As shown, the translation member 42 has a reserved groove 422 suitable for the driving nut 421 to be embedded, and the bottom of the reserved groove 422 has a reserved hole 423 that penetrates the translation member 42 and is suitable for the double-headed screw 41 to be inserted.

[0067] During actual assembly, the end of the double-headed screw 41 is adapted to pass through the reserved hole 423 and extend outward, and the extended end has a hand-screw portion 411 extending radially outward and having a polygonal cross section, so as to facilitate manual control. In addition, the hand-screw portion 411 and the double-headed screw 41 are detachably connected to facilitate the removal of the double-headed screw 41, thereby optimizing the repair and maintenance of related components.

[0068] In some embodiments, Figure 6 As shown, the lower end of the support arm 2 on the lower side has a connecting screw 6 extending downward for passing through the ceiling and extending out, and the connecting screw 6 has a supporting nut 61 for abutting against the lower side of the ceiling.

[0069] In some embodiments, Figure 4 and Figure 5 As shown, the upper end of the support arm 2 on the upper side is fixedly connected to a hinge seat 7; a swing arm 8 is hinged on the hinge seat 7 along the horizontal direction, and the swing end of the swing arm 8 is hinged to a connecting seat 9 for connecting to the lower side of the floor slab.

[0070] By adopting the above technical solution, the connecting seat 9 can increase the contact area between the upper end of the support arm 2 and the floor, and at the same time, the support arm 2 connected to the floor can be adjusted up and down to adapt to ceilings of different heights.

[0071] It should be noted that, in the present embodiment, there are two articulated seats 7 which are symmetrically arranged; and, each articulated seat 7 has two swing arms 8 to increase the aforementioned contact area as much as possible, thereby ensuring the corresponding beneficial effects; at the same time, the two articulated seats 7 are connected via a connecting seat 9 to ensure the connection strength between the articulated seat 7 and the support arm 2.

[0072] Based on the same inventive concept, an embodiment of the present application also provides a prefabricated suspended ceiling, comprising any of the suspended ceiling counter-support structures proposed in the foregoing items.

[0073] The beneficial effects of the prefabricated suspended ceiling provided in this embodiment are the same as the beneficial effects of the aforementioned suspended ceiling counter-support structure, which will not be repeated here.

[0074] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
