[0001] The utility model relates to the technical field of suspended ceiling anti-support structures, in particular to an anti-suspended ceiling support structure. Background Art

[0002] Nowadays, in general ceiling support structures, the counter-support is generally connected to the main keel. During the ceiling decoration operation, the installation of the keel is very troublesome. It not only needs to be connected and fixed with the hanger, but also needs to be connected with the counter-support. At the same time, the connection between the keel, the hanger and the counter-support is complex in structure, which is troublesome when disassembly is required. In addition, the hanger and the counter-support are installed on the roof, and it is also troublesome when they need to be moved.

[0003] A Chinese patent with publication number CN220908866U discloses an inverted ceiling support structure, including a slide rail and a hanger, wherein a roof is arranged at the upper end of the slide rail, wherein a protruding block is arranged inside the slide rail, a hanger is arranged at the lower end of the slide rail, an upper connector is arranged at the upper end of the hanger, grooves are arranged on both sides of the upper end of the upper connector, wherein the upper connector is arranged in the slide rail, and the groove is stuck on the protruding block, a hollow chamber is arranged inside the upper connector, a threaded barrel is arranged in the hollow chamber, wherein the threaded barrel is threadedly connected to the hanger, a sleeve is arranged in the middle of the hanger, wherein the sleeve is sleeved on the hanger, positioning bolts are arranged at both ends of the sleeve, and a lower connector is arranged at the lower end of the hanger.

[0004] The above-mentioned prior art solutions have the following defects: the verticality of the traditional inverted ceiling support structure is difficult to ensure during the installation process, which may cause the ceiling to deform when the air pressure changes, forming a dome, thereby destroying the ceiling.

[0005] To this end, we proposed an anti-ceiling support structure to solve the above problems. Utility Model Content

[0006] The utility model aims to provide an inverted ceiling supporting structure to solve the problem of difficulty in ensuring verticality in the above-mentioned background technology.

[0010] Preferably, there are two groups of T-shaped screws, each group has two, which are respectively arranged at the connection between the main keel and the secondary keel to ensure that the connection between the main keel and the secondary keel is firm and reliable. Through the threaded connection of the T-shaped screws, a tight fit between the fasteners can be achieved to prevent the ceiling structure from loosening or falling off during use.

[0011] Preferably, there are four supporting hangers, which are respectively fixedly connected to the front and rear ends of the lower surfaces of the two secondary keels, thereby enhancing the overall supporting force of the suspended ceiling structure. By increasing the number of supporting hangers and arranging them reasonably, it can be ensured that the suspended ceiling structure can be evenly stressed when bearing loads, reducing local stress concentration, and improving the bearing capacity and service life of the suspended ceiling structure.

[0012] Preferably, there are two groups of fastening blocks, each group has two, which are respectively arranged between the secondary keel and the second main keel, thereby strengthening the connection between the secondary keel and the second main keel.

[0015] 1. The inverted ceiling support structure is provided with two angle steel oblique supports, which are located at the front and back between the floor slab and the main keel. This symmetrical design can effectively ensure the verticality of the ceiling structure. The angle steel oblique supports not only provide additional support, but also ensure that the ceiling structure can be supported evenly on the front and back, thereby reducing deformation or damage caused by uneven force, and further ensuring the verticality of the ceiling structure.

[0016] 2. The inverted ceiling support structure, the supporting hanger 2 is connected to the lower surface of the secondary keel, forming a stable support structure, which can ensure that the ceiling structure can be evenly stressed when bearing loads, reduce local stress concentration, and thus maintain the verticality of the ceiling structure.

[0017] 3. The inverted ceiling support structure is provided with a fastening block between the second main keel and the secondary keel, and connected by bolt 2, which strengthens the integrity and stability of the ceiling structure. The fastening block acts like an additional support point, which can further ensure the verticality of the ceiling structure. BRIEF DESCRIPTION OF THE DRAWINGS
