In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0032] As shown in Figures 1 to 3 The utility model provides a kind of ceiling conversion layer steel frame unit, which comprises connecting assembly 1, hanger and keel 3, connecting assembly 1 includes chemical anchor bolt 11;Hanger includes multiple first square steel pipe 2, multiple first square steel pipe 2 are connected to beam or floor by chemical anchor bolt 11;Keel 3 includes several second square steel pipe 31, the both ends of each second square steel pipe 31 are connected to different first square steel pipe 2 respectively, and second square steel pipe 31 and first square steel pipe 2 are enclosed to form plane closed polygon structure, and second square steel pipe 31 is used to connect the suspender of ceiling.In the present embodiment, since the first square steel pipe 2 of hanger is connected to floor or beam by chemical anchor bolt 11, it is simple in structure, convenient to construct, and compared with ordinary expansion bolt, chemical anchor bolt 11 is widely used and has strong bearing capacity, which can ensure the structural stability of the ceiling conversion layer steel frame unit and the lower ceiling;Keel 3 includes several second square steel pipe 31, since the both ends of each second square steel pipe 31 are connected to different first square steel pipe 2, and second square steel pipe 31 and first square steel pipe 2 are enclosed to form plane closed polygon structure, therefore second square steel pipe 31 can be connected to first square steel pipe 2, further fix hanger, improve the shear level of the ceiling conversion layer steel frame unit;Since hanger adopts first square steel pipe 2, and keel 3 adopts second square steel pipe 31, compared with common angle steel and flat steel, the cross-sectional area of square steel pipe is larger, which has stronger compression resistance and bending resistance, further improving the structural strength and structural stability of the ceiling conversion layer steel frame unit.

[0033] Chemical anchor 11 is a high-strength anchor type commonly used in the art, which includes two parts of a chemical agent bottle and a screw rod. In use, the chemical agent bottle is first inserted into the drilled hole, and then the screw rod is rotated into the drilled hole using an electric drill to crush the chemical agent bottle. After the overflowed agent solidifies, the anchoring of the screw rod is completed.

[0034] Specifically, as shown in Figure 1 and Figure 2 , the connecting assembly 1 further comprises a lifting point steel plate 12 and a first nut 13. The lifting point steel plate 12 is attached to the beam or floor, and the first square steel pipe 2 is connected to the lifting point steel plate 12. The lifting point steel plate 12 has mounting holes formed therein. One end of the chemical anchor 11 is anchored to the beam or floor, and the other end of the chemical anchor 11 passes through the mounting hole and is threadedly connected with the first nut 13, which abuts against the lifting point steel plate 12. In this embodiment, the first square steel pipe 2 is connected to the lifting point steel plate 12 by three-sided welding, and the length of the first square steel pipe 2 connected to the lifting point steel plate 12 is not less than 290 mm. The lifting point steel plate 12 has a plurality of mounting holes corresponding to the plurality of chemical anchors 11. The lifting point steel plate 12 is placed against the beam or floor with the chemical anchors 11 passing through the mounting holes. Then the first nut 13 is screwed onto the end of the chemical anchor 11, thereby fixing the lifting point steel plate 12 to the beam or floor. The lifting point steel plate 12 is connected to the beam or floor by the plurality of chemical anchors 11, thereby achieving the fixation of the first square steel pipe 2. Meanwhile, the lifting point steel plate 12 increases the connection area of the first square steel pipe 2 with the beam or floor, thereby improving the stability of the connection.

[0035] To further improve the connection strength of the first square steel pipe 2 with the beam or floor, as shown in Figure 1 , the connecting assembly 1 further comprises a second nut 14, which is threadedly connected to the chemical anchor 11 and abuts against the first nut 13, thereby forming a double-nut structure on the screw rod of the chemical anchor 11. The two nuts interact with each other to generate a pressure, thereby forming a friction force that prevents the loosening of the two nuts.

[0036] As shown in Figure 1 and Figure 2 , the connecting assembly 1 further comprises a gasket 15, which is clamped between the first nut 13 and the lifting point steel plate 12. The gasket 15 can increase the contact area between the first nut 13 and the lifting point steel plate 12, thereby dispersing the pressure and friction force, and making the fastening force between the first nut 13 and the lifting point steel plate 12 more stable. It can be understood that after the installation of the chemical anchor 11 is completed, the construction personnel first place the lifting point steel plate 12 on the chemical anchor 11 through the mounting hole, then place the gasket 15 on the screw rod of the chemical anchor 11 and abut against the lifting point steel plate 12, and then successively screw and tighten the first nut 13 and the second nut 14 on the screw rod of the chemical anchor 11, thereby completing the fixation of the first square steel pipe 2.

[0037] like Figures 1 to 3 As shown, the first square steel pipe 2 is set perpendicular to the floor slab, and the second square steel pipe 31 is set perpendicular to the first square steel pipe 2. The second square steel pipe 31 and the first square steel pipe 2 form a rectangle. Specifically, the direction of the first square steel pipe 2 is vertical, and the direction of the second square steel pipe 31 is horizontal. The second square steel pipe 31 is vertically connected to the first square steel pipe 2 by full welding. The first square steel pipe 2 forms the four corners of the rectangle. The rectangular structure facilitates the connection of the suspension rods of the ceiling below, thereby reducing the difficulty of subsequent ceiling construction.

[0038] To further improve the structural strength and stability of the keel 3 itself, such as Figure 3 As shown, the keel 3 also includes a third-party steel pipe 32, wherein a third-party steel pipe 32 is provided between two opposing second square steel pipes 31. In this embodiment, the first square steel pipe 2, the second square steel pipe 31, and the third-party steel pipe 32 are all square steel pipes commonly used in the art, and the specific dimensions and specifications can be selected according to the actual conditions of the construction site.

[0039] Specifically, the second steel pipe 31 is welded to the third steel pipe 32, thereby ensuring the connection strength and stability of the two.

[0040] Furthermore, the ceiling transfer layer steel frame unit also includes diagonal braces, one end of which is connected to the first square steel pipe 2, and the other end of which is connected to the beam or floor slab. The diagonal braces can provide additional support and connection for the hangers, thereby improving the load-bearing capacity of the ceiling transfer layer steel frame unit. In addition, the diagonal braces form a stable triangular structure with the hangers, beams or floor slabs, which further improves the structural stability of the ceiling transfer layer steel frame unit.

[0041] This embodiment also provides a ceiling transition layer, which includes connecting rods and several of the aforementioned ceiling transition layer steel frame units. In two adjacent ceiling transition layer steel frame units, one end of the connecting rod is connected to the first square steel pipe 2 of one of the ceiling transition layer steel frame units, and the other end of the connecting rod is connected to the first square steel pipe 2 of the other ceiling transition layer steel frame unit. Specifically, when it is necessary to connect two ceiling transition layer steel frame units, the two ends of a connecting rod are respectively welded to the first square steel pipe 2 on the same side of the two ceiling transition layer steel frame units, and then the two ends of a second connecting rod are respectively welded to the first square steel pipe 2 on the other side of the two ceiling transition layer steel frame units, thereby realizing the connection of the two ceiling transition layer steel frame units.

[0042] In the embodiment, two adjacent suspended ceiling transfer floor steel frame units are connected by connecting rods to form an integral structure, so as to install the lower suspended ceiling.
