[0018] The preferred embodiments of the present application are described below in combination with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. EMBODIMENT

[0019] As Figures 1-4As shown, a Z-shaped light steel keel for a special-shaped suspended ceiling, comprising a main keel 1, a secondary keel 2 and a hanging pipe 3, the secondary keel 2 is connected to the main keel 1 through the hanging pipe 3, a light steel pipe 4 is inserted and fixed at the bottom end of the hanging pipe 3, L-shaped hangers 5 are fixed on the inner walls of the two sides of the secondary keel 2, an inner hanging groove 6 is formed on the longitudinal plate of the L-shaped hanger 5, a side sliding groove 7 is formed on one side of the bottom of the inner hanging groove 6, side plates 8 are welded and fixed on the bottom of the two sides of the hanging pipe 3, a lead screw one 9 and a lead screw two 10 are respectively threadedly connected on the two side plates 8, a sleeve 11 is welded and fixed at one end of the bottom of the main keel 1, and the hanging pipe 3 is inserted in the sleeve 11, thereby forming a Z-shaped light steel keel structure of the special-shaped suspended ceiling, which is convenient and fast to connect and construct, and can quickly and accurately adjust the inclination angle of the secondary keel 2 and fix the position, thereby meeting the construction requirements of the special-shaped suspended ceiling.

[0020] In the embodiment, the hanging pipe 3 and the sleeve 11 are fixed through two rivets 12, which is convenient for on-site cutting and rapid connection.

[0021] In the embodiment, the main keel 1 and the secondary keel 2 are C-shaped keels, which are convenient for installing the main keel 1 on the ceiling by using expansion wires or anchor rods, and are also convenient for fixing the plasterboard on the secondary keel 2.

[0022] In the embodiment, the hanging pipe 3 is a galvanized square tube, which is low in price and light in quality, and is suitable for suspended ceiling construction.

[0023] In the embodiment, the light steel pipe 4 can be put into the inner hanging groove 6, which is convenient for rapid connection and fixation by using the rivet 12.

[0024] The principle and advantages of the utility model are as follows: when the Z-shaped light steel keel structure for the special-shaped suspended ceiling is used, as shown, Figure 1 first, the main keel 1 is placed on the ceiling, then one end of the hanging pipe 3 is inserted into the sleeve 11, and the rivet 12 is punched to connect and fix the two, then the secondary keel 2 is held horizontally, the L-shaped hanger 5 is located below the light steel pipe 4, then the secondary keel 2 is transversely moved, as shown, Figure 3 the light steel pipe 4 is slid into the inner hanging groove 6 through the side sliding groove 7, then the lead screw one 9 and the lead screw two 10 are respectively rotated downward, so that the bottom ends of the two are placed on the inner side of the bottom of the secondary keel 2, thereby the secondary keel 2 is pressed and fixed on the hanging pipe 3, when the inclination angle of the secondary keel 2 is adjusted, as shown, Figure 2As shown, first rotate screw 9 upwards, then rotate screw 10 downwards. Use screw 10 to press down on the secondary keel 2, thereby adjusting its tilt angle. After determining the tilt angle, rotate screw 9 downwards again, so that its bottom end also presses on the secondary keel 2. Thus, screw 9 and screw 10 work together to compress and fix the tilted secondary keel 2. The Z-shaped light steel keel with this structural design is convenient for quick connection and construction, and can also quickly and accurately adjust the tilt angle of the secondary keel 2 and fix it firmly, thereby meeting the construction needs of irregular ceilings and improving practicality.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
