It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope requested by the utility model.

[0020] As Figures 1-4 Shown, a kind of ceiling joist mounting structure, including hanger rod 2 and the hanger piece installed in the lower end of hanger rod 2, C-shaped joist 8 is installed inside the hanger piece, the present technical solution can disperse the force that C-shaped joist 8 applies to hanger piece, reduce the concentrated load that C-shaped joist 8 applies to hanger piece, to reduce the concentrated load that hanger piece is subjected to too big and lead to the phenomenon of hanger piece damage.

[0021] As Figures 1-3As shown, the hanging piece comprises a first vertical plate 1, the upper end of the first vertical plate 1 is fixedly connected with the lower end of a boom 2, as a preferred connection mode, a top connecting plate 19 is fixedly connected with the upper end of the first vertical plate 1, a through hole is formed in the inside of the top connecting plate 19, the boom 2 is inserted into the inside of the through hole, and two hexagonal nuts 3 are threadedly connected with the outside of the boom 2 and are respectively located on the upper and lower sides of the top connecting plate 19, at this time, by rotating the hexagonal nuts 3, the height of the top connecting plate 19 on the outside of the boom 2 can be adjusted, so that the height of the hanging piece is adjusted.

[0022] The lower end of the first vertical plate 1 is fixedly connected with a bottom plate 18, one end of the bottom plate 18 is fixedly connected with a second side plate 16, a first movable slot 4 is formed in the inside of the first vertical plate 1, a first lead screw 5 is inserted into the inside of the first movable slot 4, and two first nuts 6 are threadedly connected with the outside of the first lead screw 5 and are respectively located on the two sides of the first vertical plate 1, at this time, the C-shaped keel 8 is placed in the combined structure of the first vertical plate 1, the bottom plate 18 and the second side plate 16, and the first lead screw 5 is located in the inside of the C-shaped keel 8, then the first nut 6 located on the inside of the first vertical plate 1 is rotated, so that the first lead screw 5 moves towards the C-shaped keel 8, until the first lead screw 5 abuts against the C-shaped keel 8, that is, the reinforcing force for reinforcing the C-shaped keel 8 is applied to the side surface of the C-shaped keel 8, at this time, the C-shaped keel 8 is supported from the lower side by the bottom plate 18 and is clamped and positioned by the first lead screw 5 and the second side plate 16, so that the downward load applied to the bottom plate 18 by the C-shaped keel 8 is reduced, and the phenomenon that the hanging piece is damaged due to excessive concentrated load is reduced.

[0023] After the position of the first lead screw 5 is adjusted, the other first nut 6 is rotated, so that the two first nuts 6 are clamped on the outside of the first vertical plate 1, and the first lead screw 5 is positioned more stably.

[0024] Meanwhile, as shown in Figures 1-2 and Figure 4 one end of the first lead screw 5 can be rotatably connected with an elastic extrusion ring 7, the elastic extrusion ring 7 is made of a metal material with elasticity, such as copper or steel, when the first lead screw 5 moves, the elastic extrusion ring 7 abuts against the C-shaped keel 8, at this time, the middle part of the elastic extrusion ring 7 is extruded, so that the upper end and the lower end of the elastic extrusion ring 7 respectively extend to the upper side and the lower side, so that the upper end and the lower end of the elastic extrusion ring 7 respectively abut against the inner walls on the upper and lower sides of the C-shaped keel 8, at this time, the C-shaped keel 8 is three-point positioned, and the load applied to the hanging piece by the C-shaped keel 8 is further dispersed.

[0025] The upper side and the lower side of the elastic extrusion ring 7 and the side of the elastic extrusion ring 7 away from the first lead screw 5 are all provided with extrusion plates 9, and the contact area of the elastic extrusion ring 7 and the C-shaped keel 8 is increased by the arrangement of the extrusion plates 9, so that the force is dispersed.

[0026] The extrusion plate 9 can be rotatably connected to the elastic extrusion ring 7 or directly fixedly connected to the elastic extrusion ring 7, and the extrusion plate 9 in the technical solution is preferably rotatably connected to the elastic extrusion ring 7, so that the extrusion plate 9 can be always arranged in parallel with the inner wall of the C-shaped keel 8.

[0027] As shown in Figures 1-2 The outer side of the elastic extrusion ring 7 is fixedly connected with a guide rod 10, the guide rod 10 is slidably connected in the inner side of the first movable slot 4, and the elastic extrusion ring 7 can be limited at two points by the first screw rod 5 and the guide rod 10, so that the elastic extrusion ring 7 can move on a plane and cannot rotate.

[0028] As shown in Figures 2-4 The outer side of the second side plate 16 is fixedly connected with a second screw rod 14, one side of the second side plate 16 is provided with a movable side plate 11, the inner side of the movable side plate 11 is provided with a second movable slot 13, the movable side plate 11 is slidably connected to the outer side of the second screw rod 14 through the second movable slot 13, and the upper end of the movable side plate 11 is fixedly connected with a top positioning plate 12. Figure 4 At this time, as shown in The outer side of the second screw rod 14 is threadedly connected with a second nut 15 for positioning the movable side plate 11 after movement.

[0029] Meanwhile, the outer side of the second side plate 16 is fixedly connected with a guide block 17, the guide block 17 is slidably connected with the second movable slot 13, and the guide block 17 can guide the movable side plate 11 to move vertically and cannot rotate.

[0030] The working principle of the utility model is as follows: in use, the C-shaped keel 8 is inserted into the combined structure of the first vertical plate 1, the bottom plate 18 and the second side plate 16, the side wall of the C-shaped keel 8 abuts against the second side plate 16, then the movable side plate 11 is slid to make the top positioning plate 12 abut against the upper side of the C-shaped keel 8, and the position of the top positioning plate 12 is locked by the second nut 15.

[0031]

[0032] Then, rotate the first nut 6 located inside the first vertical plate 1, so that the first lead screw 5 moves toward the C-shaped keel 8. When the first lead screw 5 moves, the elastic compression ring 7 abuts against the side wall of the C-shaped keel 8. At this time, the middle part of the elastic compression ring 7 is compressed, so that the upper and lower ends of the elastic compression ring 7 extend to the upper and lower sides respectively, so that the upper and lower ends of the elastic compression ring 7 abut against the inner walls of the upper and lower sides of the C-shaped keel 8 respectively. Then, the first lead screw 5 and the elastic compression ring 7 are locked by the first nut 6.

[0033] At this time, as Figure 4 As shown, the elastic compression ring 7 applies three-directional inner reinforcement forces F1, F2, and F3 to the C-shaped keel 8 from the inside, and the top positioning plate 12, the bottom plate 18, and the second side plate 16 apply three-directional outer reinforcement forces F4, F5, and F6 to the C-shaped keel 8 from the outside. The three inner reinforcement forces and the three outer reinforcement forces are one-to-one opposite, thereby maintaining the balance of inner and outer reinforcement and reducing the deformation of the C-shaped keel 8 during the reinforcement process.
