[0039] On the basis of Embodiment 1, a positioning screw 16 is provided to facilitate the connection between the upper connecting piece 1 and the auxiliary support piece 4. The steel structure reinforcing rib plate 2 is fixedly connected to the side surface of the upper connecting piece 1. The positioning screw 16 is arranged on the side surface of the upper connecting piece 1. A limiting nut 17 is screwed on the surface of the positioning screw 16. The upper connecting piece 1 is integrally in a square plate-like structure. A positioning plate 18 is arranged on the side surface of the auxiliary support piece 4. A through hole is opened on the side surface of the positioning plate 18. The positioning plate 18 is sleeved on the positioning screw 16 by using the through hole. The positioning card plate 6 is integrally in an "L"-shaped plate-like structure. The auxiliary support piece 4 is integrally in an "L"-shaped plate-like structure. A lower connecting piece 19 is arranged on the side surface of the auxiliary support piece 4. The lower connecting piece 19 is placed on the surface of the positioning card plate 6. The lower connecting piece 19 is welded and fixed to the side surface of the auxiliary support piece 4. Two groups of limiting ports 5 are opened, and both groups of limiting ports 5 are opened on the side surface of the auxiliary support piece 4;

[0040] During use, first, the positioning plate 18 is sleeved on the positioning screw 16, and then the limiting nut 17 is screwed on the positioning screw 16 for fastening, so that the auxiliary support piece 4 can be fixed to the side surface of the upper connecting piece 1. Subsequently, it can be fixed stably by welding, and the fixing stability of the auxiliary support piece 4 is further improved through the cooperation of the positioning screw 16 and the positioning plate 18. Then, after the auxiliary support piece 4 is installed, the lower connecting piece 19 is fixed to the side surface of the auxiliary support piece 4 to increase the installation stability of multiple groups of auxiliary support pieces 4. The compressive capacity of the auxiliary support piece 4 is improved through the lower connecting piece 19. When installing the lower connecting piece 19, the lower connecting piece 19 can be directly placed on the positioning card plate 6 for stability first, and then it can be directly welded. The support of the positioning card plate 6 also facilitates the subsequent fixing of the lower connecting piece 19 by the staff.

[0041] In order to fix the auxiliary support member 4 to the vertical connecting member 7, a positioning bolt 8 is provided. A gasket 20 and a limit block 21 are sleeved on the surface of the positioning bolt 8. The positioning bolt 8 is inserted into the limit port 5 and passes through the vertical connecting member 7. A positioning nut 22 is screwed on the positioning bolt 8. A limit groove 23 is formed on the surface of the limit block 21. A fixing screw 24 is arranged on the surface of the limit groove 23. A moving plate 25 is sleeved on the surface of the fixing screw 24. The moving plate 25 is in a square plate structure. The moving plate 25 can move up and down in the limit groove 23. The gasket 20 and the limit block 21 are movably connected on the positioning bolt 8. An auxiliary nut 26 is screwed on the fixing screw 24. The auxiliary nut 26 is located above the moving plate 25. A limit clamping plate 27 is arranged at the bottom of the moving plate 25. The limit clamping plate 27 is in an overall square plate structure. A chamfer is formed on the side surface of the limit clamping plate 27;

[0042] During use, first, the gasket 20 is sleeved on the positioning bolt 8, and then the positioning bolt 8 can pass through the auxiliary support member 4 and the vertical connecting member 7. Then, the limit block 21 is sleeved on the positioning bolt 8, and thus the positioning nut 22 can be screwed on the positioning bolt 8. By rotating the positioning nut 22, the moving plate 25 can be pulled up, and then the positioning nut 22 can be tightened. After the tightening is appropriate, the moving plate 25 is released, and then the limit clamping plate 27 can abut against the outer side surface of the positioning nut 22. The auxiliary nut 26 can be tightened to fix the moving plate 25, so as to cooperate with the limit clamping plate 27 to fix the positioning nut 22, avoiding the loosening problem of the positioning nut 22 and thus affecting the connection stability between the auxiliary support member 4 and the vertical connecting member 7.

[0043] Embodiment III

[0044] Please refer to Figure 4 、 Figure 5 and Figure 10 On the basis of Embodiment II, in order to facilitate the connection between the connecting plate and the adapter backing plate 9, a fixing bolt 11 is provided. The adapter backing plate 9 is fixedly connected to the bottom of the vertical connecting member 7. One end of the connecting plate 15 is sleeved on the mounting bolt 14, and the other end of the connecting plate 15 is sleeved on the fixing bolt 11. The connecting plate 15 is in a square plate structure. An installation nut 28 is screwed on the surface of the fixing bolt 11. The fixing bolt 11 cooperates with the installation nut 28 to fix the connecting plate 15. The fixing plate 10 is in a square plate structure. Multiple groups of fixing plates 10 are provided. All the multiple groups of fixing plates 10 are arranged at the bottom of the adapter backing plate 9. A threaded groove 29 is formed on the side surface of the fixing plate 10. The threaded groove 29 is in an annular plate structure. A positioning tube 30 is screwed in the threaded groove 29. An auxiliary plate 31 is arranged at the end face of the positioning tube 30. The auxiliary plate 31 is in an annular plate structure. The diameter of the positioning tube 30 is larger than the diameter of the fixing bolt 11;

[0045] In use, first, directly pass the fixing bolt 11 through the connecting plate 15 and the fixing plate 10. Then, directly screw the mounting nut 28 onto the fixing bolt 11 and tighten the mounting nut 28, thereby fixing the connecting plate 15. Then, screw the positioning tube 30 into the threaded groove 29, and use the auxiliary plate 31 provided on the end face of the positioning tube 30 to press against the surface of the mounting nut 28 to prevent the mounting nut 28 from loosening. In addition, compared with the traditional keel span designed as a simply supported beam or a double-span beam, the span should be calculated as L1 + L2 according to the traditional design. However, in the system of the present invention, the span can be calculated as L1, and the L2 part is considered as a connecting piece, thereby achieving the purpose of reducing the span. The reduction of the span is helpful for reducing the keel specification and optimizing the material cost. Moreover, the combined design of the two sections of L1 and L2 is more flexible when adapting to the situation of variable height.
