[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] like Figure 1 , Figure 2 , Figure 3 As shown, a weld-free ceiling transition layer structure includes a top plate 1, columns 2, a bottom plate 3, a transition head 4, and supporting angle steel 5.

[0017] like Figure 1 , Figure 2 , Figure 3 As shown, the top plate 1 is elongated and is horizontally fixed to the roof by expansion bolts. The column 2 is vertically installed below the top plate 1, and the bottom plate 3 is horizontally installed at the lower end of the column 2.

[0018] like Figure 1 , Figure 2 , Figure 3 As shown, the top plate 1 and the bottom plate 3 are respectively provided with a top insertion tube 6 and a bottom insertion tube 7 for the two ends of the column 2 to be inserted into, and both the top insertion tube 6 and the bottom insertion tube 7 are horizontally provided with tie rods 8 that pass through the column 2.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, the converter head 4 has a square cross-section and is fixed to the bottom plate 3 with bolts. Connecting angle steels 41 are horizontally arranged around the converter head 4. Supporting angle steels 5 are horizontally fastened to the outside of the connecting angle steels 41 and fixed to the connecting angle steels 41 with bolts.

[0020] When construction of the ceiling transition layer is required, first fix the top plate 1 horizontally to the roof using expansion bolts. Then, insert the upper end of the column 2 into the top insertion tube 6 and fix it using tie rods 8. Next, fit the bottom insertion tube 7 on the base plate 3 under the column 2 and fix it using tie rods 8 to complete the assembly and fixing of the top plate 1, column 2, and base plate 3.

[0021] Then, fix the adapter 4 to the bottom of the base plate 3, and then horizontally fasten the support angle steel 5 to the outside of each connecting angle steel 41, and fix them together with bolts to complete the on-site construction of the entire ceiling conversion layer.

[0022] Therefore, by setting up a modular ceiling transition layer and using bolting to fix the various components, the components can be prefabricated in the factory and then quickly assembled and fixed on site without welding. This can shorten the construction cycle, save construction costs, and improve the stability of the ceiling.

[0023] like Figure 4As shown, the upper end face of the converter head 4 is vertically provided with multiple hooks 42, and the base plate 3 is provided with a locking hole 31 for the hooks 42 to pass through.

[0024] like Figure 4 As shown, a locking ring 71 is vertically slidably connected to the outer wall of the bottom insertion tube 7. The locking ring 71 is used to be embedded in the gap between multiple hooks 42. A pin 72 with a threaded connection to the bottom insertion tube 7 is provided on the locking ring 71.

[0025] When the adapter 4 needs to be installed, the hooks 42 on the adapter 4 are passed through the holes 31 on the base plate 3 to complete the initial snap-fit ​​fixation. Then, the control locking ring 71 slides down to make the locking ring 71 embed into the gap between the multiple hooks 42, and the pins 72 are tightened to lock the hooks 42, increase the stability of the connection position of the adapter 4, and ensure a tight connection.

[0026] like Figure 2 As shown, the column 2 includes a top pipe 21 and a bottom pipe 22. The top pipe 21 is vertically slidably connected to the bottom pipe 22. A locking bolt 23 is provided through the upper end of the bottom pipe 22. A row of locking holes 24 for the locking bolt 23 to pass through is provided on the top pipe 21.

[0027] When it is necessary to adjust the overall length of the column 2, the top pipe 21 and the bottom pipe 22 can be controlled to slide relative to each other, and then the locking bolt 23 can be passed through the corresponding locking hole 24 to realize the length adjustment of the column 2 to meet the installation requirements of different heights.

[0028] like Figure 2 As shown, diagonal braces 9 are installed on both sides of the jacking pipe 21 and the top plate 1, and both ends of the diagonal braces 9 are bolted to the jacking pipe 21 and the top plate 1. Therefore, by installing diagonal braces 9, the structural strength and stability between the entire column 2 and the top plate 1 can be increased.

[0029] like Figure 3 As shown, the supporting angle steel 5 includes a pair of end angle steels 51 and a middle angle steel 52, with the middle angle steel 52 fastened to the inside of the pair of end angle steels 51.

[0032] When the overall length of the supporting angle steel 5 needs to be adjusted, the relative sliding of the end angle steel 51 and the middle angle steel 52 can be controlled. During sliding, the sliding of the end angle steel 51 and the middle angle steel 52 can be limited by the cooperation of the limiting rivet 53 and the limiting hole 54. Finally, the fixing bolt 56 is passed through the corresponding fixing hole 55 to fix the supporting angle steel 5 and adjust its length to meet the installation requirements of different spans.
