Specifically, in the present embodiment, the socket-type disc-type scaffolding support device adopts modular rod connection, and the disc-type uprights 100, the supporting beams 200 and the first pin shaft 210 are all prefabricated parts. When in use, according to the design drawings, the disc-type uprights 100 of the lower layer are installed first, and then the supporting beams 200 are installed on the disc-type uprights 100 through the first pin shaft 210. After completing one layer, construction is carried out upward in sequence until all the rods are assembled. In this embodiment, the supporting beam 200 is provided with a supporting cross bar 220 and a latch shaft sleeve 230; the latch shaft sleeve 230 is placed between the first disc buckle 110 and the second disc buckle 120, and is fixed by the first pin shaft 210.

The structure is simple, practical and convenient.

[0040] In some embodiments of the present invention, referring to Figures 1 to 4 As shown, it also includes a tie rod group 300; a plurality of third plug holes 112 are provided on the first buckle 110, and a plurality of first plug holes 111 and third plug holes 112 are alternately distributed on the circumference of the first buckle 110; a plurality of fourth plug holes 122 are provided on the second buckle 120, and a plurality of second plug holes 121 and fourth plug holes 122 are alternately distributed on the circumference of the second buckle 120; the tie rod group 300 is provided with a second pin shaft 310, and the second pin shaft 310 can fix the tie rod group 300 between the third plug hole 112 and the fourth plug hole 122. Specifically, in this embodiment, the socket-type buckle scaffold support device includes a buckle upright pole 100, a supporting beam 200 and a tie rod group 300. During construction, the diagonal buckle upright poles 100 are connected by the tie rod group 300 on the same vertical plane, which can further improve the overall bearing capacity and support strength. In this embodiment, the first buckle 110 is provided with 4 first sockets 111 and 4 third sockets 112, and the second buckle 120 is provided with 4 second sockets 121 and 4 fourth sockets 122. The first sockets 111 and the second sockets 121 are arranged corresponding to the front, back, left, and right of the buckle upright 100 in the horizontal direction, and the third sockets 112 and the fourth sockets 122 are alternately distributed between the first sockets 111 and the second sockets 121. Through the design of this structure, the reaction force received by the supporting beam 200 and the pull rod group 300 can pass through the node center of the buckle upright 100, and some of the reaction forces can offset each other. Therefore, through the design of this structure, the bearing capacity and structural strength of the entire frame can be further improved.

[0041] In some embodiments of the present invention, referring to Figure 3 As shown, the diameter of the third plug hole 112 is larger than the diameter of the fourth plug hole 122. In this embodiment, when the pull rod assembly 300 is installed, the two ends of the pull rod can be detachably fixed between the first buckle 110 and the second buckle 120 of the buckle vertical rod 100 through the second pin shaft 310. And by designing that the diameter of the third plug hole 112 is larger than the diameter of the fourth plug hole 122, it is easy to disassemble and assemble the second pin shaft 310.

In this embodiment, the tapered second pin shaft 310 is used for easy assembly and disassembly.

[0044] In some embodiments of the present invention, referring to Figure 5 As shown, the tie rod group 300 includes a first tie rod 320, a second tie rod 330, two tie rod sleeves 340 and an adjusting screw sleeve 350. The first tie rod 320 and the second tie rod 330 are respectively threadedly connected to the two ends of the adjusting screw sleeve 350. The threads of the first tie rod 320 and the second tie rod 330 are in opposite directions. The ends of the first tie rod 320 and the second tie rod 330 that are away from each other are respectively rotatably connected to the two tie rod sleeves 340. The tie rod sleeves 340 are arranged between the first buckle 110 and the second buckle 120 and fixed by the second pin 310. Specifically, in this embodiment, the socket-type buckle scaffold support device includes a buckle upright pole 100, a supporting beam 200 and a tie rod group 300. During construction, the diagonal buckle upright poles 100 are connected by the tie rod group 300 in the same vertical plane, which can further improve the overall bearing capacity and support strength. In this embodiment, the tie rod group 300 is a prefabricated part, which is first assembled as a whole and then sent to the construction area. When installing the tie rod group 300, first measure the installation size, rotate the adjusting screw sleeve 350, so that the first tie rod 320 and the first tie rod 320 are close to or away from each other, as close to the installation size as possible. Further, the two tie rod sleeves 340 are respectively fixed on the buckle upright 100 through the second pin shaft 310. After the tie rod sleeves 340 are fixed and stable, further rotate the adjusting screw sleeve 350 so that the first tie rod 320 and the second tie rod 330 generate pre-tightening force to improve the stability of the overall structure. In this embodiment, the pre-tightening force is 0.2kgf to 0.8kgf, and the specific force applied needs to consider the installation position and actual length of the tie rod group 300.

[0045] In some embodiments of the present invention, referring to Figure 3As shown, the first pin shaft 210 is a conical structure.
