[0068] Embodiment 2:

[0069] The embodiment of the application discloses a modular assembly type steel structure system.

[0070] Referring to Figure 9 and Figure 10 , the difference between the embodiment 2 and the embodiment 1 is that the disassembling assembly 4 comprises two disassembling pieces 44, the disassembling pieces 44 are respectively located at opposite two side walls of the connecting groove 134; the disassembling piece 44 comprises a supporting block 441, a moving block 442 and a plug rod 443, a supporting groove 45 is formed in the inner wall of the connecting groove 134, and the supporting block 441 is movably installed in the supporting groove 45; when the supporting blocks 441 of the two disassembling pieces 44 abut against each other, the connecting ring 36 is sleeved on the outer wall of the supporting block 441, so that the situation that the connecting ring 36 is separated from the connecting groove 134 can be reduced; the supporting block 441 is fixed with an elastic block 444, and a clamping groove 445 is formed in the side of the supporting block 441 close to the elastic block 444; when the supporting blocks 441 of the two disassembling pieces 44 abut against each other, the elastic block 444 of the supporting block 441 is clamped in the clamping groove 445 of the adjacent supporting block 441. Through the interference fit of the supporting block 441 and the clamping groove 445, the situation that the stand column 13 is separated from the connecting groove 134 in the carrying process can be reduced.

[0071] Referring to Figure 11 , the plug rod 443 is fixed to the supporting block 441; a moving groove 46 is formed in the inner wall of the plug interface 131, the moving groove 46 is communicated with the supporting groove 45, and the moving block 442 is movably installed in the moving groove 46; a plug groove 446 is formed in the side of the moving block 442 close to the supporting block 441, and the end of the plug groove 446 away from the moving groove 46 faces away; a moving groove is formed in the side wall of the moving block 442, and the moving groove is communicated with the plug groove 446; the plug rod 443 is arranged in the moving groove and is slidably connected with the plug groove 446 through a sliding block 447.
