N0 Rk,c＝9.8×fcu,k 0.5×hef 1.5＝9.8×2000.5×2001.5＝392kN
Ac,n＝(c2+0.5scr,sp)(s1+scr,sp)＝(84+0.5×800)×(120+800)＝4.45×105mm2
_______________________________________
A0 c,n＝Scr,sp 2＝(4hef)2＝800×800＝6.4×105mm2
ps,n＝0.7+0.3×c/ccr.n＝0.7+0.3×0/(2×200)＝0.7
p re,n＝0.5+hef/200=0.5+200/200=1.5, the specification requires pre, n.ltoreq.1, 1.0
pec,n＝1/(1+2en/Scr,n)＝1/(1+0)＝1.0
Then N Rk,c＝N0 Rkc×Acn/A0 cn×ps,n×pre,n×pec,n

The sliding rod 112 is driven to slide along the mounting cavity 111 through the driving part, at this time, the sliding rod 112 extrudes the elastic spring 118, and the anti-falling rod 115 stretches out from the outer surface of the horizontal hanging rod 7 under the action of the linkage part, so that the anti-falling rod 115 can be abutted against the top of the beam or the enclosure structure of the top of the beam, the horizontal hanging rod 7 is not easy to be pulled out from the top of the beam or the enclosure structure of the top of the beam, and the connection strength and the connection stability of the horizontal hanging rod 7 in the top of the beam or the enclosure structure of the top of the beam are improved.
In order to further improve the contact strength of the anti-drop rod 115 and the roof or the enclosure, the end of the anti-drop rod 115 is provided with a guiding inclined plane 125, the inclined direction of the guiding inclined plane 125 is the same as the inclined direction of the inclined hole 114, and the end of the anti-drop rod 115 forms a spike through the arrangement of the guiding inclined plane 125.
The vertical steel pipe 2 is hollow, and the driving part is arranged in the vertical steel pipe 2 and is opposite to the sliding rod 112. The drive part comprises a drive opening 121 formed in the side wall of the vertical steel pipe 2 and a drive block 122 slidably mounted in the drive opening 121, the drive block 122 is horizontally arranged, a drive spring 123 is arranged in the vertical steel pipe 2, one end of the drive spring 123 is fixed on the inner wall of the vertical steel pipe 2, the other end of the drive spring 123 is fixed on the drive block 122, the end part of the drive block 122 is provided with a conical surface 124, and the drive block 122 is used for abutting against the sliding rod 112 to drive the sliding rod 112 to act.
Thus, when the sliding collar 6 is rotated such that the mounting port 120 is opposite to the position of the driving port 121, the driving block 122 will protrude from the driving port 121 and abut against the sliding rod 112 to drive the sliding rod 112 to act, so that the anti-drop rod 115 protrudes from the outer surface of the horizontal hanger bar 7. When the mounting opening 120 of the sliding collar 6 is not opposite to the position of the driving opening 121, the driving block 122 will be hidden into the driving opening 121, so that no interference is caused to the rotation and the socket mounting of the sliding collar 6 on the vertical steel pipe 2.
By the arrangement of the driving part, the sliding collar 6 rotates, and after the horizontal hanging rod 7 is transversely arranged on the top of the beam, the driving block 122 can push the sliding rod 112. When the horizontal hanging rod 7 is required to be moved out of the top of the beam, the driving block 122 can be compressed and contracted into the driving opening 121 by rotating the sliding sleeve ring 6 or drawing out the vertical steel pipe 2 from the sliding sleeve ring 6, and the horizontal hanging rod is not abutted on the sliding rod 112 any more, so that the operation is simple and the convenience is high.
