Meanwhile being connected between second cross beam 2 and gravity pillar 3 by pin shaft 4, when the lower part of gravity pillar 3 collapses
When failure, pin shaft 4 and the lower end surface of the first connecting hole 211 are in contact, and gravity pillar 3 is changed into tension by compression, and rises
It is acted on to suspension, second cross beam 2 is hung up gravity pillar 3 by pin shaft 4, guarantees that construction steel structure will not occur continuously to fall
It collapses.The pulling force that the cross-sectional area of pin shaft 4 is subjected to after being failed according to gravity pillar 3 is calculated.
The construction steel structure of the embodiment of the present invention, as shown in Fig. 2, pin shaft is in first connecting hole 211 along vertical side
To movement, the first connecting hole 211 is long hole, and the length direction of the first connecting hole 211 extends along the vertical direction, and pin shaft 4 is located at
The lower end of long hole, when second cross beam 2 generates downward deformational displacement under the action of gravitational load, pin shaft 4 connects along first
Hole 211 is connect to move upwards；The distance between upper surface of pin shaft 4 and the first connecting hole 211 is greater than or equal to column cap 32 and second
Gap between crossbeam 2 vertical direction height so that second cross beam 2 is after largest deformation displacement, the first connecting hole 211 according to
Certain gap is so remained in the vertical direction with pin shaft 4, so that it is guaranteed that the constuction loads of 2 top of second cross beam will not pass through
Pin shaft 4 is transferred to the gravity pillar 3 of lower section.
