[0051] After the steel structure cross beam components are installed as a whole, the side wall of one of the first cross beam components 1 is fitted with the inner wall of the stabilizing groove, and then the three mounting plates 23 are respectively connected to the two first cross beam components 1 and the one second cross beam component 2 by multiple bolts, so that the steel structure cross beam components are stably installed as a whole on the column 20;

[0052] When the damaged first cross beam member 1 located at the outermost side needs to be replaced later, the screw rod 12 located at the outermost side of the first cross beam member 1 is disassembled, so that the two first L-shaped plates 11 move away from each other to the initial position, and the two first plates 6 move away from each other to the original position under the action of the multiple first springs 7, so that the multiple first clamping blocks 8 are separated from the multiple first clamping grooves 9, and the two second plates 14 move away from each other to the original position under the action of the four cross plates 18, the four rotating plates 19 and the multiple second springs 15, so that the multiple second clamping blocks 16 are separated from the multiple second clamping grooves 17;

Then, the staff can only replace the outermost first cross beam member 1, and only need to reverse the above steps in the future to complete the installation between the replaced first cross beam member 1 and the second cross beam member 2;

[0054] When the second cross beam member 2 needs to be replaced, the two screws 12 need to be disassembled, and then the second electric push rod 32 at the top needs to be adjusted to retract, so that the third tooth plate 33 there is separated from the second gear 28 at the top, and then the first electric push rod 29 needs to be adjusted to retract, so that the second tooth plate 31 and the third tooth plate 33 can drive the two second L-shaped plates 22 below to move out of the strip cavity 21 through the two second gears 28, the two cross bars 26 and the two first tooth plates 25, so that the outermost first cross beam member 1 and the second cross beam member 2 move outward, and the moving distance of the outermost first cross beam member 1 is greater than the moving distance of the second cross beam member 2, so that the two connecting plates 3 on the second cross beam member 2 are separated from the connecting groove 4, and then the staff can only replace the second cross beam member 2, and only need to reverse the above steps later to complete the connection between the replaced second cross beam member 2 and the installed first cross beam member 1 between the two;

[0055] When the innermost first cross beam member 1 needs to be replaced, the screw rod 12 on the innermost first cross beam member 1 is disassembled;

[0056] Then, the middle second electric push rod 32 is adjusted to retract so that the middle third tooth plate 33 is separated from the second gear 28, and then the first electric push rod 29 is adjusted to retract so that the Z-shaped plate 30 moves downward. At this time, the second tooth plate 31 and the third tooth plate 33 located at the top will drive the first tooth plate 25 located at the bottom and the first tooth plate 25 located at the top to move out of the strip cavity 21 through the second gear 28 and the cross bar 26 there, so that the second L-shaped plate 22 located at the bottom and the second L-shaped plate 22 located at the top move outward, so that the second cross beam member 2 is separated from the first cross beam member 1 located on the inside, and the first cross beam member 1 will also be separated from the stabilizing groove. Then, the staff can only replace the innermost first cross beam member 1, and only need to reverse the above steps in the future to complete the installation between the replaced first cross beam member 1 and the second cross beam member 2.

[0057] In this way, the crossbeam components at the sections can be replaced in a targeted manner without causing waste, and the energy-saving effect is good. This avoids the situation in the prior art where, if a steel structure crossbeam component of a section needs to be replaced in the future, the entire steel structure crossbeam component needs to be disassembled and replaced as a whole, and cannot be disassembled and replaced in a targeted manner.
