[0027] The working principle of the large-span glass curtain wall steel column connection system provided by the present utility model is as follows:
[0028] During use, first fix the steel column 1 to the side wall of the main wall 21 through the angle steel 22, so that the steel column 1 is fixedly connected to the main wall 21. Then, snap the positioning frame 41 into the notches preset on the side walls at both ends of the steel column 1, and fix the positioning block inside the side wall of the steel column 1 through the fixing bolt 43. Then, thread-connect the open end of the insertion tube 51 to the screw hole preset inside one end of the positioning frame 41, so that the insertion tubes 51 are equidistantly installed from top to bottom, and the sliding openings on the side walls of the insertion tubes 51 are in the positive direction. Then, sleuth the cross beam frame 31 onto the side wall of the insertion tube 51 through the through hole 33 provided inside the positioning block, so that one end of the cross beam frame 31 is snapped into the positioning groove 42 provided at one end of the positioning frame 41 along the insertion tube 51, so that the cross beam frame 31 is clamped to the steel column 1 through the positioning frame 41.

As the limit plate 62 slides, it will drive the push rod 63 to abut against the side wall of the baffle 56, and then push the baffle 56 to drive the fixed rod 55 to move towards the other end inside the insertion tube 51. Immediately, the fixed rod 55 drives the push block 54 to squeeze the clamping block 52 out of the insertion tube 51. When the clamping block 52 slides out, it will be clamped inside the clamping groove 34 to limit the position of the cross beam frame 31, so that the cross beam frame 31 is firmly fixed to the side wall of the steel column 1.

Then, the connection structure 5 is threadedly connected to the inside of one end of the positioning structure 4 to make the through port where the block 52 inside the connection structure 5 slides in the positive direction. Then, one end of the crossbeam structure 3 is sleeved on the side wall of the connection structure 5, and it is inserted into the inside of one end of the positioning structure 4 along the connection structure 5, so that the crossbeam structure 3 is clamped together with the steel column 1 through the positioning structure 4. Then, a tool is used to drive the limiting structure 6 inside the positioning structure 4, so that the limiting structure 6 slides inside the positioning structure 4, and the push rod 63 in the positioning structure 4 is inserted into the inside of one end of the connection structure 5. Then, the fixed rod 55 inside the connection structure 5 is pushed to move through the push rod 63, so that the block 52 can be driven to slide out of the inside of the connection structure 5 and then clamped together with the crossbeam structure 3, so that the crossbeam structure 3 is clamped and fixed together with the positioning structure 4 through the connection structure 5, strengthening the stability of the connection between the crossbeam structure 3 and the steel column 1. Then, sealant is applied around the intersection point between the positioning structure 4 and the crossbeam structure 3 to seal the inside of the positioning structure 4, so that the internal components do not contact the outside air, and thus the internal components can be protected from oxidation erosion and the service life can be extended. This device has the advantages of facilitating the strengthening of the connection stability of the curtain wall steel column 1 and extending the service life of the curtain wall steel column 1.
