Example 1

As shown in fig. 1 to 4, a steel structure stand column welding-free installation butt joint device is installed at a position of a terminal surface 3 of a steel structure stand column, wherein an upper group and a lower group of butt joint joints are used as symmetrical axes and are oppositely arranged, the butt joint device is composed of a butt joint plate 1, a fastening sleeve 4, a pin shaft 2 and a fastening bolt 5, the butt joint plate 1 is installed on the stand column butt joint terminal surface 3, the fastening sleeve 4 is connected with the butt joint plate 1 and extends out of the stand column butt joint terminal surface 3, the positions of the fastening sleeves 4 of the upper group and the lower group of butt joint devices are opposite, a through hole for inserting the fastening bolt is formed in the fastening sleeve 4, a pin hole 6 for inserting the pin shaft is formed in the butt joint plate, and the positions of the pin.

Wherein, there is bellied step 7 in the middle of the round pin axle, the pinhole has step 8 with round pin axle matched with. The height of the step 8 of the pin hole is larger than half of the thickness of the raised step 7 and smaller than the height of the raised step 7. Set up round pin axle 2 and pinhole 6 like this, just can be with round pin axle 2 equipartition, half card is in pinhole 6, and half stretches out for the location, the protruding step 7 of round pin axle thickness is less than the thickness of step 8 in the butt joint board that is in the same place of two butt joint devices that set up relatively simultaneously, and when the location was accomplished like this, two butt joint boards 1 are close contact with each other, just so can guarantee the reliable butt joint of stand terminal surface.

The pin hole 6 is far away from the direction of the upright column butt joint end face 3, a sleeve 9 extends, and the diameter of the sleeve 9 is matched with that of the pin shaft 2. The effect of sleeve pipe 9 can play the effect of guide pin axle 2, and when round pin axle 2 inserted pinhole 6, can play the effect of protection round pin axle 2 simultaneously, the sleeve pipe 9 of extension also can play the effect that reduces the axial and rock.

The fastening sleeve 4 can be welded on one side of the butt plate, and the lower end face of the fastening sleeve 4 is flush with the butt plate 1. Another form of fastening sleeve 4 is integrally formed with the butt plate 1. The fastening sleeve 4 arranged in a split manner can save materials, can be welded, and can flexibly find the welding position of the butt joint plate, and the flexible welding position can avoid the position of equipment needing to be avoided when each project is used, so that space interference is avoided. Of course, the fastening sleeve and the butt plate which are integrally formed can be uniformly arranged at a position which can avoid space interference, so that the difficulty in assembling is greatly reduced.

The number of the fastening sleeves 4 of the butt joint device is 2, and the fastening sleeves are respectively positioned on the corners of the adjacent edges of the butt joint plate 1. The 2 fastening sleeves can increase the stability after fastening. The butt-joint plate is welded on the butt-joint end face of the upright post, and the projection of the butt-joint plate does not exceed the end face of the upright post.
