According to the scheme, the through holes 221 are formed in the bottom plate 22 and the accommodating grooves 211 are formed in the bottom of the upright post 21, so that the shear keys 30 can penetrate through the bottom plate 22 and are connected with the upright post 21 through the connecting pieces 40, when the steel structure column base node bears horizontal shear force, the bottom plate 22 can resist the shear force, and the maximum horizontal shear force borne by the whole steel structure column base node is greatly improved; further, by arranging the connecting piece 40, the connection stability of the shear key 30 and the steel column 20 can be improved; in addition, since the shear keys 30 are pre-embedded in the concrete column 10, there is no problem that the size of the shear groove is not matched with that of the shear key 30 in the prior art.
In one embodiment, the shear key 30 has an H-shape, and the through hole 221 has a shape matching the shape of the shear key 30 with a gap between the shear key 30 and the through hole. That is, the through-hole 221 is also H-shaped, but is slightly larger than the shear key 30 in size, thereby facilitating the penetration of the shear key 30. The shape of the shear key 30 is not limited to the H-shape, and those skilled in the art can select the size and shape of the shear key according to actual requirements.
Specifically, the upright 21 includes two first side plates 212 and a first middle plate 213 located between the two first side plates 212, the two first side plates 212 and the first middle plate 213 are connected to form an H-shape, and the receiving groove 211 is formed at the bottom of the first middle plate 213.

And grouting material is filled between the bottom plate 22 and the top surface of the concrete column 10. The grouting material can adopt high-strength grouting material.
Further, the top of the shear key 30 is flush with the top of the receiving groove 211; the width of the receiving groove 211 is equal to the width of the shear key 30. So that the shear key 30 can be fitted in the receiving groove 211 to facilitate the connection of the connection member 40.
In the present embodiment, the longitudinal direction of the column 21 is perpendicular to the bottom plate 22.
Next, the construction method of the steel structure column base joint according to the present embodiment will be described with reference to fig. 1 and 2.
(1) Before the concrete column 10 is cast, the shear keys 30 are previously placed in the form of the concrete column 10 and welded to the reinforcing bars in the concrete column 10. Concrete is then poured so that the shear keys 30 become part of the concrete column 10, which is formed as a unit. The shear keys 30 are elevated a distance above the top of the bottom plate 22.
(2) The through holes 221 of the bottom plates 22 of the steel columns 20 are aligned with the tops of the shear keys 30, and the bottom plates 22 are sleeved on the shear keys 30, and the tops of the shear keys 30 are inserted into the receiving grooves 211.
(3) The shear key 30 and the upright post 21 are welded and connected by adopting a connecting angle steel 42 and a connecting steel plate 41.
(4) A certain gap needs to be reserved between the bottom surface of the bottom plate 22 and the top surface of the concrete column 10, and after welding is completed, the gap is filled with high-strength grouting material.
The steel structure column base node which is actually worked by adopting the mode has strong shearing resistance, solves the problem of construction error caused by the fact that the shearing resistance key is placed later by embedding the shearing resistance key in advance, improves the construction efficiency to a greater extent, and realizes greater economic and social benefits.
