Abstract: A steel structural connector, comprising a vertically-oriented connecting body for connecting to columns and a horizontally-oriented connecting body for connecting to beams, where one end of the horizontally-oriented connecting body is connected to the vertically-oriented connecting body. The vertically-oriented connecting body further includes sequentially arranged front sidewall, left sidewall, rear sidewall, and right sidewall. On at least one end of the vertically-oriented connecting body, there are several installation through-holes for connecting to columns. The vertically-oriented connecting body has installation through-holes on one end of each sidewall with an inwardly extending concave portion along the length direction of the vertically-oriented connecting body. The installation through-holes are placed within the concave portion.

Abstract: An assembly column-beam connection component includes a vertically-oriented connecting body for connecting to columns and a horizontally-oriented connecting body for connecting to beams. One end of the horizontally-oriented connecting body is connected to the vertically-oriented connecting body. The vertically-oriented connecting body includes sequentially arranged front sidewall, left sidewall, rear sidewall, and right sidewall. Each of these sidewalls features concave portions extending along the vertically-oriented connecting body's length in the vertical direction. The concave portions on the left sidewall and rear sidewall are positioned near the junction of the left sidewall and rear sidewall, while those on the front sidewall and right sidewall are situated at their respective centers. Multiple installation through-holes for connecting to columns are provided on the various sidewalls of at least one end of the vertically-oriented connecting body.
