    摘要: A dovetail track groove bolt includes a T-shaped body having a bolt head 1 and bolt shaft 2. The bolt head has inclined limiting surfaces 11 on both sides, and its longitudinal cross-section forms a "dovetail shape." The width of the bolt head is equipped with installation surfaces 12 on both sides, and at the diagonal junction of the limiting surfaces and installation surfaces, avoidance surfaces 13 are placed. This irregular bolt, through the implementation of a dovetail-shaped bolt head matching the dovetail track groove, redistributes the vertical gravitational force into horizontal and longitudinal forces, effectively dispersing the track groove's bearing load and enhancing the overall bearing capacity. Simultaneously, by introducing installation surfaces and avoidance surfaces, the bolt head can be inserted directly into the dovetail track groove's slot and aligned through rotation, thereby expediting the installation process.

    摘要: 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. The present invention enhances the stability and structural strength of connections when used at locations with installation through-holes for external vertical components, while simultaneously connecting both horizontal and vertical components.
