为提高拆装式钢结构整体刚度，减小拼组结构的非弹性销（栓）孔变位挠度，研制了一种新的连接件──充盈式锥形钢销。阐明了此新型紧固件的工作机理，并给出了构造及装配图，以便在工程实际中推广运用。
In order to improve the overall rigidity of the disassembly-type steel structure and reduce the deflection of the inelastic pin (bolt) hole in the assembled structure, a new type of connector, namely the filling tapered steel pin, was developed. The working principle of the new fastener is expounded, and the structure and assembly drawing are given to popularize and apply it in engineering practice.
