Abstract:
A manual butt-joint steel skeleton, comprising a three-piece set-type manual butt-joint steel skeleton and a two-hook-type manual butt-joint steel skeleton. A male joint (6) and a female joint (5) of a "three-piece butt joint set" are horizontally and vertically connected, and two-hook joints of "two-hook butt joints" are closed to form a round rod and are then tightly sleeved with a sleeve (19), such that a steel pipe (14) is fixedly connected to a #-shaped connection block (15), a single-pipe connection block (16) and a spherical connection block (17). The manual butt-joint steel skeleton can be used as the steel skeleton for stadiums, halls, and buildings, and as the steel skeleton for steel columns of bridge frameworks such as tower cranes, gantry cranes and bridge cranes. The steel skeleton can shorten the construction period, and can save on materials, construction apparatuses and labor, and is excellent in quality, accuracy, firmness and service life.
