Abstract:
A three-piece set-type manual butt-joint steel skeleton, comprising male joints (6) for a #-shaped connection block, a single-pipe connection block and a spherical connection block (2, 3, 4), and a female joint (5) for a steel-pipe end. A sleeve, an inner wall and a steel pipe are referred to as a "three-piece set". All members are connected by manual butt-joint to complete the steel skeletons of stadiums, halls and buildings, and the steel skeletons of steel columns and beam frames of bridge frameworks such as tower cranes, gantry cranes and bridge cranes. The steel skeleton can shorten the construction period and save on materials, construction apparatuses and labor, and is excellent in quality, accuracy, firmness and service life.
