The invention discloses an L-shaped special-shaped column and beam fabricated connecting joint, and belongs to the technical field of
structural engineering. The L-shaped special-shaped column and beam fabricated connecting joint is composed of a special-shaped column, I-shaped beams, channel steel connecting pieces and high-strength bolt groups. Manufacturing and
welding parts of steel componentsare completed in a factory, the
welding quality is easy to control, only each prefabricated component needs to be hoisted, and is connected through a high-strength bolt on a construction site, and the construction efficiency is high; and the connecting joint has the advantages of
mechanical property and practical property at the same time, and specifically, in the aspect of the
mechanical property, the connecting joint makes full use of the
bearing capacity and the
lateral stiffness of the special-shaped column, and has the good anti-seismic property; and in the aspect of the practical property, the connecting joint emphatically achieves the rapid
assembly concept, and solves the "protruding column" problem in a house.
