The invention discloses a special-shaped cold-bending thin-wall steel tube concrete column and cold-bending thin-wall box-type steel beam frame joint which comprises cold-bending thin-wall section steel which is shaped like a groove, an L and a line and internal cast-in-place concrete. The ends of all the section steel which forms a steel tube are all provided with right-angle roll rims, plug welding is conducted in external grooves formed by adjacent section steel contact positions, the roll rims of the ends form stiffening ribs to limit local buckling of the steel tube, and in order to enhance the interaction of the stiffening ribs and concrete, holes can be formed in the upper edges of the roll rims at equal intervals in the longitudinal direction. According to a special-shaped cold-bending thin-wall steel tube concrete pipe and cold-bending thin-wall box-type steel beam frame joint, the special-shaped steel tube is formed by directly utilizing the cold-bending thin-wall section steel, the needed steel quantity is lower than that of a traditional steel tube concrete column, construction procedure of welding the stiffening ribs is omitted simultaneously, and the special-shaped cold-bending thin-wall steel tube concrete pipe and cold-bending thin-wall box-type steel beam frame joint is a steel and concrete combined structural element which is good in mechanical property, convenient to construct, economical and reasonable.
