The invention relates to a building steel structure combination device and discloses a combination body for completely blocking a building structural steel cold bridge. The device comprises a bottom layer profiled steel sheet (1), a steel structure purline (2), a thermal insulation cushion block (3), a cold bridge prevention self-tapping screw (4), a vapor-proof layer (5), heat preservation rock wool (6), a waterproof breathable film (7), a fixing support (8), an outer heat preservation board (9) and double-sided adhesive tape (10). The bottom layer profiled steel sheet (1) and the high-intensity thermal insulation cushion block (3) are fixed to the steel structure purline (2) through the high-performance double-sided adhesive tape (10), the vapor-proof layer (5) is arranged on the inner side of the heat preservation layer, the heat preservation rock wool (6) is arranged and covered with the waterproof breathable film (7), the fixing support (8) and the outer heat preservation board (9) are fixed on the high-intensity thermal insulation cushion block (3) through the cold bridge prevention self-tapping screw (4), and therefore a whole heat preservation and thermal insulation device is formed. The combination body can be applied to various steel structure buildings having requirements for heat preservation and cold preservation.
