PURPOSE: Structure of a bus frame using a decking method is provided to improve assembling efficiency and sealing efficiency in the bonding portion of frames by concentrating the welding portion without bolts with forming skid rails in upper and lower body frames, and to cut down manufacturing cost by modularizing the lower body frame and the floor frame. CONSTITUTION: A bus frame is composed of an upper body frame(10) forming the frame of a vehicle body; a lower body frame(20) combined with the upper body frame to form the lower frame of the vehicle body and integrally formed with a floor frame(40); and a skid frame(30) assembling the upper body frame and the lower body frame. The skid frame has a skirt rail(32) supported by a pillar(33) and directly combined with both sides of the lower body frame to form the lower portion of the vehicle body side, and skid rails(31) mounted to the upper part of the skirt rail and the lower part of the upper body frame.
