<p>PURPOSE: A frame structure for a flat bed trailer is provided to improve the productivity and to save the production cost of the frame structure by attaching sheets which could be easily processed. CONSTITUTION: A frame structure for a flat bed trailer comprises a master beam(10), vertical beams(20), a top reinforcing member(30), a side reinforcing member, and a bottom reinforcing member. The master beam forms the skeleton of the frame structure. The vertical beams are arranged in parallel to each other along the inner length direction of the master beam. The top reinforcing member is attached along the upper length direction of the vertical beam to reinforce the upper rigidity of the frame structure. The side reinforcing member is attached to vertically face between the master beam and the vertical beam to reinforce the side rigidity of the frame structure. The bottom reinforcing member is attached along the length direction of the master beam and the vertical beam to reinforce the bottom rigidity of the frame structure.</p> |
