REINFORCEMENT STRUCTURE OF STRUCTURE MADE USING STEEL PLATE

摘要

PURPOSE: A reinforcement structure of a structure using a reinforcement plate is provided to reinforce the load of a horizontal structure member and a vertical structure member of a construction structure by a vertical enforcement part and a horizontal enforcement part. CONSTITUTION: A reinforcement structure (100) of a structure using a reinforcement plate comprises a column structure (110), a vertical enforcement part (130), and a horizontal enforcement part (150). The column structure is welded to a horizontal structure member and has an angular cross section. The vertical enforcement part is attached to the outer periphery of the column structure and includes a first reinforcement plate (131) which is combined to form a closed section. The horizontal enforcement part is attached to the horizontal structure member and a junction part of the column structure and includes a second reinforcement plate (151). The second reinforcement plate is combined into between the horizontal structure member and the vertical enforcement part and supports the load of the horizontal structure member. The second reinforcement plate includes an expansion part (153) protruding from the outside of a corner and reinforces the stress concentration of the corner part of the column structure.
