METHOD OF REINFORCING ROOF PANEL OR FLOOR PANEL, REINFORCING STRUCTURE, AND BEARING FITTING FOR REINFORCEMENT

摘要

PROBLEM TO BE SOLVED: To provide a reinforcing method which is implemented when an existing roof panel or a floor panel undergoes strength deterioration or increased deflection due to aged deterioration or damage, dispenses with removal of upper finish, use of heavy equipment, and working on an existing beam, is carried out from below without welding, insusceptible to building applications, requires only relatively simple work, and exerts reliable strength.;SOLUTION: According to the reinforcing method, an inside of a notch formed in a first vertical piece and an inside of a notch formed in a second vertical piece of a bearing fitting for reinforcement, abutted on an upper surface of an upper flange (2a) of an H-shaped steel beam (2), and a first bolt (5) abutted on a lower surface of the upper flange (2a) cooperatively pinch the upper flange (2a), and the first bolt (5) is turned and fastened. Then a second bolt (6) is turned and fastened such that a reinforcing steel (7) horizontally inserted into the bearing fitting from the side where the second bolt (6) is located, retains a lower surface of the roof panel or the floor panel (1).;COPYRIGHT: (C)2007,JPO&INPIT
