DEFLECTION PREVENTING METAL FITTING, AND METALLIC FLOOR PANEL REINFORCEMENT METHOD AND REINFORCEMENT STRUCTURE USING THE SAME

Japanese Patent JP2017218779

A

PROBLEM TO BE SOLVED: To provide a highly workable and economically feasible deflection preventing metal fitting that may be fitted from above a metallic floor panel, along with a metallic floor panel reinforcement method and a reinforcement structure using the deflection preventing metal fitting.SOLUTION: A deflection preventing metal fitting 1 comprises an upper-side member 2, a lower-side member 3, and a bolt 4 connecting the upper- and lower-side members. The upper-side member 2 includes a recess 2a in an intermediate part, to be fitted in a slit S, and is of a form mountable on a top surface plate 10a. A bolt hole 2b is formed on the recess 2a, penetrating in a vertical direction. The lower-side member 3 includes a flat plate part 3a into which the bolt 4 may be screwed, and a standing part 3b provided on both edge parts of the flat plate part 3a and coming in contact with a rear surface of the top surface plate, the lower-side member being of a form that may pass through the slit S. A bottom end of the bolt 4 penetrating through the recess 2a and the flat plate part 3a in the vertical direction may almost come into contact with a beam junction part 12 and other lower members.SELECTED DRAWING: Figure 1
