<P>PROBLEM TO BE SOLVED: To provide a floor panel for a steel structure, a floor panel junction structure and a floor framing of steel structure for facilitating easy laying floor panels and for securing horizontal rigidity of a floor with the floor panel with ease. <P>SOLUTION: A floor panel 2 having a floor joist 3 and a floor panel 1 having a header joist 4 are laid adjacent to each other. The floor joist 3 and the header joist 4 are composed of lightweight H-shape steel. An end part of the floor joist 3 is connected to a side part of the header joist 4 via a joint metal 6. The joint metal 6 is formed in an approximately T-shape in a plan view from a fixing portion 6a which is installed on a web 4a of the header joist 4 and a connecting portion 6b which protrudes from the fixing portion 6a to a side of a web 3a of the floor joist 3 and installed on the side portion of the web 3a. A lower flange 3c of the floor joist 3 is formed shorter than an upper flange 3b to a degree that the lower flange 3c does not interfere with the connecting portion 6b of the joint metal 6 at an end portion of the lower flange 3c to which the joint metal 6 is installed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
