<P>PROBLEM TO BE SOLVED: To provide a connection structure of building panels, for further improving connection strength of a fitting part while keeping design and corrosion resistance in a structure of fitting and connecting a fitting projection part and a fitting recessed part, and a fastener used for it. <P>SOLUTION: In the connection structure of the building panels of this invention, a core material 3 is disposed between a first metal skin 1 and a second metal skin 2. A fitting recessed part 4 includes a first outer piece 41 forming an outer side face of the fitting recessed part 4, a first inner piece 42 forming an inner side face of the fitting recessed part 4, a second outer piece 46 forming an outer side face of the fitting recessed part 4, and a second inner piece 47 for forming an inner side face of the fitting recessed part 4. In the state that the fitting recessed part 4 and a fitting projection part 5 are fitted, a fastener 6 is placed from the first outer piece 41 to the fitting projection part 5, and the fastener 6 passes through the first outer piece 41, the first inner piece 42, the fitting projection part 5 and the second inner piece 47 but does not pass through the second outer piece 46. <P>COPYRIGHT: (C)2013,JPO&INPIT |
