PROBLEM TO BE SOLVED: To make the subject connection structure lightweight, and contrive the maintenance of the fire protection of a connection part by deformation under high temperature. SOLUTION: Fire protection roof panels P integrally forming a pair of surface plates 1 formed by aluminum members respectively, a frame material 10 interposed between the side parts of both the surface plates 1, and a core material 2 providing in the inside of a space formed of both the surface plates 1 and the frame material 10 are connected. A projection 14 projecting outward is a formed on the frame material 10, an upper connection member 20 and a lower connection member 21 are engaged on the upper face and lower face of the projections 14 of both the connected panels P respectively, the upper connection member 20 and the lower connection member 21 are tightened by bolts 31 and nuts 32 being tightening members, and the projections 14 of both the panels P are sandwiched. Thereby, the connection part (joint part) of both the panels P is opened under high temperature to prevent the spread of a fire.
