A through hole is formed for a nail to join the substrate to the substrate, and a through hole is formed on the downwardly facing side surface of the substrate to penetrate the core material at the end of the roof panel that abuts the substrate from the lower side of the slope of the roof. It is characterized by a protruding screw shaft.

``Function'' The substrate becomes a receiving member for receiving the edge of the roof panel while being fixed on the binding material, making the installation work of the roof panel easier, increasing the installation accuracy, and
By screwing a nut into the screw shaft penetrating the core material of the roof panel from below the roof panel, the roof panel can be joined to the support without going up onto the roof panel.

"Effects of the Invention" As explained above, the present invention consists of a fixing plate that is placed on the upper surface of the binding material at the upper end of the support and fixed to the support, and a fixing plate that is erected and placed on the binding material at the upper end of the support. a substrate interposed between the ends of the roof panels butted together and fixed to the ends of the roof panel, and a screw passing through the core material of the end of the roof panel that is in contact with the substrate on at least one side of the substrate; Because the shaft is protruding, if the upper fixing plate is fixed to the binding material and the roof panel is laid in alignment with the board, the board will position the roof panel, so the roof panel will need to be accurately placed in the predetermined position. It has the effect of simplifying the roof panel installation work. In addition, since the work of fixing the fixing plate to the support and the work of fixing the board to the roof panel can both be done from below the roof panel, there is no need to climb up on top of the roof panel and join the roof panels. Work safety is increased, the working posture becomes comfortable, and work efficiency is improved. In addition, the joint metal fittings of the present invention do not protrude from the top surface of the roof panel, and
Since it is not necessary to drive nails from the top side of the roof panel, there is no need to form a convex part on the roof panel, and there is no uneven part on the waterproof sheet installed on the roof panel P. Cracks do not occur in roofing materials such as asbestos boards placed on the roof panel P. Furthermore, when the roof panels are joined from the upper side of the slope of the roof, where the end of the roof panel rests on the substrate and the joint with nails is relatively strong, and the joint is made with nails, Screw shafts are used to connect wooden panels only from the lower side of the roof slope, where force is applied downward along the slope of the roof and there is a high possibility of nails coming off, so both sides are fixed using screw shafts. Compared to the case where the joint fittings are manufactured in this manner, the joining fittings can be manufactured at a lower cost without impairing the joining strength.
