Resin panel structure

A resin panel structure comprising:

• a fiber reinforced plastic upper panel extending in a horizontal direction;
• a fiber reinforced plastic lower panel extending in the horizontal direction installed below the upper panel;
• a fiber reinforced plastic core panel extending in the horizontal direction that is installed between the upper panel and the lower panel and joined to the upper panel and the lower panel, and includes an opening through which a portion of the upper panel or a portion of the lower panel is inserted;
• and
• a joining member that joins together (i) the upper panel or the lower panel that is inserted into the opening and (ii) the other of the upper panel or the lower panel, wherein
• the joining member is a continuous joining member that joins the core panel, the upper panel, and the lower panel at the opening,
• the core panel, the upper panel, and the lower panel are each in contact with the continuous joining member,
• an indented portion is provided to the upper panel such that the upper panel is indented toward a side of the lower panel and inserted into the opening, the indented portion having a bottom wall that faces the side of the lower panel and an inclined wall that faces a side of the opening,
• the joining member being a single continuous joining member that (i) joins the bottom wall of the indented portion with the lower panel and (ii) joins the inclined wall of the indented portion with the opening of the core panel, and
• the continuous joining member is disposed between an upper wall of the core panel and a lower wall of the upper panel and between a lower wall of the core panel and an upper wall of the lower panel.
