Abstract

A resin panel structure capable of improving positioning precision of a resin panel is provided. A resin panel structure includes a fiber reinforced plastic upper panel, a fiber reinforced plastic lower panel disposed below the upper panel, a fiber reinforced plastic core panel 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 into which a portion of the upper panel or a portion of the lower panel is inserted, and a joining member that joins the upper panel or the lower panel that is inserted into the opening, and the other of the upper panel or the lower panel, together.

First claim

What is claimed is:

1. 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, and
the joining member being a single continuous joining member that (i) contacts and joins the bottom wall of the indented portion with the lower panel and (ii) contacts and joins the inclined wall of the indented portion with the side of the opening of the core panel.

2. The resin panel structure of claim 1 , wherein a plurality of beads running along one direction are provided to the fiber reinforced plastic core panel.

3. The resin panel structure of claim 2 , wherein the opening is provided between adjacent beads of the plurality of beads.

4. The resin panel structure of claim 1 , wherein:
a through hole is formed at a join portion where the indented portion and the lower panel are joined together so as to pierce through in an up-down direction.

5. The resin panel structure of claim 2 , wherein:
a through hole is formed at a join portion where the indented portion and the lower panel are joined together so as to pierce through in an up-down direction.

6. The resin panel structure of claim 3 , wherein:
a through hole is formed at a join portion where the indented portion and the lower panel are joined together so as to pierce through in an up-down direction.

7. The resin panel structure of claim 4 , wherein the joining member is filled between the upper panel and the lower panel so as to span from the opening across to the through hole.

8. The resin panel structure of claim 5 , wherein the joining member is filled between the upper panel and the lower panel so as to span from the opening across to the through hole.

9. The resin panel structure of claim 6 , wherein the joining member is filled between the upper panel and the lower panel so as to span from the opening across to the through hole.

10. The resin panel structure of claim 2 , wherein:
the plurality of beads are disposed extending from a first end of the core panel toward a second end of the core panel;
a portion of the plurality of beads terminates within the core panel; and
the opening is formed at a flat face portion at a side of the second end of the core panel beyond a terminal portion at which the portion of the plurality of beads terminates.

11. The resin panel structure of claim 1 , wherein 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.

12. The resin panel structure of claim 1 , wherein the continuous joining member fills the opening between the fiber reinforced plastic core and the upper panel or the lower panel that is inserted into the opening.

13. 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.
