Abstract
A panel structure 30 includes a panel 40 having a first insertion hole 42, a reinforcement 50 having a second insertion hole 52, and a fixing member 70 having a shaft 71 inserted in the first and second insertion holes 42 and 52, and sandwiching and fixing the panel 40 and the reinforcement 50 in their thickness direction. The panel 40 has a higher thermal expansion coefficient than the reinforcement 50. A diameter of the second insertion hole 52 in a direction of thermal expansion of the panel 40 is larger than a diameter of the first insertion hole 42 in the direction.
Claims6
A panel structure, comprising:
- a panel having a first insertion hole;
- a reinforcement having a second insertion hole;
- a fixing member having a shaft inserted in the first and second insertion holes, and sandwiching and fixing the panel and the reinforcement in their thickness direction;
- and
- a coating formed to cover a surface of the panel and a surface of the fixing member, wherein:
- the panel has a higher thermal expansion coefficient than the reinforcement,
- a diameter of the second insertion hole at least in a direction of thermal expansion of the panel is larger than a diameter of the first insertion hole in the direction, and
- the fixing member moves together with the thermally expanded panel during thermal expansion of the panel such that damage to the coating is reduced during thermal expansion of the panel.
