门板
摘要：
本发明提供一种门板，其能够在外侧板和内侧板的双重结构物中确保铰链安装部分的强度。在外侧板(21)和内侧板(23)的双重结构物中，内侧板(23)的铰链安装面部(48、49)通过其周围的加强凹槽部(48c、49c)而在结构上得到加强，并且固定在外侧板(21)和内侧板(23)的一侧部的加强板收纳凸部(29a)之间的内部加强板(41)的铰链安装凸部(43、44)，通过其周围的加强凹部(43c、44c)而在结构上得到加强。所述内侧板(23)的加强凹槽部(48c、49c)与内部加强板(41)的加强凹部(43c、44c)配合，从而在结构上得到强化。能够确保作用有门板(20)的自重的铰链安装面部(48、49)和铰链安装凸部(43、44)的强度。
摘要（英）：

Disclosed is a door panel that can guarantee the strength of the hinge mounting parts in a double structure with an outer plate and an inner plate. In the double structure having an outer plate (21) and an inner plate (23), hinge mounting surface parts (48, 49) of the inner plate (23) are structurally reinforced by reinforcing concave groove parts (48c, 49c) around them. The hinge mounting concave parts (43, 44) of an inner reinforcing plate (41) affixed between the outer plate (21) and a reinforcing plate accommodating convex part (29a) on one side of the inner plate (23) are structurally reinforced by reinforcing concave parts (43c, 44c) around them. The reinforcing concave groove parts (48c, 49c) of said inner plate (23) and the reinforcing concave parts (43c, 44c) of the inner reinforcing plate (41) are fitted together to provide structural strength. The strength of the hinge mounting surface parts (48, 49) and the hinge mounting convex parts (43, 44) on which the weight of the door panel (20) itself acts can be guaranteed.
