Panel construction member and mounting structure thereof
Provided are a panel construction member and a mounting structure for the same that can be rigidly mounted to a building and for which the panel, after being mounted, has excellent flexural strength and flexural rigidity. A panel construction member 1 has a layered structure in which a core plate 4 is disposed between a pair of metal plates 2, 3 , wherein the panel construction member 1 is provided with a groove 5 that extends along at least one pair of edges of the panel construction member 1 , and an undercut portion 5 a that penetrates between the metal plates 2, 3 from the groove 5 . A rail member 6 is mounted in the groove 5 of the panel construction member 1 , and the panel construction member 1 is mounted to a ceiling or a wall by means of the rail member 6.
1. A panel construction member with rail members comprising:
a right-angled quadrilateral panel construction member having a layered plate structure in which a core plate is disposed between a pair of metal plates, wherein a groove is provided in a back surface of the right-angled quadrilateral panel construction member, the groove extending along four sides of the right-angled quadrilateral panel construction member, and an undercut portion is provided between the metal plates, the undercut portion being recessed from the groove toward a center of the right-angled quadrilateral panel construction member; and
rail members mounted to the back surface of the right-angled quadrilateral panel construction member, wherein the rail members are mounted to the right-angled quadrilateral panel construction member by engaging claw portions with the undercut portion,
wherein the rail members are connected to each other with a connecting metal fitting.
2. The panel construction member with rail members according to claim 1 , wherein ends of adjacent rail members are abutted to each other.
3. The panel construction member with rail members according to claim 2 , wherein ends of rail members are cut diagonally to the longitudinal direction of the rail members.
4. The panel construction member with rail members according to claim 1 , wherein ends of adjacent rail members are connected to each other.
5. A mounting structure of a panel construction member, wherein the panel construction member with rail members according to claim 1 is mounted to a ceiling or a wall by means of the rail members.
6. The panel construction member with rail members according to claim 1 , wherein the groove has four portions along the four sides of the right-angled quadrilateral panel construction member, and the rail members are mounted to each of the portions.
7. The panel construction member with rail members according to claim 1 , wherein the rail members include a pair of first rail members and a pair of second rail members,
wherein the first and second rail members have both end faces being perpendicular to the longitudinal direction of the rail member,
wherein the second rail members are shorter than the first rail members, and
wherein the second rail members are arranged between ends of each first rail members.
8. The panel construction member with rail members according to claim 7 , wherein ends of the first rail members and the second rail members are connected to each other.
9. The panel construction member with rail members according to claim 7 , wherein ends of the first rail members and the second rail members are connected with a connecting metal fitting.
