Abstract:
To provide a metallic building board that is provided with firm and secure cut-off performance, and connection structure of the metallic building board.SOLUTION: In a metallic building board, a male tongue 100 is formed by protruding a metal skin outward at an upper end of the metallic building board that is composed of a core material 1100 coated with the metal skin, a female groove 500 is formed by recessing the metal skin inward at a lower end, and when coupling metallic building boards adjacent to each other in a vertical direction by abutting a male tongue side first arcuate connection piece 130 and a female groove side first arcuate connection piece 530 of the other metallic building board on each other by fitting of the male tongue 100 and the female groove 500, a rear face side end edge 110E of a male tongue side first inclined plane 110 is formed so as to be placed at a front face side as compared with a female groove side connection joint bottom face 520. Since rain water (water droplets) blown up by wind from beneath passes over a triangular space part from the male tongue side first inclined plane 110 and reaches the female groove side connection joint bottom face 520, connection structure of the metallic building board can efficiently restrain immersion of the rain water to an indoor side.SELECTED DRAWING: Figure 4
