<P>PROBLEM TO BE SOLVED: To provide a light-weight and strong construction panel without secular deformation, which can be used as an outer wall material, an inner wall material, a roof material, etc. of a building or a structure requiring fireproof performance and fire-resistant performance. <P>SOLUTION: In a construction panel A, a core material 3 made of synthetic resin foam is formed on a back surface of a metallic surface material 1 and male and female connection structures are formed at upper and lower end parts. A cover part 7 is formed from a lower edge 6 whose lower end is bent to the indoor side and distal end is projected upwards at the lower end part of the metallic surface material 1, and the construction panel A is formed by inserting, into the cover part 7, a lower reinforcement piece B2 of a reinforcement plate B formed in a roughly T-shaped cross section from a projection piece B1 in a roughly horizontal surface shape, the lower reinforcement piece B2 for which the outdoor side distal end of the projection piece B1 is suspended downward and an upper reinforcement piece B3 for which the outdoor side distal end of the projection piece B1 is projected upwards. <P>COPYRIGHT: (C)2012,JPO&INPIT |
