GRADIENT ROOF STRUCTURE

PROBLEM TO BE SOLVED: To provide a wide attic space minimized in kinds of parts and having a high freedom of application. SOLUTION: A support wall body B having a load dispersing part on the bottom part along the peripheral part of a horizontal plane of structure A is circumferentially raised in a band shape, and the lower middle part of a gradient roof part C is supported by the support wall body B. The support wall body B is constituted by setting a main house panel 3 formed by connecting an upper frame 3a and a lower frame 3b arranged in parallel by a connecting frame 3C on the plane of structure A continuously. The lower frame 3b is formed as the load dispersing part in which two lip channel steels are arranged back to back. A rafter receiver 4, a hip rafter receiver 8, and a valley rafter receiver 9 are fixed to the upper frame 3a, and the lower middle parts of a rafter 4, a hip rafter 6 and a valley rafter 7 are fixed thereto, whereby the lower middle part of the gradient roof part C is supported. The lower end sides of the rafter 4, the hip rafter 6 and the valley rafter 7 are fixed to a wall girder, and the upper end sides are fixed to a corresponding member arranged opposite thereto through a connecting member.
