Heterogeneous slope roof with downward slope changing in the middle

摘要

PROBLEM TO BE SOLVED: To provide an upper roof panel and a lower roof panel whose downward slope changes in the middle while corresponding to the diagonal line limitation without any difficulty in strength and design in a heterogeneous slope roof whose slope changes in the middle of the downward slope. It is possible to stably support the joint portion by the support structure. SOLUTION: A downward slope slope changing portion 3 formed by the upper roof panel 1 and the lower roof panel 2 is provided at a joint portion between a downward slope upper roof panel 1 and a lower roof panel 2 joined to each other. In a heterogeneous slope roof in which the joint portion is supported by the support structure 4, an upper roof panel having an inclined upper surface 5a arranged on the upper end surface of the support structure 4 and on which the lower surface of the lower end portion of the upper roof panel 1 in the gradient direction is placed. It includes a connecting girder 5 and a lower roof panel connecting girder 6 having an inclined upper surface 6a arranged on an outer surface at the upper end portion of the support structure 4 and on which a lower surface at the upper end portion in the gradient direction of the lower roof panel 2 is placed. ..
