PROBLEM TO BE SOLVED: To provide an edge-of-eaves part structure capable of easily carrying out work of an edge-of-eaves section with high degree of accuracy and ensuring the strength of the edge-of-eaves section without causing any problem such as weight increase, complication of a structure or the like. SOLUTION: The edge-of-eaves part structure 1 is constituted by a member having a hollow section of a bent and molded metal plate to make an edge-of- eaves purlin 5 as a member having light-weight with high strength capable of also ensuring fire resistance efficiency without causing any secular change. Durability and fire resistance performance of the edge-of-eaves section is improved, at the same time, there is no need to enlarge a sectional area of the edge-of-eaves purlin 5 or increase the number of bearing members, and strength of the edge-of-eaves section is ensured without causing any problem such as weight increase of the edge-of-eaves section, complication of the structure or the like. The edge-of-eaves purlin 5 is used as the member having light-weight with high strength to improve accuracy of work and work efficiency in a construction site of the edge-of-eaves section. |
