PROBLEM TO BE SOLVED: To provide an eaves back fire preventive structure that eliminates the need to provide a fire preventive structure to the whole eaves edge part each time the projection length of the eaves edge part is changed according to a plan for a building.SOLUTION: At a certain position of an eaves edge part 10, projecting outward from an outer wall 4 of a building body, in a projection direction of the eaves edge part 10, a fire preventive line L is formed which is made of an incombustible material provided continuously from a roof board 8 of a roof 5 to the outer wall 4. Consequently, eaves back fire protection can be achieved without reference to the projection length of the eaves edge part as long as the fire preventive line is secured, and the whole eaves edge part need not be formed into a fire preventive structure each time the projection length of the eaves edge part is changed according to a plan for a building. |
