PROBLEM TO BE SOLVED: To improve the safety by eliminating high lift work, to reduce the construction cost by remarkably reducing the working time of a crane, and shorten the work time. SOLUTION: A gable roof 1' is divided on both sides of a ridge to be assembled on the ground, and both side roof members 1, 1 are pivotally connected in the position of the ridge by a pivot pin 1n. Side walls 2, 2 are divided on both sides to be assembled on the ground, and the upper ends of both side walls 2, 2 are pivotally connected to the eaves ends of both side roof members 1, 1 by a pivot pin 2n. Both side roof members 1, 1 are hoisted to form an angled gable roof 1'. Both side walls 2, 2 are hung down and erected at the eaves ends of both side roof members 1, 1, and in this condition, both side roof members 1, 1 and side walls 2, 2 are restricted and fixed in the vicinity of the respective pivoted connecting positions through locking pins 1r, 2o to complete construction.
