PROBLEM TO BE SOLVED: To provide a prefabricated built-up structure wherein the connecting angle of a joint for connecting girder members can be continuously changed the variation in distance between the upper ends of the girder members opposed to each other with the variation of the angle can be made small, the selectable range of the connecting angle can be widened, a same component can be used for connecting sections having different connecting angles and reducing the number of components can be reduced. SOLUTION: In the prefabricated built-up structure arranging the girder members 4 in series on the upper side of a strut and connecting the ends opposed to each other of the girder members 4 through the joint 5, the joint 5 includes a connecting shaft 21 in the direction of the width placed on an extension line of the upper end edges of both girder members between the girder members 4 or a position in the vicinity of them, a holding bracket 23 forming an insertion-hole for the connecting shaft 21 in the front end and fixing the base side to the girder members 4 and a fitting bracket 25, and inclined edge sections 35 and 44 inclined to the lower end side of the base section from insertion-holes 22 and 24 sides are formed in the holding bracket 23 and the fitting bracket 25.
