PROBLEM TO BE SOLVED: To provide a built-up method of a single layer lattice dome connecting PCa members and PCa joint sections to each other with flexible steel materials having low flexural rigidity by executing a PC binding method to connect and assembly. SOLUTION: An anchorage section 3 is provided to the upper surface or the lower surface of the end of each of precast concrete members 1, at the same time, a sheath 5 passing through the anchorage section 3 from the end face of each of the precast concrete members 1 is buried in advance, a precast concrete joint section 2 is prepared, and the sheath 5 is buried inside the joint section 2 in a state of penetration in arrangement coinciding with the sheath 5 of the anchorage section 3 of each of the precast concrete members 1. The precast precast concrete members 1 butt each other through the joint section 2, steel materials having low flexural rigidity such as strand 7 or the like are commonly inserted into both sheaths 5, and post tension is introduced to the steel materials to bind, connect and assemble.
