Disclosed is a scaffold installed within a large structure such as a pressure vessel or a tank of a ship, and an insulation system construction method using the same. The scaffold for use in performing desired work within a large structure includes a supporting structure installed adjacent to both side surfaces and a top surface of the large structure, and a carrying unit installed movable along the supporting structure to allow materials to be carried or to provide a working space for a worker thereon, wherein the supporting structure is installed to be movable along a wall surface of the large structure.

The system of claim 1, wherein the top wall comprises two or more top wall sections, each of which comprises an interior surface, wherein the interior surfaces are angled with each other. 4. The system of claim 1, wherein each or either of the first side section and the top section comprises two or more segments, each of which extends at an angle with respect to neighboring one thereof. 5. The system of claim 1, wherein the top section generally extends in a horizontal direction perpendicular to the first direction. 6. The system of claim 1, wherein the first side section is configured to move substantially parallel to an interior surface of the first sidewall when the scaffolding moves in the first direction. 7. The system of claim 1, wherein the top section is configured to move substantially parallel to a surface of the top wall when the scaffolding moves in the first direction. 8. The system of claim 1, wherein the scaffolding comprises a spacer interposed between and engaged with the first side section and the first sidewall, and wherein the spacer is configured to maintain a distance in a horizontal direction perpendicular to the first direction between the first side section and the first sidewall while the scaffolding moves along the first direction. 9. The system of claim 1, wherein the first side section comprises two substantially parallelly extending portions, and wherein the first carrier is configured to be interposed between the two substantially parallelly extending portions. 10. The system of claim 1, wherein the first carrier rail extends generally parallel to interior surfaces of the first sidewall, the second side wall and the top wall. 11. The system of claim 1, wherein the first sidewall comprises an interior surface, wherein the structure further comprises a partly assembled structure formed on the interior surface, wherein the partly assembled structure comprises a metallic plate and an insulation material interposed between the metallic plate and the interior surface, wherein the metallic plate comprises a plurality of metallic pieces that are liquid tightly coupled together so as to form the metallic plate. 12. The system of claim 1, wherein the structure further comprise a bottom wall, wherein substantially all of interior surfaces of the first sidewall, the second sidewall, the bottom wall and the top wall is made of metal. 13.

The system of claim 13, wherein the first sidewall, the second sidewall, the top wall and the ground define the interior space. 15. The system of claim 1, wherein the structure comprises a bottom wall generally opposing to the top wall and connected to the first sidewall, wherein the first sidewall, the second sidewall, the top wall and the bottom wall define the interior space. 16. The system of claim 1, wherein at least one of the plurality of scaffolding rails is fixed to the first sidewall or a corner formed by the first sidewall and a neighboring wall thereof. 17. The system of claim 1, wherein the scaffolding comprises a bottom section extending substantially parallel to the top section. 18. The system of claim 17, wherein the first carrier rail extends from the bottom portion of the first side section to the bottom section such that the first carrier moves along the first carrier rail from the bottom portion of the first side section to the bottom section. 19.
