Structures used as greenhouse roof assemblies, greenhouse roof assemblies, greenhouse frameworks, greenhouses and greenhouse framework construction methods

摘要

Provided is a structure capable of reducing a lifting work amount and an assembly work amount at a high place. The structure 1 of the present invention includes a rectangular frame 11 that is horizontally disposed, a rectangular main beam 12 that is vertically disposed on the frame 11, and a palm member 13 that supports the main beam 12. It is constructed and can be assembled on the ground or the like. Therefore, by using this structure 1 as a greenhouse roof assembly, the roof assembly of the greenhouse, the shaft assembly of the entire greenhouse, and the amount of lifting work and assembly work when assembling the greenhouse are significantly reduced compared to the conventional one. It becomes possible.
