Topic The lighting possible cupola is offered with the strength which it withstands moderate gale and rain and snow weight.Solutions Infrastructure material it consists of with the top end rail material 20 which installs on 10 for security guarantee and the infrastructure material, the infrastructure material, as on the median transparent strengthening resin board 11 is allotted, allots metal make renforcing plate 12 to longitudinal left and right of this strengthening resin board. The top end rail material applied wire mesh 22 on the base frame material of the metal and make had with the base material which transfers and the edge strip material which is allotted to the longitudinal left and right of this base frame material, the basic destal time motion the axis made the edge strip material, the base frame material of the aforementioned base material wear unrestrictedly, the edge strip frame material it has with the muscle intersecting 26 which provides in as needed place of 24 whose folding enclosing is possible and this edge strip frame material. Because edge strip frame material 24 becomes the handrail, top end rail material 20 it can walk the worker. Infrastructure material 10 raises the safety of walking. It can guarantee also lighting performance by transparent strengthening resin board 11. Choice figure Drawing 1
