Stage 10 – Installation of the 2-inch bent PVC-pipe arches
During Stage 10 we will install and attach the arches onto the greenhouse wooden structure, as well as the pieces of lumber that will reinforce the whole roof after the 2-inch PVC arches are assembled. Next, the arch is positioned on the wooden structure (Photo 139). Three people are needed to lift the upper wooden structure with the arch bent upwards (Photo 140). Photo 141 shows the initial position of the bent PVC pipes attached to the 4-inch PVC columns (Photo 142).
We recommend using a 2-inch round metal clamp (Photo 143) to reinforce the connection between the bent pipes and the 4-inch PVC column. After laying all the arches on the greenhouse wooden structure, install the upper (Photo 144) and lower (Photo 145) pieces of lumber, so that the entire wooden roof structure is reinforced. Tied with galvanized wire (Photo 146), the 2-inch PVC arch is centralized on the main beam (Photo 147). The structure of the agricultural greenhouse with alternative materials is finished (Photo 148).
