Actions transmitted to the ground require underground foundations built with cement plinths. The anchorage system is however practical and allows the total disassembling thanks to these alternatives ways:
1) separation between pipe drowned in the plinth and pillar or
2) use of a metal plate fixed by screw anchors on the concrete base.
A– Executed the excavation, do a first concrete underground layer just to have a datum plane.
B – At this point insert the anchorage pipe in the excavation oriented in the correct way. This pipe has an hole at its base which can be used to insert an iron rod, so to be strongly linked to the plinth. Complete filling the excavation with the cement. At finished work, the male end of the pipe – on which the greenhouse pillar will be bolted – must emerge beyond the countryside plan.
