Old vegetable shed transformation method
First, do everything possible to raise the ridge height. For each additional 10 cm of the old shed, the maximum temperature in winter can increase by 1-1.5°C. The method is to dig the ground in the shed 15-20 centimeters, or release the wire and lift the post up 15-20 centimeters. Second, adjust the shed surface arc. In the past, the old sheds were generally flat, and the middle two rows of columns should be properly raised so that the sheds could be curved. Third, increase the slope elevation angle. When changing the back slope, lift the rear column upside down, or dig the climbing wood on the back wall to increase the elevation angle. Fourth, backslopes and gables soil, increase the thickness of the wall. After transformation, the ridge height can reach more than 3 meters and the wall thickness is more than 2 meters. The conditional replaceable steel skeleton can be used.
