It's time to build a greenhouse with your arms. Because you will not do it yourself.
This requires very little: the desire and hands from the right place.
Greenhouse 9 * 3 * 2.2
Installation of greenhouses took 8 hours. For one day it's quite jealous.
Instruments:
Bulgarian, welding machine, level, tape measure, angle 90, clamps.
How to calculate the arc:
I took 6m. pipe 40 * 20 * 2
L = ПR / 2 = 3.14 * 3 (width of the greenhouse) /2 = 4.71
The arc length is 4.71 m.
The length of the pipe is 6 m.
6-4.71 / 2 = 0.645 m.
On 0,645 m. It is necessary to leave on edges, and further to begin to bend a pipe so you will receive an equal semicircle.
Materials:
Pipe 20 * 40 * 2 90 m.
Pipe 20 * 20 * 1.5 48 m.
Armature * 6 18 m.
Hinges 6 pcs.
Handles 3 pcs.
Primer 2.8 liters.
On 10/10/2017 the cost of the frame of the greenhouse cost me 5000 UAH. not counting the film or polycarbonate.
Good luck in building!
