Canopies made of metal - the simpler, the better
Due to the fact that at home or even in an equipped, but unprofessional workshop somewhere in the garage, it is difficult to process metal, especially if you need to bend it, usually the structures from it are assembled as simple as possible.
Of course, with this, the aesthetics are lost, but it is always neglected in favor of reliability and durability. The basis of all - supports from a pipe diameter of 80 mm and a length of 2.5-3 meters, in an amount of 4-6 pieces. Also, we need an identical number of trimmings of a pipe with a diameter of 83 mm, they can be taken from waste.
The wall thickness of the canopy tube must correspond to the expected load proportional to the size of the structure.
We prepare the pad, carefully leveling it and ramming it, along the perimeter with a swarm of grooves for pipes, in 2 rows of 2 or 3 pits with a depth of 50 centimeters, so that an even rectangle turns out. Then we prepare the pipes. We take our supports and insert them one end into the trimming so that the "eighties" do not protrude from the other side.
Now it is possible to think, because canopies from a metal profile can be fixed or dismounted .If we choose the first option, we connect the trimmings with the supports by welding, if the second one is bolted, drill the holes in the upper part of the trimmings, drilled the supports together. Now we establish the received racks in pits and fill it with pre-prepared concrete mix.
We collect a light canopy from the metal profile with our own hands
So, we already have a platform, pits and supports, it only remains to figure out how many skates there will be in the canopy and how to build them, since working with metal is much more difficult than woodworking. Variants of installation of cross-pieces are a little. For the dismantled canopy - weld to the square profile on one side of it short cylinders of a pipe diameter of 83 mm, which will need to drill through holes.
Cylinders must be positioned so that they can be used to fit the profile onto the supports. Such a design should be two, to connect two rows of racks. On the holes in the fixing cylinders we drill the same at the upper ends of the supports and let the bolts pass through both pipes. Instead of cylinders to cross-pieces, plates with holes can be welded, but this connection is less reliable.
It is logical that if we make the canopy non-collapsible, then just weld cross-bars to the posts and throw this problem out of our heads. As for the rafters, they can be assembled from Tural Duralumin or from an aluminum corner. It is also advisable to use a wooden beam, but if you want to collect a canopy from the metal profile with your own hands without wood, this option disappears.
T-rafters can be of arbitrary shape, although it is difficult to bend this arch in the arch, it's easier to do this with a corner, making triangular notches in one of the shelves at even small intervals.
Roof installation on the profile structure
Polycarbonate has proved to be the roof for the canopy, it is this material that stops and even the market pavilions. Mount it on a pre-prepared frame is very simple, it is enough to drill the holes between the stiffeners and insert bolts with washers and rubber gaskets under them.
What is good about polycarbonate - it bends well, but if the roof is single or double-sided, you do not need to bend anything, flat sheets are laid on the prepared rafters.
When installing the rafters, make sure that the roof of the canopy is wider than the platforms between the supports, forming on the edges of the canopies from which, during the rain, the water streams would drain as far as possible from the concrete foundation of the racks. Around the canopy it is desirable to make a channel with rainwater drainage, so as not to flood the supports of the .
If you want to build a windshield for a canopy, in the event of parking under the car, a crate of the same square profile that was used as support rails is attached to the posts, and the material used for the roof,polycarbonate.
