Relax on a large terrace in the shade of a wrought iron pergola? To afford this pleasure, Jean-Pierre Aupetit has done everything from A to Z: enlargement of the terrace, making the pergola and furniture.
The terrace built at the same time as the house was showing signs of deterioration. The repair was an excellent opportunity to enlarge it. "She was not big enough to put a table and the plancha "explains Jean-Pierre Aupetit.Faced south, the facade also required sun protection worthy of the name: so awning, pergola or veranda?
Our reader quickly decided: "In addition to the budget and ease of realization, we were afraid of losing natural light inside the house by opting for a veranda."As for the blind without charm, it is eliminated too.Therefore a pergola is retained.
The second question is about type of material to use and, again, the solution was quickly found: "I could have built it out of wood, but I like to work with iron."His choice stopped, he immediately goes to work, first the plans, then the implementation:" I designed it in two identical parts that I assembled. It has a beautifully curved shape with small scrolls to finalize each bar. "
" I always draw my achievements before starting. I do not always respect the plans, but it gives me an idea of the result. "
Before building: demolition and consolidation.
"I removed the old tile, then opened the cracker cracks caused by ground movements, scraped them, then restocked with mortar before applying a new plaster"
Solid foundations (runners) are made for the extension and to reach the height of the existing terrace, concrete blocks are sealed in two rows.
The excavation is filled with stones by reserving 10 cm for the concrete slab dosed at 350 kg / m3.
Before pouring the slab, the formwork is put in place on the concrete blocks: "To secure them to the terrace, I used concrete bars (Ø 8 mm) embedded in the old terrace and embedded in the fresh concrete. "
A sand bed (4 cm thick) is prepared to receive the square gravel slabs. The joints are then made with a polymer powder.
Traditional locksmith forces, the decorative pieces are shaped one by one.
Here, shaping round irons useful in the design of decorative balls.
For the design of the pergola, our reader uses traditional profiles: flat (40 x 3, 25 x 3 mm), round (Ø 10 and 6 mm), tubes (40 x 40 x 2, 25 x 25 x 2, 20 x 20 x 2 mm) and tees (30 mm). In all, more than 50 meters of iron.
The assembly is performed in two parts secured during the final assembly.
All the welds are cleaned and ground, the irons are degreased and painted.
"Child, during the holidays, I was introduced to the technique of wrought iron at a blacksmith. It was with him that I learned everything".
The pergola is fixed to the wall with threaded rods (Ø 8 mm), chemically sealed.
The uprights, fitted with platinum, are held on the ground by expansion plugs and stainless steel threaded rods (Ø 8 mm).
The cover fabric, ordered to size, is held in the amount using tensioners.
Final touch with the furniture.
Our reader has built the oak garden table. The frame is mitered, with mortise and false tenons glued and pegged and blades are end tened and mounted in a groove in the frame of the frame.
Work yourself the iron... and the wood
For the pergola, our reader applies a principle which he does not derogate when he tinkers: " I arrange to be able to achieve everything. For the pergola, I only bought the hardware, the 6 meter long steel bars - which I partly cut to length for easy transport - and the cover fabric. "
For the rest, it's homemade making to start with the roof bars: six in all.
The difficulty lay in the curved shape and, of course, identical reproduction on each of the six bars:
"I drew a template on the ground, then I formed each bar cold using a 300 IPN in support. As and when, I presented the bar on the template until the shape matches."
According to the same principle, he creates all the decorative elements, volutes and decorative balls.
Everything is welded and screwed.
The pergola also benefits from a windbreak on the west side of the terrace made of wood "from hazel and chestnut stalks".
Final touch, an oak table: "as it stays out, rather than a massive deformable tray, I designed it with blades held by a frame".
Locksmithing or welding amateur
To turn into a metal worker or a welder is not given to everyone. However, these techniques are not inaccessible to the amateur. There are many courses that allow you to learn or improve. More or less long - from 1 hour to a full week - and of course more or less expensive, they are offered by major DIY stores or by approved training organizations (Ferrometal, Recycling Anduze, Renaud Forge...).
