1. Dimensions of the membrane
Size of the opening between the beams:
3119 × 5243 mm
Size of the membrane with allowance for eyelets:
3170 × 5290 mm (this information is not needed for the designer)
allowance: +25 mm around the perimeter
2. Beams
Size of the internal "pocket"
Side beams: 100 × 200 mm
length 3119 mm
Front beam: 80 × 200 mm
length 5243 mm
Material: glued pine
3. Roof slope
Height near the building: 2700 mm
Height at the edge of the terrace: 2600 mm
Drop: 100 mm
Angle: ≈ 1.95°
4. Shape of the membrane
Shape: diagonal origami tension
scheme: one corner raised, opposite lowered
Lift of one corner: +120 mm, asymmetric tension
5. Material of the membrane
Type: architectural PVC membrane
thickness: 0.8–1 mm
color: transparent
6. Printing
Pattern: Voronoi
color: anthracite
coverage density: 30–40 %
This provides:
- shadow
- but light passes through.
7. Eyelets
Type:
stainless steel
inner diameter: 16 mm
step: 400–450 mm
quantity: ≈ 28–32 pcs around the perimeter.
8. Rope
Type:
braided marine rope
diameter: 10–12 mm
material: polyester or hemp
color: natural linen
9. Lacing of the rope
Not just around the perimeter.
Scheme:
zigzag between the eyelets
╲╱╲╱╲╱╲╱
marine appearance of tension.
10. Offset of the membrane from the beams
The membrane does not lie on the beam.
Offset: 40 mm
Solution: spacer sleeve
11. Sleeve
Material: stainless steel or aluminum
size: Ø25 mm height 40 mm
a bolt passes through the sleeve.
12. Bolt
Type: stainless steel
size: M8 or M10
length: 100–120 mm
13. Ends of the beams
It is recommended to make a cut. Yacht aesthetics
angle: 30°
length: 120 mm
14. Additional ribs
To give the membrane shape: 2 aluminum ribs
profile: 40 × 20 mm
material: black anodized aluminum
15. Visual result
The structure should look:
- light
- stretched
- with a marine character
- with shadow from Voronoi.
