The membrane used for this cover has a polyester fiber base with PVC coating on both sides. With an initial prestretch carried out in the factory before applying PVC induction, deformations due to tension are reduced, which provides dimensional stability.
The tarpaulin anchoring and tensioning system used consists of a special aluminum profile around the perimeter of the tarpaulin, which is fixed and tensioned to the structure by means of stainless steel buckles, which allow a fine regulation of the tension on the edge, to give the canvas the proper tension in each area.
It is a roof made up of 8 central bodies in a warped curved shape, measuring about 24.75 x 8.00 m, made up of alternate arches of different curvature. The warped shape is achieved with patterns defined by a specific software program, joined with welds by pressure and heat by high frequency. With fixing and adequate tensioning of the canvases around the perimeter, the necessary tension can be given to the membranes with enough clearance to fit the actual measurements of the structure.
CARING FOR THE DETAILSIn all our projects we seek to respect the design or the initial idea of the architects or promoters as much as possible. In this case, we provide the improvement of the design of the details of anchors, tensioning system and textile water evacuation gutters, without compromising the cleanliness of the result.
