The aluminium- or wooden-frame tarpaulin-covered tent structures with conventional gable roof and arched polygon shape - manufactured with the required ancillary equipment - are perfectly suitable for covering multifunctional sports grounds, tennis courts and soccer fields, stables, horse boxes, swimming pools and skating rinks, or even for the storage and maintenance of airplanes.
We recommend our conventional gable roof tents for covering areas that do not require high clearance e.g. swimming pools, skating rinks or stables. These structures are made similarly to storage tents, only their ancillary equipment is different, which is prepared in accordance with the customer’s needs.
The clearance of our gable roof tents with a large angle of pitch as well as the clearance of the arched polygon halls is more than 12 meters, and can be extended longitudinally by instalments of 2 to 6 meters as required. Recommended for covering areas where high clearance is required due to ballgames, such as large-field soccer, tennis, basketball, handball and volleyball; additionally, these tents are perfectly suitable for the storage and maintenance of airplanes as well, since large width and height is required due to the large wings of airplanes.
Graboplan provides the following services with regard to the covering of stadiums:
COUNSELLING, CONTRIBUTION TO THE PLANNING
The advices of our experienced engineers and manufacturing specialists concerning the roof structural and anchoring requirements of the subsequent membranes (reduction of the amount of steel required for the primary supporting structure, concept design of secondary auxiliary supports on the main support) should be taken into consideration at the stage of concept planning.
DEVELOPING THE CONCEPT, FORM-FINDING
The ideal membrane shape is developed by taking the local conditions – structure, anchoring, meteorological loads, roof type – into consideration with 3D form-finding analysis.
Preparation of scale model: before finalising the concept, it is possible to prepare a life-sized model to eliminate occasional planning errors and technical solutions that wouldn’t work in practice.
SELECTION OF MATERIALS, DETERMINING METHOD OF ANCHORING
The strength, quality and type of the load-bearing material required for the given roof or facade cover can be specified on the basis of preliminary static calculations, after the assessment of material tests. The type of the membrane anchoring can be finalised on the basis of the selected material, the type of the primary support, and on the basis of the preliminary static calculations.
ESTABLISHING THE BUDGET
The budget for the roof or facade membrane cover of a project can be prepared in light of the materials and the anchoring method.
DATA PROVISION FOR AUTHORISATION PROCEDURE
We prepare the membrane drawings, data provision concerning dynamics and preliminary designs for the authorisation design documentation of the construction as agreed.
PREPARATION OF PRODUCTION PLANS
The manufacturing of the tensioned membrane and of the anchoring will be performed on the basis of elaborated plans approved by the customer.
PREPARING PRODUCTION PLAN AND ASSEMBLY CONCEPT
Simultaneously with the selection of materials will the preparation of the manufacturing technology and assembly concept start, which, among others, shall include the performance of tests before, during and after the production, the determination of product control processes, procedural and final inspections, manufacturing technology, welding processes, folding and packaging concepts, the manpower and machinery needs of the on-site assembly, and the elaboration of proper assembly technology.
Technology and manufacturing capacities adapted to the dimensions and technical requirements of the project, using state-of-the-art machines: CAD/CAM computer-controlled plotter, high-frequency welding machines (for PVC-, PE- and PU-coated materials), pressing machines (for PTFE- and silicone-coated and Tenara materials).
We arrange the delivery of ordered products to any part of the world with shipping by road, by air or by sea.
Our group of experienced mechanics will perform the assembly of our tensioned membranes in any country of the world, under the supervision of Graboplan project managers: our mechanics have IRATA certificates, they are qualified to perform work at height, to operate machinery, they have personal protective equipment and special equipment for assembly.
PREPARATION OF DELIVERY DOCUMENTATION
Preparation of as-built drawings, specifications of materials installed, technical data sheets, declarations of performance with product-related user-maintenance instructions.
