Metal shelter
Technical description
Metal structure
The shelter is composed of a 3 mm thick, folded profile steel frame assembled with bolts. The frame is hot-dip galvanized after cutting and machining in accordance with European standard EN ISO 1461. The structural concept allows shipping of shelters in kit form with floor and roof pre-fitted to the metal frame.
Kit height : 500 mm to 750 mm depending on the model.
An adapted element allows stacking of shelters during shipping.
Data sheet
A data sheet is realised confirming resistance of the shelter under the following hypothetical conditions :
Climatic load-bearing capacity :
- Wind : Zone 5, exposed site (extreme wind speed of up to 230 km/h). This zone covers the entire French mainland, including coastal regions and overseas territories).
- Snow : Overload of 200 kg/m2 which corresponds to zone 2B at an altitude of less or equal 1,000 m.
Operating load-bearing capacity :
- Nominal load : 1 000 kg/m2 on a 0,60 m length of wall and 150 kg/m2 on the central section.
- Possibility to increase these load-bearing capacities by incorporating floor strengthening elements.
These calculations were carried out in accordance with the following standards and regulations :
- Regulation NV65 of April 2000 (Ref AFNOR DTU P 06-002, rules defining the effects of snow or wind on constructions).
- Regulation CM66 (steel frame construction calculation sheet).
Floor panels
The floor panels are resting on and fastened to a metal frame. It is composed of :
- Ribbed, galvanized metal panels, thickness : 75/100 th
- Incompressible polyurethane foam insulation with ACERMI certificate and isolation class = 52 324
- CTB-H panels with a thickness of 22 mm and quality certificate delivered by the CTBA (furnishing and timber technical test centre)
- Glued floor covering, classification U2s P2 E 1/3 C2 delivered by the CSTB (construction technical and scientific test centre).
Roof
The roof is composed of polyester insulated monoblock panels with a thickness of 50 mm and edges
clad on all four sides. (Incidence +8 cm on length and width). It is connected to the metal structure with hidden and tamperproof bolts.
Thermal coefficient K = 0,48 W/m2.°C
Outside walls
The walls are composed of insulated panels of the "sandwich" type. They are composed of :
- Outside facing : corrugated sheet steel, thickness 5/10 th, colour RAL 9002
- Polyurethane foam insulation, thickness 40 mm or 50 mm with a volumetric weight of 40 kg/m2, fire resistance classification : M1
- Inside facing : corrugated sheet steel, thickness 6/10 th, white RAL 9010.
Thermal coefficient K :
- Panels with a thickness of 40 mm : K = 0,52 W/m2.°C
- Panels with a thickness of 50 mm : K = 0,43 W/m2.°C
Fire classification of sandwich panels : B - s3, d0 in compliance with European standard EN 13501-1.
Door
The door is made of anodised aluminium profile offering a free passage space 900 x 2,100 mm.
Filling panels identical to those of the walls.
3 tamperproof hinges.
2 anti-distortion plates.
The door is fastened to the metal frame in order to avoid all risk of movement or frame distortion.
Incorporation of all types of locks (surface or built-on).
Handling - Lifting
Four lifting points are incorporated into the top section of the shelter's metal structure. This system renders the used of a lifting winch unnecessary for on-site handling.
Floor anchoring
Four floor fastening brackets are included on the metal structure. These brackets are used to fasten the shelter to a concrete or metal base.
Name plate
A name plate is fixed to the outside of the shelter, at the bottom next to the door. It indicates the type and project reference and allows perfect tracking.
Cable passage
Four reserves are incorporated into the floor for the passage of supply cables (power, telephone, etc.).
Reserves for the passages of coaxial cables may also be installed in the walls or in the floor. Their dimensions are defined by the number of cables entering the shelter.
