1 Project s fiche Menuiserie Bechoux 14 by 28 metre steel span Menuiserie Bechoux was looking for a high-quality workshop for its joinery business. It was to be a Sigma building 14 m wide, 28 m long and 3.5 m high. The whole interior of the building is free from steel columns or pillars and can therefore be used to the fullest extent for storage or workshop space. Customised finish The building is based on our Sigma model, but just like any Frisomat building, it can also be altered and extended by the client. Thus we built in two large sectional doors (4x4 and 3x3) here to enable large machines to drive in and out. A man door as staff entrance and three windows (1x1) in the side wall provide pleasant working conditions. A rooflight over the full length of the building brings natural light on the inside. Assembly in under four weeks Thanks to the unique Meccano system we were able to build really fast for Menuiserie Bechoux: from foundations to the rooftop in less than four weeks. The fully integrated production, delivery and assembly process guarantees very rapid construction. 25/02/2014 Frisomat Case study project fiche Menuiserie Bechoux 1/5

2 Wall insulation 1. Steel columns - Sigma section (Σ320), steel grade S390GD+Z, galvanised (275 g/m²). We use this high-quality cold-rolled steel as standard in all our steel industrial buildings. 2. Glass wool insulation - The mineral wool is 130 mm thick and boasts the following insulation values: Rc=3.0 m²k/w (thermal resistance), U=0.33 W/m²K (insulation value) and L=0.043 W/mK (thermal conductivity). 3. Minimal cold bridging mm insulation thickness, exceeds the height of the liner tray (90 mm) in order to prevent cold bridging. 4. Steel wall cladding - Trapezoidal sheets, TR45 type. Steel grade E , S280GD+Z275, galvanised (275 g/m²). Finished in RAL 7022 colour, with a polyester coating (25μm). 25/02/2014 Frisomat Case study project fiche Menuiserie Bechoux 2/5

3 Foundation 1. Steel columns - Cold-rolled sigma-section steel columns (Σ320), steel grade S390GD+Z, galvanised (275 g/m²). This is the standard quality sample used for all our buildings. 2. Glass wool insulation - Mineral wool rated at W/mK lambda value and 0.33 W/m²K U-value (heat transfer coefficient). The wool is 130 mm thick. 3. Plinth - Triple layer plinth (core in 80 mm thick polystyrene, plus two concrete wall panels) to be attached to the foundation blocks. The plinth is 400 mm high and acts as formwork when pouring the concrete floor. Finish in sheet metal cladding over the full length of the plinth for extra strength and more attractive appearance. Insulation board extends below the floor slab which provides improved thermal insulation and optimum protection against water splashes. Steel columns attached directly to the attachment points of the foundation blocks, provided with self-drilling screws and expansion bolts. 4. Prefabricated foundation block - Concrete foundation block 670 mm high (260 kg x 650 mm base area) ensures correct positioning and attachment of the steel columns to the building foundations. The foundations are supplied by Frisomat. In order to generate sufficient bearing capacity a foundation calculation is required for both upward and downward forces. The quantity of concrete to be poured will be estimated on the basis of this. 25/02/2014 Frisomat Case study project fiche Menuiserie Bechoux 3/5

4 Nokstuk 1. Connecting piece - Steel connecting piece (hot-dip galvanised S235 steel 6 mm thick) at 22 pitch. Pre-made attachment points make the joint with the steel roof girders, purlins and roof purlin cleats. 2. Girder - Sigma section steel roof girders (Σ320, steel grade S390GD+Z, galvanised 275 g/m²). Provided with attachment points for rapid assembly of the ridge piece. 3. Z-purlin - Steel purlin (S390GD+Z steel, galvanised 275 g/m²) with 120 mm effective depth (Z120) and 1.5 or 2 mm thickness depending on application. They can be assembled over a single bay, two bays or multiple bays with overlaps depending on the imposed loads such as snow, wind and sand. Our engineers will perform a purlin calculation in advance. Have a look at the geometric features of our sections. 4. Steel roof sheets - Steel grade E , S280GD+Z275, galvanised (275 g/m²). The TR45 roof cladding is finished in RAL7022 and has a 25µm polyester coating. 25/02/2014 Frisomat Case study project fiche Menuiserie Bechoux 4/5

5 Gutter detail 1. Connecting piece - Steel connecting piece (hot-dip galvanised S235 steel 6 mm thick) with a moment-resisting (rigid) joint to transfer force between column and girder. Standard hole pattern for correct fastening of the column and purlin steel Sigma sections, and for joining to the C120 roof purlin cleats. 2. Roof gutter - Wall-hanging gutter, fastened to the wall cladding (TR45 panels) with 113 mm water depth, manufactured in 1 mm thick steel. This is 0.17 mm thicker than a traditional roof gutter for increased load capacity and extra-long service life. The outer edge is 15 mm lower than the inner edge to prevent it from overflowing inwards. 3. Glass wool insulation - The mineral wool is 130 mm thick (L=0.043 W/mK and U=0.33 W/m²K). 4. Steel wall cladding - TR45 Trapezoidal sheets in steel grade E , S280GD+Z275, galvanised (275 g/m²). Finished in RAL 7022 colour, with a polyester coating (25μm). 25/02/2014 Frisomat Case study project fiche Menuiserie Bechoux 5/5
