New Fair Hall Hamburg

No fear of big challenges

Around 100,000 square metres of roof area of the Hamburg exhibition halls were designed as barrel roofs with Lignotrend elements, some of which absorb enormous disc forces. Fire protection and room acoustics were also quite demanding in this construction project. The design of the halls themselves follows a modular principle of arrangement, which guarantees high flexibility as well as largely natural ventilation and the supply of daylight.

Configuration overview

Components used

  • LIGNO Acoustic Q3 classic  |  Roof component

    LIGNO Akustik Q klassik_Q3_150-210_rg0_s0_k50l_p0_al40g_625-105-20_FI-ä_gb_b-xy
    Installation top


    Whether the element is open or closed at the top is determined by the area of application. If, for example, the element is to be filled with fill on site as a storey ceiling or roof terrace (LIGNO Rippe Q3-x), its cavities are open at the top (feature _r0). To guide pipes at the top of the element, a cross grid (_r25, _r50) can be added to some superstructures. For roof superstructures, there is usually a flat closed finish _rg0 (LIGNO Block Q-x, LIGNO Block Q3-x or corresponding versions of LIGNO Akustik klassik).

    Installation top

    _rg0 Closed, without cross grid

    Statics


    The height of the load-bearing webs of the element is variable and determined according to static requirements from load and span. Within the framework of this configurator, the selection is limited to four height ranges. A more precise definition is made later during pre-dimensioning or verification with the LTB-x calculation programme. Bulk volume and/or necessary space for installations can also be decisive for the height.

    Statics

    _150-210 Low span

    Fire resistance

     

    If fire protection is required, an additional layer is added below the web area (for elements with strip profiles _z26, _z53, _z80, for elements with board profiles Akustik klassik _k50g). Their height determines the fire resistance duration of the cross-section from 30 to 90 minutes. The fire resistance must be statically verified. If there are no requirements, the standard versions _z0 or _k50l are to be selected.

    _z0 R0

    Cavity


    Panel designs with slat profiles and additional layer can be configured with an additional cavity (_p26, _p53) below the additional layer for installation guides, fixtures or to improve sound absorption. Cables laid there then do not penetrate the fire-protection layer. If required, the cavity is filled with insulating material (_p26mw, _p26ha) to improve acoustic absorption. If no cavity is necessary, the characteristic _p0 is selected.

    Cavity

    _p0 No cavity

    Room acoustics


    If the soffit of the element is to have a good sound-absorbing effect, the penultimate layer is configured as absorber _a50g. Otherwise, this layer is configured as a solid wood layer _a0.

    Profile


    The visible layer is profiled with joints. The code for profiling indicates in millimetres: Element width, strip width (rounded, from/to if applicable) and joint width (rounded) as well as a letter identification for variants, e.g. with chamfered strip edges or with additional height gradation.

    Note: Some profiles indirectly cause exclusions for other configuration options.

    _625-105-20 Slat profile

    Wood type

     

    Various wood species are available for the visible layer. For quality reasons, individual wood species cannot be configured for all profiles; for technical reasons, surface treatments are excluded for some wood species.

    Wood type

    _FI-ä Spruce with knots, A quality

    Treatment


    Depending on the type of wood, the optional application of a surface treatment is possible ex works. Individual colour finishes are always sampled for coordination. For elements in individual lengths, colour treatment is limited to max. 5 m length.

    Treatment

    _b-xy individual color treatment

    Structure


    The face is subjected to a brushing _gb as standard, which produces a stronger or weaker structure depending on the type of wood and makes the surface less sensitive to scratches.  Alternatively, a smooth sanding _gs can be carried out, or on request a bandsaw cut _grimitated.
