Three-field sports hall

School sport can also be done quietly(r)

Dachelemente mit Akustikprofil aus Holz | Betonwand | Sporthalle Dresden Cotta

The three-field hall has a total sports area of 45 m x 27 m with a clear room height of 7 m. Its supporting structure consists of a reinforced concrete structure on which 32 m long wooden trusses have been placed and support the roof without columns. The roof supporting shell itself consists of cross laminated timber box elements, which as the hall roof fulfil several tasks in one component: In addition to the static function as bracing shell, there is also the room acoustic function.

Configuration overview 

Components used 

  • LIGNO Akustik light  |  Ceiling cladding  

    Produktcode: LIGNO Akustik light 3S_62_a50g_625-23-8_WTE_gb_b0
    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 

    _WTE Silver fir, economy 

    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.

    _625-23-8 Slat profile 

    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.

    Structure 

    _gb Brushed 

    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 

    _b0 untreated 

    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.

  • LIGNO Akustik Q3 klassik  |  Roof component 

    Produktcode: LIGNO Akustik Q3 klassik_230-290_rg0_sze_k50g_p0_al40g_625-105-20_WTE_gb_b0
    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 

    _230-290 Medium 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.

    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.
