Nordbad Darmstadt

Sports pool in wood

Die eingesetzten Dachbauteile made of LIGNO® bestehen aus zu Kästen aufgelösten Massivholzquerschnitten, welche dem Raum Dynamik und Form verleihen.

Die Schwimmhalle hat eine Dachkonstruktion aus Holz. Die Unterseiten der Dachbauteile sind akustisch wirksam. Mit zusätzlichen Verkleidungsflächen aus Paneelen LIGNO® Akustik light an den oberen Wandbereichen perfektionierten die Raumakustikplaner die Ruhequalität.

Die Schwimmhalle betont durch die im Inneren verwendeten Naturmaterialien und die großzügige Verglasung ihre Nähe zur Natur, was für eine angenehme Raumatmosphäre sorgt.

Die verwendeten LIGNO® Block Q3 punkten in der Schwimmhalle mit ihrer Konfigurierbarkeit und sind nicht nur statisch und optisch hochwertig, sondern erfüllen auch alle raumakustischen und brandschutztechnischen Anforderungen.

Mit dem Naturmaterial Holz an Decken und Wänden entsteht in diesem Schwimmbad eine angenehme, warme Raumatmosphäre.

Die hellen Decken in Weißtannen sorgen in den Schwimmhallen für einen besonders naturnahen und angenehmen Schwimmaufenthalt.

Die multifunktionalen Dachbauteile von Lignotrend wirken als dominierendes Designelement in der Schwimmhalle und stellen eine ökologische, effiziente und nachhaltige Materialwahl dar.

Direkt an das helle Eingangsfoyer schließt ein massiver Gebäudekern aus Stahlbeton an, in dem unter anderem die Umkleiden und Sanitärbereiche untergebracht sind. Er unterstützt die Aussteifung der Holzarchitektur für die Dachlandschaft. Paneele LIGNO® Akustik light zieren hier die Decken und Wände aus Beton, erfüllen akustische Aufgaben und integrieren Schrank- und Türöffnungen.

Bei diesem Hallenneubau spielt Holz ein tragende Rolle und der Einsatz von viel Glas verbindet das Innere mit der umliegenden Natur.

Die hohen Decken sorgen für viel Weite im Inneren - ein Effek, der durch die fast wandhohe seitliche Verglasung noch verstärkt wird und dem Gebäude einen modernen und zugleich naturnahen Charakter verleiht.

Darmstadt is a city of swimmers, with a total of ten swimming pools available to its citizens and thus a comparatively large range of facilities. Many other municipalities are closing their indoor swimming pools, but Darmstadt is investing in maintaining its swimming facilities. The old Nordbad, built in 1971, was getting on in years and had to be demolished. After winning the competition, Sacker Architekten from Freiburg built a worthy replacement on the same site. This resulted in a new indoor swimming pool building next to the existing one, in which wood plays a supporting role. Thanks to the individually configurable cross laminated timber roof components from Lignotrend, there are also the best acoustics and aesthetic room quality. Holzbau Amann from Weilheim was the company responsible for the carpentry work.

Configuration overview

Components used

LIGNO® Block Q3 | Roof component
Product code: LIGNO® Block Q3_310-450_rg0_s0_z0_p0_a50g_625-18-6_WTE_gb_buv
To configurator To product page
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® Acoustic classic).
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
_310-450 Large 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.
Fire resistance
_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.
Room acoustics
_a50g Integrated absorber
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.
Profile
_625-18-6 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
_WTE Silver fir knotless, economy
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
_buv UV-protection stain
