Spelsberg: solutions for concrete construction

Concrete is the basic construction material for many structures. Whether for functional or residential buildings, the efficiency of concrete construction is well-regarded in both fields. The short construction time combined with the high level of prefabrication argues in favour of using concrete. However, in comparison with other construction techniques, especially well-planned and effective electrical installation is important here.

Spelsberg's solutions for concrete construction offer just that. They are suitable for installation in both site-cast and pre-cast concrete. The switch and socket boxes, lightweight concrete boxes, installation boxes, universal luminaire installation housings, and wall and ceiling transitions from Spelsberg's IBT system can be easily attached to formwork before the concrete is poured. The especially high strength and stability of the IBT products seals their interiors safely from the concrete and ensures high positional stability.
Spelsberg developed the IBTronic system for easy and convenient integration of halogen or LED lights, loudspeakers and high-quality electronics such as KNX components or transformers in concrete ceilings. Patented support strut technology ensures that the housings can be safely used in both horizontal and vertical formwork. These and other technologies for concrete construction provide versatile and solid solutions for electrical installation in all sorts of structures.

Sturdy construction

The IBT range from Spelsberg was used in the renovation of buildings in the old town of Dresden. Historic facades combined with 21st century installation solutions. 

Case studies Concrete Construction

Einkaufszentrum Limbecker Platz 1

The IBT series is specially designed for use in concrete and ensures optimum installation of high-quality technical equipment in both site-cast and pre-cast concrete. Receptacles and ceiling sockets, connection boxes and other installation equipment must be attached to the formwork before the concrete is poured. The patented sealing mechanism – a membrane encloses the conduits entering the box – ensures strain relief and watertightness for the components in the IBT junction and connection boxes. Patented support strut technology ensures that the housings can be safely used in both horizontal and vertical formwork. The struts hold the box in the right position, even under extreme pressure, while the concrete is being poured.
Spelsberg's solutions for concrete ensure the service of the high-quality electrical equipment in open spaces, hallways and more than 200 shops.

Robust construction for historic facades

Modern, 21st-century installation solutions are hidden behind these historic facades in Dresden's old town. The Quartier II building complex directly adjoining the Frauenkirche and the Cosel Palace is equipped with products from Spelsberg's IBT concrete installation series. 

Quartier II in der Dresdner Altstadt

The three prominent baroque houses were renovated at a total cost of around 28 million euros. The six- and seven-storey buildings house shops, restaurants, offices and apartments. Their varied uses call for a versatile electrical installation, so the rugged, long-lasting products from Spelsberg's IBT series were used in the renovation. For example, there are switches and receptacles in the concrete walls and ceilings. With a uniform grid, they make it possible to line up boxes so that any number of switch boxes and receptacles can be installed.
