Rørinnstøpning

Rørinnstøpning is a method used in construction for embedding pipes within concrete structures. This technique is common in building foundations, walls, and floors where pipes for plumbing, heating, or electrical systems need to be permanently integrated into the concrete. The process involves placing the pipes in their desired positions before the concrete is poured. Support systems are used to ensure the pipes remain stable and in the correct location during the pouring and setting of the concrete.

The primary advantage of rørinnstøpning is its ability to create a clean, finished appearance without exposed pipes. It also offers enhanced structural integrity as the concrete encases and protects the pipes. However, this method requires careful planning and precise execution. Any errors in pipe placement or material choice can lead to significant problems, such as leaks or difficulties with future maintenance and repairs. The selection of pipe materials is crucial; they must be able to withstand the pressure and temperature of the wet concrete, as well as resist corrosion. Common materials include steel, copper, and certain types of plastic.

The installation process typically begins with the creation of a formwork for the concrete pour. Pipes are then laid out within this formwork, often secured to rebar or other structural elements. Expansion joints may be incorporated around the pipes to accommodate thermal expansion and contraction, preventing stress on the concrete. Once the pipes are secured, the concrete is poured and vibrated to ensure it fully surrounds the pipes and eliminates air pockets. After the concrete has cured, the formwork is removed, leaving the pipes embedded within the solid structure.
