Fallrohrdurchmesser

Fallrohrdurchmesser refers to the diameter of a downspout, a vertical pipe that carries rainwater from a gutter to the ground or a drainage system. The size of the fallrohrdurchmesser is a critical factor in the effective drainage of rainwater from a roof.

Choosing the correct fallrohrdurchmesser depends on several factors, including the size of the roof area that drains into the gutter, the expected rainfall intensity in a particular region, and the pitch of the roof. Larger roof areas and areas prone to heavy rainfall require downspouts with larger diameters to prevent overflow and potential water damage to the building's foundation or walls.

Standard fallrohrdurchmesser sizes vary depending on regional building codes and the materials used for the downspout. Common diameters for residential buildings might range from 80 mm to 100 mm, while larger commercial or industrial buildings may require significantly larger diameters. The material of the downspout, such as PVC, aluminum, or galvanized steel, can also influence the available standard sizes.

An inadequately sized fallrohrdurchmesser can lead to several problems. If too small, it can become clogged easily with debris like leaves and twigs, restricting water flow and causing gutters to overflow. This overflow can lead to erosion around the building's foundation, damage to landscaping, and water ingress into basements or crawl spaces. Conversely, a fallrohrdurchmesser that is excessively large might be an unnecessary expense and may not offer significant functional advantages over a correctly sized, slightly smaller option. Proper calculation of the required fallrohrdurchmesser is essential for a well-functioning and protective rainwater drainage system.
