Rib (technique)
In technology , a rib is a piece of plate with which another, often flat component is made more stable against deformation . It is attached vertically to such a plate-shaped component, after which potential bending or arching out of the plane of the plate is reduced. Very often a rib is also placed between two parts of the body so that they can bend less against each other. The axis of reduced bending is perpendicular to the plane of the ribs.
In technical drawings , a guided in the ribs level interface not hatched. Since ribs are often very large in relation to the entire component, this avoids the impression that the component is very massive (large in volume and mass).
In civil engineering , e.g. B. in the construction of vaults, the vault ribs are not reinforcing, but independent and self-supporting components.
In heating and cooling technology , thin metal sheets are attached to power components for thermal contact with the air, which are also known as fins. Examples are power transistors , finned tubes, and finned heating and cooling sinks.
Two narrow plates are welded together to form a T-bar; Flexural strength of connection with rib reinforced.
Relative to the base plate, the vertical plate can already be seen as a rib.

In the sectional view on the right, the incision through the rib at the bottom left is not shown hatched (empty triangle).

- ↑ With the material pattern model , the cut is not made through a rib if possible, in order to prevent the knife or saw from slipping out.
