Bodenarm

Bodenarm is a German term that translates to "bottom arm" in English. It refers to a type of armature or reinforcement used in masonry construction, particularly in the construction of vaults, arches, and domes. The term is derived from the German words "Boden" meaning "bottom" and "Arm" meaning "arm" or "support."

The bodenarm is typically a horizontal beam or bar that is placed at the base of a vault or arch. Its primary function is to provide additional support and stability to the structure. This is particularly important in large-scale masonry projects where the weight and span of the structure can be significant. By distributing the load more evenly, the bodenarm helps to prevent the collapse of the structure and ensures its longevity.

The design and placement of the bodenarm are crucial factors in the overall stability of the structure. It is often made of materials such as wood, metal, or reinforced concrete, depending on the specific requirements of the project. In some cases, the bodenarm may be integrated into the overall design of the structure, while in others, it may be a separate element added for reinforcement purposes.

The use of bodenarm is a traditional technique in masonry construction, with examples dating back to ancient Roman and Gothic architecture. It continues to be used in modern construction, particularly in the restoration and renovation of historic buildings. Its effectiveness in providing structural support makes it a valuable tool in the construction industry.
