Formhohlkörper

Formhohlkörper is a German term that translates to "form hollow body" or "formwork hollow element." It refers to a pre-fabricated structural element used in construction, particularly in the building of ceilings and floors. These elements are typically made from concrete and are designed to be lightweight and to reduce the amount of on-site concrete pouring required.

The core function of a Formhohlkörper is to create a void or hollow space within a structural slab. This void is often achieved through the use of internal hollows or a shell-like construction. The element itself provides a load-bearing function, transferring structural loads. After installation, the remaining space within or above the Formhohlkörper is filled with concrete, creating a monolithic slab. This method significantly speeds up construction time and can lead to cost savings compared to traditional cast-in-place concrete slabs.

Formhohlkörper are commonly employed in residential, commercial, and industrial buildings. They are particularly advantageous in situations where speed of construction, reduced dead load, or improved thermal and acoustic insulation are desired. The manufacturing process allows for precise dimensions and quality control, contributing to the reliability of the final structure. The design of Formhohlkörper can vary, with different shapes and void configurations available to suit specific structural requirements and architectural designs.
