Abstract (en)
[origin: ES8405470A1] Described in a displacement body for forming cavities in concrete structures. The displacement body lends itself to simple and cost-effective production, is extremely light-weight and still capable of meeting stability requirements. In a preferred embodiment the displacement body consists of a grid structure (1) formed of intersecting longitudinal and transverse rods, and plastic sheets (2a, 2b) applied to both sides of the grid structure and connected to one another and to the grid structure by welding and/or heat-shrinking. Further described are structures formed under employ of such displacement bodies, as well as advantageous methods for making same.
