Core structure for a sandwich structure for the production of construction elements, comprises two flat elastic foils, which are arranged one upon the other and connected with one another at connection points, and continuous openings

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent relates to a specially designed core structure used in sandwich panels for construction elements. It consists of two flat, elastic, and electrically conductive composite foils placed on top of each other, joined together at spaced connection points, each of which contains a continuous opening smaller than the point itself. The invention also covers a method to produce such lightweight core structures for use in, for example, building materials.

Patent Abstract

The core structure (1) for a sandwich structure for the production of construction elements, comprises two flat elastic foils (3, 4), which are arranged one upon the other and connected with one another at several connection points (5) that are spatially apart from each other, and continuous openings (6) introduced in the connection points. The respective cross-section of the openings is smaller than the cross-section of the respective connection points. The foils are composite foils and are electrically conductive. The connection points are adhering-points or welding points. An independent claim is included for a method for the production of a core structure for a sandwich structure for the production of light-weight construction elements.
