DE3814030A1 - Foam steel - Google Patents

Abstract

An innovative way of utilising free steel capacities is sought in order not to lose steel sites and not to lose earlier investments in capital and know-how, work and prior human achievements. Foam steel as a structural composite material has qualities which are equivalent to the strength and lightness of styropor, but allow precise processing. This at the same time provides innovative applications.

Description

Everyone knows the firmness and lightness of styrofoam, Honeycombs and egg boxes and their strength. Sandwich construction is known for the walls of airplanes and ships. However, this is almost exclusively fiber reinforced plastics.

There is one for new applications of available steel capacity another solution is conceivable, with thin steel sheets as supports material can be used.

The sketch shows

Fig. 1, the "honeycomb" and

Fig. 2 details in section.

Fig. 3 shows the starting sheet.

The base plate ( 1 ) is first provided with many depressions ( 2 ) which are produced by pressing processes.

The arrangement of the troughs can be seen in Fig. 2 (honeycomb formation).

Two sheets are glued to each other in such a way that spherical cavities ( 3 ) are formed, as can be seen in FIG. 2. The connection can take place in a pressure chamber. At normal atmospheric pressure in the environment, a corresponding overpressure results in the cavities in real use, which, like bulging balloons, contribute to the rigidity.

Additional layers can be nested one above the other, whereby the counter-forms of the next layer can reach into the spaces ( 4 ) of the spherical spaces. This prevents shifts and additional stability.

Large bodies or load-bearing walls, insulating ceilings and floating trays, cantilevered domes and finished cells for biotope construction, stables, greenhouses or similar rooms conversions can be produced efficiently and inexpensively. Folding, stacking and transporting entire buildings is possible. Floating houses for marshland and insulating houses for deserts zones and cold areas are feasible and can be used on a mobile basis.

Claims (3)

1. Foam steel, characterized in that honeycombs are formed from steel sheets, the gas-tight ver connected under pressure, layered to layers and structures to honeycomb structures to walls or bodies. 2. Foam steel according to claim 1, characterized in that precisely shaped and precisely manufactured workpieces that can be gas-tight, light, rigid and self-supporting used as a wall or floating floor, as a lid or dome can be how to use them for innovative future projects also needed in remote places. 3. Foam steel according to claim 2, characterized in that the resulting structural elements are easily stacked and can be transported worldwide as modular systems on land, in the air and in swamps and riparian zones.
