SANDWICH WALL CONSTRUCTION FORMED OF SPACED-APART SLABS WITH INSULATION IN-BETWEEN HAVING A HIGH CARBON CONTENT

Abstract

The invention describes the construction of more or less thin house walls, of which the load-bearing panels are stabilized in such a way that they have an insulating middle layer, the middle layer containing carbon, which is brought in as insulation material by means of suitable binders such as cement, geopolymers, resins or foams or glass. In particular, biochar mortars and biochar foams are used, which with the help of fiber reinforcement of the outer stone slices become self-supporting wall and facade elements, which are able to store more carbon than what is produced in the form of CO2, escaping into the atmosphere. Fiber-stabilized stone disks with an insulating middle layer based on pyrogenic or otherwise manufactured or extracted carbon are constructed symmetrically and dimensioned in such a way that they can absorb loads and buckling forces with a comparatively very low weight. For this reason, in addition to its high carbon content, the insulation material should preferably have sufficient tensile stability.

Description

[0023] One of the many possible embodiments is shown in FIG. 1. The figure shows two stone slabs (1) which are stabilized with one Carbon layer (2). An insulation layer (3) with a high carbon content is attached between the fiber-coated stone slabs. The insulation layer (3) has sufficient tensile strength so that the panels cannot buckle outwards. The sufficiently tensile-stable insulation layer (3) can be designed over the entire surface or, as shown in cross-section in FIG. 2, only over part of the surface, meaning that the stone slabs are prevented from buckling in the middle area. Both figures also show the load introduction intakes (4) above and below.

[0024] In FIG. 3 it is shown that the fiber-coated stone slabs are made in such a way that each of the slabs is made from two stone slabs with an internal carbon layer. In the middle there is an insulation layer (3) that has a high carbon content. The insulation layer (3) is loosely fitted or attached between the stone slabs and has no stiffening function.
