Abstract
Abstract A concrete plate assembly, e.g. as load carrying members or for building facades, comprises an inner concrete slab, an outer concrete slab spaced from the inner slab, and at least one main or stress-absorbing anchor embedded and interconnecting the slabs which are reinforced. The intervening space can be filled with an insulation and/or can constitute an insulating air space. According to the invention, at least one of the concrete slabs in the region of the connecting anchor, is provided with a closed reinforcing ring which lies in the plane of the slab, preferably midway of the cross section thereof, the anchor being embedded in the concrete within the reinforcing ring and preferably centrally thereof.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
115 words
A method of making a composite panel comprising the steps of: casting a first reinforced concrete slab in a horizontal formwork bed with tubular anchors projecting from said first slab; casting a second reinforced concrete slab in a horizontal formwork bed with convoluted wire reinforcing rings having a ring plane lying in the plane of said second slab disposed at locations corresponding to said tubular anchors, the convolutions of said ring lying transverse to said ring plane; and turning over said first slab upon the setting thereof and lowering it toward said second slab prior to the setting thereof and vibrating said anchors into the concrete of said second slab and into the rings thereof.
Claim 2
Independent Claim
115 words
A method of making a composite panel comprising the steps of: casting a first reinforced concrete slab in a horizontal formwork bed with tubular anchors projecting from said first slab; casting a second reinforced concrete slab in a horizontal formwork bed with convoluted wire reinforcing rings having a ring plane lying in the plane of said second slab disposed at locations corresponding to said tubular anchors, the convolutions of said ring lying transverse to said ring plane; and turning over said first slab upon the setting thereof and lowering it toward said second slab prior to the setting thereof and vibrating said anchors into the concrete of said second slab and into the rings thereof.
Claim 3
Dependent Claim
18 words
The method defined in claim 1 wherein said rings are secured to the reinforcement of said second slab.
Claim 4
Dependent Claim
30 words
The method defined in claim 1, further comprising the step of applying a layer of insulation on the second concrete slab while leaving openings at regions corresponding to said locations.
Claim 5
Dependent Claim
30 words
The method defined in claim 3 wherein said first slab is lowered to said second slab and held from contact with said layer to maintain an insulating air gap therebetween.
