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.
Claims4
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.
