Abstract:
A building panel comprises 2 parallel slabs separated by a layer of insulation. Each of a pair of planar plate-like lift wings has a 1st and a 2nd lift wing portion. Each of the 1st lift wing portions is penetrated by at least one through opening. A planar plate-like lift head defines a plane of symmetry orthogonal thereto. 1st and 2nd lift head portions are symmetrically disposed on either side of the plane of symmetry. Each lift head portion is penetrated by at least one through opening symmetrically disposed relative to the plane of symmetry. Each lift head portion is penetrated by at least one through opening symmetrically disposed relative to the plane of symmetry. The lift head is attachable to both lift wings when the 1st lift wing portions are orthogonal to the plane of symmetry. The lift head is detachable from both lift wings to eliminate thermal conductivity between the lift wings.
