Referring now to the drawings, the wall panelv I, comprises two spaced sheets 2 and 3, of metal, congruently arranged in spaced parallel relation. The margins of the sheets are folded twice, at serve as forms into which the pillars of cement 30 right angles, to 'give the panel ?at side andv end are cast about the juxtaposed ?ngers. faces in a width direction, and to form channel Still another object of the invention is to pro?anges 4, extending around all sides of the sheets, vide a wall panel as described, in which the‘ bondde?ning an inner peripheral channel 5.

Since the spacing pattern is ' it to compressively resist any force’ tending to - symmetrical with respect to the opposite sides separate thev sheets in the direction of the thick ness dimension of the panel. It is preferred to cast marginal tie wires in the panel, useful for reinforcing the poured con of the sheet’, there is no problem in matching the : ends of the sheet in setting up the panel. To fab-y ' ricate the panel, all of the ?ngers 9 of the sheet are bent out perpendicular to the plane of the sheet along the fold lines l3, by means of pliers or . crete mass which intersects the joints between " contiguous panels, in the wall. This is done by a special tool. The perpendicular ?ngers will be , 1 perforating ‘some or all of the collars I! in the 'in groups of four, one group for each ?nger unit, ~ 40 peripheral borderv of the spacing pattern, as in , two of which ?ngers will have their width dimen sioned parallel to the length edges of the sheet, while two will be parallel to the width edges.
