etc holding the panels 10 12 14 16 and 18 in their proper places together with the hooks 74 on the upper flanges 28 and 28a of the panels 12 and 16 and the clips 76 and 78 effective on the lower flanges 60 of the panel 20 the hooks 74 fitting in respective slots 66 act to prevent the forward ends of the panels 10 12 14 and 16 from bulging outwardly and the clips 76 and 78 act to prevent forward and upward movement of the panel 20 particularly since the flange 84 and the corresponding flange of the clip 78 are below and supported by the flanges 24 and 24a the clips 68 and 70 are useful when the steps is to be formed in a corner of a building having two exterior walls extending at right angles to each other and in this case screws may be run through either the clips 68 into an adjacent wall of a building or through clips 70 into a wall of a building adjacent to the panels 14 and 16 the fluent concrete restrained by the forms 10 12 14 16 18 and 20 may be finished in accordance with conventional practice the uppermost step or platform may be preliminarily flattened and formed by drawing a straight edge along the uppemost flanges 28 and 28a and this surface may then be troweled smooth the intermediate step is formed by the front panel 18 and parts of the side panels 10 and 14 and this may also be roughly preliminarily formed and troweled smooth.
