39 In the construction of my improved wall I After the second wall isset and hardened I repreferably employ sheet metal mould forms of move the spreader bars. These are straight and the kind now in commlon use and which have uniform in size throughout and can easily be thus smooth sheet metal body portions l0 braced withdrawn. I find that in practice when these and reinforced by outwardly extended flanges spreader bars are removed before the removal of H, which flanges are plOVlded with holes I2 to the forms, their removal does not cause the con recelve pins 13, and I also employ spreader bars crete surrounding the spreader bars to ch1p ofi M to extend through openings formed in both to any appreciable extent. When the spreader of the forms and provided with two openings [5 bars are removed, the form sections are also reat one end through which the pins l3 may be exmoved, and after such removal the openings in ende the concrete wall from the outer side are filled 40 I'practice my improved method as follows: I with moistureproofing material l9, and I preferfirst erect the two forms in spaced apart position ably fill the openings at the inner side of the wall and, as is customary, each form structure is suitwith wooden plugs 20 which I have found to be ably braced and supported to hold it in position convenient for nailing wooden strips 2| to the Then in the space between the forms the first concrete wall so that a wooden wall 22 could be concrete wall is erected in the ordinary manner supported against the concrete wall when desired.

I have also found that with my improved double monolithic concrete wall the cracking of the walls due to expansion and contraction by temperature changes is almost wholly eliminated because, with the moistureproofing material in plastic condition one wall may be moved slightly in the manner in which it is moved by contraction or expansion without imparting a corresponding motion to the other wall, because the plastic moistureproofing page of one wall relative to the other.
I claim as my invention:
The method of constructing upright concrete material permits slipwalls, which consists in providing two upright mould forms, supporting said mould forms in spaced apart pos'tions by spacing bars extended through and beyond one of the mould forms, then filling the space between the mould forms and permitting it to set and harden and thereby firmly hold the spacing bars in position, then removing the mould form through which the spacing bars are extended, then applying a layer of compressible material to the exposed concrete surface, then replacing the mould form upon the spacing bars in spaced apart position from the compressible material and utilizing the previously formed concrete wall in firmly holding the spacing bars and supporting the replaced mould form, then fillingv the space between the compressible material and the replaced mould form with the concrete and removing the mould forms and spacing bars.
