Another effective and more generally applicable form of shuttering (designed and manufactured by the same firm) is illustrated in the diagram reproduced below. It should be observed that wedges intervene between the movable shutters and the uprights.
The method of employment of the “Mark V” shuttering is well illustrated by the bird’s-eye view showing the Newlands cottage under construction.
Alternative Shutterings
In this matter of shuttering there is still, however, great scope for improvement, and it may be hoped that soon ingenuity and experience will jointly produce a complete pisé plant perfectly fulfilling all the many conditions enumerated earlier in the book.
Shuttering made by riveting plain galvanised sheet iron to one side of a corrugated sheet has the qualities of lightness, smoothness, cheapness, and rigidity, and the claims of the inventor and patentee are now being put to the test in actual building.
PATENT SHUTTERING FOR PISÉ DE TERRE
By W. Alban Richards and Co.
There now seems little doubt but that pisé blocks will be largely used for partitions and chimney stacks where the soil is good enough, and experiments are being made with a view to discovering the best and cheapest way of making earth slabs similar to those of coke-breeze and concrete.
The size aimed at is 18 in. by 18 in. by 3 in., the edges to be tongued and grooved.
Certain “concrete” machines seem to lend themselves to adaptation for the making of earth blocks, but it is necessary to remember that sharp blows are required rather than a steady pressure, and also that we are working with a dry material. The ordinary primitive way of making pisé blocks is indicated below.
