This week work began in earnest to form the wooden shuttering into which he wall concrete will be poured.
The shuttering is a simple design to produce a reinforced concrete wall without the possibility of cold bridging, To insure it is straight and vertical, braced props are made from lengths of 4*2 timber.
Scaffold planks are then laid against the internal face of the uprights. Between the first and second planks and above the sixth plank resin rods a inserted through the wall.
Either side of these resin rods (steel ones would conduct heat through he wall). Large 6 inch timbers are placed either side of the rod and clamped in place with a steel plate and large resin nut.
Inside the wall the width of the wall is determined by small resin nuts set on the resin rod the correct distance apart.
Finally, planks are placed on the exterior surface of the wall and more strong boys bolted into place to provide rigidity for the whole structure.
Once all of the shuttering was in place scaffolders came to build a platform inside the shuttering which can be used when pouring and vibrating the concrete.
