circle. The foundation and slab area is now ready for reinforcement. See Chapter 6 forreinforcement of foundation. Follow the advice given there for the construction of the slab too. Makesure it will be level and smooth, otherwise there will be problems in assembling the mould. Beforeconcreting the slab, do not forget to place the water tap unit as shown in Fig. 5.8.5.2.5 Assembling the mould and placing the reinforcementfigure 5.31The mould is in six sections, each marked to ensure that they are assembled in the correct order.Tapered wooden spacers are used between the frames to make it easier to remove the sections(Fig. 5.28).Assemble the mould loosely near the base and check that all the pieces are present and fit properly.This should be done before the mould is required.Find the centre of the slab and mark a circle on the slab the same size as the mould to ensure themould is centred on the base.Take the first section A-B and place it on the line. Take the second section B-C, and place it on theline with the overlap outside the first section and the letters matching.Place the wooden spacers between the metal flanges and bolt them together loosely.Do not tighten until all sections are assembled.Bolt the remaining sections together in the correct order (B—C, C-D, etc.) until the mould is looselyassembled.Using the circle on the slab as a guide, move the sections until the mould is circular and in thecentre of the slab.Tighten all bolts.Place paper at the bottom of the mould to prevent oil from spilling on the concrete.
