Not illustrated. 1913 edition. Excerpt: ...for the pile caps and beams, or even for the floor slabs. Fig. 177 is a plan of a typical pile cap. For the purpose of constructing a concrete cap to a pile that has been driven a mould in the form of a box is made to surround Fig. 177.--Plan of Typical Pile Caps and Connecting Beams of the under.side of the slab, by which time it is probable that the moulds to the pile caps and beams may be struck, taken away, and cleaned for re-use. The filling in between the beams up to the level of the bottom of the floor slab should be completed by thoroughly punning and levelling off with some good, small, hard material such as a mixture of cinders and gravel, clinker, etc., so as to form a good bottom on which to lay the reinforcement for the floor slab (see Fig. 178). THE FOUNDATION SLABS The placing of the slab reinforcement is (see Fig. 179). By this means the bars will not get displaced. The notched templates can be removed shortly after the concreting has begun, quite a small quantity of concrete sufficing to hold the rods in place. However, before any concreting is done, the cross bars or distributing bars have to be laid and wired to the longitudinal bars at every (or, in most cases, every alternate) intersection. The work is not difficult or complicated, but it requires great care, and certain precautions need to be observed. For example, do not allow men to run indiscriminately over the steelwork after it has been laid down; instead, form runways with planks packed up from the ground so that they clear both the meshwork and the beams, it being borne in mind that, at this period of the work, the Fig. 180.-Raft Foundation Beam Reinforcement on Wooden Supports upper or compression reinforcement and the stirrups of the beams are projecting above the...show more
