摘要 |
<p>The mould is designed to produce a set of eight concrete pillars or rods at the same time. The mould (1) has a rectangular external profile and contains two rows each four holes of irregular octagonal shape (2-9). The holes are separated by partition walls so that they do not permit the fluid concrete to form a link. Each row of holes is arranged with the largest hole at one end and the smallest at the other, the opposite row having the holes in reverse order. Each octagonal hole has a pair of sides (10) parallel with the long side of the mould and another pair of sides (11) parallel with the short side of the mould.</p> |
