Abstract
Reinforced concrete building products are manufactured using a two-part mould (2, 3), the two parts being hinged together about an axis (4) which is adjacent an edge of each part-mould (2, 3). Glass-reinforced concrete is applied to each part-mould (2, 3), then allowed to partly dry before the part-moulds (2, 3) are folded together to produce a finished product.
Claims2
A mould for manufacturing a glass reinforced concrete building product, comprising:
- a first part and a second part, each of the first and second parts having a moulding surface, the first and second parts being hinged together about a hinge between an open orientation and a closed orientation in which a mould cavity having an internal surface is defined between the first and second parts;
- wherein the hinge forms part of the first part moulding surface and the second part moulding surface and the internal surface of the mould cavity;
- and
- such that a layer of glass reinforced concrete being applied continuously across the first part moulding surface and the second part moulding surface before the first and second parts are folded together from the open orientation into the closed orientation forms a continuous glass reinforced concrete building product.
