Abstract
The present specification discloses an apparatus
and method for producing concrete beams for use in the
construction industry. Concrete beams are
conventionally made in suitable moulds in a factory,
the beams being removed from the mould and transferred
to the construction site. However, removal from the
mould and transit can cause the beams to be damaged,
besides adding to the production cost.
The present invention provides an apparatus which
is manhandlable without the need for lifting gear, and
which can be used on site, thereby reducing production
cost and the possibility of damage. The apparatus
comprises a number of vertical supports (5) between
which horizontal support members (7) extend. Elongate
mould members (17) rest generally horizontally on the
support members (7), abutting one another so as to
define a number of adjacent, parallel, generally
U-shaped channels (19). In use, concrete is poured
into the channels (19) and after hardening the mould
members (17) are separated, it being a relatively
easy operation to release the L-shaped mould members
(17) from the beams with little, if any, damage.
