A ventilation apparatus comprising:
- a plurality of tubular conduit sections, each conduit section including;
- a first semi-tubular section and a second semi-tubular section, each semi-tubular section having a cross-sectional profile generally in the form of an open semi-circular annular element, when viewed along a longitudinal axis;
- wherein each tubular conduit includes a first engagement formation located at an end of the tubular conduit, and a second engagement formation located at an opposing end of the tubular conduit;
- wherein the first engagement formation is defined by a flared female end portion;
- further wherein the flared female end portion is adapted to receive the second engagement portion defined by a male projection.
A method of installing a ventilation apparatus, the method including the following steps:
- securing a first semi-tubular section to a support structure,
- securing a second semi-tubular section to the first semi-tubular section to define a tubular conduit section, the tubular conduit section having a first engagement formation located at a first end, and a second engagement formation located at an opposing second end wherein the first engagement formation is defined by a flared female end portion, the flared female end portion is adapted to receive the second engagement portion defined by a male projection;
- and
- installing one or more additional tubular conduit sections such that the first engagement formation of each tubular conduit section engages with the second engagement formation of an adjacent tubular conduit section.
