Formwork system

A building formwork system comprising:

• first and second building formwork components, each comprising spaced sidewalls having spaced webs extending therebetween so as to define cavities within the first and second formwork components, the cavities being configured for receipt of a cementitious material, one of the spaced webs being located at a respective end of each of the first and second building formwork components;
• a connector connecting the first and second formwork components at the respective ends, the connector comprising one or more sidewalls having a detachable portion that is movable from a closed position to an open position;
• wherein:
• in the closed position, the one or more sidewalls define a cavity in the connector configured for receipt of the cementitious material, the cavity defined by the connector located at the respective ends of the first and second formwork components, with one of the one or more sidewalls being located to extend across a respective end proximate to a respective said one of the spaced webs;
• and
• in the open position, access is provided to the cavity defined by the connector;
• wherein said detachable portion includes a detachable element configured to provide said access to the cavity defined by the connector in the open position, the detachable element comprising two external sidewalls defining an external corner of the connector, and one or more internal sidewalls that extend therebetween, the internal sidewalls partially defining the cavity defined by the connector.
