摘要： A building formwork component comprising first and second spaced sidewalls having one or more webs extending there-between, each sidewall comprising a flange extending inwardly along a first edge of the sidewall such that an outer surface of the flange forms a ramp surface; and a groove extending along an opposing second edge of the sidewall. The component may be coupled to a like component by relative movement of the components towards each other, whereby the flanges are received in respective grooves of the like component, and whereby the ramp surfaces facilitate such coupling by engaging respective second edges of the like component to move the second edges and/or ramp surfaces for engagement of the flanges in the grooves.

摘要： Disclosed is a form work system (100) that comprises first (102a) and second (102b) building formwork components that are connected by a building formwork connector (104). The connector (104) comprises a moveable portion (128) that is moveable from a closed position to an open position. In the closed position, one or more sidewalls of the connector (104) define a cavity (144) for receipt of cementitious material. The cavity (144) of the connector (104) is located with respect to cavities (110) of the first (102a) and second (102b) formwork components. In the open position, access is provided to the cavity (144) of the connector (104).
