Abstract
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; wherein 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.
Claims18
A building formwork component configured to provide a mould into which cementitious material is to be poured, the building formwork component comprising first and second spaced sidewalls having two or more webs extending therebetween, each sidewall comprising:
- a flange extending inwardly along a first edge of the sidewall such that an outer surface of the flange forms an acute angle with the sidewall so as to define a ramp surface, the first edge having a longitudinal extent;
- and
- a groove extending along an opposing second edge of the sidewall, the groove disposed in a portion of the sidewall that extends from an end web of the two or more webs to a free end at the second edge, the second edge having a longitudinal extent;
- wherein a first web of the two or more webs extends between the sidewalls in proximity to one of the flange and the groove of the first sidewall and in proximity to one of the flange and the groove of the second sidewall, the first web being spaced inwardly from the one of the flange and the groove of the first sidewall and from the one of the flange and the groove of the second sidewall in a first direction toward an other of the flange and the groove of the first sidewall and toward an other of the flange and the groove of the second sidewall,
- wherein a second web of the two or more webs extends between the sidewalls at a location spaced from the first web in the first direction, the second web being spaced inwardly from the other of the flange and the groove of the first sidewall and from the other of the flange and the groove of the second sidewall in a second direction opposite the first direction,
- wherein the component is configured to be coupled to a like component by relative and generally lateral movement of the components towards each other, the lateral movement being transverse to the longitudinal extent of the first and second edges, 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 snap engagement of the flanges in the grooves;
- and
- wherein the sidewalls are sufficiently flexible adjacent at least one of the flange and the groove to allow one of the sidewalls to flex as the second edge of the like component moves along the ramp surface until the flange snaps into the groove.
A building formwork component configured to provide a mould into which cementitious material is to be poured, the building formwork component comprising first and second spaced sidewalls having two or more webs extending therebetween, each sidewall comprising:
- a flange extending inwardly along a first edge of the sidewall such that an outer surface of the flange forms an acute angle with the sidewall so as to define a ramp surface, the first edge having a longitudinal extent, the flange spaced along the sidewall a first distance from the one of the two or more webs nearest to the flange;
- and
- a groove extending along an opposing second edge of the sidewall, the groove disposed in a portion of the sidewall that extends from a web nearest to the groove to a free end at the second edge, the second edge having a longitudinal extent, and the groove spaced along the sidewall a second distance from the one of the two or more webs nearest the groove;
- wherein the second distance is greater than the first distance such that the groove and the second edge are configured to move laterally to a greater extent than the flange and the first edge;
- wherein a first web of the two or more webs extends between the sidewalls in proximity to one of the flange and the groove of the first sidewall and in proximity to one of the flange and the groove of the second sidewall, the first web being spaced inwardly from the one of the flange and the groove of the first sidewall and from the one of the flange and the groove of the second sidewall in a first direction toward an other of the flange and the groove of the first sidewall and toward an other of the flange and the groove of the second sidewall;
- wherein a second web of the two or more webs extends between the sidewalls at a location spaced from the first web in the first direction, the second web being spaced inwardly from the other of the flange and the groove of the first sidewall and from the other of the flange and the groove of the second sidewall in a second direction opposite the first direction;
- wherein the component is configured to be coupled to a like component by relative and generally lateral movement of the components towards each other, the lateral movement being transverse to the longitudinal extent of the first and second edges, 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 ramp surfaces laterally for snap engagement of the flanges in the grooves;
- wherein the sidewalls are sufficiently flexible adjacent at least one of the flange and the groove to allow one of the sidewalls to flex as the second edge of the like component moves along the ramp surface until the flange snaps into the groove;
- and
- wherein the two or more webs are arranged such that, when the component is coupled to the like component, the web of the component nearest to the like component is sufficiently spaced from the web of the like component nearest to the component so as to define therebetween a recess configured to receive cementitious material.
