Abstract
This disclosure relates to a formwork element and a formwork assembly, that can be used to mould upwardly extending building features such as columns or walls that extend between adjacent floor slabs. In one form, the formwork assembly comprises at least two surface forming elements, wherein each surface forming element comprises a casting surface and a pair of lengthwise extending parallel edges. In use, the surface forming elements are stacked by abutting along these edges, and each of these edges comprises a means for interlocking the surface forming elements with respect to each other so that the resulting formwork assembly forms a single, continuous casting surface.
Claims16
A formwork assembly for moulding an upwardly extending building feature, the formwork assembly comprising at least two surface forming elements for forming one side of said building feature, each surface forming element comprising a rectilinear perimeter frame and an infill panel, and a continuous casting surface, said frame comprising at least a pair of lengthwise extending parallel side members, and a pair of parallel end members, each of the pair of lengthwise extending parallel side members comprising a means for interlocking the surface forming elements with respect to each other, said means comprising a profile shape which is substantially constant throughout a length of the lengthwise extending parallel edges, and which comprises at least one projection and at least one recess which is an inversion of the projection, and wherein, in use, the surface forming elements are stacked by abutting along the lengthwise extending parallel edges so that interlock is effected engagement of the projection of one element with the recess of the other, and vice versa, such that the resulting formwork assembly forms a single, continuous casting surface, and wherein the lengthwise extending parallel side members of the frame further comprise a plurality of apertures spaced apart there along, for receiving threaded fasteners, pins or the like to secure the stacked surface forming elements with respect to each other.
A surface forming element for a formwork assembly for moulding an upwardly extending building feature, the surface forming element comprising at least two surface forming elements, each surface forming element comprising a rectilinear perimeter frame, an infill panel, and a continuous casting surface, said frame comprising at least a pair of lengthwise extending parallel side members, and a pair of parallel end members, each of the pair of lengthwise extending parallel side members comprising a means for interlocking the surface, forming elements with respect to another surface forming element, said means comprising a profile shape which is substantially constant throughout the length of the lengthwise extending parallel edges, and which comprises at least one projection and at least one recess which is an inversion of the projection, and wherein, in use, two or more surface forming elements are stacked by abutting along these edges so that interlock is effected by engagement of the projection of one element with the recess of the other such that the resulting formwork assembly forms a single, continuous casting surface, and wherein the lengthwise extending parallel side members of the frame further comprise a plurality of apertures spaced apart there along, for receiving threaded fasteners, pins or the like to secure the surface forming element with respect to another surface forming element.
