Abstract:
A method of erecting a building using pre-cast wall panels, which comprisesfirst erecting the wall panels and then casting a concrete column around the vertical edges of adjacent or intersecting wall panels using two or more movable formwork modules which together make up a set that can be assembled to form different configurations and sizes of column for different panel arrangements, each module having longitudinal edges and comprised of a central section and integral end sections that include a straight portion and a rearwardly extending flange located at the free end of each end section on the longitudinal edges, each flange extends perpendicularly to the straight portion so that adjacent modules can more readily be aligned and connected together; said set of modules including a first module for forming straight sections, a second module for forming a curved column section of a larger radius that comprises a patterned portion in said central section; and a third module for forming curved sections having a smaller radius than the larger radius of the second module; and a hollow infill module used for forming a corner where two other modules coincide at right angles, said infill module being of generally square cross-section, but with one corner rounded in a curve of the same radius as said smaller radius of said third module.
