#CONCRETE FORMS TO GO AROUND COLUMNS PDF#

The distance between the runners is less than the width of the panel. Supporting the concrete shaping means above the casting space for rectilinear movement, in the preferred embodiment, are a pair of rails projecting along the casting space over which ride a pair of runners that are secured to the shaping means. The shaping means is supported above the space in which the panel is to be cast for rectilinear movement. The thicker cross-section column will project upward from the surface of the panel prior to its being raised into its vertical position Since the column will be located about the center of a panel along its width rather than along one of its vertical edges, it is difficult to establish the shape of the column using fixed forms similar to those which generally surround the panel to establish its edges when it is initially poured.īriefly, the apparatus of the present invention includes concrete shaping means for receiving concrete and shaping it to form a reinforcing column along a wall panel. However, a difficulty with forming reinforcing columns in a panel prior to raising it occurs in shaping concrete to form the thicker cross-sectional shape for the column. The construction of such a tilt-up wall would be faster and, hence, less expensive were it possible to form columns for a panel prior to raising the panel into its vertical position. This method for constructing the structural reinforcing columns requires erecting the reinforcing material and the forms vertically prior to pouring the concrete, and then subsequently removing those forms after the concrete hardens.
