Abstract
Abstract A method of erecting wall forms of the type used to cast concrete walls in which a pair of form panels are first positioned in spaced, wall-defining relation to one another, tie rod assemblies are inserted transversely through the panels and attached thereto to hold the panels in spaced relation, external stud and waller bracing is subsequently erected on the outer sides of the panels, and the tie rod assemblies are then connected in force-transmitting relation to the bracing.

A method of erecting a wall-form panel assembly of the type having a pair of form panels, external bracing for said panels, tie rod assemblies extending transversely across said panels and interconnecting said bracing, and a pair of tubular cone members associated with each tie rod assembly, adapted to be secured to said panels and extend therethrough, said tie rod assemblies being slidably received in said cone members, comprising the steps of: a. positioning said panels in spaced parallel relation to one another to define opposite faces of a wall; b. securing said tubular cone members to said panels; c. inserting said tie rod assemblies through said panels and said tubular cone members; d. fixedly securing said tie rod assemblies to said cone members to prevent relative movement of said panels and said tie rod assemblies; e. erecting said external bracing on said panels; and f. subsequently securing the ends of said tie rod assemblies to said bracing in force transmitting relation thereto.
