A method of forming concrete integral box shaped modules provides dimensional accuracy and sustains closer tolerances thus permitting surfaces of adjacent modules to match. The method utilizes a standard fixed box frame with vertical walls that can be easily reset after forming a module. The method includes the steps of constructing a fixed box form with four vertical rectangular sides and a top horizontal surface, top trays extending out from top edges of the rectangular sides and bottom trays extending out from bottom edges. Corner fillers are placed in vertical corner spaces formed by the four vertical sides, steel mesh and rebar is laid on the vertical sides and in the trays, the trays are then filled with concrete and concrete is sprayed onto the vertical sides. The module is steamed to set the concrete, the trays are removed and the module is raised initially by jacking to release the module from the box form.

[ I claim:] [1.] A method of forming a concrete integral box shaped module having four rectangular side walls surrounding a rectangular end wall, comprising the steps of:constructing a fixed box form, having four vertical rectangular sides and a top horizontal surface with vertical corner spaces at each corner between adjacent vertical sides;positioning top trays extending out from top edges of the four rectangular sides, and bottom trays from bottom edges of the four rectangular sides;placing corner fillers at the vertical corner spaces to stabilize the vertical sides and block the corner spaces;laying reinforcing steel mesh and rebar on the top horizontal surface, the top trays, the bottom trays and against the four vertical sides;filling the bottom trays with concrete to form lower lips extending out from bottom edges of the side walls of the module;spraying concrete on the reinforcing steel mesh and rebar on the four vertical sides to form the side walls of the module;filling the horizontal surface of the box form and the top trays with concrete to form the end wall, with upper lips extending out from top edges of the side walls of the module;steaming the module on the box form to set the concrete;removing the top trays from the module, andremoving the module from the form by lifting and at the same time jacking up the lower lips of the module to separate from the bottom trays with the corner fillers permitting relative movement of the vertical sides of the form to assist in removal of the module from the form.
