Abstract: An apparatus for building stem wall forms which can be easily deployed by a form laborer to set up stem wall forms at a building site. The apparatus is collapsible for easy deployment and removal from a stem wall form. The preferred embodiment is comprised of a collapsible rectangular center structure coupled to a board holder and a board support arranged in diagonal relation to each other. The board holder allows the apparatus to hang from a first form board and the board support allows a second form board to rest thereon. In use, the apparatus functions by holding opposing form boards of a stem wall form in a parallel relation to each other, so that the form boards can be staked and nailed into place. Once the form boards are staked in place, to create a stem wall form, the apparatus can be collapsed, and removed from the form to be reused again at another location.

Abstract: A method and apparatus for forming a concrete foundation wall. A trench is opened in the ground and a form is inserted into the trench. The form is made up of a pair of spaced-apart opposing panels, which define a cavity. The panels may be made of a thermal insulating material, which may be extruded foam insulation or, more particularly, extruded polystyrene. The panels may be supported through a combination of J-channels, spreader brackets, connecting members, and a support member. The method further includes backfilling the trench around the form with dirt and pouring concrete into the cavity. The dirt provides support for the form as the concrete is poured.

A rib of the form panel is inserted between the wall and the body portion to secure the hanger to the form panel.

Abstract: The present invention is a method and apparatus for improving the connection between a building panel and a foundation. The improved connection is made possible by a unique form assembly that includes a trough assembly and a novel means for adequately supporting the trough assembly while the concrete is poured. The trough assembly creates a trough, which is an elongated hollow notch at the top of the foundation that resembles the shape of the trough assembly. Thus, the trough assembly is designed such that its width is approximately equal to the width of the building panel. The trough assembly also includes an angle iron affixed to the top of its sides. The trough assembly provides the building panel an elongated hollow groove having angle irons on each side. The prefabricated panel is therefor affixed to the angle irons. Placing the prefabricated panel in the foundation in such a manner and affixing it to the angle irons provides the panel with improved lateral and horizontal support.

Additionally, this forming tool can be made to be telescoping and adjustable between these standard widths, so that one tool could accommodate a variety of forming needs. Finally, this forming tool further comprises a leveling apparatus for allowing a precise horizontal and vertical level to be achieved across a foundation form.

Abstract: A finishing cap for concrete formwork is described herein for providing smooth finished concrete joints and corners while reducing the time, labor, expense, and expertise required to make such a joint. The finishing cap provides two non-parallel edges forming an angle, wherein the concrete formwork is fitted into the angle so provided. The angle between the edges of the finishing cap is provided so as to be somewhat smaller than the final desired angle of the finished concrete joint. A pinching action is created between the edges of the finishing cap and the formwork, and this pinching action prevents stones and concrete from entering the joint and roughing up the final finished joint. After the concrete is poured, smoothed and set, the finishing cap may be easily removed and a smooth finished corner is produced. The invention is described in relation to concrete formwork for stairs and walls.

Abstract: A simplified box-like building is constructed one room at a time. Concrete slabs are used for walls, floor and ceiling, and are poured in a horizontal position, stacked vertically with bond-breaking layers between them to allow separation. After the foundation and stub wall are partially cured, the ceiling slab is poured with wedge-shaped edges clearing stub walls by approximately one inch. Tiltable wall slabs are then poured on top of the ceiling slab, each connected by hinges to its own stub wall. An accelerated light weight low-slump concrete is normally used, and makes possible a rapid nearly continuous pouring sequence.Erection of the building is also rapid. The light weight walls are tilted up by hand, pivoting about their base hinges. While they are temporarily held in position, the wall edge dowel reinforcement is bent out and single-side corner forms are positioned or expanded metal is attached to the dowels.
