Abstract: A square tubular steel frame extends between inner and outer concrete footing form walls and prevents the inner and outer form walls from bowing inwardly and causing an undesirable narrow footing width, or bowing outwardly and causing a form blowout. The steel frame is adjustable in width to accommodate the narrowest to the widest footings. A lower bracket supports the bottom of the form, and is adjustable in height. Each end of the frame is replaceable to accommodate a single form thickness, or to accommodate overlapping forms. The frame is reusable, easy to set up, and simple to take down and move to the next job, and is safe to use.

Abstract: Presented is an apparatus for stabilizing the form boards or members that define a cavity to receive wet concrete. The apparatus includes metal stakes having two sets of through-bores. The through-bores of one set are perpendicular to the through-bores of the other set and are spaced intermediately thereof. The stakes are driven into the ground in parallel pairs on opposite sides of the form boards. Nails are driven through one set of through-bores to attach the form boards to the stakes. A retention nail is slidably supported in a bore of the other set of bores so that it lies parallel to the form boards and above the top edges of the form boards. An elongated retention plate extends transversely above the form boards and opposite ends are detachably engaged to the nails that lie parallel to the form boards so as to prevent the form boards from displacing the stakes outwardly by the force exerted by the wet concrete.

Abstract: The present invention provides a system, for raising a manhole ring during construction or roads, that includes placing a generally tubular form on a manhole cone in an excavation, and a method and trimming/cutting tool for adjusting the height of the form. Preferably, the cutting tool is positioned inside the form and is rotated around to cut a ring of material off of the top of the form. The cutting tool is set at an elevation, indexed off of the pavement around the excavation, which results in the form being cut to a height that can support a manhole ring at a proper elevation to be flush with the pavement surface of a particular site. Once the manhole ring is placed on the trimmed form, a single pour of concrete may be done to create a concrete collar that fills and seals the vertical space between the manhole cone and ring. The form may include a stabilizing system for holding the form in place on the manhole cone.

Abstract: An adjustable concrete form comprises at least one tube and an adjustable stake having a post and a tube cradle. The tube has at least one drainage aperture providing the form with drainage. The adjustable stake is configured for adjustably supporting the tube in spaced-apart relation to an excavation bottom. The post has at least one slender end to facilitate driving the post partially into the excavation bottom. The tube cradle is configured for releasable engagement with the tube to thereby secure the tube relative to the post and to support the tube in spaced-apart relation to the excavation bottom. The tube cradle is adjustably connected to the post so that adjustment of the post relative to the cradle effectuates adjustment of the tube relative to the excavation bottom.

Abstract: A footing/foundation form with an integral drain having two substantially parallel spaced apart, serpentuitous walls. Each wall includes a plurality of hollow tubes elevated "to grade" above an excavation bottom by a stake and clip mechanism with gravel filled between the elevated tubes and the excavation bottom such that the elevated tube and gravel both engage concrete poured between the walls. The tubes are common 10-foot PVC tubes with a plurality of holes positioned away from the footing/foundation thereby providing the form with an integral drain. The stakes are preferably pieces of reinforcing bar and the clips, while quite effective, are also inexpensively manufactured.

Abstract: A bracing system for a concrete form includes at least one spacer holding and spanning opposing sides of the form, and at least one inclined strut. The strut, at its upper end, attaches to the spacer and, at its lower end, engages the ground. The strut lower end has a spike and a foot plate for driving the spike into the ground by the user's weight. Preferably, two struts are employed, one on either side of the form. Both attach to the same spacer by dowel sockets and dowel pins. Each strut prevents the form from collapsing on its respective side. Each strut is independently adjustable as to length due to telescoping members having aligned holes, and is locked at a desired length by a spring loaded, captively retained pin. The bracing system is quickly and easily assembled by hand, and is retained in place by pins secured by clips.

Abstract: Adjustable forms for pouring precast concrete slabs and similar articles of manufacture. The forms may be used either on site to produce concrete slabs as needed, or at a central manufacturing location, for transport to the site where needed. Concrete slabs produced with the adjustable forms may be used in patios, sidewalks, storage room or pump house floors, driveways, mobile home landings, and the like. The slabs may be steel reinforced, with expandable interlocking design, of various sizes, patterns and colors. Similar construction materials or decorative articles, such as tile, wallboard, and the like may also be produced with the improved forms.

Abstract: A concrete forming system for the casting of floating slab building foundations with perimeter insulation. Form panels (14A), (14B), (14C), and (14D) comprised of foam core (54) and metal rails (42) and (44), and overlain with stress skins (50), are connected by form tie assemblies (18A), (18B), (18C), and (18D). A protective shield (40) covers the exposed portions of panels (14A) and (14D). Metal stakes (16) anchor formwork assemblies to the earth. System includes embedded anchors (64) and (38). Panel connectors (30) and (32) allow formwork assemblies to be pre-assembled into long lengths, which provides straight and level slab edges and great labor savings. Forming system provides lightweight forming panels, stakes, and lateral bracing which remain in place, providing perimeter insulation and finish exterior surfaces.

Abstract: A device for establishing the correct spacing (width and height) between a pair of sheet material elongated form members between which a slurry of concrete is to be poured and, when solidifed, will produce a rigid concrete curb. One form member is to be held in place within a first rigid member with the remaining form member to be held in place by a second rigid member. The first and second rigid members are connected together thereby establishing the width of the resultingly formed curb. Each rigid member includes a pin which is to connect with the inside surface of its respective form member. Once the slurry has been poured between the form members, these pins are to be removed prior to the slurry solidifying. Once the slurry is solidified, the curb form device is to be completely disconnected from the form members with the form members also being separated from the resultingly formed concrete curb.

Abstract: A tool for installing an object for example a flammable fluids containment box in a form for a concrete structure has an elongated bar oriented horizontally, and four slidable assemblies mounted on it. Two outer assemblies each have a horizontal rod section around the bar and a T-screw or allen head bolt for fastening the rod section in place on the bar. The outer assemblies have a mechanism to engage a lip of the form, and a mechanism to support the assembly on the ground outside the form if the form is lipless. The inner assemblies each have a horizontal rod section that fastens in place on the horizontal rod, and has a vertical rod attached to its underside. At the bottom of the vertical rod is an assembly for fastening the containment box such that the tool thus suspends the containment box in position in the form, so that the box will set in place in the concrete.
