Patent number: 5538361Abstract: A system for forming a single-walled trench comprising a pair of frame members, each having a horizontal section and a section depending from the horizontal section; a collapsing pair of wall pans having sidewalls interior to the depending portion of the frame members, a bottom floor disposed between the sidewalls, a releasing mechanism to collapse inward the sidewalls, a device which collapses the sidewalls inward and removes the entire bottom and sidewalls from the poured trench leaving the frames embedded securely in the concrete; and adjustable anchoring means attached to the frame members for providing vertical adjustment of the frame members relative to the ground and each other, leaving all but the frame members available for re-use.Type: GrantFiled: July 22, 1994Date of Patent: July 23, 1996Assignee: Hoosier Group, L.L.C.Inventor: John V. Beamer

Patent number: 5478169Abstract: A trench forming assembly and removable form for forming a trench of predetermined shape is disclosed according to the present invention. The removable form includes an elongate form body having top, bottom and opposed side surfaces and first and second elongate form removal slots extending upwardly from the bottom surface of the form body. Preferably the removable form has a top surface defining a complex shape including at least a first upwardly extending ear portion which extends longitudinally along the top surface. At least a first form removal slot of this elongate form body extends into a portion of the first ear portion. Advantageously, the form body includes a pair of coplanar elongate slots integrally formed in the side surfaces for receiving a pair of frame members in a predetermined coplanar, spaced relationship above the bottom surface of the form body.Type: GrantFiled: September 13, 1993Date of Patent: December 26, 1995Inventor: Lannie L. Stegall

Patent number: 5413307Abstract: A mold for casting an inverted base section of a manhole includes a core for forming an inner surface of the base section, and a jacket surrounding the core for forming an outer surface of the base section. A domed plate atop the core but below an upper edge of the jacket, and having a peripheral shape corresponding to that of the core, seals off the interior of the core and produces the floor shape of the base section. A trough former is placed between opposite interior sides of the jacket and above the domed plate. The flanges of the trough former are cut along arcs conforming to the shape of the domed plate so that cementitious material poured into the mold does not leak between the domed plate and the trough former. Hole formers are similarly seated atop the trough former.Type: GrantFiled: November 22, 1993Date of Patent: May 9, 1995Assignee: The Concrete CompanyInventor: Joe Tidwell

Patent number: 5301918Abstract: A system for constructing concrete culverts is disclosed wherein reusable outer form and rebar supporting assemblies are set in place in an excavation and are used to form outer portions of the floor and outer walls of the culvert. Forming the outer walls of the culvert is facilitated by anchoring the lower regions of the form assemblies in the outer region of the floor as it is being poured by means of concrete anchors, which remain set in the concrete but are removable from the form assemblies. As a particular feature of this invention, the form assemblies are each provided with a protective wall spaced from the form assembly and adjacent walls of the excavation, forming a protective space where workers may work while being protected from collapse of walls of the excavation.Type: GrantFiled: January 6, 1992Date of Patent: April 12, 1994Inventor: C. B. Miller

Patent number: 5281052Abstract: A system for forming a multi-walled trench comprising an outer wall, an inner wall disposed within the outer wall and along which the fluid to be contained flows, means for securing in position the inner wall so as to allow expansion and contraction thereof relative to the outer wall and means for vertically adjusting the trench relative to the surface elevation prior to the pouring of concrete. Various embodiments of the securing means are provided.Type: GrantFiled: May 7, 1993Date of Patent: January 25, 1994Assignee: Construction Casting CompanyInventor: John V. Beamer

Patent number: 5198246Abstract: A concrete molding device is provided for settling poured concrete. In a preferred embodiment, the form is composed of a plurality of segments stacked one upon the other, each having at least one strengthening flange located on its inner periphery. A vibratory unit containing a base unit provided with a slot is then attached to a flange in tongue and groove fashion.Type: GrantFiled: September 27, 1990Date of Patent: March 30, 1993Assignee: Monoform, Inc.Inventor: Kenneth T. Bowen

Patent number: 5125617Abstract: Forms for a cylindrical wall of poured concrete are made of plywood sheets nailed to horizontally-spaced beams, to which are clamped transversely arranged walers. The walers are assembled in strings and the string are in parallel spaced relationship. The walers in a string are hinged together at the sheet-facing side of the walers and at least one of two adjacent waler sections is curved. Screw assemblies are mounted in brackets located at the ends of the walers but on the sides facing away from the sheets, and are operable to push or pull the walers out of alignment so that they can be pulled or pushed into a ring shape and, in so doing, bend the sheets into generally cylindrical shapes. When the sheets are raised on end, with the beams disposed vertically they provide the inside and outside wall forms for receiving concrete, for example, poured between them to form an annular cylindrical wall for a tank or the like.Type: GrantFiled: September 3, 1991Date of Patent: June 30, 1992Inventor: Alan P. Miller

Patent number: 5108671Abstract: A formwork for a draft tube which includes ganged precast forms, each precast form corresponding to a curved segment of the draft tube. The precast forms are molded with continuous side plates extending thereabout and anchored in the precast concrete form and projecting beyond the surface opposite to the contact surface to provide a flange. A fastening means for attaching adjacent forms with a space therebetween to allow for stripping. A method includes determining the outline of the inner surface of the draft tube and dividing it into segments and preparing molds to make precast forms corresponding to each segment. The precast forms are assembled and shored to provide the draft tube ganged formwork, and concrete is poured about the draft tube formwork and is cured. The precast forms are stripped from the set concrete structure and reused in another draft tube formwork.Type: GrantFiled: August 7, 1991Date of Patent: April 28, 1992Assignee: Kiewit Construction Group Inc.Inventor: Louis Chapdelaine

Patent number: 5017313Abstract: A form assembly for casting a lining wall in an existing manhole includes a cylindrical lower form assembly, a circular horizontal form assembly, and a cylindrical upper form assembly. All three assemblies are formed of smaller segments which are assembled together within the manhole and which can be disassembled after the manhole has been repaired.Type: GrantFiled: September 27, 1990Date of Patent: May 21, 1991Assignee: Action Products Marketing CorporationInventor: Carroll O.
