Publication number: 20100101179Abstract: A structural reinforcement system that is implemented during the preparation of the area when pouring a concrete slab such as, but not limited to, commercial and residential floors, patios and driveways. The system includes digging foundation holes that are selectively disposed around the area being poured. The system further includes positioning steel bars above the ground in the lower twenty-five percent (25%), rather than upper fifty percent (50%) as known in the prior art, of the concrete being poured.

Patent number: 7069703Abstract: A method and system are provided for constructing large, continuous, concrete slabs without using conventional shrinkage joints. The system comprises a grid of closely-spaced crack inducers (2) arranged relative to a concrete-pouring surface and adapted to be covered by concrete. The crack inducers (2) may be connected to one another with connectors (10). The crack inducers (2) are of a size, shape and spacing to promote formation of fine cracks in the vicinity of the inducers (2) throughout the slab when the concrete sets.Type: GrantFiled: February 4, 2003Date of Patent: July 4, 2006Assignee: Building Innovations Pty LtdInventors: Warwick Ian Colefax, Robert Foster Colefax, Miro Getaldic

Patent number: 6532714Abstract: A method for restoring load transfer capability across a joint between two adjacent concrete slabs includes cutting a perpendicular to the joint and extending into each of the adjoining slabs. A generally flat joint tie is positioned in the slot before filling the slot with polymer concrete. The joint tie may have holes extending between the broad faces of the joint tie, with rounded corners, and made of fiberglass.Type: GrantFiled: March 16, 2000Date of Patent: March 18, 2003Inventors: Carl A.

Publication number: 20030041555Abstract: A method for constructing modular high-rise buildings is described. Precast modules forming a portion of a level of the building are formed at ground level, and are lifted in position on the level being assembled. Most of the finishing and testing work for the precast modules is carried out at ground level, resulting in a safer and less expensive construction. Once in place on the building's level, the precast modules are secured with concrete pours and other strengthening devices.Type: ApplicationFiled: May 21, 2001Publication date: March 6, 2003Inventors: L.

Patent number: 6513300Abstract: A wall cladding anchorage has a rod with ends loosely enveloped by fabric sleeves. The wall is drilled to receive one end and the cladding is drilled, or otherwise formed with a cavity, to receive the other end. Either the wall or the cladding may have the anchorage fixed first, by grout being injected to expand the sleeve and seep through it to bond to the drilling or cavity wall. Then the cladding is offered up and the other sleeve likewise expanded, the grout being injected via a duct leading between the cladding and the wall. Instead of a single part rod, there may be two elements, such as a tube and a rod that screws into it, each with a sleeve so that the cladding or wall need not have significantly projections until shortly before the cladding is fixed. It is also possible to have a single sleeve over the whole rod and inject grout into its central zone, between the wall and cladding.Type: GrantFiled: July 24, 2000Date of Patent: February 4, 2003Assignee: International Intec TradingInventor: Peter James

Patent number: 6430889Abstract: A finish mounted framed building element such as a window or doorway sidelight or the like is mounted in a space provided in rough framing structures in a wall, by inserting facing sheets, preferably of sheet metal, into the framing jambs up to a variable depth in slots provided at the perimeters of the door or window frame opening. The space between the sheets can be substantially confined as a foaming composition is injected and permitted to expand and cure in place. The foam locks the sheets to the framing jambs of the window or doorway sidelight, etc. This provides a wall panel with a correctly sized and correctly positioned internal opening, for example to receive a window frame or doorway sidelight or other insert structure. The invention also supports or reinforces the window or doorway generally, for example to support the hinged side of a door jamb adjacent to a door sidelight.Type: GrantFiled: April 27, 2001Date of Patent: August 13, 2002Assignee: Signature Door Co. Inc.Inventor: Dennis Eugene Nixon, Sr.

Publication number: 20020050113Abstract: An attachment system for use with a concrete form for securing an object within concrete as it cures is described. The attachment system comprises a sacrificial securing element and a tie rod with a first end and a second end. The first end removably engages the sacrificial securing element. Together, the tie rod and the sacrificial securing element jointly secure the object to the inside face of the concrete form. Moreover, the attachment system secures an object by using a single form and can be used when adding siding or exterior designs. In another aspect, a method of securing an object within a concrete wall using a concrete form is described. The method includes the steps of positioning the object in contact with an inner face of the concrete form and positioning a sacrificial securing element proximate the object and amidst a channel. The method also includes pouring cement within the channel and curing the cement to form the concrete wall.Type: ApplicationFiled: May 23, 2001Publication date: May 2, 2002Inventor: Donald Greg Peacock

Patent number: 6298631Abstract: A method for attaching a window well to the outer surface of a window opening. The method includes providing a window well mold, and providing a window well clip for use with the mold, the clip having a first face and a second intersecting face. An opening is provided in the first face for receiving a bolt, with a sheath aligned with the opening. A support member is provided extending between the two faces to provide rigidity for the well clip. Means are provided for removably attaching the clip to the window mold, and the clip is attached to the mold to form a mold-clip assembly. The assembly is next set in fresh concrete with the first face flush with the outer surface of the window opening. After the concrete is hardened, the mold is removed, leaving the clip embedded in the concrete. A bolt is then provided and inserted into the first face opening, attaching the bolt to the window well, and tightening the bolt into the sheath.Type: GrantFiled: July 19, 1999Date of Patent: October 9, 2001Inventor: Todd Finley
