Patent number: 6792734Abstract: A device for protecting lifting inserts having a tubular body during embedding in a concrete component, comprising an elastically deformable element insertable in the axial end of the tubular body of the lifting insert directed toward the outside of the prefabricated component engageable for lifting the prefabricated component. The elastically deformable element occupies an axial portion of the tubular body starting from axial end. The device comprises expansion elements, which act on the elastically deformable element to cause a radial expansion thereof through the elastically deformable element engaging whereby the inside walls of the tubular body to prevent infiltration of concrete through the axial end of the tubular body of the lifting insert.Type: GrantFiled: December 17, 2001Date of Patent: September 21, 2004Inventors: Sergio Zambelli, Benito Zambelli

Patent number: 6705053Abstract: An apparatus and a method are provided for lifting and leveling an existing building from a position underneath the existing building. At least a first non-cylindrical support section having a substantially rectangular shape and first and second ends is located within the earth at a position underneath the existing building. A cap support section is placed in contact with the second end of the first non-cylindrical support section. A jack is disposed on the upper side of the cap support section and raised until the foundation of the existing building has been lifted to a desired height. The non-cylindrical support section has low bearing and high friction characteristics. The low bearing characteristics enable the apparatus to be driven further into the earth than cylindrical pilings that are commonly used to lift and level existing buildings. The high friction characteristics assist in maintaining the stability of the apparatus once it has been installed.Type: GrantFiled: March 6, 2001Date of Patent: March 16, 2004Inventor: Mark Dimitrijevic

Patent number: 6658799Abstract: A volumetric modular building system comprising a reinforced concrete inverted “tee-beam” module. The module has a series of integral cross-walls which are spaced to coincide with the dimensions of the rooms and corridors constituting a section of a building, these rooms being formed by a matched pair of such modules acting in parallel, separated by, and adapted to support between them, a suspended concrete floor, external infill walls, internal partition walls, fixtures and services. The dimensional control of the modules is ensured by means of a removable structural steel framework gauge attached to and forming a part of the casting mold adjacent to the ends of the integral cross-walls. The legs of the gauge serve to locate and secure, during casting, top and bottom steel bearing-plates which are in turn separated, regulated and perforated by vertical steel tube tie-rod sleeves embedded locally near the ends of the concrete cross-walls.Type: GrantFiled: April 19, 2001Date of Patent: December 9, 2003Inventor: William Richard Charles Stoodley

Patent number: 6581996Abstract: A lifting system for hoisting heavy pre-cast panels includes an anchor-lifting device permanently secured within a connection recess formed in the panel, and a connecting apparatus that attaches to the anchor-lifting device. The anchor-lifting device presents a laterally disposed connection pin for attachment to a pair of laterally spaced lifting hooks that form the connecting apparatus.Type: GrantFiled: April 26, 2000Date of Patent: June 24, 2003Inventor: Lawrence Fromelius

Publication number: 20030074846Abstract: A method and apparatus for installing backing in walls which include a first, second and third upright U-shaped stud. A first backing member has a first end, a second end, a top, a bottom, a first side and a second side. The first backing member is disposed between the first and second studs. A second backing member has a first end, a second end, a top, a bottom, a first side and a second side. The second backing member is disposed between said second and third studs. A hinge is operatively attached to the first side of the first and second backing members for permitting the second backing member to pivot with respect the first backing member between a first position wherein the first side of each of the first and second backing members are substantially in the same plane and a second position whereby the first and second backing members are not in the same plane. This permits the first backing member to be placed between a first and second adjacent vertical stud.Type: ApplicationFiled: October 19, 2001Publication date: April 24, 2003Inventor: Daniel W. Tollenaar

Publication number: 20020062603Abstract: A brace for use in tilt-up construction is disclosed. The brace includes a bottom surface and a vertical side surface. The bottom surface of the brace is affixed to a permanent horizontal surface (e.g., a slab) in a manner that allows the brace to be removed without damaging the permanent horizontal surface. The vertical side surface of the brace is attached to a concrete pour form. The bottom surface of the brace is affixed to the permanent horizontal surface using an adhesive. Alternatively, a shoe is attached to the permanent horizontal surface and the brace sits in the shoe.Type: ApplicationFiled: November 29, 2000Publication date: May 30, 2002Inventors: Scott Shaw, Dale R. Haslem, Ken Lee, Steve Wilbur

Patent number: 6390734Abstract: A device and method are provided for leveling and supporting a slab foundation on a column of piling sections. A vertical hole is bored through the slab foundation and an anchoring cylinder is inserted in the hole. An adhesive is used to adhere the outer surface of the anchoring cylinder to a portion of the foundation. The cylinder has a plurality of downward-facing load shoulders which are engaged by upward-facing shoulders of a reacting member positioned across and above the hole. Piling sections are inserted into the anchoring cylinder and forced into the earth with a driving device that reacts against the reacting member. The anchoring cylinder is then supported on the piling sections to maintain the desired level of the foundation.Type: GrantFiled: January 4, 2001Date of Patent: May 21, 2002Inventor: Frederick S. Marshall

Patent number: 6260311Abstract: A concrete form suspension system has a form support projecting laterally from an upper portion of a vertically displaceable support structure and a hydraulic jack operable to raise the support structure along a vertically extending concrete structure. A support device can be secured to the concrete structure for supporting the jack and support brackets can be secured to the concrete structure for supporting the raised support structure from the concrete structure. By operation of the jack, the support structure can climb the concrete structure to allow concrete forms suspended from the form support to be located in position for use in upwardly extending the concrete structure.Type: GrantFiled: February 11, 1999Date of Patent: July 17, 2001Inventor: Peter Vladikovic
