Patent number: 8453413Abstract: A construction element of reinforced-concrete panel (1) in which is embedded a reinforcement framework includes at least one main framework layer extending along a tensioned outer face (11) of the element (1) and to which an inner framework (3) is attached for securing to the concrete, extending to the thickness of the element (1), the latter being produced, after the placement of the reinforcement framework, by pouring concrete onto a thin continuous wall (2) forming a sacrificial formwork. The thin wall (2) forming the sacrificial formwork extends along the tensioned face (11) of the element (1) and at the same time forms the main framework layer of the element (1), the nature and thickness of the thin wall (2) being determined so as to withstand the tensile stresses generated by the forces applied to the element (1) without the risk of separation from the concrete.Type: GrantFiled: July 5, 2007Date of Patent: June 4, 2013Assignee: Societe Civile de Brevets MatiereInventor: Marcel Matiere

Patent number: 8407959Abstract: A reinforced shrinkage compensating concrete slab has a major outer and inner faces defining a slab thickness and a centroid portion surrounded by a peripheral portion having outer peripheral edges defining a bulkhead length and width. A first plurality of reinforcing bars is embedded within the concrete slab on a plane which is substantially parallel to the major outer and inner faces. The first reinforcing bars extend in a first array having a first dimension defining a first on-centers-each-way orientation. A second plurality of reinforcing bars is embedded within the peripheral portion of the concrete slab in a second array which is a substantially intersecting and coplanar construction in relation to the first reinforcing bars. The second plurality of reinforcing bars are restricted to the peripheral portion and aligned with the expansive and shrinkage forces on a second dimension defining a second on-centers-each-way orientation so that the expansive and shrinkage forces are restrained.Type: GrantFiled: April 29, 2011Date of Patent: April 2, 2013Inventor: Donald G.

Patent number: 8381484Abstract: A building frame resistant to earthquakes, gale-force wind loads, fire, insects and rot includes a peripheral frame wall constructed of square or rectangular steel tubing. Side wall frame modules bolted together along adjacent edges, and end wall modules bolted together along adjacent edges and to the ends of the connected side wall modules form the peripheral frame wall. Diagonal bracing is built into selected side and end wall modules as required for the desired degree of wind resistance. Trusses made of various size tube such as 2Ć3 inch rectangular steel tubing for supporting a roof on the peripheral wall, are assembled and welded in a welding shop and the prefabricated trusses and wall modules are trucked to the building site. Multiple stones may be erected and fastened together, and the building frame is secured to a foundation or slab by attaching to anchor bolts or plates.Type: GrantFiled: February 15, 2008Date of Patent: February 26, 2013Assignee: ISSI Holding Company, LLCInventor: Delton J.

Patent number: 8381479Abstract: A pre-fabrication of a modular reinforcement cage for high-rise concrete construction is provided. The primary vertical bars, often referred to as the longitudinal bars, are held in formation by a set of templates that are manufactured to the design of the construction. These templates ensure accurate placement of the vertical bars and provides great rigidity for the module when being placed in the field. The main vertical bars can have thread-like deformations along the length of the bar, and are locked in place by use of compatible hardware against the templates. Multiple modules can then be stacked and coupled by use of mechanical couplings as construction continues.Type: GrantFiled: September 28, 2009Date of Patent: February 26, 2013Inventor: Felix E. Ferrer

Patent number: 8375676Abstract: Providing a half precast slab even in a case where the thickness of the slab in the site condition is too thick to apply conventional precast construction techniques. A half precast slab including a plurality of floor concrete form members and, each floor concrete form member being provided with: a bottom slab of a long length, in response to the floor concrete form member; a pair of side walls installed upright along each longitudinal edge of the bottom slab, in response to the floor concrete form member; thereby, each floor concrete form member is arranged so as to be parallel to each other and be tightly connected to the adjacent floor concrete form member, along the direction perpendicular to the longitudinal direction of each floor concrete form member; the height of the side walls other than the side walls on the most outer edge sides of the whole floor concrete form members is set at a common height that is smaller than the height of the side walls on the most outer edge sides.Type: GrantFiled: November 19, 2010Date of Patent: February 19, 2013Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Takeo Takakura, Satoru Tanaka, Yumi Tanaka, Toshiaki Kato, Naoyuki Kita, Nobuyuki Kawabata

Publication number: 20130031862Abstract: A floor formwork system is disclosed. The floor formwork system comprises a form member having a reinforcement beam attached to a surface of the form member. The reinforcement beam of the floor formwork system is positioned and attached in grooves within or on the contact surface of the form member. The reinforcement beam comprises a plurality of longitudinal rods or members, one or more of which are connected by a diagonal support member. Concrete is added to the assembled form member and reinforcement beam so as to create a floor or ceiling, or other structure. A method of assembling the formwork system and use for preparation for a floor or ceiling is also disclosed.Type: ApplicationFiled: April 19, 2012Publication date: February 7, 2013Inventors: Ronald Jean Degen, Fausto Bejarano Castillo, Humberto Trimino Vasquez, Pablo Rodriguez Acosta

Publication number: 20130008114Abstract: Method and device for strengthening and lightening floor and roof framing, where the beams and the compression slab are firmly integrated, making it possible to easily recover the moulds or blocks lightening the framing. The method uses several devices, prefabricated beams, moulds, mesh, concrete laid on site and where necessary reinforcing rods. The devices comprise essentially: a section, two bolts and a pin. The section will be tensile-stress resistant and folded into a āUā shape to match the beams. The method involves affixing the device, wrapped transversally around the beam. Likewise, and several devices can be affixed along each beam. The beams are then placed on their walls or girders, parallel and separated depending on the moulds, then the moulds are seated in the protruding segments of the bolts of the device until the spans are covered, affixing reinforcing rods in the sides of the device where necessary. The mesh is then laid by attaching it to the ends of the devices.Type: ApplicationFiled: November 16, 2010Publication date: January 10, 2013Inventor: Javier Antonio Simon-Dominguez
