Abstract:
A module for constructing foundations for a structure, comprising: a plurality of formwork members that define a pair of side walls that define a space between the side walls; thereto to hold the side walls in a spaced relationship; a three dimensional reinforcement cage that includes the brace, a plurality of first members, and a plurality of second members perpendicular to the first members, the first members coupled to at least the brace and the second members coupled to at least one of the plurality of the first members and the brace, wherein the cage forms an internal support within the space between the side walls for receiving a settable material, such that the side walls become integrated with the internal support as the settable substrate sets, to form the module.
Abstract:
A removable form tie system and methods of construction using same are disclosed. The removable form tie system may comprise first and second brackets for respectively mounting to a first and second forms spaced apart from one another. A wire runs from the first bracket to the second bracket. Each bracket preferably comprises a fastening wall and a channel adapted to receive one end of the wire. Each bracket may further comprise a holder for receiving the wire at a substantially orthogonal angle after being received by the channel. The holder may comprise a portion of a stiffening wall extending substantially orthogonally away from the fastening wall, as well as a detent extending substantially orthogonally away from the first stiffening wall. In the alternative, the holder may be an extension from the fastening wall, wherein the holder extends substantially orthogonally away from the first fastening wall and then bends back to be generally parallel to the first fastening wall. Where the forms are plywood, a bracket may include a stiffening wall extending generally orthogonal away from the fastening wall, wherein the stiffening wall includes a sleeve adapted to receive a pin. Methods of using the form tie system include using the brackets with sleeve and pin arrangement to secure one or more braces, such as walers or strong backs, to maintain rigidity of the forms. The disclosed inventions advantageously permit wet concrete to be poured between the forms and troweled with ease. The wire may be easily removed from the concrete, even days after the concrete has cured, for an aesthetically pleasing result without concern of wire oxidization issues.
Abstract:
Brackets for securing vertical strongbacks to horizontal walers secured to a face of a concrete wall form. Each bracket has a flange adapted to be mounted to an upper surface of the waler, a standoff connected to the flange and extending perpendicular to and beyond the waler to a distal end for defining a strongback-receiving pocket between the waler and the distal end for receiving the strongback. A wedge is operatively coupled to the distal end for pinching the strongback between the wedge and the waler for securing the strongback to the waler.
Abstract:
The invention comprises a product. The product comprises a foam insulating panel having a first primary surface and an opposite second primary surface. A removable concrete form is spaced from the foam insulating panel and a concrete receiving space is defined between the second primary surface of the foam insulating panel and the removable concrete form. A method of using a hybrid insulated concrete form is also disclosed.
Abstract:
This invention relates to a set of pieces or parts making up a system of metallic adjustable formwork for concrete structures in civil Works which functions is to allow the assembly, junction and adjustment of the formwork system in the most efficient way with the use of a system of adjustable formwork which looks for to use the shorter quantity of metallic panels as accessory during the project execution. The way as the each element has characteristics of specially defined shape, size and function to get a rigid structure, which allow to build a mold over which the concrete is poured maintaining their characteristics and perform such functions rapidly, efficiently and securely.
Abstract:
A system for forming architectural concrete walls comprises a plurality of modular form units (32), each form unit comprising a generally rectangular support frame, a backing sheet (34, 36) and an overlying facing sheet (56; 58), each facing sheet having a facing surface defined by a plastic material, an elastic seal (68) along an edge of the form unit for positioning between adjacent form units for preventing water leakage, a minimal number of tie holes (26) extending through each form unit, a seal tube (74) assembly for positioning between the tie holes, and a tie rod (80) for each tie hole. An architectural concrete wall having minimal tie holes and surface cavities and a highly polished marble-like surface is formed of a concrete mix including diatomaceous earth to impart a grey marble color and appearance.
Abstract:
A universal reusable system is provided for molding concrete or other settable fluids for use in building construction. In the subject system, apertured composite plastic panels and frames, prestressed by the presence of an array of removable and interchangeable oversized plastic plugs, are positioned and held in place by a framing system which utilizes a combination of apertured strips used as base guides and both vertical and horizontal channels, as well as dowels and plugs. The use of apertured panels and framing system provides for a reusable assembly whose dimensions can be readily set on site for each application and whose rectilinearity is maintained either by the dowel-aperture combination or by a combination of oversized plugs in adjacent members to be joined and connectors therebetween.
Abstract:
A modular wall form assembly includes two upright wall form panels, a bridging plate interposed removably between the wall form panels, and a plurality of coupling devices for connecting securely the wall form panels and the bridging plate. Each of the coupling devices includes at least three horizontally aligned coupling seats mounted respectively on the rear sides of the wall form panels and the bridging plate, and a T-shaped coupling lever. Each of the coupling seats is formed with a rectangular hole and a notch that is located on a longer side of the rectangular hole and that extends to the rectangular hole. The notch has a width shorter than the length of the longer side of the rectangular hole. The coupling lever has a handle that is transversely aligned with respect to a coupling portion. The coupling portion has a cross section that corresponds in size with the rectangular holes of the coupling seats. The wall form panels and the bridging plate are interconnected by inserting the coupling portion into the rectangular holes of the coupling seats.
Abstract:
A modular building system for constructing the frame of a structure. Standardized foundation forms, vertical forms, and tie beam forms are attached to each other. The vertical forms are hinged so as to be capable of defining a corner of any angle. Cover plates are selectively inserted into the tie beam forms so as to define a reception recess which corresponds to the size of a roof truss being used. The various forms can be attached to each other with a minimal amount of labor.
Abstract:
A formwork assembly for a poured concrete structure includes a plurality of formwork panels and girder-like members for supporting the panels. The panels comprise a concrete surface forming sheet and laterally spaced flange-like support members on the outside surface of the panel. The panel sheet is formed of an elastically deformable material so that the panel can follow the configuration of a curved surface of the concrete structure. The support members on the panels are notched or recessed at their ends so that the aligned support members on adjoining panels form a cutout to which the girder-like member is secured.
