A product and a method of manufacture and assembly of a prefabricated wall panel for construction is shown and described. The present invention is directed towards minimizing the labor of multiple additive steps using many layers and materials seen in many building envelopes.

In one example, the method comprises,

A series of prefabricated residential or commercial building panels made of any of varying materials such as hemperete, fiber, cellulose, plant material, bio-aggregate, aggregate, aerated concrete, composite or inorganic materials, of substantially solid body with channel shaped elongated voids substantially located at the vertical sides as well as horizontally across their top.

Said voids in one panel are a connected channel wrapping around 3 or more sides of the panel and exposed to the exterior of said panel. Said panels are placed side by side around the perimeter of a foundation aligning the channel shaped void in one panel with the respective channel shaped void in the panel beside it creating a concrete form, or form for a load bearing material. Said panels are left in place as an integral part of the wall system. Concrete or other load bearing material is placed in said voids substantially vertically between the panels and across their tops creating an air seal and a mechanical bond between panels. The resulting concrete shape inside the wall is a post and beam structure that is substantially equidistant from the interior and exterior of the wall minimizing heat transfer through thermal bridging and minimizing weathering to the concrete. Many of the requirements of a building's wall such as the insulation, the shear strength, the rough openings for windows and doors, the interior and exterior skin, utility chases, drip edges and trim details can be met by this series of prefabricated building blocks. A method of manufacture of the building panels, the product created by that manufacture, a method of panel assembly and integration with other building components, and the finished product created by the manufacture, assembly and integration with other building components are all shown in the present disclosure.

A system and method for primarily erecting curvilinear buildings using a plurality of interconnected structural tubes/sandwich panels is provided. Fabricating structural tubing comprises: connecting a fibrous and flexible lining to an inner surface of a flexible outer membrane, wherein the lining is saturated in a curable material that forms into a solid foam material when cured; and curing the curable material. Fabricating a sandwich panel comprises: connecting a first fibrous and flexible lining to an inner surface of a first flexible outer membrane, wherein the first lining is saturated in a curable material that forms into a solid foam when cured; connecting a second fibrous and flexible lining to an inner surface of a second flexible outer membrane, wherein the second lining is saturated in a curable material that forms into a solid foam when cured; and curing the curable material of the first lining and second linings.

A module, in particular for a building, includes a wall having at least two, preferably parallel, wall outer sides, which are spaced apart from one another. At least one channel is disposed between the two wall outer sides and is filled with a self-curing material. A building including at least one module, a method for producing a module, a method for producing a building wall and a method for producing a building, are also provided.

This invention relates to a self-supporting three-dimensional prestressed structure, as well as a method and a device for erecting same, to be employed in the construction of residential and nonresidential buildings. The structure is constructed of vertical form-defining flexible rodlike members (1) stressed during the construction of the structure, as well as horizontal flexible rodlike members (2) each forming a closed curve. The horizontal members (2) are also stressed during construction and welded or rigidly affixed by other means to the vertical form-defining members (1). Instead of horizontal circular members (2) the structure can be constructed completely or to some extent using a spiral member, also stressed during the construction of the structure that is rigidly affixed to the vertical form-defining flexible members (1).

A positioning device and method for producing a construction material body. The positioning device holds and orients a reinforcement body consisting of a textile reinforcement within a formwork. The positioning device comprises first and second holding part groups arranged on a main body. At least one of the two holding part groups is movable between holding and release positions. In the holding position, each holding part acts on an associated location of engagement on the reinforcement body. In the release position, the distance between the holding parts is different from the distance between the locations of engagement on the reinforcement body, such that the positioning device is brought into engagement with the reinforcement body or can be removed therefrom. In the release position, independent handling of the positioning device relative to the reinforcement body is possible. To switch between the holding and release positions, an actuation device is provided.

A method for producing a sustainable building without the use of heavy equipment. Such a building may include an adjustable foundation to eliminate the need to flatten the building surface below. The frame may be constructed by using hand tools to assemble pre-rolled galvanized steel rods. A pre-cut perforated galvanized steel sheet can then be laid on the frame and sheathed with a pre-mixed mortar that may be created by mixing materials easily found in impoverished countries, such as natural lime, river sand, white clay, and fly ash. The roof may be layered with a thin solar film to allow for the incorporation of solar cells to harness solar energy and may further include a rainwater collection mechanism to allow for the roof to also collect clean rainwater.

Methods and apparatus facilitate the construction of a building using prefabricated building units, each having a horizontal upper exterior surface and a plurality of vertical wall surfaces, wherein at least some of the prefabricated building units have at least one hollow column formwork structure. The prefabricated building units are lowered onto a pre-existing base at a construction site. A first story of the building is created by arranging a plurality of the prefabricated building units adjacent to each other on the base. Structural bearing material is applied to fill the hollow column formwork structures to create structural columns connected to the structural deck. Structural bearing material is applied to the horizontal upper exterior surfaces of the adjacent prefabricated building units to create a single structural deck over the prefabricated building units.

The present invention relates to a combination structure of permanent forms and a prefabricated steel assembly for a steel concrete composite member, the combination structure including: the prefabricated steel assembly having a plurality of shape steel members and a plurality of support bars; and each permanent form having a flat plate, L-shaped protrusions, a bent corner, and a L-shaped outer protrusion.

A building construction method uses wall frames having a moveable top track. The track is fixed in a raised position so as to be load-bearing during construction, allowing construction work to progress quickly. When supporting concrete columns have cured, the fixing can be released allowing the track to move into a lowered position and for the building load to transfer to the columns.
