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).

The disclosed technology provides a module useful in constructing an energy efficient, durable building structure, the module including walls to form a vacuous, sealed chamber substantially void of structural elements, materials and gaseous molecules. One or more ribs are affixed to or formed integral with an exterior surface of the exterior wall of the module, extending the width of the module. The disclosed technology further provides a vacuum apparatus which may be incorporated in communication with the vacuous, sealed chamber, for creating and maintaining a vacuum within the module. A method of controlling heat transfer within a structure is also provided, utilizing the modules as herein disclosed, each module being coupled with a vacuum apparatus in communication with the vacuous, sealed chamber, for creating and maintaining a vacuum within the module.

A method for forming a building includes obtaining a mould, spraying a first spray material onto the outside of the mould so that it sets generally in the shape of the mould to provide a core. The core has side walls, and end wall integral with the side walls and a roof integral with both the side walls and end wall. A second spray material different to the first spray material is sprayed onto the inner and outer surfaces of the core to give it a rigid skin.

Stay-in-place forms and methods and equipment for installing thereof. A concrete form includes a vertical component and a horizontal component, the vertical component located substantially perpendicular to the horizontal component. Also, the form includes an interior surface, at least a portion of the interior surface providing a form for supporting uncured concrete; wherein the uncured concrete forms a concrete structural portion upon curing of the uncured concrete; and wherein the interior surface remains attached to the concrete structural portion after curing. The form may include inserts and compatible form attachments. Also, forms including recesses may be utilized to reduce the weight thereof. Lifting equipment and accessories may be utilized to lift the form from a form holder and set same in place. Forms contain the work area as soon as it is installed to minimize fall hazards and the time, costs, and downtime associated with installation of safety measures.

The present invention relates to methods and apparatuses for an automated reinforced concrete construction system for onsite slip-form molding and casting a variety of cementitious mixes in a cast in place leave in place externally moldable flexible reinforced containment sleeve providing a wide variety of interchangeable full-scale molding configurations simultaneously optimizing a wide variety of cementitious mix curing characteristics, further having optional internal reinforcement net(s), for layer wise interlocking additive printed brick deposition providing improved slip-form mold casting of a wide variety of reinforced concrete structures; the present invention further includes a variety of operating platforms suitable for on and offsite construction as disclosed herein.

A flexible panel includes: a plurality of first blades made of semi-rigid material, of rectangular shape, having a pair of long sides and a pair of short sides; a pair of textile membranes which connect each pair of said first blades along said long sides; each of the plurality of first blades include at least one second blade, of quadrilateral shape, connected in a folding manner to one of the short sides, along a line of contact between one of the plurality of first blades and the at least one second blade; when the panel opens it creates vertical tubular hollow areas laterally delimited by the plurality of first blades and by the one pair of textile membranes which joins them.

Method of fabricating a 3-dimensional structure, mesh formwork element for fabricating a 3-dimensional structure, and method of fabricating the same. The method of fabricating a 3-dimensional structure comprises providing a mesh formwork element such that a cavity bound by at least two opposing portions of the mesh formwork is formed; accumulating a material in the cavity; and allowing the material to harden; wherein apertures in the at least two opposing portions of the mesh formwork element are adapted to the hydro-static pressure of the accumulated material or vice versa such that at least two surfaces of the hardened material substantially take on the respective shapes defined by the two opposing portions of the mesh formwork element.

The present invention corresponds to a formwork mechanism for casting and molding concrete, comprising a coffer having a sheet and four plates arranged around the sheet perimeter. Each plate has holes arranged on its front face. Also, the formwork mechanism includes a structural element, connected to one of the plates by fixing means. On the other hand, the structural element has lateral perforations that are aligned with the holes of one of the coffer plates. Fixing means pass through the holes and side holes. The structural element may be a beam, a three or four-beam T, and combinations thereof. On the other hand, using several coffers interconnected with structural elements, formworks are constructed for casting flat reticular slabs; and also for curved reticular slabs with greater slab thickness near the beams supporting the slabs in comparison to the span of the slabs.
