A stay-in-place concrete formwork system allows stucco to be applied directly to the formwork, avoiding the need to provide a further surface treatment of the wall prior to applying stucco. Apertures are provided on an exterior facing wall of the formwork panel to receive and embed stucco therein. The panel may also be formed with outward stucco-engaging projections. Other features include using rigid insulation to brace the stucco and keep concrete from the apertures, a sealing joint element, extendible panels for use in curved formwork, rainscreen features and an alligator connector panel for adjustable lengths of formwork faces.

The present invention relates to a modular construction system with molding formwork or permanent formwork for concrete or reinforced concrete industry aimed at building construction. It Incorporates a number of key elements: structural-elements for forming flat walls, corner-elements, -elements connectors between the flat elements, auxiliary-elements of rectangular cross section which are located adjacent to the panels. Each cell has at least one of their edges a longitudinal rail and at the opposite end has at least one counter-rail so that they can connect adjacent elements. Along the inner surface of the flat structural elements exists at least one longitudinal rail in order to couple connectors between each pair of elements and stabilize the position. Once the final structure concrete is poured into the hollow interior of this cavity and flows through the perforations in the structure generating a textured finish that can also receive other materials for creating different types of coating.

A method for manufacture of a fire-proof and insulating prefabricated building wall comprising a wall core of an expanded, foamed plastic material, such as EPS (expanded polystyrene), with an integrated reinforcement structure and a coating of a cementitious material.

A building system and method of using the same may include a wall assembly including a plurality of expanded metal mesh sheets disposed on either side of at least one welded wire mesh sheet. The wall assembly may be disposed in a keyway defined by a foundation assembly including a plurality of form boards. The foundation assembly may be constructed and arranged for framing out a slab, wall, or structure. The building system may further include a framing assembly including a plurality of vertical supports spaced away from one another and being constructed and arranged to connect to a support header and plurality of spans such that a structure or wall may be formed within the framing assembly. Material, such as concrete, maybe poured between the plurality of expanded metal mesh sheets to form a slab, wall, or structure.

Disclosed is a spacer for a disposable formwork for the construction of a wall, with first and second panels. The spacer mutually couples the first and second panels at a certain distance one from the other. The spacer includes: a first connecting portion coupled, in use, with the first panel; a second connecting portion opposite the first and coupled, in use, with the second panel; and at least one pipe with at least one lateral opening communicating, in use, outside the formwork. In the pipe a through hole communicates, in use, with the formwork interior, allowing air passage from the outside towards the inside part and liquid outflow from inside towards the outside of the formwork. Also disclosed is a disposable formwork for the construction of a wall, including two panels and at least one such spacer, arranged between the two panels and coupling the two panels.

A wire netting device, in particular safety net device, includes at least two mutually engaging net elements, at least one net element of which is produced from at least one single wire, a wire bundle, a wire strand, a wire rope and/or another longitudinal element with at least one wire that is made at least partially of a high-tensile steel, the wire comprises at least one corrosion protection, in particular a corrosion protection layer and a portion of the wire (12a-g), in particular at least a portion of a wire mesh implemented of the wire, with the corrosion protection, in particular the corrosion protection layer, in a test run by an alternating climate test has a corrosion resistance of more than 1,680 hours, preferably more than 2,016 hours, advantageously more than 2,520 hours, preferentially more than 3,024 hours and particularly preferably more than 3,528 hours.

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.
