A truss (1) that comprises an elongate metal strip (10) and an elongate bar (12). The elongate metal strip (10) has a first longitudinally extending edge (14) and a second longitudinally extending edge (16). The first longitudinally extending edge (14) is in the form of a substantially serrated edge such that apexes (18) are formed along the first longitudinally extending edge (14). The elongate bar (12) is connected to the elongate metal strip (10) at the apexes (18) of the elongate metal strip (10) such that openings (20) are formed between the elongate bar (12) and the serrated edge of the elongate metal strip (10). A plurality of trusses (1) and one or more sheets of material (52), having trenches or channels (52) formed therein, may be used to make a permanent formwork element (50).

A system for assembling a transpiring, disposable heat-insulation shuttering mould and/or formwork used to cast a concrete surface, which includes at least one supporting plane featuring one upper surface on which a plurality of supports are arranged, which are suited to accommodate and retain (at least sideways inside themselves) at least one longitudinal or reticular portion of a tubular element.

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.

Various implementations comprise methods and apparatuses for constructing a concrete structure. An apparatus according to one implementation includes a structure comprising a pre-cast concrete component that includes at least one post-tensioning duct, a post-tensioning tendon extending through the post-tensioning duct, and a poured in place concrete surface disposed above and coupled to the pre-cast concrete component.

The present invention is a modular structural building system and method consisting of prefabricated, precast, composite reinforced concrete raised floor and steel beam panels with adjustable levelling connection assemblies between panels, supported by columns. The system has the ability to accommodate the use of the floor by construction personnel during the on-site assembly process. The perimeter of the raised floor slab can be provided with ducts for a field installed conventional reinforcement means to create a continuous structural diaphragm for the floor panel.

A thermal insulation plate (1), which is manufactured from cellular plastic, and the upper surface of which comprises grooves (5a, 5b), which are arranged in two directions over the area of the entire surface. The thermal insulation plate comprises at least in part of the groove (5a, 5b) intersections a spacer (6, 6a, 6b) for installing reinforcement, which is formed from thermal insulation material as a fixed part of the thermal insulation plate.
