Disclosed is a structural element including of interlocked resilient sheet material components, with each sheet operatively forming a component by being shaped to provide an elongate base with two opposing edges from which a first extension and a second extension respectively extend, with the second extension extending further from the base than the first extension, with the first and second extensions being provided with complimentary interlocking means operatively enabling the extensions of one sheet material component to be interlocked with the extensions of another sheet material component; with the extensions of four sheet components being interlocked, each at a right angle with at least one extension of another one of the sheet components, operatively for four sheet components to provide the structural element with an elongate open-ended core with a plurality of elongate open-ended ribs spaced around the core with each rib being longitudinally aligned with the core.

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.

A construction method for a building is provided that includes the steps of: hoisting and positioning a plurality of precast columns on at least a portion of a predetermined area of a construction site to form a precast column array having at least two spans along a first direction and one or more spans along a second direction substantially perpendicular to the first direction; positioning the pre-fabricated beam rebar assemblies between adjacent precast columns, positioning each of the precast slab panels on support potions on the precast columns, assembling the beam cage and pouring the concrete into the molds for the beam cage to accomplish the structure of a single story; and repeating the steps of constructing the above-mentioned precast column array until completion of the structure of all stories of the building.

Disclosed are a wall construction system with drywall composite columns and a method for constructing walls using thin sheet steel sections in concrete composite construction for erecting story-high walls with at least one-sided planking with building boards, in particular for residential buildings. Structural loads of solid ceilings and facade walls are absorbed via the composite columns arranged in a modular grid within the wall plane. The joining of the composite columns takes place at the column head over a concrete beam on which the ceiling rests. In-filling wall or facade elements may be arranged between the composite columns. The composite columns include a concrete composite column with a sheet metal reinforcement and a spatially offset thin-walled sheet steel section for mounting drywall thereto even after the metal reinforcement has been filled with concrete. The sheet metal reinforcement and the thin-walled sheet steel section may have different material qualities and thicknesses.

The invention relates to a system for erecting a building structure, the system comprising a foundation for receiving the building structure, and a plurality of inner and outer walls, roof and floor panels, the panels being adapted to engage each other for defining at least one story of the building structure, wherein the foundation comprises a first section and a second section, the first section being adapted to bear the load of the building structure and the second section being adapted to provide access to the interiors of the building structure.

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.

A wall construction includes a number of spaced apart, upright channel-shaped studs having open upper ends, and a number of panels forming an exterior wall. The panels have tie members that extend into the studs. An elongate support member is attached to the studs adjacent to the upper ends of the studs. The support member does not block access to the upper ends of the studs so that the studs can be filled with concrete with the support member remaining in place attached to the studs.

A construction system definable in terms of an X, Y, and Z coordinate axes which provides a first part having a hollow three-walled web elongate in the Z axis, having a series series of securement brackets with geometric cut-outs on the upper Z edges of the elongate Z axis member; and a second part having at least one open end for complemental engagement of the first part wherein the second part may fit over distal ends of said first part in which a cross-section of the second part is generally that of the first part, but wide and tall enough to allow the first part to slip within the second part, and said second part having an opposite end of said opening, wherein said second part securing the first part to a structural support.
