A structural wall panel includes an elongated shared structural framing member and one or more elongated intermediate structural framing members. An elongated top track is connected to a top end of each of the framing members. An inner sheet of suitable sheet material may be secured to the framing members so as to form an inner face of the structural wall panel, while an outer sheet of suitable sheet material may be secured to the framing members so as to form an outer face of the structural wall panel opposite the inner face. The elongated top track and inner and outer sheets are aligned on the framing members so as to form a male receiver at one lateral side of the panel and a female receiving structure along the opposite lateral side of the panel.

A semi product for building panels or structural elements comprising several wood lamellas (5) fixed by distance elements (4), a building panel with such a semi product and a method of producing the semi product and the building panel. A method of producing a semi-product for a structural element or for a core for a building panel, wherein the method comprises the step of: attaching at least two distance strips by an adhesive to a first wood board; attaching a second wood board to the distance strips by an adhesive; and cutting the first and the second wood boards and the distance strips in the length direction of the wood boards.

A modular floor for providing support to a vehicle and/or a crowd on an uneven or soft subsurface of a supporting terrain is disclosed. The modular floor comprises at least two planks, each plank comprising a top and a bottom plate separated by a plurality of spacing plates. A first plank comprises a male connection element and a second plank a female connection element to interconnect the first and second planks. The connection elements are configured to extend a modular floor of interlocked planks both at an edge comprising a male connection element as well as at an edge comprising a female connection element. Preferably, a plank is a single-piece component, comprising aluminum alloy or plastic.

What is presented is a unit cell comprising a cellular geometry that comprises cell walls and cell edges arranged into a combination of a cubic cell geometry and a tetrahedral cell geometry arranged to have a coincident central vertex. The cubic cell geometry comprises three orthogonal cell faces that intersect at its central vertex. The tetrahedral cell geometry comprises an arrangement of eight tetrahedral cells that share its central vertex such that each tetrahedral cell shares three coincident edges with three other tetrahedral cells in a cubically symmetric arrangement. The tetrahedral cell geometry is combined with the cubic cell geometry such that all vertices of the tetrahedral cell geometry are coincident with the vertices of the cubic cell geometry.

A panel is disclosed for use in construction. The panel comprises opposing surfaces that extend between first and second opposite ends. The panel also comprises a plurality of parallel (e.g. sawtooth) ridges. The ridges are provided on at least one of the opposing surfaces. The ridges extend along and adjacent to a first of the opposite ends of the panel for at least a part length thereof. The ridges are arranged to engage with and move past corresponding ridges of an adjacent panel when the panels move relative to each other in opposite directions. The ridges are further arranged so as to interfere with the ridges of the adjacent panel to resist relative movement in a reverse of the opposite direction.
