Flexible extrusions of selected die patterns may be slid or snapped together to create bundles of slidably-interlocked extrusions that may be used to create structural components for architectural and a plurality of other construction purposes. Components such as standard rectangular construction beams, arches, domes, architectural trees, cylinders, molds, puzzling mazes, furniture, rollercoaster track, and other applications are illustrated and described in embodiments herein. Bundles of slidably-interlocked extrusions may be formed into a straight beam, bent into an arch, or twisted into other forms as desired. Bundles of slidably-interlocked extrusions may for example, comprise subsets of different length bundles of extrusions that may extend the length create long-span support beams or that may branch away at an angle from the starting beam to form a treelike structure.

Systems, methods, and devices of the various embodiments may enable manufactured modular construction. The various embodiment manufactured modular construction systems, methods, and devices may offer a solution to the housing shortage worldwide that is less than half the cost of the cost of current modular buildings. Various embodiments may include interlocking vertical and horizontal elements. Various embodiments may include a locking system pulling upper horizontal elements of an embodiment modular building toward lower horizontal elements and/or a foundation or a lower floor of the embodiment modular building to thereby lock vertical elements and vertical panels in place between the upper horizontal elements and the lower horizontal elements, foundation, and/or lower floor. In various embodiments, the locking system may include a shock absorber.

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.

The present invention concerns a construction system for a building module, whose main elements are made of plastic material, providing a robust construction in an easy and quick manner. The system includes a set of main beams (1) adapted to be assembled end-to-end to form an open structure in the shape of a 3-dimensional rectangular frame. The system further includes secondary beams (11), adapted to be assembled between parallel and opposite main beams, and flat facade elements (3) insertable against each other between two adjacent parallel beams. Each facade element (3) includes a rectangular flat plate provided with two folded opposite edges (3A) intended to be hooked with adjacent parallel beams. Each main beam has a rectangular cross-section including, on the four sides thereof, a projection (21) parallel to the side and spaced therefrom leaving an opening to receive a folded edge of a flat facade element. Each secondary beam (11) includes, on two opposite faces, at least one projection leaving an opening to receive a folded edge of a flat facade element (3).
