The present invention relates to a prefabricated construction system and method, for erecting constructions by means of the assembly of prefabricated structural elements obtained by cutting flat materials, forming structural nodes by means of coupling at least a first coupling configuration formed by first slots made in a plurality of parallel boards forming a first structural element with at least a second coupling configuration formed by second slots made in a plurality of parallel boards forming a second structural element, providing a structural core in the form of an array having interstitial openings going through it which allow the coupling of third and fourth coupling configurations of third and fourth structural elements.

A simplified framing system with two or more arches which are joined together into a unitary structure by means of connector elements. Each arch is joined to a base by means of connector elements herein termed “base frame connectors”. The angle frame connectors and base frame connectors are preferably fabricated from sheet metal by conventional die cutting and press-forming or stamping techniques. The simplified framing system of this disclosure is particularly designed for assembly using nominal 2×4 inch lumber. The system does not require cutting the lumber except for straight, perpendicular cutting of the lumber to the desired lengths.

An engineered wood structural system including multiple vertical structural elements including first seats comprised between parallel vertical struts made of successive aligned vertical strut segments connected to each other, multiple horizontal structural elements, supported on the first seats, each including an upper horizontal board and a lower horizontal board with at least one second spacer placed in between, and optionally slab members supported on the horizontal structural elements defining at least one structure floor.

A construction system includes a set of constituent elements, at least one of which includes at least two superimposed folds each including at least two wooden structural boards. In this system, at least two constituent elements are fixed together by a non-adhesive fixing device and at least two adjacent folds are held against each other by non-adhesive holding device. The faces in contact with two structural boards are at least partially provided, at their contact interface, with a set of grooved patterns arranged so as to prevent the structural boards from sliding one relative to the other along at least one first immobilisation axis. A method for manufacturing such a construction system is also disclosed.

A frame truss made of two walls and a roof structure. Each of the two walls have an outer and inner chord. The outer and inner chords of each respective wall are not parallel, but the inner chords of the two walls are parallel to each other. The arrangement of the inner and outer chords of each wall creates an exterior overhang with respect to the ground. Each of the walls converge at their bases and are attached at their bases to a plate. The roof structure attaches to the top of each of the walls and spans between them creating a frame that can be assembled in conjunction with similar frames to construct a building system.

This invention relates to a demountable cassette construction system for building a structure comprising one or more demountable cassettes, wherein the or each of the one or more demountable cassettes are attachable to one or more adjacent demountable cassettes via demountable joints, wherein the demountable joints permit the one or more demountable cassettes to be removed from a structure without removal of and/or damage to the or each of the one or more adjacent demountable cassettes.

A modular system for the dry building of structures for constructions, such as walls, floors, balconies, roofs or the like, includes a plurality of planar modular beams that define a respective plane and that are mutually jointed, and a plurality of planar panels anchored thereto at least at or in proximity of the end portions of the same planar modular beams.

E.sup.3Lumber is comprised by novel apparatuses as engineered wood systems, methods, apparatuses, tools, adhesives, and manufacturing for construction of structures. E.sup.3Lumber has standardization and optimization surpassing state-of-the-art construction. Each of those systems, methods, apparatuses, material compositions, and material stratifications utilize one-to-many apparatus relations. All formed or machined apparatuses feature innovative features like engineered constraints, multi-tier and hybrid composites, and constrained assembly all situated within novel methods like, the Three E, 4-Tier, Cross Datum Construction, E-Stud, E-Framing, E-Truss, E-Hips, E-Bridging, Continuous Truss methods meet national and international specifications. The Three E's of E.sup.3Lumber are environmental, economic, and engineering and are characteristics found throughout invention intended for the significant improvement of environmental conditions, wood products, and technologies. As a fact, E.sup.3Lumber use decreases deforestation by increasing growth periods of trees by decreasing biomass consumption and all the while providing economic incentive to become greener.

A method for constructing wooden framing for a structure is provided. The method includes locating a base on a horizontal surface, providing a wooden vertical framing support element on the base, installing a horizontal support member between the wooden vertical framing support element and one other wooden vertical framing support element, adjusting at least one of the base and the wooden vertical framing support element to have precise spacing between the wooden vertical framing support element and the one other wooden vertical framing support element, and securing the base to the horizontal surface and the wooden vertical framing support element to the base.

A wooden structural joint is provided, including a wooden rectangular base member comprising, at one end, a removed center element, a plurality of removed center edge elements, and four intact corner elements, where the removed center element and the plurality of removed center edge elements are formed from vertical and horizontal cuts into the one end of the wooden rectangular base member, a plurality of horizontal members, each horizontal member having a height and further having a tab cut therein at one edge of the horizontal member, the tab cut at a percentage of the height such that all horizontal members fit securely together when assembled within the wooden rectangular base member, and a wooden rectangular top member having one end cut similar to the wooden rectangular base member.
