A kit of modules of a framework, each module comprises struts connected among each other, each strut comprising a first and a second side, the modules being connected by a set of fixing elements and comprise each at least two gussets placed on two adjacent struts, each strut being provided with at least a first and a second perforation, said gussets being provided with a third perforation and extend in parallel to the second side of the struts, the third perforation being oriented along a direction which crosses the second side, a first respectively a second fixing element of said set being housed in the first respectively the second perforations of two modules when they are assembled side by side with their first sides of the struts of each of the two modules, which fixing elements are provided for enabling to establish a connection between the two adjacent modules while they are connected to each other.

A set of structurally insulated panels and method of building construction, the set of panels having an indexing system that allows for any one panel to be easily attached to any other panel via indexing pins placed in pre-arranged openings. The indexing system enables essentially any number of panels to be assembled in essentially any reasonable manner to construct a building structure.

A wall assembly is manufactured for supporting an exterior covering of a structure. The wall assembly includes a frame assembly including a top member and a bottom member spaced from the top member. The frame assembly further includes a plurality of vertical members spaced from each other and coupled to and extending between the top and bottom members. The plurality of vertical members each have an exterior surface configured to face an exterior of the structure. A rigid foam layer is directly coupled to the exterior surface of the plurality of vertical members. A sheathing layer is coupled to the rigid foam layer opposite the plurality of vertical members with the sheathing layer configured to receive the exterior covering.

Foam wall structures and methods for making them are described. The wall structures include a frame, a foam panel overlying a front surface of the frame, and a polyurethane foam layer disposed in a cavity of the wall structure. The polyurethane foam layer has a density, as determined by ASTM D1622-14, of at least 44 kg/m.sup.3 and exhibits ASTM E84-16 Class A flame spread and smoke development characteristics. The polyurethane foam layer is the cured reaction product of a polyurethane foam-forming composition that includes a polyisocyanate, an aromatic polyester polyol having a functionality of greater than 2.5 and an OH number of at least 300 mg KOH/g, which is present in an amount of at least 50% by weight, based on the total weight of the polyurethane foam-forming composition less the weight of the polyisocyanate, a catalyst, and a blowing agent composition. The blowing agent composition includes water and a hydrofluoroolefin.

A watercraft storage structure for storing a watercraft comprises a plurality of supports, wherein each support includes a clamping bracket; a shelf slidably attached to the plurality of supports by the clamping bracket attached to each plurality of supports forming a watercraft storage area; and a support platform positioned within the watercraft storage area, wherein the support platform is adapted for supporting a watercraft; wherein the each clamping bracket includes a first plate and a second plate that operate to press against the support forming a frictional fit with the support.

A structural assembly using at least one anchor assembly for attaching a first structure to a second structure is described. The anchor assembly has a body having a first face and a second face. The first face is transverse to the second face and has an elongate slot. The second face has a through hole. The body is fabricated from a material that fails at a temperature in excess of 1,000° F. A fastening member is positioned in the elongate slot for connecting the first face to the first structure and for sliding engagement with the elongate slot in response to relative movement of the first structure and the second structure.

A wooden panel component (1) is provided having at least two layers (4) of cross-pieces (5) arranged within its frame (2). The cross-pieces (5) are orientated obliquely to opposing frame sides (6,7) of the frame (2) for bracing the wooden panel element (1) and the frame (2) thereof.

Certain exemplary embodiments can provide a wall frame comprising a top plate, a bottom plate, a first end column, a second end column, a plurality of studs, and a plurality of purlins. Each of the plurality of purlins is an edge of a pair of cells, the pair of cells having edges comprising three edges that comprise one or more of a part of the top plate, a part of the bottom plate, a part of the first end column, a part of the second end column, a part of the plurality of studs, and another of the plurality of purlins.

The invention relates to a method of manufacturing a prefab construction element (11), preferably a load-bearing element, for frame construction, such as wood frame construction, comprising the steps of providing a roofing, flooring or wall panel (2), which panel (2) comprises an enclosure (3), providing a fungus and a substrate, introducing or preparing a mixture (10) of the fungus and the substrate, in the enclosure (3) and allowing the fungus to grow to form a network of hyphae through the mixture (10) and into the walls (4-7) of the enclosure (3) to form a mycelium composite, and drying the composite while it remains in the enclosure (3) of the panel (2).
