The present relates to a device being used in modular building construction comprising at least one flat load support comprising a first main face and a second main face, at least one elongated load support designed for being coupled with said flat load support. The device is characterized in that said flat load support comprises an array of transverse openings extending through the thickness of the flat load support. The flat load support is arranged for fastening said flat load support with said elongated load support at any position corresponding to one of said opening in a reversible manner and to any position between said openings in a reversible manner. Each flat load support comprises reversible lateral connection means and/or reversible transversal connection means for coupling flat load supports in a reversible manner. The flat load support and the elongated load support are arranged for being detachably assembled to provide the modular, reversible, and/or versatile building construction. The invention further relates to a modular construction building based on said device and to a method using said device.

Structural plates and methods of constructing arch-shaped structures using structural plates. Structural plates may include a combination of features including: an outer structural plate having adjacent circumferential apertures respectively spaced nominally greater than adjacent circumferential apertures of an inner structural plate; and the outer structural plate having nominally 5 enlarged or differently shaped circumferential apertures (as compared to circumferential apertures of the inner structural plate) such that the embodiment structural plates may be radiused to a variety of different radii while achieving desirable overlapping alignment of apertures along overlapping circumferential edges for receiving fasteners therein. Joiner plates may be provided for interconnecting structural plates along transverse edges in a non-overlapping arrangement, 10 thereby reducing the quantity of structural plate material that otherwise would be needed for a given circumferential length of the arch-shaped structure.

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 fastening apparatus for two or more prefabricated blocks, in which the apparatus includes a perforated plate, a first block with a step, a connector plate that sized and shaped to engage the step, and an upstanding wall that is spaced apart from the block member. The perforated plate is connected to the wall and extends away from it towards the step. The perforated plate is partially mounted on part of the connector plate so as to sandwich it between the perforated plate and the step.

An engineered wood product with at least one engineered-wood substrate or core layer (such as, but not limited to, OSB), with a connectivity layer configured to reflect RF signals (e.g., wifi and/or cellular signals), thereby enhancing connectivity in adjacent or proximate spaces or areas. The connectivity layer may be a metallic material, such as, but not limited to, aluminum or copper. The layer may be a sheet or film or foil of the metallic material applied to the surface(s), or integrated into the interior, of the substrate or core layer. The layer also may be a coating or deposited layer. A connectivity layer may be “sandwiched” between two or more engineered-wood substrates, thereby forming a composite panel or product. The surface of the connectivity layer may be embossed or patterned.

Electromagnetically shielded and self-supporting panels form a shielded enclosure. The use of prefabricated, shielded and self-supporting panels to construct an enclosure reduces the time and cost of constructing such an enclosure.

Described herein is an stain and sag resistant acoustic building panel comprising a porous body formed from building material and latex binder, wherein the building material may include fibers and filler and at one of the building materials has been pre-treated with a charge-modifying component, thereby enhancing the sag-resistance of the building panel.

This invention relates to prefabricated, lightweight, multi-component structural modular building panels and modular building systems. The said panels are framed with edge members that have a unique connecting shape, making them modular. The multi-component panel allows for design flexibility and the mass manufacturing of its components. Connectors serve as a link to assemble the panels together, and to connect them to corners, floors or foundations, roof panels and the roof apex member, and or other conventional construction elements. Connectors and members, all with unique connecting shapes, coupled with the said panels, create a structural wall, roof, similar structure or building system. Assembled panels and members incorporate the primary building structure and the building envelope. The assembled panels, members and other components of the building system, in part or whole, can be flat packed for easy transport and shipping, and can be assembled quickly and easily with semi-skilled labor.

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).

A method of constructing a reinforced concrete floor structure or wall structure, including: fabricating a precast panel substantially from concrete including a first set of parallel conduits extending through the panel, wherein the conduits open to opposite sides of the panel; moving the panel into its final position on a building site; and inserting tensioning cables through the conduits and tensioning the precast panel in the direction of the conduits to form a reinforced floor structure or wall structure, and a dowel connecting system for joining adjacent precast building panels, the system comprising elongated hollow dowel members cast in at the edges of two or more precast building panels such that when the building panels are positioned adjacent to each other their respective dowel members are co-linearly aligned; and a dowel piece to be inserted into a recess of the co-linearly aligned dowel members and to extend across the building panels, wherein the recess of the dowel members is adapted to be filled with grout to anchor the dowel piece therein and thereby structurally joining adjacent building panels.
