Disclosed is a modular building system including, in some embodiments, one or more wall panels, one or more floor panels, and one or more roof panels. The modular building components of the modular building system including the one or more wall panels, the one or more floor panels, and the one or more roof panels can form housing or storage structures with electrical wiring, plumbing, or both wiring and plumbing. The housing or storage structures can be erected by one or more persons without a need for a plumber, an electrician, or power tools. Also disclosed is a method for erecting one or more housing or storage structure in accordance with the modular building system.

A building system may include at least one diaphragm beam having opposite ends connected to an external structural frame of a building, at least one pre-assembled floor-ceiling panel adjacent to a vertical side of and coupled to the diaphragm beam, and at least one pre-assembled wall adjacent to a horizontal side of and coupled to the diaphragm beam, The diaphragm beam may be filled with a mineral-based material, such as concrete. The one or more pre-assembled floor-ceiling panels may each include a plurality of joists extending perpendicular to the diaphragm beam, a floor-panel including at least one metal layer attached to the joists on a floor side of the pre-assembled floor-ceiling panel, and a ceiling panel including at least one layer comprising mineral-based material attached to the joists on a ceiling side of the pre-assembled floor-ceiling panel. The one or more pre-assembled walls may include interior and/or exterior walls of a building.

A method of assembling a building unit in accordance with a floor plan of a building using prefabricated components may include installing a first prefabricated floor panel in a first position of the building unit, the first floor panel being selected from a first plurality of prefabricated floor panels having a same first width; installing a second prefabricated floor panel in a second position of the building unit, the second floor panel being selected from a second plurality of prefabricated floor panels having a same second width; and installing a third prefabricated floor panel in a third position of the building unit, the third floor panel being selected from a third plurality of prefabricated floor panels. The floor panels in the third plurality of prefabricated floor panels may have different widths. The third floor panel may be selected such that a sum of the widths of the first, second, and third floor panels corresponds to the total width of the building unit in accordance with the floor plan.

The disclosed invention is a permanent, low-profile outdoor stage that resulted from achievement of objectives to build a home-based site for developing performing artists to practice their art. The stage's performance floor simulates floor-features on which users normally carry out training, recitals and competitions. Between practice sessions the stage can be left uncovered and unattended without being damaged by environmental elements while still retaining its desired original structural and functional qualities. The stage's novelty pertains to composition of its performance floor that is made of matte-finished high-density polyethylene, and the process by which this surface is anchored to the stage's rigid base. The stage is functionally spacious, strong and safe. This stage's novel performance floor, its potential extended utility, its durability against outdoor environmental conditions, and its carefree maintenance combine to make the invention unique in its field.

Disclosed is a rollable platform that may be unfurled in any orientation over exposed floor or ceiling joists. The platform may be constructed of a specific arrangement of support surface panels and underside joint panels to give the platform both (a) rigidity in a direction that is normal to the support surface via gridlock between the support surface panels and (b) foldability and/or rollability in a direction that is normal to the underside joint panels due to hinged interconnection.

A modular biofiltration support system for a bed of organic filter medium, formed of a multiplicity of rectangular bed platform modules or floor tiles, provides for bridging across an air/gas supply trench which can be up to 36 inches or even 48 inches wide. The bridging sections, formed of a mix of recycled plastic materials in a high-pressure molding operation, interconnect with edges of the floor tile assemblies on each side of the trench, and also engage with one another at sides. Each module is a high strength beam.

A method of supporting an upright member from a support surface includes inserting an elongated carrier of an upright member support system into a hole in the support surface. A base of the support system is positioned at least partially around the carrier so the base contacts at least one upper surface of the support surface. A lock of the support system is releasably engaged with the carrier above the base and tightened down sufficient to maintain the base in contact with the support surface. The upright member is inserted into a bore of the carrier.

An outdoor wood decking board for use in construction of an outdoor deck floor, the outdoor decking board including a wood core formed from a first wood species of common grade wood species as a three-dimensional solid rigid body. A facing wood veneer formed from a second wood species of superior grade wood species as a three-dimensional solid rigid wood finishing layer permanently seamlessly attached via an adhesive to a first wood face of the wood core thereby the wood core having an appearance of the second wood species. In another embodiment, the facing wood veneer is formed from a third wood species, exotic hardwood species. A two-part emulsion polymer isocyanate adhesive is used to bond the wood core against the facing wood veneer; to bond two wood cores together. In another embodiment, the adhesive is a two-part polyurethane emulsion polymer.

System for supporting an upright member from a support surface includes an elongated carrier releasably engageable with the support surface, a base adapted to extend around at least part of the lower end of the carrier and abut the support surface and at least one anchor associated with the carrier and configured to grip the upright member when the upright member is inserted into a bore of the carrier.

Compound structure made of composite material, such as fiber-reinforced polymer resin, comprising first oblong elements reciprocally distanced and parallel to each other and second oblong elements reciprocally distanced, parallel to each other and crisscrossed with respect to the first oblong elements. The first oblong elements and the second oblong elements are made in a single body to define a reticular structure with a monolithic flat shape
