An underfloor storage system is disclosed. The storage system comprises a frame with a storage box and at least one raise/lower mechanisms to raise and lower the storage box. A raise/lower mechanism include at least one winch driven pulley system. The storage box includes a floor. Raising the storage box provides access to underfloor storage. In a preferred embodiment, each winch driven pulley system provides an ideal mechanical advantage of 4 and includes an additional pulley which is configured to pivot relative to the winch and thereby adjust the orientation of the pulley to the winch as the line tracks across the winch during wind up or let out of the line.

A prefabricated structural panel is for a structural construction system. The panel defines a panel plane with a peripheral edge for connections, and includes a load-bearing frame made of concrete, steel or wood substantially coplanar with the panel plane. The load-bearing frame defines a through opening transverse to the panel plane. The panel includes a blind or glass filling layer in the load-bearing frame to close the through opening. The panel is completed in an assembly line with layers of different materials assembled on both sides of the load-bearing frame and the filling layer, on an inner side of the filling element. A covering layer fixed to metal profiles defines a gap for air circulation. Layers of isolating materials create thermal and acoustic insulation on an outer side of the load-bearing frame and filling element. The prefabricated panels are assembled by a geometric interlocking coupling and form housing units.

Primary shell structures consisting of plane load-bearing modules made of elements consisting of upper and lower secondary shell elements spaced apart from each other and joined by means of statically necessary filling bars, which include crossbars and diagonal bars, to form a double-shell plane load-bearing structure in the form of a primary shell structure

A method for building a mechanical secured block structure, including placing a footer block on a desired surface, inserting two respective starter bar nuts into the footer block, inverting the footer block, placing a first concrete masonry unit over respective first and second anchor bars, aligning the first concrete masonry unit with the footer block, placing second and third footer blocks adjacent the first footer block, placing a second concrete masonry unit adjacent the first concrete masonry unit, positioning each respective concrete masonry unit to equally straddle two adjacent footer blocks, positioning respective anchor bars atop respective concrete masonry units, and bolting respective concrete masonry units to respective footer blocks to interconnect the two respective concrete masonry units and the three respective footer blocks to define a contiguous wall. Each respective masonry unit and each respective footer block are post tensioned to be under compression.

A mechanism for supporting and positioning a glass floor unit relative to a base utilizing a support positioned to contact the glass floor unit. An adjuster interacts with a receiver fixed to the base. The adjuster includes a contact element which moves the support and exerts a force against the glass floor unit in an upward direction.

A portable pavement system allowing for fast and easy installation of a pavement surface that incorporates individual pieces working together to create a solid, durable, adjustable, reusable, and removable platform for use as a parking or driveway facility, or other uses where such a surface possessing the special qualities described is advantageous.

Modular building methods and systems using precision machined modular panels. Standard modular panels can be used for constructing walls, floor, and roof, with transitions from wall-to-roof and wall-to-floor provided by special transition panels. All panels are pre-slotted to include a channel configured to receive flange(s) of a C-channel member. The present method progresses by assembly of a frame formed from C-channel frame members connected with overlap connections, followed by insertion of foam panels into flange(s) of the C-channel frame members, followed by insertion of another C-channel frame member into a slot on the opposite end of the panels, with such steps repeated, to form the building. Such alternating placement of panels and C-channel frame members eliminates the need for a tape measure, any independent frame for the building, and ensures the walls, floor, and roof are plumb.
