A portable support platform may include a plurality of elongate segments arranged substantially parallel and adjacent to one another. The segments may be configured for spanning a space between two support points to support a user. The platform may also include a tying portion configured for flexibly securing the plurality of segments together. The platform may be arranged in a substantially flat open position for supporting a user and a substantially rolled up closed position for convenient transport and storage.

Devices, structures, and methods for designing, constructing, and fitting modular structural building blocks together into a unified structure. Modular blocks are rapidly fit together into finished assemblies. Finished assemblies include reinforcing elements aligned in a structurally sound pattern. The unified structure includes walls, provisions for corners, and provisions for door/window spaces. The unified structure optionally includes raised floors or lowered ceilings, offset from ordinary associated height, using blocks disposed side-by-side with intermediate supports. The unified structure optionally includes one or more curved structures, such as vaulted ceilings, rounded walls or silos, tunnels, or otherwise.

An underlay mat (10) for floor coverings, includes a polyurethane layer (14), a nonwoven backing (18) on the underside of polyurethane layer (14), a self-adhesive film (20) on the topside of the polyurethane layer (14) and which includes a carrier film (12), a layer of adhesive (22) applied to carrier film (12), and a mesh structure (24) made of fibers which is embedded in the adhesive layer (22), and a removable protective film (26) on the topside of self-adhesive film (20).

An architectural building block system including a block having three side walls, each having an inside surface and an outside surface, the three side walls cooperate to form a triangular tube, the outside surface of each of the three side walls extending from the inner surface to the outer surface and the inside surface of each of the three walls is disposed substantially at right angle to each of the inner surface and the outer surface; and three channels, each channel disposed on one of the three side walls on the inner surface, wherein each channel extending from the inside surface to the outside surface of one of the three side walls and each pair of the three channels configured to receive a rebar.

A flooring system configured to be installed in a multi-story building wherein the flooring system is operably coupled with a portion of the superstructure of the building. The flooring system includes a first layer of corrugated metal panel that is position in a horizontal orientation and is operable to superposed at least a portion of the superstructure of the building. A plurality of mounting studs are secured to a portion of the superstructure of the building and extend upward through the first layer. A second layer of corrugated metal panel is superposed the first layer and secured thereto. The second layer has an adhesive layer applied to the upper surface thereof. A third layer is superposed the upper surface of the second layer. The third layer is manufactured from a different material than the first and second layer. A structural foam layer is injected intermediate the third and second layer.

Disclosed is a multiple layer substrate that can be used with a top asphalt applicator that eliminates the need for a bottom asphalt applicator and fines applied to the bottom asphalt layer. A low porosity or impermeable bottom layer prevents the flow of asphalt applied to the porous top layers of the substrate from penetrating the bottom surface. This eliminates the need for fines to prevent sticking of shingles in a shingle stack. In addition, substrate layers that combine fiberglass and polyester fibers in various configurations provide a substrate that can be used in typical shingle manufacturing and manufacturing of waterproofing products that is impact resistant.

A method of assembling resilient floorboards is disclosed that includes the step of bending an edge of a floorboard during the assembling. The bending reduces the force required for connection of the edge to another edge of a juxtaposed floorboard. The floorboards may be provided with a mechanical locking system for vertical and horizontal locking of two adjacent floorboards.
