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.

Method of making construction materials intended for use as structural elements, such as structural blocks, used in the construction of buildings and civil engineering structures. In one aspect, the blocks may comprise a body shape configured so as to allow it to interlock with other blocks in the construction of a structure. Methods for manufacturing the blocks and structures comprising such materials and methods for building such structures are also disclosed.

An anchor arrangement for mounting to a membrane skin of a structure has a mounting bracket, including a mounting flange provided with one or more fixing apertures and a metallic rigid mounting plate arranged to underlay the anchor mounting bracket and provided with one or more fixing apertures arranged to match up with the aperture(s) in the anchor mounting bracket. A membrane layer lies contiguous with the metallic rigid plate, provided between the metallic rigid plate and the anchor mounting bracket mounting flanges, the membrane layer being bonded to the metallic rigid plate.

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.

A method includes providing a production line configured for continuous fabrication of polymer or predominantly polymer roofing boards by setting and expansion of precursor materials on a conveyor. A first polymer or predominantly polymer material foam precursor is dispensed to the production line, and allowed to rise and at least partially set to form a foam core layer for an insulation board, the foam core layer for the insulation board having a first density. A second polymer or predominantly polymer material foam precursor is dispensed to the production line and allowed to rise and set to form a core layer for a cover board, the foam core layer for the cover board having a second density greater than the first density. The combined thickness of the foam core layer for the insulation board and the core layer for the cover board is set by constraining the expansion of the combined foam precursors using a downstream forming conveyor disposed above the rising foam precursors.

A construction kit for producing coverings, particularly floor coverings, including components laid with their edges adjoining one another. According to the invention, the construction kit has components with at least one channel, particularly a groove open toward the support surface of the component, for receiving electric cables, and comprises a passage, connected to the channel and open toward the visible surface of the component, for laying the cables.

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 having three corners, the outside surface of each of the three side walls extending outwardly 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 channel pairs, each configured to receive a rebar, each channel pair including a first channel disposed on one of the three side walls on the inner surface and a second channel disposed on a corner of the three corners that is opposingly disposed from one of the three side walls.
