A building module which is a sandwich panel comprising a first region which provides part of the roof structure of a building, a second region which provides part of the wall structure of the building, and a third region which provides part of the floor structure of the building.

A modular shelter structure is an apparatus that provides readily available housing for a variety of environments. The apparatus includes a shelter, a plurality of first locking mechanisms, and a plurality of second locking mechanisms. The shelter includes a floor base, a plurality of portable walls, and at least one roof panel. The floor base balances the shelter across various terrains. The plurality of portable walls surrounds the floor base and defines an interior environment with the floor base. The interior environment is enclosed with the at least one roof panel. The plurality of portable walls is attached onto the floor base with the plurality of first locking mechanisms. Similarly, the plurality of portable walls is attached onto the roof panel with the plurality of second locking mechanisms. The plurality of first locking mechanisms and the plurality of second locking mechanisms each include an inner tube and an outer sleeve.

The present invention provides a panel sheathing for making wall and roof structures in which the panels (e.g., wood boards, oriented strand boards, plywood, etc.) are pre-coated at a factory, before installation at the building/construction site, using a polymeric barrier coating having specific water permeability, self-sealing properties with respect to penetrated metal fasteners (e.g., nails) in accordance with ASTM D7349 (modified using 1.5-5.0 inches water depth in hydrostatic head testing over sample of coated panel in which a steel nail is driven to within ⅛ inches of being flush with the panel and conditioning the test specimen for 24 hours at 23° C. prior to hydrostatic loading), as well as anti-blocking properties whereby the coated panels can be transported in stacked configuration without sticking or disintegration of the polymeric barrier coating. The coated panels do not require the use at the installation site of felt paper, house wrap, or additional applied barrier coating to provide excellent weather barrier properties. The present invention also provides methods for constructing the panel sheathing structure as well as for making the coated panels.

This invention relates to a demountable cassette construction system for building a structure comprising one or more demountable cassettes, wherein the or each of the one or more demountable cassettes are attachable to one or more adjacent demountable cassettes via demountable joints, wherein the demountable joints permit the one or more demountable cassettes to be removed from a structure without removal of and/or damage to the or each of the one or more adjacent demountable cassettes.

Insulated, load bearing wall panels are machined from a raw foam slab of foam material. The raw foam slab is loaded into a Turcotte sculptor. The Turcotte sculptor is an elegant 36-axis machine that machines the raw foam slab into one or more insulated foam wall panels. The Turcotte sculptor, in particular, may accept very large 18x4x2 feet slabs of foam material. The Turcotte sculptor then individually commands and actuates any of 36 linear actuators to produce the one or more insulated foam wall panels. The Turcotte sculptor, within minutes, simultaneously machines the raw 18x4x2 foam slab into two (2) 9-feet tall wall panels for 9-feet ceilings. The Turcotte sculptor may easily machine other wall sizes. The Turcotte sculptor thus efficiently and quickly volume produces entire one-piece, single-height insulated wall panels at reduced cost and with outstanding energy performance.

A concrete slab (20) comprises conventional concrete and a combined reinforcement of both post-tension steel strands (22, 26) and fibres (29). The post-tension steel strands (22, 26): —have a diameter ranging from 5 mm to 20 mm, —have a tensile strength higher than 1700 MPa. The fibres (29) are present in a dosage ranging from 10 kg/m.sup.3 to 40 kg/m.sup.3 in case of steel fibres are in a dosage ranging from 1.5 kg/m.sup.3 to 9 kg/m.sup.3 in case of macro-synthetic fibres.

The invention relates to a panel and a method for producing a panel. The panel is in particular a floor, wall or ceiling panel, and comprises at least one core layer, the core layer comprising an upper core surface and a lower core surface and at least one pair of opposite side edges; wherein the core layer comprises magnesium oxide cement; wherein the core has a density which is substantially homogenous over its entire volume, and wherein at least one decorative top layer is attached to an upper core surface of the core layer.

Insulated wall and roof sheathing systems for use in building construction designed to provide moisture permeable wall panels that protect from bulk water, excess air, and thermal transfer.

The present invention is directed to a multi-purpose panel member which may be utilized as any surface or support beam in a structure. In a preferred embodiment, the panel may be extruded monolithically from aluminum. Also disclosed are systems for assembling structures from the panels utilizing a plurality of other components, which are also preferably extruded from aluminum.

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.
