A fastening system for joining a first structural member end-on to a second structural member is provided. The fastening system includes a latching device comprising at least one eccentric rotatable part and at least one generally S shaped latch spring hook joined to the rotatable part, and a receiver having at least one hole configured to receive a free end of the latch spring hook. The latching device is fixed to an end of a first structural member and the receiver is fixed to a side of a second structural member. The first structural member may be joined end-on to the second structural member by positioning the latching device on the first structural member adjacent to the receiver of the second structural member and rotating the rotatable part to cause the free end of the latch spring hook to engage the hole in the receiver. Further rotation of the eccentric rotatable part causes the latch spring hook to exert a pulling force, thereby joining the structural members together.

A barrier system for partitioning a space is formed by panels which interlock with each other to provide a barrier that is fire rated. The interlocking panels are assembled in the barrier in columns which include at least two panels. A first horizontal joint between two panels of the barrier in a first column is vertically offset from a horizontal joint between two panels of the barrier in a second column that is adjacent to the first column at a vertical joint. Each panel is made of a laminated structure including a supporting frame around a core layer, barrier layers on opposed surfaces of the core and skin layers on the barrier layers. Tongue and groove construction interlocks the panels and a locking structure formed by a tapered hook in the groove engaging into a slot of the tongue locks horizontally adjacent panels to each other.

A connector configured to couple plural wall elements like wall panels, the connector including a coupling including a first support that supports a locking hook that is pivotable from an idle position into an engagement position and movable into an interlocking position; a block including a locking bar that is arranged in a second support wherein the locking hook reaches behind the locking bar in the locking position; and a housing for the coupling or the block, the housing including a housing pass through opening wherein the locking hook passes through the housing pass through opening during a pivot movement from the idle position to the engagement position, wherein the housing includes a first housing half and a second housing half, wherein the housing pass through opening is closed by a cover wall against a pass through of the locking hook.

A structural panel system formed from a substrate (such as cement board or paper) and structural metal studs (such as lightweight galvanized steel members), where the metal studs are embedded within an insulating core that is formed onto the substrate, where the metal studs are gapped from the inner surface of the substrate to prevent thermal energy from transferring from the substrate to the metal stud or vice versa. In addition, parallel assembly slots may be formed in the gap at the top and bottom ends of each panel assembly to provide connective access to the top and bottom ends of the metal studs for structural connection to the foundation at the bottom or other overhead structure at the top via connective components. The connective components include a bottom U-channel member and a top U-channel member that are configured to fit into the parallel assembly slots.

Pre-fabricated wall panels with embedded electronic devices. Also, a modular building made from pre-fabricated panels with embedded electronic devices, individual panel identifiers, and a central computer system.

A field-deployable construction set for the assembly of a Relocatable Habitat Unit (RHU), used for simulating real world environments without costly construction expenses. The various panels, supports, and accessories used to construct an RHU include male (M) and female (F) lock connectors located on their respective peripheries and a frame constructed from a plurality vertical corner posts and horizontal beams provide the user with innumerable options for floor plans and building design, further providing significant options for reconfiguration of floor, ceiling, and wall panels without having to disassemble the structure. The exterior composition of the expanded polymer foam is customizable to provide a realistic environment for high quality training in a versatile system that is deployable by truck or aircraft and can be assembled with only a single tool.

A structural insulated building unit is provided for constructing a building. The structural insulated building unit includes an insulating core, first and second cementitious panels, and a connecting portion. The insulating core is defined by multiple sides and opposing first and second faces. The first and second cementitious panels are coupled to the first and second faces of the insulating core. The connecting portion is provided on one of the sides of the insulating core, and aligns the structural insulated building unit with an adjacent structural insulated building unit having a complementary connecting portion when constructing a building.

An enclosure for use as a walk-in freezer or refrigerator includes a first panel and a second panel connected to the first panel. Each of the first and second panels includes a body having a frame coupled to the body. The frame includes a beam of a first material and a jacket of a second material at least partially enclosing the beam. An interior edge of the frame is adjacent to the body. An exterior edge is defined by the jacket and defines a joint member. The joint member of the first panel defines a groove, and the joint member of the second panel defines a protrusion adapted to engage the groove of the joint member of the first panel. At least one joint member includes a deformable portion that compresses when the joint member of the first panel engages with the joint member of the second panel.

A cam lock for side-by-side tongue-and-groove interlocking panels can be arranged to work easily and effectively by using a keyed cam lock that provides proper orientation and a stop when the lock is engaged. A cam lock for side-by-side tongue-and-groove interlocking panels can be arranged to be inserted on the tongue side and act against a mid-portion of the opposed panel. An insert bracket can cover with one end at least a part of an end of a panel at a corner connection between panels and with the other end it can fit into a slot in the panel to immobilize the panel in two directions, while a fastener-receiving portion of the bracket can have a V-shaped portion whose side walls can guide the fastener to pass through the bracket at a bottom of the V-shaped portion. This concept applies for wall to wall connection, wall to ceiling connection and wall to floor connection.
