A structural panel for building construction includes a series of truss members, and accompanying sinusoidal support elements in welded communication and enclosed in a planarly extended foam layer. Together, the structural panel allows for easy and efficient off-site assembly, which creates a lightweight panel with an increased weight-bearing capacity using inexpensive and versatile materials.

A modular wall system for use in trade shows includes a wall or header panel formed of frame parts, and a connecting bracket for detachably connecting the end of the panel to an upstanding column. Perpendicular sections of a corner connector are received in the hollow end of different ones of the frame parts to connect the frame parts. A fabric cover defines a recess with an open end adapted to receive the frame parts. A closure device is provided for at least partially closing the open end of the fabric cover. A vertical support member extends from the frame parts to a surface to transmit the weight of an accessory to the surface. The accessory may be an adjustable garment rack, a coupling grid, a shelving unit, or a peg-board unit and a hook. The system includes a crate adapted to receive a plurality of members for transport.

A dismantlable anechoic chamber for sound attenuation includes a number of interconnected panels. The panels have a groove around their edges. The spaces produced by the corresponding grooves at contacting edges of adjacent panels are occupied by battens. The panels have a sandwich-type structure, in which a layer of sound-attenuating material is positioned between the two main faces of the panel. There is dimensional interference between the battens and the panels. The chamber has, on its internal face, an additional sound-attenuating layer. This sound-attenuating material is a foam-like material. The batten has an intermediate layer of sound-attenuating foam material.

The invention comprises building panel assemblies for use in the construction of new homes, commercial buildings and extensions of one or more storeys. There is provided a rectangular structural insulated panel (SIP) (10), which comprises a pair of spaced-apart containment boards (12, 12) an inner insulating core (13) and a low profile peripheral external rigid frame (14), preferably of metal, e.g. steel, extending around the entire periphery of the spaced-apart boards (12, 12), the insulating core (13) having spaced-apart slots (16), which also extend around the entire periphery of the panel.

A process for fabricating a unitized structure comprises creating a multilayer structure by applying a flame-retardant resin to a first layer and stacking, on the first layer, an intermediate layer comprising a honeycomb structure. Further, a second layer is stacked on the intermediate layer and the flame-retardant resin is applied to the second layer. The multilayer structure is then heated to a desired temperature and a pressure is applied about the multilayer structure for a predetermined process time. Moreover, the flame-retardant resin is prevented from entering spaces of the honeycomb structure. After elapse of the predetermined process time, the pressure is released, creating the unitized structure.

Disclosed is a furniture connecting and fixing device which allows pieces of furniture or partitions to be connected or separated without using an additional tool and which makes pieces of furniture to be firmly connected even upon an external force. The furniture connecting and fixing device includes: a female body having a female magnetic plate fixed and embedded therein; a male magnetic plate magnetically attached to the female magnetic plate; a male body having the male magnetic plate embedded therein in a manner such that a part of the male magnetic plate is able to enter and exit from the male body; and a magnetic space which is formed inside the female body and into which a part of the male magnetic plate protruding from the male body due to a magnetic force is inserted to be magnetically attached to the female magnetic plate.

A wood-concrete composite slab having a planar wood element, by means of which spans with little dependence upon the relative inherent weight of the slab are achieved. The slab layer construction includes a wood layer, an insulating layer, and a concrete layer. In one embodiment, the layer construction is interrupted by at least one bearing means, in that this bearing means traverses at least the concrete layer and the insulating layer and extends downward at least as far as the wood layer. In a different embodiment, for a high level of soundproofing, the slab comprises in its insulating layer two different-density insulating materials, wherein the denser insulating material rests directly on the wood layer, acting as a vibration damping means. In a further embodiment, the wooden panels of the wood-concrete composite slab that form the planar wood element are tensioned against one another in order to convey tensile forces therethrough.

Modular building methods and systems using precision machined modular panels. Standard modular panels are used for constructing walls, floor, and roof, with transitions from wall to roof and wall to floor provided by special transition panels. The standard panels include a channel formed configured to receive a flange of a C-channel member. The present method progresses by installation of a foam panel (or stack or row of such panels), followed by installation of a C-channel member, with the flange of such member engaged in the panels, followed by installation of an adjacent row or stack of panels, before installation of the next, adjacent C-channel member. Such alternating placement of panels and frame members eliminates the need for a tape measure, the need for any independent frame for the building, and ensures the walls, floor, and roof are square and plumb, as the precision machined panels ensure these requirements are met.

Implementations of the present invention relate to systems, methods, and apparatus for constructing a building. More specifically, the present disclosure provides an interlocking wall system that can allow a builder to accurately position, orient, and/or secure various structural wall modules. Additionally, this disclosure provides systems and methods for securing one or more cladding layers to the building's envelope. Furthermore, implementations of the present disclosure can allow for quick and modifiable installation of utility and communication lines within the building.

Building techniques and structures to fabricate components of expanded polystyrene (EPS) for assembly into a building include structures and ways to make keys to provide shear strength between components, structures and ways to minimize infiltration paths between walls and floors and walls and roof while reducing labor, material wastage and logistics complications. By way of example, components are strategically cut from a block of EPS using a hot wire moving through the block to cut components to a desired and novel configuration.
