Wall-building element system comprising sole elements, basic wall-building elements adapted to be assembled to a wall, and beams adapted to be fitted between each horizontal layer of the basic wall-building elements. The basic wall-building elements are prefabricated with a central, load bearing core member and form-stable layers of thermal insulation on both sides thereof. The core member and the thermal insulation layers are mutually adapted in a tongue-and-groove system while the beams are made in an “H”-profile corresponding thereto. The core member typically consists of a plate-shaped main body provided with laterally extending, vertically oriented ribs.

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.

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.

A modular construction system, including, first and second walls, each having first and second broad surfaces. Each wall includes throughgoing connector-receiving bores. The modular construction system further includes a connector including a longitudinal body portion arranged along a longitudinal axis and having a first width. A head portion of the longitudinal body portion includes a base surface having a second width in a direction transverse to the longitudinal axis. A pair of protrusions extend outwardly from the longitudinal body portion and are disposed between the base surface and a tail end of the longitudinal body portion. The protrusions include an engagement surface facing toward the base surface and having a third width, the third width being greater than the first width.

A method of construction of composite wall module system in which a first wall module and a second wall module are coupled to the first wall module by a vertical joint. The vertical joint is comprised of plurality of anchors and reinforcement bars as well as steel side plates allowing composite wall steel faceplates to be discontinuous across the vertical joint. The faceplates of the first and second modules are not made continuous across the vertical joint through continuous welding. The vertical wall joint further includes fill disposed between faceplates and side plates adjacent to anchors and reinforcement bars.

A composite wall panel having a front surface, a rear surface, and side surfaces extending therebetween is provided. The panel includes a cured composition of pieces of cellulose and/or chaff and at least one binder. A wall assembly is also provided. The assembly includes: a frame including a plurality of linearly arranged elongated studs having a top end, a bottom end, and a first longitudinal side and a second longitudinal side extending between the respective ends; a plurality of interconnected wall panels mounted to the first side of the elongated studs of the frame to form a first wall portion; a plurality of interconnected panels mounted to the second side of the elongated studs to form a second wall portion; and an insulating layer inserted within a cavity between the first wall portion and the second wall portion.

A building construction system (2) for construction of a building (20) is disclosed. The building construction system (2) comprises a plurality of modules (M.sub.1, M.sub.2, M.sub.3, M.sub.4, M.sub.5, M.sub.6, M.sub.7, M.sub.8, M.sub.9, M.sub.10, M.sub.11), each comprising at least one centrally arranged insulation member (4, 4) sandwiched between a first cover plate (12, 12) and a second cover plate (14, 14). The at least one insulation member (4, 4) is made in polyurethane (PUR) or polyisocyanurate (PIR). A reinforcement connection structure (10) extends between and is mechanically connected to opposite cover plates (12, 12, 14, 14). At least a portion of the joints (6, 6) between adjacent cover plates (12, 12, 14, 14) are glued together.

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 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.
