At least one of the major surfaces is laminated to a surface of a second member.

A method of manufacturing a structural panel for building construction, comprising: subjecting timber feedstock to machine stress grading wherein individual timber sticks that satisfy the grading criteria are allocated a stress grade for structural use; selecting from the timber sticks that fail to satisfy the machine stress grading standard criteria, laminas for forming a panel; arranging the selected timber laminas, without regard to visual defects, in side-by-side parallel formation; and fabricating a structural panel wherein the selected timber laminas are arranged side-by-side parallel to one another with adhesive applied between each adjacent stick incorporated into the panel.

A torsion box panel assembly includes a plurality of sub-panels each having a skin secured to a core, and a plurality of hinges each coupled between a different pair of the sub-panels such that each sub-panel is foldable relative to an adjacent sub-panel along a respective hinge. The hingedly-coupled sub-panels together form a base panel having an expanded configuration in which each hinge is closed and the surfaces of the sub-panel skins are substantially co-planar. The base panel, in its expanded configuration, has a planar panel surface defined, at least in part, by the combination of the co-planar sub-panel skins. At least one stabilizing member is secured to the planar panel surface and spans all of the closed hinges to lock the sub-panels together to form a torsion box panel.

High-frequency hot-pressing continuous automatic production lines for dimensional bamboo timbers, and production methods thereof are provided. The production line can include a clip-up store and feeding mechanism fixed with one end of a three-roller type gluing system. An other end of the three-roller type gluing system is fixed with one end of a system for loading, layer up and stacking non-glued bamboo sheets. The outer side edge of the system for loading, layer up and stacking non-glued bamboo sheets is connected to a front inner end of a plate stack conveying system. A high-frequency press and high-frequency generator system is located at a rear inner end of the system for loading, layer up and stacking non-glued bamboo sheets.

The present invention discloses a one-step integrally-formed bamboo sleeper. For the one-step integrally-formed bamboo sleeper, a bamboo unit is used as a raw material, to be dried and modified at the temperature of 110-180° C., and then subject to adhesive dipping, adhesive throwing, solidification, dopamine solution treatment, anti-mildew and/or anti-corrosion and/or anti-insect treatment, and fastening, to obtain the one-step integrally-formed bamboo sleeper with a density of 0.9-1.5 g/cm.sup.3. The present invention further provides a preparation method for the foregoing bamboo sleeper. The bamboo sleeper prepared in the present invention has a suitable elastic modulus, and applicable for ballasted tracks of railways and urban rail transit systems.

A fitting attachable to a cross-laminated panel provides a chase, plumbing space, airflow duct, or wiring route on an edge of the cross-laminated panel. The fitting may run between edges of multiple cross-laminated panels that contain integral hollow members, forming a customizable network of contiguous coplanar routing paths, accessible without installing pipes and wires behind, or in front of the cross-laminated panels. The fitting may also provide a vertical chase for single or multiple cross-laminated panels. The fitting takes advantage of one or more hollow members in the cross-laminated panels to provide contiguous routing paths for wires, pipes, and venting within the cross-laminated panels themselves, extending across any layout of multiple cross-laminated panels. The fitting may additionally serve as mechanical support for attachment of adjacent panels. Further, the fitting may provide structural connection for the CLT panels as required to meet structural code requirements for the building.

A wood laminated construction element includes a wooden surface piece and a wooden bonded body. The wooden surface piece has a natural wood grain in a first wood grain direction, and includes two end segments and a connection segment disposed between the end segments. The wooden bonded body includes at least an end wood piece and at least a connection wood piece. The end wood piece is adhered to one of the end segments, and has a natural wood grain in a second wood grain direction transverse to the first wood grain direction. The connection wood piece is adhered at least to the connection segment, and has a natural wood grain in a third wood grain direction which is consistent with the first wood grain direction.

The invention relates to a simple and safe method for manufacturing a wood part joint, in particular a cross-laminated timber for a house wall, from a plurality of individual layers which are laid as longitudinal layers (L) and transverse layers (Q) at an angle to one another and subsequently joined, preferably glued and pressed, at their mutually facing main surfaces. According to the invention, at least the boards of the longitudinal layer (L) are pre-fixed in their transverse direction using an elongate string element (2) at least in the end region, in particular using beading pressed into a groove. The invention also relates to a corresponding device for carrying out the method, wherein a feed for the elongate string element (2) is provided which can independently also be used for a wood part joint in which abutting, shorter pieces of wood are pre-fixed in the longitudinal direction to a board.
