The present invention relates to a structural joint for attaching two boards by their butts, achieving the correct transmission of forces between them by means of a staggered configuration of the butts thereof to increase the contact surface between both boards, allowing the mutual coupling thereof, both being aligned and coplanar, and at least one of the steps of both boards having a finger profile to further increase the contact surface between both boards.

A handheld mortise forming device includes a base unit having a first support extending parallel to a first axis. The first support includes first and second working ends. A first sidewall and a second sidewall are connected to the first support. One of two connecting units is rotatably mounted to the first sidewall. The other connecting unit is rotatably mounted to the second sidewall. A second support extends parallel to the first axis and is connected to the two connecting units. The second support is rotatable relative to the first and second sidewalls and includes an abutting face. A clamping unit includes a pressing member located on a side of the second support adjacent to the abutting face. The pressing member can clamp lumber. The pressing member is jointly rotatable with the second support and is switchable between the first working end and the second working end.

Building panels, especially laminated floor panels are shown, which are provided with a locking system and several core grooves at the rear side in order to save material and decrease weight. Building panels, each having a surface layer on a front side, a backing layer on a rear side and an intermediate core, wherein the intermediate core and the surface and the backing layer all comprise wood fibres and thermosetting resins, the building panels are provided with a locking system for vertical and horizontal locking of a first edge of a first building panel to an adjacent second edge of a second building panel.

Structural systems having coated structural members with enhanced durability are provided, along with methods of making and using the same. Structural members including at least one coating material applied to a substrate that comprises at least one protrusion may exhibit increased strength and/or durability and may be less likely fail during use. For example, structural members as described herein exhibit an improved resistance to cracking when a force is applied to the protrusion. Structural systems according to embodiments of the present invention can be suitable for use in a variety of applications, including in ready-to-assemble furniture or cabinetry applications or as building and construction materials such as wall board, flooring, trim, and the like.
