A joint for a shower enclosure includes a first end member, having a first flange, a rearwardly extending segment spaced apart from the first flange, and a rearwardly open recess defined between the first flange and the rearwardly extending segment. The joint further includes a second end member, having a second flange, a forwardly extending segment spaced apart from the second flange, and a forwardly open recess defined between the second flange and the forwardly extending segment. A gap is defined between the rearwardly extending segment and the second flange when the first end member and the second end member are coupled. The forwardly open recess is configured to receive the rearwardly extending segment and the rearwardly open recess is configured to receive the forwardly extending segment.

A method for forming three-dimensional (3D) printed structures is disclosed. The method may include 3D printing a first structural member including an opening to a cavity inside the first structural member; and 3D printing a second structural member including a protrusion disposed within the opening and the cavity of the first structural member.

A joining system is provided for connecting first and second building construction members. The system includes a female dog (18) that connects to the first building construction member (14) and includes first and second female dog receiving surfaces (20,22), which face generally away from each other, and are adjacent an aperture (24) defining an axis. The system further includes a male dog (32) that is connectable to the second building construction member (16) and includes first and second male dog clamping surfaces (33,34) which generally face each other. The male dog (32) inserts through the aperture (24) and moves in a first lateral direction to clamp the female dog (18). A locking arrangement (42) includes first and second locking structures (44,46) which engage to permit movement of the male dog (32) in the first lateral direction to increase a clamping force on the female dog (18), and inhibit movement opposite the first lateral direction.

Panels are shown which are provided with a mechanical locking system allowing perpendicular connection with a snap action. A set of panels including a first and a second panel, an edge of the second panel is insertable into a groove of the first panel, when the panels are arranged essential perpendicular to each other, to obtain a mechanical connection between the first and the second panel, when the second panel is displaced essentially perpendicularly to the first panel.

A set of panels including a panel with a first main plane and an adjacent panel with a second main plane, wherein the panel and the adjacent panel are provided with an angleable locking device for locking a first edge of the panel to a second edge of the adjacent panel. The first main plane is essentially perpendicular to the second main plane. The angleable locking device includes an edge groove at the first edge and a tongue groove at the second edge. The edge groove includes a flexible tongue arranged in an insertion groove at a first side of the edge groove. The angleable locking device is configured to be unlocked by an angling motion of the panel relative the adjacent panel, such that an angle between the first and the second main plane increases.

A hybrid structural member for an insulated structural panel includes a core member surrounded on at least two sides by a high-density structural foam. The hybrid structural member may be manufactured by placing a core member in a cavity of an injection mold and surrounding the core member by insulating foam on at least two sides. The core member may be held in place by screws, posts, pins, a vacuum, or other suitable means.

A module splicing structure comprises to-be-spliced modules (C), a connecting component (A), a reinforcing accessory (B), and functional accessories (D, E, G). The to-be-spliced modules (C) are provided with holes or troughs. The connecting component (A) is inserted into the holes or the troughs of two adjacent to-be-spliced modules (C). The shape of the whole or partial cross section of the connecting component (A) inserted into the to-be-spliced modules (C) is the same as the shape of the cross sections of the holes or the troughs of the to-be-spliced modules (C). Connected by the connecting component (A), multiple to-be-spliced modules (C) are spliced into a whole structure or a building. The structure is applied to the field of engineering construction, and can be assembled, disassembled and maintained conveniently and quickly.
