A roof assembly can be attached to the wall frame in a stationary fashion or in a movable fashion to allow the roof to open, permitting access into the enclosure for servicing equipment housed therein. The enclosure has other features as described in the specification in further detail.

A modular panel is provided and includes a sill plate, a top plate, a plurality of vertical studs, and having at least one skin applied to a major face of the modular panel that presents a first edge having a waveform profile configured to connect to an opposing edge of an adjacent modular panel. At least one of the vertical studs is an end stud having a connector element configured to be secured to a complementing connector of the adjacent modular panel. Two or more of the modular panels may be connected together to form part of a shelter.

A shower enclosure comprises a plurality of prefabricated panels that are arranged to at least partially surround a space for bathing. At least one of the panels is a layered structure having a first layer, a second layer, and a third layer. The first layer forms an interior surface of the shower enclosure exposed to the space for bathing. The third layer is arranged between the first layer and the second layer, and is coupled to the first layer and the second layer. The layered structure is a sandwich structured composite comprising the first layer, second layer, and third layer.

A play center including a number of frames secured to each other to at least partially define substantially vertical walls of the outdoor play center, each frame having two or more openings, and a number of panels, each panel having a body thereof, the panels being receivable in selected ones of the openings. Each of the openings is partially defined by one or more elongate side walls of each frame. Each panel includes one or more flanges extending from the body over at least a receiving portion of the side wall. The play center also includes a number of fasteners for fastening the flanges to the receiving portions.

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.

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 wall system comprising at least one wall module and at least one linking element is provided. Said wall module comprising a substantially rectangular plate (3), said rectangular plate comprising two side edges (5a, 5b), each comprising a side edge bent configuration (11), wherein said side edge bent configuration comprises a first side bend (13a), a second side bend (13b) and a third side bend (13c), wherein all three side bends (13a,b,c) are substantially 180° or 160-200° and are provided along different bending lines being parallel with the side edges (5a, 5b) of the plate. Said linking element comprises an elongated rectangular plate (33; 33′) comprising two side parts (45a, 45b: 45a′, 45b′) along a length of said plate (33; 33′) and a middle part (47; 47′) along the length of said plate between said two side parts, wherein said two side parts (45a, 45b; 45a′, 45b′) comprises locking features (43a, 43b; 201; 43a′, 43b; 43a″; 43b″; 43a′″; 43b′″), wherein the radius of the second side bend (13b) of the wall module is provided such that a side part (45a, 45b; 45a′, 45b′) of the linking element (31; 31′; 31″; 31′″; 31″) can be provided into an opening (17) between first and third bent side parts (15a, 15c) of the wall module and during the connection will be passing a third bent side part (15c) which finally will lock a side part (45a, 45b; 45a′, 45b′) of the linking element (31; 31′; 31″; 31′″; 31′″) within the side edge bent configuration (11) of the wall module (1) when a wall module and a linking element have been connected.

A framing member forming a frame of a factory building is provided with a slit for attaching a holder on one side face of the framing member, the slit extending in a longitudinal direction of the framing member, the slit is provided with a detachment prevention mechanism configured to exert an action of preventing an insertion piece of the holder from being detached and to fix the holder to the framing member, along with an insertion of the insertion piece into the slit, and the holder is provided with a pinching piece configured to pinch an end edge portion of a wall panel between the pinching piece and the framing member to fix the wall panel to the framing member, along with the insertion of the insertion piece into the slit.
