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 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 system for assembling structural insulated panels (SIPs) includes a set of splines that snugly insert into channels along the top, bottom and side edges of each SIP. Vertical alignment splines are used to align and connect adjacent SIPs and horizontal plate splines are used to cap edge channels of a SIP such that the edges of the SIP can securely rest on, support or be affixed to a foundation or other structural member. The system components facilitate fast and precise alignment, interconnection and installation of SIPs in order to form walls, floors, roofs or foundation systems.

The present invention discloses a cross-laminated timber (CLT) decorative panel and a connecting device thereof, and belongs to the field of construction materials. The CLT decorative panel includes a first decorative layer, a buffer layer, a CLT layer and a second decorative layer, where the first decorative layer, the buffer layer, the CLT layer and the second decorative layer are sequentially arranged from top to bottom, and the buffer layer is internally provided with a non-Newtonian fluid. The connecting device includes a support body and a connecting block arranged on the support body; the support body has a rectangular solid structure; a cross section of the support body is square with a side length the same as a thickness of the decorative panel; the connecting block is fit with the connecting groove.

Building or structural panels may be joined, such as to form walls or floors. The panels may be connected in various orientations via one or more connectors. The connectors may mount to anchors associated with the panels. The panels may have outer skins located over an expanded core comprising a matrix of supporting elongate members and voids or openings, with the anchors located at edges of the panels.
