A profile assembly produced from a first profile and a second profile connected longitudinally by cold joining. Both profiles bear complementary clamping structures on long sides thereof facing toward one another for cold joining together. The clamping structure of the first profile comprises a clamping head formed on a web and forming an undercut on each side of the web by way of a greater extension in the profile transverse direction in relation to that of the web. The clamping structure of the second profile comprises a clamping head receptacle for accommodating a section of the clamping head and a clinching leg, formed on a profile-exterior leg of the clamping head receptacle, having a first profile arm protruding before cold joining and a second profile arm formed at an angle thereon, the free end of which engages behind the clamping head and, before cold joining, faces toward a clamping pocket of the first profile. The clamping head receptacle is tapered with respect to its open width and/or the clamping head is tapered with respect to its material thickness of the section to be inserted into the clamping head receptacle, wherein the section of the clamping head pressed into the clamping head receptacle is connected to the clamping head receptacle in a metallically sealed manner.

A modular building system, includes a modular building assembly, including a base mounting structure with first and second base angle brackets; a left receiving wall assembly, including a left primary wall assembly, and left front and left rear corner brackets; a right primary wall assembly, and right front and right rear corner brackets; and front and rear wall assemblies; and a platform with legs; such that the modular building assembly is positionable on a top surface of the platform.

This application relates to the field of reveal architectural panels and a tool or clamp for assembly thereof. The apparatus and method replace prior art assembly methods and fasteners with adhesives and a dedicated particularly designed clamp to facilitate assembly. The frame members are modified to facilitate assembly with adhesive sealants and removal of mechanical fasteners.

Building panels provided with a locking system for vertical and horizontal locking of a first edge and a second edge of adjacent panels. The locking system includes a displaceable tongue at least partly arranged in a displacement groove, a tongue groove, a cavity provided in a strip at the first edge, and a protrusion extending downwards at the second edge. The displaceable tongue is arranged to be displaced at least partly into the tongue groove during locking, and wherein the protrusion is arranged to be located in least a portion of the cavity when the panels are locked vertically and horizontally.

A stiff wall panel assembly includes a wall panel including a single, continuous, and unitary layer including a central portion having a plurality of central portion ribs spaced therealong, a first wall track engaged with the central portion and having a plurality of first ribs spaced therealong, and a second wall track engaged with the central portion and having a plurality of second ribs spaced therealong. Studs are engaged with the central portion, the first wall track, and the second wall track. Such studs have a plurality of third ribs each engaged with the central portion ribs, the first ribs, and the second ribs. The first ribs and the second ribs each are linearly interlocked as well as linearly and slidably interfitted within the third ribs of the studs. The first ribs and the second ribs each are parallel to the third ribs of the studs.
