Expandable surfaces made from sheet materials with slits distributed on the surface of sheet material where the surfaces expand by application of force along or / and across the surface of sheet material. The unexpanded surfaces are flat sheets, or closed surfaces like cylinders, spheres, tubes, or custom-designed organic shapes marked with pre-formed or post-formed slit designs. The expanded surfaces can be single units or modules which can be attached to one another through various means. The sheet materials range from hard surfaces like metals, to softer materials like papers and plastics, or pliable materials like fabrics, rubbers, synthetic surfaces or bio-surfaces. The slits are arranged in patterns ranging from periodic, non-periodic to irregular designs. The slits can be straight, bent, curved or irregularly shaped with even or uneven spacing. Slitting can be achieved by digital cutting or punching devices like laser-cutting, water-jet cutting, digital punching, automated dies, etc. or pre-formed when casting the sheet material. Force can be applied manually with tools or through the use of machines and special set-ups. Applications range from architectural surfaces, walls, ceilings, panel systems, structures and sculpture. On a smaller scale, applications include containers, packaging material, fabrics and human wear. On micro- to nano-scale, applications range from expandable surfaces for gauzes, band-aids, stent designs, skin grafts, semi-permeable membranes and micro-filters for various industries including purification of fluids and chemical substances.

A composite construction panel having a thin panel of concrete material and a reinforcing grid of sheet metal studs with embedment portions which are actually embedded into the concrete panel, each of the studs having a web, main web openings through the web, a right angular flange formed on a free edge of the web, an embedment angled flange portion formed along the opposite edge of the web, an edge strip formed on the angled flange at an angle thereto; and, spaced apart angled flange openings formed in the angled flange for flow of concrete therethrough. An alternate form of stud has a triangular tube structure along one edge of the web. Another form of stud has a discontinuous webs defining spaces between them. In one embodiment two concrete panels may be secured to the studs in spaced relation to create a hollow structure.

A plurality of studs (14) are spaced apart relative to each other. Upper end portions (32) of the studs fit into an upper channel space (22) and lower end portions (34) fit into a lower channel space (30). The lower channel space (30) is defined in part by a pair of spaced apart sidewalls (24, 26). Screw fasteners (52) extend through the sidewalls (24, 26) and connect them to the lower end portion (34) of the stud (14). The studs (14) have upper ends that are spaced from a web (20) forming the upper boundary of the upper channel space (22). Vertical elongated slots (48, 50) are provided in the sidewalls (38, 40) of the studs (14). Screw fasteners extend through the sidewalls (16, 18) of the upper channel member (10) and then extend into and through the slots (48, 50). The heads of the screw fasteners (52) bear against the sidewalls (16, 18) when the screw fasteners (52) are tightened. This firmly connects the screw fasteners (52) to the sidewalls (16, 18), but there is no connection of the screw fasteners (52) to the upper end portions of the studs (14). When the screw fasteners (52) are tightened, there is no clamping action between the heads (54) of the screw fasteners (52) and the upper end portions (32) of the studs (14). As a result, the studs (14) are completely free to move up and down relative to the upper channel member (10), within limits established by the lengths of the slots (48, 50).

Slotted header tracks for exterior wall applications. In exterior wall framing, the exterior wall sheathing is required to have a horizontal gap at or near the floor line for anticipated vertical movement between the floors. To accommodate orthogonal movement of the studs relative to the track, a plurality of slots are located along the flanges of the header track. An area for exterior sheathing attachment is created by leaving the upper portion of the flange solid for sheathing attachment and providing slots on the lower portion of the flange. Embodiments may include elongate reinforcing grooves on the slotted track's flanges and / or web, tabs for supporting and positioning exterior sheathing elements, connector elements for connecting the track to another surface, and second slots along the length of the web of the track to allow for limited drift movement of the track.

The present application is directed toward slotted tracks, in particular slotted tracks for an exterior wall application. Embodiments can include tracks with elongate reinforcing ribs on the tracks' flanges and / or web, tabs and / or protruding ribs for supporting and positioning exterior sheathing elements, second slot patterns along the length of the web of the track to allow for attachment and drift movement of the track with another wall component, and guide marks to identify proper locations for attachment of fasteners.
