A connector for interconnecting two building members together. The connector, in one embodiment, includes first and second plates secured together. Each plate includes one or more elongated slots wherein the elongated slots of one plate are oriented at an angle of approximately 90° with respect to the slots formed in the other plate. Fasteners extend through the slots in the plates and connect the plates of the connector to two building members such as a horizontal building member and a vertical building member. Once connected, one of the building members is free to move with respect to the other building member while the connector is connected to the two building members. In another embodiment, the connector is slidable within a track. In this embodiment, a portion of the connector extends from the track and connects to one of the building members while the track connects to the other one of the building members.

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 light steel structural member includes a web portion and a pair of flanges. The web portion has a web face. The pair of flange portions each extend generally orthogonally from each end of the web portion. The flange portions each having a plane and the planes are generally parallel each other and each flange has a flange face. At least one of the web face and the flange face has a plurality of embosses formed therein. In another embodiment the light steel structural member further includes a pair of restraining ribs. In a further embodiment the light steel structural member further includes a pair of lips and a pair of multi-cranked stiffeners. A method of making the light steel structural members is shown.

An apparatus for attaching a building component to a structure. The apparatus may include a C-shaped support header that is sized to be received on a portion of a structure such as the top plate of a wall. A number of attachment tab assemblies are integrally formed in the support header and protrude therefrom to facilitate attachment of the building components to the support header.

The invention relates to a strip for a building board (2), exhibiting a board body (S) which is formed with a gripping stud (24). The strip (10) extends from the body (S) and from which are formed gripping elements (26, 28), which are bent round the gripping stud (24) for mechanical fastening of the strip (10) to the body (S), as well as a locking element (12) for enabling mechanical joining of the board (2) to similar boards.

A fastener for joining two pieces of rebar together in a rebar grid used to reinforce subsequently poured concrete is described. The fasteners include two clamp pieces that in certain embodiments completely wrap around a piece of rebar and are tightly secured thereto. Further, each clamp piece can swivel or rotate up to 360 degrees relative to the other clamp piece such that two rebar pieces intersecting at any angle can be coupled together.

A building roof tie for attaching roof trusses and rafters to wood top plates in building structures, such roof tie having a sheet metal body with risers and a bridge for overlapping a rafter and flaps for wrapping on the sides of the top plate. Generally triangular shaped reinforcing wings provide strength and stability, allowing the roof tie to be manufactured from different weights of steel. The roof ties are pitched to conform to a variety of framing applications. A plurality of apertures is formed in the roof tie to provide openings for fasteners for connecting the tie to the wood top plate and rafter.

The invention comprises connector for a pair of opposed spaced concrete forming panels. The connector comprises an elongate spacer member having flanges formed thereon intermediate a central portion thereof and each opposite end thereof. A portion of at least one end of the spacer member is sized and shaped to selectively engage an elongate panel bracing member. A composite insulated concrete form and a method of using the insulated concrete form are also disclosed.
