The clamps used are typically magnetic or vacuum clamps for flat surfaces, chain or claw clamps for pipes and various mechanical clamps for welding onto I beams or other shapes. The weld is made by rotating the stud at high speed and forcing it onto the substrate causing friction which heats the stud tip and substrate surface.
The dimension of a wide-flange I-beam. In the United States, steel I-beams are commonly specified using the depth and weight of the beam. For example, a "W10x22" beam is approximately 10 in (254 mm) in depth with a nominal height of the I-beam from the outer face of one flange to the outer face of the other flange, and weighs 22 lb/ft (33 kg/m).
The lifting beam (also known as traverse, spreader beam) is a steel beam that is attached to the hook of the crane in order to spread the slings from one end of an elongated load (like a wall panel) to another. The bottom of the beam has multiple connection points for hanging the load. [1] H-shaped traverse. The lifting beams are used in ...
A table is built pretty much the same way as a beam formwork but the single parts of this system are connected together in a way that makes them transportable. The most common sheathing is plywood, but steel and fiberglass are used. The joists are either made from timber, engineered lumber (often in the form of I-beams), aluminium or steel. The ...
The farm jack also known as a railroad jack, high lift jack, handyman jack, trail jack or kanga-jack was invented in 1905. It consists of a steel beam with a series of equally spaced holes along its length, and a hand-operated mechanism which can be moved from one end of the beam to the other through the use of a pair of climbing pins.
Lifting design is influenced by the steel / concrete interaction of the specific anchor selected. Different load cases are considered by the lifting design engineer, such as anchor susceptibility to edge distance, placement sensitivity, and anchor capacity at the specific concrete strength at time of lift.
