The anchor selection, together with additional reinforcement, and rigging arrangements is influenced by: - The dead weight of the element - The number of anchors in the element and the configuration of the anchor - Capacity of the anchor at the specific concrete compressive strengths at time of lift - The dynamic loads applied during lifting ...
The insert can be a threaded rod. See also bolt (climbing). Anchor channels: used in precast concrete connections. [8] The channel can be a hot-rolled or a cold-formed steel shape in which a T-shape screw is placed in order to transfer the load to the base material.
In trad climbing belay stations, load-sharing anchors are often constructed from more than two individual anchors, which are rarely co-planar. In these cases, each individual anchor would feel a reduced force from the above values, but the best practice is to reduce the angle between the two outermost elements and avoid angles in excess of 120 ...
Uses include creating friction prusik knots for ascending or gripping fixed climbing ropes, usually using thinner approximately 5 to 6 mm (0.20 to 0.24 in) cord, or for attaching to, and equalizing forces across, multiple fixed anchors points, [15] such as when setting up abseil or belay anchors on multi-pitch climbing routes, usually using ...
anchor bolt: A special type of bolt that is set into concrete, with screw threads protruding above the concrete surface to accept a nut. breakaway bolt: A breakaway bolt is a bolt with a hollow threaded shank, which is designed to break away upon impact. Typically used to fasten fire hydrants, so they will break away when hit by a car. Also ...
An ice screw. Some modern screws like this one now have a handle to assist entry and removal, whereas early models did not. An ice screw is a threaded tubular screw used as a running belay or anchor by climbers on steep ice surface such as steep waterfall ice or alpine ice during ice climbing or crevasse rescue, to hold the climber in the event of a fall, and at belays as anchor points.

A set of barrels can be used with a mono-strand stressed tendon as an alternative to an anchor block. block See anchor block. bond The adhesion of concrete or grout to prestressing strands, wires or bars, or to unstressed reinforcement, either through friction or mechanical interlock.
