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 ...
This may be required to allow the correct seating for a countersunk-head screw or to provide the lead in for a second machining operation such as tapping. Countersink cutters are manufactured with six common angles, which are 60°, 82°, 90°, 100°, 110°, or 120°, with the two most common of those being 82° and 90°.
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. [1]: 9 bond strength The resistance to separation of hardened concrete or grout from prestressing strands, wires or bars, or from unstressed reinforcement.
Such anchors typically comprise tendons of high-tensile bundled steel strands or individual threaded bars. A tendon is grouted to the concrete or rock at its far (internal) end and has a significant de-bonded free length at its external end which allows the tendon to stretch during tensioning. Tendons may be full-length-bonded to the ...
In this case, concrete base material might be undamaged. Pull-out: the anchor is pulled out from the drilled hole partially damaging the surrounding concrete. When the concrete is damaged the failure is also indicated as pull-through. Concrete cone: after reaching the load-bearing capacity a cone shape is formed.
These anchors typically consist of a thick-walled, steel, tubular shaft filled with scrap metal or concrete and fitted with a conical tip. Steel flukes are often attached to the shaft to improve its hydrodynamic stability and to provide additional frictional resistance against uplift after installation. [1]
