2. Anchor bolt - Wikipedia

   en.wikipedia.org/wiki/Anchor_bolt

   Tapcon screws are a popular anchor that stands for self tapping (self threading) concrete screw. Larger diameter screws are referred to as LDT's. This type of fastener requires a pre-drilled hole—using a Tapcon drillbit—and are then screwed into the hole using a standard hex or phillips bit.

   A formwork blockout or recess former fitted to the edge formwork of a post-tensioned concrete member, and that creates a temporary void space external to the prestressing anchor to allow the anchor block or similar to be fitted after formwork stripping.

4. List of screw and bolt types - Wikipedia

   en.wikipedia.org/wiki/List_of_screw_and_bolt_types

   The screw itself should be drilled a minimum of 1" into the concrete to hold effectively and a maximum of 1-3/4" or the threads will wear and will lose holding power. Ideally 1-1/4" to 1-1/2" of screw thread in the concrete. [1] So for example, if a 1/2" board is being screwed onto the concrete, a 1-3/4" to 2" concrete screw should be used ...

5. Precast concrete lifting anchor system - Wikipedia

   en.wikipedia.org/wiki/Precast_concrete_lifting...

   F/n = 23 kN per anchor during site lifting (n = 2 lifting anchors) Reference to the load capacity tables provided by the anchor manufacturer is required to make an anchor selection for the specific concrete strengths at the time of lifting. Hence the great of the two calculated anchor capacities required at the concrete strength of the initial ...

6. Pipe support - Wikipedia

   en.wikipedia.org/wiki/Pipe_support

   A pipe anchor is a rigid support that restricts movement in all three orthogonal directions and all three rotational directions, i.e. restricting al the 6 degrees of freedom This usually is a welded stanchion that is welded or bolted to steel or concrete. [2] In case of anchor which is bolted to concrete, a special type of bolt is required ...

7. Concrete cone failure - Wikipedia

   en.wikipedia.org/wiki/Concrete_cone_failure

   Under tension loading, the concrete capacity of a single anchor is calculated assuming an inclination between the failure surface and surface of the concrete member of about 35°. The concrete cone failure load N 0 {\displaystyle N_{0}} of a single anchor in uncracked concrete unaffected by edge influences or overlapping cones of neighboring ...
