2. Precast concrete lifting anchor system - Wikipedia

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

   When selecting an anchor, consider the element formwork and the ease of placement and securing of the anchor prior and during the pouring of the concrete. For example, some of the anchors shown in figures 4-6, can be placed into thin wall elements as the anchor chair maintains the position relative to the element thickness.

3. Concrete cover - Wikipedia

   en.wikipedia.org/wiki/Concrete_cover

   Concrete cover, in reinforced concrete, is the least distance between the surface of embedded reinforcement and the outer surface of the concrete (ACI 130). The concrete cover depth can be measured with a cover meter. The purpose of concrete cover is to protect the reinforcement from corrosion, fire, and other potential damage.

4. Anchor bolt - Wikipedia

   en.wikipedia.org/wiki/Anchor_bolt

   Anchor bolts are used to connect structural and non-structural elements to concrete. [2] The connection can be made by a variety of different components: anchor bolts (also named fasteners), steel plates, or stiffeners. Anchor bolts transfer different types of load: tension forces and shear forces. [3]

5. 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 ...

6. Reinforced concrete - Wikipedia

   en.wikipedia.org/wiki/Reinforced_concrete

   The minimum concrete cover is normally regulated by design or building codes. If the reinforcement is too close to the surface, early failure due to corrosion may occur. The concrete cover depth can be measured with a cover meter. However, carbonated concrete incurs a durability problem only when there is also sufficient moisture and oxygen to ...

7. Tieback (geotechnical) - Wikipedia

   en.wikipedia.org/wiki/Tieback_(geotechnical)

   Grouted tiebacks can be constructed as steel rods drilled through a concrete wall out into the soil or bedrock on the other side. Grout is then pumped under pressure into the tieback anchor holes to increase soil resistance and thereby prevent tiebacks from pulling out, reducing the risk for wall destabilization.
