  2. 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 ...

  3. Pipe support - Wikipedia

    en.wikipedia.org/wiki/Pipe_support

    In case of anchor which is bolted to concrete, a special type of bolt is required called Anchor Bolt, which is used to hold the support with concrete. In this type of support, normal force and friction force can become significant. To alleviate the frictional effect Graphite Pad or PTFE plates are used when required. Pipe Anchors (Permali Cold ...

  4. Precast concrete lifting anchor system - Wikipedia

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

    The weight of the element can be determined by the calculated volume, and using the specific gravity (normal weight reinforced concrete is approximately 24 kN/m3). Establishing the lifting anchor positions will influence the rigging arrangements used and therefore the static analysis of the rigging should be determined.

    Other varieties of wall plug are mechanical anchors for heavy duty loads and hollow wall fixings for fixing to plasterboard. The first mechanical anchor, the Rawlbolt, was designed in the 1930s by the Rawlplug company and the first fixing for hollow walls was the Toggle Bolt, which was also designed by Rawlplug in 1941.

    Structural bolt DIN 6914 with DIN 6916 washer and UNI 5587 nut. A threaded fastener has internal or external screw threads. [7] The most common types are the screw, nut and bolt, possibly involving washers. Other more specialized types of threaded fasteners include captive threaded fasteners, stud, threaded inserts, and threaded rods.

  7. Anchor - Wikipedia

    en.wikipedia.org/wiki/Anchor

    The weight of the anchor chain can be more than that of the anchor and is critical to proper holding. Permanent moorings use large masses (commonly a block or slab of concrete) resting on the seabed. Semi-permanent mooring anchors (such as mushroom anchors ) and large ship's anchors derive a significant portion of their holding power from their ...

  9. Concrete cone failure - Wikipedia

    en.wikipedia.org/wiki/Concrete_cone_failure

    The tension failure loads predicted by the CCD method fits experimental results over a wide range of embedment depth (e.g. 100 – 600 mm). [2] Anchor load bearing capacity provided by ACI 349 does not consider size effect, thus an underestimated value for the load-carrying capacity is obtained for large embedment depths.
