2. Anchor bolt - Wikipedia

   en.wikipedia.org/wiki/Anchor_bolt

   torque controlled: the anchor is inserted into the hole and secured by applying a specified torque to the bolt head or nut with a torque wrench. A particular sub-category of this anchor is called wedge type. As shown in the figure, tightening the bolt results in a wedge being driven up against a sleeve, which expands it and causes it to ...

3. Wall plug - Wikipedia

   Wall plugs. A wall plug (UK English) also known as an anchor (US) or "Rawlplug" (UK), is a fibre or plastic (originally wood) insert used to enable the attachment of a screw in a material that is porous or brittle, or that would otherwise not support the weight of the object attached with the screw.

6. Blocking (construction) - Wikipedia

   en.wikipedia.org/wiki/Blocking_(construction)

   The intervals for the blocks are specified in the building code or as calculated by a structural engineer. Blocking also resists the rotational movement, or twisting, of floor joists as they deflect under load. This may take the form of diagonal cross bracing, or herringbone, bracing between floor joists.

7. Powder-actuated tool - Wikipedia

   en.wikipedia.org/wiki/Powder-actuated_tool

   Powder-actuated tools are often used because of their speed of operation, compared to other processes such as drilling and then installing a threaded fastener. They can more easily be used in narrow or awkward locations, such as installing steel suspension clips into an overhead concrete ceiling.

8. 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.

9. Screw piles - Wikipedia

   en.wikipedia.org/wiki/Screw_piles

   Helical anchors consist of an extendable steel shaft with helical bearing plates. Piles or piers refer to strong base elements that withstand or transfer vertical/horizontal loads. Anchors are piles utilised only in tension applications like restraining wall tiebacks or vertical ground anchors made to resist overturning forces.
