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. 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.

4. 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. Mortise and tenon - Wikipedia

   en.wikipedia.org/wiki/Mortise_and_tenon

   Through tenon: a tenon that passes entirely through the piece of wood it is inserted into, being clearly visible on the rear side. Loose tenon: a tenon that is a separate part of the joint, as opposed to a fixed tenon that is an integral part of one of the pieces to be joined. Biscuit tenon: a thin oval piece of wood, shaped like a biscuit [17]

8. Wedge - Wikipedia

   en.wikipedia.org/wiki/Wedge

   Consider a block that is to be lifted by a wedge. As the wedge slides under the block, the block slides up the sloped side of a wedge. This lifts the weight F B of the block. The horizontal force F A needed to lift the block is obtained by considering the velocity of the wedge v A and the velocity of the block v B. If we assume the wedge does ...

9. 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.
