The typical deck railing is generally built from pressure treated lumber. [14] Posts on a deck are also typically pressure treated wood and standard sizes are 4x4, 6x6, and 8x8. These posts give structural support to the railing assembly and are the most critical part for the safety of the guard rail assembly. [15]
An example of a common residential guard rail (US) or handrail (Brit.) is a wood railing around a deck or patio. In the US this is typically built on-site from pressure treated lumber thus featuring a simplistic design of vertical baluster spaced every 3.5 inches (8.9 cm) demonstrating compliance with building codes (standards).
Initially a linkspan was a ramp that was attached to the pier at one end and was suspended above the water at the other. The height above the water was controlled either by hydraulic rams or cables, these types of linkspans were less well designed for the various conditions of the tide, wave and current and so were superseded by underwater tank linkspans that through compressed air can be ...
In naval architecture, a taffrail is the handrail around the open deck area toward the stern of a ship or boat. The rear deck of a ship is often called the afterdeck or poop deck. Not all ships have an afterdeck or poop deck. Sometimes taffrail refers to just the curved wooden top of the stern of a sailing man-of-war or East Indiaman ship.
A bow visor is a feature of some ships, in particular ferries and roll-on/roll-off ships, that allows the bow to articulate up and down, providing access to the cargo ramp and storage deck near the water line. [1] However, in modern ferry design over the last 45 years, bow visors have given way to clam doors. Instead of one large visor, two ...
End posts to which the tensioning hardware attaches must be constructed so that they will not deflect perceptibly. Post spacing: Intermediate posts are posts which provide mounting for the top rail and have a vertical row of holes to support the cable as it passes through them. Since the post to post spacing is a primary driver of cable ...
A fishplate, splice bar or joint bar is a metal or composites connecting plate used to bolt the ends of two rails into a continuous track. The name is derived from fish , [ 1 ] a wooden reinforcement of a "built-up" ship's mast that helped round out its desired profile. [ 2 ]
They additionally have a locking mechanism (properly known as "the gate") across the top of the "U" to prevent the oar from unintentionally popping out of the rowlock. A rowlock cut into the top strake of a boat. In some, largely older, strict terminologies, a rowlock is a U-shaped cut-out in the top strake of a boat (usually the wash-strake ...
