This image provides a labeled diagram illustrating the terminology of different parts of a wooden deck. Here's a description of each labeled component:
* Decking: These are the flat boards that form the walking surface of the deck. They are typically made of wood or composite materials and are laid out horizontally with small gaps between them (indicated as "⅛" gaps").
* Cap Rail: This is the topmost horizontal rail of the deck railing. It provides a finished look and a comfortable place to rest a hand.
* Top Rail: Located below the cap rail, this is another horizontal rail that contributes to the safety and structure of the railing.
* Baluster: These are the vertical posts that are spaced along the railing between the top and bottom rails. They prevent people from falling off the deck and can be decorative.
* Rail Post: These are the main vertical posts that support the entire railing structure, including the top rails and balusters. They are typically more substantial than the balusters.
* Rim Joist: This is the outermost joist that runs around the perimeter of the deck frame. It provides support for the ends of the decking and helps to enclose the structure.
* Joist: These are the horizontal structural members that run parallel to each other and support the decking. They are typically attached to the ledger board on one side and the rim joist on the other.
* Joist Hanger: This is a metal bracket used to securely attach the joists to the ledger board or the rim joist.
* Bridging: These are cross braces or solid blocks installed between the joists. They help to distribute weight across multiple joists and prevent them from twisting or sagging, adding stability to the deck.
* Ledger: This is a horizontal beam that is attached directly to the house wall. One end of the deck joists is typically attached to the ledger.
* Post: These are the vertical support columns that carry the weight of the deck. They are typically made of wood and are placed on concrete footings.
* Beam: These are horizontal structural members that are supported by the posts. The joists often rest on top of or are attached to the beams.
* Post Anchor: This is a metal fitting that connects the bottom of the post to the concrete footing, providing a secure and stable connection.
* Concrete Footing: This is the concrete base that is poured into the ground to provide a stable and load-bearing foundation for the posts.
* Stringer: This is the angled structural member that supports the stair treads and risers. It runs from the deck down to the ground.
* Tread: This is the horizontal part of a stair step that you step on.
* Riser: This is the vertical part of a stair step located between two treads.
