What are the different types of building framing?

Arrangement (construction) Building framing is classified into two major categories: heavy-frame construction (heavy framing) if the vertical supports are few and heavy, as in wood framing, pole building framing, or steel framing; and light-frame construction (light-framing) if the supports are many and tiny. Light-frame construction is usually used for housing because it is easy to build and cheap. The typical light-frame house has 2x4s for studs and boards or 1x2s cut to fit for rafters and roof trusses. Heavy-frame construction is often used for industrial buildings because it is strong and durable. The typical heavy-frame building has 2x4s or 2x6s for studs and 4x4s or 4x6s for joists. The arrangement of heavy framing is usually based on mathematics rather than experience because you cannot see what's behind walls and floors.

The most common type of building framing is called "stick-built" because each piece of frame is tied directly to the one before it with no intermediate supporting members. This is the simplest type of framing to construct and install, but it is also the least stable because there is no physical connection between the frames. Stick-built houses were commonly built before engineered designs became available. These days, builders mostly use design templates that help them get their projects completed more quickly. Templates can be found in books, online, or through friends or neighbors who have built their own homes.

What is heavy framing?

Heavy framing is made up of frame members that are at least 6 inches in length (timber construction). Built-up roof trusses span long, unsupported regions between walls. They are too heavy for standard 2x4s to bear easily.

The word "heavy" is used to describe the frame because it is well-suited for bearing large loads. The load on a building is distributed through its frame to the supporting structure or ground. If the frame is not strong enough, it will break under the weight of the building material it supports. A light frame will bend under minimal pressure while a heavy one will fail immediately.

Frames can be divided into three general types: structural, decorative, and hybrid. Structural frames are used to support a building's load-bearing walls and roofs. They must be strong enough to withstand the force of gravity and any wind or other loading conditions acting on the building. Decorative frames are used in nonload-bearing structures such as windows and doors. They may be more ornamental than functional and thus need not be strong enough to support their own weight. Hybrid frames are combinations of structural and decorative elements built into a single frame. For example, some wall frames consist of two structural elements connected by a decorative element such as wood molding.

What two floor framing methods are used most often in current residential construction?

Platform framing is the most prevalent framing style in modern residential building, in which each storey is constructed on top of the preceding one. Builders will construct one-story platforms with eight- or nine-foot-high stud walls sitting on a subfloor. They will then build a second story on top of the first using similar materials and techniques.

Framing for interior walls is usually done with 2x4s, although 2x6s and 2x10s are also used depending on the design needs of the builder. The exterior walls are generally framed with lumber that has been treated for weather resistance. Load-bearing walls are also made from wood, but typically use 2x6 or 2x8 material instead of 2x4.

The roof is built first, to provide support for the rest of the structure. It is usually built out of plywood sheets fastened together with screws or nails. The ridge pole is the vertical member at the peak of the roof that supports the slope of the roof on both sides. It is usually made out of steel or wooden posts. The hips are the curved parts of the roof where it meets the walls at the end caps. They are usually supported by wood beams called bents. Ceiling joists are used to cover the open space between the roof and the wall framework. They are usually made of wood, but metal ones can be used as well.
