Subfloor Construction Details

Your sketch should depict the floor s basic shape and layout complete with any additional features like alcoves nooks and staircases.

Subfloor construction details.

Draw up a basic floor framing plan. Good subfloor construction depends on material selection and attention to critical details. Although cold formed steel framing for floor systems also is permitted by the irc it is not covered here. We will sand the floor 3 times once with coarse sand paper once with medium sand paper and once with fine sandpaper until it is smooth and even.

All subfloor framing was separated from the concrete or concrete blocks depending on the foundation wall construction by a bitumen impregnated fabric damp proof course dpc to protect the timber from moisture. So the subfloor and maple are installed. Or the subfloor may be made of plywood or other panel products that are laid perpendicular to the joists. Extremely long spans staircases or interior walls typically require additional support which can complicate your framing.

69 chapter 4 floor construction woodframe floor systems and concrete slab on grade floors are discussed in this chapter. This process takes 4 5 days. On wood frame floors the subflooring provides a continuous structural surface over the floor joists. Now we get on our giant ride on sander and sand that wood.

Timber used for subfloor framing was commonly wet or green. Before you begin cutting or measuring grab a pencil and paper and sketch an outline of your floor. These subfloors do not have the solidness of a concrete slab but offer a wide variety of potential floor covering. Use a solvent based glue that meets astm d3498 performance standards.

Subflooring provides a base for finish flooring and also serves as a platform during construction. In basements and in homes with slab on grade foundations the subfloor may simply be a concrete slab. Like other framing components beam and joist floor frames are often pre constructed transported to the site and attached to stumps or less commonly to a slab foundation although they can be constructed on the site as well. The subfloor is the foundation beneath finish flooring materials.

It may be made of boards laid either at right angles or diagonally across joists. In cases where latex subfloor glue is required careful selection is necessary due to the wide range of performance between brands. The subfloor builds on those and attaches by various means particular to the support structure but the support and subfloor together always provides the strength of a floor one can sense underfoot. Subfloor construction floors may be built on beams or joists 1 or use structures like prefabricated hollow core slabs.

This is a messy dusty process.
