Floor Bearers

Joists are the timbers that then attach across the top of the bearers after which the timber or particle board floor is then attached.

Floor bearers. When you need more strength than one piece of timber can give you you can laminate two bearers together with glue and nails. Stump supported bearer and joist. Stump supported floors usually consist of a sub floor of horizontal bearers beams used in flooring are called bearers that support joists a smaller closer spaced beam on which the flooring material rests.

Bearers need almost continual support. Bearers are typically only 50mm deep so there is very limited space beneath the floor deck for ventilation and the floor is very close to the ground. Both factors mean that the floor deck can get damp.

The other common sub floor system is stump supported. How are framed floors installed. The bearers on this floor provide minimal distance between the ground and the floor.

The wood is water and weather proofed first and may be termite proofed as well when needed. Bearers supporting normal residential floors 42kg m2 maximum dead load 1 5kpa floor live load. This structure forms the base for the deck or timber floor or the second level floor.

Both will end up damp. Size grade floor load width mm single span bearers span values in mm 1200 1500 1800 2100 2400 3000 4000 5000 90x45 f7 1100 1100 1100 1000 900 0 0 0. By the time they get to the superficial flooring you can see structural damage in the form of weakened substructures can be extensive.

Beam and joist floor frames can be constructed on site or off site and transported in depending on your foundation. Common sense tells you that large floor joists can carry more load and spacing joists closer together also increases the load bearing capacity of a floor. Bearers are the timber or steel that attaches directly to the stumps in the ground that supports the deck of flooring structure.
