Box beam consists of 2 x 4” / 50 x 100 mm profiles glued and nailed between two plywood boards, while laminated-strand lumber beam is a factory made beam with several wood-based boards joined together. If the two parts of wooden planks are screwed or nailed together, it is called build-up beam, which usually has a width of multiple of 1 ½” / 90 mm. The most common is probably simple cut timber beam. Different types of tiny house floor framing beamsĪpart from the materials, floor beams also differ in a way how the beam itself is put together. Beginning with the material, apart from the wooden floor beams there are also various composite ones combining materials such as wood, plywood, particle board, laminate, steel and others. As almost in any part of DIY building, you can also enhance the environmental friendl y aspect of your small cabin or tiny house and look for recycled beams, which come from demolitions of old buildings, etc. Floor framing joists and their connectionsĪs well as with the other parts of tiny house floor framing, there is more types of floor joists or beams to choose from. Similarly, wooden planks running alongside the beams called ledgers can support and hold together the floor joists. Metal connectors called joist hangers can hold together joists and beam in cases where the board height is to be reduced by the height of the joists. In spliced joist, a long enough scab (piece of wood) is attached with sufficient number of nails to two joists to hold them together. The two adjusting joists can can be simply nailed together to create one load-bearing piece, so called lapped joist. The installation of the joists and beams for a timber floor structure also offers several options. Around stairs or in other cases when a larger opening is needed, its “boarders” – the joists and bearers on the opening‘s edges need to be doubled for statics reasons. ![]() There are more possibilities of how to place these bracing elements. Tiny house floor framing bracingĪ crucial thing in the timber floor framing construction is so called blocking – a bracing consisting of wooden beams placed perpendicularly between the joists preventing them from tilting, twisting or moving.

Regarding the “simpler” approach to tiny house floor framing and the single level frame, it is used for example in structures like tool sheds, kids playhouses, garden decorative mini-structures and other tiny constructions, which do not require a great load-bearing capacity nor a thermal insulation. Polygonal gazebo floor frame on ground screws Wooden floor frames on different types of foundations In all cases it is important to make sure you understand your small house blueprints correctly and have the right sizes of the elements. On the other hand, the latter option with bearers supporting the floor joists provides better carrying capacities as well as load distribution and also has easier assembly method. In the first case of the load-bearing components being on a single level, the overall floor height is smaller, which also means reducing the amount of material needed and the costs. ![]() ![]() They can be supported either by foundations directly or by floor bearers (beams) laying on foundations and running in direction perpendicular to the joists. Placed in repetitive pattern with perpendicular bracing elements in between them, the joists can be connected with metal connectors, through carpentry joints or various different fastening methods. ![]() Timber floor framing constructionĪ standard timber floor framing construction consists primarily of floor joists.
