How can I choose the right size of beams?

The choice of the right floor beam size depends on your construction application, beam gaps and several other factors. These include the length of the span, as well as the type and degree of the timber used. Conventional beam gaps are 12 inches (304.8 mm), 16 inches (406.4 mm) and 24 inches (609.6 mm). The amount of weight to be supported can also be a significant factor, it can also be. For example, the stronger the wood, the greater the weight will be able to support after a longer range.

When determining the size of the floor beam, measure the span length. The span is an internal dimension from support at one end to support at the opposite end. Another factor to consider is the use of the beams that will be used and the amount of weight that the floor will have to support. For example, a standard outdoor deck will not be required to support as much weight as the dining room floor if the deck with a large hot tub.

For a pitch of beams of 12 inches (304.8 mm), longer lengths of less lumber can be used. In thatThe MTO example will be a larger number of beams supporting the weight of the deck or floor. So for the deck 8 feet long (2.44 m) would have to be the redwood beam of the 2 2 x 6 (50.8 x 152.4 mm) wood. The larger size of the floor beams would be absolutely acceptable, while the smaller size would not be. The size of the 2 x 6 beams is suitable for most class 2 wood types for 8 feet (2.44 m).

structure with a length of 10 feet (3.05 m) and beams set 12 inches (304.8 mm) would require the use of 2 x 8 floor (50.8 x 203 mm). If the beam gap is 16 inches (406.4 mm), the beam size of 2 x 8 should be used, although the length is only 8 feet (2.44 m). With a 24 -inch beam gap (609.6 mm), the same 2 x 8 barely meets the minimum requirement for a length of 8 feet (2.44 m). A better choice would be to use the size of the beams 2 x 10 (50.8 x 254 mm). The use of timber 1. The degree provides more structural support with less beam size.

Calculations for choosing the size of the floor of the floor depends on the degree and youPU lumber, span length and gaps. In addition, the weight of living and dead loads should be considered. The dead load concerns the weight of all materials involved in a building or deck. Live costs are adding furniture and people using an area.

There are formulas or engineering programs that can be referred to when solving unusual span lengths or varieties of lumber. Many areas are also subject to building regulations and these requirements must be followed. In case of doubt, the transition to the next floor may be up the size of the beams, but it is worth removing worries.
