What is the beams?

The

faener beam is basically a rectangle made of two by four cuts, which is fixed together with the fasteners of the metal straps. The frame members of the beam beams are attached together so that the lattice beam frame has a thickness of 3.5 inches (about 8.89 cm), which is the thickness of the standard two by four. After the basic rectangle of the beam, the cross reinforcement inside the rectangle for special support is installed. When framing any roof or floor, the main problem is whether framing extends the distance greater than 16 feet (about 4.88 m) without sagging. It is also possible whether structural framing for the roof or floor will support the weight of walls or live loads such as snow or rain. The droppings can bridge distances of up to 24 to 36 feet (about 7.3 to 10.9 m) without supporting load -bearing walls or columns. Typical widths of beams can range from 16 to 24 inches (about 40.6 to 60.9 cm), depending on the structural force required by the builder.

Mainly trusses serve as a means for structural support for floors and roofs; However, because the beam is not solid and is framed from the lumber, cabling, plumbing and pipes can be installed by space in the trips without the need to cut beams. Since the trusses are so wide, the ceiling or the floor space that is created by these framework members is generally wide enough to insulate heavier than the space created by conventional beams, which are usually two or two-twos that are 9 to 12 inches (about 22.9 to 30.5 cm).

Because the trusses are prefabricated and built using special fasteners, they are able to withstand an extraordinary amount of weight, allowing them to be deployed up to 24 inches (about 60.9 cm), rather than more 12 to 16 inches (about 22.9 to 40.6 cm). Beauties usually come from a factory with notches at the ends,to fit through the window sill; However, the ends of the lattice beams must usually be closed when using a 3/4 inches (about 1.9 cm) plywood. Adding plywood is usually necessary to connect beams with floor framing and also to provide a closed lattice system that will be tight air. However, the trusses manufacturers can recommend that the builder use two 3/4 inches (about 1.9 cm) instead of one.
