Cute Young Brunette Girl Outside At The Old Pole Barn

On two walls, usually the long wall, the heavy 'beam' function of post and beam or 'top plate' of platform framing methods is analogously performed by the heavier top girts (wider 2x lumber) of those walls. In the technique, the girts are through-bolted by large carriage bolts, and both an inner and outer girt are generally used to support the roof loading, which is frequently a truss roof supporting purlins, not stick built ridge board and rafter construction using rafters. When used, some rafters may be attached directly to the poles. Purlins might also be used when rafters are spaced farther apart, for in either case, purlins are like girts, oriented at right angles to the truss or rafters they cross, as well as the long sheet like metal roofing elements commonly used in roofing and siding Pole buildings.
The techniques originated in the pole barn, which was a quick and economical method of adding outbuildings on a farm as agriculture shifted to equipment dependent and capital intensive agriculture—necessitating sheltering tractors, harvesters, wagons and the like in much greater quantities and sizes. Around North America, many pole built structures are still readily seen in rural and industrial areas, for the galvanized steel siding and roofing of the thirties has proven to be very durable as was much of the shed style vertically oriented plank siding.
In modern developments the Pole Barns of the 30s have become 'Pole Buildings' under the influence of new building materials such as inexpensive metal roof and siding products in stylish varieties and so today serve a more general purpose, such as housing, commercial use, or storage. In the process more often than not, the poles have become posts of squared off pressure treated timbers. These structures have the potential to replicate the functionality of other buildings, but they are more affordable and require less time to construct. The most common use for pole buildings is storage as it was on the farms, but today it is of automobiles or boats along with many other household items that would normally be found in a residential garage, or commercially as the surroundings for a light industry or small corporate offices with attached shops. The reason these buildings are so affordable is because they use a technique called Pole Framing.
The posts provide a strong vertical anchors and supports for attaching the shell of the building which is connected by bolted through girts running ribbon like horizontally like bands at different heights generally about two feet apart. The posts replace the studs commonly used in the more familiar platform framing construction techniques people see in housing. The exterior walls are indirectly attached to the outer edge of the posts onto girts which run around the building like wooden bands at the same fixed heights about two feet apart from where the upper girts support the roof and rafters at intervals about 2 feet on center to a bottom girt that is possibly under the sub-floor level supporting the rafters of a wooden floor. The roof is attached to the top girts (normally both) of the longer wall usually via a standard ridge beam and rafter or more commonly, using a truss system which can span longer distances and requires no interior posts and beams with modern tech.
