TIMBER BEAMS

Timber framing and "post-and-beam" construction are methods of building with heavy timbers to a certain extent than dimensional lumber such as 2" x 4" s. Conventional timber framing is the method of creating structures by means of heavy squared-off and carefully fitted and joined timbers with joints secured by large wooden pegs (larger versions of the mortise and tenon joints in furniture). It is routine in wooden buildings from the 19th century and before. The method comes from making things out of logs and tree trunks without modern high tech saws to cut lumber from the starting material stock. 

Using axes, adzes, and draw knives, hand-powered auger drill bits (bit and brace), and difficult woodworking, artisans or farmers could steadily assemble a building capable of bearing heavy weight without extreme use of interior space given over to vertical support posts. 

 Ever since this building method has been used for thousands of years in numerous parts of the world, there are many styles of momentous framing. 

These styles are frequently categorized by the kind of foundation, walls, how and where the beams intersect, the use of curved timbers, and the roof framing facts. Three essential types of timber frames in English-speaking countries are the box frame, cruck frame, and aisled frame.
