Anchorbeam joints Early Dutch Barn frames often had large open areas for threshing and bays on the sides for animals. These barns were composed of H-shaped bents that supported purling plates. These bents had huge crossbeams called anchorbeams, panning the threshing floor. These anchorbeams could be as large as 12 x 24 inches. Bay is the area between bents. Beetles are large wooden mallets weighing as much as 20 pounds that are used to fit joints together. They are sometimes called persuaders.  A bent is a vertical unit or cross sectional unit and can weigh 1000's of pounds. A blind mortise does not extend through the post. Braces are diagonal members that connect posts and beams. They prevent the lateral movement in the frame to keep the building plumb and square. A Bladed Scarf is a method of splicing together two timbers. A chamfer is a beveled edging used along a tenon to make it fit easier into its mortise. A Collar Ties at the gable ends of the rafters are timbers that provide a nailing surface for boards. A Cross Beams join the upright posts of the bents together A Dovetail Lap Joint a flared or tapered joint with great resistance to pulling apart. Drawbore is a tenon pinned from the side; but instead of assembling and drilling straight thru the joint the hole is offset a small amount, making the joint much stronger. Floor joists support the floor above and are exposed as ceiling beams below. A floor mortise is in the sub floor and accepts the tenons which are on the bases of the bents A Gin Pole is a strong light pole with ropes and pulleys to raise a bent Girts are the horizontal beams which join bents together. Half Lap the most often used joint for splicing beams House wrights are craftsman and builders of timber frame homes. A Jetty or overhang on the second floor was not uncommon in European buildings where there was a timber shortage. This was to avoid a weak place between the floors where the timbers were joined. Jowled posts also called flared, tapered, or shouldered are wider at the top to support several timbers.. The king post is the center post of a bent. A knee brace is the framed diagonal support between post and beam using mortise and tenon joints. A lap joint is the most basic of all timber frame joints. All joints are a variation of lap joints. The timbers are notched where they meet.. A mortise is the slot or cavity into which the tenon which fits into.
A mortise and tenon joint is basic to all timber frame construction. A mortise is a cavity or area removed from the wood while a tenon is shaped to fit in the cavity. Pike poles long wooden poles used to raise the bents before the use modern cranes. Plates join the bents. In barns before 1800 plates have been found that were over 60 feet long. This was before the decline in the availability of long straight timbers as the virgin forest was logged out. Posts are the upright members of bents. a post tenon is on the base of the post of the bent and locks in the floor mortise Purlins are the horizontal roofing members, which connect bents. TheSaltbox House was originally an expansion of the home with a lean to on the back. This original American innovation worked well in the harsh winds of New England. The name was taken from the salt storage bins of the day.. Rafters are the sloping members of a frame can also be part of a bent
Rafter seat where a rafter sits on a purlin or plate a cut area holds rafter in place. A Relish is an old term, which means remainder or left over A Scarf joint is separate timbers that are cut and spliced together in such a way so that when a wedge is driven into the joint it locks the two timbers together, making the joint stronger than a single timber. A Slabbing Rail is used to cut square posts out of round timbers. Stain occurs when green wood is stacked to dry with no flow. A strongbox is boards clamped to the bent to hold it square and keep it from spreading while it is being raised. Structural insulated panels (sip) have both insulating and load-bearing abilities. Sips' are used for sidewalls and have construction sheeting on the exterior, rigid insulating foam in the middle 3.5 to 9.25 inches thick and drywall or paneling on the other side. Openings for doors and windows are cut into the panels.
A Summer beams floor systems usually have one or more main timbers or girders that carry the common joists.. A through mortise extends through the post. Tie beams are horizontal members of bents. Temporary pegs are used while the frame is raised with permanent pegs hammered in place as the frame is finished. Trusses are a triangle of timbers used to span distances. Wane outer surface area of the log, which may be cut and discarded. Wedged Dovetail Tenon is another wedged version of the mortise and tenon joint, which is exceptionally strong |
