84-451: A building. Since this building method has been used for thousands of years in many parts of the world, many styles of historic framing have developed. These styles are often categorized by the type of foundation, walls, how and where the beams intersect, the use of curved timbers, and the roof framing details. A simple timber frame made of straight vertical and horizontal pieces with a common rafter roof without purlins . The term box frame

126-428: A flat wood panel in such a way that an object appears to rise out of the wood. Relief carving begins with a design idea, usually put to paper in the form of a master pattern which is then transferred to the wood surface. Most relief carving is done with hand tools, chisels and gouges , which often require a mallet to drive them through the wood. As wood is removed from the panel around the objects traced onto it from

168-555: A frame of load-bearing timber, creating spaces between the timbers called panels (in German Gefach or Fächer = partitions), which are then filled-in with some kind of nonstructural material known as infill . The frame is often left exposed on the exterior of the building. Gallery of infill types: The earliest known type of infill, called opus craticum by the Romans, was a wattle and daub type construction. Opus craticum

210-400: Is an old type of timber framing . The ridge board of their roof is not carried by king posts based on tie beams, but the ridge posts are based on the ground work. The German term for this construction is Firstständerhaus . The free-standing posts in the interior of the house and the posts in the gable or lateral walls were originally called Firstsäule ("ridge columns"). On a purlin roof

252-467: Is another alternative where straw bales are stacked for nonload-bearing infill with various finishes applied to the interior and exterior such as stucco and plaster. This appeals to the traditionalist and the environmentalist as this is using "found" materials to build. Mudbricks also called adobe are sometimes used to fill in timber-frame structures. They can be made on site and offer exceptional fire resistance. Such buildings must be designed to accommodate

294-614: Is attached to the peak of the timber frame after the frame is complete as a celebration. Historically, it was common for the master carpenter to give a speech, make a toast, and then break the glass. In Northern Europe, a wreath made for the occasion is more commonly used rather than a bough. In Japan, the "ridge raising" is a religious ceremony called the jotoshiki . In Germany, it is called the Richtfest . Relief carving Relief carving can be described as "carving pictures in wood". The process of relief carving involves removing wood from

336-454: Is not well defined and has been used for any kind of framing (with the usual exception of cruck framing). The distinction presented here is that the roof load is carried by the exterior walls. Purlins are also found even in plain timber frames. A cruck is a pair of crooked or curved timbers which form a bent (U.S.) or crossframe (UK); the individual timbers are each called a blade. More than 4,000 cruck frame buildings have been recorded in

378-455: Is now confusingly applied to a Roman stone/mortar infill as well. Similar methods to wattle and daub were also used and known by various names, such as clam staff and daub, cat-and-clay, or torchis (French), to name only three. Wattle and daub was the most common infill in ancient times. The sticks were not always technically wattlework (woven), but also individual sticks installed vertically, horizontally, or at an angle into holes or grooves in

420-502: Is readily available and log houses were favored, instead. Half-timbered construction in the Northern European vernacular building style is characteristic of medieval and early modern Denmark, England, Germany, and parts of France and Switzerland, where timber was in good supply yet stone and associated skills to dress the stonework were in short supply. In half-timbered construction, timbers that were riven (split) in half provided

462-468: Is technically called a nave . However, a nave is often called an aisle, and three-aisled barns are common in the U.S., the Netherlands , and Germany. Aisled buildings are wider than the simpler box-framed or cruck-framed buildings, and typically have purlins supporting the rafters. In northern Germany, this construction is known as variations of a Ständerhaus . Half-timbering refers to a structure with

504-400: Is used to describe timber frames with an infill of stone rubble laid in mortar the Romans called opus incertum . A less common meaning of the term "half-timbered" is found in the fourth edition of John Henry Parker's Classic Dictionary of Architecture (1873) which distinguishes full-timbered houses from half-timbered, with half-timber houses having a ground floor in stone or logs such as

546-515: The Kluge House which was a log cabin with a timber-framed second floor. Traditional timber framing is the method of creating framed structures of heavy timber jointed together with various joints, commonly and originally with lap jointing , and then later pegged mortise and tenon joints. Diagonal bracing is used to prevent "racking", or movement of structural vertical beams or posts. Originally, German (and other) master carpenters would peg

588-644: The structural frame of load-bearing timber is left exposed on the exterior of the building it may be referred to as half-timbered , and in many cases the infill between timbers will be used for decorative effect. The country most known for this kind of architecture is Germany, where timber-framed houses are spread all over the country. The method comes from working directly from logs and trees rather than pre-cut dimensional lumber . Hewing this with broadaxes , adzes , and draw knives and using hand-powered braces and augers (brace and bit) and other woodworking tools, artisans or framers could gradually assemble

630-618: The 12th century to the 19th century, and subsequently imported to North America, where it was common into the early 19th century. In a scribe frame, timber sockets are fashioned or "tailor-made" to fit their corresponding timbers; thus, each timber piece must be numbered (or "scribed"). Square-rule carpentry was developed in New England in the 18th century. It used housed joints in main timbers to allow for interchangeable braces and girts. Today, standardized timber sizing means that timber framing can be incorporated into mass-production methods as per

672-522: The 5- to 25-cm (2- to 10-in) range. The methods of fastening the frame members also differ. In conventional framing, the members are joined using nails or other mechanical fasteners, whereas timber framing uses the traditional mortise and tenon or more complex joints that are usually fastened using only wooden pegs. Modern complex structures and timber trusses often incorporate steel joinery such as gusset plates, for both structural and architectural purposes. Recently, it has become common practice to enclose

714-476: The Canadian Military Engineers undertook to construct airplane hangars using this timber construction system in order to conserve steel. Wood hangars were constructed throughout North America and employed various technologies including bowstring , Warren , and Pratt trusses, glued laminated arches, and lamella roof systems. Unique to this building type is the interlocking of the timber members of

756-677: The German ständerbohlenbau , timbers as in ständerblockbau , or rarely cob without any wooden support. The wall surfaces on the interior were often "ceiled" with wainscoting and plastered for warmth and appearance. Brick infill sometimes called nogging became the standard infill after the manufacturing of bricks made them more available and less expensive. Half-timbered walls may be covered by siding materials including plaster , weatherboarding , tiles , or slate shingles. The infill may be covered by other materials, including weatherboarding or tiles , or left exposed. When left exposed, both

798-495: The UK. Several types of cruck frames are used; more information follows in English style below and at the main article Cruck . Aisled frames have one or more rows of interior posts. These interior posts typically carry more structural load than the posts in the exterior walls. This is the same concept of the aisle in church buildings, sometimes called a hall church , where the center aisle

840-451: The assembly was held together with through-bolts. The through-bolts only held the assembly together but were not load-carrying. Shear plate connectors were used to transfer loads between timber members and metal. Shear plate connectors resembled large washers, deformed on the side facing the timber in order to grip it, and were through-fastened with long bolts or lengths of threaded rod. A leading manufacturer of these types of timber connectors

882-469: The complete skeletal framing of the building. Europe is full of timber-framed structures dating back hundreds of years, including manors, castles, homes, and inns, whose architecture and techniques of construction have evolved over the centuries. In Asia, timber-framed structures are found, many of them temples. Some Roman carpentry preserved in anoxic layers of clay at Romano-British villa sites demonstrate that sophisticated Roman carpentry had all

924-509: The distinctive "half-timbered", or occasionally termed, " Tudor " style, or "black-and-white". The most ancient known half-timbered building is called the House of opus craticum . It was buried by the eruption of Mount Vesuvius in 79 AD in Herculaneum, Italy. Opus craticum was mentioned by Vitruvius in his books on architecture as a timber frame with wattlework infill. However, the same term

966-636: The famous street known as The Shambles exemplifies this, where jettied houses seem to almost touch above the street. Historically, the timbers would have been hewn square using a felling axe and then surface-finished with a broadaxe . If required, smaller timbers were ripsawn from the hewn baulks using pitsaws or frame saws. Today, timbers are more commonly bandsawn, and the timbers may sometimes be machine- planed on all four sides. The vertical timbers include: The horizontal timbers include: When jettying, horizontal elements can include: The sloping timbers include: Historically were two different systems of

1008-610: The first people to publish the term "half-timbered" was Mary Martha Sherwood (1775–1851), who employed it in her book, The Lady of the Manor , published in several volumes from 1823 to 1829. She uses the term picturesquely: "...passing through a gate in a quickset hedge, we arrived at the porch of an old half-timbered cottage, where an aged man and woman received us." By 1842, half-timbered had found its way into The Encyclopedia of Architecture by Joseph Gwilt (1784–1863). This juxtaposition of exposed timbered beams and infilled spaces created

1050-634: The framing and infill were sometimes done in a decorative manner. Germany is famous for its decorative half-timbering and the figures sometimes have names and meanings. The decorative manner of half-timbering is promoted in Germany by the German Timber-Frame Road , several planned routes people can drive to see notable examples of Fachwerk buildings. Gallery of some named figures and decorations: The collection of elements in half timbering are sometimes given specific names: According to Craven (2019),

1092-522: The framing. The coating of daub has many recipes, but generally was a mixture of clay and chalk with a binder such as grass or straw and water or urine . When the manufacturing of bricks increased, brick infill replaced the less durable infills and became more common. Stone laid in mortar as an infill was used in areas where stone rubble and mortar were available. Other infills include bousillage , fired brick , unfired brick such as adobe or mudbrick , stones sometimes called pierrotage , planks as in

1134-444: The hobbyist, but others directed at professional carvers. Some carving tools are held with one hand while the carving is held in the other. But most relief carving requires that the wood panel be secured so that both hands may be on the carving tool. Much of the skill required for relief carving lies in learning to grip and manipulate tools to get the desired effect. Tool sharpening is also a necessary skill to learn, and dull tools are

1176-463: The joinery industry, especially where timber is cut by precision computer numerical control machinery. A jetty is an upper floor which sometimes historically used a structural horizontal beam, supported on cantilevers, called a bressummer or 'jetty bressummer' to bear the weight of the new wall, projecting outward from the preceding floor or storey. In the city of York in the United Kingdom,

1218-414: The joints with allowance of about 1 inch (25 mm), enough room for the wood to move as it ' seasoned ', then cut the pegs, and drive the beam home fully into its socket. To cope with variable sizes and shapes of hewn (by adze or axe) and sawn timbers, two main carpentry methods were employed: scribe carpentry and square rule carpentry. Scribing or coping was used throughout Europe, especially from

1260-453: The necessary techniques for this construction. The earliest surviving (French) half-timbered buildings date from the 12th century. Important resources for the study and appreciation of historic building methods are open-air museums . The topping out ceremony is a builders' rite , an ancient tradition thought to have originated in Scandinavia by 700 AD. In the U.S., a bough or small tree

1302-741: The number of knots, the moisture content, the temperature, the grain direction, the number of holes, and other factors. There are design specifications for sawn lumber, glulam members, prefabricated I-joists , composite lumber , and various connection types. In the United States, structural frames are then designed according to the Allowable Stress Design method or the Load Reduced Factor Design method (the latter being preferred). The techniques used in timber framing date back to Neolithic times, and have been used in many parts of

1344-480: The panels span considerable distances and add rigidity to the basic timber frame. An alternate construction method is with concrete flooring with extensive use of glass. This allows a solid construction combined with open architecture. Some firms have specialized in industrial prefabrication of such residential and light commercial structures such as Huf Haus as low-energy houses or – dependent on location – zero-energy buildings . Straw-bale construction

1386-413: The pattern, the objects themselves stand up from the background wood. Modelling of the objects can take place as soon as enough background has been removed and the object edges are trimmed to the pattern lines. In order to secure the wood panel, a workbench with fixtures like bench-dogs, carver's screws or clamps, is necessary. Carving tools come in a wide variety of shapes and sizes, some aimed strictly at

1428-419: The poor thermal insulating properties of mudbrick, however, and usually have deep eaves or a veranda on four sides for weather protection. Timber design or wood design is a subcategory of structural engineering that focuses on the engineering of wood structures. Timber is classified by tree species (e.g., southern pine, douglas fir, etc.) and its strength is graded using numerous coefficients that correspond to

1470-529: The position of posts and studs: Ridge-post framing is a structurally simple and ancient post and lintel framing where the posts extend all the way to the ridge beams. Germans call this Firstsäule or Hochstud . In the 1930s a system of timber framing referred to as the "modern timber connector method" was developed. It was characterized by the use of timber members assembled into trusses and other framing systems and fastened using various types of metal timber connectors. This type of timber construction

1512-6317: The ridge posts carry the ridge purlin. On the latter are hung the sloping rafters to which the roof is fixed. This type of Firstständerhaus was predominantly built around the 15th century in Baden region.

1554-728: The roof trusses and supporting columns and their connection points. The timber members are held apart by "fillers" (blocks of timber). This leaves air spaces between the timber members which improves air circulation and drying around the members which improves resistance to moisture borne decay. Timber members in this type of framing system were connected with ferrous timber connectors of various types. Loads between timber members were transmitted using split-rings (larger loads), toothed rings (lighter loads), or spiked grid connectors. Split-ring connectors were metal rings sandwiched between adjacent timber members to connect them together. The rings were fit into circular grooves on in both timber members then

1596-547: The term: was used informally to mean timber-framed construction in the Middle Ages. For economy, cylindrical logs were cut in half, so one log could be used for two (or more) posts. The shaved side was traditionally on the exterior and everyone knew it to be half the timber. The term half-timbering is not as old as the German name Fachwerk or the French name colombage , but it is the standard English name for this style. One of

1638-585: The timber structure entirely in manufactured panels such as structural insulated panels (SIPs). Although the timbers can only be seen from inside the building when so enclosed, construction is less complex and insulation is greater than in traditional timber building. SIPs are "an insulating foam core sandwiched between two structural facings, typically oriented strand board" according to the Structural Insulated Panel Association. SIPs reduce dependency on bracing and auxiliary members, because

1680-606: The world during various periods such as ancient Japan, continental Europe, and Neolithic Denmark, England, France, Germany, Spain, parts of the Roman Empire , and Scotland. The timber-framing technique has historically been popular in climate zones which favour deciduous hardwood trees, such as oak . Its northernmost areas are Baltic countries and southern Sweden. Timber framing is rare in Russia, Finland, northern Sweden, and Norway, where tall and straight lumber, such as pine and spruce,

1722-491: Was the Timber Engineering Company, or TECO, of Washington, DC. The proprietary name of their split-ring connectors was the "TECO Wedge-Fit". Timber-framed structures differ from conventional wood-framed buildings in several ways. Timber framing uses fewer, larger wooden members, commonly timbers in the range of 15 to 30 cm (6 to 12 in), while common wood framing uses many more timbers with dimensions usually in

1764-472: Was used for various building types including warehouses, factories, garages, barns, stores/markets, recreational buildings, barracks, bridges, and trestles. The use of these structures was promoted because of their low construction costs, easy adaptability, and performance in fire as compared to unprotected steel truss construction. During World War II, the United States Army Corps of Engineers and
