50-535: Altenahr is situated on the river Ahr , on the northeastern edge of the Ahr Hills . part of the Eifel mountains, approximately 10 kilometres west of Bad Neuenahr-Ahrweiler and about 35 kilometres southwest of Bonn . The municipality of Altenahr comprises the following parishes: Altenahr, Altenburg, Kreuzberg and Reimerzhoven. Altenahr borders on the following neighbouring municipalities, listed clockwise from

100-451: 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

150-566: 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

200-520: A height of 474 m above  sea level (NHN) . It then flows through the Schwanenweiher pond below Blankenheim Castle . The stream, which runs in a south-easterly direction, through the valley meadows of upper Ahr valley, has not cut very deeply into the heights of the Eifel. Much of the upper Ahr valley is protected and follows the B 258 federal road . Below the hamlet of Ahrdorf in

250-467: 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

300-704: Is nevertheless the largest contiguous red wine -growing area in Germany, noted especially for wines made from the Spätburgunder ( Pinot noir ) grape. The Red Wine Trail runs through the southern slopes of the lower Ahr Valley, passing inter alia the former government bunker . Timber-framed house Timber framing ( German : Fachwerkbauweise ) and "post-and-beam" construction are traditional methods of building with heavy timbers , creating structures using squared-off and carefully fitted and joined timbers with joints secured by large wooden pegs. If

350-454: 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

400-455: 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

450-510: 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

500-474: 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

550-400: 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

600-431: The Eifel , in the cellar of a timber-frame house near the castle of Blankenheim. After 18 kilometres (11 mi) it crosses from North Rhine-Westphalia into Rhineland-Palatinate . The Ahr flows through Ahr valley or Ahrtal , passing through the towns of Schuld , Altenahr and Bad Neuenahr-Ahrweiler . Between Remagen and Sinzig (south of Bonn ), at about 50 metres (160 ft) above sea level, it flows into

650-521: 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

700-644: 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

750-624: 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

800-522: 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

850-565: The Ahr valley beginning at the latest in Roman times, evidenced by the Roman villa near Ahrweiler. Owing to their isolated location, the upper and middle parts of the course were sparsely populated. That began changing in the mid-19th century. The development of settlements and transportation routes (including three railway lines) and the expansion of the area used for agriculture in the Ahr valley led to

900-487: 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

950-681: 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

1000-559: The Rhine. The length is roughly 89 kilometres (55 mi), of which 68 kilometres (42 mi) is within Rhineland-Palatinate. The Ahr has a gradient of 0.4 percent in its lower course, and 0.4 to 0.8 percent in its upper course. The Ahr and its tributaries are a main drainage system of the eastern Eifel. The watershed is approximately 900 square kilometres (350 sq mi). There were isolated settlements in

1050-503: 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

1100-451: 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

1150-469: 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

1200-519: 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

1250-472: The east and initially follows a very winding course. Here the river is accompanied by the B ;267 , although it does not follow every loop in the river. In Altenahr, the largest bend in the river beings; it is protected because of its flora and fauna. From here, the valley becomes a gorge bordered by the steep cliffs of the Ahr Hills . From Reimerzhoven the valley sides are dominated by vineyards, especially on

1300-636: 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

1350-408: The few natural river mouths on the Rhine and is under protection . The tributaries of the Ahr include (in upstream order): Tributaries with a length of over 7 km (from source to mouth): Left tributaries are in dark blue; right tributaries in light blue. The Ahr is well known for the many vineyards that grace the hillsides downstream of the village of Altenahr . The small Ahr wine region

1400-614: 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

1450-594: 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),

1500-522: 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

1550-470: 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,

1600-414: 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

1650-569: The level of precipitation varies little and is evenly distributed over the year. Only 13% of weather stations record lower seasonal variations. The town was almost entirely submerged during the 2021 European floods . Altenahr was first mentioned in 893 in the Prüm Urbar . On 7 June 1969 the hitherto independent municipality of Kreuzberg, with its 560 inhabitants, was incorporated into Altenahr. The growth in Altenahr's population related to

1700-470: The municipality of Blankenheim, the Ahr reaches its southernmost point and enters the state of Rhineland-Palatine. From Müsch via Antweiler to Fuchshofen , the river runs northwards and turns east at Schuld heading through Insul to Dümpelfeld . Here, the Ahr collects the waters of the Adenauer Bach coming from the right and flowing in a northeasterly direction. In Altenahr, the valley bends to

1750-423: The narrowing and constraint of the riverbed. The course of the river was graded and its banks were stabilized. Catastrophic flash flooding occurred on the Ahr in 1910 and 2021 resulting in the deaths of hundreds. The Ahr rises in the middle of the village of Blankenheim , in the Eifel region of the German state of North Rhine-Westphalia , in the basement of a timber-framed house in an enclosed spring at

1800-459: 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

1850-538: The north: Kalenborn , Grafschaft , Mayschoß , Ahrbrück , Lind and Berg . The annual precipitation is 668 mm which is in the middle third of readings collected for Germany as a whole. 34% of weather stations of the German Meteorological Service record lower values. The driest month is February, the greatest amount of rain falls in July; 1.6 times that of February. However, in general

1900-769: 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

1950-480: 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

2000-419: 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

2050-529: 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

Its source is at an elevation of approximately 470 metres (1,540 ft) above sea level in Blankenheim in

2150-728: 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

2200-487: The south-facing slopes north of the river, particularly around the villages of Mayschoß , Rech , Dernau and Marienthal . The last narrow point in the Ahr valley occurs below the Bunte Kuh ("coloured cow"), a rock formation that almost reaches the river and leaves little room for road and railway. In Walporzheim , the valley widens abruptly, and the Ahr passes through the county town of Bad Neuenahr . In Heimersheim ,

2250-557: 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

2300-600: 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

2350-556: The vineyards end. The valley floor between Bad Bodendorf on the northern side and Sinzig on a terrace in the south is dominated by agriculture and fruit and vegetable growing. The mouth of the Ahr lies on the plain of the Golden Mile , between the Remagen district of Kripp and the town of Sinzig at a height of about 53 m above NHN . Since being re-naturalised (from 1979, see aerial photographs) it has been one of

2400-616: 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,

2450-502: 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

2500-482: 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
