Corbel

As a console or Corbel (also Krage, rare bar, strength, support, art or Notstein ) is a designated from the wall outstanding, supporting lead in construction. On it, other components, such as cornices, arches, figures, columns, pilasters, balconies or beams may be placed. Depending on the location brackets can be a pure element design, a mere support member or a mixture of both.

Consoles in the architecture

Consoles are in architecture in addition to the function as a supporting element often a design element. They are usually executed in stone or masonry, wood truss spoken here of cleats. In more rare cases, they may also be made of wood and metal as a decorative plant also made ​​of baked clay, plaster, stone cardboard etc..

A tongue or anchor stone is a special form of the console where the lying in the wall part of the Konsolsteines is a dovetail configuration. This is a particularly force-locking connection to the brickwork, which prevents a sliding out of the stone.

Consoles are often decorated ornamental or figuratively. In the Romanesque architecture, they were often provided with grimaces, profanity, etc., which can have a demon or generally disastrous defensive ( apotropaic ) meaning the one hand, but on the other hand, can also be interpreted as drolleries or as craft gadgets. Since the late Renaissance, they are often designed as volutes.

Consoles in Tragwerksbau

Especially in high-rise buildings, factories and industrial buildings, as well as civil engineering consoles are used to initiate loads in a column or a wall. The insert is in there mostly functional reasons, the design aspect is in the background. The material is usually chosen according to the Surrounding supporting structure. Are usual steel and reinforced concrete. Typical applications for consoles are the seating of crane tracks for bridge cranes in warehouses and the connection of precast concrete products.

Brackets in reinforced concrete

In precast beams are usually executed as simply supported beams. In the continuous supports, the beam loads are applied on consoles. In order not to restrict the headroom under the console, the bars at supports notched according to the console size ( "separated supports "). For the design of consoles and remote supports the beam theory is no longer valid. The required reinforcement is normally designed using a truss model. Difficult is often useful to arrange the required reinforcement and also to anchor. For accurate load application bearings are arranged. For supporting concrete slabs also continuous strip consoles are arranged.

The production of reinforced concrete consoles takes place either simultaneously with the support or of the wall of which connects the console, or subsequently by means of starter bars.

Brackets in steel construction

Brackets in steel construction are in the simplest design brief profile steel pieces, such as from the I- or H- series. They are either welded to a top plate, and then fixed by a screw connection to a support, or directly welded to the latter.
