Diagram of a bull leg column

A bull leg is an outcropping structure, for example, when building a house in your own home, the short overhanging beams that are added at the ground level of a balcony in order to support an outcropping balcony are bull legs. There are also factory buildings, columns in order to set aside crane beams and other external pickups is the bull's-eye.

Often independent of the bull's-eye belongs to the beam (build your own house), if cast-in-place with the plate can be counted in the plate, and the column connected to the column counted in the column. The former has been rarely used in large buildings, are used in other and cast-in-place structure of the whole casting, the latter in the plant in a large number of references.

In ancient architecture, the bull's-eye and the sparrow is a similar component but not identical. The sparrow for the wood located between the column and the beam, it can play the role of inheritance force, but also can play a decorative role. It is equivalent to the axillary part of the concrete axillary beam in modern architecture.

Bull's leg is also called "horse's leg",

also refers to a short piece of wood sticking out from the column, which generally only plays a decorative role and does not play the role of inheritance. But in some places and some information, the cow leg and the bird for the two are mixed.
