For example, in building a house at home, in order to support the cantilever balcony, the cantilever short beam added under the balcony is the bracket. In the factory building, the legs on the column where the crane beam is placed are the supports.
The bracket is used to connect the cantilever beam and the hanging beam and transfer the load of the hanging beam.
Extended data
Brace is a common wooden component with special structure in ancient buildings in China. Generally, under the eaves, the upper end of a piece of wood is supported under the scissors, and the lower end is connected with the column, which directly transfers the weight of the eaves to the column. This kind of component is very common in ancient buildings in China, such as "bucket", "bracket" and "sparrow replacement".
Bracket setting
(1) In the first week of the house, the corbel is always attached to the cornice column, regardless of its structural support.
(2) The supports used in the main hall and the secondary hall will be different in shape and decoration. The support of the main hall is large, beautifully decorated, and the shape of the secondary hall is simple, even only using the support;
(3) Although the forms of brackets under the eaves of the same building are the same, the decorative contents are not exactly the same;
(4) Under the eaves of some temples in the south, we can see that a group of hats are added to the support, and a sitting bucket is placed on the top of the hat. Multi-layer brackets extend from the sitting bucket and support the eaves step by step, so the shape and decoration are naturally richer than that of a single bracket.
Niutui decoration theme
1, subject content
Themes include animals, plants, people and utensils, which can appear on a bracket alone or in combination with several themes. Some have formal beauty, such as rolling grass branches and plant flowers, and some have specific symbolic meanings, such as cranes symbolizing longevity, ancient ding, ancient bottles and other utensils symbolizing culture, pine, bamboo, plum, cold and three friends symbolizing people's noble morality, and lotus flowers are "out of the mud but not stained".
2. Theme combination
(1) The corbel is composed of curly grass lines, which are freely combined and have strong shape variability. The thick stem of curly grass can be directly rolled up and down into a triangle to form a bracket style, and even the end of the thick stem can be carved into a faucet to form a bracket formed by "grass dragon";
(2) The bracket is composed of palindromes, and the patterns with palindromes are called palindromes, which are free in form and suitable for various components, and can be turned up and down, left and right to form various shapes, also called "Kidnapper Dragon", which can directly form a triangular bracket like a grass-rolling pattern, but are mostly composed of palindromes, and animals, plants, figures, vessels and other contents are added;
(3) Cattle legs are composed of animal carcasses, as well as lions, deer and cranes. They are all carved on the brackets, which are more detailed than those carved on stilts;
(4) Parentheses with characters as the theme are the most complicated. There are literati warriors among the characters, some standing alone, some riding horses with hammers; More of a picture with a plot. The bearded birthday girl at the gate of the brain is old, holding a leading crutch in one hand and a big peach in the other. Under the guidance of bouncing children, she stands on the bull's leg with a smile, which is completely a group of woodcarving works of art;
(5) With the improvement of the wooden frame of the house, the eaves of the house are directly supported by the beams and columns protruding from the columns, and the role of the corbel in supporting the eaves gradually decreases, and the shallow relief on the surface of the corbel develops into deep relief or even through carving; A component under the eaves gradually evolved into a decorative art component in spring.
