Description
Technical field
A kind of semi-rigid bean column node friction energy consuming device of adjustable frictional force size is the utility model is related to, belongs to ancient
Build the construction such as timber structure, modern wood structure steel construction and reinforce repairerment field.Suitable for using structures with semi-rigid joints and pin joint
Building and structure.
Background technology
China's ancient building structure history is long, is built from ancient times imperial palace, temple palace, a large amount of using ancient to residential building
Build timber structure form；Simultaneously distributional region it is extensive, almost throughout the whole nation, many timber buildings have passed through centuries even on
The history of thousand, it is the important component of Chinese civilization, includes abundant history culture intension.China has much after several
The ancient building of century-old even more than one thousand years, these ancient buildings are more remote due to building the age, simultaneously because timber feature itself, very
More structures are urgently repaired and reinforced.Ancient times timber structure majority is Tenon node wood frame construction, and timber use for a long time is easily caused
It is dry and cracked, rotten, damage by worms, the progressive damage such as aging, it is also desirable to safeguarded and repaired.And in the timber buildings of Modern New
In building course, the experience for the historic building structure of summarizing over, many new building technologies used in building course
And structure.But all timber buildings can not all avoid the shortcomings that timber performance itself, so the reinforcing of timber structure and repairing
Mode of copying all is subject matter urgently to be resolved hurrily regardless of to historic building structure either modern wood structure.
Historic building structure bean column node mainly uses mortise-tenon joint mode, is broadly divided into dovetail and straight tenon connection side
Formula, it is typical varied rigid link.Its bearing capacity and bending rigidity are relatively low, and in use due to natural environment and ground
Easily because crimp produces the residual deformation that can not be automatically replied under shake effect, so that Tenon node produces loosening, and then
Cause it is integrally-built tilt askew sudden strain of a muscle, serious threat the service life of structure and safe to use, therefore Tenon node is structure
Weak location, typically by reinforcing joint with regard to the bearing capacity and anti-seismic performance of wooden frame can be effectively improved.
Among modern architecture and structure, people employ connected mode of the more multi-form node as structure, mixed
Among Xtah Crude Clay structure, steel construction, timber structure or mixed structure, structures with semi-rigid joints or pin joint all obtain greatly among structure
