China's ancient building structure history is long, from imperial palace building in ancient times, temple palace, to residential building, uses Gu in a large number
Building timber structure form；Distributional region is extensive simultaneously, and almost throughout the whole nation, a lot of timber buildings have passed through centuries and even go up
The history of thousand, is the important component part of Chinese civilization, comprises abundant history culture intension.China have much gone through several
The ancient building of century-old even more than one thousand years, these ancient buildings are more remote owing to building the age, simultaneously because the feature of timber own, very
Many structures are urgently keeped in repair and reinforce.Ancient times, timber structure majority was Tenon node wood frame construction, and timber uses for a long time and is easily caused
Dry and cracked, rotten, damage by worms, the progressive damage such as aging, it is also desirable to safeguard and repair.And at the timber buildings of Modern New
In building course, the experience of the historic building structure of summarizing over, the building technology that the many of employing is novel in building course
And structure.But all of timber buildings all cannot avoid the shortcoming of the performance of timber own, so the reinforcing of timber structure and repairing

And minor diameter friction shim antivibrator.These devices the most also have corresponding defect, and such as, mild steel class dissipative member is
, there is service life short in expendable equipment, experience moderate finite deformation rear part itself i.e. occurs the shortcoming destroyed；Existing sector is rubbed
Wipe energy consumer, on the one hand due to connected mode existing defects, it is impossible to produce relative displacement along with the rotation of node and then can not
Friction energy-dissipating ability is provided；On the other hand, it is impossible to the size of frictional force is carried out manual control.Conventional friction type is consumed energy
Device, its frictional force that can be provided by is less, and there is also cannot the defect of artificial regulating friction force size simultaneously.
Therefore, for disadvantages described above, the present invention uses a kind of slideway knot that can produce and move with beam and mast axis direction
Structure, makes component and original structure form one slidably mechanism, and this dissipative member in use can follow the phase of beam column
The rotation centre of form that rotation changes component itself produces Relative friction slip, thus reaches the effect of friction energy-dissipating.Secondly, logical
Cross the bolt with spring of putting more energy into, utilize torque wrench can accurately control the size of frictional force in friction energy dissipation device, thus
Can reasonably design for different joint forms and arrange.
