Timber structure and modern wood structure reinforce repairerment field.Suitable for building for traditional wood-structure old building and modern wood structure bean column node
It makes reinforcing and repairs demand.
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 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 are reinforced.Ancient times timber structure majority is Tenon node wood frame construction, and timber use for a long time is easily led to
It is dry and cracked, rotten, damage by worms, the progressive damages 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 novel 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 main problem urgently to be resolved hurrily regardless of to historic building structure either modern wood structure.
For ancient times timber buildings, the history contained for History of conservancy timber buildings, historical relic, art and science valency
Value, the maintenance and reinforcement of timber buildings can not possibly largely replace green wood, for Tenon node wooden frame, weak location
At Tenon node, generally by reinforcing joint with regard to the bearing capacity and shock resistance of wooden frame can be effectively improved.

The rigidity of structure is difficult to play a role in terms of energy consumption.Furthermore since the materials such as angle steel, steel plate, reinforcing bar, cramp iron belong to bullet modeling
Property material, for structure after big geological process is undergone, these materials can generate larger residual deformation in itself, can not be restored to just
Beginning state.
Occurred some novel node energy-consumption devices in recent years, such as mild steel reinforces energy-consuming device, fan-shaped friction energy dissipation device
And minor diameter friction shim damper.These devices also have the defects of corresponding in use, for example, mild steel class dissipative member is
Expendable equipment, short there are service life, experience moderate finite deformation rear part is the shortcomings that destruction in itself；Existing sector is rubbed
Energy consumer is wiped, on the one hand due to connection mode existing defects, it is impossible to generate relative displacement with the rotation of node and then cannot
Friction energy-dissipating ability is provided；On the other hand, the size of frictional force can not artificially be controlled.It consumes energy for conventional friction type
Device, can be provided that friction is small, at the same there is also can not artificially regulating friction force size the defects of.
Therefore, for disadvantages described above, the present invention is using a kind of slideway knot that can be generated with beam and the movement of mast axis direction
Structure makes component form a kind of slidable mechanism with original structure, which can follow the phase of beam column in use
Change the rotation centre of form of component in itself to rotation and generate relative friction slip, so as to achieve the effect that friction energy-dissipating.Secondly, lead to
The bolt with spring of putting more energy into is crossed, the size of frictional force in friction energy dissipation device can be accurately controlled using torque wrench, so as to
Different joint forms can be directed to, reasonably design and arrange.
