Description
Technical field
The ancient building and modern wood structure Tenon node of a kind of device shape-memory alloy wire are the utility model is related to, is belonged to
Historic building structure and modern wood structure reinforcement protection, quake evaluation field.It is adapted to traditional timber structure and modern wood structure antidetonation
Mitigation demand.
Background technology
Wooden Structure of Chinese Ancient Architecture is with a long history, nationwide, and the tradition for containing preciousness builds skill and building
Culture.Existing ancient building has Beijing's Imperial Palace, Shanxi Wooden Pagoda at Yingxian County, Chengde Mountain Resort, Ji County Monastety of Solitary Happiness etc..Ancient building wood knot
Structure beam-to-column joint mode is mainly mortise-tenon joint, i.e., beam-ends makes tenon form, and styletable makes fourth of the twelve Earthly Branches degree of lip-rounding formula.Mortise-tenon joint has
The effect coupled hardness with softness, it is typical varied rigid link.Under such as earthquake, wind action, Tenon node occurs extruding and become
Shape, tenon, which loosens, even to be extracted, its by it is curved, cut, the basic bearing capacity decrease such as turn round.Modern wood structure connected mode uses mostly
Steel fastener is connected or part is connected using Tenon node, but connection is weaker, and its bending rigidity is smaller, belongs to varied rigid link.
The joint structure mode of above-mentioned timber structure causes gallows timber entirety anti-side rigidity deficiency, makees in dynamic loads such as earthquake, beam wind
Under, overall structure easily produces stronger dynamic response and larger storey sidesway, so as to cause structure subject to severe risks of damage
Even collapse.Therefore, it is wood Tenon node to be reinforced to reduce the integer dynamical response of gallows timber and limitation storey sidesway
The emphasis of structure strengthening by reparative method.
Existing common timber structure Tenon joint reinforcing material has a lot, for example, the traditional material such as steel plate, angle steel, dog and
The new materials such as mild steel, carbon fiber.On the one hand, although the traditional material such as steel plate, angle steel, dog reinforcing timber structure Tenon node can
To improve the bearing capacity of node and energy-dissipating property, but the bending rigidity of Tenon node can be significantly increased so that total
Rigidity increase, its seismic response increase considerably, and are unfavorable for antidetonation;On the other hand, the traditional material such as steel plate, angle steel, dog is grown
Phase exposure such as is easier to get rusty in atmosphere, corrode the endurance issues, and potential safety hazard of hiding and influenceing is built attractive in appearance;Furthermore
Because the materials such as steel plate, angle steel, dog, mild steel belong to elastic-plastic material, structure is after big geological process is undergone, these materials
Itself larger residual deformation can be produced, original state can not be returned to, it is necessary to change reinforcement material, secondary add is carried out to structure
Gu.Carbon cloth is a kind of unidirectional carbon reinforcing product, has stronger tensile bearing capacity, but because material can only be held in itself
By pulling force, the shear-carrying capacity in its vertical fibers direction is almost nil, therefore, using carbon cloth reinforced Tenon node, is only capable of
The anti-bending bearing capacity and bending rigidity of Tenon node are improved, its shear-carrying capacity can not be improved;In addition, carbon cloth fragility is strong,
Ductility is poor, and the purpose for improving node energy dissipation capacity is not reached with its reinforcing Tenon node;In addition, carbon cloth and its Binder Course category
In inflammable thing, its fire resistance extreme difference, burning or gross distortion easily occur under naked light either high-temperature condition, it is impossible to continue to make
With.
Therefore, it is necessary to historic building structure and modern wood structure Tenon node are carried out using a kind of novel intelligent material
Consolidation process, marmem are a kind of new function materials with a variety of special mechanical properties, have significant shape
Memory effect, phase transformation super-elasticity and high damping characteristic.To be compared compared with other materials, the anti-fatigue performance of marmem is fine,
It is very big (6%~8%) to deform recoverable strain.Therefore, reinforced using marmem, compared with the reinforcing side of other materials
Method is compared, and has the characteristics of deformation can automatically reply, has higher damping energy dissipation ability again, is to mitigate building structure in earthquake
Damaged under effect, repair structure in itself after reducing earthquake or repair, the effective scheme of replacing reinforcement material expense.
Utility model content

The ancient building and modern wood structure Tenon node of shape-memory alloy wire, are solved present in existing Tenon joint reinforcing mode
" super firm ", poor durability, the problems such as residual deformation is big, fire resistance is poor.The Tenon node uses austenite shape memory alloy silk
Reinforced, in the case where being not apparent from improving Tenon node bending rigidity, the energy dissipation capacity, durable of node is greatly improved
Performance and fire resistance, and can realize deformation after it is integrally-built automatically reset, and then improve Tenon node automatic recovery ability it is poor
Birth defect.So as to solve the building inclination caused by dynamic response caused by earthquake, wind shake or mechanical oscillation, fall
The problems such as collapsing, and avoid the secondary correcting and then reinforcing after building shake.
The utility model is realized by following technical proposals.
