Description
Technical field
The present invention relates to a kind of ancient building of device shape-memory alloy wire and modern wood structure Tenon node, belong to ancient architecture
Build timber structure and modern wood structure reinforcement protection, quake evaluation field.It is adapted to tradition timber structure and modern wood structure quake evaluation
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, 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 is used mostly
Steel fastener is connected or part is using the connection of Tenon node, but connects weaker, and its bending rigidity is smaller, belongs to varied rigid link.
The joint structure mode of above-mentioned timber structure causes the overall anti-side rigidity deficiency of gallows timber, 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 that the integer dynamical response to reduce gallows timber and limitation storey sidesway are reinforced to Tenon node
The emphasis of structure strengthening by reparative method.
Existing common timber structure Tenon joint reinforcing material has a lot, such as 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 and energy-dissipating property of node, but the bending rigidity of Tenon node can be significantly increased so that total
Rigidity increase, its seismic response is increased considerably, and is unfavorable for antidetonation；On the other hand, the traditional material such as steel plate, angle steel, dog is long
Phase exposure such as is easier to get rusty in atmosphere, corrode the endurance issues, and latent potential safety hazard simultaneously influences to build 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
It itself can produce larger residual deformation, it is impossible to return to original state, 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, with 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
Improve the anti-bending bearing capacity and bending rigidity of Tenon node, it is impossible to improve its shear-carrying capacity；In addition, carbon cloth fragility is strong,
Ductility is poor, and the purpose that Tenon node does not reach raising node energy dissipation capacity is reinforced with it；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 or high-temperature condition, it is impossible to continue to make
With.
Therefore, it is necessary to be carried out using a kind of novel intelligent material to historic building structure and modern wood structure Tenon node
Consolidation process, marmem is a kind of new function material with a variety of special mechanical properties, with significant shape
Memory effect, phase transformation super-elasticity and high damping characteristic.Compared compared with other materials, the anti-fatigue performance of marmem is fine,
Deform recoverable strain very big (6%~8%).Therefore, reinforced using marmem, compared with the reinforcing side of other materials
Method is compared, the characteristics of being automatically replied with deformation, has higher damping energy dissipation ability again, is to mitigate building structure in earthquake
Effect is lower to be damaged, and reduces and structure is repaired after earthquake in itself or the effective scheme of reinforcement material expense is repaired, changes.
The content of the invention
To solve defect or deficiency present in background above technology, it is an object of the invention to propose a kind of device shape
The ancient building and modern wood structure Tenon node of memory alloy wire, are solved " super present in existing Tenon joint reinforcing mode
Just ", the problems such as poor durability, residual deformation are big, fire resistance is poor.The Tenon node is carried out using austenite shape memory alloy silk
Reinforce, in the case where being not apparent from improving Tenon node bending rigidity, energy dissipation capacity, the endurance quality of node is greatly improved
And fire resistance, and can realize it is integrally-built after deformation automatically reset, and then improve the elder generation of Tenon node automatic recovery ability difference
Its defect.So as to solve building inclination caused by the dynamic response because of earthquake, wind shake or mechanical oscillation generation, collapse
Problem, and avoid the secondary correcting and then reinforcing after building shake.
The present invention is realized by following technical proposals.
