Description
Technical field
The present invention relates to a kind of timber structure beam column Tenon joint reinforcing restorative procedure.
Background technology
Timber structure exists in China's most area and is widely applied as a kind of ancient structure type.It is used as one kind
Construction material, timber has the characteristics of convenient material drawing, work progress are simple, speed of application is fast.However, the spy due to timber in itself
Point, after the use in one period is undergone, structural behaviour can degenerate, and particularly timber has a birth defect, such as knaur,
Damage by worms, it is rotten when, the degeneration of performance will become more apparent.In these performance degradations, the carrying of timber structure Tenon node
Power reduction is the degenerated form of a quasi-representative.The common Failure type of Tenon node, such as it is rotten, ftracture, pull out tenon, it will have a strong impact on
The shear behavior of the load-carrying properties of node, particularly node.
At present, the method for common timber structure Tenon joint reinforcing reparation mainly has：Directly Tenon node is consolidated by iron nail
It is fixed；Additional support is carried out to the position for pulling out tenon with angle steel or stub pole；Beam cross-section is wrapped with short steel, then will be flat with wooden peg
Steel is fixed on beam column；Beam body is laid down and changes beam again；With fibre-reinforced plastics（Fiber Reinforced
Plastics, FRP）Reinforcing wood beam.These methods can improve node bearing capacity to a certain extent, but these methods
There are still weak point, such as：Iron nail fixation will be damaged to structure in itself；Additional support method is held for node shearing resistance
Carry power and improve unobvious；Band steel method is high for the requirement of wooden peg, and complex manufacturing technology；Change beam method and destroy timber buildings sheet
The historical relic and historical value of body；Under the premise of FRP method for strengthening ftractures for timber structure, bearing power increase is not obvious, reduces structure
Ductility factor, FRP carries out grinding process for body surface requirement so that construction is complicated, and with the component after FRP reinforcings
Failure type is brittle break, is unfavorable for being formed the performance design principle of " the strong weak component of node ", and Seismic Behavior will drop
It is low.

Other welded flange plate, in vertical anchor ear towards the side anchor ear plate weld groove profile steel plate of horizontal anchor ear, is opened up on groove profile steel plate
Multiple holes corresponding with through hole on flanged plate；
（4）Wooden frame is lifted by jack, the tenon of wooden frame is extracted after the excision of the fourth of the twelve Earthly Branches of pin mouthful；
（5）Horizontal anchor ear and vertical anchor ear are installed, horizontal anchor ear is held tightly in the precalculated position at wooden frame tenon end, will be vertical
Anchor ear is held tightly in the precalculated position of the pin fourth of the twelve Earthly Branches mouthful section；
（6）Using multiple elastic thread fastener assemblies through the corresponding hole on groove profile steel plate and with the phase on flanged plate
Answer after through hole, horizontal anchor ear is connected to form cooperative entirety with vertical anchor ear；
（7）Shed jack.
In further preferred scheme, step（2）Two anchor ears are designed according to beam column range size to be reinforced respectively
Length, it is ensured that the length range can play anti-shearing consolidation effect；Surveyed respectively according to the shape of beam column and scene are actual
The sectional dimension of amount design beam column component surface should be carried out before the shape and size of two anchor ears, measurement sectional dimension repairing and
Chipping processing.
In further preferred scheme, step（3）In horizontal anchor ear and vertical anchor ear comprising two anchor ear plates and
At least one threaded fastener component, the anchor ear plate is constituted by the wing plate of middle hoop plate and both sides, and the wing plate is opened up
There are at least one connecting hole, the wing plate of two anchor ear plates mutually to be embraced after passing through corresponding connecting hole by threaded fastener component
Tightly.
In further preferred scheme, the wing plate is molded or is integrally formed with hoop plate weld.
In further preferred scheme, the hoop plate is in circular arc or bent.
In further preferred scheme, the threaded fastener component includes screw and nut, the screw and nut
Immovable fitting.
In further preferred scheme, step（4）In excision tenon after wooden frame section should be surface-treated, its
Include erodable section processing and the processing of surface chipping, wooden frame section requires smooth without local crowning after processing.
In further preferred scheme, step（6）In elastic thread fastener assembly include spring, screw and spiral shell
Mother, the spring is set on screw and is located between groove profile steel plate and flanged plate, the screw and nut immovable fitting.
In further preferred scheme, the screw is bolt, screw rod or studs.
Compared with prior art, the invention has the advantages that：Using the construction technology for not falling frame, wood is both overcome
Structural construction is the problem of Tenon connection stiffness declines under long-term natural environment, it also avoid during repairing construction to log
Structural damage, while improving the energy dissipation capacity of Tenon node under geological process again, and need not change wood structures, apply
Work is easy, and reinforcing expense is low, broad covered area, and significantly, ductility of joint is significantly improved consolidation effect.
