Description
Technical field
The present invention relates to timber structure reinforcement technique fields, and in particular to a kind of ancient architecture wooden frame column mortise and tenon joint reinforcing device.
Background technology
The node of ancient architecture timber structure corrode and damage by worms and the effects that earthquake under occur to destroy post-reinforcing difficulty it is larger.When
After ancient architecture timber structure locally destroys, reinforcing installation cost is higher again for large area dismounting, and in displacement members or use
It necessarily changes to its initial condition when fiber reinforced, causes structure since new and old connection stiffness is inconsistent after often reinforcing
Twisting vibration, weaken the shock resistance of timber structure.At present, although there are the combined joints of steel-timber structure, due to Gu
It builds based on mortise and tenon node, mortise and tenon node connects originally as varied rigid link, and under geological process, damping energy dissipation performance table
It is now apparent.Existing steel-timber structure combined joint is mostly hinged joint or rigid joint, and be unable to control node rotation half is rigid
Property feature and damping effect, since its rigidity and periphery connection stiffness differ, can cause flatly after the completion of local stiffening
Torsional effect under shake effect.
Therefore it needs to provide a kind of new reinforcing device and method, ancient architecture wood can be reinforced in the case where reducing change
Its Stiffness Distribution is balanced while beam column mortise and tenon node part.

Steel node is crossed to connect with wooden frame, the steel node by steel node body, damper, beam connection, pin, stiffness tuning cushion block and every
Laminate is constituted, and the steel node body, beam connection carry out steel fourth of the twelve Earthly Branches dowel with pin, wooden frame respectively and connect, the beam connection
End far from wooden frame is hinged by pin and steel node body, and the beam connection is close to the upper and lower side in the end of steel node body
It is respectively equipped with stiffness tuning cushion block, two cushion blocks are fixed with steel node body head cover, interlayer board respectively, under the beam connection
End is additionally provided with damper between the side and steel node body of wooden frame, and the both ends of the damper are connect by otic placode with beam
Part, steel node body are hinged.
Further, the outside of the steel node is equipped with the exterior trimming parts for improving structural strength and aesthetics.
Further, the damper is hydraulic damper or air damper.
Further, the side plate of the beam connection offers several fixed holes.
Further, the steel node body is structure as a whole with interlayer board.
Further, the underlying space that the steel node body is located at interlayer board is pin join domain, is located at interlayer board
Superjacent air space be beam-to-column joint region.
The beneficial effects of the invention are as follows：
1, pass through the performance parameter of the size and damper of simple substitute stiffness tuning cushion block, you can to steel connection stiffness and
Damping characteristic is adjusted, and has not only completed reinforcing, but also so that overall structure does not generate or reduce torsional effect after reinforcing.
2, on the basis of controlling steel connection stiffness, damping characteristic, shorten original beam column using the addition of steel node
Length, the joint reinforcing being damaged for portion tip are extremely easy, it is only necessary to cut off end, then by steel node and beam column
It is connected, this greatly reduces reinforce difficulty so that does not need replacing beam column component in many cases in practice.
3, the assembled assembling that can also be used for newly-built timber structure, processes the wooden component and steel node in factory, and according to
Design needs to adjust the rigidity and damping characteristic of steel node, is assembled to scene.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
