Description
Technical field
The invention belongs to building structure fields, pacify more particularly, to a kind of ripple type braced frame node structure and its production
Dress method.
Background technique
Frame support structure is a kind of important structure type, and obtains the energy dissipating of more and more applications in China in recent years
Shock-damping structure is also mostly installed in frame structure in a manner of supporting connection.The connection with steel frame or concrete frame is supported to ask
Topic is that this structure type and energy-dissipating and shock-absorbing technology are able to the important leverage effectively to play a role.Existing research shows in beam column
Support node plate at node can have unfavorable additional stress to gusset plate since the opening and closing of beam column are acted on.Although existing
It studies trial and proposes calculation method with corresponding waiting model, but model is complex, and there are no fine for current specification
The considerations of this factor.Some scholars propose using certain construction way, so that release is in gusset plate and beam column junction
Tangential force is discharged, and then this opening and closing effect can not considered in calculating analysis, but leverage accuracy.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of ripple type support frames
Frame node structure and its fabrication and installation method.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of ripple type braced frame node structure, including ripple gusset plate and stiffener, the ripple gusset plate are wave
Line steel plate, the stiffener are equipped at least two, and at least two stiffener antisymmetry are connected on ripple gusset plate.
Further, the ripple heave direction of the ripple gusset plate is perpendicular to Impact direction.
Further, the dimple of the ripple gusset plate is zig-zag.
Further, the dimple of the ripple gusset plate is trigonometric function waveform.
Further, the ripple gusset plate is the square plate with a corner cut.
Further, the stiffener is vertical with ripple gusset plate connect.
Further, the stiffener and ripple gusset plate are welded to connect.
The present invention also provides the fabrication and installation methods of the ripple type braced frame node structure described in one kind, including walk as follows
It is rapid:
(a) ripple is processed on an integral plate；
(b) it is blocking that ripply integral plate cutting will be processed；
(c) to each piece of progress corner cut processing, ripple gusset plate is formed；
(d) stiffener is connected on the ripple gusset plate, forms final node structure；
(e) node structure is installed into braced frame.
Compared with prior art, the present invention have with following the utility model has the advantages that
1, the present invention uses ripple gusset plate, due to the characteristic of its ripple, has higher rigidity in one direction, carrying
Power is preferable with lateral stability, and very low in other direction rigidity and bearing capacity, can be released effectively beam column opening and closing effect and be drawn
The additional stress risen.
2, the ripple heave direction of ripple gusset plate of the present invention can effectively transmit support transmitting and come perpendicular to Impact direction
Axial force, the feature of ripple can effectively avoid additional stress caused by beam column opening and closing.
3, other connecting elements are not needed compared to relatively having the way for avoiding opening and closing effect, simple structure, just with construction.
4, the present invention can prevent unstability outside the face of gusset plate by the waveform of corrugated plating itself, save conventional node plate
For preventing the number of the stiffener of unstability.
