Description
Technical field
The present invention relates to building structure technology fields, more particularly, to a kind of slide hinged node and design method.
Background technique
In general, in the metal structure of architectural engineering, for considering slide hinged node, sliding bearing can be passed through
Node, rocker arm node or slotted hole node.Sliding bearing node is high to material hardness requirement, and construction is complicated, needs finely to add
Work, cost are more expensive；It is relatively simple on rocker arm joint form, but Out-of-plane Stability is bad, and it is big to take up space, it is not beautiful enough.
Traditionally it is practical it is more be slotted hole node, i.e., the round pin shaft hole on otic placode is lengthened as slotted hole, turns node
There is slipping space while dynamic, this way is most simple economy.But slotted hole has a defect, i.e., the round hole with straight line
It is theoretically infinitesimal line contact between wall, ideally can not theoretically transmits any pressure.Stress in material rises
It is just infinity, the transmitting of pressure is just transmitted by forming face contact after deforming between pin shaft and hole wall.It is this
Mechanism makes the contact position of pin shaft and otic placode be easy to be plastically deformed, and micro destruction occurs, when transverse pressure is big
It waits, plastic deformation may directly result in node and lose sliding ability；And transverse pressure it is small when, micro plastic deformation can also
Can accumulate over a long period causes considerable accumulative deformation to generate security risk.
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 slide hinged nodes
And its design method.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of slide hinged node for the hinged joint of hinged first connector and the second connector, including is fixed on
Two to be parallel to each other piece otic placode on first connector, and it is fixed on the pivot pin of the second connector two sides, two pieces of otic placodes
Upper to offer sliding slot respectively, the pivot pin slides in sliding slot.
Further, the section of the pivot pin is round rectangle.
Further, first connector and the second connector are respectively the building components such as beam, column, support or keel.
Further, the pivot pin and sliding slot, which have, relatively rotates.
Further, the size of the pivot pin meets:
It is assumed that the smooth no concave-convex of contact surface, the then direct stress calculated are
Force of sliding friction size is f=μ N
For metal material, intensity takes Von-Mises stress, considers that shearing stress and direct stress meet effect,
Critical moment before sliding, the shear stress in material are
It is complex as Von-Mises stress jointly with direct stress,
Wherein, μ-slip friction factor, N- maximum pressure, the length in a- pivot pin section, r- pivot pin section round rectangle
Chamfer radius, the thickness of t- otic placode, fdStrength of Metallic Materials design value.
Above formula ensure that metal will not be destroyed because of sliding is squeezed.
Further, the size of the pivot pin (5) meets:
For extreme case, that is, in the case where squeezing, slide and rotating simultaneously, metal will not enter plasticity, then
It needs to guarantee
This correspondence extruding force is very big, so that the case where pin shaft and otic placode come into full contact with, and it is worst to metal strength
Situation.
Further, the size of the pivot pin (5) meets:
For it can happen that being that pressure N is not very greatly, pin shaft can't come into full contact with otic placode at this time, but require
Rotation space it is bigger.Guarantee there is sufficiently rotation gap to be unlikely to block, needs to guarantee
A θ < B-b
Wherein: the length in a- pivot pin section, the width in b- pivot pin section, the width of B- sliding slot, the length of L- sliding slot, θ-axis
Sell the corner in sliding slot.
Further, the size of the pivot pin (5) meets:
Guarantee sufficient flexible slippage, that is, meets
a+x++x-≤L
Wherein: the length in a- pivot pin section, the width in b- pivot pin section, the width of B- sliding slot, x+Sliding slot is arrived on the left of pivot pin
The distance of left edge, x-The distance of sliding slot right hand edge, the length of L- sliding slot, corner of the θ-pivot pin in sliding slot are arrived on the right side of pivot pin.
A kind of slide hinged structure, including the first connector, the second connector and above-mentioned slide hinged node.
Compared with prior art, the invention has the following advantages:
1, slotted hole pin shaft node is compared, contact stress is small between pin shaft and pin shaft hole wall of the present invention, and material property plays
Sufficiently, there is higher lateral bearing capacity.
2, slotted hole pin shaft node is compared, the present invention is more durable, is not susceptible to be plastically deformed or destroy.
3, sliding bearing node and rocker arm node are compared, the processing is simple, economical and practical by the present invention.
4, rocker arm node is compared, the present invention is small in size, will not excessively occupy space or influence appearance.
