Description
Technical field
A kind of light section roof purline system is the utility model is related to, more particularly, to a kind of angle brace tie rod as purlin branch
The light-steel roofing system of point, can be widely applied in the roof purline system of light Steel-Structure Factory with Steel.
Background technology
In light Steel-Structure Factory with Steel, whole building is made up of structural system and retaining design.Structural system is by portal-rigid frames, facade
Support, roofing system composition, form a firm framework.Retaining design is by roofing system and metope system group
Into being attached in structural system, form the complete light-type steel structural workshop met using function.
In roofing enclosure system, mainly it is made up of purlin, angle brace, tie rod, roof boarding.Roof boarding self threading pin or fixation
Seat is fixed on purlin, and purlin is fixed on portal-rigid frames by purlin support, and tie rod is at a certain distance from ridge by each purlin drawknot
Get up, angle brace connects the lower flange of portal-rigid frames crossbeam with purlin.
The effect of purlin is effectively to be delivered to the load of roof boarding on portal-rigid frames, and purlin needs preferable bending resistance
Intensity, rigidity and stability.Purlin typically uses Z-type or c-type light gauge cold-formed steel shape, and in-plane strength, rigidity, stability are by girder steel
Span determine.Because the Out-of Plane Stiffness of purlin is weaker, a few road tie rods are set often through along the span direction of purlin, to provide
The out of plane constraint of purlin, reduce computational length outside the face of purlin, to ensure the lateral stability of purlin.
In actual applications, tie rod is often subsection setup, in order to be linked and packed conveniently, the axis of two neighboring tie rod
Not point-blank, but it is connected on purlin on two bolts hole at regular intervals.Two neighboring tie rod axle power
Eccentric locally to produce a moment of flexure for purlin, purlin is under the Moment, and because purlin wall thickness is very thin, rigidity is very weak, very
Easily form local torsion's deformation.The axial displacement of tie rod can be so caused, causes tie rod to relax, it is impossible to be carried well for purlin
For face outer support rigidity, it is impossible to computational length outside the effective face for reducing purlin.
The effect of angle brace is to connect purlin and portal-rigid frames crossbeam, forms triangle robust structure.Such purlin
Support can be provided for portal-rigid frames crossbeam by angle brace, avoid unstability outside the face of portal-rigid frames crossbeam, it is horizontal to reduce portal-rigid frames
Computational length outside the face of beam.Meanwhile portal-rigid frames crossbeam can also provide support by angle brace for purlin, reduce the effective of purlin
Computational length.
In actual applications, purlin and angle brace junction, outside the gore that angle brace, purlin are formed it is not any about
Beam, tie rod is typically not provided with herein, this is easy for making purlin have certain unstability displacement outside face, reduces angle brace to purlin
Supporting role, the computational length reduction to purlin, it is impossible to play useful effect.
Based on above technical background, it is necessary to carry out structural system optimization to angle brace, purlin, portal-rigid frames transverse beam system, carry
High tie rod and the rigidity of purlin junction, and the mutual cooperative bearing relation of angle brace, purlin and tie rod three are made full use of, strengthen
The globality of roof purline system, spatial cooperation stress performance is played, roofing steel using amount can be saved, there is larger economic performance.
