Form also occurs in succession, and up concave type tension string beam structure is exactly one of which structure type.But there is one kind in up concave type beam string
The defects of serious is unstable outside plane, and unstability outside plane easily occurs under the interference of construction process peace the curved beam.
Utility model content
Aiming at up concave type beam string destabilization problems outside strut plane easily occur for the purpose of this utility model, and provide one
Kind prevents the steel structure node of lateral bucking.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of steel structure node for preventing lateral bucking, for connecting strut and girder, the steel structure node includes two
Block lower ear plate, four pieces of upper ear plates and twice suspension cable, two pieces of lower ear plates are formed by two edges of a wing extension of strut I-steel,
Four pieces of upper ear plates are arranged at the one end being connected on girder with strut, and every piece of lower ear plate is respectively arranged at two pieces of upper ear plates
Between, a hinge assembly is formed, and two pieces of lower ear plates and four pieces of upper ear plates run through connection, the twice suspension cable by a bearing pin
It is respectively arranged at strut both sides.
The end plate welding of the lower ear plate and strut, upper ear plate and Main Girder Welding.
The end plate of the lower ear plate and strut realizes welding, the upper ear plate and master using the strong groove butt welding such as full penetration
Beam realizes welding using the strong groove butt welding such as full penetration.
An at least stiffener is set in the upper ear plate.
Multiple stiffeners are disposed with the strut and girder.
There is a gap between the lower ear plate and upper ear plate.
The gap width is 3~7mm.
A stiffener is at least connected between two hinge assemblies.
The girder is box-girder.
Compared with prior art, the utility model has advantages below：
(1) the utility model realizes twice defence line by six pieces of otic placodes and twice suspension cable, effectively prevents up concave type Zhang Xian
The outer unstability of plane occurs for beam, improves the Degree of Safety of structure；
(2) setting of six pieces of otic placodes of the utility model so that whole node has enough bendings resistance；
(3) multiple stiffeners are provided with the utility model node, effectively increase integrally-built intensity.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the sectional view at A-A in Fig. 1；
Fig. 3 is the corner displacement curve synoptic diagram of the utility model nodal finite element analysis.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with the utility model
Implemented premised on technical scheme, give detailed embodiment and specific operating process, but guarantor of the present utility model
Shield scope is not limited to following embodiments.
As Figure 1-Figure 2, the present embodiment provides a kind of steel structure node for preventing lateral bucking, for connecting beam string
Strut 1 and girder 2, steel structure node includes two pieces of lower ear plates, 3, four pieces of upper ear plates 4 and twice suspension cable, two pieces of lower ear plates 3
Formed by two edges of a wing extension of strut I-steel, four pieces of upper ear plates 4 are arranged at the one end being connected on girder 2 with strut 1, every piece
Lower ear plate 3 is respectively arranged between two pieces of upper ear plates 4, forms a hinge assembly, and two pieces of lower ear plates 3 and four pieces of upper ear plates 4 are logical
Cross a bearing pin 5 and be respectively arranged at the both sides of strut 1 through connection, twice suspension cable.The present embodiment middle girder is box-girder.
Above-mentioned node makes the defence line that there are beam string twice to ensure Outside-plate stabilizing.The first line of defence is that six pieces of otic placodes are formed
Two hinges, ensure that node can rotate along beam string direction, but vertical beam string direction forms couple, can resist strut and put down
Moment of flexure outside face during unstability, ensure beam string Outside-plate stabilizing.The twice suspension cable that second defence line is arranged for strut both sides, shape
Into rod-pulling type angle brace, it can prevent strut from unstability outside plane occurs by pulling force.
The end plate 6 of lower ear plate 3 and strut 1 is realized using the strong groove butt welding such as full penetration to be welded, upper ear plate 4 and girder 2
Welding is realized using the strong groove butt welding such as full penetration.
An at least stiffener is set in upper ear plate 3.Multiple stiffeners are disposed with strut 1 and girder 2.Stiffener includes thickness
Stiffener 7 and longitudinal stiffener 8.
In another embodiment of the present utility model, there is a gap between lower ear plate 3 and upper ear plate 4, gap width is 3~
7mm。
In another embodiment of the present utility model, a stiffener 9 is at least connected between two hinge assemblies.
Dedicated experiments and finite element analysis, the corner displacement curve that finite element analysis obtains are carried out for above-mentioned joint structure
Schematic diagram.There is enough bendings resistance from experiment and Finite element analysis results, the first line of defence, much larger than P- Δ effects
Caused strut upper end additional bending moment is 700x0.084=58.8kN*m, and second defence line prevents strut from existing as construction measure
Unstability under unexpected load action, increase the safety stock of structure.Above-mentioned joint structure can be effectively applied to up concave type beam string
In structure.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member makes many modifications and variations without creative work can according to design of the present utility model.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to design of the present utility model in domain
Available technical scheme is tested, all should be in the protection domain being defined in the patent claims.
