Description
Technical field
The present invention relates to a kind of steel structure node, the steel structure node of lateral bucking is prevented more particularly, to a kind of.
Background technology
With the development and the progress of Building technology of society, requirement of the people to building has been not only the base for meeting existence
The need for this demand and production, and have higher level requirement to building --- beautiful design, it is economical and practical, across bigger
Space, corresponding structure develops towards the integrated direction of lightness, single-layered and building structure, the structure that can not possibly be used originally
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
Serious defect is unstable outside plane, easily occurs unstability outside plane under the peaceful the curved beam interference of construction process.
The content of the invention
Aiming at up concave type beam string destabilization problems outside strut plane easily occur for the purpose of the present invention, and provide a kind of anti-
The only steel structure node of lateral bucking.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of to prevent the steel structure node of 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 present invention has advantages below：
(1) present invention realizes twice defence line by six pieces of otic placodes and twice suspension cable, effectively prevents that up concave type beam string from sending out
Unstability outside life face, improves the Degree of Safety of structure；
(2) setting of six pieces of otic placodes of the invention so that whole node has enough bendings resistance；
(3) multiple stiffeners are provided with node of the present invention, effectively increase integrally-built intensity.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is the sectional view at A-A in Fig. 1；
Fig. 3 is the corner displacement curve synoptic diagram that nodal finite element of the present invention is analyzed.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to
Following embodiments.
As Figure 1-Figure 2, the present embodiment offer is a kind of prevents the steel structure node of lateral bucking, for connecting beam string
Strut 1 and girder 2, steel structure node include 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 lead to
A bearing pin 5 is crossed through connection, twice suspension cable is respectively arranged at the both sides of strut 1.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 formed for six pieces of otic placodes
Two hinges, it is ensured that node can be rotated along beam string direction, but vertical beam string direction forms couple, can be resisted strut and be put down
Moment of flexure outside face during unstability, it is ensured that beam string Outside-plate stabilizing.Second defence line is the twice suspension cable that strut both sides are arranged, shape
Into rod-pulling type angle brace, it can prevent that strut from occurring unstability outside plane by pulling force.
The end plate 6 of lower ear plate 3 and strut 1 is welded using the strong groove butt welding realization such as full penetration, 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 invention, 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 invention, 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 is obtained are carried out for above-mentioned joint structure
Schematic diagram.From experiment and Finite element analysis results, the first line of defence has enough bendings resistance, much larger than P- Δ effects
Caused strut upper end additional bending moment is 700x0.084=58.8kN*m, and second defence line prevents that strut from existing as construction measure
Unstability under unexpected load action, increases 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 invention described in detail above.It should be appreciated that one of ordinary skill in the art without
Need creative work just can make many modifications and variations according to the design of the present invention.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, all should be in the protection domain being defined in the patent claims.
