The problems such as formula all respectively has its own feature, but it is not high often to appoint that there are bonding strengths, and anti-seismic performance is bad, and construction is complicated, and
As the scale of steel construction is increasing, steel truss roof span is also increasing, and therefore steel truss also becomes increasingly complex, herein
Under background, it is necessary to which a kind of intensity is high, and ductility is good, the good branch pipe connection type of anti-seismic performance.
Utility model content
Purpose of utility model: the utility model discloses a kind of hemispherical flanged joint steel truss connecting node, each branch pipes
Linkage section is that arc flange is bolted jointly on the same hemispherical steel plate, and connecting each steel truss branch pipe using this kind can have
Improve the anti-seismic performance and whole ductility of steel truss entirety in effect ground.
Technical solution: a kind of hemispherical flanged joint steel truss connecting node, including steel pipe branch pipe, high-strength bolt, half
Spherical steel plate.
Wherein, steel pipe branch pipe connect one end with hemispherical steel plate and is provided with cambered surface flange；The cambered surface flange and hemispherical steel
Plate fits, and is provided with one-to-one bolt hole on cambered surface flange and hemispherical steel plate；High-strength bolt passes through the bolt
Hole fastens to be connected and fixed steel pipe branch pipe and hemispherical steel plate by nut.
Hemispherical steel plate is worn in order to prevent, and spacer for bolt, bolt are equipped between nut and hemisphere shape steel plate inner sidewall
Gasket is bonded with hemisphere shape steel plate inner sidewall.
Cambered surface flange welding is provided with reinforcing rib between cambered surface flange and steel pipe branch pipe on steel pipe branch pipe, with enhancing
Bonding strength between cambered surface flange and steel pipe branch pipe.
Cambered surface flange and hemispherical steel plate unbalance stress cause stress to be concentrated in order to prevent or material deforms, bolt hole pair
Title is set to steel pipe branch pipe two sides.
In order to guarantee that the intensity of hemispherical steel plate is able to satisfy practical application request, the thickness of hemispherical steel plate is not less than
3cm。
During installation, due to needing to correspond the bolt hole on the bolt hole and hemispherical steel plate on cambered surface flange
Being relatively difficult, and need to guarantee that the alignment of other holes is tightened during the installation process, when bolt is tightened, this process right and wrong
Often difficult, therefore the hole wall of the bolt hole opened up on cambered surface flange extends outward to form hole pipe, the outer tube diameter of the hole pipe is equal to
The aperture for the bolt hole being correspondingly arranged on hemispherical steel plate.When needing to install steel pipe branch pipe, it is only necessary to which hole pipe is inserted into hemisphere
In the bolt hole being arranged on shape steel plate, so that it may guarantee that the hole on cambered surface flange and hemispherical steel plate is one-to-one, bolt
It across bolt hole, is fastened, steel pipe branch pipe and hemispherical steel plate can be connected and fixed using nut.
The utility model has the advantages that (1) uses high-strength bolt connecting branch instead of welded connecting, avoids and produced during welding procedure
Raw residual stress and residual deformation plays a kind of protecting effect to the intensity of structure itself, and uses the high-strength spiral shell of friction-type
Bolt also improves the effect that overall structure bears dynamic load while improving the intensity of connecting node, improves the anti-of structure
Shock stability；
(2) since large-scale steel construction is universal using increasingly coming under construction, steel truss also becomes increasingly complex, therefore uses
The hemispherical steel plate replaces traditional welded connecting under the premise of guarantee bonding strength is with convenient construction, can be more
Connecting branch on more directions, the problem of having well solved branch pipe complexity complexity in steel truss；
(3) also facilitate construction using the structural inspection in this hemispherical flange form node connection type later period and reinforcing.
It can play the role of reinforcing entire node in branch pipe welded directly to the run pipe and hemispherical steel plate when necessary.

Specific embodiment
As shown in Figure 1, a kind of hemispherical flanged joint steel truss connecting node disclosed by the utility model: including: the company of need
The steel pipe branch pipe 1 connect, friction type high strength bolt 2, the hemispherical steel plate 3 in strap bolt hole, the cambered surface flange 4 of steel pipe connecting pin,
Spacer for bolt 5, steel pipe branch pipe 1 are connected on hemispherical steel plate 3 by high-strength bolt 2.
As shown in Figures 2 and 3, wherein steel pipe branch pipe 1 connect one end with hemispherical steel plate 3 and is provided with cambered surface flange 4；Cambered surface
Flange 4 fits with hemispherical steel plate 3, is provided with one-to-one bolt hole on cambered surface flange 4 and hemispherical steel plate 3；It is high-strength
