It is connected with big gusset plate 5；Plate 3 is connect with big gusset plate 5 and trifle contact plate 6 by bolt 4 respectively；Oblique limb 2-1 and horizontal limb
2-2 is inserted into from the closed end of plate 3 and the neutral overlapping of axles of the neutral axis of oblique limb 2-1 and horizontal limb 2-2 and plate 3, oblique limb 2-1
And there are certain distance between the bolt hole on the end and plate 3 of horizontal limb 2-2, which will can guarantee the normal rotation of bolt
It twists.The width of oblique limb 2-1 and the slot on horizontal limb 2-2 is greater than plate thickness 0.1mm~1mm and avoids in order to construction and installation
Dimensional discrepancy, plate 3 are connect with oblique limb 2-1 and horizontal limb 2-2 by three side weld all arounds.Trifle contact plate 6, stiffener 7 are respectively at structure
Trestle 1 and big gusset plate 5 pass through welded connecting.Trifle contact plate 6, stiffener 7 pass through weldering respectively at truss column 1 and big gusset plate 5
The right angle connect in succession cuts a triangle and forms chamfering, come the residual stress for avoiding welding effect from supervening.Plate 3
It is connect respectively with big gusset plate 5 and trifle contact plate 6 by bolt 4, the number of bolt 4 and will be away from meeting load and construction is wanted
It asks, the distance between two web of plate is greater than thickness 0.1mm~1mm of trifle contact plate 6 or stiffener 7, to facilitate construction and installation.
Big gusset plate 5 and 6 aperture of trifle contact plate match with 3 aperture of plate.The diameter of aperture is straight according to the bolt that Force Calculation obtains
Big 0.1mm~the 1mm of diameter.Wherein, the size of weld seam is calculated according to National Standard of the People's Republic of China's " Steel Structural Design standard
GB50017-2017 " specified in weld seam Force Calculation.It is total that spacing, back gauge, size and the quantity of bolt hole meet the Chinese people
With state's national standard " Steel Structural Design standard GB50017-2017 ".It should be noted that position between oblique limb, horizontal limb and truss column,
Quantity and angle are according to practical implementation layout design.And the zoom of each scantling equal proportion.
It can be seen from the above, the utility model have it is following a little:
1, bending stiffness is reinforced in nodal plane, outside plane
The total bearing capacity of U-shaped double flute embedded steel board connecting node mainly by the pattern of connector and stiffness effect, compared to
Other 4 kinds of plate patterns effectively improve node by the method that ribbed stiffener is arranged in plate two sides using U-shaped double flute steel
Rigidity.4 ribbed stiffeners are equivalent to outside plane and increase the moment of inertia in section, and the moment of inertia in plane also increases.Therefore it improves
The bending stiffness of plate node.
2, ultimate bearing capacity of joints is improved since in the plate linked vector graph plane of the utility model, bending stiffness mentions outside plane
Height improves so the bearing capacity of entire node is opposite.
3, the stability enhancing of node
Node plate, column limb are respectively twin shaft multiaxis symmetrical section, effectively avoid the initial inclined of groove profile plate joint load
The heart, is not susceptible to torsional buckling, and stress performance excellent stability easily guarantees.
4, node connectivity can be good
Node is connected using bolt assembled, and Yi Genghuan detachable maintaining, easy for construction, the processing is simple, at low cost.
Groove profile, U-shaped node are respectively relative to by obtaining U-shaped double flute steel after large-scale finite element procedure ANSYS numerical simulation
Bearing capacity is as shown in table 1.
Table 1
It can be seen from the above, in the utility model nodal plane, outside plane, bending stiffness is reinforced；Ultimate bearing capacity of joints improves；Section
The stability enhancing of point；Node connectivity can be good.
Detailed description of the invention according to the present utility model the utility model is referred to.When reference example embodiment and this is described
