Embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
Please refer to Fig.1 and Fig. 2, the utility model steel structure column beam connecting node, including 1 He of beam connecting portion are shown in figure
Two column connecting portions 2, beam connecting portion 1 is up/down perforation concrete filled rectangular steel tube members, and every one side of beam connecting portion 1 is evenly equipped with six
Screw hole 11, the upper and lower ends of beam connecting portion 1 are welded with two column connecting portions 2 respectively；Column connecting portion 2 includes installing plate 21, connection
Part 22 and node end plate 23；The one side of installing plate 21 is welded in one end of beam connecting portion 1, the another side of installing plate 21 and company
One end welding of fitting 22, the other end of connector 22 are welded on node end plate 23, and four spiral shells are evenly equipped with node end plate 23
Hole 24；Connector 22 is the cross-shaped configuration being made of a steel plate 22a and two gusset 22b；Two gusset 22b are symmetrically welded
On the both sides of steel plate 22a.
The utility model can be prefabricated in the factory, during use by two styletable plate 3a of the column 3 of building correspondingly
It is mounted by means of bolts on two node end plates 23, the beam end plate 4a of the beam 4 of building is fixed on by bolt
On the side of rectangular steel pipe 1.
Embodiment 1
The steel plate thickness of connector 22 in the present embodiment is 12mm, and 23 thickness of node end plate is 16mm, and column section is
140mm × 6mm, nodes domains section are 140mm × 16mm.
Through styletable breaking test, peak level power 62.386F/kN, ultimate bending moment bearing capacity 27.512kN*m.
Embodiment 2
The steel plate thickness of connector 22 in the present embodiment is 12mm, and 23 thickness of node end plate is 12mm, and column section is
140mm × 6mm, nodes domains section are 140mm × 16mm.
Through styletable breaking test, peak level power 57.574F/kN, ultimate bending moment bearing capacity 25.390kN*m.
Embodiment 3
The steel plate thickness of connector 22 in the present embodiment is 14mm, and 23 thickness of node end plate is 16mm, and column section is
140mm × 6mm, nodes domains section are 140mm × 16mm.
Through styletable breaking test, peak level power 52.618F/kN, ultimate bending moment bearing capacity 23.205kN*m.
In the styletable breaking test of embodiment 1-3, by being continuously increased for horizontal force, the plate of 22 parallel direction of connector exists
Loading tension at initial stage increases essentially identical with compression side strain；Hereafter the side strain that is pressurized increase is fast compared with tension side, is loading
To ultimate bearing capacity 60% or so, the compression side of connector 22 is introduced into yield situation, and tension side is then surrendered.
The plate member edge strain of this 22 vertical force direction of rear connectors also enters plasticity also close to surrender, the at this time middle part of beam connecting portion 1, with
22 tension side weld seam tear of rear connectors destroys the bearing capacity that reaches capacity.The present invention can be seen that by above-described embodiment 1-3
Column beam connecting node ultimate bending moment bearing capacity in the range of 23~27kN*m.
Embodiment 4
Section HN200mm × 100mm × 6mm × 9mm of beam 4, nodes domains 140mm × 16mm, beam end plate 4a thickness
16mmm。
Pass through beam-ends breaking test, peak level power 64.962F/kN, ultimate bending moment bearing capacity 50.346kN*m.

In the beam-ends breaking test of embodiment 4-6, by being continuously increased for horizontal force, the strain of beam connecting portion 1 be pressurized with by
Drawing side strain size is almost equal, and direction is opposite；With the increase of horizontal force, open silk mouth bolt and produce sliding, then Bolt
Centre of form axis moves down, and compressive region area reduces, the increase of tensile region area.Due to the reduction of depth of compressive zone so that compressive region
Domain strain increase is very fast, and the strain being initially pressurized at the web of beam 4 is also by being gradually converted into tension.With first row bolt
Constantly it is drawn out, 4 compression one end edge of a wing of beam enters surrender, also reaches and surrenders with the web strain of the back rest 4.Pass through above-described embodiment
4-6 can be seen that the 1 ultimate bending moment bearing capacity of column beam connecting node beam connecting portion of the present invention is 50.346kN*m, level at this time
Shear as 64.962kN.
Above example is only for illustration of the utility model, rather than the limitation to the utility model, related technical field
Technical staff, in the case where not departing from the spirit and scope of the utility model, various conversion or modification can also be made, because
This all equivalent technical solution should also belong to the category of the utility model, should be limited by each claim.
