Described upper connector comprises coupling part, top flange and web coupling part, and described web coupling part is vertically set on the center line of coupling part, top flange, and both form T-shaped.
The connection cross section of described node area H section steel beam Duan Zaiyu web coupling part is inverted T shape, and the cross section of remainder is the H type.
The web of the height of described web coupling part and node area H section steel beam section is contour.
Described lower connector comprises lower flange of girder edge coupling part and post coupling part, and described post coupling part is vertically set on the end of lower flange of girder edge coupling part, and both form L-type.
But have the slotted hole of connector under up-down adjustment on described post coupling part.
Be provided with stiffener on the axis of the angle between described lower flange of girder edge coupling part and post coupling part.
Compared with prior art the utlity model has following characteristics and beneficial effect:
at first, compare with existing full bolt joint, the upper connector of variable deck-molding assembling type node described in the utility model and lower connector be the top flange by high-strength bolt and girder connection section respectively, the bottom flange of web and post node section and girder connection section, make node have rotational stiffness preferably, and can transmit reliably the H section steel beam, shearing between quadrate steel pipe column, moment of flexure, in construction, can be with the node junction plate after factory be welded to the quadrate steel pipe column relevant position, then directly with high-strength bolt, the H section steel beam is connected with quadrate steel pipe column to the scene, do not need Site Welding, difficulty of construction and cost have been reduced.
Secondly, because the connector of position of joints in the utility model is set to independently upper connector and lower connector, so same connector can adapt to the requirement of different beam section sizes to connecting, improved the versatility of connected node.
Moreover, can realize on the construction location of girder steel and lower connector having reduced the requirement for member processing and construction precision by adopting Long Circle adjusting bolt hole by beam top flange junction plate during construction, reduced difficulty of construction, improved efficiency of construction.
The H section steel beam that the utility model can be widely used in having in steel work multiple deck-molding is connected connection with quadrate steel pipe column.
