the end parts of the upper flange and the lower flange of the second steel beam on the butt joint side of the second steel beam extend outwards to form an upper connecting part and a lower connecting part, the inner side surfaces of the upper connecting part and the lower connecting part are provided with a first fixing groove and a second fixing groove for the embedding of the upper fixing plate and the lower fixing plate, so that the upper fixing plate and the lower fixing plate on the first steel beam are embedded in the first fixing groove and the second fixing groove of the upper connecting part and the lower connecting part of the second steel beam, and the tenon joint and the mortise joint are integrated with each other; a web plate on the butt joint side of the second steel beam is provided with a plurality of bolt holes;
and the splicing plate is connected with the web plate of the first steel beam butt joint side, the web plate of the supporting part and the web plate of the second steel beam butt joint side through bolts.
Preferably, the upper and lower fixing plates are parallel and respectively welded perpendicularly to upper and lower ends of the supporting portion extending outwardly from the web plate at the butt joint side of the first steel beam.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model discloses a design tenon fourth of twelve earthly branches node can guarantee to need not to weld in the construction of assembled steel construction, only needs to carry out bolted connection, can further reduce assembled steel construction period and construction cost.
