Center square steel tube is connected with end square steel tube by two pieces of parallel connecting plates, the connecting plate and center square steel of inside
The medial surface of pipe and end square steel tube is in same plane, the connecting plate in outside and the lateral surface of center square steel tube and end square steel tube
In same plane；
H profile steel beam is vertically fixed on the square steel tube of end, and the two sides of the flange plate of H profile steel beam are interior with end square steel tube
Lateral surface is fixedly installed stiffener inside and outside the square steel tube of end in same level, board ends of putting more energy into respectively with connection
Plate is fixedly connected with the flange plate of H profile steel beam.
Further, the height of connecting plate is greater than H profile steel depth of beam.
Further, stiffener includes two groups up and down to be parallel to each other.
Further, center square steel tube and end square steel tube composition " L " type, T-shape or cross-shaped configuration.
Further, connection board ends are welded to connect with center square steel tube and end square steel tube respectively.
Further, stiffener and end square steel tube, connecting plate and H profile steel beam are all made of welded connecting.
The invention has the following advantages:
(1) present invention can satisfy the shockproof requirements of strong column and weak beam, the weak component of strong node, will by connecting plate and stiffener
Center square steel tube, end square steel tube are connected together with H profile steel beam, and structural integrity is good, and the rigidity of structure is big, and joints more close
Reason, it is ensured that each point of limb column can cooperate, common stress；
(2) combining form of the present invention is versatile and flexible, and diversified forms can be arranged according to demand, such as " L " type, T-shape and ten
Font；
(3) present invention production construction is very convenient, and whole process is completed in factory, and scene need to only install i.e.
Can, construction period is substantially reduced, project cost has been saved.
