As a preferred version of the present utility model: the principal rod ring flat-plate is 2-3, and described a plurality of principal rod ring flat-plates are vertically arranged in parallel.
As a preferred version of the present utility model: the gluten ring flat-plate is 2, and described two gluten ring flat-plates are vertically arranged in parallel.
Principle of the present utility model is as follows:
Determine thickness, length, spacing and the weld seam requirement of ring flat-plate according to drawing requirement, ring flat-plate is connected with steel column by full penetration weld, after the steel column installation in position, principal rod, gluten are positioned on corresponding ring flat-plate, fix with fixture, the welder carries out two-sided welding, the measure such as temporary fixed of the cleaning of the in real time fixture of butt welded seam dismounting, welding slag and reinforcing bar after welding, guarantee that weld strength is not less than reinforcement yielding intensity, guarantees the construction quality of node.
The utlity model has simple in structure, easy construction, do not affect the stressed advantage of steel column.Steel column and crossbeam node are in the position of structure stress complexity, the quality of connection that guarantees this node is key and the emphasis that reaches designing requirement, the utility model makes the construction quality of reinforced concrete frame steel column and beam obtain good control, structure stress and designing requirement have been met, reduce cost and accelerated the duration, reduced workman's labour intensity.
