In combined steel and concrete column, the form of reinforcing bar is divided into two kinds of real abdomen formula and open web types basically.Commonplace in the wherein real abdomen formula combined steel and concrete column is the mode that cross-shaped steel is set in post, and reinforcing bar is welded by the steel plate that does not have the hole, also can be made up of H steel or i iron.Though this form of structure can improve the ductility and the bearing capacity of structure, because combined steel and concrete column is in the eccentric compression state mostly, therefore some reinforcing bar fails to surrender in the steel reinforced concrete of real abdomen formula, and the strength of materials is not in full use; Reinforcing bar in the open web type combined steel and concrete column by big angle steel, channel-section steel (can be welded) through level and the oblique batten plate integral body that is welded.When reinforcing bar is arranged at concrete outward flange or close outward flange, promptly become encased steel bone concrete column.At this moment, also reinforcing bar can be set in the post, also can reinforcing bar be set according to the design needs.China studies show that the open web type combined steel and concrete column, because reinforcing bar is to concrete effect of contraction, the bearing capacity of the reinforced concrete post of the identical steel ratio of open web type combined steel and concrete column bearing capacity ratio improves and surpasses 10%, and ductility has obtained obvious improvement.But because with respect to real abdomen formula steel reinforced concrete, its every slightly inferior properties, therefore " reinforced concrete composite structure tecnical regulations " (JGJ138-2001) stipulates this kind structure " should be used for non-seismic region or fortification intensity is the building of 6 degree ", and this has limited the application of open web type steel reinforced concrete structure undoubtedly.
The connected mode of present real abdomen formula combined steel and concrete column and reinforced concrete beam mainly contains all pass-through modes from the web of reinforcing bar edge of a wing side of vertical muscle, as shown in Figure 1, this kind form need be in web reserving hole, in engineering, this hole is often by water welding hole, and size is difficult for holding.If reinforcing bar is more, at the node area place, need cut off many holes, influence the intensity at this position.
In order to solve the deficiency of real abdomen formula and open web type combined steel and concrete column, I had once applied for utility model patent " the cellular combined steel and concrete column " (patent No.: 200520090801.8), proposed the notion of cellular combined steel and concrete column.It has solved the deficiency of the two cleverly, and the construction for bean column node simultaneously provides new thinking.But find that in application process it still has needs to replenish and improve part.
Summary of the invention
The object of the present invention is to provide a kind of cellular combined steel and concrete column and reinforced concrete beam frame node, the hole that it utilizes cellular combined steel directly passes reinforcing bar, props up template and concreting again.Solved the difficult problem of real abdomen formula combined steel and concrete column and reinforced concrete beam node construction.
