Detailed description of the invention
This node is the connected node of reinforced concrete beam and concrete-filled steel square tubular column.Generally there are two kinds of connected node modes in reinforced concrete beam and concrete-filled steel square tubular column: one, hinged joint; Two, structures with semi-rigid joints.These two kinds of modes all can not ensure just to connect completely.This kind of node structure that existing the utility model provides, can as the form completely just connect of reinforced concrete beam and concrete-filled steel square tubular column, and namely shearing can be transmitted by shearing resistance bracket, and moment of flexure is divided into two parts transmission: one, bracket passes to post; Two, ring beam balance left and right sides moment of flexure;
Fig. 1 is that rectangular steel-tube concrete column coagulates Tu Liang with reinforcing bar and is connected detail drawing, is node area cross section.Coagulate native beam 2 connected node district at rectangular steel-tube concrete column 1 and reinforcing bar and reinforced concrete circle beam 3 is set, be provided with steel corbel with reinforced concrete beam link position.When the reinforcing bar of rectangular steel-tube concrete column both sides coagulate native depth of beam different time, it is identical that ring depth of beam and higher reinforcing bar coagulate native depth of beam.When the steel corbel height of rectangular steel-tube concrete column both sides is different, in rectangular steel-tube concrete column, sash plate 11 is separately positioned on corresponding absolute altitude place, the steel corbel edge of a wing.In figure, B is deck-siding, and b, h are post length and width.
The way of composition graphs 2 node area ring beam, H is ring beam vertical height.Establish shear stud 31 to be connected with rectangular steel-tube concrete column 1 in ring beam 3, prevent from occurring slide surface between ring beam 3 and rectangular steel-tube concrete column 1.Arrange main muscle 32 and waist muscle 33 in ring beam, bore a hole when main muscle 32 meets steel plate and pass through, main muscle 32, waist muscle 33 are bound round by stirrup 34 and prick permanent position.
Composition graphs 3 node area steel corbel 4 structure is set, H is ring beam vertical height.Steel corbel adopts H profile steel.The height of bracket and reinforcing bar coagulate native beam section relation, and H profile steel two edge of a wing identity distances are identical from the distance of two end faces of reinforced concrete beam, are 100-150mm in the present embodiment.
The connected mode of muscle and steel corbel indulged by composition graphs 4, Fig. 5 reinforced concrete beam, take the vertical junction plate on the bracket in section shown in vertical junction plate 41(Fig. 4 of the mode of Site Welding and steel corbel) be connected, ensure that vertical muscle internal force effectively can pass to rectangular steel-tube concrete column, both moment of flexure can effectively be transmitted.H profile steel in the present embodiment.As Fig. 4, reinforced concrete beam is indulged in muscle, during single vertical muscle≤6 piece, wherein be positioned at 4 vertical muscle 21 of both sides through rectangular steel-tube concrete column, maximum 8 of all the other vertical muscle 22() with the vertical junction plate on the bracket in section shown in vertical junction plate 41(Fig. 4 of steel corbel) weld, vertical muscle 21 carries out hoop with waist muscle 22 by stirrup 23 and pricks permanent position.As Fig. 5, reinforced concrete beam is indulged in muscle, when 6≤outer row indulges muscle≤8 piece, is wherein positioned at 4 vertical muscle 21 of both sides through rectangular steel-tube concrete column, all the other (maximum 12) weld with the vertical junction plate 41 of steel corbel, and vertical muscle and waist muscle 22 carry out hoop by stirrup 23 and prick.
