Background technology

The structural system of highrise building adopts the Core Walls Structure steel-concrete combined structure more, and when wherein girder steel was connected with concrete, traditional node way comprised:

1, default embedded part in concrete.In traditional embedded part way, the straight anchor length requirement of dowel is longer, easily and reinforced concrete column, steel frame beam in concrete interfere, be difficult to reach designing requirement;

2, in concrete, reinforcing bar cornice bracket is connected with girder steel.In Modern Construction Technology, core wall structure adopts sliding mode technology to build more, need to keep outer facade smooth, however the outstanding concrete of bracket facade outward in this kind design of node, can't slding form operation in construction, affect the duration, and can't pass through bracket at reinforcement in concrete.

The utility model content

For the problems referred to above, the purpose of this utility model is to provide a kind of reinforced concrete column and steel beam connecting joint.

For achieving the above object, a kind of reinforced concrete column described in the utility model and steel beam connecting joint, at least comprise reinforced concrete column, girder steel and the end plate and the bracket that connect reinforced concrete column and girder steel, wherein, described bracket by at grade evenly a plurality of steel plates of spaced apart consist of, one end of each steel plate and reinforced concrete column welding, the other end and end plate welding; The outer face of described end plate is provided with junction plate, and described junction plate connects described girder steel.

Preferably, described bracket by at grade evenly a plurality of stave sheets of spaced apart consist of, and stave sheet is vertical with end plate.

Preferably, described bracket is by even a plurality of stave sheets of spaced apart at grade, and is positioned at the horizontal steel plate that welds on the stave sheet at two ends and consists of, and stave sheet is all vertical with end plate with horizontal steel plate.

The beneficial effects of the utility model are:

The utility model is in conjunction with the advantage of common dowel embedded part and steel corbel way, and making reinforced concrete column, bracket and end plate is an integral body, reliable in structure, be convenient to civil engineering and transportation, make the concrete column reinforcing bar in order by reinforced concrete column, have convenient, the economic security of construction, the advantage that industrialized level is high.

The specific embodiment

Below in conjunction with Figure of description, the utility model is further described.

The described a kind of reinforced concrete column of the utility model embodiment and steel beam connecting joint, at least comprise reinforced concrete column 2, girder steel 5 and the end plate 3 and the bracket 4 that connect reinforced concrete column and girder steel, wherein, described bracket by at grade evenly a plurality of steel plates of spaced apart consist of, one end of each steel plate and reinforced concrete column welding, the other end and end plate welding; The outer face of described end plate is provided with connector, and described junction plate 6 connects described girder steel.

Explanation makes an explanation as an example of H shape reinforced concrete column example:

Embodiment 1, be illustrated in figure 1 as with the H shape reinforced concrete column of floor 1 wherein the external surface of a frange plate top view of bracket is set.In the drawings, can see, H shape reinforced concrete column is placed in concrete wall, and bracket is welded on the external surface of described frange plate, the welding of the other end of end plate and bracket, and Transducers Embedded in Concrete is within the walls, and concordant with metope.Junction plate on end plate connects girder steel.Be illustrated in figure 2 as the view on the A-A direction in Fig. 1.In Fig. 2, described bracket is by even a plurality of stave sheets 9 of spaced apart at grade, and is positioned at the horizontal steel plate 8 that welds on the steel plate riser at two ends and consists of, and stave sheet is all vertical with end plate with horizontal steel plate.A plurality of stave sheets form riser gap avoids reinforcing bar and girder steel, reinforced concrete column to interfere in order to facilitate passing of reinforcing bar.Be illustrated in figure 3 as the view on the B-B direction in Fig. 2, can find out in Fig. 3, bracket is with the structure distribution situation of stave sheet and horizontal steel plate.

The three-dimensional connection layout of above-mentioned reinforced concrete column and bracket, end plate, junction plate and girder steel is seen as shown in Figure 7.

Embodiment 2, are illustrated in figure 4 as the top view that bracket is set with corresponding two frange plates 10 of H shape reinforced concrete column of floor.In the drawings, can see, H shape reinforced concrete column is placed in concrete wall, and bracket is welded on respectively on the side of described two frange plates, the welding of the other end of end plate and bracket, and Transducers Embedded in Concrete is within the walls, and concordant with metope.Junction plate on end plate connects girder steel.Be illustrated in figure 5 as the view on the C-C direction in Fig. 4.In Fig. 2, described bracket by at grade evenly a plurality of stave sheets of spaced apart consist of, and stave sheet is vertical with end plate.A plurality of stave sheets 9 form riser gap 7 avoids reinforcing bar and girder steel, reinforced concrete column to interfere in order to facilitate passing of reinforcing bar.Be illustrated in figure 6 as the view on the D-D direction in Fig. 5, can find out in Fig. 6, bracket is with the structure distribution situation of steel plate riser.If stave sheet interval, both sides is excessive, a row dowel is set, dowel 11 and end plate 3 perforation plug weldings in the middle of end plate.

Reinforced concrete column also can adopt king's font reinforced concrete column, cross reinforced concrete column, as Fig. 8 and the connected mode structure side view that is respectively king's font reinforced concrete column, cross reinforced concrete column and outside girder steel shown in Figure 9.
