Abstract
The invention discloses a connecting structure for a steel structure column and a reinforced concrete beam. The connecting structure comprises a steel structure column, a reinforced concrete beam and a steel rib. The steel rib is embedded in the reinforced concrete beam in such a pattern that the length direction of the steel rib is consistent with that of the reinforced concrete beam. The steel structure column is radially inserted in the reinforced concrete beam to be fixed on the steel rib. The steel structure column is welded on the steel rib. The steel structure column is provided with a column footing stiffening rib. The steel rib is provided with a support stiffening rib. The length of the steel rib is longer than the setting of the cross section width of the steel structure column according to a preset proportion. The steel rib is arranged in the reinforced concrete beam and the reinforced concrete beam and the steel rib are rigidly connected in a way of fixing the steel rib and the steel structure column, so that the connecting structure is stable without exposing any part. The height of the steel rib matches with the height of the reinforced concrete beam, so that the connecting form of the invention can be suitable for reinforced concrete beams with various heights.
Description
Technical field
The present invention relates to the syndeton of a kind of steel structure column and reinforced concrete beam.
Background technology
In prior art, the structure mainly used for steel structure column and the syndeton of reinforced concrete beam has: articulated manner is connected; The mode that just connect connects, and the mode that wherein just connect connects and be divided into plug-in type and exposed two kinds of structures.
The defect that articulated manner connects mainly is, this connected mode makes can relatively rotate between steel structure column and reinforced concrete beam, therefore cannot transmit moment of flexure preferably, needing the connecting portion carrying out moment of flexure transmission, may cause the instability of structural entity.Articulated structure needs to adopt bearing pin node or other exposed types of attachment on the other hand, can affect attractive in appearance.
The exposed mode that just connect connects and also can be exposed to outer because connecting and affect attractive in appearance.
At present, also have and use inserted type rigid connection to carry out the technology connected, but this technology will be used for steel structure column and the firm of reinforced concrete beam connects in succession, requirement is had to the height of reinforced concrete beam, because when the height of reinforced concrete beam is too small, steel structure column can be caused to insert reinforced concrete beam excessively shallow, so cause connecting between the two unreliable.
Summary of the invention
The technical problem to be solved in the present invention connects unstable, exposed connection impact defect attractive in appearance to overcome prior art, and provide a kind of Stability Analysis of Structures, syndeton is not exposed to outer steel structure column and the syndeton of reinforced concrete beam.
The present invention solves above-mentioned technical problem by following technical proposals:
A syndeton for steel structure column and reinforced concrete beam, its feature is, it includes: a steel structure column, a reinforced concrete beam and a reinforcing bar; Described reinforcing bar is embedded in described reinforced concrete beam according to the form that length direction is consistent with the length direction of described reinforced concrete beam; The described reinforced concrete beam of insertion of described steel structure column radial direction and described reinforcing bar fix.That is, reinforcing bar and steel structure column all insert reinforced concrete beam and fix, more stable relative to not arranging steel skeleton structure like this, so go for the reinforced concrete beam connecting various height, and be unlikely to because steel structure column inserted and shallowly causes instability.
Preferably, described steel structure column welds with described reinforcing bar.
Preferably, described steel structure column is provided with suspension column stiffening rib, described reinforcing bar is provided with bearing stiffening rib.Suspension column stiffening rib and bearing stiffening rib are conventional stiffening rib fixed structure herein.
Preferably, the breadth of section that the length of described reinforcing bar is greater than described steel structure column according to a preset ratio is arranged.That is, reinforcing bar length is greater than the breadth of section (i.e. the height of reinforced concrete beam) of steel structure column, can set arbitrarily as required.
Preferably, described reinforcing bar is provided with a plurality of shear stud along its length.Acting as of shear stud prevents reinforcing bar along its length because of shearing force and reinforced concrete beam relative sliding herein, can effectively by shear transfer to reinforced concrete beam.
Preferably, described reinforced concrete beam inside is provided with complex root reinforcing bar, and described reinforcing bar is fixed by sleeve and described reinforcing bar.Sleeve is the structure being usually used in fixing reinforcing bar and steel material in steel concrete in prior art in plug-in type connects herein.
Preferably, the part of the described reinforced concrete beam of insertion of described steel structure column is also provided with and a plurality ofly wears muscle hole for what wear described reinforcing bar, described reinforcing bar is by wearing muscle hole described in being arranged in and described reinforced concrete beam fixes.
Positive progressive effect of the present invention is: by reinforcing bar built-in in reinforced concrete beam, and mode reinforcing bar and steel structure column fixed just has connect reinforced concrete beam and steel structure column, makes the syndeton of the two stable and without exposing; The height of reinforcing bar can be set, make syndeton of the present invention go for the reinforced concrete beam of various height.

Fig. 1 is the side sectional view of the syndeton of steel structure column and reinforced concrete beam in the present embodiment, Fig. 2 is the section plan of the syndeton of steel structure column and reinforced concrete beam in the present embodiment, as shown in Fig. 1 ~ 2, the syndeton of the steel structure column that the present embodiment relates to and reinforced concrete beam includes: steel structure column 1, reinforced concrete beam 2 and reinforcing bar 3;
Wherein, reinforcing bar 3 is embedded in reinforced concrete beam 2 according to the form that length direction is consistent with the length direction of reinforced concrete beam 2; The insertion reinforced concrete beam 2 of steel structure column 1 radial direction welds mutually with reinforcing bar 3.
In addition, steel structure column 1 is provided with suspension column stiffening rib 6, reinforcing bar 3 is provided with bearing stiffening rib 5.
In addition, the length of reinforcing bar 3 is greater than the setting of the breadth of section of steel structure column 1 according to a preset ratio, is set greater than steel structure column 1 breadth of section 4 times herein.
In addition, reinforcing bar 3 is provided with along its length a plurality of shear stud 7.
In addition, reinforced concrete beam 2 inside is provided with complex root reinforcing bar, and reinforcing bar is fixed by sleeve (not marking in figure) and reinforcing bar 3.
The part of the insertion reinforced concrete beam 2 of steel structure column 1 is also provided with and a plurality ofly wears muscle hole 4 for what wear reinforcing bar, reinforcing bar fixes with reinforced concrete beam 2 by being arranged in muscle hole 4.
