Abstract
Disclosed is a connecting device of a concrete filled steel tubular column and a reinforced concrete beam. The connecting device comprises steel corbels which are welded to the concrete filled steel tubular column, one ends of the steel corbels are provided with extension sleeves, and the reinforced concrete beam is fixed to the steel corbels through the extension sleeves. According to the connecting device of the concrete filled steel tubular column and the reinforced concrete beam, the extension sleeves are arranged on the connecting portions of the steel corbels and the reinforcing steel bars inside the reinforced concrete beam, and the concrete filled steel tubular column is provided with the structures of reinforcing outer ring plates and concentric inner ring plates, so that installation and fixed welding of the reinforcing steel bars in the concrete beam and the steel corbels can be achieved conveniently, safely and rapidly; the extension sleeves are welded to the steel corbels before construction, so that the quality safety of welding points can be effectively guaranteed and the field construction speed can be effectively increased; by means of the ring plates and the steel corbels, worry on cracks generated at the contact positions between the reinforced concrete beam and the wall of the concrete filled steel tubular column due to contact between concrete and the concrete filled steel tubular column can be avoided, and secondary treatment through other construction measures can be omitted, so that the construction cost can be saved.
Description
Technical field
The present invention relates to a kind of linkage for steel core concrete column and reinforced concrete beam, relate in particular to a kind of in engineering construction the linkage for steel core concrete column and reinforced concrete beam.
Background technology
The Shear force within the beam end transmission of cast-in-situ concrete beam column junction, steel corbel on available welding and steel pipe is realized, should not have component to pass steel pipe, in order to avoid affect building of pipe inner concrete, the reinforcing bar in concrete beam need adopt with reinforcing ring steel plate on steel corbel the method welding of downhand welding or overhead welding like this.Because it is sagging that the thawing metal under high temperature is easy to produce under Action of Gravity Field, under high temperature, the surface tension in molten bath is less, easily produces positive overlap, lack of fusion, slag inclusion, molten bath and watches the problems such as unclear, so overhead welding is a kind of welding method of very difficult grasp.If bar diameter is larger in the concrete beam being connected with steel column, upper and lower skin reinforcing bar row is many, and gap is little, the problem that exists like this welding difficulty greatly even cannot weld.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, and a kind of linkage for steel core concrete column and reinforced concrete beam providing, and it can solve the problem that concrete reinforcing steel and steel corbel are difficult to weld together.
The object of the present invention is achieved like this:
For a linkage for steel core concrete column and reinforced concrete beam, comprise steel corbel, steel corbel is welded on steel column, and the other end of steel corbel is provided with nigger, and concrete beam is fixed by nigger and steel corbel.
Described steel column is provided with reinforcement outer ring plate, strengthens outer ring plate and extends to above steel corbel.
Multiple niggers shape that linearly misplaces combines and forms nigger bond pads on steel corbel.
Described steel column is provided with interior concentric circles ring flat-plate.
Described concrete beam epithelium one placing of reinforcement is directly the two-sided welding in place at steel corbel.
Described nigger group and the two placing of reinforcement welding of concrete beam epithelium.
The present invention has obtained following technique effect:
First the present invention has adopted at steel corbel and concrete reinforcing steel junction and has been provided with nigger, and on steel column, be provided with the structure of strengthening outer ring plate and interior concentric circles ring flat-plate, can realize the installation of concrete reinforcing steel and steel corbel convenient, safely, quickly and be welded and fixed; Secondly nigger first welded with steel corbel before construction, can effectively ensure the quality safety of contact and improve on-the-spot speed of application; Due to the setting of ring flat-plate and bracket, concrete beam needn't worry that with steel pipe walls contact position concrete contacts the crack producing with steel column, does not need to do other construction measure and after-treatment again, has saved construction costs again; In addition it also has advantages of that molding effect is attractive in appearance, applied widely, node region is without other extra process.
Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the structure chart after the present invention is connected with steel column;
Fig. 2 is the structure chart after the present invention is connected with steel column and reinforcing bar.
Detailed description of the invention
For a linkage for steel core concrete column and reinforced concrete beam, comprise steel corbel 1 as shown in Figure 1-2, steel corbel 1 is welded on steel column 2, and the other end of steel corbel 1 is provided with nigger 3, and concrete beam 5 is fixing with steel corbel 1 by nigger 3.Steel column 2 is provided with strengthens outer ring plate 4, strengthens outer ring plate 4 and extends to above steel corbel 1.Multiple niggers 3 shape that linearly misplaces combines and forms nigger group 8 and be welded on steel corbel.Steel column 2 is provided with interior concentric circles ring flat-plate 6.Concrete beam 5 epithelium one placing of reinforcements 7 are directly the two-sided welding in place at steel corbel 1.Nigger group 8 is welded with concrete beam 5 epithelium two placing of reinforcements 9.
While adopting said structure, the connected node of steel corbel welding nigger, arranges at concrete beam reinforcing epithelium reinforcing bar place in steel column process and strengthens outer ring plate and extend to steel corbel, and concrete beam hypodermis reinforcing bar place arranges interior concentric circles ring flat-plate.
Treat steel column size by drawing, after factory's roll bending completes, according to the position of concrete beam, sectional dimension, floor absolute altitude, and according to the row of concrete beam reinforcing, at steel column correspondence position weldable steel bracket (bracket steel plate thickness is according to calculative determination), and the long straight screw sleeve that directly welding processing factory customizes on steel corbel, in the situation that concrete beam reinforcing radical is more, the shape that multiple niggers linearly can be misplaced combines and forms nigger group.
Steel column is transported to behind scene, according to steel corbel location and the compound location of on-the-spot axis, and adjusts the absolute altitude of steel column according to the position of strengthening outer ring plate, after adjusting, field by using fixing steel plate is temporary fixed, wait check and accept by after carry out the welding of steel column butt joint weld seam.
Concrete beam two placing of reinforcements (except concrete beam epithelium one placing of reinforcement) with lengthen straight screw sleeve is connected, concrete beam is transmission internal force reliably, the rigidity within the scope of beam length is constant, structure stress analysis with reality just as.In the situation that concrete beam reinforcing radical is more, for ensureing welding quality, concrete beam reinforcing and nigger group are welded and fixed mutually.Concrete beam epithelium one placing of reinforcement is directly in the two-sided welding in steel corbel place, and with steel corbel lap length > 5d, weld bead height is controlled at 10mm.
After structural beams reinforcement installation completes, adopt the lumps of wood that structural beams hypodermis reinforcing bar is paved, pave height according to in-situ determination, be convenient to stirrup installation, and according to drawing requirement location colligation, then disturbing concrete.
