Embodiment Construction
[0016] Such as Figure 1-2 A connection device for a steel pipe concrete column and a reinforced concrete beam is shown, including a steel corbel 1 welded on a steel column 2, the other end of the steel corbel 1 is provided with an extension sleeve 3, and the concrete beam 5 is fixed with the steel corbel 1 through the extension sleeve 3. A reinforced outer ring plate 4 is provided on the steel column 2, and the reinforced outer ring plate 4 extends to the top of the steel corbel 1. A plurality of extension sleeves 3 are combined in a straight line dislocation shape to form an extension sleeve group 8 which is welded on the steel corbel. The steel column 2 is provided with an inner concentric ring plate 6 . A row of steel bars 7 on the concrete beam 5 are directly welded on both sides of the steel corbel 1. The extension sleeve group 8 is welded with the second row of steel bars 9 on the concrete beam 5 epidermis.
[0017] When the above structure is adopted, the steel cor...

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 [0001] The invention relates to a connection device for a steel pipe concrete column and a reinforced concrete beam, in particular to a connection device for a steel pipe concrete column and a reinforced concrete beam in engineering construction. Background technique [0002] The beam end shear force transmission at the junction of cast-in-place concrete beams and columns can be realized by welding and steel corbels on steel pipes. It is not suitable for parts to pass through steel pipes, so as not to affect the pouring of concrete in the pipes. The reinforcement ring steel plate on the legs is welded by flat welding or overhead welding. Because the molten metal at high temperature is easy to sag under the action of gravity, and the surface tension of the molten pool at high temperature is small, it is easy to cause problems such as front welding bumps, poor fusion, slag inclusions, and unclear viewing of the molten pool. A welding method that is difficult t...
