Problems solved by technology
The traditional partially outsourced composite beam needs to be equipped with longitudinal bars and stirrups outside the section steel to form a reinforcement cage, which makes the construction complicated. Moreover, it is necessary to add welding studs at the connection between the prefabricated beam and the prefabricated slab. The welding construction is difficult, and the complexity is not conducive to prefabricated buildings. assembly
And for the overall strength and shear capacity of composite beams, welded studs are not enough

Embodiment Construction
[0012] Such as figure 1 As shown, an assembled connection node between a composite beam and a prefabricated slab includes a prefabricated composite beam 1 and a prefabricated slab 6. The prefabricated composite beam 1 includes profiled steel and concrete, and the profiled steel includes a beam web 4 and beam flanges on both sides of the beam web 2. The side of the prefabricated composite beam 1 with the beam flange is set close to the prefabricated slab 6. The prefabricated slab 6 is provided with a cast-in-place concrete groove, and the prefabricated slab 6 at the place of the cast-in-place concrete groove is provided with bolt through holes. The prefabricated composite The bolt through holes on the beam 1 correspond to the bolt through holes on the prefabricated slab 6 one by one; The concrete layer 5 and the tension bolts 3 are arranged parallel and symmetrically with respect to the beam web 4 .

The invention discloses an assembled connecting node between a composite beam and a prefabricated slab. The connecting node comprises a prefabricated composite beam, a prefabricated slab and a cast-in-place concrete layer; a groove is reserved in the prefabricated slab, a bolt through hole is formed in the groove, the prefabricated composite beam is also reserved with a through hole correspondingto the bolt through hole in the prefabricated slab; a split bolt penetrates through the through holes in the prefabricated composite beam and prefabricated slab and extends into the groove of the prefabricated slab, pre-stress is applied on both ends of the split bolt to tension the split bolt, concrete is poured in the groove of the prefabricated slab, so that the assembled connection between thecomposite beam and the prefabricated slab is achieved. Compared with the conventional assembled node, the shear capacity is improved, the structural composite effect is improved, and the node reliability is improved.
Description
technical field [0001] The invention relates to an assembled building, in particular to an assembled connection node of a composite beam and a prefabricated slab. Background technique [0002] Prefabricated buildings are currently hot, and the state strongly supports the development of prefabricated buildings. The traditional partially outsourced composite beam needs to be equipped with longitudinal bars and stirrups outside the section steel to form a reinforcement cage, which makes the construction complicated. Moreover, it is necessary to add welding studs at the connection between the prefabricated beam and the prefabricated slab. The welding construction is difficult, and the complexity is not conducive to prefabricated buildings. assembly. And for the overall strength and shear capacity of composite beams, welding studs is not enough. Contents of the invention [0003] Purpose of the invention: the present invention discloses an assembled connection node between co...
