Wherein, described concrete column (1), node connector (3), connector (4), composite beam I (21) and composite beam II (22) are condensed into entirety by concrete grout.
Further, described node connector (3) is steel reinforcement cage.
Further, described connector (4) is the negative reinforcement being arranged side by side.
Further, negative muscle I that described composite beam I (21) includes rectangular shape array and the framework that the stirrup I being equally spaced along negative muscle I bearing of trend is constituted, concrete pulp layer it is filled with in framework, negative muscle II that described composite beam II (22) includes rectangular shape array and the framework that the stirrup II being equally spaced along negative muscle II bearing of trend is constituted, concrete pulp layer it is filled with in framework, the stirrup I that described connector I (K) is exposed for composite beam I (21) top side, the stirrup II that described connector II (L) is exposed for composite beam II (22) top side, the negative muscle I (211) of described composite beam I (21) bottom, the negative muscle II (221) of composite beam II (22) bottom be respectively formed with extend to its body exterior can bending part (23).
This practicality provides the benefit that:
(1) in attachment structure, end face in concrete column is reserved with inserting groove, steel reinforcement cage it is provided with in inserting groove, it is linked as entirety by negative reinforcement side by side between steel reinforcement cage and composite beam, simultaneously the negative muscle bottom composite beam be provided with can bending part, after hoisted in position, bending part bending will can play the effect of riveted joint, after casting complete, the rigidity of attachment structure is significantly improved, and node connecting structure realizes being rigidly connected completely；
(2) be ensure that component quality greatly by precast beam, without inside and outside substantial amounts of scaffolding work, the cost making respective storey structure reduces by more than 10%, compared with traditional attachment structure, duration can shorten half, construction quality is improved simultaneously, and safety is substantially improved, and comprehensive benefit is extremely notable.

Detailed description of the invention
In order to make the technological means of this practicality, creation characteristic, reach purpose and effect is easy to understand, below in conjunction with being specifically illustrating, this practicality is expanded on further.
Referring to Fig. 1-4, a kind of attachment structure of concrete prefabricated beam and cast-in-place post, it includes the concrete column 1 cast in advance, end face in concrete column 1 is reserved with inserting groove 11, node connector 3 it is provided with in inserting groove 11, node connector 3 has the free end extended to outside inserting groove 11, end face in concrete column 1 is additionally provided with the composite beam 2 being connected as a single entity with node connector 3, wherein, composite beam 2 includes composite beam I 21, composite beam II 22, composite beam I 21, composite beam II 22 is laid in node connector 3 lateral symmetry, end face in composite beam I 21 is provided with connector I K, end face in composite beam II 22 is provided with connector II L, connector I K, connector II L is fixed as one by connector 4 and node connector 3.In molding, described concrete column 1, node connector 3, connector 4, composite beam I 21 and composite beam II 22 are condensed into entirety by concrete grout.
As preferably, the node connector 3 in the present embodiment is steel reinforcement cage.
As preferably, the connector 4 in the present embodiment is the negative reinforcement being arranged side by side, and after negative reinforcement is connected with steel reinforcement cage, its two ends are fixed with connector I and connector II respectively.
Composite beam I 21 are described further below, the structure of composite beam II 22, referring to Fig. 2, negative muscle I that composite beam I 21 includes rectangular shape array and the framework that the stirrup I being equally spaced along negative muscle I bearing of trend is constituted, concrete pulp layer it is filled with in framework, negative muscle II that composite beam II includes rectangular shape array and the framework that the stirrup II being equally spaced along negative muscle II bearing of trend is constituted, concrete pulp layer it is filled with in framework, connector I K is the stirrup I that composite beam I 21 top side is exposed, connector II L is the stirrup II that composite beam II 22 top side is exposed, simultaneously, negative muscle I 21 bottom composite beam I 21, negative muscle II 221 bottom composite beam II 22 be respectively formed with extend to its body exterior can bending part 23, treat composite beam I 21, after composite beam II 22 installation in position, by can bending part 23 to the effect playing riveted joint after inserting groove 11 bending.
