Description
Technical Field
The utility model relates to a structural architecture technical field, concretely relates to assembled platform canopy beam column nodal connection structure.
Background
The prefabricated concrete structure is one of the most applied and researched industrialized structural systems at home and abroad at present, and the core part of the prefabricated concrete structure is a beam-column connecting node. The construction mode of the connecting node and the anti-seismic performance of the connecting node not only influence the construction efficiency of the assembled structure, but also directly determine the overall anti-seismic performance of the structure.
Most of current assembled beam column node, the wholeness can be relatively poor, pours concrete node after through and to beam column interconnect, and this kind of connection can not reach cast-in-place beam column's wholeness level and ductility is not enough, and the node destroys easily under the reciprocal effect of earthquake, leads to the structure inefficacy.
SUMMERY OF THE UTILITY MODEL
The utility model provides an assembled platform canopy beam column nodal connection structure, it is through applying prestressing force to the prestressing steel who passes precast beam, makes precast column and the inseparabler connection of precast beam, waters the concrete through the back and forms a whole to the beam column.
For solving prior art problem, the technical scheme of the utility model is that an assembled platform canopy beam column nodal connection structure, including precast beam and precast column, precast beam set up in precast column top portion, precast beam's upper portion be provided with canopy board, precast column's top be provided with the rectangular channel that is used for placing precast beam, its characterized in that: the rectangular channel is vertically provided with prestressed reinforcement, the middle part of precast beam run through and be provided with reserved reinforcing bar hole, the number of prestressed reinforcement and reserved reinforcing bar hole is corresponding.
Further, the prestressed reinforcement is fixed by a prestressed reinforcement anchor.
Furthermore, the number of the reserved steel bar holes and the number of the prestressed steel bars are respectively 4.
Furthermore, two ends of the precast beam are respectively provided with a precast edge sealing beam.
Furthermore, the upper part of the prefabricated column is provided with a prefabricated longitudinal flat beam.
Furthermore, post-cast concrete column caps are cast on the prestressed reinforcements on the upper parts of the prefabricated columns.
Compared with the prior art, the utility model has the advantages as follows:
1. the utility model discloses the beam column node passes through prestressed reinforcement and is connected with the precast beam, connects inseparabler, and pressure between the contact surface increases, and the shearing resistance between the beam column strengthens under the horizontal seismic action, and the beam column can not take place the level and slide relatively.
2. The ascending reciprocating motion of one side below can appear in precast beam under the earthquake effect, and relative motion between precast beam and the precast column easily causes the destruction of post-cast concrete between the beam column, the utility model discloses the beam column passes through prestressed reinforcement and connects, has retrained the relative motion of precast beam and precast column at the node, is a protection to post-cast concrete.
