Fabricated steel-concrete structure column-beam unbonded prestressed node structure and construction method
The invention discloses a fabricated steel-concrete structure column-beam unbonded prestressed node structure and a construction method. The construction process comprises the following steps of a, manufacturing a steel structure column; b, binding column steel bars and checking positions; c, aligning in place, and hoisting the steel structure column; d, carrying out reinforcement penetrating treatment on main reinforcements at the column-beam joints; e, installing vertical supports of the prefabricated superposed beams; f, hoisting the prefabricated superposed beam; g, connecting reinforcing steel bar grouting sleeves at post-pouring sections of the beam-column joints; h, erecting a template at a post-pouring section; i, carrying out tendon penetrating treatment and position arrangement and fixation at unbonded prestressed tendons at the joints of the column and the beam; j, connecting and grouting the steel bar sleeve in the post-cast section; k, carrying out concrete pouring on the steel-concrete structural column and the post-pouring section; l, tensioning and anchoring the unbonded prestressed tendons; m, dismantling the formwork and the supporting frame body; n, repeating the step b to the step m, and completing construction of all the steel-concrete structure column-beam unbonded prestressed joints on the same layer; o, repeating the step b to the step m until overall construction is completed; and p, carrying out overall acceptance. The steel-concrete structure column beam structure is reasonable in design, the technical scheme is feasible and effective, and the node anti-seismic property is good.
