Embodiment 1
[0018] In the first step, the frame column 1 is formed by pouring at the construction site, and the corbel 2 protrudes from the joint of the frame column 1 and the main beam 5 on the column, and the corbel 2 and the beam head of the main beam 5 are connected. Three connecting high-strength bolt embedded parts 3 in the shape of a product are embedded on the supporting surface; three connecting holes 4 are set on the beam head of the main beam 5, and the three connecting holes 4 are matched with the three high-strength bolt embedded parts 3 , Two hoisting hooks are reserved for the prefabricated beam. When the prefabricated beam is hoisted, the high-strength bolt embedded part 3 penetrates into the reserved hole 4, and the gap in the hole is filled with high-strength grouting material to ensure that it meets the seismic requirements.
[0019] The second step is to solve the connection between the main beam 5 and the secondary beam 6. When the main beam 5 is prefabricated, at the ...

The invention discloses a construction method of a cast-in-place column prefabricated beam-slab structure, which comprises frame columns, beams, corbels, plates and high-strength bolt embedded parts; the frame columns are formed by on-site casting during construction, and the beams and plates Prefabricated beams and prefabricated slabs are prefabricated, and the prefabricated beams include prefabricated main beams and secondary beams; the joints between the frame columns and the main beams protrude from the columns, and the corbels are connected to the beam heads of the main beams, and the main beams Set up a few-shaped joints, set the lap joints at the beam head of the secondary beam, and make the connection between the side of the main beam and the prefabricated slab into a "convex" shape, so that the prefabricated slab is supported on the side of the main beam. The construction method of the present invention solves the problem of quick connection of structural joints between columns and main beams, main beams and secondary beams, and beams and slabs, achieves fast and efficient construction, shortens the construction period, saves construction costs, and at the same time meets the requirements for improving earthquake resistance and avoids the need for connection Complicated, complex and hidden dangers of quality defects at the joints.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method of a cast-in-place column prefabricated beam-slab structure. Background technique [0002] The existing construction methods of high-rise building frame structures are all cast-in-place columns, beams, and slabs and prefabricated columns, beams, and slabs; the all-cast-in-place construction system has a long construction period, and the formwork support system uses many materials and consumables, and the cost is high; and For the fully prefabricated construction system, the anti-seismic construction requirements at the beam-column joints are relatively high and cumbersome, which is likely to cause hidden dangers of construction quality defects. The use of cast-in-place column prefabricated beam-slab structure construction system can effectively overcome the cumbersome and complicated construction difficulties of the fully prefabricated frame...
