Embodiment 1
[0034] The specific embodiment of the present invention will be described in detail in conjunction with the accompanying drawings.
[0035] The first stage:
[0036] For a super high-rise reinforced concrete frame-core tube structure, according to the structural design requirements, the prefabricated beam intersects with the shear wall outside the plane, the cross section of the beam is 400mm×900mm, and the beam span is 10m. For HRB400, determine that the extension length of the connecting section 3 is 1000mm, the width is 400mm, the length of the post-casting section is 1000mm, and the part in contact with the post-casting node is set with a horse-toothed bar, and the connecting steel bars are arranged in the 3rd, and the labels and diameters of the steel bars They all correspond to the ordinary stressed steel bars in the prefabricated beam one by one, the upper and lower longitudinal bars and torsion-resistant waist bars all protrude 500mm from the beam plane, and the proces...
