Embodiment 1

[0026] Such as Figure 1 to Figure 2 As shown, the super-high-rise core tube and the outer frame beam post-cast joint, including the core tube shear wall 1 and the outer frame beam 2, and the intersecting node of the core shear wall 1 and the outer frame beam 2 is provided with a pre-embedded slab 3 With the embedded steel 4, the embedded plate 3 is connected with the corbel of the embedded steel 4, and the embedded steel 4 is provided with pegs 5. The core tube shear wall 1 and the external frame beam 2 pre-embed steel bars 6, and the external frame beam 2 longitudinally stressed steel bars 6 are pre-embedded steel bar connectors 7 at the anchor end of the core tube shear wall 1. The steel bar connector 7 and the longitudinal stressed steel bar 6 of the outer frame beam 2 are connected by equal-strength straight threads. The embedded steel 4 is a single H-shaped steel. The setting of single H-shaped steel in the outer frame beam 2 greatly improves the shear bearing capacity...

Abstract

The invention discloses a post-cast joint between a super high-rise core tube and an outer frame beam, comprising a core tube shear wall and an outer frame beam, and a pre-embedded plate and an Pre-embedded section steel, the pre-embedded plate is connected to the corbel of the pre-embedded section steel; the core tube shear wall and the internal reinforcement of the outer frame beam are pre-embedded, and the longitudinal stress reinforcement of the outer frame beam is connected to the core tube shear wall A steel bar connector is pre-embedded at the end of the anchoring end, and the steel bar connector is connected with the longitudinally stressed steel bar of the outer frame beam by straight threads of equal strength. The core tube structure of the invention has high bearing capacity, short construction period, convenient construction and high efficiency.

Description

technical field [0001] The invention relates to a post-cast joint, in particular to a post-cast joint between a super high-rise core tube and an outer frame beam, and belongs to the technical field of construction. Background technique [0002] In the construction of the frame structure outside the core tube, in order to ensure the effective connection of the nodes and the good mechanical performance of the node domain, the traditional construction method is integral pouring at the intersecting nodes of the core tube shear wall and the frame beam. However, this leads to a long construction period, and the core tube can only "wait" for the frame beams layer by layer, pouring together, the construction efficiency is low, and the construction economy is very poor. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a post-cast joint between a super high-rise core tube and an outer frame beam, whic...
