A connection node between an outrigger truss member and a core tube

Abstract

The invention discloses a boom truss component and core tube connection node in a framework core tube structure system, belonging to the field of civil and structural engineering. The connection node comprises a boom truss upper chord and a boom truss lower chord which are intersected with a core tube shear wall; the upper chord extension section of the boom truss upper chord in the range of the core tube shear wall and the lower chord extension section of the boom truss lower chord in the range of the core tube shear wall are wrapped in the inner and outer sides of the core tube shear wall; and the inner and outer steel plates of the upper chord extension section and the lower chord extension section are fixedly connected through a connection plate embedded in the shear wall. The invention mainly aims to provide a node construction form which has reasonable stress, is convenient to construct and is safe and reliable.

Description

technical field [0001] The invention relates to the field of civil structural engineering, in particular to a node form used when a steel structure outrigger truss member is connected to a core tube when an outrigger reinforcement layer is set in a frame-core tube structure system. Background technique [0002] With the increasing application of super high-rise buildings, the frame-core tube structure system with outrigger reinforcement is frequently used in the design of building structures. In the frame-core tube structure system, the core tube generally adopts a concrete structure; the form of the outrigger truss mainly adopts steel structural members; in order to ensure the effective transmission of the axial force of the outrigger in the core tube, the upper and lower chords of the steel structure outrigger need It extends into the core tube shear wall and extends to communicate with the upper and lower chords of the outrigger on the other side of the core tube. The upp...

Problems solved by technology

When the thickness of the shear wall of the core tube exceeds the limit compared with the section width after the outrigger is reduced, the buried upper and lower chords will occupy the positions of a large number of vertical reinforcements and stirrups in the corner restraint members of the core tube, thus Affect the force of the core tube, especially when the two-way outrigger truss intersects at one point, the adverse effect is more obvious, and the construction is very difficult
