A Steel Support Tube-Drop-Hanging Truss System and Its Application

Abstract

The invention discloses a steel support tube-bottom-hanging truss system with large arc-shaped openings on the facade and its application. The combination of the steel support cylinder is a central support-steel frame form, including double support cylinders at the left end and right end; the multi-layer hanging truss is located at the top of the middle large span, and is composed of 4 large-span multi-layer one-way trusses; The floor structure includes the upper whole floor and the lower part of the floor, and the column-free supporting floor is connected by suspended steel columns; the single-layer curved reticulated shell is suspended under the main structure to realize the shape of a curved surface with large openings. The present invention is based on the overall force-bearing mode of the combination of the steel support cylinder and the multi-layer hanging truss, the suspension steel column is connected to the column-free support floor, and the single-layer curved reticulated shell is suspended to realize the arc-shaped large opening shape of the facade, and the component composition The module is clear, the structure is reasonable, the force transmission is clear, it has the advantages of large span, high bearing capacity, high overall rigidity and large opening on the curved surface, and has a wide range of applications.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a steel support cylinder-under-hanging truss system with a large arc-shaped opening on the facade. Large openings refer to openings in the facade of large-space buildings with a span of not less than 60 meters. Background technique [0002] The frame-truss structure system is a rigid truss form composed of chords, vertical rods and diagonal braces as a large-span structural support, combined with an overall structural system composed of a frame floor structure. The truss support structure has the advantages of light weight, high stiffness and The overall structural system is widely used in large-scale complex high-rise public buildings with large-span and high-level conversion. [0003] According to the relative position of the vertical space between the truss and the frame, it can generally be divided into top-supporting truss, bottom-hanging truss an...

Problems solved by technology

[0007] In addition, the steel support tube-bottom-hanging truss system has problems such as complex node connection structure, complex component assembly, complex mechanical performance of the system, and large-span seismic and comfort handling. The form design and assembly scheme of the tube-bottom-hanging truss system are also an important factor to ensure its load-bearing performance and normal use
