Problems solved by technology

However, for the architectural design of the terminal building where the roof and the facade need to be coherent to form an overall curved appearance, the above structure cannot be handled well at the intersection of the roof and the facade
The upper chord of the traditional truss is a circular tube, which intersects with the roof steel beam or the secondary arch, and the connection node processing is more cumbersome

Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Such as figure 1 As shown, a hyperbolic arc-shaped long-span steel truss in this embodiment has several support rods arranged at the bottom of the truss, and the support rods are used to transmit force to the lower frame. The truss includes a Y-shaped column 1, a first truss, and a second truss in two floors. The vertical plane where the Y-column 1 is located in the two floors is used as a symmetrical plane. The first truss and the second truss are arranged symmetrically along the symmetrical plane. The same-side ends of the first truss and the second truss are correspondingly connected to the bifurcated ends of the Y-shaped column 1 of the landing section on the same side. Among them, the first and second trusses respectively include a single-curvature truss 4, a hyperbolic truss 3 and a transition section bending and torsion box 2, w...

Abstract

The invention relates to a hyperbolic arc long-span steel truss and a manufacturing method thereof, belonging to the technical field of building steel structures. The trusses include two floor Y-shaped columns, a first truss and a second truss, the vertical plane where the two floor Y-shaped columns are located serves as a plane of symmetry, and the first truss and the second truss are symmetrical along the plane of symmetry It is set that the same-side ends of the first truss and the second truss are respectively connected to the Y-shaped columns of the landing section on the same side. body, and the two ends of the single-curvature truss are sequentially connected to the hyperbolic truss and the bending-torsion box in the transition section. This application adopts the welding or bolt-welding jointing method to reduce the difficulty of installation; the idea of ​​sub-assembly welding and assembly can effectively control the welding deformation and improve the dimensional accuracy of the components. The simulation pre-assembly method is used after the joint inspection of physical pre-assembly and simulated pre-assembly, which effectively ensures the accuracy of manufacturing assembly and improves work efficiency.

Description

technical field [0001] The invention relates to a hyperbolic arc long-span steel truss and a manufacturing method thereof, belonging to the technical field of building steel structures. Background technique [0002] For large-span buildings, such as airport terminals, gymnasiums, and exhibition venues, the roof is often composed of multiple parallel trusses, purlins, or secondary arches, and the common roof trusses are inverted triangular tube trusses or vertical plane tube trusses, and Most of them are plane arches, and the whole truss is supported by multiple steel columns. However, for the architectural design of the terminal building where the roof and the facade need to be coherent to form an overall curved appearance, the above structure cannot be handled well at the intersection of the roof and the facade. The upper chord of the traditional truss is a circular tube, which intersects with the roof steel beam or the secondary arch, and the connection node processing is...
