Embodiment 1

[0048] Such as figure 1 a-1e and Figure 2-Figure 4 As shown, the vertical long cantilever truss structure used for the support of the spiral ascending curtain wall includes a vertical long cantilever truss, a ring connecting steel beam, a lateral support structure, and a bottom rigid support. The vertical long cantilever truss ( figure 1 b) Consists of a series of single vertical long cantilevered trusses arranged in a multi-circle spiral, adopting the grid structure of planar tube trusses, and the top elevation of the vertical long cantilevered trusses are arranged according to spiral ascending gradients, forming a vertical anti-lateral force support core structure; the hoop connecting steel beams ( figure 1 c) It consists of two hoop-connected steel beams located at the top of all vertical long cantilever trusses and the middle of the superelevation vertical long cantilever trusses in the inner circle. The steel beam connection setting at the middle elevation position be...

Embodiment 2

[0063] Such as Figure 9 As shown, the specific component assembly process of the vertical long cantilever truss structure used for spiral ascending curtain wall support is as follows:

[0064] (1) The vertical main chord 1 of the vertical long cantilever truss, the first inclined main chord of the lower section, the second main chord of the upper section 3, the horizontal branch of the vertical long cantilever truss 4, the vertical long overhang The oblique branch tubes 5 of the cantilever truss form the basic unit of a single vertical long cantilever truss in the form of a "single oblique bar" planar tube truss; knuckle point 6;

[0065] (2) The single vertical long cantilever truss is arranged along the normal direction of the vertical curtain wall surface, with the central positioning point 15 as the center of the spiral, and multiple vertical long cantilever trusses are arranged to form a vertical long cantilever with multi-turn spiral arrangement In the truss structure...

Embodiment 3

[0072] This patent also provides an application of a vertical long cantilever truss structure supported by a spiral ascending curtain wall in the design and bearing of a steel structure frame system supported by a vertical superhigh cantilever curtain wall supported by multi-circle spiral ascending arrangements on the roof. The above-mentioned vertical long cantilever refers to a vertical long cantilever truss with a vertical single cantilever height not less than 10 meters.

[0073] Compared with the deficiencies of the prior art, the vertical long cantilever truss structure provided by the present invention for spiral ascending curtain wall support is based on the central support frame combining the vertical long cantilever The support structure provides middle support for the super-high truss, and forms a single-cantilever vertical truss form through rigid supports, which can realize the shape and function of vertical super-high cantilevered curtain walls and curved building...

Abstract

The invention relates to a vertical long cantilever truss structure used for spiral ascending curtain wall support, comprising a vertical long cantilever truss, a ring connecting steel beam, a lateral support structure and a bottom rigid support; the vertical long cantilever The trusses include several single vertical long cantilever trusses arranged in multi-circle spirals, adopting the structure form of planar tube trusses, and the top elevation positions of the vertical long cantilever trusses are arranged according to the spiral ascending gradient, forming the vertical lateral force resistant supporting core structure; The hoop connecting steel beams are mainly composed of two hoop connecting steel beams located at the top of all vertical long overhanging trusses and in the middle of the super-high vertical long overhanging trusses in the inner ring, The hoop-connected steel beams are spirally connected with the top of the truss. The beneficial effects of the present invention are: based on the analysis of the ultimate load-bearing performance, the structure of the present invention is convenient to be controlled by indicators such as overall stiffness and bearing capacity, so as to further ensure the rationality and effectiveness of the overall structural system.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a vertical long cantilever truss structure used for spiral ascending curtain wall support. Background technique [0002] The truss structure system is a lattice beam structure composed of chords, vertical rods (or horizontal rods) and diagonal bracing members, including horizontal truss structures and vertical truss structures. The horizontal truss structure is mainly used for large-span buildings and roof structures in large public buildings such as exhibition halls and gymnasiums; the vertical truss structure is used as a structural lateral support frame for special architectural shapes such as multi-storey full-height curtain walls and facades. widely used in. [0003] Vertical truss systems can generally be divided into vertical truss systems that are simply supported at both ends and cantilevered in one direction according to the restraint forms o...
