Embodiment 1

[0052] Such as Figures 1a-1e as well as Figure 2-Figure 4 As shown, the multi-storey high-height large space cantilever truss structure embedded with small orthogonal trusses includes vertical support cantilever trusses, cantilevered roof orthogonal small trusses, cantilevered floor large-span steel beams, transition Area steel frame. The vertical support cantilever truss ( Figure 1b ) is located at the ends of both sides of the multi-storey high-rise space, and is composed of cantilevered trusses composed of two "X-shaped" cross-layer diagonal bracing extending to the transition area, which is a core structure for vertical support and lateral force resistance; the cantilevered Picking the roof orthogonal to small trusses ( Figure 1c ) is located on the top of the roof of the large space, perpendicular to the vertical support cantilever truss and arranged at a certain distance, and is composed of multiple large-span small trusses, which together form the central support ...

The large cantilevered space is a large-span architectural functional space with a cantilever not less than 10 meters and a span not less than 20 meters.

[0082]Compared with the deficiencies of the prior art, the present invention provides a multi-layer high-height large-space cantilever truss structure embedded with small orthogonal trusses based on the combination of vertically supported cantilever trusses and cantilevered roof orthogonal small trusses. The central support frame realizes the large-space building function through the large-span steel beams on the cantilevered floor, and realizes the transition from the vertically cantilevered l...

Abstract

The invention relates to a multi-layer full-height large-space cantilever truss structure with embedded orthogonal small trusses. The multi-layer full-height large-space cantilever truss structure comprises vertical supporting cantilever trusses, cantilever roof orthogonal small trusses, cantilever floor large-span steel beams and transition area steel frames; the vertical supporting cantilever trusses are located at the ends of the two sides of a multi-layer full-height large space and composed of two X-shaped cross-layer cantilever trusses extending to the transition area; and the cantileverroof orthogonal small trusses are located at the top of a large-space roof and are orthogonal to the vertical supporting cantilever trusses, each cantilever roof orthogonal small truss is composed ofa plurality of large-span small trusses, and the cantilever roof orthogonal small trusses and the vertical supporting cantilever trusses jointly form a center supporting framework. The multi-layer full-height large-space cantilever truss structure with the embedded orthogonal small trusses has the beneficial effects that the structure system is reasonable in structure, and complex steel structural system design and bearing of high-position large-cantilever-area multi-layer full-height large-space building function and modeling can be achieved.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a multi-layer over-height and large-space cantilever truss structure embedded with small orthogonal trusses. Background technique [0002] The truss structure system is a grid-shaped beam structure composed of chords, vertical bars and diagonal webs. It is mainly used as a structural support frame for large-span, large overhangs and other architectural functions and special shapes. Large and large overhangs, etc., are widely used in large and complex public buildings with large spans, large overhangs, building functions, and high-level conversion requirements. [0003] For buildings with large overhangs and long-span functions at the same time, the overall system stress mode combined with cantilever trusses and long-span trusses is a reasonable and effective solution. When the main span is dominated by overhangs and supplemented by overhangs, it can be...
