Embodiment 1

[0028] like figure 1 , The variable cross-section steel assembly according stands long arcuate cantilever beam of the preferred embodiment of the present invention, comprises a plurality of steel building element integrally connected, each steel building element comprising: a central supporting steel columns 101, cantilevered variable section 102 and an upper box beam tube 103. The center support 101 vertically disposed steel columns, steel columns and the central support 101 is cylindrical structure. Cantilevered variable section box beam 102 provided with a plurality root, a plurality of variable section cantilevered beam 102 supporting steel columns box 101 radially spaced around the center, and a plurality of cantilevered inner end portion becomes box-beam cross-section 102 respectively and center support 101 is fixedly connected to the upper portion of steel columns. An outer end portion of each cantilever beam 102 variable section box are respectively fixedly connected to th...

Embodiment 2

[0030] In this embodiment, if Figure 2-3 , The number of variable section cantilever beam is provided with a box-seven, seven cantilevered variable section box beam center support 101 radially spaced around the steel columns, each variable section cantilevered by multi-section box beams Box assembled from variable cross section. Cantilevered from the inner end portion of variable cross-sectional box-beam 102 to the outer end portion of variable cross-section multi-section unit Box longitudinal sectional height gradually decreases as Image 6 As shown, thus contributing member to reduce the weight itself, to ensure the structural safety.

[0031] Specifically, such as image 3 , The seven variable section cantilevered box beams arranged sequentially in the counterclockwise direction is a first variable section cantilevered box beam 201, the second variable section cantilevered box beam 202, the sixth variable section cantilevered box beam 206, a fourth variable section box cantilever...

Embodiment 3

[0036] The present invention further provides a method of assembling the construction of one of the above steel stands long arcuate cantilever beam of variable cross-section, comprising the steps of: assembling a plurality of variable section cantilevered box beam, and the entire assembly is completed after the root of overhang pick box girder variable section lifting; determining a plurality of cantilevered connection position variable section steel column box beams in the central support, central support and mounting hanging steel columns, respectively; the plurality of variable section box cantilever beam welding steel column on the central support; and each cantilevered variable section box girder supporting the outer end portions fixedly connected to the top of the steel column tube and through the upper center, and the two adjacent cantilevered box beam of variable section an outer end portion fixedly connected through the upper tube.

[0037] Further, such as Figure 4-5 Sho...

Abstract

The invention discloses an assembled steel structure of an ultra-long cantilevered variable-section arc-shaped beam of a stand and a construction method thereof. The steel structure assembly unit includes: a central supporting steel column, which is vertically arranged, and the central supporting steel column is a cylindrical structure; multiple cantilevered variable-section box beams, and multiple cantilevered variable-section box beams surround the center The supporting steel columns are radially arranged at intervals, and the inner ends of multiple cantilevered variable-section box girders are respectively fixedly connected with the upper part of the central supporting steel column; The upper round pipes are respectively fixedly connected to the top of the central support steel column, and the outer ends of two adjacent cantilevered variable-section box beams are fixedly connected through the upper round pipes.

Description

Technical field [0001] Technical Field The present invention relates to building construction, particularly to a construction method stands long arcuate cantilever beam of variable section steel assembly. Background technique [0002] Currently, many outdoor venues stands using gradient cantilevered arcuate cross-sectional box-beam design, novel and beautiful shape structure thereof, but also through the transparent roof and around the stand system designed to meet the requirements of indoor and outdoor air convection. However, due to the arcuate cantilever beam structure graded multi-section box shaped steel into complex shapes, so as to bring a larger steel construction difficult to install. [0003] Patent discloses a CN02520017U stands Prestressed structure cantilevered off beam construction, which includes a left mounted on the lower floor, the right row of pillars in the top of the left row of props mounted left off beam, in said the top of the right row has a right strut m...
