Embodiment 1

[0047] The main structure of this embodiment is located between the 1A# building and the 1B# building of the headquarters base in the South Sichuan Port Area of ​​the Sichuan Free Trade Zone, and is mainly composed of two parts: a flat surface grid and a suspended grid. The structure form is: orthogonal and orthogonal quadrangular pyramid planar grid, and the node type is solder ball. The support form is: multi-point support of the lower chord. The entire network frame is supported by 8 supports, and the support distance is 64.55m in the length direction and 6.6m in the width direction. The steel grid installation height is 42.4m.

[0048] The steel grid frame is a special shape, with a maximum length of 64.55m, a maximum width of 17.6m, and a maximum height of 13.65m. The actual coverage area is 890㎡. It is a long-span space structure with a total weight of about 75 tons. The support method is multi-point support on the lower chord, and the sagittal height of the upper grid...

Abstract

The invention discloses a large-span spherical net frame integral lifting method. The large-span spherical net frame integral lifting method lifts large-span spherical net frames by adopting a mode ofcombining integral lifting with segmented lifting; upper chords and lower chords of upper layers of the net frames are integrally lofted through a total station for integral assembly; a reserved value of a springing height is set in the assembly process; multiple lifting equipment is used for integrally lifting and mounting the upper layers of the net frames; upper part structures integrally lifted are used for forming an operation platform; and lower part structures are assembled, lifted and connected in a segmented mode to form a whole, so that the aerial bulking of components is reduced, the scaffold use level is reduced, the aerial workload is reduced, the construction is safe and reliable, the construction risk is reduced, the construction efficiency is improved, and the control of the quality of the net frames and the control of the production safety are facilitated.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an integral hoisting method of a large-span spherical grid frame. Background technique [0002] With the continuous and innovative rapid development of the construction industry, people's requirements for buildings are not limited to functionality, usability, and economy, but more pursuit of unique appearance requirements, reflecting the trend of the new era, and building characteristics. Among them, the large-span space spherical grid frame is favored by the modern construction industry for its light weight, high rigidity, large span, flexible layout, beautiful appearance, and generous features. [0003] At present, the installation method of the large-span space spherical grid is: first assemble and weld the small units, and then lift the small units to the preparation site for high-altitude assembly, and perform high-altitude assembly and welding from...
