Multi-radian special steel reticulated shell structure manufacture method

Abstract

The invention discloses a multi-radian special steel reticulated shell structure manufacture method. The multi-radian special steel reticulated shell structure manufacture method comprises the steps of first performing simmer bending on steel tubes to make into multi-radian bent tubes, next performing sample plate manufacture on the multi-radian bent tubes, then performing radian checking and fine adjustment on the multi-radian bent tubes, performing assembling on the multi-radian bent tubes when the radians of the multi-radian bent tubes are qualified, wherein the assembling method is that the a tiled horizontal type circulation reverse assembling method is adopted to perform grouping assembling and pre-assembling between groups on the multi-radian bent tubes through an assembling jig frame of a multi-radian special steel reticulated shell structure, removing the pre-assembling between the groups, performing vertical type installation on each group of the multi-radian bent tubes, performing connection on the groups, accomplishing the manufacture of the whole multi-radian special steel reticulated shell structure. The multi-radian special steel reticulated shell structure manufacture method can enable the manufacture of the multi-radian special steel reticulated shell structure to be rapid, accurate and safe.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for manufacturing a multi-curved space steel reticulated shell structure. Background technique [0002] The steel structure project of Sunshine Kaidi Biomass 10,000-ton Synthetic Oil Porch Project uses Q235B material, the main frame is Φ159*10 round tube, and the support rod is Φ159*6 round tube. shell type. The space bending arc of the steel pipe varies in various ways, and 500mm is one arc segment, which is difficult to manufacture. The foyer is in the shape of FLP and has a unique structure, which is called "the second in the world and the first in China". After the installation of the steel structure of the porch is completed, it is necessary to lay CNC milled tempered glass on its upper part. The existing multi-arc space steel reticulated shell structure manufacturing method adopts steel pipe bending, ground sample inspection, assembly, and welding. It adopts the over...

AI Technical Summary

Problems solved by technology

The existing multi-arc space steel reticulated shell structure manufacturing method adopts steel pipe bending, ground sample inspection, assembly, and welding. It adopts the overall vertical installation, which is not only difficult to manufacture, but also low in installation efficiency. Moreover, the accuracy of the overall forming is poor, which cannot meet the requirements of the project. The quality requirements of the steel structure cannot meet the requirement of no gaps in the CNC milled tempered glass on the steel structure
