REVERSE INSTALLATION CONSTRUCTION PROCESS OF BOLT-BALL NET RACK CYLINDRICAL SHELL STORAGE BIN

摘要

A reverse installation construction process of a bolt-ball net rack cylindrical shell storage bin is divided into installation of a starting unit and installation of overhanging small splicing units, and comprises the steps of: using a numerical wind tunnel technology and a finite element algorithm to obtain sizes of net rack node rod members and making a construction drawing; completing the primary connection of the small splicing units on the ground in advance; completing the installation of the starting unit, the starting unit being divided into sections A, B and C, which are assembled using a crane for integral installation; performing overhanging installation on the small splicing units from two sides of the starting unit to two ends of the cylindrical shell; and performing subsequent installation of a panel and internal devices after the installation of the net rack.
