China Construction Eighth Bureau "Aluminum roof structure construction technology" reached the international advanced level

Recently, the “Key Technology for the Construction of Large Span Aluminum Alloy Roof Structure Systems with Large Span” independently developed by the General Contractor Company of the China Construction Eighth Engineering Bureau Co., Ltd. (abbreviated as China Construction Eighth Bureau) has been certified by the Shanghai Municipal Housing and Construction Committee, and the results have generally reached the international level. The advanced level, in which 250 meters span multi-curvature curved surface aluminum alloy structure roof structure installation technology has reached the international advanced level.

The results were systematically studied for the features and difficulties of a 250 m multi-curvature curved surface aluminum alloy structural roof, a 140 m-span ellipsoidal aluminum alloy structure, and a 130 m-span hyperbolic hollow ceiling structure, and innovative use of curved surface sliding technology and matching The aluminum alloy sliding construction bearing, the steel structure assembling tire frame, and the high space frame-type tray buckle operation frame technology effectively solve the installation problem of a large-span multi-curvature curved surface aluminum alloy structure roof and forms a The construction method of the special-shaped curved aluminum alloy structural system provides experience for the construction of the large-span special-shaped curved surface structure engineering.
