Macau's first single large span reticulated shell steel structure engineering cap

Guangzhou Steel News: Macau's first single large span reticulated shell steel structure engineering cap

Recently, MGM Cotai hotel project engineering sky cap. It is reported that the project is two-way bias diagonal saddle hyperboloid form a monolayer structure large span reticulated shell, is the first in Hong Kong and Macao regions.

Reporters learned that the project by the China Building World Group general contractor, China State Construction Steel Co., Ltd. is responsible for construction and deepening of the design, manufacture and install. Engineering is about 1900 tons of steel, the maximum span of 140 meters, the projection area of ​​nearly 1.5 standard football field.

The project design dynamic lightweight construction steel structure is necessary to ensure that "no weight overruns," but also "the body strong enough." How to root after more than 5,000 bars and non-standard sizes like 1500 nodes personalized design and production of combines is a not a small problem, it is built in steel design staff, they repeatedly conducting research , from the cellular to be inspired, creative use of external double hollow hexagonal prism nodes form a useful structure to reduce the weight of a quarter, and is configured to connect stable. In the production chain, the project also "experience" to a lot of difficulty. Steel engineering project by each node 6 sizes totaling 48 parts board group fight together in diameter from 40 centimeters to 100 centimeters, the number of welds from 40-50, built in steel production staff He said welding this node is simply in embroidery, but by concentric positioning optimization, weld optimization and other measures, useful for the production of precision error strictly controlled within the requirements of British Standard Specification 3 mm. In the apparatus of the process, the use of point-in support system in a small space to ensure the load path clear, while using three-dimensional coordinates of the law means good control precision by 144 support points.
