GRC Board Installation Report of Nanjing Youth Olympic Conference Center

On August 16, 2014, the second World Youth Olympic Games will be held in Nanjing, Jiangsu. As a supporting service facility for the Youth Olympic Games, the Nanjing Youth Olympic Conference Center (referred to as the “Green Olympic Center”) has become an international stage for Chinese enterprises to display a good image.

The curtain wall of the Nanjing Youth Olympic Conference Center has selected GRC panel decoration materials for a total of 85,000 square meters and 12,500 pieces. It is currently the largest single GRC panel installation in China. In the meantime, more than 25,000 crossing bovine legs pass through the waterproof layer, and a total of 3,400 windows are planned on the facade. These are special features of this project.

The Nanjing Youth Olympic Conference Center has no construction drawings for the secondary steel structure installation. The Planning Institute only provides models and calculation results. This is the first major problem faced by the project. The project touches on many specialties, and steel structures, prestressing, GRC panel roofing, and curtain wall waterproofing are all required to be further planned. The three planners spent nearly one year and completed more than 20,000 plans for deepening plans, more than 10,000 drawings, and more than 10,000 drawings.

The project is common in design, with many specifications, large quantities, and high difficulty of installation. The project plate has 80,000 square meters, a total of 12,500 pieces, divided into shaped plates and standard version, the largest plate has 26 square meters, the smallest as long as 1 square meter. In particular, it is even more difficult for the device with an inclined surface and an inclined surface.

Its installation is difficult. The engineering board has two kinds of special-shaped board and specification board. There are many kinds of specification board among them: there are windows with windows and windows without windows; there are large ones and small ones. Its device is not on a plane, perhaps an elevation. There are both domes, up-ramp, and down-dip, and each device must be measured using a total station, and the skill requirements are appropriately high. This undoubtedly increases the difficulty of construction, resulting in slow construction progress, and the human and material resources invested. Add to.

The structural layers of the project are also extremely complex. The structural layer mainly includes purlins, edges, angle steel, galvanized steel, insulation cotton, waterproof membrane, moisture barrier, butyl tape, sealant, waterproof dragon skeleton, color plate, etc. Each process must be connected to each other, the ring is tight Buckle, the quality requirements are very strict. Because the curtain wall is divided into five areas: an upturned surface, an inclined surface, a roof, a channel ceiling, and a corridor. Except that the roofing difficulty is relatively small, the construction pressure of the other two areas detects every device of the China Construction 2nd Bureau Corporation. Construction workers.
