The project design move feeling, light steel structure construction should not only guarantee the "excessive weight", and "plate strong enough". How to more than 5000 root is not par 1500 nodes of different size and personalized design and manufacture of perfectly together is a big problem, according to zhongjian steel structure design personnel, after they studied the over and over again, from the cellular and creatively USES the internal and external double-layer hollow prism six node form, effectively reduce the weight of a quarter, connection and structure stability. In the manufacturing process, the project also "encounter" to a lot of difficulties.
Steel structure engineering project are each node by six kinds of specifications for a total of 48 parts board spellers, ranging from 40 cm to 100 cm in diameter, weld article number from 40 to 50, zhongjian steel structure manufacturing personnel, according to the welding of this node is in embroidery, however, weld optimization measures are optimized by the concentric circles positioning, effective will strictly control the manufacturing precision error in British standard specification requirements within 3 mm. During the installation process, the use of point supporting system in a small space in the force transmission path through 144 points to ensure clear, at the same time, 3 d coordinate method is used to control well the installation accuracy.
