          Guangzhou Steel News: CAEXPO main stadium steel project completed "Peacock" On screen faceless

          Recently, the 2015 CAEXPO main venue - the Kunming International Convention and Exhibition Center project steel construction has been all over, June 1 to 3 trial will show, beautiful large "Peacock" finally opening screen to show his face.
          Kunming International Convention and Exhibition Center project Steel Works Co., Ltd. invested by a certain Yunnan, a Steel Co., Ltd. is responsible for the external grid Steel Detailing plans, production, installation, including outside the arc, inner arc, main sequence hall, the four main walls column partition, spaced 530 meters north-south, east-west spaced 900 meters, the exhibition hall for up to 1500 meters peripheral week, spot steel mesh volume 1.1 million tons, in September 27, 2014 began lifting, and in January 29, 2015 capping two days in advance, which took 125 days. Guangzhou Steel
          Secret-ASEAN Expo venue plan concept
          Kunming International Convention and Exhibition Center project semicircular steel grid distributed to the peacock as a prototype program, combined with geographic and climatic characteristics of Kunming, set up steel mesh gray space ("gray space", also known as "pan-space" transitional space between the external environment and their means of construction in order to achieve the purpose of integration of indoor and outdoor), creating a strong, brilliant lighting effects. Each single arch outside the arc grid by only four fulcrum, each arch Pairwise connected, such as the peacock, beautiful; a number of grid points within the structure arc east and west sides, unilateral span of about 240 meters, in the middle with joints, rope tightly package, such as peacocks double axillary, shame shame afraid to show people; the main sequence hall span nearly 350 meters, is the most difficult part of the entire grid structure, Majestic, such as a singing peacock head.
          Bending and torsion member sheer number of similar projects in the country in the first place
          Kunming International Convention and Exhibition Center steel works using domestic rare, Yunnan's first variable cross-section of bending and torsion of thin-walled shaped space all welded construction using steel members are all members of bending and torsion, for a total of more than 4100 pieces of components, bending and torsion number of member congregations in the country similar projects in the first place, and the viewpoint of bending and torsion of each member, there was no common direction. In particular vases, bending twist unprecedented degree, described as "like a column of non-column, non-beam like beam."
          CAEXPO main stadium the largest steel works span 104 meters, maximum 34 m, the largest slice weight 30 tons, the total amount of 1.1 million tons of steel, is divided into a grid outside the arc, while the grid, the grid in the arc of three parts . 14 arcs and the inner arc grid 13 grid arced outer arc, plus both ends of the two side mesh arcs, the 13 pavilions package rope. Wherein the inner arc of the grid at the highest arch hall provided the main sequence, the pavilion main imports. Main sequence hall walls hung in a tree on 30 steel columns, tree column due to a larger force, the use of high construction steel Q420 level. Chamber set up two huge vases, vases, 24 meters high, each 123 vases made of steel components assembled, each bar weighing 163 tons, the degree of bending and torsion vases shall also be a Yunnan most. Cylinder vase hall of the main sequence phase top mesh perfectly, hall roof grid plan idea closely, showing Queling chic feather effect, and see-through sky.
          Construction of new stadiums in the end how hard?
          Because steel mesh bending and torsion member are shaped space during planned to deepen the difficulties. Due to planned outside party given only summarize coordinate, causing members to find appropriate form huge workload, deepen plot is hitting 1.3 million coordinate points, convention Steel Detailing software (such as Xsteel) simply can not meet the requirements to deepen. Steel for the construction of the project, the independent research and development of a secondary development of software-based CAD channels were set up and a graph model. The project is invested 45 familiar bending and torsion member deepen personnel, appropriate to nine times the size of the practice with the project.
          During component production, using a pay-off given to tire standards expected under CNC control size, strict compliance processes to welding, assembly and other fight back tire testing process to ensure a high component precision control requirements. Delivery process, the use of advanced networking technology, provided ID to each member of each steel member tracking, and comprehensive survey developed transport routes, to ensure the timely arrival member. Guangzhou Steel
          During the member device, pre-slab bearing capacity by calculation, carried out structural reinforcement, to ensure that the two 150t crawler crane large floor safe operation; large crane foundation through independent program completed D1100 special heavy lifting crane central floor; construction Process plan new measures send a clear formula to adjust tire assembly racks. From the production to the unit, a number of construction workers are the primary method used in Yunnan Province, successfully completed ahead of cap-ASEAN Expo steel mesh structure.
