Guangzhou Asian games stadium steel structure construction technologyIt is understood that the guangzhou Asian games will set up a total of 53 venues and 19 training venues, formation of the five group of Asian games venues, including 12 new venues. Asian games project belongs to the group of large and complex project, the structure is novel, strange shape and construction is difficult. Venue has special subject structure and outward appearance modelling design, summed up the application of new technology is of great significance.
Asian games sports complex engineering, tennis center, nansha gymnasium construction adopted many new technology. Among them, & other; Variable curvature of large area facing concrete wall template technology & throughout; , & other Double layer hub-and-spoke throughout a string of structural steel roof truss of prestressing technology & space; Have passed the identification of scientific and technological achievements, respectively, has reached the leading domestic level and the domestic advanced level, in order to write these two technologies as the core technology was named the 2009 guangdong provincial method the construction methods.
The yuncheng comprehensive stadium & ndash; & ndash;Steel structure constructionTemplate technology, clear water concrete wall
Guangzhou yuncheng highlight is the comprehensive gymnasium projectSteel structure constructionApplication, manufacture and installation of the hyperbolic annular space truss technology. Venues by comprehensive hall, gym, history museum and stroll the air corridor, a total construction area of 22126 square meters. Appearance to & other; Flowing ribbons & throughout; Scheme as building design concept, with elegant modelling symbol games friendship link, with the raft of Asian peace meaning emphasizes the close communion with the pearl river water system, express the poetry of lingnan landscape intention.
Venue subject for the cast-in-situ reinforced concrete frame structure, roof system using space combination steel truss structure, space combination truss span of 99 meters. Comprehensive gymnasium project total steel quantity reached more than 11000 tons, the component number more than 20000 pieces, complex structure of node, the component type, pipe truss, box girder, the cast steel nodes, H truss, etc. The modelling of steel structure is more complex. Gym steel structure modelling like turtles. Modelling of complex shape such as dolphins, steel roof system consists of steel column outer cylinder, inner strength sex column and primary and secondarysteel frameComposition. The project size is big, complicated structure, high accuracy requirement. Hyperbolic annular space truss production and installation, in the process of unloading will cause the structure stiffness change, have distribution of gravity changes. Engineering using digital simulation technology, the organic combination of computer and the traditional production process, solving the hyperbolic annular space truss production and installation of high accuracy requirement of the construction problem.
The gymnasium is another innovation of yuncheng area facing concrete wall template technology application. The building facing the characteristics of the concrete wall is concrete wall combined with peripheral changes the shape of the buildings, by multiple arcs in different curvature wall section and straight wall segments. Design requirements to achieve the effect of concrete wall. How to solve this problem? Project department according to the variable curvature area facing the construction characteristics of concrete wall and self innovation design is a set of targeted combination frame arc formwork supporting system, and make effective measures to solve the variable curvature of large area facing the perpendicularity of the concrete wall and the curvature of the control, the control of reinforced protective layer and the wall thickness, the facing concrete pouring, vibrating and leakproof slurry, etc.
Nansha gymnasium & ndash; & ndash; Double spokes space on a string of structural steel roof truss first applied in China
Double spokes space string structural steel roof truss, do not know of any cases of application in China, the prestressed construction also have no successful experience to draw lessons from. Nansha gymnasium with a total construction area of 30265 square meters, building a total height of 29 m, set the audience more than 8000, adopt the structure of concrete and steel structure combined with. Basis using prestressed pipe pile, concrete frame structure is used in the first layer and the stands roofing system for prestressed SuoGang structures, envelope mainly adopts hidden frame, glass curtain wall.
Double layer hub-and-spoke space string structure is developed in recent years a new type of large-span prestressed steel roof truss structure, steel roof truss by outside, inside two layers of a diameter of 98 meters, 41.6 meters circular pieces of string structure superposition. Steel roof truss in prestressed applied before, stiffness is insufficient, is not a stable structure, must build the temporary support system of steel roof truss is fixed. Finally, the project department after many arguments, adopted the external layer 2 batch 4 batch, to lining, each batch 9 steel cable tensioning schemes at the same time to succeed.
Construction and new technology like this: the Asian games tennis center project adopts double circular modelling of space combination inclined column construction technology, and new type wall materials of polystyrene particles insulation mortar construction technology, air source heat pump water heating technology. Asian games diving USES the new technology of high side whipstitch aluminum magnesium manganese outside curtain wall; Steel structure construction safety efficient integral hoisting method is adopted, and so on.

The double helix of blue white alternate with swimming, diving, shape looking like hakka tulou tennis center & hellip; & hellip; Guangzhou Asian games venues, new wins a sure-fire splash. Combines the modern design idea, construction technology in the integration of the Asian games construction projects is a stage, is also a window. Architectural, structural, physical process and other professional knowledge, need to various professional integration and the macroscopic grasp, in the actual operation process encountered difficult and endless. Test of large-scale construction is the construction technology, and promote the technological innovation of construction industry in China. ,
