Cost Control Analysis Of Large-span Heavy Steel Structure Workshop

As our country’s economy development entering the new normal stage, the demand for industry building in the field of heavy industry is developing towards the trend of larger span, higher carrying capacity, faster construction, less pollution to the environment and more economic. This text take the new large-span heavy steel structure workshop of a heavy equipment factory as the research object, study the cost control method through the analysis of design, making and installation stages of the steel structure workshop.At the design stage, through the comparative analysis of three different design schemes whose column space are respectively 6m, 9m and 12 m, the relation between column space and the steel consumption of steel columns, steel beams, crane beams, supporting system and purlins are studied. The research shows, the steel consumption of steel frames decreases with the increase of column space while the steel consumption of crane beams, supporting system and purlins increase with the increase of column space. And the steel consumption of the large-span heavy-duty steel structure workshop reaches the minimum when column space is 9m.At the making stage, the research shows, processing equipment and processing technology have remarkable influence to the making cost of steel structure. Using digital cutting technology and airless spraying can effectively save the making cost.At the construction stage, the research shows, installation procedure, hoisting scheme, installation technology, labor organizing and installation equipment have great influence to the installation cost. Both of reasonable labor organizing and scientific construction management can effective control the installation cost of steel structure.Through the design, processing, production, construction installation of three phases, consider the three elements of materials, artificial, construction machines and tools, proposed to the large-span heavy steel structure factory building cost control reasonable suggestions.The research results of this text can be referenced in the following construction of large-span heavy steel structure workshop.
