Abstract
AbstractIn order to comply with the trend of global climate change, countries are gradually promoting energy conservation and emission reduction, and prefabricated buildings have become one of the main paths for the construction industry to develop towards carbon peaking and carbon neutrality goals. This paper takes the box-shaped column flange connection achieved by plug welding-core sleeve in the dormitory building of Tongzhou Campus of the Affiliated High School of Capital Normal University in China as the research object. Based on the consumption quota of prefabricated construction projects and the actual project quantity, the carbon emissions of steel structure column connection joints at different phases are calculated by the emission factor method, and it is proposed that the production consumption of building materials plays a key role in energy conservation and emission reduction. This paper concludes that the box-shaped column flange connection achieved by plug welding-core sleeve in the construction phase of an assembled steel building emits 49.5% less carbon dioxide than a conventional full fusion-welded joint. And the reason for the high carbon emissions of the latter is mainly from the amount of materials and machinery required for full penetration welding. It further affirms the green and environmental protection effect of the assembled steel structure plug welding-core sleeve flange connection joint in actual projects, and provides a reference for related research.
