Steel structure is widely used in high floors and super high floors due to its seismic resistance. It can be completed in a short time that is compared with concrete during construction, which can effectively reduce costs. A building of steel structure is assembled from thousands or even tens of thousands of steel components. It is contained steel beam, steel plate, bolt, welding consumable and so on. It is a crucial decision how to quality control in every construction phase.
The steel structure must be managed independently from production to assembly. Material certification or test report is requested, including the process of steel remanufacturing, transport process, bolt pre-buried, steel column lifting, steel beam lifting, steel component locking, welding, touch up, steel plate laying, fireproof coating and each of stages. In the process of lifting the steel components, it is necessary to confirm the order of the hanging, whether to apply by the original plan in the process of construction. In addition, the safety of the hanging operation needs to ensure whether there are safety measures, whether there are steel cables or fixing parts, so that the structural behaviors of the steel column and steel beam before locking can be stabilized. This is to ensure the risk of exposure to high-risk workplaces is reduced. In addition, the locking and welding of steel components must be carried out more carefully, not only by visual inspection but also by tools. Non-destructive testing is also required to confirm that the construction quality meets the construction specifications.
The steel structure project not only has earthquake resistance, rapid construction and reduces environment hazards, but the cost is also high. The steel structure project accounts for 35% of the total cost of the case, so that implementation of management will reduce the cost of expenditure. Therefore, this study discusses each construction by the case. The stage is from steel structure construction planning, data submission and review, material approach management, construction operation process management, quality audit, construction points, and so on, in order to implement construction management.
