Quality Control of Construction Engineering of Dongguan Steel Structure Factory
1. Basic quality control. Although the steel structure workshop uses a large amount of steel as the main body of the frame construction, it still cannot be separated from the reinforced concrete structure in some basic engineering construction. And the reinforced concrete construction process used in the construction of the steel structure plant foundation project is exactly the same as the traditional process, so we must pay attention to the possible deviation of the anchor bolt. After the foundation construction is completed, there will be some deviations in the pre-buried level of many anchor bolts. In recent years, with the development of construction technology, the more representative construction in the world is the introduction of information management technology.
2. Subject quality control. In the main construction process, the design drawings and technical standards should be strictly followed and the construction should be carried out at a high standard. For example, the error between each anchor of the anchor bolt should be controlled within 2 mm, other errors should be controlled within 4 mm, and the construction should be accepted in strict accordance with the control standard. The main concerns are: the central displacement deviation of the foundation, the positional deviation of the embedded bolt, the settlement observation point and the completeness of relevant technical data. The process should be participated by all kinds of stakeholders of the project. For the problems found in the inspection, it should be communicated in time, and the agreed treatment opinions should be fed back to the project supervision, and the construction of the next process can be approved only after the proper treatment is confirmed. The most critical and most problematic part of the steel structure is the installation quality and welding quality of the steel structure. When installing the column, be sure to keep the column completely vertical. At the same time, when welding various parts of the steel structure, it is necessary to ensure the high quality of the welding. If there are unqualified welds, or where we think it is necessary to strengthen the welding strength, it is necessary to carry out reinforcement and repair in time, and carry out multiple inspections as key quality monitoring points in the subsequent construction. In addition, attention should also be paid to the construction of the entire main project. All technical data should be recorded, handed over and stored in a clear and traceable manner.
All in all, in recent years, steel structure construction has been favored by engineering construction personnel with its unique advantages, and has been widely applied to industrial plant construction. Safety is the top priority of the project. In order to ensure the safety of the project and to achieve the established project construction objectives, it is inseparable from the strict control of the construction quality. In summary, in the construction of steel structure industrial plants, the supervision and control of construction and installation quality should be strengthened, and relevant pre-planning, accidental filling and filling, and strict inspection afterwards should be done well. Relevant management personnel are required to formulate practical and implementable quality management measures, from high-standard procurement of raw materials to rational stacking of engineering materials, from accurate control of engineering construction links to strict completion of construction inspections. Quality control points. Through the above efforts, it is ensured that the construction quality deviation of the steel structure plant is effectively controlled, providing a solid and reliable guarantee for the subsequent safe and stable industrial production.
