Prefabricated steel workshop construction precautions
1. Reasonable selection of steel
In the construction of prefabricated steel workshop, it is very important to select reasonable steel. The task of steel selection is both important and necessary. There are many types of steel, so it is difficult to select the steel suitable for the construction of buildings from many types of steel, and the construction planning of today's buildings also has high specifications for steel.
Different buildings have different specifications for steel structure strength, deformation and fatigue stress, so it is also difficult to select. Therefore, in order to better use the effect of steel structure during the construction of prefabricated steel workshop, it is necessary to start from practice and select steel scientifically in combination with practical construction specifications.
2. Details of prefabricated steel workshop
The planning of steel structure workshop details generally has an important impact on the stability of the whole structure. Therefore, we must pay attention to the planning in this regard. It is required that planners should carry out practical accounting for the stress system and detailed nodes of the steel structure in the future when the plan of the steel structure project is clear, and scientific improvement should be made according to the specific situation.
As far as the planning of steel structure stress system is concerned, most buildings today use the bar structure. This structural steel must have a large strength grade, and the specification of the section must conform to the construction specification. It can be assembled on site during production, and the binding force between components is small. This requires that the construction personnel must master the planning key points in the planning link to ensure the stability of the connection between component nodes. The planning of detailed nodes must be detailed, because the planning content of detailed nodes is messy, it must be strictly planned, and should meet the practical construction needs.
3. Stability of steel structure engineering planning
Planners must first analyze the stability of the structure from the perspective of its integrity, and take into account the overall stiffness and instability of the steel structure. At present, the reduction coefficient method and the critical pressure solution method are used to calculate the stability of steel structures in planning. Generally, these two methods are also used to calculate the stability of axial compression members. Because the internal force of the steel structure will be affected by the large deformation of the flexible structure, when calculating the elastic stability, it is not only necessary to consider the structural integrity characteristics, but also need to consider the second order analysis. Planners cannot ignore this point.
During the construction of the prefabricated steel workshop, the planning of the steel structure project not only enables the construction project to have a larger span space, but also has the advantages of convenient equipment and low cost, which makes it more and more widely used in the construction project. Because of the deepening of the urbanization process, the number of high-rise buildings will increase rapidly, which puts forward higher requirements for the planning of steel structure projects.
