在本文的案例工程中,采用了预应力掉拉多层外挑结构施工技术进行施工,在施工过程中利用大型的有限元软件ANSYS来对这一建筑工程的所需要优化的结构以及关键点进行模型建立工作。在这一基础之上,必须要采用科学合理的施工流程、测控方式、张拉控制应力、张拉实际、预应力损失以及理论伸长值等等,以此来提高工程质量,促进工程经济效益。本篇文章主要针对预应力吊拉多层外挑结构施工技术中的要点进行阐述,并对其中存在的难点提出了相应的建议,以期为其它建筑工程施工过程中提供参考。
In the case engineering of this paper, the construction technology of prestressed pull-out multi-layer external pick-up structure is adopted for construction. In the process of construction, the large-scale finite element software ANSYS is used to carry out the optimization of the structure and key points required for the construction project Model building work. On this basis, we must adopt a scientific and rational construction process, measurement and control methods, tension control stress, the actual tension, loss of prestress and theoretical elongation and so on, in order to improve the quality of the project and promote the economic benefits of the project . This article mainly elaborates the key points in the construction technology of the multi-layer structure of the prestressed crane and puts forward the corresponding suggestions to the existing difficulties in order to provide references for the construction of other construction projects.
