Installation and Construction Technology of Prestressed Concret
For the large-span roof truss,installation is the most important process,which will have a decisive impact on the quality of the whole project.A grain storage construction project needs to lift the prestressed concrete roof truss.On the basis of summarizing the basic situation of the project,the preparation process before the roof crane is analyzed,including the lifting requirements of the roof truss,the lifting process of the roof truss,the setting of lifting point,the selection of wire rope and the determination of crane performance.The installation and construction technology of roof truss is studied in detail from the two aspects of formwork and lifting,which must be strictly according to the design and construction requirements.Finally,the installation quality assurance measures of the roof truss are introduced.
