| description | [Objective] The application of prefabricated interior partition（hereinafter abbreviated as PIP）walls in metro station projects is still relatively rare. Therefore, it is necessary to study the schemes and key technologies for this application. [Method] In view of the application scenarios of metro station projects, a complete set of application systems for PIP wall structures is proposed. The reinforcement design and splicing schemes of PIP walls are solved, the optimal structural form and structurally safe thickness，as well as the crack-resistance measures of PIP walls are determined and studied, and a full set of key technologies is formed. [Result & Conclusion] Under the premise of ensuring construction quality, the tensile strength of the prefabricated panel joints can reach or exceed the panel inherent tensile strength. There is no direct relationship between the tensile strength of the prefabricated panel joints and the compressive strength of the joint mortar. The out-of-plane flexural bearing capacity of the spliced panel specimens with a staggered joint distance of 900 mm is relatively weak, while that of the spliced panel specimens with a staggered joint distance of 600 mm is relatively strong. It is recommended that the material of PIP walls in metro stations adopt ceramsite concrete hollow partition wall panels. The proposed complete set of key technologies for PIP walls has been applied to the second-phase project of Xuzhou Metro Line 3. |
