HPC保温一体化外墙板施工技术

Construction Technology of High Performance Concrete Integrated Exterior Wallboard

在中国人民大学通州校区西区学部楼项目中,外檐大面积应用HPC保温一体化外墙板。为保证HPC复合墙板生产加工效果,合理解决允许误差对钢结构和HPC结构的影响,确保板材安装精度,减少外檐渗漏风险,通过对幕墙系统挂接组件,将预制剪力墙构件转换为幕墙系统,并优化HPC复合墙板的风压变形性能、雨水渗透性能、空气渗透性能,满足了外围护结构要求。HPC保温一体化外墙板整合外檐装饰系统、保温系统、窗系统,减轻幕墙工程对工人技能、施工环境的依赖性。在工厂内预制HPC复合墙板,大大降低施工难度、有效提高施工效率。

In the construction of the department building of the west block on the Tongzhou Campus of Renmin University of China, HPC insulation integrated exterior wallboard is widely used in the outer eaves. The production and processing effect of HPC composite wallboard should be ensured, the influence of allowable error on steel structure and HPC structure should be reasonably solved, and the installation accuracy of plate should be ensured to reduce the risk of exterior wall leakage. Through the curtain wall system components, the prefabricated shear wall components were converted into curtain wall system, and the wind pressure deformation performance, rainwater permeability and air permeability of HPC composite wallboard were optimized to meet the requirements of external protection structure. And HPC thermal insulation integrated external wallboard converged the decoration system of external eaves, thermal insulation system and window system to reduce the dependence on workers’ skills and construction environment. Therefore, the prefabrication of HPC composite wall panels in the factory can greatly reduce the difficulty of construction and effectively improve the construction efficiency.
