摘　　要：针对铁路车站高架和雨篷管线密集,造型独特而造成清水混凝土木模板施工难度较大的实际情况,对铁路车站雨篷清水混凝土木模板的加固和重点构造体系进行了研究。通过对材料和加工设备的选择、模板排板进行方案策划,并针对站台异形柱、高架大型圆弧柱的模板设置和梁板交接阴角、墙板阳角的加固等重难点逐一制定相应的专项施工方案,顺利完成了施工,确保了清水混凝土的成形质量,为类似工程积累了经验。In view of the actual fact that the construction of fair-faced concrete wood formwork is more difficult due to the unique shape of elevated frame and awning with dense pipeline in railway stations,the reinforcement and key structural system of fair-faced concrete wood formwork of railway station awning are studied.Through the selection of materials and processing equipment and the scheme planning of formwork layout,aiming at the key and difficult points such as the formwork erection of platform special-shaped column and elevated large circular arc column and the reinforcement of internal corners of beam slab and external corners of wallboard,the corresponding special construction scheme is formulated one by one.The construction is successfully completed,the forming quality of fair faced concrete is ensured,and the experience is accumulated for similar projects.
