【Abstract】With the development of national economic construction， scaffolding in the construction of elevated stations has gradually developed and become more and more refined， and can be well applied to various types of construction sites. In recent years， the socket type coil buckle scaffolding has become the mainstream of cast-in-place construction method because of its high bearing capacity， high safety performance and high efficiency of erection and dismantling. Through the analysis of erection and acceptance of the socket type coil buckle scaffolding， this paper briefly describes the construction technology of socket type coil buckle full framing and discusses its application in the support of tall formwork.

1 工程概況

车站为高架站，包含站台、自动扶梯、无障碍电梯和疏散楼梯，车站北侧高架下方预留自行车停车场，车站站台中心里程为S（X）DK1+017.278，站台全长38m结构形式采用建桥合一。

联工车站施工方式为承插型盘扣式满堂支架，架体高度范围在8.5～10m，属于高支模体系，车站两侧为箱梁结构，箱梁高度1.7m，中间为T梁结构，T梁高度1.3m，结构剖面图如图1所示，全站需浇筑混凝土497m3，满堂支架基础采用50cm连砂石回填压实，然后浇筑20cm厚的C20混凝土作为满堂支架的基础。

2 施工部署和施工工艺

2.1 施工方案流程

地基处理→地基基础验收→施工放线→首个步距支架体系搭设→水平杆水平校正、立杆垂直度校正→逐个步距搭设→按规范设置竖向、水平方向剪刀撑→6m高度时进行第二次验收→验收合格继续上层架体搭设→搭设顶层水平剪刀撑→支撑体系搭设完成后进行验收→铺设主次龙骨→铺设模板→绑扎钢筋→混凝土浇筑前进行验收→浇筑混凝土→混凝土强度达到要求后满堂支架体系拆除。……
