climbing formwork (i.e. climbing formwork) is a formwork technology suitable for cast-in-place reinforced concrete vertical or inclined structure construction, such as walls, bridges, towers and the like. The template climbing formwork can be divided into two types, namely a scaffold climbing formwork (namely a template climbing frame and a scaffold climbing formwork) and a non-scaffold climbing formwork (namely a template climbing formwork). The climbing formwork technology in China starts in the later period of the 70 s of the 20 th century, and is developed and applied in Shanghai; the 'frameless creeping formwork' is firstly used for the construction of cast-in-place reinforced concrete engineering of a main building of a new and universal hotel in Beijing in the 80 th century. At present, three processes of mutual climbing of templates and climbing frames, mutual climbing of climbing frames and mutual climbing of templates and templates are developed and formed step by step, wherein the first process is the most common process. Climbing formwork is a formwork process integrating the processes and characteristics of a large formwork and a sliding formwork, and has the common advantages of the large formwork and the sliding formwork. Is especially suitable for super high-rise building construction. It is the same with sliding formwork, depends on building vertical structure at the structure construction stage, and the successive layer rises along with the structure construction, and the template can not occupy the construction site like this, also need not other perpendicular transportation equipment. In addition, the scaffold is provided with an operation scaffold, and the construction has reliable safety enclosure, so that an external scaffold does not need to be erected, and the scaffold is particularly suitable for building multi-storey or high-rise buildings on narrow sites. However, the construction process used at present cannot implement the sectional flow construction, so the turnover rate of the template is low.
