Background
Climbing formwork (also called a creeping formwork in the external periodical) is a formwork technology suitable for the construction of cast-in-place reinforced concrete vertical or inclined structures, such as walls, bridges, towers and the like. Can be divided into a 'climbing formwork with a frame' and a 'climbing formwork without a frame'. The Chinese creeping formwork technology starts in the later 70 th 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. Three processes of 'mutual climbing of a template and a climbing frame', 'mutual climbing of the climbing frame and the climbing frame' and 'mutual climbing of the template and the template' are developed and formed step by step, and the first process is the most common process. The climbing formwork plays an important role in large pier column construction, and has the advantages of high construction speed, short period, convenience in operation and the like.
The climbing formwork used at the present stage still has partial defects, and is still not enough in the demolding process, when the surface of the formwork is separated from the concrete surface, the contact area of the formwork and the concrete surface is large, so that the separating force of the formwork and the concrete surface is large, and the phenomenon of uneven concrete surface is easily caused in the separation process. And the whole device is complex and is not beneficial to high-altitude operation.
