Compared with the traditional multi-ribbed beam structure system, it has natural advantages such as simple construction, short cycle, low cost, novel appearance, and reduced noise. At present, the development of formwork has mainly gone through two generations. The first generation of formwork uses disposable formwork, which is easy to fall off, return to alkali, break, have non-standard wall thickness and leak slurry during construction; the second generation of formwork is fixed with nails, the disassembly process is cumbersome, the secondary construction utilization rate is low, the construction cost is high and the cycle is long; in addition, whether it is the first generation or the second generation of formwork, it is often full or strip paving, that is, the bottom formwork is laid under the formwork as a whole or at intervals. Due to the lack of connection between the formworks, it is necessary to fill the gaps between the formworks with fillers such as bamboo plywood, wooden strips, and extruded strips before pouring to prevent the horizontal displacement of the formwork under the side pressure of concrete. This process makes the formwork construction process cumbersome and the demolding after pouring complicated.
