Background
The modular building (PPVC for short) means that the building is divided into a plurality of space modules, all devices, pipelines, decoration and fixed furniture in the modules are made, and the decoration of the outer facade can be finished. The module components are transported to a construction site, and the building assembled together just like building blocks is a high-end product of building industrialization and has high integrity.
As is well known, the construction site in the traditional construction field has environmental problems which are difficult to overcome, such as excessive dust, noise, water pollution, light source pollution, slurry treatment in the casting site, toxic and harmful smoke and waste gas treatment, densely-packed cylinders and high-altitude wastes, toxic and harmful soil backfill, mechanical vibration, garbage generated by personnel activities and the like, although various environmental laws and regulations are clearly specified in the building law and related construction regulations, the implementation of truly qualified and qualified regulations is very difficult.
The PPVC technology can effectively reduce various pollutions to the site caused by traditional building construction, and as most building components in the PPVC technology are finished in factories and only need to be hoisted and assembled in site construction operation, the unsolvable environmental problems can be easily solved, and the fact proves that the PPVC building has little pollution to the environment.
On the other hand, the PPVC technology has a plurality of advantages, such as high construction speed, and the construction period can be shortened by 50-70% compared with a large-plate building; the assembly degree is high (the assembly degree can reach more than 85 percent), most of the construction work, including installation of facilities such as water, heating, electricity, sanitation and the like and house decoration, is completed by moving to a factory, and the construction site can be used only by hoisting the rest components, processing nodes and connecting pipelines; unique assembly structure makes things convenient for later stage enlargement.

2. The modern construction machinery is trending towards the direction of automation and intelligence, while the existing PPVC internal mold is retained at the primary level of manual operation, the technical bottleneck needs to be broken through as soon as possible.
3. The angle plate structure of the existing PPVC internal mold is bonded with a top surface component, a side surface component and a rear component through concrete after pouring, and is difficult to take down in a manual mode, so that how to easily and laborsavingly separate the angle plate from the surface of the component becomes a difficult point of industrial technology.
