The production line is suitable for the production of simple components, such as truss reinforced laminated panels, double-sided laminated wall panels, flat wall panels and so on. There are three types of pipelines: manual, semi-automatic and fully automatic. With a single type and uncomplicated components, the assembly line can achieve a high level of automation and intelligence.
Long line method
The long-line method is generally found in the production of prestressed members, such as SP plates and double T plates.
Fixed mold table
The fixed mold table method can produce various components such as columns, beams, slabs, wall panels, stairs, bay windows, balcony panels, corner members, etc. It has wide application range, flexible and convenient, strong adaptability and less startup capital. Wide process.
The fixed mold base production components are “lying down” pouring, and the vertical mold production is standing and pouring. Prefabricated stairs are generally produced by vertical molds, and some factories use vertical molds to produce wall panels and columns without decorative finishes, doors and windows.
For prefabricated construction projects without a PC component factory in the vicinity, it is possible to level the site and produce prefabricated components required for the project.
Prefabricated components with large weights, complex shapes and extra-wide dimensions are inconvenient or even impossible to transport, using nomadic production methods.
In individual projects, vehicles with inconvenient components of the road will enter the construction site and will also adopt nomadic production.
Factory procurement or on-site prefabrication?
The component factory has a high degree of mechanization and automation, and can produce standard components in batches. It can also produce complex components with industrial workers, and the quality is controllable and stable. Compared to on-site prefabrication, factory procurement increases transportation costs and tax costs. Most of the Shanghai area is to purchase prefabricated concrete components from the factory.
Nomadic production of prefabricated components requires a site, and the total package unit needs to have the corresponding equipment and manpower, and the production capacity is limited. However, its investment is small and the construction period is short. The component has a short distance and low loss. Unified management of component production, installation and on-site construction. Nomadic production is suitable for projects with imperfect industrialization, small projects, and individual special projects.
Is the assembly line still a fixed die table?
The fixed die table method can be simply understood as moving the cast-in-place operation to the factory and producing various components, but the production efficiency is low and there is no room for growth in the future.
The production line of single-panel components can be automated and intelligent, and achieve high efficiency. But the investment is huge and requires a large market volume.
At present, the laminated slab and double-sided laminated shear wall can be highly automated, which is most suitable for assembly line production. The production of bay windows, formwork and reinforcement lashing are complex and suitable for production using fixed die tables. Ordinary wall panels are produced by assembly lines, and the production efficiency is improved to some extent.
