Problems solved by technology

However, in practical applications, the prefabrication rate is one-sidedly pursued in buildings, especially the load-bearing structure also adopts prefabrication technology, which leads to poor seismic and crack resistance performance and hinders the development prospects of the market
At the same time, with the cultural needs of modern buildings, traditional precast concrete wall panels still have the problem of single surface decoration effect or the need for secondary decoration construction. The popularization of precast concrete wall panels is affected. Prefabricated prefabricated wall panels with excellent performance to fill this gap

Abstract

The invention relates to a fiber-reinforced cement composite concrete prefabricated building component (PC-FRC) and its production method, which is suitable for building exterior wall decoration, building structure enclosure, energy-saving and thermal insulation projects, and is especially suitable for prefabricated housing industrialization projects. It is suitable for people's livelihood fields such as natural disaster emergency response and post-disaster reconstruction. Including decorative surface layer, fiber-reinforced cement layer, concrete structure layer, insulation layer and steel skeleton; fiber-reinforced cement layer is compounded on the decorative surface layer, and fiber-reinforced cement layer is connected with concrete structure layer; insulation layer is laid in the concrete structure layer , the insulation layer is completely wrapped by the concrete structure layer; a steel skeleton is also laid in the concrete structure layer. Fiber-reinforced cement layer, thermal insulation layer and concrete structure layer are compositely molded in molds with shapes. There are exposed steel bars on the surface connection parts of the prefabricated building components, which are used for the connection between the prefabricated parts and the building structure during building assembly; the hoisting embedded parts are laid on the concrete structure layer.
