Cement Prefabricated House Construction Process
The construction process of cement prefabricated houses mainly includes three key stages: foundation treatment, installation of foundation piles and assembly of crossbeams, and subsequent construction.
Foundation Treatment: This is the fundamental step in building a cement prefabricated house. First, the foundation needs to be leveled, with weeds and other debris cleared away, followed by excavation of foundation pits. During this process, surveyors must strictly control the excavation depth and ground elevation to ensure they precisely meet design requirements. After excavating approximately 60 centimeters down, a layer of white plastic sheeting should be laid on the foundation. Its role is significant, effectively preventing water loss from the concrete, promoting the full progress of the hydration reaction, and thereby enhancing the strength and durability of the concrete. Subsequently, a concrete pump truck is used to pour the foundation. It is noteworthy that no steel reinforcement is used in this foundation.
Installation of Foundation Piles and Assembly of Crossbeams: After the concrete has set, the process moves on to installing the foundation plates. First, a drill is used to create holes in the foundation, and then expansion screws are used to firmly fix the foundation plates, whose role is to secure the foundation piles to the sub-base. Next, a mobile crane is employed to install the prefabricated foundation piles, which weigh about 5 tons each and have holes reserved at the four corners for easy lifting operations. The installation of crossbeams is akin to assembling building blocks. During the installation, horizontal measurements are taken and adjustments are made as needed. Once properly aligned, they are secured with nuts. To ensure structural stability, foam sealant is used to fill the gaps between the crossbeams and foundation piles, providing fixed support. At the same time, the areas where nuts are fixed are sealed with cement to prevent rusting of the nuts and corrosion of the connecting components, thereby extending the service life of the entire structure.
Subsequent Construction: After completing the framework of the foundation, backfilling of soil and pouring of the foundation are carried out. The crossbeams are quickly connected using mortise-and-tenon joints, and the installation of stairs is also as convenient as assembling building blocks. Afterward, a 5-centimeter-thick floor slab is laid, and finally, grouting is performed on the gaps between all components to make the entire house structure more compact and stable.
