Cement Prefabricated House Installation
The installation process of cement prefabricated houses is rapid and relatively simple, usually taking only a few hours to complete the entire installation.
The installation efficiency of cement prefabricated houses is high, with the specific time varying depending on the size of the house and the complexity of its structure. For example, if a three-story villa uses nine prefabricated cement rooms, the on-site installation takes only about three hours; other reports indicate that the hoisting of an ordinary house can be completed within four hours. This efficiency stems from the industrial production mode of prefabricated components—all cement slabs, wall panels, and other components are precisely formed in factories using molds, with dimensional errors controlled to the millimeter level, eliminating the need for secondary processing during on-site assembly, which only requires simple splicing.
The installation process is typically divided into three stages:
1. Site Preparation and Component Transportation
Before construction, the foundation site must be leveled and the house layout determined. Subsequently, the prefabricated cement components (such as floor slabs, walls, stairs, etc.) are transported to the site. These components have pre-reserved connection interfaces (such as bolt holes, slots, etc.) in the factory to ensure rapid positioning on-site.
2. Component Hoisting and Initial Fixing
A crane is used to hoist large components (such as entire walls or floor slabs) to their designated positions, and workers perform initial fixing through methods such as slots, bolts, or welding. For example, the installation of prefabricated fences uses slots to fix the wall panels, and the wall connections of cement prefabricated houses may adopt a similar design, achieving stable splicing through concave-convex slots or metal connectors.
3. Detail Handling and Acceptance
After completing the main structure, the gaps need to be sealed (such as filling with waterproof mortar or sealant), and ancillary facilities such as doors, windows, and water and electricity pipelines are installed. Finally, an overall acceptance inspection is conducted to check structural stability, waterproof performance, and surface flatness.
Technical Advantages and Precautions
The standardized production of prefabricated components significantly shortens the construction period while reducing on-site wet work (such as concrete pouring), lowering dust and noise pollution. However, it is important to note that components must be protected from collision damage during transportation, and on-site assembly must strictly align the interfaces according to the design drawings; otherwise, it may affect structural safety. Additionally, the seismic performance of prefabricated houses must be ensured through reasonable design (such as adding seismic brackets).
